NCLEX Physiological Adaptation Practice Test

Q: What does Physiological Adaptation cover on the NCLEX?

It focuses on acute and unstable conditions, complications, and emergency responses when the patient’s body is not compensating well.

Q: What is the best approach to shock or bleeding questions?

Choose actions that support airway, breathing, and circulation, monitor closely, and escalate care quickly when signs point to instability.

Q: Do respiratory distress questions show up often in this set?

Yes. Expect scenarios where breathing changes fast and you must act quickly, monitor oxygenation, and prioritize interventions.

Q: How do I handle questions where I want to do many things at once?

Pick the first action that prevents the most harm, then the next steps that support ongoing monitoring and escalation.

Q: How should I use this practice test to improve quickly?

Take it once to find weak patterns, review the concept behind each miss, then retake a short set to confirm improvement.

Q: Are questions in this set mostly emergency situations or can they be slower changes too?

Mostly emergency or fast-changing situations, but you may also see “getting worse over hours” cues where the right answer is early intervention before it becomes a crash.

Q: What kinds of symptoms are the biggest red flags in Physiological Adaptation questions?

Sudden breathing trouble, sharp drops in blood pressure, new confusion, chest pain, uncontrolled bleeding, and signs of poor perfusion are common cues that push you toward urgent actions.

Q: How do I decide when to call the provider vs intervene first?

If the patient is unstable, complete the immediate safety action first (ABCs, oxygen, positioning, stop the cause when possible), then escalate. If the patient is stable but trending worse, report early with clear data.

Q: Do these questions test fluid and electrolyte emergencies too?

Yes. You can see situations where abnormal fluid balance or electrolytes create dangerous changes that require priority responses.

Question 1

A 16-year-old sexually active female patient with a history of pelvic inflammatory disease (PID) presents to the emergency room with complaints of sudden right-sided lower abdominal pain and gastrointestinal distress. She cannot recall the date of her last menstrual period, but states she knows that she’s “late.” Her exam demonstrates a unilateral, right adnexal mass. The nurse knows that this patient likely has which of these prenatal complications?

Accepted Answer

ectopic pregnancy. The presentation of sudden, unilateral pelvic or abdominal pain, amenorrhea, and a tender adnexal mass is highly suggestive of an ectopic pregnancy. Additionally, this patient’s history of PID puts her at an increased risk for this disorder. Spontaneous abortion presents with bleeding and passage of the products of conception before 20 weeks gestation. It is usually painless, although the uterus may be tender to palpation. Gestational trophoblastic disease (GTD) is a condition that refers to a number of conditions, both benign and malignant, that can arise from the placenta. GTD will usually present with vaginal bleeding, along with symptoms of severe morning sickness and pre-eclampsia-like symptoms prior to week 20 of gestation. Premature rupture of membranes or PROM is rupture of the amniotic sac prior to 37 weeks gestation. It is painless and presents with the sudden release of varying amounts of amniotic fluid from the vagina.

Question 2

A nurse is on-call after hours for a pediatric clinic. A parent calls and states that her 1-year-old child has a fever of 104ºF. She asks the nurse what can she do until she can bring the child in for evaluation in the morning. Which of these recommendations is incorrect for this patient?

Accepted Answer

Administer aspirin based on the manufacturer’s weight-based recommendations. The nurse should advise this patient’s mother to provide supportive measures to ensure the child’s comfort and to reduce the bodily temperature. This may include bathing the child in tepid water, dressing them in light clothing, and encouraging fluid intake. The recommendation to administer safe over-the-counter medications for fever reduction such as acetaminophen (Tylenol) or ibuprofen (Advil, Motrin, etc.) based on the manufacturer’s weight-based recommendations can be given, but aspirin should not be given to children due to the increased risk of Reye’s syndrome.

Question 3

When considering the source of a postoperative fever, the nurse knows that which of these is usually not a likely source?

Accepted Answer

dehydration. Dehydration is not a likely source of postoperative fever. Fever in the days following a surgical procedure usually come from one of the following sources which can be remembered by the pneumonic “the 5 W’s”: pneumonia (Wind), urinary tract infections (Water), incision/wound infection (Wound), thrombophlebitis—either lower extremity/deep vein thrombosis or superficial/intravenous catheter—(Walking), drug allergies/postoperative abscess (Wonder drug/Whopper).

Question 4

Among these disorders, identify the one that is improperly matched with the electrolyte imbalance.

Accepted Answer

diabetes insipidus (DI) and hyponatremia. The improperly matched disorder and electrolyte imbalance is diabetes insipidus (DI) and hyponatremia. In DI, there is either a deficiency of or resistance to antidiuretic hormone. This causes intense diuresis with large amounts of water loss. As a result, the serum sodium level will rise. Therefore, DI is usually associated with hypernatremia or elevated serum sodium levels. Hyperparathyroidism results in excess production of parathyroid hormone. This triggers the demineralization of bone with the release of calcium and increased serum calcium levels. Addison’s disease or chronic adrenocortical insufficiency is characterized by diminished function of the adrenal cortex to secrete cortisol and aldosterone. Hypoaldosteronism is the main driver of hyperkalemia. Syndrome of inappropriate antidiuretic hormone (SIADH) is the overproduction of antidiuretic hormone that results in the impaired excretion of water. If the amount of fluid intake is greater than the reduced amount excreted, serum changes in sodium will occur as a result of the excess fluid. As a result, hyponatremia is common in this disorder.

Question 5

A nurse is caring for a patient with severe renal impairment. The patient has an intravenous catheter and is receiving fluids per the physician’s order. On a routine check, the nurse notes the patient is dyspneic, and the patient states that he feels short of breath. The nurse suspects fluid overload. Which of these other physical findings would help to confirm the nurse’s suspicion?

Accepted Answer

basilar crackles and rales. Patients with renal, heart, and/or hepatic impairment may be at risk for fluid overload or hypervolemia. Physical findings of hypervolemia include shortness of breath and dyspnea, adventitious breath sounds such as basilar crackles and rales, peripheral edema, ascites/distended abdomen, increased jugular venous pressure, tachycardia, hypertension, and a strong/bounding pulse.

Question 6

A 35-year-old male is brought to the emergency room by his wife. She states that he’s had the “stomach flu” for the past 2 days with severe diarrhea and vomiting. During the interview, the patient tells the nurse that he’s weak and fatigued. He also complains of lightheadedness, muscle spasms, as well as numbness and tingling in his extremities. The nurse is the first to review the laboratories ordered by the practitioner. Based on the patient’s history and symptoms, which of these results should the nurse report immediately to the ordering practitioner?

Accepted Answer

Potassium (K⁺) of 2.6 mEq/L. This patient presents with symptoms of hypokalemia. Potassium deficits can occur through loss via the gastrointestinal system (diarrhea/vomiting) as well as with laxative and diuretic use. The normal serum potassium level is 3.7 to 5.2 mEq/L, and a level that is lower than 2.5 mEq/L requires emergent intervention in order to prevent cardiac complications. The other laboratory values given are within normal limits.

Question 7

A nurse is working on the telemetry unit when one of her patients suddenly exhibits Torsades de Pointes. The nurse knows that which of these is true about this arrhythmia?

Accepted Answer

It can be short-lived and self-limited without any treatment, but it can lead to ventricular fibrillation if not corrected and treated. Torsades de Pointes is a potentially dangerous arrhythmia that may be short-lived and self-limited without any treatment. It can be triggered by hypokalemia and hypomagnesemia as well as certain tricyclic antidepressant medications. Patients are usually tachycardic and will exhibit physical signs of nausea, shortness of breath, chest pain, and loss of consciousness if prolonged. Torsades de Pointes can progress to ventricular fibrillation if not treated and corrected. The classic EKG findings include a prolonged QT interval and a QRS complex that twists around the baseline. Treatment consists of the administration of magnesium or beta blockers along with cardioversion and/or temporary atrial or ventricular pacing. Initiation of CPR and ACLS protocols are indicated with progression to ventricular fibrillation.

Question 8

The nurse is assessing the electrocardiogram (EKG) reading of an elderly woman who has presented to the urgent care clinic with complaints of chest tightness, dyspnea, fatigue, and “fluttering” in her chest. The nurse should identify this rhythm (shown in the attached visual) as which of these?

Accepted Answer

atrial fibrillation. Atrial fibrillation is a common arrhythmia in the elderly and in those with hypertension, heart failure, valvular disease, and coronary artery disease. There are other clinical scenarios in which it may develop as well. Symptoms can include fatigue, dyspnea, shortness of breath, chest tightness, and palpitations. Dizziness, confusion and syncope may also occur. The EKG finding will show an irregular rhythm with no discernable p-waves. The QRS complexes will be uniform and vary in duration between 0.06 and 0.12 seconds. Atrial flutter will show similar QRS complexes as atrial fibrillation, but the p-waves will have an irregular “sawtooth” appearance. Normal sinus rhythm will show one p-wave per QRS complex and have a regular RR interval. Supraventricular tachycardia will show a rate of 150 to 250 beats per minute and p-waves will be present although they may not be visible due to the rapid QRS complexes.

Question 9

A nurse is working in an indigent health clinic and has been asked to counsel and educate a patient undergoing treatment for latent tuberculosis infection with isoniazid for 9 months. Which of these is correct information for the nurse to give this patient regarding his disease and treatment?

Accepted Answer

The patient should take vitamin B6 (pyridoxine) in order to reduce the risk of peripheral neuropathy while taking isoniazid. Latent tuberculosis infection (LTBI) is asymptomatic in approximately 95% of cases, and it is not considered to be infectious or spreadable to others as the bacterium is inactive in the lung. However, treatment is necessary as LTBI can convert to reactivation tuberculosis illness (infectious and symptomatic) in the setting of immune compromise. While there are a few drugs/regimens that can be used to treat LTBI, isoniazid for 9 months is commonly used. The most common side effects are hepatitis and peripheral neuropathy. The latter can be avoided with the coadministration of vitamin B6 (pyridoxine). Optic neuritis is a common complication of ethambutol therapy, which is typically only used in combination/multiple drug therapy for active tuberculosis.

Question 10

A nurse is caring for a patient with dilated cardiomyopathy who is hospitalized for an acute flare of congestive heart failure (CHF). The patient has symptoms of fatigue, weakness, and dyspnea. The nurse notes peripheral edema as well as coolness and pallor in the distal extremities. Given this patient’s physiologic status, which of the following nursing interventions would be indicated? Select all that apply.
A. Teach and encourage the patient to perform appropriate light exercise interspersed with frequent rest periods.
B. Teach and encourage the patient to perform coughing, deep breathing, and incentive spirometry exercises.
C. Provide appropriate analgesia for occurrences of chest pain and give supplemental oxygen as indicated per the practitioner’s orders.
D. Take proper precautions to protect the patient from falls and injuries during transfers and ambulation.
E. Elevate the lower extremities to reduce peripheral edema and improve circulation with the use of sequential devices of TED hose.

Accepted Answer

A, C, D, and E. Patients with dilated cardiomyopathy and congestive heart failure do not require coughing, deep breathing, and incentive spirometry exercises. These are indicated in patients with exudative respiratory disorders and immobile patients. Although acute exacerbations of CHF may cause pulmonary vascular congestion, the main pathophysiologic principle that produces the patient’s signs and symptoms is reduced cardiac output. All of the other nursing interventions presented are appropriate for this patient.

Question 11

A nurse is caring for a patient who just had an arterial line surgically placed in the femoral artery. Preoperative vitals showed a normal heart rate and blood pressure. The nurse knows that if the patient were to suffer the unexpected complication of an inadvertent puncture of the artery, she would most likely see which of these changes in this patient’s vital signs?

Accepted Answer

increased heart rate and decreased blood pressure. Inadvertent puncture of a vessel is a known complication of surgical arterial line placement. The subsequent hemorrhage will cause the patient to exhibit signs of hypovolemic shock including a decreased/low blood pressure and increased heart rate/tachycardia.

Question 12

A nurse is educating a female patient on her recent diagnosis of chronic obstructive pulmonary disease (COPD). Which of these patient statements shows that she needs further education about her disease?

Accepted Answer

“My lungs will heal if I use all my inhalers as directed.”. COPD is a pathophysiologic syndrome that includes both emphysema and chronic bronchitis. Patients may and often do have features of both. As the name implies, COPD is an obstructive airway disorder in which permanent structural changes and damage occurs in the lungs. The goals of management include both improving a patient’s functional state and relief of symptoms. Smoking is usually the most frequent contributory cause, and cessation is essential to proper management. Exertional dyspnea is common, so activity modification and rest breaks should be encouraged. Secondary infections are common so pneumococcal and influenza vaccines should be given yearly. Patients are usually given anticholinergic and short-acting bronchodilators as these help control airway inflammation and ease dyspnea. The statement, “My lungs will heal if I use all my inhalers as directed” shows that this patient doesn’t understand the permanent and often progressive nature of COPD and that she needs further education.

Question 13

A 72-year-old female is admitted to the hospital for community-acquired pneumonia. At the time of admission, she is dehydrated, hypotensive, complains of weakness, and has a productive cough with thick, green sputum. She has a history of diverticulosis, but is otherwise healthy. She is started on a course of IV levofloxacin and on day 4 of treatment, begins to have diarrhea. The nurse knows that which of these places this patient at the greatest risk of Clostridium difficile (C. diff) infection?

Accepted Answer

hospital admission. Antibiotic-associated colitis is a potentially dangerous problem that is almost always caused by Clostridium difficile infection. Hospitalized patients are the most susceptible, especially those who are malnourished or severely ill. C. diff colitis typically causes diarrhea in those hospitalized for more than 3 days. Infection usually resolves spontaneously after the antibiotic is discontinued. Other underlying infections such as community-acquired pneumonia, diverticulosis, and advanced age are not risk factors for antibiotic-associated colitis.

Question 14

The nurse has been ordered to perform gastric lavage on a patient. The nurse knows that which of these statements is correct regarding gastric lavage?

Accepted Answer

Gastric lavage should not be performed on an unconscious patient or a patient with an impaired gag reflex unless an endotracheal tube is placed first. Gastric lavage may be used to remove toxic substances from the stomach. Because this procedure places an unconscious patient or a patient with an impaired gag reflex at a high risk for aspiration, the airway must be secured with an endotracheal tube prior to the procedure. Patient positioning is important and should be the first step in the procedure after confirming the order and identifying the proper patient. High fowler’s is generally preferred. The proper length of the nasogastric tube is found by measuring from the nose to the earlobe and then to the tip of the xiphoid process. The nurse should always confirm the placement of the nasogastric tube prior to the administration of the ordered solution. This may be done via auscultation of an air bolus, but the preferred method is with a chest radiograph (x-ray).

Question 15

A 23-year-old male presents to the emergency department with complaints of progressively worsening abdominal pain and nausea over the past 12 hours. The nurse takes his vital signs and notes that he has a fever. The abdomen examination reveals a somewhat rigid abdomen with guarding and extreme tenderness in the right lower quadrant midway between the umbilicus and the superior iliac spine. Normal bowel sounds are present. Based on this history and presentation, which of these medical emergencies should the nurse suspect?

Accepted Answer

acute appendicitis. This patient presents with the classic history and findings of acute appendicitis. While pain may be diffuse or periumbilical early, classic appendicitis pain localizes in the right lower quadrant at McBurney’s point (midway between the umbilicus and superior iliac spine). The treatment is emergency appendectomy. Failure to treat in a timely manner may lead to rupture, peritonitis, sepsis, and death. Intussusception usually occurs in children (95% of cases) and is caused by ischemia due to invagination of a proximal part of the bowel into a section distal to it. Signs and symptoms include colicky abdominal pain, blood and mucous mixed stools (currant jelly stools), fever, and vomiting. Peritonitis is an infection and inflammation of the peritoneal cavity due to contamination from gastrointestinal products. While the signs and symptoms may be similar to appendicitis, the patient’s vitals will likely be abnormal due to shock (tachycardia, tachypnea, etc.) In addition, bowel sounds are likely to be decreased or absent. The history should also support an underlying cause (i.e., prolonged appendicitis, diverticulitis, etc.) An acute gastrointestinal bleed will likely present with signs of hypovolemic shock (abnormal vitals), and the patient may or may not be febrile and will have evidence of blood in the stool or frank hematochezia.

Question 16

Which of the following statements are correct concerning the medical emergency of retinal detachment?
Select all that apply.
A. Without emergent ophthalmic evaluation, surgical intervention, and correction, permanent and total blindness may result.
B. Immediate interventions include placing the patient in a supine position with the head turned toward the side of the affected eye.
C. Patient history includes a sudden, painful, and complete loss of vision.
D. Retinal detachments may occur either spontaneously or following trauma.
E. The elderly, greater than 85 years of age, are at the highest risk for retinal detachment.

Accepted Answer

A, B, and D. Retinal detachment typically presents with a history of sudden, painless blurred or blackened vision that usually occurs over minutes to hours. Patients will often describe the loss of vision as a “shade” being pulled down over their eye from top to bottom. A sudden painful and partial/complete loss of vision should raise the suspicion of angle-closure glaucoma. Retinal detachment is most common in people over the age of 50, though age is not the sole risk factor. Clients at risk for retinal detachment include history of retinal detachment, extreme nearsightedness (high myopia), previous cataract surgery, eye disease, and eye injury.

Question 17

A 52-year-old male with type II diabetes has blood pressure readings between 125/84 and 134/92 mm Hg. His urinalysis shows no abnormalities. He is prescribed an ACE inhibitor. Based on what the nurse knows about this class of medications, which of these would be an abnormality found on his serum chemistry as a result of being on this medication?

Accepted Answer

hyperkalemia. Due to the increased potassium retention that is caused by the ACE inhibitor class of medications, hyperkalemia is the best answer. While hypernatremia is potentially possible with ACE inhibitor therapy, it is generally not seen clinically. ACE inhibitors do not affect glycemic control. This patient may develop hypomagnesemia if his renal function declines, but not from this medication specifically.

Question 18

Which of these is not considered one of the six stages of viral growth?

Accepted Answer

the log stage. The log stage is not one of the six stages of viral growth. The log phase is one of the four phases of bacterial growth. The six stages of viral growth include: the attachment stage, the penetration stage, the uncoating stage, the replication stage, the self-assembly stage, and the release and lysis stage.

Question 19

An 82-year-old patient with advanced Alzheimer disease is brought in by his daughter for a concern about a new medication. She states that since he started taking Haldol for increasing psychotic behavior, he has began having bizarre movements. The nurse knows that this drug can cause which of these behaviors?

Accepted Answer

opening and closing of the mouth and repetitive, rhythmic tongue protrusion. Haldol is a psychotropic medication that can cause the adverse effect of tardive dyskinesia with either short-term or chronic use. Tardive dyskinesia can manifest as repetitive, rhythmic, stereotypic movements of the face, mouth, tongue and sometimes the limbs and trunk. Brief, intermittent, repetitive localized muscle twitches of the face describes facial tics. Occasional, brief but sudden jerks of the extremities especially when falling asleep can occur in normal people and are generally not a side effect of medication(s). Brief but erratic and irregular movements that interrupt normal motion describes chorea which is not an adverse effect of medication.

Question 20

A patient admitted to the hospital with an idiopathic spontaneous pneumothorax was successfully treated with a tube thoracostomy. The nurse is preparing him for discharge. He asks what the likelihood is that he will have this problem again. What is the most accurate response that the nurse should give this patient?

Accepted Answer

Recurrence occurs in up to 30% of patients and can be treated by obliterating the pleural space. Spontaneous pneumothorax recurs in 30% of patients typically within 2 years. Treatments of recurrent episodes differ in that they generally involve the administration of noxious agent(s) to obliterate the pleural space, abrasion of the pleural surface or partial pleurectomy to prevent further recurrences. There is no evidence to support that a recurrence heals more quickly than an initial spontaneous pneumothorax. Those who do experience a recurrence have a 70%–80% chance that they will go on to experience yet another episode. Tension pneumothorax typically develops in patients receiving mechanical ventilation or who have experienced penetrating trauma, not previous idiopathic spontaneous pneumothorax.
