NCLEX RN Exam Review Answers
1. A patient is being admitted to the ICU with a severe case of encephalitis. Which of these drugs would the nurse not expect to be prescribed for this condition?
- A. Acyclovir (Zovirax)
- B. Mannitol (Osmitrol)
- C. Lactated Ringer's
- D. Phenytoin (Dilantin)
Correct answer: C
Rationale: In the treatment of encephalitis, medications like Acyclovir and Phenytoin are commonly prescribed. Acyclovir is an antiviral medication used to treat viral infections like herpes simplex virus, which can cause encephalitis. Phenytoin is an antiepileptic drug that may be used to manage seizures associated with encephalitis. Mannitol is a diuretic used to reduce intracranial pressure (ICP) by decreasing cerebral edema. Lactated Ringer's solution, on the other hand, is primarily used in fluid replacement therapy and may not be indicated if a patient is at risk for high ICP, as excessive fluid administration could worsen cerebral edema and increase ICP.
2. The nurse is caring for a newborn with a suspected diagnosis of imperforate anus. The nurse monitors the infant, knowing that which is a clinical manifestation associated with this disorder?
- A. Bile-stained fecal emesis
- B. The passage of currant jelly-like stools
- C. Failure to pass meconium stool in the first 24 hours after birth
- D. Sausage-shaped mass palpated in the upper right abdominal quadrant
Correct answer: C
Rationale: Imperforate anus is the incomplete development or absence of the anus in its normal position in the perineum. Failure to pass meconium stool within the first 24 hours after birth is a key clinical manifestation associated with this disorder. This finding should prompt further assessment to confirm the suspected diagnosis. Other assessment findings in imperforate anus may include absence or stenosis of the anal rectal canal, presence of an anal membrane, and an external fistula to the perineum. Options A, B, and D describe findings typically noted in intussusception, a different condition characterized by bowel obstruction and telescoping of the intestines that can present with bile-stained fecal emesis, the passage of currant jelly-like stools, and a sausage-shaped mass palpated in the upper right abdominal quadrant.
3. What drives respiration in a patient with advanced chronic respiratory failure?
- A. Hypoxemia
- B. Hypocapnia
- C. Hypercapnia
- D. None of the above
Correct answer: A
Rationale: In patients with advanced chronic respiratory failure, such as those with chronic obstructive pulmonary disease (COPD), the respiratory drive shifts from being primarily stimulated by high levels of carbon dioxide (hypercapnia) to being driven by low oxygen levels (hypoxemia). This shift is due to the body's adaptation to chronic respiratory acidosis and hypoxemia. As a result, hypoxemia becomes the primary stimulus for respiration in these patients. Hypocapnia, a low level of carbon dioxide, is not a common driver of respiration in patients with advanced chronic respiratory failure. Therefore, the correct answer is hypoxemia.
4. A client was recently diagnosed with diverticulosis. What types of foods should the nurse recommend for this client?
- A. Whole grain cereal
- B. Eggs
- C. Cottage cheese
- D. Fish
Correct answer: A
Rationale: Diverticulosis is a condition characterized by small protrusions in the intestinal tract. To manage diverticulosis, a high-fiber diet is recommended. Foods rich in fiber help prevent constipation and reduce the risk of inflammation in the intestines. Whole grain cereals are an excellent source of fiber and can aid in maintaining bowel regularity. Eggs, cottage cheese, and fish are not high-fiber foods and may not provide the necessary dietary support for a client with diverticulosis. While protein-rich foods like eggs and fish are beneficial for overall health, they are not the primary recommendation for managing diverticulosis.
5. A patient with pneumonia has a fever of 101.4 F (38.6 C), a nonproductive cough, and an oxygen saturation of 88%. The patient complains of weakness, fatigue, and needs assistance to get out of bed. Which nursing diagnosis should the nurse assign as the highest priority?
- A. Hyperthermia related to infectious illness
- B. Impaired transfer ability related to weakness
- C. Ineffective airway clearance related to thick secretions
- D. Impaired gas exchange related to respiratory congestion
Correct answer: D
Rationale: The correct answer is 'Impaired gas exchange related to respiratory congestion.' While all the nursing diagnoses are relevant to the patient's condition, the priority should be given to impaired gas exchange due to the patient's low oxygen saturation level of 88%. This indicates a significant risk of hypoxia for all body tissues unless the gas exchange is improved. Addressing impaired gas exchange is crucial to ensure adequate oxygenation and prevent further complications. Hyperthermia, impaired transfer ability, and ineffective airway clearance are important concerns but addressing gas exchange takes precedence in this scenario.
