NCLEX RN Exam Review Answers
1. The clinic nurse reviews the record of an infant and notes that the primary health care provider (PHCP) has documented a diagnosis of suspected Hirschsprung's disease. The nurse reviews the assessment findings documented in the record, knowing that which sign most likely led the mother to seek health care for the infant?
- A. Diarrhea
- B. Projectile vomiting
- C. Regurgitation of feedings
- D. Constipation
Correct answer: C
Rationale: Hirschsprung's disease, also known as congenital aganglionosis or aganglionic megacolon, is characterized by the absence of ganglion cells in the rectum and other parts of the affected intestine. Clinical manifestations of Hirschsprung's disease include chronic constipation with pellet-like or ribbon-like foul-smelling stools, delayed or absent passage of meconium in the neonatal period, bowel obstruction (especially in the neonatal period), abdominal pain and distention, and failure to thrive. In the case of an infant with suspected Hirschsprung's disease, regurgitation of feedings is a sign that may have led the mother to seek healthcare. This symptom can be associated with the bowel dysfunction and obstruction seen in Hirschsprung's disease. Options A, B, and D are not typically associated with Hirschsprung's disease. Diarrhea is not a common symptom, projectile vomiting is not a typical presentation, and constipation, while a symptom of the disease, is not the sign that would most likely prompt a visit to seek healthcare in an infant suspected of having Hirschsprung's disease.
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. Which of the following is the most common type of malignant brain tumor in the United States?
- A. Meningioma
- B. Glioblastoma multiforme
- C. Acoustic neuroma
- D. Pituitary adenoma
Correct answer: B
Rationale: Glioblastoma multiforme is the most common malignant brain tumor in the United States, accounting for a significant portion of cases. It is known for its aggressive nature and poor prognosis. Surgical resection, followed by radiation and chemotherapy, is the standard treatment approach for glioblastoma multiforme. Meningioma, acoustic neuroma, and pituitary adenoma are also types of brain tumors but are not as common as glioblastoma multiforme in the United States.
4. During an assessment of a client with cardiomyopathy, the nurse finds that the systolic blood pressure has decreased from 145 to 110 mm Hg and the heart rate has risen from 72 to 96 beats per minute, and the client complains of periodic dizzy spells. The nurse instructs the client to:
- A. Increase fluids that are high in protein
- B. Restrict fluids
- C. Force fluids and reassess blood pressure
- D. Limit fluids to non-caffeine beverages
Correct answer: D
Rationale: In this scenario, the client with cardiomyopathy is exhibiting signs of orthostatic hypotension, which is characterized by a significant drop in systolic blood pressure (>15 mm Hg) and an increase in heart rate (>15%), along with dizziness. These symptoms suggest volume depletion, inadequate vasoconstrictor mechanisms, and autonomic insufficiency. The appropriate nursing intervention in this case is to force fluids and reassess blood pressure to address the underlying issue of volume depletion and improve hemodynamic stability. Choices A, B, and D are incorrect because increasing fluids high in protein, restricting fluids, or limiting fluids to non-caffeine beverages are not appropriate actions for a client experiencing orthostatic hypotension and signs of volume depletion.
5. Which of the following clients is most appropriate for receiving telemetry?
- A. A client with syncope potentially related to cardiac dysrhythmia
- B. A client with unstable angina
- C. A client with sinus rhythm and PVCs
- D. A client who had a myocardial infarction 6 hours ago
Correct answer: A
Rationale: Telemetry is used to monitor the cardiac rhythms of clients with potentially unstable conditions or those rhythms that affect activities. Clients with syncope potentially related to cardiac dysrhythmia require continuous monitoring to detect any potential life-threatening dysrhythmias. Unstable angina can be monitored in a telemetry unit, but syncope with potential cardiac causes takes precedence. Clients with sinus rhythm and PVCs may not necessitate telemetry unless there are further indications of instability. A client who had a myocardial infarction 6 hours ago is typically monitored in an intensive care unit rather than a telemetry unit.
