NCLEX RN Practice Questions Quizlet
1. 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.
2. 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.
3. The nurse is caring for a patient who has recently had a successful catheter ablation. Which assessment finding demonstrates a successful outcome of this procedure?
- A. The patient is free of electrolyte imbalances
- B. The patient's WBC count is within normal limits
- C. The patient's EKG reading is regular
- D. The patient's urine output is 45 mL/hour
Correct answer: C
Rationale: A successful outcome of a catheter ablation procedure for arrhythmias, particularly SVT, is indicated by a regular EKG reading. Catheter ablation involves the use of radiofrequency energy to destroy the conduction fiber in the heart responsible for the arrhythmia. This destruction helps in preventing further episodes of arrhythmia. While choices A, B, and D are important assessments in patient care, they are not specific indicators of the success of a catheter ablation procedure. Electrolyte imbalances, WBC count, and urine output can be affected by various factors and are not directly related to the effectiveness of a catheter ablation in treating arrhythmias.
4. A client has just been diagnosed with active tuberculosis. Which of the following nursing interventions should the nurse perform to prevent transmission to others?
- A. Begin drug therapy within 72 hours of diagnosis
- B. Place the client in a positive-pressure room
- C. Initiate standard precautions
- D. Place the client in a negative-pressure room
Correct answer: D
Rationale: A client diagnosed with active tuberculosis should be placed in isolation in a negative-pressure room to prevent transmission of infection to others. Placing the client in a negative-pressure room ensures that air is exhausted to the outside and received from surrounding areas, preventing tuberculin particles from traveling through the ventilation system and infecting others. Initiating standard precautions, as mentioned in choice C, is essential for infection control but is not specific to preventing transmission in the case of tuberculosis. Beginning drug therapy within 72 hours of diagnosis, as in choice A, is crucial for the treatment of tuberculosis but does not directly address preventing transmission. Placing the client in a positive-pressure room, as in choice B, is incorrect as positive-pressure rooms are used for clients with compromised immune systems to prevent outside pathogens from entering the room, which is not suitable for a client with active tuberculosis.
5. An 85-year-old client is diagnosed with hypernatremia due to lack of fluid intake and dehydration. The nurse knows that symptoms of hypernatremia include:
- A. Lack of thirst
- B. Pale skin
- C. Hypertension
- D. Swollen tongue
Correct answer: D
Rationale: Hypernatremia among elderly clients can result from dehydration and insufficient fluid intake, leading to sodium levels above 145 mEq/L. Common symptoms of hypernatremia include mental status changes, a thick or swollen tongue, excessive thirst, and flushed skin. Choice A, 'Lack of thirst,' is incorrect as hypernatremia typically presents with excessive thirst. Choice B, 'Pale skin,' is not a typical symptom of hypernatremia. Choice C, 'Hypertension,' is not a direct symptom of hypernatremia and is more commonly associated with other conditions like hypertension itself.
