NCLEX PN Practice Test Questions
Extract:
Question 1 of 5
A client is diagnosed as having secondary Cushing's syndrome. The nurse knows that the client has most likely been taking which medication?
Correct Answer: D
Rationale: Secondary Cushing's syndrome is often caused by long-term prednisone use, a corticosteroid mimicking cortisol excess. Estrogen, penicillin, or lovastatin do not cause this condition.
Question 2 of 5
The nurse is planning care for a client who must remain in bed for several weeks. Which action will do most to prevent the development of pressure ulcers?
Correct Answer: D
Rationale: Frequent position changes relieve pressure on bony prominences, preventing pressure ulcers. ROM, breathing, or footboards address other complications.
Question 3 of 5
An adult client is showing signs of developing hypovolemic shock. Which finding is most likely to be present?
Correct Answer: C
Rationale: Hypovolemic shock reduces circulating volume, decreasing renal perfusion and causing oliguria (decreased urine output). Blood pressure typically narrows, heart rate increases, and respiratory rate rises.
Question 4 of 5
When teaching parents about sickle cell disease, the nurse should tell them that their child's anemia is caused by
Correct Answer: B
Rationale: An imbalance between red cell destruction and production. Anemia results when the rate of red cell destruction exceeds the rate of production through stimulated erythropoiesis in bone marrow (red cell life span shortened from 120 days to 12-20 days).
Question 5 of 5
A client taking Zoloft (sertraline) tells the nurse that she has also been taking St. John's wort. The nurse should report this information to the doctor because:
Correct Answer: B
Rationale: St. John's wort can induce the metabolism of Zoloft, potentially reducing its effectiveness, so the doctor may need to adjust the dose. Answer A is incorrect as they do not have opposing effects. Answer C is incorrect as St. John's wort has pharmacological effects. Answer D is incorrect as increasing the dose may not be necessary.
