HESI RN
Evolve HESI Medical Surgical Practice Exam
1. A nurse contacts the healthcare provider after reviewing a client’s laboratory results and noting a blood urea nitrogen (BUN) of 35 mg/dL and a creatinine of 1.0 mg/dL. For which action should the nurse recommend a prescription?
- A. Intravenous fluids
- B. Hemodialysis
- C. Fluid restriction
- D. Urine culture and sensitivity
Correct answer: A
Rationale: The normal range for BUN is 10 to 20 mg/dL, and for creatinine, it is 0.6 to 1.2 mg/dL in males and 0.5 to 1.1 mg/dL in females. Creatinine is a more specific marker for kidney function compared to BUN. In this case, the client's creatinine level is within the normal range, indicating a non-renal cause for the elevated BUN. Dehydration is a common cause of increased BUN, so the appropriate action would be to recommend intravenous fluids to address the dehydration. Fluid restriction is not indicated as the client needs hydration. Hemodialysis is not appropriate for dehydration and is typically reserved for renal failure. The laboratory results do not suggest an infection, making a urine culture and sensitivity unnecessary in this scenario.
2. After a myocardial infarction, why is the hospitalized client taught to move the legs while resting in bed?
- A. Prepare the client for ambulation.
- B. Promote urinary and intestinal elimination.
- C. Prevent thrombophlebitis and blood clot formation.
- D. Decrease the likelihood of pressure ulcer formation.
Correct answer: C
Rationale: The correct answer is C. Moving the legs helps prevent thrombophlebitis and blood clot formation by promoting venous return in clients on bed rest. This prevents stasis and clot formation in the lower extremities. Choices A, B, and D are incorrect because the primary goal of moving the legs is to prevent thrombophlebitis and blood clot formation, rather than preparing for ambulation, promoting elimination, or decreasing pressure ulcer formation. Ambulation preparation involves different exercises, urinary and intestinal elimination are not directly related to leg movements, and pressure ulcer prevention is more related to repositioning and skin care.
3. A newborn's parents tell the nurse that their baby is already trying to walk. How should the nurse respond?
- A. Encourage the parents to report this to the healthcare provider.
- B. Acknowledge the parents' observation.
- C. Schedule the newborn for further neurological testing.
- D. Explain the newborn’s normal stepping reflex.
Correct answer: D
Rationale: When parents report that their newborn is trying to walk, the nurse should understand that newborns exhibit a stepping reflex, which is a normal developmental response. Explaining this reflex to the parents helps them understand that it is a typical behavior seen in newborns rather than true attempts to walk. Encouraging the parents to report this to the healthcare provider (Choice A) may cause unnecessary concern since the stepping reflex is a normal part of newborn development. Acknowledging the parents' observation (Choice B) is a good communication strategy but providing education on the normal reflex is essential. Scheduling the newborn for further neurological testing (Choice C) is not indicated in this scenario as the stepping reflex is a typical finding in newborns.
4. The instructor is teaching a prenatal class about the importance of folic acid. Which outcome indicates that the teaching was effective?
- A. participants can list foods high in folic acid
- B. participants plan to take folic acid supplements daily
- C. participants understand the risks of folic acid deficiency
- D. participants demonstrate how to read nutrition labels for folic acid content
Correct answer: B
Rationale: The correct answer is B because planning to take folic acid supplements daily is a proactive step towards preventing folic acid deficiency and reducing the risk of neural tube defects in pregnancy. While choice A is important for dietary knowledge, the direct action of taking supplements is more effective. Choice C, understanding the risks, is good but does not ensure action. Choice D, reading nutrition labels, is helpful but doesn't guarantee intake of folic acid.
5. A client with Addison's disease is receiving corticosteroid therapy. The nurse should monitor the client for which of the following potential side effects?
- A. Hypoglycemia
- B. Hypertension
- C. Weight loss
- D. Hyperkalemia
Correct answer: B
Rationale: When a client with Addison's disease is receiving corticosteroid therapy, the nurse should monitor for hypertension as a potential side effect. Corticosteroids can lead to hypertension by causing fluid retention and increased blood volume. Hypoglycemia (Choice A) is not a common side effect of corticosteroid therapy; instead, hyperglycemia is more likely. Weight loss (Choice C) is not a typical side effect of corticosteroid therapy; in fact, weight gain is more common due to fluid retention and increased appetite. Hyperkalemia (Choice D) is a potential side effect of Addison's disease itself due to adrenal insufficiency, but it is not directly caused by corticosteroid therapy.
