HESI RN
HESI Medical Surgical Exam
1. A client with type 1 diabetes mellitus has influenza. The nurse should instruct the client to:
- A. Increase the frequency of self-monitoring (blood glucose testing).
- B. Reduce food intake to alleviate nausea.
- C. Discontinue the insulin dose if unable to eat.
- D. Take the normal dose of insulin.
Correct answer: A
Rationale: During illness, individuals with type 1 diabetes mellitus may experience increased insulin requirements due to factors such as stress and the release of counterregulatory hormones. Increasing the frequency of self-monitoring, as stated in choice A, is crucial to closely monitor and adjust insulin doses as needed. Choice B, reducing food intake to alleviate nausea, is incorrect as it may lead to hypoglycemia and does not address the increased insulin needs during illness. Choice C, discontinuing the insulin dose if unable to eat, is dangerous as it can result in uncontrolled hyperglycemia. Choice D, taking the normal dose of insulin, may not be sufficient during illness when insulin requirements are likely elevated.
2. A client is admitted to the postpartum unit and tells the nurse she had rheumatic fever as a child, which resulted in some 'heart damage'. The nurse knows that this client is at particular risk for developing heart failure during the immediate postpartum period. Based on the client's history, which nursing problem has the highest priority?
- A. Nausea and vomiting.
- B. Risk for infection.
- C. Sleep deprivation.
- D. Fluid volume excess.
Correct answer: D
Rationale: Fluid volume excess is a priority concern in this client, as heart damage from rheumatic fever can impair the heart's ability to manage increased blood volume postpartum, leading to potential heart failure. Monitoring and managing fluid volume status are crucial to prevent complications in this high-risk client. Choices A, B, and C are not the highest priority in this situation. Nausea and vomiting, risk for infection, and sleep deprivation are important but do not pose an immediate threat to the client's physiologic stability compared to the risk of heart failure due to fluid volume excess.
3. A client with Addison's disease becomes confused and weak. What is the nurse's first action?
- A. Administer a dose of hydrocortisone immediately.
- B. Check the client’s electrolyte levels.
- C. Administer a dose of normal saline.
- D. Measure the client’s blood pressure in both arms.
Correct answer: A
Rationale: The correct answer is to administer a dose of hydrocortisone immediately. In Addison's disease, confusion and weakness can be signs of an adrenal crisis. Administering hydrocortisone promptly is crucial to prevent further deterioration. Checking electrolyte levels (Choice B) is important but not the first action in managing an acute adrenal crisis. Administering normal saline (Choice C) is not the priority in this situation. Measuring blood pressure in both arms (Choice D) is not the initial action needed to address the client's confusion and weakness in Addison's disease.
4. The clinic nurse is performing an admission assessment on a client. The nurse notes that the client is taking azelaic acid (Azelex). Because of the medication prescription, the nurse would suspect that the client is being treated for:
- A. Acne
- B. Eczema
- C. Hair loss
- D. Herpes simplex
Correct answer: A
Rationale: Azelaic acid (Azelex) is a topical medication used to treat mild to moderate acne. It works by suppressing the growth of Propionibacterium acnes and decreasing the proliferation of keratinocytes in the skin. Therefore, if a client is prescribed azelaic acid, the nurse would suspect that the client is being treated for acne.
5. The nurse is conducting an admission assessment of an 11-month-old infant with CHF who is scheduled for repair of restenosis of coarction of the aorta that was repaired 4 days after birth. Findings include blood pressure higher in the arms than the lower extremities, pounding brachial pulses, and slightly palpable femoral pulses. What pathophysiologic mechanisms support these findings?
- A. The aortic semilunar valve obstructs blood flow into the systemic circulation
- B. The lumen of the aorta reduces the volume of the blood flow to the lower extremities
- C. The pulmonic valve prevents adequate blood volume into the pulmonary circulation
- D. An opening in the atrial septum causes a murmur due to a turbulent left-to-right shunt
Correct answer: B
Rationale: The correct answer is B. Coarctation of the aorta causes narrowing of the aorta, reducing blood flow to the lower extremities. This narrowing results in higher blood pressure in the arms compared to the lower extremities, along with stronger brachial pulses and slightly palpable femoral pulses. Choices A, C, and D are incorrect because they do not align with the pathophysiological mechanism of coarctation of the aorta, which specifically leads to reduced blood flow to the lower extremities.
