HESI Medical Surgical Practice Exam

Correct Answer: B

Rationale: During the acute phase of myocardial infarction, it is recommended to provide small, easily digested meals for the client. This type of diet is better tolerated as it reduces the workload on the heart, allowing for easier digestion and absorption of nutrients. Choice A, 'Liquids as desired,' may not provide adequate nutrition and may not be well-balanced. Choice C, 'Three regular meals per day,' may be too heavy for the client's weakened condition. Choice D, 'Nothing by mouth,' is not appropriate as the client still requires essential nutrients for recovery.

Correct Answer: B

Rationale: In a client presenting with possible myocardial infarction who is receiving oxygen therapy and cardiac monitoring, the next priority action is to establish IV access by starting an IV infusion. This allows for prompt administration of medications and fluids as needed in the management of acute coronary syndromes. Calling the physician (Choice A) may be necessary but is not the immediate next step. Obtaining a portable chest radiograph (Choice C) may help in further assessment but is not as crucial as establishing IV access. Drawing blood for laboratory studies (Choice D) is important for diagnostic purposes but is not as urgent compared to starting an IV infusion in the setting of a potential myocardial infarction.

Correct Answer: D

Rationale: The correct answer is D, 1 AM, while sleeping. Isophane insulin suspension NPH (Humulin N) peaks around 6-8 hours after administration, which increases the risk of hypoglycemia during the night. Choice A, 11 AM, shortly before lunch, is incorrect because the peak effect of NPH insulin occurs much later. Choice B, 1 PM, shortly after lunch, is incorrect as it is too early for the peak effect of NPH insulin. Choice C, 6 PM, shortly after dinner, is also incorrect because the peak risk of hypoglycemia with NPH insulin occurs later in the night.

Correct Answer: C

Rationale: The abdomen is the most appropriate site for insulin absorption in a client who jogs. When a client is involved in physical activity like jogging, the abdomen is preferred as it provides more consistent absorption compared to the arms or legs, which can have altered absorption rates due to increased blood flow during exercise. The iliac crest is not a common site for insulin injections and may not provide optimal absorption rates compared to the abdomen.

Correct Answer: C

Rationale: Encouraging the client to take slow, deep breaths is an effective way for the nurse to help the client manage anxiety during the bone marrow aspiration and biopsy procedure. Slow, deep breathing can promote relaxation and help reduce anxiety levels. Choice A, allowing the client's family to stay for emotional support, may provide comfort but does not address a direct intervention to help manage anxiety. Choice B, staying with the client silently, may not actively help the client address their anxiety. Choice D, allowing the client to express feelings, is important but may not directly address anxiety management during the procedure.
