HESI RN
HESI Medical Surgical Practice Exam
1. The client with type 1 diabetes mellitus is taught to take isophane insulin suspension NPH (Humulin N) at 5 PM each day. The client should be instructed that the greatest risk of hypoglycemia will occur at about what time?
- A. 11 AM, shortly before lunch.
- B. 1 PM, shortly after lunch.
- C. 6 PM, shortly after dinner.
- D. 1 AM, while sleeping.
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.
2. A client with a history of adrenal insufficiency is admitted with acute adrenal crisis. The client complains of nausea and joint pain, vital signs show a temperature of 102°F, heart rate of 138, and blood pressure of 80/60. Which intervention should the nurse implement first?
- A. Obtain an analgesic prescription.
- B. Infuse an intravenous fluid bolus.
- C. Administer PRN oral antipyretic.
- D. Cover the client with a cooling blanket.
Correct answer: B
Rationale: In acute adrenal crisis, the priority intervention is to infuse an intravenous fluid bolus to address the hypotension (blood pressure of 80/60) and help stabilize the client's condition. Adequate fluid volume is crucial in managing adrenal insufficiency crisis. Options A, C, and D do not directly address the hypotension and fluid volume depletion that are critical in this situation. Analgesics, antipyretics, and cooling blankets may be considered later, but the immediate focus should be on fluid resuscitation.
3. A client with a history of chronic kidney disease (CKD) is admitted with hyperkalemia. Which clinical finding is most concerning?
- A. Peaked T waves on the ECG
- B. Bradycardia
- C. Muscle weakness
- D. Decreased deep tendon reflexes
Correct answer: A
Rationale: Peaked T waves on the ECG are the most concerning finding in a client with hyperkalemia. Hyperkalemia can lead to serious cardiac complications, including arrhythmias and cardiac arrest. Peaked T waves are a classic ECG finding associated with hyperkalemia and indicate the need for immediate intervention. Bradycardia, muscle weakness, and decreased deep tendon reflexes can also be seen in hyperkalemia, but the presence of peaked T waves signifies a higher risk of cardiac events, making it the most concerning finding in this scenario.
4. A client is recovering from a hip replacement surgery. What is the priority nursing intervention to prevent complications?
- A. Encourage bed rest to prevent strain on the hip
- B. Assist the client with early ambulation
- C. Provide continuous passive motion therapy
- D. Administer pain medication before activity
Correct answer: B
Rationale: The correct answer is B: Assist the client with early ambulation. Early ambulation is a key intervention to prevent complications like deep vein thrombosis (DVT) and promote circulation after hip replacement surgery. It also helps with overall recovery and reduces the risk of complications related to immobility, such as muscle atrophy and pressure ulcers. Choice A is incorrect as bed rest should be avoided to prevent complications associated with immobility. Choice C, continuous passive motion therapy, is not the priority intervention immediately post-hip replacement surgery. Choice D, administering pain medication before activity, is important but not the priority intervention to prevent complications in this case.
5. A community health nurse is developing a program to increase physical activity among adults in the community. Which intervention is most likely to be successful?
- A. distributing flyers about the benefits of exercise
- B. organizing free community exercise classes
- C. partnering with local gyms to offer discounts
- D. hosting a health fair with information booths
Correct answer: B
Rationale: Organizing free community exercise classes is the most likely successful intervention as it provides a structured and accessible opportunity for adults to engage in physical activity. This choice directly offers a practical solution by providing a regular and organized setting for individuals to participate in physical activity. Distributing flyers about the benefits of exercise, while informative, may not lead to actual participation. Partnering with local gyms to offer discounts relies on individuals taking the initiative to sign up for gym memberships, which may not be feasible for everyone. Hosting a health fair with information booths is informative but may not directly address the need for increased physical activity among adults in the community.
