HESI RN CAT Exit Exam 1

Correct Answer: A

Rationale: To calculate the infusion rate, we first need to determine the frequency of contractions per hour. If contractions are occurring every 2 to 3 minutes, this corresponds to 20 to 30 contractions in an hour (60 minutes). The average is 25 contractions in an hour. The pump should be infusing 1 ml for each contraction, so the infusion rate should be 25 ml/hr. Therefore, the correct answer is 42 ml/hr. Choices B, C, and D are incorrect as they do not align with the calculation based on the given data.

Correct Answer: C

Rationale: The correct answer is C. Clients in renal failure are at high risk for hypomagnesemia due to their impaired kidney function. Renal failure can lead to decreased excretion of magnesium, resulting in its buildup in the body and potential hypomagnesemia. This client requires careful nursing assessment for signs and symptoms of hypomagnesemia to prevent complications. Choices A, B, and D are not as directly associated with renal failure and its impact on magnesium levels. Intractable vomiting, hyperparathyroidism, and excessive consumption of simple carbohydrates may have other health implications but are not as strongly linked to hypomagnesemia as renal failure.

Correct Answer: B

Rationale: The correct action for the nurse to implement first is to elevate the head of the bed. Elevating the head of the bed helps prevent aspiration in clients with swallowing difficulties by reducing the risk of food or fluids entering the airway. While obtaining a speech therapy consult (Choice A) is important, the immediate priority is to ensure the client's safety by positioning them properly. Checking the client's lung sounds (Choice C) and implementing aspiration precautions (Choice D) are also essential steps but should follow the immediate intervention of elevating the head of the bed to prevent aspiration.

Correct Answer: C

Rationale: The correct answer is C, complaints of shortness of breath on exertion. This symptom is indicative of heart failure, a common cardiac complication of arterial hypertension. Shortness of breath on exertion is often due to the heart's inability to pump effectively, leading to fluid buildup in the lungs. Choices A, B, and D are incorrect because complaints of an occipital headache, a palpable dorsal pedis pulse bilaterally, and a blood pressure of 160/90 do not specifically indicate a cardiac complication in a client with arterial hypertension.

Correct Answer: B

Rationale: The correct nursing diagnosis for this client is 'Impaired skin integrity related to altered circulation and pressure.' The client's Stage II pressure ulcer on the left hip is a clear indication of impaired skin integrity resulting from altered circulation and pressure due to immobility. Choice A is incorrect because the client already has a pressure ulcer, indicating an actual impairment rather than a risk. Choice C is incorrect as ineffective tissue perfusion is not the primary issue in this case. Choice D is incorrect as it focuses solely on the paralysis and not the actual skin integrity issue.
