A client in the cardiac step-down unit requires suctioning for excess mucous secretions. The nurse should be most careful to monitor the client for which dysrhythmia during this procedure?

Correct Answer: A

Rationale: During suctioning, a vagal response can be triggered leading to bradycardia. It is crucial for the nurse to monitor for this potential dysrhythmia. Tachycardia (Choice B) is less likely during suctioning and is not the priority. Premature ventricular beats (Choice C) and heart block (Choice D) can occur but are less common compared to bradycardia in this situation.

Correct Answer: C

Rationale: The most crucial assessment during the preoperative period for a client scheduled for surgical repair of a sacular abdominal aortic aneurysm is the identification of peripheral pulses. This is essential because during surgery, the aorta will be clamped, potentially affecting blood circulation to the kidneys and lower extremities. Monitoring peripheral pulses helps assess circulation to the lower extremities, ensuring adequate perfusion. While assessing the client's anxiety level (choice A) is important, it is not as critical as monitoring peripheral pulses in this case. Evaluating exercise tolerance (choice B) is not typically recommended preoperatively for this specific condition. Assessing bowel sounds and activity (choice D) is also relevant but takes a lower priority compared to identifying peripheral pulses in this scenario.

Correct Answer: A

Rationale: Lasix should be administered over 1-2 minutes at approximately 1mL per minute to prevent hypotension. This slow administration helps to reduce the risk of adverse effects such as sudden drops in blood pressure. Choice B is incorrect because Lasix does not need to be hung IV piggyback, choice C is incorrect as Lasix administration does not require it to be mixed with normal saline only, and choice D is incorrect as Lasix does not have to be specifically administered through a venous access device (VAD) to prevent hypotension.

Correct Answer: B

Rationale: A persistent cough might be related to an adverse reaction to captopril (Capoten). Tinnitus (choice A) and diarrhea (choice D) are not commonly associated adverse reactions of captopril. Muscle weakness (choice C) might occur initially but is not considered a common adverse effect of captopril. Therefore, the correct answer is B, persistent cough, as it is a known adverse reaction to captopril.

Correct Answer: C

Rationale: The correct answer is a red, beefy tongue, which is characteristic of pernicious anemia due to the atrophy of the papillae on the tongue. This finding is known as glossitis. A red, beefy tongue is a classic sign of pernicious anemia. Choice A, weight loss of 10 pounds in 2 weeks, is non-specific and not a typical finding in pernicious anemia. Choice B, complaints of numbness and tingling in the extremities, are more indicative of peripheral neuropathy, a common symptom of vitamin B12 deficiency, which can be seen in pernicious anemia. Choice D, a hemoglobin level of 12.0 g/dL, falls within the normal range and does not specifically point towards pernicious anemia, which is characterized by low hemoglobin levels due to impaired absorption of vitamin B12.
