Correct Answer: C

Rationale: The correct answer is C: Persistent cough. Lisinopril is an ACE inhibitor commonly associated with a persistent dry cough as a side effect. This cough is thought to result from increased bradykinin levels. Choices A, B, and D are incorrect. Hypokalemia is not a common side effect of lisinopril; in fact, it may lead to hyperkalemia. Hyperglycemia is not a typical side effect of lisinopril use. Tachycardia is also not a common side effect associated with ACE inhibitors like lisinopril.

Correct Answer: A

Rationale: Correct! Monitoring INR is essential in clients on anticoagulant therapy to ensure the blood's clotting time is within the therapeutic range, preventing further embolic events or excessive bleeding. Monitoring blood glucose levels (Choice B), blood pressure (Choice C), and temperature (Choice D) is important for various other conditions but is not directly related to anticoagulant therapy for a client with a history of pulmonary embolism.

Correct Answer: B

Rationale: The priority nursing action in this scenario is to perform an ECG. An ECG is crucial in confirming myocardial infarction promptly and guiding immediate treatment decisions. Administering oxygen as prescribed is important but not the priority over confirming the diagnosis. Obtaining a detailed health history is relevant but does not take precedence over immediate diagnostic confirmation. While monitoring vital signs regularly is essential, performing an ECG is the priority action in this scenario to guide timely management.

Correct Answer: A

Rationale: Administering morphine is a priority intervention during the acute phase of myocardial infarction (MI). Morphine not only provides pain relief but also reduces myocardial oxygen demand, which is crucial in this situation. Choice B is incorrect because isometric exercises can increase myocardial oxygen demand and are not recommended during the acute phase of MI. Choice C is incorrect as elevating the head of the bed, not keeping the client flat, is preferred to reduce workload on the heart. Choice D is incorrect because fluid intake should be encouraged unless contraindicated, as adequate hydration is essential for cardiac function.

Correct Answer: C

Rationale: Tingling around the mouth should be reported to the healthcare provider immediately as it may indicate hypocalcemia, a potential complication after thyroidectomy. Hoarseness of the voice is common postoperatively due to surgical manipulation, slight swelling at the incision site is a normal response, and a mild fever can be expected after surgery. However, tingling around the mouth suggests a potential calcium imbalance, which requires prompt attention to prevent serious complications.
