Correct Answer: A

Rationale: The correct answer is to monitor blood glucose levels. When a patient is receiving insulin therapy, it is crucial to monitor blood glucose levels regularly to prevent hypoglycemia, a potential side effect of insulin therapy. Monitoring potassium, calcium, or sodium levels is important for different medical conditions or treatments and is not directly related to insulin therapy.

Correct Answer: C

Rationale: The correct answer is C because limiting saturated fat intake to 7% of daily calories is a crucial component of the dietary management for hypertension. This dietary modification helps reduce the risk of cardiovascular complications. Choices A, B, and D are incorrect. Choice A is incorrect because medication adherence should not be based on symptoms like dizziness. Choice B is inadequate as blood pressure monitoring should be more frequent, preferably daily, for effective management of hypertension. Choice D is incorrect because medication for hypertension should be taken consistently as prescribed, not just when symptoms occur.

Correct Answer: B

Rationale: The correct instruction when taking levothyroxine is to take it on an empty stomach. This enhances absorption and ensures the medication's effectiveness. Taking it with food or other substances, such as milk or antacids, can interfere with its absorption. Therefore, choices A, C, and D are incorrect.

Correct Answer: A

Rationale: Lipsmacking is a common sign of tardive dyskinesia, a long-term side effect of haloperidol. Tardive dyskinesia is characterized by repetitive, involuntary, purposeless movements such as lipsmacking, tongue protrusion, and facial grimacing. Agranulocytosis (choice B) is a potential side effect of antipsychotic medications but is not specifically associated with haloperidol. Clang association (choice C) is a form of disorganized speech seen in conditions like schizophrenia but is not a side effect of haloperidol. Alopecia (choice D) refers to hair loss and is not a common long-term side effect of haloperidol.

Correct Answer: C

Rationale: The correct answer is to monitor aPTT for a patient receiving heparin therapy. The activated partial thromboplastin time (aPTT) is used to assess and adjust heparin dosage to ensure the patient is within the therapeutic range for anticoagulation. Monitoring the aPTT helps in preventing both clotting and bleeding complications. Platelet count (Choice A) is important to monitor for patients receiving antiplatelet therapy, not heparin. PT/INR (Choice B) is typically monitored for patients on warfarin therapy, not heparin. Monitoring the complete blood count (CBC) (Choice D) is essential for various conditions but is not specific to monitoring heparin therapy.
