Correct Answer: B

Rationale: The correct answer is to monitor blood glucose levels before administration. This step is crucial to ensure the correct dose of insulin is administered based on the current blood glucose level. Choice A is incorrect as insulin usually needs to be stored in the refrigerator and has an expiration date. Choice C is incorrect because insulin can be short-acting, rapid-acting, intermediate-acting, or long-acting. Choice D is also incorrect as insulin can have side effects such as hypoglycemia if the dose is too high.

Correct Answer: C

Rationale: The correct answer is C. Omeprazole is a proton pump inhibitor that can mask symptoms of gastrointestinal bleeding; clients should be monitored for this. Choices A and B are incorrect because omeprazole is usually taken before meals, and while it is important to avoid NSAIDs if possible due to their effects on the stomach, it is not directly related to omeprazole use. Choice D is also incorrect as omeprazole is not typically associated with causing drowsiness.

Correct Answer: A

Rationale: The correct answer is A: Liver function tests. Atorvastatin, a medication commonly used to lower cholesterol levels, can potentially cause liver damage as a side effect. Monitoring liver function tests is essential to detect any abnormalities early. Choices B, C, and D are incorrect because atorvastatin is not known to directly impact potassium levels, blood glucose levels, or serum calcium levels. While these parameters may be monitored for other reasons, the priority when administering atorvastatin is to monitor liver function due to the risk of hepatotoxicity.

Correct Answer: A

Rationale: Correct Answer: A nurse should include monitoring for agranulocytosis when educating a patient about clozapine. Clozapine is known to cause agranulocytosis, a potentially life-threatening decrease in white blood cells. This adverse effect requires close monitoring to detect it early. Choices B, C, and D are incorrect because clozapine is not a first-line treatment for most conditions, it is more commonly associated with weight gain rather than weight loss, and it is known to have a risk for metabolic syndrome.

Correct Answer: A

Rationale: Corrected Rationale: Digitalis toxicity is a serious complication of digoxin therapy, particularly in older adults. Early symptoms include anorexia, nausea, and generalized weakness. Anorexia and weakness are common indicators of digitalis toxicity. Hyperactivity, hunger, tachycardia, increased urination, polyphagia, and polydipsia are not typical signs of digitalis toxicity. Monitoring for anorexia and weakness can help detect toxicity early and prevent life-threatening arrhythmias.
