Correct Answer: B

Rationale: When a patient presents with confusion, the best initial action is to perform a neurological assessment. This assessment helps in identifying potential causes of confusion such as neurological issues, infections, metabolic abnormalities, or medication side effects. Administering IV fluids (Choice A) may be necessary based on assessment findings, but it is not the first step. Administering electrolytes (Choice C) would also depend on the assessment results. Preparing for a CT scan (Choice D) may be indicated later in the diagnostic process but is not the initial action when a patient presents with confusion.

Correct Answer: D

Rationale: The correct answer is D. Urinary output greater than fluid intake could indicate diabetes insipidus, a complication following hypophysectomy. Diabetes insipidus is characterized by excessive urination and extreme thirst due to inadequate levels of antidiuretic hormone (ADH). Options A, B, and C are all expected findings in the immediate postoperative period following a hypophysectomy. A Glasgow Coma Scale score of 15 indicates the highest level of consciousness, blood drainage on the initial dressing is a common finding after surgery, and dry mouth can be a side effect of anesthesia and surgical procedures.

Correct Answer: C

Rationale: The correct answer is C. Clients with type 1 diabetes should rotate injection sites within the same anatomical region to prevent lipodystrophy. Choice A is incorrect because blood glucose levels should be checked regularly, not only when feeling sick. Choice B is incorrect as injecting insulin in the same spot each time can lead to lipodystrophy. Choice D is incorrect as insulin injections are usually required based on meal schedules and blood glucose levels, not just when levels are above 200 mg/dL.

Correct Answer: A

Rationale: Methimazole is the correct answer. It is commonly used to treat hyperthyroidism by inhibiting the production of thyroid hormones. Levothyroxine, on the other hand, is a medication used to treat hypothyroidism by providing synthetic thyroid hormone. Propylthiouracil is another medication used to treat hyperthyroidism by blocking the production of thyroid hormones. Aspirin is not used to treat hyperthyroidism, but rather for pain relief and reducing inflammation.

Correct Answer: C

Rationale: The correct answer is C. A serum potassium level of 3.2 mEq/L indicates hypokalemia, a potential complication of furosemide therapy, and should be reported immediately. Hypokalemia can lead to serious cardiac dysrhythmias. Choices A, B, and D are important assessments but are not as critical as managing serum potassium levels in a client receiving furosemide for heart failure.
