Correct Answer: C

Rationale: The correct answer is C: Teach the patient how to administer insulin. This action is crucial in promoting self-management and control of diabetes. By educating the patient on administering insulin, they can actively participate in their treatment plan. Monitoring blood sugar levels (choice A) is important but doesn't empower the patient to take direct action. Encouraging a diabetic meal plan (choice B) is beneficial but may not directly address the need for insulin administration. Teaching about the complications of diabetes (choice D) is essential but may not be as immediately impactful as teaching insulin administration for day-to-day management.

Correct Answer: B

Rationale: The correct course of action is to remove the jewelry and document the removal. While religious beliefs should be respected, ensuring patient safety during surgery is crucial. Securing the jewelry may not be sufficient to prevent any interference during the surgical procedure. Documenting the removal is important for legal and documentation purposes. Delaying the surgery or removing the jewelry with the family's permission may not be the best options as patient safety should be the top priority in this situation.

Correct Answer: B

Rationale: The correct answer is B: Providing wigs and other coping resources helps clients manage the emotional effects of chemotherapy-related hair loss. Encouraging the client to cut their hair short before chemotherapy (Choice A) is not necessary as hair loss may still occur. Assuring the client that hair loss will be minimal (Choice C) may provide false hope as hair loss is a common side effect of chemotherapy. Offering medication to reduce hair loss (Choice D) is not a typical approach as chemotherapy-related hair loss is often an expected side effect that cannot be entirely prevented with medication.

Correct Answer: A

Rationale: The correct answer is to encourage early ambulation and leg exercises. By promoting early ambulation and leg exercises, blood flow is enhanced, reducing the risk of venous thromboembolism (VTE) in postoperative patients. Choice B, applying compression stockings, helps prevent VTE but is not as effective as early ambulation and exercises. Choice C, administering anticoagulants, is important in VTE prevention but does not directly address improving circulation through physical activity. Choice D, elevating the patient's legs, may be beneficial for circulation in specific cases but is not as effective in preventing VTE as early ambulation and leg exercises.

Correct Answer: B

Rationale: When a health care provider orders a medication with a dosage significantly higher than usual, the nurse's initial action should be to question the provider and verify the dose. This is crucial to ensure patient safety and prevent medication errors. Administering the medication as ordered (Choice A) without clarification could potentially harm the patient if there was an error in the prescription. Administering half the dosage as a precaution (Choice C) is not a safe practice as it deviates from the prescribed order. Refusing to administer the medication without clarification (Choice D) is important, but the first step should be to seek clarification from the provider to prevent any unnecessary delays in patient care.
