Correct Answer: A

Rationale: The correct answer is A. A reduction in the need for analgesic medication indicates that guided imagery is effective in managing the patient's pain. Choices B, C, and D do not directly measure the effectiveness of guided imagery. A patient rating pain as 6 on a scale of 0 to 10, asking for pain medication once, or having stoic facial expressions may not necessarily reflect the impact of guided imagery on pain management.

Correct Answer: B

Rationale: During chemotherapy, hair loss is a common side effect. Offering resources for wigs and head coverings can help the client cope with this change in appearance, maintain self-esteem, and feel more comfortable during the process. Encouraging the client to cut their hair short does not address the emotional impact of hair loss and may not be the client's preference. Assuring the client that hair loss will be minimal may provide false hope as significant hair loss is a common occurrence. Ignoring the client's concerns is not appropriate and goes against the principles of providing holistic and compassionate care.

Correct Answer: B

Rationale: During a fire emergency, it is crucial to close all doors to contain smoke and fire, helping to protect the patients. This action can prevent the spread of fire and smoke to the area where patients are located. Identifying evacuation routes is also important for a timely and orderly evacuation if necessary. Waiting for the fire department to arrive before taking action (Choice A) can waste valuable time and put patients at risk. Moving bedridden patients in their beds (Choice D) can be dangerous during a fire and should be avoided as it can expose patients and staff to more risks.

Correct Answer: B

Rationale: In this scenario, with no DNR order in place and the client not breathing, the nurse should initiate CPR and call for emergency assistance. Option A is incorrect as immediate action is required in the absence of breathing. Option C is incorrect as the nurse should act promptly to provide life-saving measures. Option D is incorrect because the nurse's primary duty is to provide care in the absence of a directive preventing intervention.

Correct Answer: A

Rationale: Administering insulin is the priority intervention for a patient admitted with high blood sugar levels because it helps lower the blood sugar levels effectively and rapidly. Insulin is a crucial medication for managing hyperglycemia in diabetes. Encouraging exercise (choice B) can be beneficial in the long term for managing blood sugar levels but is not the most immediate priority. While staying hydrated (choice C) is important, it is not the priority intervention when dealing with high blood sugar levels. Providing a low-sugar diet (choice D) is essential for long-term diabetes management but is not the immediate action needed to address high blood sugar levels in an admitted patient.
