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: 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.

Correct Answer: B

Rationale: In a disaster situation like a building collapse, the nurse should attend to the victim with a partial amputation of a leg who is bleeding profusely first. This victim is at immediate risk of severe blood loss, which can be life-threatening. It is crucial to address life-threatening injuries like severe bleeding before attending to other less urgent cases. The victim with the amputation requires immediate intervention to control bleeding and stabilize their condition. Victims who are already deceased or have less urgent injuries can be attended to after addressing the critical cases.

Correct Answer: B

Rationale: Correctly positioning a patient to reduce the risk of pressure ulcers involves using pillows to support bony prominences. This helps to relieve pressure from vulnerable areas and prevent the development of pressure ulcers. Choice A is incorrect because keeping a patient in the supine position for extended periods can increase the risk of pressure ulcers. Choice C is incorrect as turning the patient every 2 hours, rather than every 4 hours, is recommended to prevent pressure ulcers. Choice D is not the best option mentioned for positioning a patient to reduce pressure ulcer risk; although alternating pressure mattresses can be beneficial, using pillows for support is a more direct and commonly used method.

Correct Answer: B

Rationale: Emptying the colostomy bag when it is half full is the most important nursing action when caring for a patient with a colostomy. This practice helps prevent leakage, reduces the risk of skin irritation, and promotes patient comfort. Monitoring for signs of infection (Choice A) is essential but not as crucial as maintaining proper colostomy care. Encouraging the patient to eat smaller, more frequent meals (Choice C) can be beneficial for colostomy patients but is not as critical as ensuring timely emptying of the colostomy bag. Applying a skin barrier to prevent irritation (Choice D) is important, but ensuring timely emptying of the colostomy bag takes precedence in preventing complications associated with a colostomy.
