Correct Answer: A

Rationale: The correct answer is A. Providing oral care every 4 hours helps prevent ventilator-associated pneumonia by reducing the buildup of bacteria in the mouth that can be aspirated into the lungs. Repositioning the patient every 2 hours is important for preventing pressure ulcers but is not directly related to preventing VAP. Suctioning the patient as needed is essential for maintaining airway patency but does not specifically prevent VAP. Administering antibiotics as prescribed is a treatment for infections but does not prevent VAP.

Correct Answer: C

Rationale: When a patient is immobile, the nurse should assess for psychosocial aspects, including a loss of hope and increased risk of depression. While issues like weight loss (choice A), loss of bone mass (choice B), and loss of strength (choice D) can also occur due to immobility, the primary concern in this scenario is the patient's mental and emotional well-being, making 'Loss of hope' the correct answer.

Correct Answer: B

Rationale: The correct answer is B. Proper documentation should include objective observations and detailed notes to ensure continuity of care. Choice A is incorrect because incomplete entries can lead to gaps in information and compromise patient care. Choice C is not completely accurate as corrections should be made in a manner that does not obscure the original entry but does not necessarily require a signature. Choice D is incorrect as entries should ideally be corrected by the original author to maintain accountability and accuracy.

Correct Answer: B

Rationale: The correct answer is B because the lateral position means lying on the side with body weight on the dependent hip and shoulder. Choice A is incorrect as 'semiprone' means lying on the abdomen with one leg flexed. Choice C is incorrect as 'prone' means lying face down. Choice D is incorrect as 'supine' means lying on the back.

Correct Answer: B

Rationale: When a client with a history of substance abuse requests pain medication, the nurse should first assess the patient's pain level. It is important to determine the nature and intensity of the pain before administering any medication to ensure appropriate pain management. Administering medication without assessing the pain level can lead to unnecessary drug administration or inadequate pain relief. Administering a placebo would be unethical and ineffective. Refusing to give any medication without proper assessment can compromise the client's comfort and recovery. Therefore, the correct approach is to assess the patient's pain level first before deciding on the most suitable pain management intervention.
