Correct Answer: A

Rationale: The correct answer is A. The nurse is responsible for providing a safe environment for the patient. In this situation, the nurse should follow up with the nursing assistive personnel (NAP) who turned off the handle faucet with bare hands to ensure infection control practices are maintained. This action is crucial to prevent the spread of infections in the hospital setting. Choice B is incorrect because the question is not specifically about handwashing procedures but about infection control practices. Choice C is incorrect as it does not address the potential risk of infection transmission. Choice D is incorrect as it is unrelated to the main concern of infection control in this scenario.

Correct Answer: A

Rationale: The most important instruction to provide when teaching a patient about self-administration of insulin is to rotate injection sites to prevent tissue damage. Rotating injection sites helps prevent lipodystrophy (tissue damage) and ensures proper insulin absorption. Option B is incorrect because the angle of insulin injection varies depending on the patient's body composition. Injecting at a 90-degree angle is not always necessary. Option C is not the most crucial instruction; while storing insulin in the refrigerator is important, it is not the priority when teaching self-administration. Option D is also important for maintaining consistency but is not as critical as rotating injection sites to prevent tissue damage.

Correct Answer: A

Rationale: The correct answer is A: 'Dangle the patient at the bedside.' When a patient has been in bed for an extended period and needs to be ambulated, it is essential to dangle the patient at the bedside first. Dangling involves helping the patient sit on the edge of the bed with their legs over the side before standing up. This action helps prevent orthostatic hypotension, a sudden drop in blood pressure when moving from lying down to standing up, which can lead to dizziness or fainting. Encouraging isometric exercises (choice B) or suggesting a high-calcium diet (choice C) are not the first actions to take before ambulating a patient. Maintaining a narrow base of support (choice D) is related to assisting with ambulation but is not the initial step that should be taken.

Correct Answer: B

Rationale: The correct answer is to measure the calf circumference of both legs when assessing a patient for possible DVT. An increase in calf circumference in one leg can indicate the presence of a DVT. Option A is incorrect because dorsiflexing the foot and checking for pain are not primary assessments for DVT. Option C is incorrect as redness of the skin may not always be present in cases of DVT. Option D is incorrect as performing a Doppler ultrasound scan is usually done after clinical assessment and to confirm the diagnosis, not as the initial priority assessment.

Correct Answer: A

Rationale: The correct answer is A: 'Assist the patient with comfort measures.' When a patient is experiencing impaired physical mobility due to pain, the priority action is to provide comfort measures to help manage the pain. By addressing the pain, the patient may then feel more comfortable moving and engaging in mobility exercises. Option B, 'Keep the patient as mobile as possible,' could exacerbate the pain and should not be the initial action. While encouraging range of motion (ROM) exercises (Option C) and self-care (Option D) are important aspects of care, addressing pain and comfort should take precedence in this scenario.
