Correct Answer: A

Rationale: The correct answer is A because advancing the walker too far ahead increases the risk of falls, indicating a need for further teaching. Choice B is correct as using the walker to assist in standing is a proper use. Choice C is correct as maintaining balance while using the walker shows proper technique. Choice D is incorrect as walking with the back hunched over is a posture issue, not directly related to walker use.

Correct Answer: B

Rationale: Maintaining eye contact and actively listening to the patient is crucial in effective communication as it helps build rapport, shows empathy, and ensures that the patient feels heard and understood. Providing written information can be helpful, but the direct interaction is essential for effective communication. Using medical jargon may confuse the patient instead of clarifying their condition. Speaking hurriedly can make the patient feel rushed and not valued, hindering effective communication.

Correct Answer: A

Rationale: In the context of restraining a patient, it is crucial for the health care provider to specify the type and location of the restraint in the order to ensure the safety and well-being of the patient. This information helps guide the nursing staff in the safe application of restraints. Renewing orders every 24 hours ensures that the need for restraints is continually assessed, promoting patient safety. Performing a face-to-face assessment before ordering restraints allows for a thorough evaluation of the patient's condition and the necessity of using restraints. Ordering restraints PRN (as needed) is not appropriate for safe care as it lacks specificity and may lead to inconsistent application and monitoring.

Correct Answer: A

Rationale: The correct answer is to administer nitroglycerin as prescribed. Nitroglycerin helps relieve chest pain by dilating blood vessels and improving blood flow, addressing the immediate concern of chest pain. Encouraging deep breaths may not be appropriate for chest pain, monitoring blood pressure, although important, is not the priority when the patient is experiencing chest pain, and while resting in a comfortable position is beneficial, administering nitroglycerin is the priority intervention to address the chest pain.

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.
