Correct Answer: B

Rationale: When obtaining blood pressure in the lower extremities, the popliteal pulse should be auscultated when the blood pressure cuff is applied around the thigh. The nurse should intervene when the UAP is auscultating the popliteal pulse with the cuff on the lower leg because this is incorrect placement. Option A, wrapping the cuff around the girth of the leg, ensures an accurate assessment. Option C, placing the client in a prone position, provides the best access to the artery. The systolic pressure in the popliteal artery is typically 10 to 40 mm Hg higher than in the brachial artery, so a systolic reading 20 mm Hg higher than the blood pressure in the client's arm is within the expected range and does not require intervention.

Correct Answer: A

Rationale: Implementing suicide precautions is the most critical intervention in this scenario as it directly addresses the patient's safety and the prevention of self-harm. The patient's significant weight loss, chronic low self-esteem, suicide plan, and recent initiation of an antidepressant medication indicate a high risk of self-harm. Suicide precautions involve close monitoring, removing harmful objects, and ensuring a safe environment to prevent the patient from acting on suicidal thoughts. While offering high-calorie snacks and fluids, assisting the patient in identifying personal strengths, and observing for therapeutic effects of the antidepressant are important aspects of care, they do not directly address the immediate risk of self-harm that implementing suicide precautions does.

Correct Answer: D

Rationale: The best nursing action is to discuss the client another time to ensure confidentiality. It is important to maintain the privacy of the client's information, so discussing sensitive topics like depression in a public area where conversations can be overheard is not appropriate. While options A, B, and C may seem like ways to protect the client's identity, they do not guarantee confidentiality since details like gender or age can still lead to identification. Therefore, the nurse should prioritize privacy and confidentiality by finding a more suitable time and location to have a private discussion about the client's concerns.

Correct Answer: D

Rationale: When a postoperative client's respiratory rate increases, it is essential to determine the underlying cause. Pain, anxiety, and fluid accumulation in the lungs can lead to tachypnea (increased respiratory rate). Therefore, the priority intervention is to assess if pain is the contributing factor. Encouraging increased ambulation may worsen oxygen desaturation in a client with a rising respiratory rate. Offering a high-carbohydrate snack is not indicated as it can increase carbon metabolism; instead, consider providing an alternative energy source like Pulmocare liquid supplement. Forcing fluids may exacerbate respiratory congestion in a client with a compromised cardiopulmonary system, potentially leading to fluid overload. Therefore, determining the role of pain in tachypnea is crucial for appropriate management.

Correct Answer: C

Rationale: The correct answer is 'Cranberry juice stops pathogens' adherence to the bladder.' Cranberry juice maintains urinary tract health by reducing the adherence of Escherichia coli bacteria to cells within the bladder. This helps prevent UTIs. Options A, B, and D are incorrect because orange juice with vitamin C, apple juice for urine acidification, and grapefruit juice for antibiotic absorption do not have the same proven effectiveness in preventing UTIs as cranberry juice does.
