A nurse is assisting with the preparation of a client who is scheduled for a paracentesis. In which of the following positions should the nurse place the client during the procedure?

Choice A: This is incorrect because applying lotion between the toes can create a moist environment that promotes fungal growth and infection. The client should apply lotion to the feet but avoid the areas between the toes.

Choice B: This is incorrect because wearing open-toe shoes can expose the feet to injury and infection. The client should wear well-fitting, closed-toe shoes that protect the feet and prevent pressure ulcers.

Choice C: This is correct because wearing cotton socks can help keep the feet dry and prevent fungal infections. Cotton socks also provide cushioning and reduce friction.

Choice D: This is incorrect because rounding the corners of the toenails can cause ingrown nails, which can lead to infection and ulceration. The client should trim the toenails straight across and file any sharp edges.

Choice A reason: BUN or blood urea nitrogen 30 mg/dL is above the normal range of 10 to 20 mg/dL and indicates renal impairment or dehydration, which can be caused by contrast dye used during coronary angiography or blood loss during or after the procedure. The nurse should report this value to the provider and monitor the client for signs of acute kidney injury, such as oliguria, edema, or electrolyte imbalances.

Choice B reason: Sinus rhythm 95/min on a cardiac monitor is within the normal range of 60 to 100/min and does not indicate any cardiac arrhythmia or ischemia.

Choice C reason: Respiratory rate 12/min is within the normal range of 12 to 20/min and does not indicate any respiratory distress or hypoxia.

Choice D reason: PTT or partial thromboplastin time 25 seconds is within the normal range of 25 to 35 seconds and does not indicate any bleeding disorder or anticoagulant therapy.
