Correct Answer: A

Rationale: Establishing rapport with the client is essential in postoperative care to create a trusting relationship, decrease embarrassment, and improve the client's comfort during assessments. Choice B is incorrect because the lithotomy position is not typically recommended post-hemorrhoidectomy. Choice C is incorrect because milking the tube inserted during surgery is not a standard practice after a hemorrhoidectomy. Choice D is incorrect as digitally dilating the rectal sphincter can cause harm and is not a part of routine post-hemorrhoidectomy care.

Correct Answer: A

Rationale: Hepatic encephalopathy is caused by the buildup of ammonia in the body. Ammonia, a byproduct of protein metabolism, normally gets converted to urea in the liver for excretion. However, in liver dysfunction, such as cirrhosis, the liver cannot effectively convert ammonia to urea, leading to its accumulation in the body and subsequently causing hepatic encephalopathy. Choices B, C, and D are incorrect as they do not directly relate to the pathophysiology of hepatic encephalopathy.

Correct Answer: A

Rationale: The correct answer is A. Ferrous sulfate should not be taken with milk as it can impair iron absorption. Choice B is correct as taking the morning dose 1 hour before breakfast is appropriate. Choice C is correct as coffee can interfere with iron absorption. Choice D is correct as antacids should be taken 2 hours after ferrous sulfate to avoid interference with its absorption.

Correct Answer: A

Rationale: When measuring the leg circumference of a client with bipedal edema, the best position to ensure accurate and consistent measurements is the dorsal recumbent position. This position allows the legs to be positioned comfortably, and the individual is lying on their back with legs extended, facilitating accurate measurement of the circumference without the influence of gravity. Sitting, standing, and supine positions may not provide optimal conditions for accurate leg circumference measurements, particularly in clients with bipedal edema where positioning and consistency are crucial. Sitting and standing positions may not allow for consistent leg positioning and could introduce errors due to the effects of gravity on the fluid distribution. The supine position, while similar to dorsal recumbent, may not be as comfortable for the client and could still be influenced by gravity when measuring leg circumference.

Correct Answer: A

Rationale: The correct answer is A. Lying flat in the supine position for 12 hours after a renal biopsy helps prevent bleeding, which is crucial for the client's recovery. This position aids in applying pressure to the biopsy site, reducing the risk of bleeding and ensuring optimal healing. Choices B, C, and D do not directly relate to compliance with client teaching after a renal biopsy. Continuing oral fluids restriction, changing the dressing, or activating a patient-controlled analgesia pump are not specific instructions aimed at promoting recovery and preventing complications post renal biopsy.
