Correct Answer: D

Rationale: The correct answer is D. A cool left foot indicates impaired circulation, which could be a sign of compartment syndrome or impaired blood flow. This finding should be reported to the provider promptly for further evaluation and intervention. Serous drainage on the dressing is expected postoperatively and is not a concerning finding. A capillary refill of 2 seconds is within the normal range (less than 3 seconds is normal), indicating adequate peripheral perfusion. A heart rate of 62/min is also within the normal range for an adult, suggesting no immediate concern related to the surgery.

Correct Answer: B

Rationale: The correct answer is to change the TPN tubing every 24 hours. This action helps reduce the risk of infection because the high glucose content of TPN promotes bacterial growth. Choice A is incorrect as changing the tubing every 48 hours would not provide adequate infection prevention. Option C, monitoring urine output, is important for assessing renal function but is not directly related to preventing TPN-related infections. Option D, monitoring weight, is essential for assessing nutritional status but does not directly address infection prevention in TPN administration.

Correct Answer: D

Rationale: Corrected Rationale: The correct action for the nurse to take when administering insulin glargine is to give it at the same time each day. This consistent timing helps maintain stable blood glucose levels. Choice A is incorrect because insulin glargine should not be administered via IV push. Choice B is incorrect as rotating injection sites is typically done for short-acting insulins to prevent lipodystrophy, not for insulin glargine. Choice C is incorrect as insulin glargine should not be mixed with other insulins before administration.

Correct Answer: D

Rationale: The correct answer is to prepare the client for urinary catheterization. Overflow incontinence may indicate bladder distention, where a bladder scan helps assess the need for catheterization. Placing the client in a supine position (Choice A) is not directly related to the procedure. Obtaining a prescription for an indwelling catheter (Choice B) is not necessary before performing a bladder scan. Cleansing the client's abdomen with an antiseptic solution (Choice C) is not specific to preparing for a bladder scan in this situation.

Correct Answer: C

Rationale: In this scenario, with a fetal heart rate (FHR) baseline of 100/min for 15 minutes, the nurse should suspect maternal hypoglycemia. Maternal hypoglycemia can result in fetal bradycardia, which is defined as an FHR less than 110 beats per minute. Maternal hypoglycemia requires prompt intervention to prevent adverse outcomes for both the mother and the fetus. Maternal fever (Choice A) typically presents with tachycardia rather than bradycardia in the fetus. Fetal anemia (Choice B) is more likely to present with other signs such as pallor or tachycardia rather than bradycardia. Chorioamnionitis (Choice D) is characterized by maternal fever, uterine tenderness, and foul-smelling amniotic fluid, but it is not directly linked to the FHR baseline being 100/min.
