Correct Answer: C

Rationale: The correct position for a client immediately postoperative following a hip arthroplasty is the lateral position with an abduction pillow between the legs. This position helps prevent dislocation of the hip prosthesis and maintains proper alignment of the hip joint. Supine position with legs extended (Choice A) may put stress on the hip joint, Semi-Fowler's position with legs bent (Choice B) may not provide adequate support and alignment, and prone position with legs elevated (Choice D) is not recommended after hip arthroplasty as it can compromise the surgical site and increase the risk of complications.

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: 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.

Correct Answer: B

Rationale: Swelling of the arm above the insertion site is concerning as it can indicate complications like thrombosis, which require immediate attention. Redness at the insertion site is common and expected in the initial stages. A bruised area around the insertion site may result from the insertion procedure and is usually not alarming unless it worsens or becomes larger. A temperature of 37.2°C (99°F) is within the normal range and is not directly related to PICC complications.

Correct Answer: B

Rationale: Yellow-tinged vision is a classic sign of digoxin toxicity due to its effect on the eyes. It can cause a yellow or green visual halo around objects. Bradycardia, constipation, and hypertension are not typical signs of digoxin toxicity. Bradycardia may be a sign of digoxin's therapeutic effect in heart failure, while constipation and hypertension are not commonly associated with digoxin toxicity.
