Correct Answer: D

Rationale: The correct answer is D. A prothrombin time of 18 seconds is most concerning in a client with hepatic encephalopathy as it indicates impaired liver function and an increased risk of bleeding. This requires immediate intervention to prevent bleeding complications. Choice A, serum ammonia level of 80 mcg/dl, is elevated but not as urgent as the abnormal prothrombin time. Choice B, bilirubin level of 3.0 mg/dl, is elevated but does not directly indicate an urgent need for intervention in this situation. Choice C, serum sodium level of 135 mEq/L, is within the normal range and does not require immediate intervention.

Correct Answer: A

Rationale: The correct answer is A: Elevated blood pressure. In a client with chronic kidney disease (CKD) receiving erythropoietin therapy, elevated blood pressure requires immediate intervention. This finding is concerning as it may indicate worsening hypertension, which can lead to further complications. Increased fatigue (choice B) is common in CKD but may not require immediate intervention unless severe. Headache (choice C) can be a symptom to monitor but does not pose an immediate threat like elevated blood pressure. Elevated hemoglobin (choice D) is actually a desired outcome of erythropoietin therapy and does not require immediate intervention.

Correct Answer: B

Rationale: The correct answer is B. Explaining that hand rubs can be effective with less time allows the UAP to perform the procedure more efficiently while maintaining asepsis. Choice A is incorrect because the UAP does not need to remain in the client's room until the procedure is completed. Choice C is incorrect as the UAP was using an alcohol-based gel hand cleaner, not handwashing. Choice D is incorrect as the scenario does not mention any issue with glove usage, so it is not relevant to the situation at hand.

Correct Answer: A

Rationale: The correct answer is A: 'Your baby is gaining weight right on schedule.' Tripling of birth weight by 6 months is a normal growth pattern in infants, indicating appropriate weight gain and development. Choice B is unrelated to the question as it focuses on the baby's diet rather than addressing the weight gain concern. Choice C is incorrect as tripling the birth weight is considered a healthy growth pattern, not below normal percentile. Choice D is irrelevant to the mother's question about the adequacy of weight gain.

Correct Answer: A

Rationale: The correct answer is to ensure the catheter is always below the level of the bladder. Placing the catheter tubing above the level of the bladder can lead to backflow of urine, causing urinary tract infections. Changing the catheter bag every 48 hours is important but not as crucial as maintaining proper catheter positioning. Cleaning the perineal area daily and performing catheter care are essential tasks but do not directly address the prevention of complications associated with catheter placement.
