Correct Answer: B

Rationale: The correct answer is to place the client on bedrest. Placing the client on bedrest is the priority intervention as it helps prevent the risk of embolization from the DVT, which could lead to a life-threatening pulmonary embolism. Administering anticoagulant therapy, elevating the client's right leg, or applying compression stockings are important interventions in managing DVT but should come after ensuring the client is on bedrest to prevent the dislodgment of the clot.

Correct Answer: C

Rationale: The correct answer is C. A fever of 100.4°F is most concerning in a client with ESRD scheduled for hemodialysis as it may indicate an underlying infection, which can lead to serious complications in this population. Elevated body temperature can be a sign of sepsis, which requires immediate attention to prevent further deterioration. Reporting this finding promptly allows for timely intervention. Choices A, B, and D are within normal ranges and do not pose an immediate threat to the client's well-being in the context of preparing for hemodialysis.

Correct Answer: D

Rationale: The correct action for the nurse to implement after a client with hepatic encephalopathy has loose stools following lactulose administration is to monitor the client's mental status. Lactulose is given to lower serum ammonia levels in hepatic encephalopathy, and loose stools can be an expected side effect of its use. Monitoring mental status is crucial because changes in mental status, such as confusion or altered level of consciousness, are key indicators of hepatic encephalopathy worsening. Sending a stool specimen to the lab would not be the priority in this situation as loose stools are a known effect of lactulose. Measuring abdominal girth is more relevant for conditions like ascites, not loose stools. Encouraging increased fiber in the diet may be beneficial for constipation but is not the immediate action needed when loose stools occur after lactulose administration.

Correct Answer: A

Rationale: A serum potassium level of 6.5 mEq/L is concerning in a client with CKD as it indicates hyperkalemia, which requires immediate intervention to prevent cardiac complications. Hyperkalemia can lead to life-threatening arrhythmias, particularly in patients with impaired kidney function. Serum sodium, creatinine, and blood glucose levels, while important, are not as acutely dangerous as severe hyperkalemia in this context.

Correct Answer: A

Rationale: Administering insulin is the most crucial intervention in managing diabetic ketoacidosis. Insulin helps reduce blood glucose levels and correct metabolic acidosis, which are the primary issues in DKA. Monitoring urine output (Choice B) is important but not as critical as administering insulin. Assessing the client's level of consciousness (Choice C) is essential but does not directly address the underlying cause of DKA. Obtaining an arterial blood gas sample (Choice D) can provide valuable information but is not as urgent as administering insulin to address the immediate metabolic imbalance.
