Correct Answer: D

Rationale: The correct answer is to monitor the insertion site for redness. This intervention helps detect signs of infection early in clients with intraventricular catheters. Keeping the head of the bed elevated to 30 degrees is important for managing intracranial pressure but does not directly reduce the risk of infection. Administering IV antibiotics prophylactically is not recommended as a routine practice due to the risk of antibiotic resistance and should only be done based on culture results. Changing the catheter insertion site every 24 hours is unnecessary and increases the risk of introducing new pathogens.

Correct Answer: B

Rationale: The correct answer is B: 'Heart rate of 88/min.' A heart rate of 88/min in a postoperative client can be an early sign of bleeding or other complications. It is essential to report this finding promptly to the healthcare provider for further evaluation and intervention. Choices A, C, and D are within normal ranges for a postoperative client and do not indicate immediate concern. A blood pressure of 118/76 mm Hg is normal, urinary output of 30 mL/hr may be adequate depending on the client's fluid status, and a hematocrit of 42% is within the acceptable range for a postoperative client. Therefore, they do not require immediate reporting.

Correct Answer: B

Rationale: The correct answer is B. Limiting protein intake is crucial for clients with chronic kidney disease as it helps prevent further kidney damage. Increasing intake of potassium-rich foods (choice A) is not recommended for clients with kidney disease as high potassium levels can be harmful. Avoiding foods high in phosphorus (choice C) is important, but limiting protein intake is a higher priority. Increasing dairy product intake (choice D) is not ideal for clients with kidney disease as they may need to monitor their phosphorus intake from such foods.

Correct Answer: C

Rationale: Elevated serum creatinine levels indicate impaired kidney function. As kidney disease progresses, the kidneys are less able to filter waste products, leading to an increase in creatinine levels. Therefore, a high serum creatinine level of 2.5 mg/dL should be reported to the provider for further evaluation and management. Choices A, B, and D are within normal ranges and do not directly signify worsening kidney function in this context.

Correct Answer: A

Rationale: Corrected Rationale: Daily weight monitoring is crucial in managing patients with chronic heart failure as it helps assess fluid balance. Monitoring daily weight allows healthcare providers to detect any sudden weight gain, which could indicate fluid retention and worsening heart failure. This intervention helps in adjusting treatment plans promptly. Providing fluid restriction (Choice B) can be a part of managing heart failure but is not the primary intervention mentioned in the question. Administering diuretics (Choice C) is a treatment modality for heart failure but does not encompass the comprehensive approach to patient management. Monitoring intake and output (Choice D) is important but does not specifically address the direct assessment of fluid status as daily weight monitoring does.
