A client with chronic kidney disease (CKD) is scheduled for a renal biopsy. Which laboratory value is most concerning?

A. Serum potassium of 5.5 mEq/L

B. Serum creatinine of 1.5 mg/dl

C. Serum creatinine of 2.5 mg/dl

D. White blood cell count of 8,000/mm3

Correct Answer: C
Rationale: A serum creatinine level of 2.5 mg/dl is the most concerning laboratory value in a client with chronic kidney disease scheduled for a renal biopsy. An elevated serum creatinine level indicates impaired kidney function, which is critical information before performing a renal biopsy. Option A (Serum potassium of 5.5 mEq/L) may be concerning for hyperkalemia but is not directly related to the renal biopsy procedure. Option B (Serum creatinine of 1.5 mg/dl) is within normal limits, suggesting relatively normal kidney function. Option D (White blood cell count of 8,000/mm3) is within the normal range and not directly related to the renal biopsy procedure or CKD management.

A male client with rheumatoid arthritis is scheduled for a procedure in the morning. The procedure cannot be completed because of early morning stiffness. Which intervention should the nurse implement?

• A. Assign a UAP to assist the client with a warm shower early in the morning.
• B. Provide the client with a warm blanket to reduce stiffness.
• C. Delay the procedure until the client is less stiff.
• D. Encourage the client to perform range-of-motion exercises.

Correct Answer: A
Rationale: A warm shower can help reduce morning stiffness, making the procedure more comfortable for the client. This intervention promotes comfort and mobility, addressing the immediate issue of stiffness. Providing a warm blanket (choice B) may offer some comfort but will not address the stiffness as effectively as a warm shower. Delaying the procedure (choice C) may inconvenience the client and not address the underlying stiffness issue. Encouraging range-of-motion exercises (choice D) is important for long-term management but may not provide immediate relief from the stiffness that is hindering the procedure.

A client is admitted with a diagnosis of septic shock. Which clinical finding requires immediate intervention?

• A. Blood pressure of 90/60 mmHg
• B. Temperature of 100.4°F
• C. Heart rate of 120 beats per minute
• D. Urine output of 30 ml/hour

Correct Answer: C
Rationale: In a client with septic shock, a heart rate of 120 beats per minute is a critical clinical finding that requires immediate intervention. A rapid heart rate can indicate worsening sepsis and inadequate tissue perfusion. Correcting the underlying cause of the tachycardia and stabilizing the heart rate is crucial in managing septic shock. The other options, while important, do not represent an immediate threat to the patient's condition. A blood pressure of 90/60 mmHg may be expected in septic shock, a temperature of 100.4°F is mildly elevated, and a urine output of 30 ml/hour, though decreased, may not be an immediate concern in the context of septic shock.

A nurse is caring for a client with Diabetes Insipidus. Which assessment finding warrants immediate intervention by the nurse?

• A. Hypernatremia
• B. Excessive thirst
• C. Elevated heart rate
• D. Poor skin turgor

Correct Answer: A
Rationale: The correct answer is A: Hypernatremia. In a client with Diabetes Insipidus, hypernatremia, an elevated sodium level in the blood, can lead to neurological symptoms such as confusion, seizures, or coma. Immediate intervention is necessary to prevent these serious complications. Excessive thirst (choice B) is a common symptom of Diabetes Insipidus but does not require immediate intervention. Elevated heart rate (choice C) and poor skin turgor (choice D) are important assessments but are not as critical as hypernatremia in this context.

A client who developed syndrome of inappropriate antidiuretic hormone (SIADH) associated with small carcinoma of the lung is preparing for discharge. When teaching the client about self-management with demeclocycline (Declomycin), the nurse should instruct the client to report which condition to the healthcare provider?

• A. Insomnia
• B. Muscle cramping
• C. Increased appetite
• D. Anxiety

Correct Answer: B
Rationale: The correct answer is B: Muscle cramping. SIADH causes dilutional hyponatremia due to increased ADH release. Demeclocycline is used to block the action of ADH. Muscle cramping can indicate electrolyte imbalances related to hyponatremia, which should be reported to the healthcare provider. Insomnia, increased appetite, and anxiety are not typically associated with the side effects or complications of demeclocycline or SIADH.
