Nursing Elites

1. Following a lumbar puncture, a client complains of worsening headache when sitting up. What complication is the client likely experiencing?

• A. A migraine headache
• B. An infection from the puncture site
• C. Low blood sugar
• D. Spinal fluid leakage (post-lumbar puncture headache)

Correct answer: D

Rationale: The client is likely experiencing spinal fluid leakage (post-lumbar puncture headache), a common complication of a lumbar puncture. This leakage results in a reduction of cerebrospinal fluid volume around the brain and spinal cord, leading to a headache that worsens when in an upright position due to reduced buoyancy. A migraine headache (Choice A) is not typically associated with a lumbar puncture. Infection from the puncture site (Choice B) would present with localized signs of inflammation, such as redness, swelling, and warmth, rather than worsening headache. Low blood sugar (Choice C) is not a common complication of lumbar puncture and would not typically manifest as a worsening headache when sitting up.

2. Prior to administering warfarin to a client with a history of atrial fibrillation, what lab result should the nurse review?

• A. White blood cell count.
• B. Prothrombin time (PT) and International Normalized Ratio (INR).
• C. Hemoglobin and hematocrit.
• D. Blood urea nitrogen (BUN) and creatinine.

Correct answer: B

Rationale: The correct answer is B: Prothrombin time (PT) and International Normalized Ratio (INR). These lab values are crucial for monitoring the effectiveness of warfarin, an anticoagulant medication. PT measures the time it takes for blood to clot, while INR standardizes these results. Ensuring the client's PT/INR levels are within the therapeutic range is essential to prevent clotting or excessive bleeding. Choices A, C, and D are incorrect as they are not directly related to monitoring warfarin therapy in a client with atrial fibrillation.

3. A client with Crohn's disease reports diarrhea. What intervention should the nurse implement?

• A. Instruct the client to drink clear fluids and avoid solid foods.
• B. Administer antidiarrheal medication as prescribed.
• C. Encourage a high-fiber diet and regular physical activity.
• D. Restrict fluid intake and monitor electrolytes.

Correct answer: C

Rationale: The correct intervention for a client with Crohn's disease reporting diarrhea is to encourage a high-fiber diet and regular physical activity. A high-fiber diet helps manage diarrhea in Crohn's disease by adding bulk to the stool and promoting more regular bowel movements. Instructing the client to drink clear fluids and avoid solid foods (Choice A) may not be appropriate as it can further exacerbate diarrhea. Administering antidiarrheal medication (Choice B) without addressing the underlying cause may not be the best initial approach. Encouraging a high-fiber diet and physical activity (Choice C) is beneficial for managing symptoms. Restricting fluid intake and monitoring electrolytes (Choice D) is not recommended as it can lead to dehydration, which is a concern in clients with diarrhea.

4. The nurse is preparing to administer a subcutaneous injection to a thin, elderly client. What is the most appropriate site for the injection?

• A. Dorsal aspect of the upper arm.
• B. Upper outer thigh.
• C. Lower abdomen.
• D. Lateral aspect of the upper arm.

Correct answer: B

Rationale: The correct answer is the upper outer thigh. In thin, elderly clients, the upper outer thigh is a recommended site for subcutaneous injections due to the presence of adequate subcutaneous tissue and muscle mass. The dorsal aspect of the upper arm may not provide enough subcutaneous tissue for proper absorption of the medication. The lower abdomen is not ideal for thin individuals as it may lead to injection into muscle rather than subcutaneous tissue. The lateral aspect of the upper arm is also not a commonly recommended site for subcutaneous injections.

5. A client with chronic kidney disease has a potassium level of 6.2 mEq/L. Which intervention should the nurse implement?

• A. Encourage the client to eat foods rich in potassium
• B. Administer a potassium-sparing diuretic
• C. Administer a potassium-binding medication
• D. Hold all medications containing potassium

Correct answer: C

Rationale: A potassium level of 6.2 mEq/L indicates hyperkalemia, which is dangerous and requires immediate treatment. Administering a potassium-binding medication will help lower potassium levels and prevent life-threatening complications.
