Nursing Elites

1. In a 46-year-old female client admitted for acute renal failure secondary to diabetes and hypertension, which test is the best indicator of adequate glomerular filtration?

• A. Serum creatinine.
• B. Blood urea nitrogen (BUN).
• C. Sedimentation rate.
• D. Urine specific gravity.

Correct answer: A

Rationale: The correct answer is A: Serum creatinine. Creatinine is a product of muscle metabolism that is filtered by the glomerulus. Blood levels of creatinine are not affected by dietary or fluid intake, making it a reliable indicator of kidney function. An elevated creatinine level strongly suggests nephron loss, indicating decreased glomerular filtration rate. Choice B, Blood Urea Nitrogen (BUN), reflects the amount of urea nitrogen in the blood and can be influenced by factors other than kidney function, such as protein intake and liver health, making it less specific for evaluating glomerular filtration. Choice C, Sedimentation rate, is a measure of how quickly red blood cells settle in a test tube and is not a direct marker of kidney function. Choice D, Urine specific gravity, mainly reflects the kidney's ability to concentrate urine and is not a direct indicator of glomerular filtration rate. Therefore, Serum creatinine is the most appropriate test to assess glomerular filtration in this scenario.

2. A nurse is assessing the chest tube drainage system of a postoperative client who has undergone a right upper lobectomy. The closed drainage system contains 300 mL of bloody drainage, and the nurse notes intermittent bubbling in the water seal chamber. One hour after the initial assessment, the nurse notes that the bubbling in the water seal chamber is now constant, and the client appears dyspneic. On the basis of these findings, the nurse should first assess:

• A. The client’s vital signs
• B. The amount of drainage
• C. The client’s lung sounds
• D. The chest tube connections

Correct answer: D

Rationale: The client’s dyspnea is most likely related to an air leak caused by a loose connection in the chest tube system. Checking the chest tube connections should be the initial action because correcting an air leak can quickly resolve the client's symptoms. If a leak is found and corrected, the dyspnea should improve. Assessing the client’s vital signs (Option A) is important, but addressing the potential cause of dyspnea takes precedence. Monitoring the amount of drainage (Option B) is necessary for assessing the client's overall condition, but in this case, the dyspnea is likely due to an air leak. Checking the client’s lung sounds (Option C) is essential for respiratory assessment, but addressing the air leak should be the immediate priority to ensure adequate lung expansion and oxygenation.

3. Which of the following conditions is most commonly associated with a high risk of stroke?

• A. Hypertension.
• B. Diabetes.
• C. Obesity.
• D. Smoking.

Correct answer: A

Rationale: Hypertension is the correct answer. Hypertension, also known as high blood pressure, is a major risk factor for stroke because it puts increased pressure on blood vessels in the brain, making them more prone to damage and increasing the likelihood of a stroke. While diabetes, obesity, and smoking are also risk factors for stroke, hypertension is the most commonly associated condition with a high risk of stroke due to its direct impact on the blood vessels.

4. The nurse is caring for a client who is receiving an IV infusion of normal saline and notices that the infusion is not flowing. The insertion site is not inflamed or swollen. What should the nurse do first?

• A. Check the tubing for kinks or obstructions.
• B. Increase the flow rate to improve the infusion.
• C. Reinsert the IV catheter in another vein.
• D. Call the physician for further instructions.

Correct answer: A

Rationale: The correct first action for the nurse to take when an IV infusion is not flowing despite a normal insertion site is to check the tubing for kinks or obstructions. This step is crucial to ensure that there are no preventable issues impeding the flow of the IV solution. Increasing the flow rate without addressing potential obstructions could lead to complications such as infiltration. Reinserting the IV catheter in another vein should only be considered after ruling out tubing issues. Calling the physician for further instructions is not necessary at this stage as troubleshooting the tubing should be the initial intervention.

5. A young adult is burned when wearing a shirt that was splashed with lighter fluid and caught on fire while attempting to light a charcoal grill. The client ripped off the shirt immediately, without unbuttoning the sleeves, which caused circumferential burns to both wrists. When the client is admitted, which intervention should the nurse implement first?

• A. Monitor pulse intensity.
• B. Evaluate extremity sensation.
• C. Assess range of motion.
• D. Place sterile bandage on both wrists.

Correct answer: A

Rationale: Monitoring pulse intensity is the priority to ensure circulation is not compromised due to circumferential burns.
