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. The client with peripheral artery disease has been prescribed clopidogrel (Plavix). The nurse understands that more teaching is necessary when the client states which of the following?

• A. I should not be surprised if I bruise more easily or if my gums bleed a little when brushing my teeth.
• B. It is important to take this medicine with food to enhance its effectiveness and minimize stomach upset.
• C. I should stop taking Plavix if it makes me feel weak and dizzy.
• D. The doctor prescribed this medicine to make my platelets less likely to stick together and help prevent clots from forming.

Correct answer: C

Rationale: The correct answer is C. Weakness, dizziness, and headache are common adverse effects of Plavix and should be reported. It is essential to consult a physician before stopping Plavix as it plays a crucial role in preventing platelets from sticking together and forming clots. Choices A, B, and D are incorrect. Choice A is a common side effect of Plavix and does not indicate a need for further teaching. Choice B is incorrect because taking Plavix with or without food can affect its absorption and effectiveness. Choice D correctly explains the purpose of prescribing Plavix to prevent clot formation.

3. What is the most important nursing intervention for a patient with increased intracranial pressure (ICP)?

• A. Elevate the head of the bed to 30 degrees.
• B. Administer diuretics to reduce fluid volume.
• C. Administer corticosteroids to reduce inflammation.
• D. Keep the patient in a supine position.

Correct answer: A

Rationale: Elevating the head of the bed to 30 degrees is crucial for a patient with increased intracranial pressure (ICP) because it helps promote venous drainage from the brain, thereby reducing ICP. Keeping the head of the bed elevated helps facilitate cerebral perfusion and can prevent a further increase in ICP. Administering diuretics (Choice B) may be considered in some cases to reduce fluid volume, but it is not the most critical intervention for immediate ICP management. Administering corticosteroids (Choice C) is not typically indicated for managing increased ICP unless there is a specific underlying condition requiring their use. Keeping the patient in a supine position (Choice D) can actually worsen ICP by impeding venous outflow from the brain, making it an incorrect choice for this scenario.

4. The client with chronic renal failure is on a fluid restriction. Which of the following statements by the client indicates that the teaching has been effective?

• A. I will limit my fluid intake to prevent fluid overload.
• B. I can drink as much fluid as I want as long as I take my medication.
• C. I will skip dialysis sessions if I feel tired.
• D. I will limit my fluid intake to 1 liter per day.

Correct answer: A

Rationale: Choice A is the correct answer because it demonstrates the client's understanding of the need to limit fluid intake to prevent fluid overload, which is crucial in managing chronic renal failure. Adequate fluid restriction is essential to prevent complications such as fluid overload and electrolyte imbalances. Choice B is incorrect as it promotes excessive fluid intake, which can worsen the client's condition by putting additional stress on the kidneys. Choice C is incorrect as skipping dialysis sessions can lead to a buildup of toxins in the body, worsening renal failure and potentially leading to life-threatening complications. Choice D is incorrect because limiting fluid intake to a specific volume may not be appropriate for all clients and can vary depending on individual needs, medical condition, and healthcare provider recommendations.

5. A patient is admitted to the hospital for treatment of pneumonia after complaining of high fever and shortness of breath. The patient was not able to produce sputum for a culture. The nurse will expect the patient’s provider to order

• A. a broad-spectrum antibiotic.
• B. a narrow-spectrum antibiotic.
• C. multiple antibiotics.
• D. the pneumococcal vaccine.

Correct answer: A

Rationale: In this scenario where the offending organism causing pneumonia is unknown due to the inability to produce sputum for culture, the appropriate choice is a broad-spectrum antibiotic. Broad-spectrum antibiotics are effective against a wide range of bacteria and are commonly used when the specific pathogen is unidentified. Narrow-spectrum antibiotics target specific types of bacteria and are chosen based on culture and sensitivity results. Using multiple antibiotics without a clear indication from culture and sensitivity testing can lead to antibiotic resistance and is not recommended in this situation. Additionally, the pneumococcal vaccine is preventive and does not treat an ongoing infection like pneumonia.
