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?

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 client is receiving Cilostazol (Pletal) for peripheral arterial disease causing intermittent claudication. The nurse determines this medication is effective when the client reports which of the following?

Correct answer: C

Rationale: The correct answer is C. Cilostazol improves blood flow to the muscles, which helps alleviate symptoms of intermittent claudication. An improvement in walking distance without leg pain indicates the effectiveness of the medication. Choices A and B are not directly related to the expected outcome of Cilostazol therapy for intermittent claudication. Choice D is concerning for a potential adverse effect and should be reported to the healthcare provider immediately.

3. A nurse reviews the urinalysis of a client and notes the presence of glucose. Which action should the nurse take?

Correct answer: D

Rationale: Glucose normally is not found in the urine. The normal renal threshold for glucose is about 220 mg/dL, which means that a person whose blood glucose is less than 220 mg/dL will not have glucose in the urine. A positive finding for glucose on urinalysis indicates high blood sugar. The most appropriate action would be to perform a capillary artery glucose assessment. The client needs further evaluation for this abnormal result; therefore, documenting and continuing to monitor is not appropriate. Requesting a 24-hour urine test or reviewing the client’s dietary selections will not assist the nurse to make a clinical decision related to this abnormality.

4. When preparing a client for intravenous pyelography (IVP), which action by the nurse is most important?

Correct answer: D

Rationale: The most crucial action for the nurse when preparing a client for intravenous pyelography (IVP) is to question the client about allergies to iodine or shellfish. Some IVP dyes contain iodine, and if the client is allergic to iodine or shellfish, they may experience severe allergic reactions such as itching, hives, rash, throat tightness, difficulty breathing, or bronchospasm. Administering a sedative (Choice A) may be needed for relaxation during the procedure, encouraging fluid intake (Choice B) is generally beneficial but not the most crucial for IVP preparation, and administering radiopaque dye (Choice C) should only be done after confirming the client's safety regarding allergies to iodine or shellfish.

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

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.
