Question 1 of 5
The nurse is caring for a patient who is admitted with pneumonia. The nurse notes a blood urea nitrogen (BUN) of 32 mg/dL and creatinine of 0.8 mg/dL. What is the most probable explanation for this finding?
Correct Answer: C
Rationale: Elevated BUN (32 mg/dL) with normal creatinine (0.8 mg/dL) suggests dehydration (C), concentrating blood urea. Kidney damage (A) would raise creatinine, septicemia (B) isn't indicated, and malnutrition (D) lowers BUN, making C the likely cause.
Question 2 of 5
The nurse is assessing a patients bladder by percussion. The nurse elicits dullness after the patient has voided. How should the nurse interpret this assessment finding?
Correct Answer: A
Rationale: Dullness post-voiding (A) indicates incomplete bladder emptying, as urine muffles sound. Kidney enlargement (B), obstruction (C), or dehydration (D) don't cause bladder dullness directly; they reduce urine flow, making A the interpretation.
Question 3 of 5
Diagnostic testing of an adult patient reveals renal glycosuria. The nurse should recognize the need for the patient to be assessed for what health problem?
Correct Answer: C
Rationale: Renal glycosuria often indicates diabetes mellitus (C), where high blood glucose exceeds reabsorption capacity. It's benign alone but not linked to DI (A), SIADH (B), or carcinoma (D), making C the assessment focus.
Question 4 of 5
A client with generalized anxiety disorder asks how buspirone helps. What is the nurse's best response?
Correct Answer: B
Rationale: Buspirone reduces anxiety by modulating serotonin and dopamine activity.
Question 5 of 5
The nurse is assessing a patient suspected of having developed acute glomerulonephritis. The nurse should expect to address what clinical manifestation that is characteristic of this health problem?
Correct Answer: A
Rationale: The primary presenting feature of acute glomerulonephritis is hematuria (blood in the urine), which may be microscopic (identifiable through microscopic examination) or macroscopic or gross (visible to the eye). Proteinuria, primarily albumin, which is present, is due to increased permeability of the glomerular membrane. Blood urea nitrogen (BUN) and serum creatinine levels may rise as urine output drops. Some degree of edema and hypertension is noted in most patients.
