NURS 220 Module 4 Exam 2026
Exam Questions and Verified
Answers | Already Graded A+
A nurse is caring for a patient with a history of chronic obstructive
pulmonary disease (COPD) admitted for pneumonia. What laboratory
finding would be consistent with decreased kidney function in this patient?
A. Serum uric acid 5.2 mg/dL
B. Uric specific gravity of 1.040
,C. Serum Creatinine of 2.3 mg/dL
D. Blood urea nitrogen (BUN) of 10 mg/dL - 🧠 ANSWER ✔✔C. Serum
Creatinine of 2.3 mg/dL
Rationale: An expected assessment finding related to decreased kidney
function in the aging process is an increased serum creatinine. Other
expected assessments include an elevated BUN and inability to
concentrate urine (with urine specific gravity fixed at 1.010). Uric acid is
used as a screening test for disorders of purine metabolism or kidney
disease; values depend on renal function, rate of purine metabolism, and
dietary intake of food rich in purines. Normal reference intervals: serum
creatinine, 0.6 to 1.3 mg/dL; BUN, 6 to 20 mg/dL; urine specific gravity,
1.003 to 1.030; and serum uric acid, 2.3 to 6.6 mg/dL (female) or 4.4 to 7.6
mg/dL (male).
A patient was admitted 2 weeks ago after multiple traumatic injuries in a
motor vehicle collision. The patient now has a serum creatinine at 3.9
mg/dL and a blood urea nitrogen (BUN) of 100 mg/dL. Which medication, if
ordered by the health care provider, should the nurse question?
,A. Gentamicin
B. Nitrofurantoin
C. Acetaminophen
D. Morphine sulfate - 🧠 ANSWER ✔✔A. Gentamicin
Rationale: Elevated serum creatinine and BUN indicate renal insufficiency
or acute kidney injury. Medications (e.g., prescribed, over-the-counter, and
herbs) should be evaluated for nephrotoxic potential. Many drugs are
known to be nephrotoxic (see Table 44-3); gentamicin is a potential
nephrotoxic agent.
A patient in the intensive care unit is receiving gentamicin for treatment of
pneumonia from Pseudomonas aeruginosa. What assessment results
should the nurse report to the health care provider?
A. Decreased weight
B. Increased appetite
C. Increased urinary output

, D. Elevated creatinine levels - 🧠 ANSWER ✔✔D. Elevated creatinine levels
Rationale: Gentamicin can be toxic to the kidneys and the auditory system.
The elevated creatinine level must be reported to the physician because it
probably indicates renal damage. Other factors that may occur with renal
damage would include increased weight and decreased urinary output.
Many medications have side effects of anorexia.
A patient underwent a surgical procedure has a urinary catheter. Eight
hours after catheter removal and drinking fluids, the patient has not been
able to void. What is the nurse's first action to assess for urinary retention?
A. Bladder scan
B. Cystometrogram
C. Residual urine test
D. Kidneys, ureaters, Bladder (KUB) x-ray - 🧠 ANSWER ✔✔A. Bladder
scan
