,Q1. A client with type 2 diabetes is prescribed metformin. Which laboratory value
requires immediate assessment before continuing the medication?
A. Serum creatinine 1.8 mg/dL
B. Hemoglobin A1c 7.2%
C. Fasting blood glucose 126 mg/dL
D. ALT 45 U/L
Correct Answer: A. Serum creatinine 1.8 mg/dL
Rationale: Metformin is contraindicated in renal impairment (eGFR <30 mL/min) due to
risk of lactic acidosis. A serum creatinine of 1.8 mg/dL suggests significant renal
dysfunction, requiring discontinuation or dose adjustment. Elevated A1c and fasting
glucose indicate poor control but are not contraindications. ALT elevation may warrant
monitoring but is not an absolute contraindication.
Why Wrong:
B - Elevated A1c indicates hyperglycemia, not a contraindication to metformin.
C - Fasting glucose elevation is an indication for therapy, not a contraindication.
D - Mild ALT elevation does not preclude metformin use, though liver function
should be assessed.

Q2. A nurse is reviewing a client's medication list and notes a prescription for
digoxin. Which finding increases the risk of digoxin toxicity?
A. Concurrent use of furosemide
B. Serum potassium 4.2 mEq/L
C. Concurrent use of metoprolol
D. Serum magnesium 1.8 mEq/L
Correct Answer: A. Concurrent use of furosemide
Rationale: Furosemide can cause hypokalemia, which potentiates digoxin toxicity by
increasing myocardial sensitivity to digoxin. Normal potassium and magnesium levels are
not risk factors. Metoprolol is used with digoxin for rate control but does not increase
toxicity risk directly.
Why Wrong:
B - Normal potassium is not a risk factor for digoxin toxicity.
C - Metoprolol does not increase digoxin toxicity risk.
D - Normal magnesium is not a risk factor for digoxin toxicity.
Reference: Lehne, R.A. (2026). Pharmacology for Nursing Care, 12th Ed., Ch. 32
Q3. A client is prescribed an opioid analgesic. Which assessment finding indicates the
need for immediate intervention to prevent respiratory depression?
A. Respiratory rate 10 breaths/min
Page 3
, B. Oxygen saturation 95% on room air
C. Pupil constriction
D. Sedation score of 2 on Ramsay scale
Correct Answer: A. Respiratory rate 10 breaths/min
Rationale: A respiratory rate below 12 breaths/min indicates respiratory depression, a
life-threatening adverse effect of opioids. Oxygen saturation may be maintained initially
due to compensatory mechanisms. Pupil constriction is expected. Sedation score of 2
indicates adequate sedation, not impending depression.
Why Wrong:
B - Oxygen saturation 95% is within normal limits, though may decline later.
C - Pupil constriction is an expected opioid effect, not a sign of respiratory depression.
D - Sedation score of 2 is acceptable; a higher score would indicate oversedation.
Reference: Lehne, R.A. (2026). Pharmacology for Nursing Care, 12th Ed., Ch. 14
Q4. A client with hypertension is prescribed lisinopril. Which adverse effect requires
the nurse to notify the healthcare provider immediately?
A. Dry cough
B. Angioedema with lip swelling
C. Dizziness upon standing
D. Hyperkalemia with potassium 5.2 mEq/L
Correct Answer: B. Angioedema with lip swelling
Rationale: Angioedema is a life-threatening adverse effect of ACE inhibitors, requiring
immediate discontinuation and emergency care. Dry cough is bothersome but not
life-threatening. Dizziness may occur due to hypotension, but is not immediately
life-threatening. Hyperkalemia requires monitoring and possible dose adjustment but is
not as urgent as angioedema.
Why Wrong:
A - Dry cough is common but not an emergency.
C - Dizziness may indicate hypotension but is not immediately life-threatening.
D - Hyperkalemia is serious but not as immediately life-threatening as angioedema.
Reference: Lehne, R.A. (2026). Pharmacology for Nursing Care, 12th Ed., Ch. 36
Q5. A client is receiving intravenous vancomycin. The nurse notes the client has a
rash on the trunk and neck. Which action is most appropriate?
A. Document the finding as an expected adverse effect.
B. Stop the infusion and notify the healthcare provider.
C. Administer diphenhydramine and continue the infusion.
D. Slow the infusion rate and continue to monitor.
