CERTIFICATION PREPARATION
1. A nurse is preparing to administer a medication that undergoes extensive first-pass
metabolism. Which route would most effectively bypass first-pass metabolism?
A. Oral
B. Sublingual
C. Enteral tube
D. Rectal
Correct Answer: B. Sublingual
Rationale:
The sublingual route allows medication to enter systemic circulation directly through oral
mucosa, largely avoiding first-pass hepatic metabolism. Oral and enteral routes pass through
the gastrointestinal tract, while rectal administration only partially avoids first-pass metabolism.
2. A patient taking warfarin is prescribed a new medication. Which laboratory value
should the nurse monitor most closely?
A. Hemoglobin A1c
B. Serum creatinine
C. INR
D. Potassium
Correct Answer: C. INR
Rationale:
INR reflects the anticoagulant effect of warfarin and helps identify increased bleeding risk or
subtherapeutic anticoagulation. The other values may be important but do not directly measure
warfarin effectiveness.
3. Which adverse effect should the nurse anticipate in a patient receiving opioid analgesics?
A. Hypertension
B. Diarrhea
C. Tachycardia
D. Constipation
Correct Answer: D. Constipation
Rationale:
Opioids commonly reduce gastrointestinal motility, leading to constipation. Patients often
require preventive bowel regimens. Diarrhea is uncommon with opioid therapy.
4. A patient receiving an ACE inhibitor develops a persistent dry cough. What is the most
appropriate nursing action?
,A. Advise the patient to discontinue the drug immediately
B. Notify the provider of the adverse effect
C. Administer a bronchodilator
D. Encourage increased sodium intake
Correct Answer: B. Notify the provider of the adverse effect
Rationale:
Dry cough is a common adverse effect of ACE inhibitors. The provider may switch therapy to
another antihypertensive class, such as an ARB.
5. Which statement by a patient taking nitroglycerin indicates understanding of medication
teaching?
A. “I will swallow the tablet immediately.”
B. “I will store the tablets in a bathroom cabinet.”
C. “I will place the tablet under my tongue during chest pain.”
D. “I can use expired tablets safely.”
Correct Answer: C. “I will place the tablet under my tongue during chest pain.”
Rationale:
Nitroglycerin sublingual tablets should be placed under the tongue for rapid absorption during
angina episodes. Proper storage and expiration monitoring are essential.
6. A nurse is reviewing a medication order. Which abbreviation should be clarified before
administration?
A. mg
B. PO
C. daily
D. U
Correct Answer: D. U
Rationale:
The abbreviation “U” for units can be mistaken for a zero or other notation, increasing
medication error risk. It should be written out as “units.”
7. Which medication classification is most commonly associated with hyperkalemia?
A. Loop diuretics
B. ACE inhibitors
C. Thiazide diuretics
D. Osmotic diuretics
Correct Answer: B. ACE inhibitors
Rationale:
ACE inhibitors reduce aldosterone secretion, increasing potassium retention. Monitoring
potassium levels is an important safety measure.
8. A patient reports taking double the prescribed dose of insulin by mistake. What is the
nurse's priority assessment?
A. Hearing acuity
B. Skin turgor
C. Signs of hypoglycemia
, D. Deep tendon reflexes
Correct Answer: C. Signs of hypoglycemia
Rationale:
Excess insulin can rapidly lower blood glucose, making hypoglycemia the most immediate
concern requiring prompt assessment and intervention.
9. Which factor most directly influences drug distribution?
A. Gastric pH
B. Protein binding
C. Tablet color
D. Medication cost
Correct Answer: B. Protein binding
Rationale:
Protein-bound drugs remain largely inactive while bound. Changes in protein levels can
significantly affect drug distribution and therapeutic effects.
10. A patient prescribed furosemide should be monitored for which electrolyte imbalance?
A. Hypercalcemia
B. Hypermagnesemia
C. Hypernatremia
D. Hypokalemia
Correct Answer: D. Hypokalemia
Rationale:
Loop diuretics promote potassium loss, increasing the risk of hypokalemia, which can contribute
to cardiac dysrhythmias.
11. Which patient statement suggests a need for further teaching about antibiotics?
A. “I will complete the entire prescription.”
B. “I can stop the medication when symptoms improve.”
C. “I will report severe diarrhea.”
D. “I should take doses as prescribed.”
Correct Answer: B. “I can stop the medication when symptoms improve.”
Rationale:
Stopping antibiotics early may contribute to treatment failure and antimicrobial resistance. Full-
course completion is essential.
12. A patient receiving digoxin develops nausea and visual disturbances. What should the
nurse suspect?
A. Therapeutic effect
B. Drug allergy
C. Digoxin toxicity
D. Hypertension
Correct Answer: C. Digoxin toxicity
Rationale:
Nausea, vomiting, and visual disturbances are classic indicators of digoxin toxicity and require
immediate evaluation.
