Question 1
Clinical Scenario
A 67-year-old man is admitted with community-acquired
pneumonia. His history includes hypertension, osteoarthritis,
and chronic kidney disease stage 3. The provider prescribes an
oral antibiotic. During medication reconciliation, the nurse
learns the client takes an over-the-counter antacid containing
calcium carbonate several times daily. Vital signs are stable, and
laboratory values are within expected ranges for the client's
condition.
Question Stem
,Which nursing action is most appropriate before administering
the antibiotic?
A. Administer the antibiotic with the antacid to reduce
gastrointestinal upset.
B. Assess whether the antacid may interfere with absorption of
the prescribed medication.
C. Hold the antibiotic until the client's serum calcium level is
available.
D. Encourage the client to crush the antibiotic and mix it with
applesauce.
Correct Answer
Correct Answer: B. Assess whether the antacid may interfere
with absorption of the prescribed medication.
Detailed Rationale
Medication reconciliation is a critical component of safe
pharmacologic care because prescription medications, over-the-
counter products, and supplements may significantly affect
therapeutic outcomes. Many orally administered medications,
including several antibiotics, have reduced absorption when
taken with calcium-containing antacids. Identifying this
interaction allows the nurse to recommend separating
administration times or notifying the provider if needed. This
,intervention helps maintain therapeutic drug concentrations
and supports effective treatment.
Option A is incorrect because administering the medication
simultaneously with a calcium-containing antacid may decrease
drug absorption and reduce therapeutic effectiveness.
Option C is incorrect because serum calcium is unrelated to the
primary concern. The priority is identifying a potential drug
interaction before administration.
Option D is incorrect because crushing medications should
never occur unless the formulation is known to be safe for
crushing. Some tablets are enteric-coated or extended-release
and should remain intact.
Medication reconciliation helps prevent avoidable medication
errors, improves therapeutic outcomes, and promotes patient
safety. Nurses should routinely ask about prescription drugs,
herbal products, vitamins, and over-the-counter medications
before administering new medications.
Learning Objectives
After completing this question, the learner should be able to:
• Identify the purpose of medication reconciliation.
• Recognize common drug–drug interactions involving oral
medications.
, • Apply safe medication administration principles.
• Promote therapeutic medication effectiveness.
Medication Safety Focus
Medication Reconciliation
Question 2
Clinical Scenario
A 72-year-old woman is admitted with heart failure. She has
mild cognitive impairment and takes eight prescribed
medications at home. During assessment, she states, "I
sometimes skip doses because I forget which pills I've already
taken."
Question Stem
Which nursing intervention is most effective in reducing this
client's risk for medication errors after discharge?
A. Recommend discontinuing nonessential medications
independently.
B. Suggest using a weekly pill organizer and maintaining an
updated medication list.
C. Encourage taking all medications together once daily.
