Question 1
Clinical Scenario
A 68-year-old man is admitted with community-acquired
pneumonia and dehydration. His medical history includes
hypertension, type 2 diabetes mellitus, and chronic kidney
disease (stage 3). The provider prescribes an intravenous
antibiotic. Before administering the medication, the nurse
reviews the patient's allergies, current medications, renal
function, and recent laboratory results. The patient's serum
creatinine is 2.0 mg/dL (baseline 1.8 mg/dL), and he reports a
previous rash after taking penicillin many years ago.
Question Stem
,Which nursing action best demonstrates safe medication
administration before giving the first dose of the prescribed
antibiotic?
A. Administer the medication immediately because the
prescription has been verified by the provider.
B. Verify the patient's allergy history, assess the nature of the
previous reaction, and review renal function before
administering the medication.
C. Delay the medication until the patient's serum creatinine
returns to the normal range.
D. Administer half of the prescribed dose because the patient
has chronic kidney disease.
Correct Answer
Correct Answer: B. Verify the patient's allergy history, assess
the nature of the previous reaction, and review renal function
before administering the medication.
Detailed Rationale
Medication administration begins with a comprehensive nursing
assessment rather than simply following the medication order.
Reviewing allergy history helps distinguish between a true
immunologic allergy and a nonallergic adverse reaction, which
directly influences medication selection and patient safety.
Assessing renal function is equally important because many
,antibiotics are eliminated through the kidneys and may require
dosage adjustments to prevent toxicity. By gathering this
information before administration, the nurse reduces the risk of
preventable medication-related harm and promotes
individualized pharmacotherapy.
Option A is incorrect because provider verification does not
replace the nurse's independent responsibility to assess
medication safety before administration.
Option C is incorrect because delaying antibiotic therapy
without provider consultation could worsen the patient's
infection. Instead, the nurse should determine whether dosage
adjustment or an alternative antibiotic is needed.
Option D is incorrect because nurses should never
independently alter prescribed medication dosages. Dose
adjustments require a provider's order based on clinical
assessment and renal function.
Patient teaching should include reporting previous allergic
reactions accurately and informing healthcare providers about
kidney disease. Continuous monitoring for hypersensitivity
reactions and therapeutic response should occur after
administration.
Learning Objectives
After completing this question, the learner should be able to:
, • Perform a comprehensive medication safety assessment
before administering medications.
• Differentiate allergy assessment from adverse effect
assessment.
• Recognize the importance of renal function when
administering medications.
• Apply nursing accountability during medication
administration.
Medication Safety Focus
Medication administration
Question 2
Clinical Scenario
A newly licensed nurse asks an experienced nurse to explain
why some medications require multiple daily doses while others
are given only once each day. The experienced nurse explains
that understanding basic pharmacokinetic principles helps
ensure medications maintain therapeutic effects while
minimizing toxicity.
Question Stem
Which pharmacokinetic process primarily determines how long
a medication remains active in the body?
