Nursing Exam Study Guid
Question 1 (Easy)
Clinical Scenario
A newly licensed nurse is preparing medications for several
clients on a medical-surgical unit. Before administering a
prescribed oral medication, the nurse compares the medication
administration record (MAR) with the medication label and asks
the client to state their full name and date of birth.
Question Stem
Which nursing principle is the nurse primarily demonstrating?
,A. Promoting medication adherence
B. Following the rights of medication administration
C. Preventing medication tolerance
D. Assessing medication effectiveness
Correct Answer
B. Following the rights of medication administration
Detailed Rationale
The nurse is demonstrating the rights of medication
administration, a fundamental medication safety practice that
helps prevent medication errors. Verifying the medication
against the MAR and confirming the client's identity using two
approved identifiers support the "right patient" and "right
medication." Modern nursing practice also emphasizes
additional rights such as right dose, right route, right time, right
documentation, right reason, right response, and the client's
right to refuse medication. Consistent adherence to these
principles significantly reduces preventable adverse drug
events.
Option A is incorrect because medication adherence refers to
the client's willingness and ability to take medications as
,prescribed after administration, not the nurse's verification
process.
Option C is incorrect because medication tolerance develops
after repeated exposure to certain drugs and is unrelated to
patient identification.
Option D is incorrect because medication effectiveness is
evaluated after administration by assessing therapeutic
outcomes rather than before administration.
Safe medication administration begins with systematic
verification before any medication reaches the patient. Skipping
identification steps can result in serious patient harm, even
when the correct medication has been prepared.
Learning Objectives
After completing this question, the learner should be able to:
• Apply the rights of medication administration.
• Identify appropriate patient identification procedures.
• Recognize nursing actions that prevent medication errors.
Medication Safety Focus
Medication administration
Question 2 (Moderate)
, Clinical Scenario
A 76-year-old woman with chronic kidney disease is prescribed
a medication that is primarily eliminated through the kidneys.
Her estimated glomerular filtration rate (eGFR) has declined
significantly since her previous clinic visit. The healthcare
provider adjusts the medication dose before treatment begins.
Question Stem
What is the primary reason for reducing the medication dose?
A. Older adults absorb medications more rapidly.
B. Reduced renal function decreases drug elimination and
increases the risk of toxicity.
C. Aging prevents medications from reaching therapeutic levels.
D. Hepatic metabolism completely replaces renal drug
elimination.
Correct Answer
B. Reduced renal function decreases drug elimination and
increases the risk of toxicity.
Detailed Rationale
Many medications or their active metabolites are eliminated
through the kidneys. When renal function declines, drug
