NURS 103 FUNDAMENTALS OF
NURSING WEEK 10 COMPREHENSIVE
QUIZ 2026
1. A nurse is caring for a patient with a potassium level of 2.8 mEq/L. Which cardiac rhythm
change should the nurse monitor for most closely?
A. Prominent U-waves and ST-segment depression
B. Tall, peaked T-waves
C. Widened QRS complex
D. Shortened PR interval
Answer: A
Conceptual Explanation: Hypokalemia (potassium < 3.5 mEq/L) typically manifests on an
ECG as flattened T-waves, ST-segment depression, and the presence of U-waves. Tall
peaked T-waves and widened QRS complexes are characteristic of hyperkalemia.
,2. During a medication reconciliation, the nurse identifies that the patient takes Ginkgo
biloba. Which medication in the patient’s record causes the greatest concern for an
interaction?
A. Acetaminophen
B. Warfarin
C. Lisinopril
D. Metformin
Answer: B
Conceptual Explanation: Ginkgo biloba has antiplatelet properties and can increase the
risk of bleeding when taken with anticoagulants like Warfarin or antiplatelet drugs like
aspirin.
3. A patient has an arterial blood gas (ABG) result of pH 7.25, PaCO2 50 mmHg, and HCO3 24
mEq/L. How should the nurse interpret these results?
A. Respiratory acidosis
B. Respiratory alkalosis
C. Metabolic acidosis
D. Metabolic alkalosis
Answer: A
, Conceptual Explanation: A pH below 7.35 indicates acidosis. A PaCO2 above 45 mmHg
indicates a respiratory cause. Since the HCO3 is within the normal range (22-26), this is
uncompensated respiratory acidosis.
4. According to the ethical principle of Nonmaleficence, which action is required of the nurse?
A. Tell the truth to the patient at all times.
B. Avoid causing harm or hurt to the patient.
C. Fairly distribute resources among all patients.
D. Respect the patient’s right to self-determination.
Answer: B
Conceptual Explanation: Nonmaleficence is the duty to do no harm. Beneficence is doing
good; Autonomy is respecting choice; Justice is fairness; Veracity is truth-telling.
5. A nurse observes a colleague documenting a task before it is completed. Which legal tort is
most likely being violated if the documentation is found to be false?
A. Battery
B. Assault
C. Libel
D. Fraud
Answer: D
