1. A patient presents with a serum potassium level of 6.2 mEq/L. Which cardiac change is the nurse most likely to
observe on the EKG?
A. Prominent U waves
B. ST-segment depression
C. Tall, peaked T waves
D. Prolonged QT interval
🟢 C. Tall, peaked T waves
,🔴 Explanation: Hyperkalemia (potassium > 5.0 mEq/L) typically causes tall, peaked T waves and widened QRS
complexes due to altered myocardial repolarization.
2. Which regulatory body is responsible for defining the Scope of Practice for nurses within a specific state?
A. American Nurses Association (ANA)
B. State Board of Nursing
C. The Joint Commission
D. National League for Nursing
🟢 B. State Board of Nursing
🔴 Explanation: Each State Board of Nursing establishes the Nurse Practice Act, which legally defines the scope of
practice and responsibilities for nurses in that jurisdiction.
3. A nurse is preparing to administer a medication that is known to be nephrotoxic. Which laboratory value should
the nurse prioritize reviewing?
A. Serum amylase
B. Creatinine
C. Aspartate aminotransferase (AST)
D. Hemoglobin A1c
🟢 B. Creatinine
🔴 Explanation: Creatinine is a specific indicator of renal function; elevated levels suggest impaired filtration, which
increases the risk of toxicity from nephrotoxic drugs.
4. A patient is being treated for respiratory alkalosis. Which arterial blood gas (ABG) result is consistent with this
diagnosis?
A. pH 7.50, PaCO2 30 mmHg
B. pH 7.30, PaCO2 50 mmHg
,C. pH 7.48, HCO3 30 mEq/L
D. pH 7.32, HCO3 18 mEq/L
🟢 A. pH 7.50, PaCO2 30 mmHg
🔴 Explanation: Respiratory alkalosis is characterized by a high pH (>7.45) and a low PaCO2 (<35 mmHg) due to
hyperventilation.
5. Which action by the nurse is the most effective way to prevent the spread of healthcare-associated infections
(HAIs)?
A. Wearing a mask for all patient interactions
B. Routine administration of prophylactic antibiotics
C. Consistent and thorough hand hygiene
D. Restricting all visitors to the unit
🟢 C. Consistent and thorough hand hygiene
🔴 Explanation: Hand hygiene remains the primary and most effective intervention in breaking the chain of infection
and reducing the transmission of pathogens.
6. A nurse discovers a medication error was made. What is the nurse's first priority?
A. Complete an incident report
B. Notify the healthcare provider
C. Assess the patient for adverse effects
D. Inform the nurse manager
🟢 C. Assess the patient for adverse effects
🔴 Explanation: The immediate priority is patient safety; the nurse must first determine if the patient has been
harmed before proceeding with notification and documentation.
7. A patient is scheduled for surgery and expresses doubt about the procedure. The nurse notes the informed
consent is signed but the patient states, "I'm not sure why they are doing this." What is the nurse’s best action?
, A. Reassure the patient that the surgeon is highly skilled
B. Explain the risks and benefits of the surgery again
C. Notify the surgeon that the patient requires further clarification
D. Proceed with preoperative scrubbing and prep
🟢 C. Notify the surgeon that the patient requires further clarification
🔴 Explanation: It is the surgeon's legal responsibility to provide informed consent; the nurse’s role is to witness the
signature and advocate for the patient if understanding is lacking.
8. When assessing a surgical wound, the nurse notes the protrusion of internal organs through the incision.
Which term describes this occurrence?
A. Dehiscence
B. Evisceration
C. Granulation
D. Fistula
🟢 B. Evisceration
🔴 Explanation: Evisceration is a medical emergency where total separation of wound layers occurs, resulting in the
protrusion of visceral organs.
9. Which type of isolation precaution is required for a patient diagnosed with Pulmonary Tuberculosis?
A. Droplet precautions
B. Contact precautions
C. Airborne precautions
D. Protective environment
🟢 C. Airborne precautions
🔴 Explanation: Tuberculosis is transmitted via small droplets that remain suspended in the air, requiring an N95
respirator and a negative-pressure room.
