1. When assessing a patient’s radial pulse, the nurse finds it to be irregular. What is the most
appropriate next action?
A. Document the finding and notify the physician immediately.
B. Wait 15 minutes and reassess the radial pulse.
C. Measure the apical pulse for one full minute.
D. Assess the pulse on the opposite arm for comparison.
Correct Answer: C
Expert Explanation: An apical pulse is the most accurate method for assessing heart rate
when irregularities are detected. The nurse must count for a full 60 seconds to ensure any
patterns of irregularity are captured. This assessment provides a baseline for further
cardiac evaluation and medical intervention if necessary.
2. A nurse is preparing to administer an intramuscular injection to an infant. Which site is the
preferred choice for this patient population?
A. Dorsogluteal muscle
B. Ventrogluteal muscle
C. Deltoid muscle
,D. Vastus lateralis muscle
Correct Answer: D
Expert Explanation: The vastus lateralis is the preferred site for infants because it is the
most developed muscle at birth. The deltoid is often too small in infants to safely
accommodate an injection. Avoiding the dorsogluteal site is essential to prevent potential
injury to the sciatic nerve.
3. Which phase of the nursing process involves the nurse determining if the patient’s goals
and outcomes have been met?
A. Assessment
B. Evaluation
C. Implementation
D. Planning
Correct Answer: B
Expert Explanation: Evaluation is the final step where the nurse compares the patient’s
current status with the desired outcomes. During this phase, the nurse decides whether the
nursing care plan was effective or needs revision. Continuous evaluation ensures that
nursing interventions remain relevant to the patient’s changing health status.
4. The nurse is caring for a patient on contact precautions. Which personal protective
equipment (PPE) is mandatory before entering the room?
A. Mask and eye protection
, B. Gown and gloves
C. Gloves and N95 respirator
D. Gown and surgical mask
Correct Answer: B
Expert Explanation: Contact precautions are implemented to prevent the transmission of
infectious agents through direct or indirect contact. Gowns and gloves are the primary
barriers used to protect the nurse’s skin and clothing from contamination. Proper donning
and doffing of PPE are critical to maintaining a safe environment and preventing cross-
contamination.
5. A patient complains of pain level 8 out of 10. The nurse understands that this type of data
is classified as:
A. Objective data
B. Subjective data
C. Reflective data
D. Analytical data
Correct Answer: B
Expert Explanation: Subjective data consists of information provided by the patient that
cannot be independently verified by the nurse. Pain is a personal experience, and the
