200 Verified Practice Questions with Answers & Rationales
.
Part 1: Safety & Infection Control (Questions 1-30)
Question 1: A nurse is performing eye irrigation for a client who was exposed to
smoke and ash. Which of the following actions should the nurse take?
A. Hold the irrigator 1.25 cm (0.5 in) above the eye
B. Direct the irrigation solution upward toward the upper eyelid
C. Exert pressure on the bony prominences when holding the eyelid open
D. Direct the irrigation from the outer canthus to the inner canthus of the eye
Answer: C. Exert pressure on the bony prominences when holding the eyelid open
Rationale: The nurse should hold the upper lid against the eyebrow and the lower
lid against the cheekbone (bony prominences) when irrigating the eye to provide
stability and prevent injury .
Why the other options are incorrect:
,A: The irrigator should be held 2.5 cm (1 in) above the eye, not 1.25 cm, to
prevent touching the eye.
B: Irrigation should be directed onto the lower conjunctival sac, not upward, to
prevent corneal injury.
D: Irrigation should flow from the inner canthus to the outer canthus to prevent
contaminated fluid from entering the nasolacrimal duct.
Question 2: A nurse is preparing to remove an NG tube for a client who had a
partial colectomy. Which action should the nurse take?
A. Maintain suction while removing the NG tube
B. Instill 100 mL of air into the NG tube before removal
C. Pinch the NG tube while removing the tube
D. Instruct the client to breathe in and out during removal
Answer: C. Pinch the NG tube while removing the tube
,Rationale: The nurse should pinch the NG tube during removal to decrease the
risk of aspiration of any gastric contents. Pinching closes the tube lumen,
preventing drainage from entering the pharynx during withdrawal .
Why the other options are incorrect:
A: Suction should be disconnected before removal to decrease injury to the
gastrointestinal mucosa.
B: The nurse should instill 50 mL of air (not 100 mL) to clear gastric drainage.
D: The client should take a deep breath and hold it during removal to close off the
glottis.
Question 3: A nurse is preparing to administer an intramuscular injection to a
client who is overweight. Which site should the nurse select?
A. The lower, medial quadrant of the buttock near the coccyx
B. The side hip between the iliac crest and the anterior iliac spine
C. The tissue of the posterior upper arm
, D. The lower, inner thigh 4 finger widths above the patella
Answer: B. The side hip between the iliac crest and the anterior iliac spine
Rationale: The side hip between the iliac crest and anterior iliac spine forms the
boundaries for the ventrogluteal injection site. This is the preferred site for IM
injections in adults because it has no major nerves or blood vessels .
Why the other options are incorrect:
A: The dorsogluteal site (near the coccyx) risks sciatic nerve injury.
C: The deltoid (posterior upper arm) is limited to 1 mL of medication.
D: The vastus lateralis (lower, inner thigh) is appropriate but requires locating 4
finger widths below the greater trochanter, not above the patella.
Question 4: A nurse is preparing to insert an indwelling urinary catheter. Which
technique should be used?
