QUESTION 1
A nurse is caring for a patient with an indwelling urinary catheter. Which
action demonstrates proper catheter care?
A) Cleanse the perineal area with soap and water daily and keep the tubing coiled
on the bed
B) Apply antibiotic ointment to the urethral meatus twice daily without cleansing
C) Ensure the catheter tubing is secured to the patient's leg or abdomen to prevent
tension and movement
D) Empty the drainage bag only when it becomes completely full to reduce the risk
of infection
E) Irrigate the catheter with normal saline solution every 4 hours to maintain
patency
✓ CORRECT ANSWER: C) Ensure the catheter tubing is secured to the patient's
leg or abdomen to prevent tension and movement
RATIONALE: Securing the catheter tubing prevents tension on the urethra, reduces
irritation, and decreases the risk of catheter displacement or tissue damage. This is
,a fundamental principle of indwelling catheter care. Option A is partially correct
(daily cleansing is appropriate), but coiling tubing on the bed creates dependent
loops that can increase infection risk. Option B is incorrect because routine
antibiotic ointment is not recommended and can promote resistant organisms.
Option D is incorrect because drainage bags should be emptied when three-
quarters full to prevent backflow and reflux of urine into the bladder. Option E is
incorrect because routine irrigation without clinical indication can introduce
infection.

QUESTION 2
A nurse is assessing a patient's nutritional status. Which finding is most
indicative of malnutrition?
A) Hemoglobin level of 13.5 g/dL
B) Serum albumin level of 2.8 g/dL
C) Total lymphocyte count of 1,800 cells/mm³
D) Prealbumin level of 22 mg/dL
E) Body mass index (BMI) of 24 kg/m²
✓ CORRECT ANSWER: B) Serum albumin level of 2.8 g/dL
RATIONALE: Serum albumin is a key indicator of nutritional status and protein
stores. Normal serum albumin ranges from 3.5-5.5 g/dL. A level of 2.8 g/dL
indicates moderate malnutrition and protein depletion. Option A shows normal
hemoglobin. Option C's lymphocyte count is on the lower end but not severely
depleted. Option D shows a normal prealbumin level (15-35 mg/dL), though
prealbumin is more sensitive to acute protein changes. Option E represents a
normal BMI (18.5-24.9 kg/m²). Serum albumin with a long half-life of 20 days is the
most reliable indicator of chronic nutritional status.

,QUESTION 3
A nurse is preparing to administer an intramuscular (IM) injection to an adult
patient. What is the appropriate needle gauge and length for a standard IM
injection?
A) 18-gauge needle, 1 inch long
B) 20-22 gauge needle, 1-1.5 inches long
C) 25-27 gauge needle, 0.5 inch long
D) 16-gauge needle, 2 inches long
E) 28-gauge needle, 0.25 inch long
✓ CORRECT ANSWER: B) 20-22 gauge needle, 1-1.5 inches long
RATIONALE: The 20-22 gauge needle with a length of 1-1.5 inches is the standard
for adult IM injections. This gauge allows adequate medication delivery while
minimizing tissue trauma, and the length ensures penetration into the muscle
tissue. Option A uses an 18-gauge which is too large and creates unnecessary tissue
damage; 18-gauge is used for IV lines. Option C with a 25-27 gauge is appropriate
for subcutaneous injections, not intramuscular. Option D with a 16-gauge is
excessively large and is used for IV access. Option E with a 28-gauge is too small
and is only appropriate for intradermal injections.

QUESTION 4
A nurse is implementing infection control measures for a patient with
suspected tuberculosis (TB). Which action is most critical?
A) Place the patient in a standard isolation room with the door open for ventilation
B) Implement airborne precautions with negative pressure room and HEPA
filtration
C) Use contact precautions with a surgical mask when entering the room
D) Require the patient to wear a surgical mask when leaving the room for tests
, E) Use droplet precautions and ensure the patient is in a private room
✓ CORRECT ANSWER: B) Implement airborne precautions with negative
pressure room and HEPA filtration
RATIONALE: Tuberculosis is transmitted via airborne nuclei and requires airborne
precautions, which include a negative pressure room that prevents contaminated
air from exiting the room, and HEPA filtration of air leaving the room. Healthcare
workers must wear N95 respirators. Option A is dangerous as an open door allows
pathogenic particles to escape. Option C (surgical mask) is insufficient for TB
protection. Option D is correct that the patient should wear a mask, but this alone
is inadequate without environmental controls. Option E describes droplet
precautions, which are appropriate for some respiratory illnesses but not TB.

QUESTION 5
A nurse is assessing pain in a patient who has limited English proficiency.
Which communication strategy is most effective?
A) Speak louder and use hand gestures to explain pain assessment
B) Use a professional medical interpreter and a pain scale with visual descriptions
C) Ask family members to translate medical terms to ensure accuracy
D) Provide written instructions in English and ask the patient to point to pain
location
E) Use technical medical terminology to ensure precise communication
✓ CORRECT ANSWER: B) Use a professional medical interpreter and a pain
scale with visual descriptions
RATIONALE: Using a professional medical interpreter ensures accurate
communication and is a standard in healthcare. Pain scales with visual descriptions
(numeric, faces, descriptive) bypass language barriers and allow patients to
communicate pain effectively. This approach respects patient autonomy and
ensures accuracy. Option A is disrespectful and ineffective; speaking louder doesn't
