Rationale: A blood pressure of 120/80 mmHg is considered the standard normal reading
for adults.
Question 6: At what angle should an intramuscular injection be administered?
A. 15 degrees B. 45 degrees C. 60 degrees D. 90 degrees
,CORRECT ANSWER: D. 90 degrees
Rationale: Intramuscular injections are administered at a 90-degree angle to ensure the
medication reaches the muscle tissue.
Question 7: At what angle is a subcutaneous injection typically administered?
A. 15 degrees B. 45 degrees C. 60 degrees D. 90 degrees
CORRECT ANSWER: B. 45 degrees
Rationale: Subcutaneous injections are typically given at a 45-degree angle, or 90
degrees depending on needle length and tissue fold.
Question 8: At what angle should an intradermal injection be administered?
A. 5 to 15 degrees B. 30 to 40 degrees C. 45 to 60 degrees D. 90 degrees
CORRECT ANSWER: A. 5 to 15 degrees
Rationale: Intradermal injections are given at a shallow 5 to 15-degree angle to place
the medication just under the epidermis.
Question 9: What is the primary purpose of the Z-track method for intramuscular
injections?
A. To increase absorption rate B. To prevent leakage into subcutaneous tissue C. To
reduce pain during insertion D. To prevent hitting a blood vessel
CORRECT ANSWER: B. To prevent leakage into subcutaneous tissue
Rationale: The Z-track method seals the medication in the muscle and prevents it from
leaking into irritating subcutaneous tissues.
Question 10: Which position is best for a patient experiencing severe dyspnea?
A. Supine B. Prone C. Trendelenburg D. High Fowler's
CORRECT ANSWER: D. High Fowler's
Rationale: High Fowler's position promotes maximum lung expansion and eases the
work of breathing.
Question 11: Which position is most appropriate for a patient with orthopnea?
A. Supine B. Orthopneic C. Lateral D. Sims'
CORRECT ANSWER: B. Orthopneic
Rationale: The orthopneic position allows the patient to sit upright and lean forward
over a bed table, maximizing chest expansion.
Question 12: Which position is indicated for a patient experiencing shock?
A. High Fowler's B. Modified Trendelenburg C. Knee-chest D. Lithotomy
,CORRECT ANSWER: B. Modified Trendelenburg
Rationale: Modified Trendelenburg elevates the legs to promote venous return to the
heart and vital organs.
Question 13: What is the preferred position for a lumbar puncture?
A. Prone B. Supine C. Lateral recumbent D. High Fowler's
CORRECT ANSWER: C. Lateral recumbent
Rationale: The lateral recumbent position with knees drawn to the chest flexes the spine
and widens the intervertebral spaces.
Question 14: Which position is best for administering a cleansing enema?
A. Supine B. Prone C. Left lateral Sims' D. Right lateral
CORRECT ANSWER: C. Left lateral Sims'
Rationale: The left lateral Sims' position follows the natural anatomical curve of the
sigmoid colon for fluid flow.
Question 15: What is the recommended duration for routine hand hygiene with
soap and water?
A. 1 to 5 seconds B. 5 to 10 seconds C. 15 to 20 seconds D. 60 to 120 seconds
CORRECT ANSWER: C. 15 to 20 seconds
Rationale: Vigorous rubbing for at least 15 to 20 seconds is required to effectively
remove transient flora.
Question 16: What is the first piece of personal protective equipment (PPE) to be
removed?
A. Gown B. Mask C. Goggles D. Gloves
CORRECT ANSWER: D. Gloves
Rationale: Gloves are the most contaminated and should be removed first to prevent
cross-contamination.
Question 17: Which type of mask is required for airborne precautions?
A. Surgical mask B. N95 respirator C. Face shield D. Cloth mask
CORRECT ANSWER: B. N95 respirator
Rationale: An N95 respirator filters out at least 95% of airborne particles, protecting
against diseases like tuberculosis.
Question 18: What is the minimum distance required for droplet precautions?
A. 1 foot B. 3 feet C. 6 feet D. 10 feet
, CORRECT ANSWER: B. 3 feet
Rationale: Droplet precautions require a mask when working within 3 feet of the patient,
as droplets do not travel far.
