1. What is the correct sequence for donning personal protective equipment
(PPE)?
a) Gloves, gown, mask, goggles
b) Gown, mask, goggles, gloves
c) Mask, gown, gloves, goggles
d) Gown, gloves, mask, goggles
ANS>>: b) Gown, mask, goggles, gloves
Rationale: The correct order to don PPE is gown first to cover clothing, then
mask or respirator, goggles or face shield, and finally gloves to ensure all
protective barriers are in place before patient contact.
2. When performing hand hygiene using an alcohol-based hand rub, how long
should you rub your hands?
a) 10 seconds
b) 15 seconds
,c) 20 seconds
d) 30 seconds
ANS>>: c) 20 seconds
Rationale: The CDC recommends rubbing hands with an alcohol-based hand rub
for at least 20 seconds to ensure effective microbial killing.
3. Which site is preferred for adult intramuscular (IM) injections?
a) Deltoid muscle
b) Vastus lateralis
c) Ventrogluteal site
d) Dorsogluteal site
ANS>>: c) Ventrogluteal site
Rationale: The ventrogluteal site is preferred because it is away from major
nerves and blood vessels, providing a safer injection site with less risk of injury.
4. What is the appropriate angle for inserting a needle during a subcutaneous
injection?
a) 15 degrees
b) 45 degrees
c) 60 degrees
d) 90 degrees
ANS>>: b) 45 degrees

6. What is the correct technique to measure a patient's blood pressure
manually?
a) Inflate cuff until pulse disappears, then slowly deflate
b) Inflate cuff until 20 mmHg above the point where pulse disappears, then slowly
deflate
c) Inflate cuff to 180 mmHg, then slowly deflate
d) Inflate cuff to 150 mmHg, then quickly deflate
ANS>>: b) Inflate cuff until 20 mmHg above the point where pulse disappears,
then slowly deflate
Rationale: Inflating the cuff 20–30 mmHg above the disappearance of the radial
pulse ensures you capture the true systolic pressure without missing it.
