, Question 1:
What is the purpose of administering vaccines?
• A) To treat existing diseases
• B) To prevent infectious diseases
• C) To alleviate symptoms of diseases
• D) To enhance the immune response
Correct Option: B
Rationale: Vaccines are specifically designed to stimulate the immune system to
produce an adaptive immune response without causing the disease, thus preventing
future infections.
Question 2:
Which of the following is a common site for intramuscular injections in adults?
• A) Subcutaneous tissue of the abdomen
• B) Deltoid muscle of the arm
• C) Gluteus maximus muscle
• D) Skin over the thigh
Correct Option: C
Rationale: The gluteus maximus is commonly used for intramuscular injections
because it is a large muscle that can accommodate larger volumes of medication and
has fewer nerves and blood vessels than other sites.
Question 3:
What is the primary reason for using a Z-track method for injections?
• A) To increase the speed of injection
• B) To prevent medication leakage into the subcutaneous tissue
• C) To minimize pain during injection
• D) To ensure the medication is absorbed faster
Correct Option: B
Rationale: The Z-track method is used to prevent the leakage of medication into the
subcutaneous tissue, which can cause irritation and staining. It involves pulling the skin
to the side before injecting, then releasing it after the injection, which seals the
medication in the muscle.
