*SECTION ONE: QUESTIONS 1–100*
1. A patient presents with a suspected drug-induced
hypersensitivity reaction. Which immunoglobulin is
primarily responsible for an immediate Type I
hypersensitivity response?
,A. IgG
B. IgM
C. IgE
D. IgA
🟢 C. IgE
🔴 Explanation: Type I hypersensitivity reactions are
mediated by IgE antibodies which bind to mast cells and
basophils, triggering the release of histamine and other
inflammatory mediators.
2. Which of the following pharmacokinetic parameters
describes the volume of plasma from which a drug
is completely removed per unit of time?
A. Bioavailability
B. Clearance
C. Half-life
D. Volume of distribution
🟢 B. Clearance
, 🔴 Explanation: Clearance is a measure of the body's
ability to eliminate a drug, representing the volume of
fluid cleared of the drug over a specific time period.
3. Under the principles of medical ethics,
"beneficence" is defined as:
A. The duty to do no harm
B. Respecting the patient's right to self-determination
C. The obligation to act in the best interest of the patient
D. Ensuring fairness in the distribution of resources
🟢 C. The obligation to act in the best interest of the
patient
🔴 Explanation: Beneficence requires healthcare
providers to take positive actions to help others and act
in a way that provides benefit to the patient.
4. A 65-year-old male with a history of heart failure is
