Which of the following is an intervention study?
A) Cohort B) Ecological C) Case-Control D) Randomized Clinical Trial
Correct answer: D) Randomized Clinical Trial (RCT)
A randomized clinical trial is an interventional study because the researcher actively assigns participants to an intervention or treatment and then evaluates the outcomes.
A) Cohort → Observational study; researchers observe exposure and outcomes.
B) Ecological → Observational study using population-level data.
C) Case-control → Observational study; compares previous exposures between cases and controls.
D) Randomized Clinical Trial → ✅ Interventional study; participants are randomly assigned to intervention/control groups.
🧠 Exam tip: Interventional = researcher assigns the intervention → RCT.
Which of the following local organization's primary mission is to the safety and quality of healthcare in health institution?
A) Saudi central board for accreditation of healthcare institutions (CBAHI)
B) Saudi Commission for Health Specialties (SCFHS)
C) Saudi Food and Drug Authority (SFDA)
D) Saudi pharmaceutical Society (SPS)
Correct answer: A) Saudi Central Board for Accreditation of Healthcare Institutions (CBAHI)
CBAHI is the Saudi organization specifically focused on healthcare quality and patient safety in healthcare facilities. Its mission is to support healthcare facilities through accreditation and ensure continuous compliance with quality and patient-safety standards.
Why the others are incorrect:
B) SCFHS → Primarily regulates and develops healthcare professionals, including professional registration, training, examinations, and practice standards.
C) SFDA → Regulates medicines, medical devices, food, and related products, rather than accrediting healthcare institutions.
D) Saudi Pharmaceutical Society (SPS) → A professional organization concerned with the pharmacy profession, not accreditation of healthcare facilities.
🧠 Exam tip: CBAHI → Accreditation + Healthcare facility quality + Patient safety.
Which of the following is most likely to inhibit lactation?
A) Prolactin B)Progesterone C) Growth hormone D)Chorionic somatomammotropin
The correct option is B) Progesterone.
Why Progesterone Inhibits Lactation:
During pregnancy, levels of prolactin (the primary hormone responsible for milk production) increase steadily. However, actual milk secretion (lactogenesis II) is inhibited during pregnancy by high circulating levels of progesterone and estrogen, which are secreted by the placenta.
Progesterone directly blocks prolactin receptors on alveolar cells in the breast, preventing full milk production and secretion.
After delivery, the placenta is expelled, causing a sudden and rapid drop in progesterone (and estrogen) levels. This loss of progesterone inhibition, while prolactin levels remain elevated, allows active lactation to begin.
Role of the Other Hormones:
Prolactin: Directly promotes milk synthesis and secretion (lactogenesis).
Growth Hormone: Promotes mammary gland development and supports milk production by enhancing nutrient availability.
Chorionic Somatomammotropin (Human Placental Lactogen - hPL): Supports mammary gland growth and development during pregnancy in preparation for lactation, rather than inhibiting it.
🧠 Exam pearl
High progesterone during pregnancy → inhibits milk secretion.
After delivery: ↓ progesterone + prolactin → lactation begins.
Which of the following is the definition of management?
A) The art of maximizing profitability
B) The art of maximizing productivity
C)The art of maximizing possibilities
D)The art of maximizing predictability
The correct option is C) The art of maximizing possibilities.
Explanation
While management involves profitability, productivity, and predictability, its broader and more comprehensive definition—frequently referenced in organizational behavior, leadership, and management theory (such as Mary Parker Follett's modern framing of management)—is "the art of maximizing possibilities."
Management is fundamentally about leveraging resources, human capital, and strategic opportunities to unlock potential and create outcomes that would not otherwise occur automatically.
Why the others are incorrect:
A) Maximizing profitability → A business objective, not the definition of management.
B) Maximizing productivity → ✅ Closest to the standard management concept.
C) Maximizing possibilities → Not a standard definition.
D) Maximizing predictability → Not a standard definition.
📌 Exam tip:
Management → achieving goals efficiently + effectively → maximizing productivity.
A 28-year-old woman was recently diagnosed with Crohn’ was started with high dose intravenous corticosteroids. She converted to oral drugs and was started on infliximab, a tumour factor ꭤ(TNf-ꭤ), inhibitor.
Which of the following tests should be performed prior to infliximab?
A) HIV screening
B) Influenza screening
C) Hepatitis C screening
D)Tuberculosis screening
The correct option is D) Tuberculosis screening.
Why Tuberculosis Screening is Required:
Infliximab is a tumor necrosis factor-alpha (TNF-alpha) inhibitor. TNF-alpha plays a crucial role in forming and maintaining granulomas, which keep latent tuberculosis infection (LTBI) sequestered and dormant. Blocking TNF-alpha can cause granulomas to break down, leading to the reactivation of latent TB, which can cause severe or disseminated disease. Therefore, all patients must be screened for latent or active TB (via a tuberculin skin test [TST] or interferon-gamma release assay [IGRA]) and treated if positive before starting infliximab therapy.
Key Pre-Infliximab Screening Guidelines
Tuberculosis (TB) Screening: Mandatory prior to initiating therapy (TST/IGRA, chest X-ray if indicated).
Hepatitis B Screening: Mandatory prior to initiating therapy (HBsAg and anti-HBc) due to the risk of severe Hepatitis B reactivation.
Hepatitis C / HIV Screening: Not routinely required as a mandatory screening protocol prior to TNF inhibitor initiation unless specific risk factors or clinical indications exist.
Influenza: Patients should receive updated non-live vaccines (like the inactivated flu shot) before starting therapy, but routine "screening" for influenza is not required.
Board-exam memory aid: Infliximab → “TB before TNF blockade.”
Other important pre-treatment assessments can include hepatitis B screening, CBC and liver-function assessment, but among the choices given, TB is the clear answer.
A pharmacist working in inpatient pharmacy received a request pharmacy and therapeutic (P&T) committee to evaluate a medicine included in the hospital formulary. The requester wants to have the value in a monetary value(dollar value)
Which of the following pharmacoeconomic tools will the pharmacy use to answer the request?
A) Cost-utility analysis
B) Cost-benefit analysis
C) Cost-minimization analysis
D) Cost-effectiveness analysis
Correct answer: B) Cost-benefit analysis (CBA)
The key phrase is “value in a monetary value (dollar value)”.
Cost-benefit analysis (CBA): Both costs and outcomes/benefits are expressed in monetary terms (e.g., dollars).
Cost-effectiveness analysis (CEA): Outcomes are measured in natural clinical units (e.g., life-years gained, cases prevented).
Cost-utility analysis (CUA): Outcomes are usually measured as QALYs or DALYs.
Cost-minimization analysis (CMA): Used when the alternatives have equivalent clinical outcomes, so only costs are compared.
Exam tip: If the question says “monetary value/dollars” → Cost-benefit analysis (CBA).
