Question 1
What is the proportion of the population affected by a disease at a specific point in
time?
A. Incidence rate
B. Prevalence rate
C. Mortality rate
D. Morbidity rate
B. Prevalence rate
Rationale: Prevalence rate measures the total number of cases of a disease existing
in a population at a given time, aiding in resource allocation for chronic conditions.
This informs pharmacological planning for ongoing therapies, ensuring patient
safety by anticipating community-wide needs.
,Question 2
What is the first-line medication for the treatment of migraines?
A. Sumatriptan
B. Acetaminophen
C. Ibuprofen
D. Propranolol
C. Ibuprofen
Rationale: NSAIDs like ibuprofen are first-line for acute migraines due to their
anti-inflammatory and analgesic effects via COX inhibition, reducing
prostaglandin synthesis. Nursing considerations include monitoring for GI bleeding
in at-risk patients to enhance safety.
Question 3
What organ does cystic fibrosis primarily affect, leading to pharmacological
interventions?
A. Liver
B. Pancreas
C. Kidneys
D. Brain
B. Pancreas
Rationale: Cystic fibrosis causes thick mucus in the pancreas, impairing enzyme
secretion and leading to malabsorption; drugs like pancreatic enzymes are used.
Adverse effects include GI upset, so nurses monitor digestion and adjust dosing for
safety.
Question 4
What causes Addison's disease, influencing glucocorticoid replacement therapy?
A. Excess cortisol
B. Decreased glucocorticoids due to adrenal cortex destruction
C. Overproduction of thyroid hormone
, D. Insulin resistance
B. Decreased glucocorticoids due to adrenal cortex destruction
Rationale: Autoimmune destruction reduces cortisol, requiring hydrocortisone
replacement. Mechanism mimics natural glucocorticoids; nurses watch for adrenal
crisis (hypotension) and teach stress dosing to prevent life-threatening adverse
events.
Question 5
Which hospitalized patient is at highest risk for developing delirium?
A. A young adult with pneumonia
B. An elderly male with COVID-19
C. A middle-aged female with diabetes
D. A child with asthma
B. An elderly male with COVID-19
Rationale: Elderly patients with infections like COVID-19 face multifactorial
risks (e.g., hypoxia, medications). Nursing considerations include minimizing
sedatives (e.g., benzodiazepines) to avoid exacerbating cognitive adverse effects.
Question 6
What is the gold standard for diagnosing celiac disease?
A. Blood glucose test
B. Endoscopy with small intestine biopsy
C. MRI scan
D. Urinalysis
B. Endoscopy with small intestine biopsy
Rationale: Biopsy confirms villous atrophy from gluten intolerance; gluten-free
diet is primary, but drugs like steroids manage refractory cases. Nurses educate on
avoiding cross-contamination to prevent adverse GI effects.
