Questions & Comprehensive Explanations:
Cardiovascular & Respiratory Health
1. If your patient is in the catarrhal stage of pertussis, upon examination, what would you find?
A. Paroxysmal coughing with inspiratory "whoop" B. Post-tussive vomiting C. Mild upper respiratory
symptoms with cough, indistinguishable from a common cold D. Cyanosis and apnea
Correct Answer: C. Mild upper respiratory symptoms with cough, indistinguishable from a
common cold.
Expert Rationale: The catarrhal stage of pertussis (whooping cough) is the initial phase,
characterized by mild, non-specific upper respiratory symptoms like a runny nose, sneezing, low-
grade fever, and a mild cough. It's often mistaken for a common cold because the characteristic
"whooping" cough, post-tussive vomiting, and severe respiratory distress associated with pertussis don't
typically develop until the subsequent paroxysmal stage.
,2. What would NOT be considered a typical finding in a geriatric patient? A. Thinner epidermis,
dermis, and subcutaneous layers of skin B. Bright purple-colored patches on the forearms and hands
(senile purpura) C. Opaque white ring at the periphery of the cornea (arcus senilis) D. Low frequency
hearing loss
Correct Answer: D. Low frequency hearing loss.
Expert Rationale: While hearing loss is common in geriatrics, the typical age-related hearing loss is
presbycusis, which primarily affects high-frequency sounds. This is due to degenerative changes in
the inner ear structures. Low-frequency hearing loss is less common and would warrant further
investigation for other causes. The other options (thinner skin, senile purpura, arcus senilis) are all
common and expected age-related changes.
3. Which of the following are typical findings in a geriatric patient? A. Thinner epidermis, dermis,
and subcutaneous layers of skin, bright purple-colored patches on the forearms and hands, opaque white
ring at the periphery of the cornea B. Increased skin elasticity, decreased incidence of senile purpura,
clear corneal periphery C. Thicker epidermis, increased melanin production, absence of arcus senilis D.
Normal skin thickness, no purpura, absence of corneal rings
Correct Answer: A. Thinner epidermis, dermis and subcutaneous layers of skin, bright purple-
colored patches on the forearms and hands, opaque white ring at the periphery of the cornea.
Expert Rationale: As we age, the skin undergoes several changes, including thinning of its layers,
leading to increased fragility and susceptibility to bruising (senile purpura). Arcus senilis, a benign
opaque white ring around the cornea, is also a common age-related finding due to lipid deposits. These
are all expected physiological changes in a geriatric patient.
4. What are the risk factors for age-related macular degeneration? A. High blood pressure,
diabetes, obesity, and lack of exercise B. Tobacco use, aging, sun exposure, and family history C. Low
cholesterol, antioxidant-rich diet, regular eye exams D. Childhood infections, autoimmune disorders,
and genetic mutations unrelated to family history
Correct Answer: B. Tobacco use, aging, sun exposure and family history.
Expert Rationale: The primary modifiable risk factor for age-related macular degeneration (AMD) is
tobacco use. Non-modifiable risk factors include aging (the incidence increases significantly with age),
sun exposure (particularly UV light), and a family history of AMD, indicating a genetic
predisposition.

5. What is considered an underweight BMI? A. < 18.5 B. 18.5-24.9 C. 25-29.9 D. 30-39.9
Correct Answer: A. < 18.5.
Expert Rationale: Body Mass Index (BMI) categorizes weight status. A BMI of less than 18.5 is
classified as underweight.
6. What is considered a normal BMI? A. < 18.5 B. 18.5-24.9 C. 25-29.9 D. 30-39.9
Correct Answer: B. 18.5-24.9.
Expert Rationale: A BMI between 18.5 and 24.9 falls within the healthy or normal weight range,
indicating an appropriate weight for height.
7. What is considered an overweight BMI? A. < 18.5 B. 18.5-24.9 C. 25-29.9 D. 30-39.9
Correct Answer: C. 25-29.9.
Expert Rationale: A BMI between 25 and 29.9 is classified as overweight, indicating a weight that is
higher than what is considered healthy for a given height.
8. What is considered an obese BMI? A. 25-29.9 B. 30-39.9 C. 40-49.9 D. > 40
Correct Answer: B. 30-39.9.
Expert Rationale: A BMI between 30 and 39.9 is categorized as obese, signifying a significant
amount of excess body fat that can lead to health problems.
9. What is considered a grossly obese BMI? A. 30-39.9 B. 40-49.9 C. > 40 D. > 50
Correct Answer: C. > 40.
, Expert Rationale: A BMI of 40 or greater is considered grossly obese (also sometimes referred to as
morbidly obese or extreme obesity), indicating a very high level of excess body fat that poses
substantial health risks.
10. Which drugs are classified under Pregnancy Category A? A. Acetaminophen and ibuprofen B.
Penicillins and cephalosporins C. Vitamins and levothyroxine D. Azithromycin and erythromycin
Correct Answer: C. Vitamins and levothyroxine.
Expert Rationale: Pregnancy Category A drugs have been studied in pregnant women and have shown
no evidence of risk to the fetus in any trimester. Common examples include most vitamins (especially
prenatal vitamins with folic acid) and levothyroxine (thyroid hormone replacement), which is often
essential for maternal and fetal health.
11. Which drugs are classified under Pregnancy Category B? A. Warfarin and isotretinoin B. ACE
inhibitors and benzodiazepines C. Acetaminophen, ibuprofen, penicillins, cephalosporins,
azithromycin, and erythromycin D. Chemotherapy agents and thalidomide
Correct Answer: C. Acetaminophen, ibuprofen, penicillins, cephalosporins, and azithromycin
and erythromycin antibiotics.
Expert Rationale: Pregnancy Category B drugs are those for which animal studies have shown no
risk, but human studies are either lacking or inadequate, or animal studies showed minor risks but
human studies did not. Many commonly used medications fall into this category, including
acetaminophen, ibuprofen (especially early in pregnancy), penicillins, cephalosporins,
azithromycin, and erythromycin.
12. A geriatric patient who has a 40 pack-year smoking history complains of painful cramping in
the leg muscles that occurs after walking for 20 minutes. After taking a complete history and
performing a physical exam, what is the most likely diagnosis? A. Deep Vein Thrombosis (DVT) B.
Sciatica C. Intermittent Claudication D. Peripheral Neuropathy
Correct Answer: C. Intermittent Claudication.
Expert Rationale: This classic presentation of intermittent claudication is highly suggestive of
Peripheral Artery Disease (PAD). The key features are activity-induced muscle pain (claudication)
that is consistently relieved by rest. Smoking is a significant risk factor for PAD. While other options
