Correct Answers and Expert Explanation for Each
Question | Chamberlain
1. Which of the following is considered the first-line pharmacologic agent for the
treatment of Type 2 Diabetes Mellitus according to ADA guidelines?
A. Glyburide
B. Metformin
C. Sitagliptin
D. Pioglitazone
Correct Answer: B
Expert Explanation: Metformin is the preferred initial medication due to its
efficacy, safety, and low cost. It works primarily by decreasing hepatic glucose
production and improving insulin sensitivity in peripheral tissues. Clinical evidence
strongly supports its role in reducing A1C levels and improving cardiovascular
outcomes without causing weight gain.
2. When should a patient be instructed to take their daily dose of Levothyroxine
(Synthroid)?
A. With a high-fiber breakfast
,B. At bedtime with a snack
C. Immediately following the largest meal of the day
D. In the morning on an empty stomach
Correct Answer: D
Expert Explanation: Levothyroxine absorption is most effective when taken on an
empty stomach, ideally 30 to 60 minutes before breakfast. Food, particularly those
high in fiber or calcium, can significantly impair the drug’s bioavailability.
Consistent timing is also essential to maintain stable thyroid-stimulating hormone
levels in the blood.
3. A patient with asthma is prescribed a Short-Acting Beta-Agonist (SABA) for rescue
use. What is the primary mechanism of action for this drug class?
A. Relaxing bronchial smooth muscle
B. Reducing airway inflammation
C. Blocking leukotriene receptors
D. Inhibiting mast cell degranulation
Correct Answer: A
Expert Explanation: SABAs like albuterol stimulate beta-2 adrenergic receptors,
leading to the relaxation of bronchial smooth muscle and rapid bronchodilation.
,These medications are intended for quick relief of acute symptoms rather than long-
term control of underlying inflammation. Patients should be monitored for
frequency of use, as high usage indicates poorly controlled asthma.
4. In patients using Inhaled Corticosteroids (ICS) for asthma management, which
education point is most critical to prevent oral candidiasis?
A. Taking the medication with food
B. Using a spacer and rinsing the mouth after use
C. Limiting water intake after inhalation
D. Increasing the dose during a cold
Correct Answer: B
Expert Explanation: Rinsing the mouth and gargling with water after ICS use helps
remove residual medication from the oropharynx, reducing the risk of fungal
infections. Using a spacer device also improves drug delivery to the lungs while
minimizing deposition in the mouth. Consistent adherence to these practices is vital
for long-term respiratory health and comfort.
5. Which of the following contraindications is most significant for the use of Combined
Oral Contraceptives (COCs)?
A. Age under 18 years
B. Occasional tension headaches
, C. Smoking in women over age 35
D. History of dysmenorrhea
Correct Answer: C
Expert Explanation: Combined oral contraceptives significantly increase the risk of
serious cardiovascular events, such as myocardial infarction and stroke, in smokers
over 35. The estrogen component is primarily responsible for this increased risk of
thromboembolism. In these patients, progestin-only methods or non-hormonal
options are safer alternatives.
6. Which laboratory value is used to monitor the therapeutic effect of Warfarin
(Coumadin)?
A. International Normalized Ratio (INR)
B. Activated Partial Thromboplastin Time (aPTT)
C. Glycated Hemoglobin (A1C)
D. Serum Creatinine
Correct Answer: A
Expert Explanation: The INR is the standardized measurement used to assess the
extrinsic pathway of coagulation affected by Warfarin. For most patients, a target
therapeutic INR range is between 2.0 and 3.0. Frequent monitoring is necessary
