SOUTH UNIVERSITY (CORRECT Q & A)
SATISFACTION GUARANTEED
1. A patient is prescribed a drug with a high volume of distribution (Vd). What does this
characteristic indicate about the drug’s behavior in the body?
A. The drug is primarily confined to the intravascular space.
B. The drug is highly protein-bound and remains in the plasma.
C. The drug is extensively distributed into tissues and body fat.
D. The drug is rapidly excreted by the kidneys.
Answer: C
Conceptual Explanation: A high volume of distribution (Vd) suggests that the drug is
lipid-soluble and leaves the blood to distribute into tissues. A low Vd indicates the drug
stays in the blood.
2. Which mechanism best explains why ACE inhibitors are frequently associated with a dry,
nonproductive cough?
A. Inhibition of Angiotensin II production in the lungs.
B. Accumulation of bradykinin and substance P in the upper airways.
,C. Direct irritation of the bronchial mucosa by the drug molecules.
D. Reflex bronchoconstriction due to systemic hypotension.
Answer: B
Conceptual Explanation: ACE (Angiotensin-Converting Enzyme) is also responsible for
the breakdown of bradykinin. Inhibiting ACE leads to bradykinin accumulation, which
sensitizes sensory nerves in the airways, causing a cough.
3. A patient taking Amiodarone for atrial fibrillation requires monitoring for which serious
adverse effect involving a specific organ system?
A. Pulmonary toxicity (fibrosis)
B. Pancreatitis
C. Acute renal failure
D. Hemolytic anemia
Answer: A
Conceptual Explanation: Amiodarone is associated with several toxicities, the most
serious being interstitial pneumonitis or pulmonary fibrosis. It also affects thyroid and liver
functions.
4. Which laboratory value is the most critical to monitor for a patient receiving long-term
treatment with Spironolactone (Aldactone)?
A. Serum sodium
, B. Serum glucose
C. Serum calcium
D. Serum potassium
Answer: D
Conceptual Explanation: Spironolactone is a potassium-sparing diuretic. The most
significant risk is hyperkalemia, which can lead to life-threatening arrhythmias.
5. A patient with Type 2 Diabetes is prescribed Metformin. The clinician must check renal
function before starting the medication because Metformin increases the risk of:
A. Rhabdomyolysis
B. Hypoglycemia
C. Nephrogenic diabetes insipidus
D. Lactic acidosis
Answer: D
Conceptual Explanation: Metformin is renally cleared. In patients with impaired renal
function, the drug can accumulate, leading to lactic acidosis, a rare but potentially fatal
condition.
6. When prescribing Levothyroxine for hypothyroidism, the patient should be instructed to
take the medication:
A. 30-60 minutes before breakfast on an empty stomach.
