B) Patients may experience increased anxiety or restlessness before the antidepressant effect
occurs.

to monitor for?

8. Why are beta-blockers often used with caution in patients with uncontrolled asthma?

B) They may block beta-2 receptors, causing bronchoconstriction.
C) They trigger the release of histamine.
D) They increase sensitivity to allergens.
9. A patient presents with signs of opioid toxicity. Which drug should be immediately available for reversal?
A) Flumazenil
B) Naloxone
C) Atropine
D) N-acetylcysteine
10. What is the primary rationale for tapering long-term corticosteroid therapy?
A) To prevent rebound inflammation of the primary disease.
B) To allow the HPA axis to recover endogenous cortisol production.
C) To prevent the development of drug-induced diabetes.
D) To reduce the risk of secondary infections.
,11. A patient taking digoxin for heart failure is started on a diuretic. Which electrolyte imbalance most
significantly increases the risk of digoxin toxicity?
A) Hypercalcemia
B) Hypokalemia
C) Hypermagnesemia
D) Hyponatremia
12. When prescribing lithium to a patient, which medication class should be avoided due to the risk of
increased lithium levels and potential toxicity?
A) NSAIDs
B) Acetaminophen
C) Calcium channel blockers
D) SSRIs
13. Which of the following is the most appropriate counseling point for a patient starting levothyroxine?
A) Take with food to minimize gastric upset.
B) Take at least 30–60 minutes before breakfast on an empty stomach.
C) Avoid taking it in the morning; take it at bedtime.
D) Monitor your pulse and hold the dose if it is over 100 bpm.
14. What is a primary concern when initiating a strong CYP3A4 inhibitor in a patient already taking a
prodrug that requires activation by CYP3A4?
A) Increased risk of toxicity from the active metabolite.
B) Decreased therapeutic effect of the medication.
C) Rapid clearance of the drug from the system.
D) No clinical significance.
15. Which characteristic best qualifies a drug as a candidate for Therapeutic Drug Monitoring (TDM)?
A) A wide therapeutic index.
B) A narrow therapeutic index.
C) Extensive first-pass metabolism.
D) High protein binding affinity.
, 16. How is the pharmacokinetic profile of many oral medications typically altered in patients with chronic
liver disease?
A) Oral bioavailability is decreased due to rapid metabolism.
B) Oral bioavailability is increased due to decreased first-pass metabolism.
C) The volume of distribution is significantly reduced.
D) Renal excretion of the drug is primarily affected.
17. What is the primary clinical goal of using beta-blockers in the management of chronic heart failure?
A) Immediate reduction of preload.
B) Prevention of cardiac remodeling and improved long-term survival.
C) Acute diuresis to manage fluid overload.
D) Direct stimulation of myocardial contractility.
18. What is the clinical significance of a drug having very high plasma protein binding?
A) The drug will have a very short half-life.
B) Displacement by another highly bound drug can increase the free fraction and cause toxicity.
C) The drug cannot cross the blood-brain barrier.
D) The drug is solely excreted by the biliary system.

systemic corticosteroids?
A) Increased insulin sensitivity.
B) Increased insulin resistance and elevated blood glucose levels.
