Ligands) Format: Single Best Answer (SBA), application questions and map mechanism
Practice Questions
1. A 68-year-old male with a history of benign prostatic hyperplasia (BPH) and hypertension is
prescribed Tamsulosin. Which receptor subtype is specifically targeted to improve urinary flow
while minimizing systemic hypotension?
A. Alpha-1A receptors
B. Alpha-1B receptors
C. Alpha-2 receptors
D. Beta-1 receptors
2. A patient in the emergency department is experiencing anaphylactic shock. Epinephrine is
administered intramuscularly. Which receptor activation is primarily responsible for reversing
the life-threatening hypotension associated with this condition?
A. Beta-2 receptors
B. Alpha-1 receptors
C. Muscarinic M3 receptors
D. Beta-1 receptors
3. During a routine eye examination, a clinician applies a drug to induce mydriasis (pupil dilation)
without affecting cycloplegia (accommodation). This drug most likely acts as an agonist at which
receptor?
A. Alpha-1 receptors
B. Beta-2 receptors
C. Muscarinic M3 receptors
D. Nicotinic receptors
4. A 25-year-old female with exercise-induced asthma uses a Salbutamol (Albuterol) inhaler. She
later complains of "shaky hands." This side effect is caused by the stimulation of which receptors
in the skeletal muscle?
