GRADED A+
Adrenergic Receptors & Pharmacology
Q1. Activation of which receptor leads to increased contractility,
increased heart rate, and increased renin secretion?
A) Alpha-1 receptor
B) Beta-1 receptor
C) Beta-2 receptor
D) Dopamine-1 receptor
Correct Answer: B) Beta-1 receptor
Rationale: Beta-1 receptors are primarily located in the heart and kidneys.
Their stimulation increases cardiac contractility and heart rate, and promotes
renin release from the kidneys, which is part of the sympathetic "fight or
flight" response .
Q2. Albuterol is administered during respiratory distress because it
stimulates which receptor?
A) Alpha-1
,B) Beta-1
C) Beta-2
D) Dopamine-1
Correct Answer: C) Beta-2
Rationale: Beta-2 receptors are located in the smooth muscle of the bronchi.
Stimulation of these receptors causes bronchodilation, making albuterol a
critical medication for conditions like asthma and COPD .
Q3. Norepinephrine stimulates which receptor to cause
vasoconstriction?
A) Alpha-1
B) Beta-1
C) Beta-2
D) Dopamine-1
Correct Answer: A) Alpha-1
Rationale: Alpha-1 receptors are found in vascular smooth muscle. Their
activation by norepinephrine leads to vasoconstriction, increasing systemic
vascular resistance and blood pressure .
Q4. Dopamine administered in low doses causes which effect?
A) Vasoconstriction
B) Vasodilation
C) Increased cardiac output
D) Bronchoconstriction
Correct Answer: B) Vasodilation
,Rationale: At low doses, dopamine activates Dopamine-1 receptors in the
renal and splanchnic vasculature, causing vasodilation. This effect is used to
improve renal blood flow in certain clinical situations .
Q5. Dopamine administered in high doses causes vasoconstriction
because it activates which receptor?
A) Alpha-1
B) Beta-1
C) Beta-2
D) Dopamine-1
Correct Answer: A) Alpha-1
Rationale: At higher doses, dopamine's effect shifts to predominantly
stimulating Alpha-1 receptors, leading to significant vasoconstriction and
increased blood pressure .
Cardiovascular Pathophysiology
Q6. A 45-year-old male with a history of uncontrolled hypertension,
diabetes, and CAD is at most risk for developing:
A) Heart failure
B) Asthma exacerbation
C) Gout flare
D) Hypothyroidism
Correct Answer: A) Heart failure
Rationale: Uncontrolled hypertension increases cardiac afterload, diabetes
contributes to diabetic cardiomyopathy, and CAD leads to myocardial
, ischemia. Together, these are major risk factors for the development of heart
failure .
Q7. An 84-year-old female with severe aortic stenosis undergoing hip
fracture repair is most likely to develop which postoperative
complication?
A) Myocardial infarction
B) Stroke
C) Pulmonary edema
D) Deep vein thrombosis
Correct Answer: C) Pulmonary edema
Rationale: Aortic stenosis significantly increases left ventricular afterload,
making the heart vulnerable to fluid shifts and stress. The volume shifts
associated with surgery and fracture repair can precipitate acute pulmonary
edema .
Q8. Which set of clinical manifestations is consistent with right-sided
heart failure?
A) Jugular Vein Distention and Peripheral Edema
B) Pulmonary edema and hypoxia
C) Hepatomegaly and ascites
D) Both A and C
Correct Answer: D) Both A and C
Rationale: Right-sided heart failure causes systemic venous congestion. This
manifests as jugular vein distention (JVD), peripheral edema, hepatomegaly,
and ascites due to increased venous pressure .
