*QUESTION 1:*
A patient is prescribed a beta-blocker for hypertension. What is the primary mechanism of action?
A) Blocking beta-adrenergic receptors, reducing heart rate and cardiac output
B) Blocking calcium channels
C) Blocking ACE
D) Blocking angiotensin II receptors
> 🎯 *CORRECT ANSWER:* A) Blocking beta-adrenergic receptors, reducing heart rate and cardiac
output
> 💡 *CLINICAL RATIONALE:*
> * *Why It's Right:* Beta-blockers reduce cardiac workload.
> * *Why Distractors Fail:* Calcium channel blockers, ACE inhibitors, and ARBs have different
mechanisms.
> * *Core Takeaway:* Beta-blockers block beta receptors.

*QUESTION 2:*
A patient is prescribed an ACE inhibitor. Which of the following is a potential adverse effect?
A) Dry cough
,B) Hypokalemia
C) Tachycardia
D) Hyperglycemia
> 🎯 *CORRECT ANSWER:* A) Dry cough
> 💡 *CLINICAL RATIONALE:*
> * *Why It's Right:* ACE inhibitors cause a dry cough.
> * *Why Distractors Fail:* ACE inhibitors cause hyperkalemia, bradycardia (not tachycardia), and do not
directly cause hyperglycemia.
> * *Core Takeaway:* ACE inhibitors can cause a dry cough.

*QUESTION 3:*
A patient is prescribed a statin. What is the primary mechanism of action?
A) HMG-CoA reductase inhibition
B) ACE inhibition
C) Beta-blockade
D) Calcium channel blockade
> 🎯 *CORRECT ANSWER:* A) HMG-CoA reductase inhibition
> 💡 *CLINICAL RATIONALE:>
> * *Why It's Right:* Statins inhibit cholesterol synthesis.
> * *Why Distractors Fail:* The other options are mechanisms of different drug classes.
> * *Core Takeaway:* Statins inhibit HMG-CoA reductase.

*QUESTION 4:*
A patient on a statin reports muscle pain. What is the nurse's priority action?
, A) Assess for rhabdomyolysis and notify the provider
B) Administer pain medication
C) Increase the statin dose
D) Ignore the complaint
> 🎯 *CORRECT ANSWER:* A) Assess for rhabdomyolysis and notify the provider
> 💡 *CLINICAL RATIONALE:*
> * *Why It's Right:* Muscle pain can indicate rhabdomyolysis.
> * *Why Distractors Fail:* Administering pain meds, increasing dose, and ignoring are not appropriate.
> * *Core Takeaway:* Muscle pain requires immediate assessment.
---
*QUESTION 5:*
A patient is prescribed warfarin. Which lab value is used to monitor therapy?
A) INR
B) aPTT
C) Platelet count
D) Hemoglobin
> 🎯 *CORRECT ANSWER:* A) INR
> 💡 *CLINICAL RATIONALE:*
> * *Why It's Right:* INR is used to monitor warfarin.
> * *Why Distractors Fail:* aPTT monitors heparin; platelet count and hemoglobin are for bleeding.
> * *Core Takeaway:* INR monitors warfarin therapy.
