1. What defines normal blood pressure?
A) <130/85 mmHg
B) <120/80 mmHg
C) <140/90 mmHg
D) <150/95 mmHg
✅Answer: B
Rationale: Normal BP is <120/80 mmHg per ACC/AHA guidelines.
2. Prehypertension is classified as:
A) 110-119/70-79 mmHg
B) 120-139/80-89 mmHg
C) 140-159/90-99 mmHg
D) ≥160/100 mmHg
✅Answer: B
Rationale: Prehypertension indicates elevated risk for HTN development.
3. Stage 2 hypertension is defined as:
A) 140-159/90-99 mmHg
B) ≥160/100 mmHg
C) >180/110 mmHg
D) 130-139/85-89 mmHg
✅Answer: B
Rationale: Stage 2 HTN requires aggressive management, often with 2+ medications.
4. Malignant hypertension is characterized by BP >:
A) 150/95 mmHg
B) 160/100 mmHg
,ESTUDYR
C) 180/110 mmHg
D) 200/120 mmHg
✅Answer: C
Rationale: Malignant HTN is a medical emergency with risk of end-organ damage.
5. Which symptom is NOT typical of malignant HTN?
A) Blurred vision
B) Bradycardia
C) Headache
D) Epistaxis
✅Answer: B
Rationale: Malignant HTN typically causes tachycardia, not bradycardia.
6. First-line pharmacotherapy for HTN in diabetics is:
A) Beta-blockers
B) ACE inhibitors
C) Calcium channel blockers
D) Thiazide diuretics
✅Answer: B
Rationale: ACEIs (e.g., lisinopril) are renal-protective in diabetics.
7. A patient on lisinopril reports a dry cough. The nurse should:
A) Recommend cough syrup
B) Notify the provider (possible ACEI side effect)
C) Increase fluid intake
D) Continue monitoring
✅Answer: B
Rationale: Dry cough occurs in 5-20% on ACEIs due to bradykinin accumulation.
8. Which medication is an ARB?
, ESTUDYR
A) Metoprolol
B) Losartan
C) Amlodipine
D) Furosemide
✅Answer: B
Rationale: ARBs (e.g., losartan) block angiotensin II receptors without causing cough.
9. Raynaud’s disease patient education includes:
A) Smoking cessation and cold avoidance
B) High-intensity exercise
C) Increased caffeine intake
D) Tight clothing
✅Answer: A
Rationale: Vasospasm triggers (cold, stress, smoking) must be avoided.
10. Classic PAD symptom is:
A) Intermittent claudication
B) Chest pain at rest
C) Bilateral hand swelling
D) Persistent headache
✅Answer: A
Rationale: Calf pain during activity that resolves with rest is hallmark of PAD.
11. Post-op femoral bypass graft care includes monitoring for:
A) Cold, pale extremity (occlusion sign)
B) Mild edema (expected)
C) Throbbing pain (normal)
D) All of the above
✅Answer: D
Rationale: Edema/throbbing are normal; coldness indicates graft failure.
12. DVT risk factors include all EXCEPT:
