Questions and Anwsers

🩺 Question 1

A nurse is reviewing lab results for a patient taking Lisinopril. Which finding requires immediate intervention?
A. Serum potassium 5.8 mEq/L ✅
B. Dry cough for 3 days
C. Mild dizziness on standing
D. BP 118/70 mmHg

✅ Correct! → A. Potassium 5.8 mEq/L

Reasoning:

ACE inhibitors cause hyperkalemia (they stop aldosterone, which normally excretes K⁺).

A K⁺ level of 5.8 is dangerous → can cause cardiac arrhythmias.

👉 Nurse should hold the medication and notify provider immediately.

💡 Normal K⁺: 3.5–5.0 mEq/L

❤️ Question 2

Before giving Metoprolol, HR = 54 bpm. What is the best action?
A. Give as ordered
B. Hold the dose and notify provider ✅
C. Recheck in 10 min
D. Give half the dose

✅ Correct! → B. Hold and notify provider

Reasoning:

Beta blockers lower HR and BP.

If HR < 60 bpm, don’t give it — it could cause severe bradycardia or heart block.

Always check HR and BP before administration.

🩺 Rule: Hold if HR < 60 or SBP < 100.

💉 Question 3

Diabetic patient on Propranolol is at risk because this drug can:
A. Increase blood glucose
B. Mask signs of hypoglycemia ✅
C. Increase insulin secretion
D. Cause hypoglycemia directly

✅ Correct! → B. Mask signs of hypoglycemia

Reasoning:

Beta blockers block SNS response (no tachycardia, tremor, sweating).

So, diabetics may not feel the warning signs of low blood sugar, leading to hypoglycemic unawareness.

💊 Question 4

Teaching ACE inhibitors: Which statement shows correct understanding?
A. “If I develop a cough, I’ll ignore it.”
B. “I need to avoid foods high in potassium.” ✅
C. “I can stop the medication if my BP becomes normal.”
D. “I should take salt substitutes.”

✅ Correct! → B. Avoid high-potassium foods

Reasoning:

ACE inhibitors retain potassium, so foods like bananas, oranges, spinach, and salt substitutes (often high in K⁺) should be avoided.

Dry cough → not emergency, but report it later.

Never stop BP meds suddenly.

🫀 Question 5

Client on Metoprolol reports which symptom should be reported immediately?
A. Mild fatigue
B. Dizziness when standing
C. Weight gain and shortness of breath ✅
D. Cold hands and feet

✅ Correct! → C. Weight gain & SOB

Reasoning:

This suggests worsening heart failure (fluid retention).

Beta blockers can sometimes worsen HF initially or indicate fluid overload.

Report immediately — assess for crackles, edema, daily weights.

A. “If I feel dizzy, I’ll take an extra dose.”

B. “I should check my pulse before each dose.”

C. “I’ll avoid grapefruit juice with this medication.”

D. “If my ankles swell, I should drink less water.”

9.

A patient taking Lisinopril and Spironolactone together is at risk for:

A. Hypokalemia

B. Hyperkalemia

C. Hyponatremia

D. Hypocalcemia

10.

Which combination of drug and side effect is matched correctly?

A. Metoprolol – tachycardia

B. Lisinopril – hypokalemia

C. Amlodipine – peripheral edema

D. Losartan – dry cough

🧠 Cardiovascular Mixed Quiz — Answer Key & Explanations

#	Your Answer	Correct?	✅ Correct Answer	💬 Explanation
1	C	✅	C. HR and BP	Always check HR & BP before giving beta blockers like Metoprolol. Hold if HR < 60 bpm or SBP < 100.
2	B	✅	B. Notify provider / emergency care	Swelling = angioedema, a life-threatening ACE inhibitor reaction. Stop the drug and call for help.
3	B	✅	B. Lisinopril	ACE inhibitors block conversion of Angiotensin I → II, leading to vasodilation and ↓ BP.
4	B	✅	B. Bronchoconstriction	Non-selective beta blockers like Propranolol block β₂ receptors → airway constriction. Contraindicated in asthma.
5	A	✅	A. Bananas and salt substitutes	Both contain potassium — ARBs (like Losartan) ↑ K⁺ levels → risk of hyperkalemia.
6	C	✅	C. Dry cough	Caused by bradykinin buildup from ACE inhibitors — not seen with ARBs.
7	A	✅	A. HR 58 bpm	Verapamil slows conduction → bradycardia. Hold if HR < 60 bpm and notify provider.
8	C	✅	C. Avoid grapefruit juice	Grapefruit inhibits CCB metabolism → toxicity.
9	B	✅	B. Hyperkalemia	Both Lisinopril (ACEI) and Spironolactone (K⁺-sparing) increase potassium → dangerous combo ⚡
10	C	✅	C. Amlodipine – Peripheral edema	Vasodilation causes fluid leakage → ankle swelling. Common with dihydropyridine CCBs.
