π©Ί 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 β
B. Dry cough for 3 days
C. Mild dizziness on standing
D. BP 118/70 mmHg
β Correct! β A. Potassium 5.8 mEq/L
Reasoning:
ACE inhibitors cause hyperkalemia (they stop aldosterone, which normally excretes KβΊ).
A KβΊ level of 5.8 is dangerous β can cause cardiac arrhythmias.
π Nurse should hold the medication and notify provider immediately.
π‘ Normal KβΊ: 3.5β5.0 mEq/L
β€οΈ Question 2
Before giving Metoprolol, HR = 54 bpm. What is the best action?A. Give as ordered
B. Hold the dose and notify provider β
C. Recheck in 10 min
D. Give half the dose
β Correct! β B. Hold and notify provider
Reasoning:
Beta blockers lower HR and BP.
If HR < 60 bpm, donβt give it β it could cause severe bradycardia or heart block.
Always check HR and BP before administration.
π©Ί Rule: Hold if HR < 60 or SBP < 100.
π Question 3
Diabetic patient on Propranolol is at risk because this drug can:A. Increase blood glucose
B. Mask signs of hypoglycemia β
C. Increase insulin secretion
D. Cause hypoglycemia directly
β Correct! β 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.
π Question 4
Teaching ACE inhibitors: Which statement shows correct understanding?A. βIf I develop a cough, Iβll ignore it.β
B. βI need to avoid foods high in potassium.β β
C. βI can stop the medication if my BP becomes normal.β
D. βI should take salt substitutes.β
β Correct! β B. Avoid high-potassium foods
Reasoning:
ACE inhibitors retain potassium, so foods like bananas, oranges, spinach, and salt substitutes (often high in KβΊ) should be avoided.
Dry cough β not emergency, but report it later.
Never stop BP meds suddenly.
π« 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 β
D. Cold hands and feet
β Correct! β 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 β assess for crackles, edema, daily weights.
π― Score: 5 / 5 β Excellent reasoning!
Youβre connecting physiology and nursing action perfectly.
Would you like to move on to the next class β ARBs (Angiotensin II Receptor Blockers) β with the same style (teach + mini quiz)?
Perfect πͺ Letβs test everything youβve learned so far β Beta Blockers, ACE Inhibitors, ARBs, and Calcium Channel Blockers (CCBs).

π§ Cardiovascular Mixed Quiz β Answer Key & Explanations
# | Your Answer | Correct? | β
Correct Answer | π¬ Explanation |
1 | C | β
| C. HR and BP | Always check HR & BP before giving beta blockers like Metoprolol. Hold if HR < 60 bpm or SBP < 100. |
2 | B | β
| B. Notify provider / emergency care | Swelling = angioedema, a life-threatening ACE inhibitor reaction. Stop the drug and call for help. |
3 | B | β
| B. Lisinopril | ACE inhibitors block conversion of Angiotensin I β II, leading to vasodilation and β BP. |
4 | B | β
| B. Bronchoconstriction | Non-selective beta blockers like Propranolol block Ξ²β receptors β airway constriction. Contraindicated in asthma. |
5 | A | β
| A. Bananas and salt substitutes | Both contain potassium β ARBs (like Losartan) β KβΊ levels β risk of hyperkalemia. |
6 | C | β
| C. Dry cough | Caused by bradykinin buildup from ACE inhibitors β not seen with ARBs. |
7 | A | β
| A. HR 58 bpm | Verapamil slows conduction β bradycardia. Hold if HR < 60 bpm and notify provider. |

| C. Avoid grapefruit juice | Grapefruit inhibits CCB metabolism β toxicity. |
9 | B | β
| B. Hyperkalemia | Both Lisinopril (ACEI) and Spironolactone (KβΊ-sparing) increase potassium β dangerous combo β‘ |
