Question

A nurse is caring for a client with chest pain who suddenly becomes unresponsive. The client is pulseless, and apneic. The code team places the client on the monitor which indicates ventricular fibrillation, what is the next priority action?

Answer 1

Correct Answers:

Defibrillation

Rationale :

🔸When a client becomes pulseless and apneic, and the monitor shows ventricular fibrillation (V-fib), the immediate priority intervention is defibrillation.

🔸V-fib is a lethal arrhythmia characterized by disorganized electrical activity resulting in no effective cardiac output.

🔸It requires immediate unsynchronized defibrillation to restore a perfusing rhythm.

🔸CPR should begin while the defibrillator is being prepared, but defibrillation is the definitive treatment.

🔸Medications like epinephrine and amiodarone are supportive but follow defibrillation per Advanced Cardiac Life Support (ACLS) protocol.

🔸 Synchronized cardioversion is not appropriate for V-fib as there is no detectable R wave to sync with.

Answer 2

Correct Answers:

Obstructive sleep apnea (OSA)

Rationale :

🔸Obstructive sleep apnea (OSA) is a recognized independent risk factor for the development of hypertension.

🔸During apneic episodes, oxygen saturation drops, triggering sympathetic nervous system activation, which leads to vasoconstriction and elevated blood pressure over time.

🔸OSA is often underdiagnosed and contributes to resistant hypertension.

🔸In contrast, a high HDL level (≥60–70 mg/dL) and regular exercise are protective factors, and benazepril is an ACE inhibitor used to treat hypertension, not cause it.

Answer 3

Correct Answers:

IV Nitroglycerine

Rationale :

🔸IV nitroglycerine is a potent vasodilator that acts directly on vascular smooth muscle, leading to dilation of coronary arteries and reduction of myocardial oxygen demand.

🔸It is commonly used in the setting of acute myocardial infarction (AMI) to improve blood flow and relieve ischemic chest pain.

🔸While alteplase is used for clot dissolution and heparin for anticoagulation, they do not cause coronary vasodilation.

🔸Metoprolol reduces heart rate and contractility, not vessel dilation.

Answer 4

Correct Answers:

Hypokalemia

Rationale :

🔹Furosemide (Lasix) is a loop diuretic that promotes the excretion of sodium, chloride, and potassium in the loop of Henle.

🔹The patient is receiving a higher dose IV than at home, which increases the risk of hypokalemia.

🔹This condition may lead to muscle weakness, arrhythmias, and ECG changes, especially in clients with heart failure.

🔹Monitoring potassium levels and providing supplements if needed is essential. The drug does not cause hyperkalemia, hypernatremia, or hypocalcemia under normal conditions.

Answer 5

Correct Answers:

Obtain a 12-lead ECG

Rationale :

🔸A potassium level of 6.8 mEq/L indicates severe hyperkalemia, which can lead to life-threatening cardiac arrhythmias such as ventricular fibrillation or asystole.

🔸The priority action is to obtain a 12-lead ECG to assess for characteristic changes, including peaked T-waves, widened QRS complex, or bradyarrhythmias.

🔸These changes guide the urgency of treatment, such as administration of calcium gluconate, insulin with glucose, or dialysis.

🔸Advising dietary changes or obtaining a sodium level is not appropriate until cardiac stability is ensured.

Answer 6

Correct Answers:

Elevated Troponins

Rationale :

🔹Troponins (I and T) are the most sensitive and specific biomarkers for diagnosing acute myocardial infarction (AMI).

🔹 They begin to rise within 3–6 hours after cardiac muscle injury and can remain elevated for 10–14 days, making them ideal for detecting both recent and ongoing damage.

🔹An ECG without ST segment changes does not rule out AMI, particularly in non-ST-elevation myocardial infarction (NSTEMI).

🔹 In such cases, elevated troponins confirm myocardial injury. CK is less specific to the heart, hemoglobin reflects oxygen-carrying capacity, and B-type Natriuretic Peptide (BNP) is used to assess heart failure, not myocardial infarction.

Answer 7

Correct Answers:

Idioventricular Rhythm

Rationale :

✍️Idioventricular rhythm is a ventricular-originated rhythm that typically presents with a wide QRS complex, absence of P waves, and a slow rate (usually 20–40 bpm).

✍️This rhythm is often seen when higher pacemakers fail and the ventricles take over.

✍️ It is a protective mechanism but usually indicates a serious underlying condition, such as post-cardiac arrest or severe heart block.

✍️ It is important to recognize this rhythm as it often requires immediate intervention depending on the patient's symptoms and perfusion status.

Answer 8

Correct Answers:

STEMI

Rationale :

✅ ST-Elevation Myocardial Infarction (STEMI) is characterized by;

• Persistent chest pain

• Elevated ST segment on ECG,

✅They indicate transmural myocardial injury.

✅ This type of myocardial infarction requires emergency intervention such as reperfusion therapy to restore coronary blood flow.

✅Unlike NSTEMI or unstable angina, a STEMI involves a complete blockage of a coronary artery.

✅ Prompt identification and treatment are critical to reduce myocardial damage and improve outcomes.

Answer 9

Correct Answers:

Swelling at the insertion site and cool extremity

Rationale :

🔹Swelling and coolness in the extremity post-cardiac catheterization suggest a vascular complication such as arterial occlusion or hematoma, which may compromise distal blood flow.

🔹This is a medical emergency and must be reported to the cardiologist immediately to prevent limb ischemia or further complications.

🔹Other findings like oozing may require monitoring, but signs of impaired circulation take priority due to their potential to cause permanent damage.

Answer 10

Correct Answers:

Check your skin tor increased bruising

Rationale :

✍️Clients with atrial fibrillation are often prescribed anticoagulants to reduce the risk of thromboembolism.

✍️ A key side effect of these medications is increased bleeding tendency, and patients must be taught to monitor for signs such as bruising, bleeding gums, or hematuria.

✍️ Educating clients to check their skin for bruising increases their awareness of potential adverse effects

✍️ It also helps promote early detection of complications associated with anticoagulation therapy.
