Question

A nurse is caring for a client in the ICU. The client starts complaining of chest pressure and palpitations. The nurse obtained a 6 seconds’ strip. Identify the rhythm.

Answer 1

Correct Answers:

Supraventricular Tachycardia

Rationale :

⚡The rhythm strip displays a very rapid, regular rhythm with narrow QRS complexes, indicating an origin above the ventricles.

❤️P waves are either absent or hidden within the preceding T waves, which is characteristic of SVT rather than atrial flutter or fibrillation.

📈Unlike atrial flutter, there are no distinct sawtooth flutter waves, and unlike atrial fibrillation, the rhythm is regular, not irregularly irregular.

🚨SVT often causes palpitations, chest pressure, and dizziness due to the rapid heart rate reducing cardiac output.

📌Core Message

Supraventricular tachycardia presents as a regular, narrow-complex rapid rhythm caused by atrial or AV nodal reentry.

Answer 2

Correct Answers:

Decreased preload due to impaired venous return related to increased intrathoracic pressure

Rationale :

💨High levels of PEEP increase intrathoracic pressure, compressing the vena cava and reducing venous return to the right atrium.

❤️This leads to decreased preload, which in turn causes a drop in cardiac output.

⚡The reduced filling pressures may result in ventricular irritability, producing PVCs as an early sign.

🚑The nurse should consider lowering PEEP levels or adjusting volume status to restore optimal hemodynamics.

📌Core Message

High PEEP decreases preload, reducing cardiac output through impaired venous return.

Answer 3

Correct Answers:

Ventricular Fibrillation

Rationale :

⚡Ventricular fibrillation (VFib) presents as a chaotic, irregular waveform with no identifiable P waves, QRS complexes, or T waves.

💁‍♂️It indicates disorganized electrical activity in the ventricles, leading to absence of effective cardiac output and pulse.

🚨VFib is a life-threatening cardiac arrest rhythm that requires immediate defibrillation and CPR.

💉Prompt recognition and use of advanced cardiac life support (ACLS) protocols are crucial to restore perfusion and prevent death.

📌Core Message

Ventricular fibrillation is a pulseless, chaotic rhythm requiring immediate defibrillation and CPR.

Answer 4

Correct Answers:

Start anticoagulation intravenously

Rationale :

🩸In acute pulmonary embolism (PE), the immediate goal is to prevent further clot formation and reduce mortality using IV anticoagulants such as heparin.

⚕️Oral anticoagulants are used later for long-term therapy, not during the acute phase.

💁‍♂️Anticoagulation helps stabilize hemodynamics and allows endogenous fibrinolysis to resolve the embolus.

🚨Prompt treatment is lifesaving since PE compromises oxygenation and right ventricular function.

📌Core Message

Acute PE requires immediate IV anticoagulation to prevent further clot propagation.

Answer 5

Correct Answers:

Hypotension, JVD, muffled heart sounds

Rationale :

❤️This combination—known as Beck’s triad—is the hallmark of acute cardiac tamponade.

💧The accumulation of pericardial fluid compresses the heart, restricting ventricular filling and causing hypotension.

💁‍♂️Venous return backs up into the jugular veins, causing JVD, while muffled heart sounds result from fluid insulation.

⚡Immediate intervention with pericardiocentesis is essential to relieve pressure and restore cardiac output.

📌Core Message

Beck’s triad—hypotension, JVD, muffled sounds—defines cardiac tamponade.

Answer 6

Correct Answers:

Acute arterial occlusion

Rationale :

🦵The 6 Ps represent the classic signs of acute limb ischemia due to sudden arterial obstruction.

⚡The occlusion leads to loss of blood flow, resulting in pain and pallor as the first warning signs.

🩸Pulselessness and paralysis indicate tissue necrosis risk, making it a medical emergency.

🚨Prompt actions like vascular surgery or thrombolytic therapy are needed to restore perfusion.

📌Core Message

6 Ps identify acute arterial occlusion, requiring emergency reperfusion.

Answer 7

Correct Answers:

Provide the client with supplemental oxygen.

Rationale :

💁‍♂️The primary goal in cardiogenic pulmonary edema is to correct hypoxemia caused by alveolar fluid accumulation.

💨Providing supplemental oxygen improves oxygen saturation and tissue perfusion.

🩺Other treatments (e.g., diuretics, morphine, nitroglycerin) address the underlying cause, but oxygen is the immediate priority.

⚡Early oxygen delivery prevents respiratory failure and myocardial hypoxia.

📌Core Message

Oxygen therapy is the first priority in cardiogenic pulmonary edema.

Answer 8

Correct Answers:

Elevated Brain Natriuretic Peptide (BNP)and chest X-ray with cardiomegaly and lungs congestion

Rationale :

🧠BNP elevation reflects ventricular wall stretch due to fluid overload in CHF.

📸A chest X-ray shows cardiomegaly and pulmonary vascular congestion, confirming left-sided failure.

💧These findings differentiate cardiogenic from non-cardiogenic pulmonary edema, such as ARDS.

⚕️Recognizing these markers guides appropriate diuretic and afterload-reducing therapy.

📌Core Message

Elevated BNP and cardiomegaly confirm cardiogenic pulmonary edema.

Answer 9

Correct Answers:

Nonselective beta-blocker initiation in the acute episode

Rationale :

⚠️Starting beta-blockers during acute decompensation may worsen cardiac contractility, reducing cardiac output further.

💊These agents are only resumed once the patient is hemodynamically stable.

💁‍♂️During acute pulmonary edema, the heart requires strong inotropy, not suppression.

🚑The nurse should monitor closely and withhold new beta-blockers until stabilization.

📌Core Message

Nonselective beta-blockers worsen acute heart failure and must be avoided initially.

Answer 10

Correct Answers:

Transthoracic echocardiogram

Rationale :

🩺The echocardiogram is the most specific and practical tool to evaluate heart structure and ejection fraction in CHF.

💁‍♂️It shows ventricular dilation, valvular defects, and wall motion abnormalities in real time.

👉It also quantifies systolic and diastolic function, helping guide treatment.

⚕️Unlike imaging modalities like X-ray, echo provides functional assessment, not just morphology.

📌Core Message

Echocardiogram best evaluates cardiac structure and function in heart failure.
