Review the EKG shown below, which displays rapid, erratic electrical impulses causing ineffective quivering instead of coordinated contraction.
What should be the nurse’s initial intervention?

Place the patient in a left lateral position and monitor vital signs.

Initiate cardiopulmonary resuscitation (CPR) immediately and prepare for defibrillation.

Administer Furosemide intravenously before considering other treatments.

Perform a thorough assessment to determine the cause of the arrhythmia before intervening.

Answer and Explanation

The Correct Answer is B

Choice A rationale

Placing the patient in a left lateral position may not address the root cause of rapid, erratic electrical impulses. It stabilizes the airway but doesn't resolve the arrhythmia.

Choice B rationale

Initiating CPR and preparing for defibrillation are crucial. Rapid, erratic impulses suggest ventricular fibrillation, needing immediate CPR and defibrillation for survival.

Choice C rationale

Administering Furosemide, a diuretic, targets fluid overload but doesn't treat rapid, erratic electrical impulses like ventricular fibrillation, requiring immediate resuscitation.

Choice D rationale

A thorough assessment delays urgent intervention for life-threatening arrhythmias like ventricular fibrillation. Immediate CPR and defibrillation are essential for patient survival.

Correct Answer is ["A"]

Explanation

Choice A rationale

Pregnancy increases venous pressure, leading to stasis and a higher risk of DVT due to hormonal changes and decreased venous return.

Choice B rationale

Oral contraceptive use elevates estrogen levels, increasing blood coagulability and the risk of clot formation, predisposing individuals to DVT.

Choice C rationale

Trauma can damage blood vessel walls, initiating clotting cascades and increasing the likelihood of deep vein thrombosis formation.

Choice D rationale

Immobility causes venous stasis, as muscle contractions that promote blood return are reduced, heightening the risk of DVT due to stagnant blood flow.

A. The QRS duration is 0.30 seconds. B. The T wave is in the inverted position. C. The P-R interval measures 0.32 seconds. D. The P wave falls before the QRS complex.

Correct Answer is D

Explanation

Choice A rationale

A QRS duration of 0.30 seconds is abnormally long. The normal QRS duration is 0.06 to 0.12 seconds, indicating this is not normal sinus rhythm.

Choice B rationale

An inverted T wave is not a characteristic of normal sinus rhythm. It may indicate ischemia or other cardiac abnormalities.

Choice C rationale

A P-R interval of 0.32 seconds is prolonged. The normal P-R interval is 0.12 to 0.20 seconds, thus indicating an abnormal rhythm.

Choice D rationale

The P wave falling before the QRS complex is a key characteristic of normal sinus rhythm, representing the orderly conduction of electrical impulses from atria to ventricles. .
