The nurse responds that this procedure may stimulate which?

• Vagus nerve to slow the heart rate
• Vagus nerve to increase the heart rate
• Diaphragmatic nerve to slow the heart rate
• Diaphragmatic nerve to increase the heart rate
• Vagus nerve to slow the heart rate

Carotid sinus massage is one maneuver used for vagal stimulation to decrease a rapid heart rate and possibly terminate a tachydysrhythmia. The other maneuvers are the Valsalva maneuver of inducing the gag reflex and asking the client to strain or bear down. Medication therapy is often needed as an adjunct to keep the rate down or maintain the normal rhythm.The nurse is assisting in caring for a client in the telemetry unit who is receiving an intravenous infusion of 1000 mL 5% dextrose with 40 mEq of potassium chloride. Which occurrence observed on the cardiac monitor indicates the presence of hyperkalemia?

• Tall, peaked T waves
• ST segment depressions
• Shortened P-R intervals
• Shortening of the QRS complex
• Tall, peaked T waves

The symptoms of hyperkalemia relate to its effect on the myocardial muscle. These include changes noted on the ECG, such as tall, peaked T waves, prolonged P-R interval, widening of the QRS complex, shortening of the Q-T interval, and disappearance of the P wave. Other cardiac symptoms include ventricular dysrhythmias that may lead to cardiac arrest. ST-segment depression is noted in hypokalemia.

The nurse is assisting in caring for a client in the telemetry unit and is monitoring the client for cardiac changes indicative of hypokalemia. Which occurrence noted on the cardiac monitor indicates the presence of hypokalemia?

• Tall, peaked T waves
• ST-segment depression
• Prolonged P-R interval
• Widening of the QRS complex
• ST-segment depression

In the client with hypokalemia, the nurse would note ST-segment depression on a cardiac monitor. The client may also exhibit a flat T wave.Options 1, 3, and 4 are cardiac findings noted in the client with hyperkalemia.A client's blood pressure is 100/78 mm Hg; the client has tachycardia and is cool and pale. The nurse assists the client to which position to promote tissue oxygenation and alleviate hypoxia?

• Supine
• Left lateral
• Semi-Fowler's
• Trendelenburg's
• Semi-Fowler's

Coolness, pallor, and tachycardia are consistent with clinical indicators of hypoxia related to inadequate cardiac output. To reduce the myocardial workload, improve cardiac output, and promote tissue oxygenation, the nurse positions the client in the semi-Fowler's position to maintain perfusion to vital organs and promote chest expansion (option 3) so long as the client's neurological status is stable. The supine position removes the strain on the heart of pumping blood against gravity into the cerebral vasculature effectively; however, a flat position can lead to excessive preload and increase the cardiac workload (option 1). Left-lateral position could be satisfactory (option 2), but until the client is stable and unless the client is at risk for aspiration, semi-Fowler's position is a better choice. Trendelenburg's position is used when the client experiences profound hypotension or shock (option 4).The nurse is caring for a client with a new onset of atrial fibrillation. Which prescribed treatments should the nurse expect? Select all that apply.

• Defibrillation
• Digoxin (Lanoxin)
• Warfarin (Coumadin)
• Electrical cardioversion
• Amiodarone (Cordarone)
• Digoxin (Lanoxin)
• Warfarin (Coumadin)
• Electrical cardioversion

The three goals of treatment for atrial fibrillation are ventricular rate control, prevention of embolic stroke, and restoration and maintenance of normal sinus rhythm. Digoxin (Lanoxin) is used for ventricular rate control. Warfarin (Coumadin) is used to decrease the risk of embolic stroke.Electrical cardioversion is used to restore normal sinus rhythm. Amiodarone (Cordarone) is used to treat ventricular tachycardia or ventricular fibrillation. Defibrillation is the treatment of choice for ventricular fibrillation. Terms (5) Hide definitions
