The nurse identifies the client exhibiting supraventricular tachycardia and calls the provider. Several orders are given. For which of the following orders would the nurse request further clarification? (Select all that apply)

Place defibrillator pads and prepare for defibrillation

Prepare Cardizem subcutaneously

Prepare for synchronized cardioversion

Prepare Adenosine PO

Prepare for Adenosine IV

Answer and Explanation

Correct Answer : A,B,D

Choice A reason: Placing defibrillator pads and preparing for defibrillation is typically not indicated for supraventricular tachycardia (SVT) unless the patient is unresponsive or pulseless, which requires immediate emergency intervention. SVT is usually managed with vagal maneuvers or medications.

Choice B reason: Cardizem (diltiazem) is not administered subcutaneously. It is usually given orally or intravenously for the treatment of arrhythmias. Requesting clarification on this order is necessary to ensure the correct administration route.

Choice C reason: Preparing for synchronized cardioversion is an appropriate order for the treatment of unstable SVT if medications are ineffective. This procedure involves delivering a timed electrical shock to restore normal heart rhythm.

Choice D reason: Adenosine is not administered orally. It is typically given as a rapid intravenous push to treat SVT. Preparing adenosine for oral administration is incorrect and requires clarification to ensure the patient's safety and effective treatment.

Choice E reason: Preparing for adenosine IV is appropriate as it is the correct route of administration for treating SVT.

Correct Answer is ["A","C","D"]

Explanation

Choice A reason: Beta blockers are medications that can slow the heart rate, leading to sinus bradycardia. They are often prescribed for managing hypertension, arrhythmias, and other cardiovascular conditions. They work by blocking the effects of adrenaline on the heart, which reduces heart rate and blood pressure.

Choice B reason: Fever typically causes an increase in heart rate (tachycardia) rather than a decrease. The body's metabolic rate increases to fight infection, resulting in a higher heart rate.

Choice C reason: Athletism can result in sinus bradycardia because athletes often have a lower resting heart rate due to the increased efficiency of their cardiovascular system. Their hearts pump more effectively, requiring fewer beats per minute to circulate blood throughout the body.

Choice D reason: Sleeping naturally leads to a slower heart rate due to the relaxation of the body and reduced metabolic demands during rest. Sinus bradycardia during sleep is generally considered normal and not a cause for concern.

A. Prolonged bleeding B. Dry mucous membrane C. Peaked T-waves D. Polyuria

Correct Answer is C

Explanation

Choice A reason: Prolonged bleeding is not a direct indicator of hyperkalemia. It is more commonly associated with coagulation disorders or conditions affecting blood clotting.

Choice B reason: Dry mucous membranes are more indicative of dehydration rather than hyperkalemia. Dehydration can result from a variety of conditions but is not specific to high potassium levels.

Choice C reason: Peaked T-waves on an electrocardiogram (ECG) are a classic sign of hyperkalemia. Elevated potassium levels affect the cardiac conduction system, leading to characteristic changes in the ECG, such as tall, peaked T-waves, widened QRS complexes, and flattened P-waves.

Choice D reason: Polyuria (excessive urination) is not typically associated with hyperkalemia. It is more commonly seen in conditions like diabetes mellitus or diabetes insipidus.
