A patient is to receive a continuous infusion of Diltiazem at 5 mg/hr for Atrial fibrillation. The medication is supplied 125 mg of Diltiazem in 125 mL of Iv fluid. At what rate should the nurse set the IV pump? (round to the nearest whole number)

Answer and Explanation

The Correct Answer is ["5"]

(desired dose in mg/hr) / (concentration of medication in mg/mL) = infusion rate in mL/hr.

In this case, the desired dose is 5 mg/hr, and the concentration of medication is 125 mg in 125 mL, which simplifies to 1 mg/mL.

Therefore, the infusion rate is 5 mg/hr divided by 1 mg/mL, resulting in an infusion rate of 5 mL/hr.

Rounding to the nearest whole number, the nurse should set the IV pump to 5 mL/hr.

Correct Answer is {"dropdown-group-1":"C","dropdown-group-2":"D","dropdown-group-3":"D"}

Explanation

Atrial fibrillation: This is a common arrhythmia where the atria quiver instead of contracting normally, leading to irregular heart rhythms.

Amiodarone- an antiarrhythmic medication may be used to control the heart rate or rhythm in atrial fibrillation.

Heparin-an anticoagulant prevent thromboembolic events, such as stroke, anticoagulants like heparin, enoxaparin, or newer agents like rivaroxaban are used.

A. Heart rate 100 beats per minute B. + 3 peripheral edema C. Respiratory rate of 24 at rest D. Alert and oriented X 3

Correct Answer is D

Explanation

A. A heart rate of 100 beats per minute is considered tachycardia (a heart rate above 100 bpm). This is not an indicator of improvement in heart failure, as it suggests the heart is working harder than usual. Chronic heart failure can lead to compensatory mechanisms such as tachycardia, but it’s typically not a sign of improvement.
B. Peripheral edema (swelling in the legs, ankles, or feet) is a common symptom of heart failure, resulting from fluid buildup due to poor cardiac output. A rating of +3 edema indicates moderate to severe swelling, which suggests fluid retention and poor circulation. This is a sign of worsening or poorly controlled heart failure, not improvement.
C. A respiratory rate of 24 breaths per minute is slightly elevated, as the normal resting respiratory rate for adults is typically between 12 to 20 breaths per minute. A higher respiratory rate can be a sign of respiratory distress or compensatory breathing due to insufficient oxygenation or fluid buildup in the lungs (pulmonary edema), which are both symptoms of heart failure exacerbation.
D. Being alert and oriented X 3 means the client is aware of time, place, and person, indicating no signs of confusion or cognitive impairment. In the context of chronic heart failure, mental status changes (like confusion or disorientation) can occur due to decreased cerebral perfusion, low oxygen levels, or medications (such as diuretics or digitalis.
