Order: Ampicillin 2 is added to 50 mL D5W to infuse over 40 minutes. Drop factor: 15gtt/mL. For IV reconstitute with 10 mL of diluent to 1g per 10 mL. (Consider the medication added in the volume of fluid) Calculate the rate in gtt/min at which the IV should infuse?

A.

23 gtt/min

B.

26 gtt/min

C.

25 gtt/min

D.

22 gtt/min

Answer and Explanation

The Correct Answer is A

Given:

Volume of fluid: 50 mL (DSW) + 10 mL (for reconstitution) = 60 mL

Infusion time: 40 minutes

Drop factor: 15 gtt/mL

 

Formula:

Flow rate (gtt/min) = (Volume (mL) / Time (min)) x Drop factor (gtt/mL)

 

Step 1: Calculate the infusion rate in mL/min:

Infusion rate (mL/min) = Volume (mL) / Time (min)

Infusion rate (mL/min) = 60 mL / 40 min

Infusion rate (mL/min) = 1.5 mL/min

 

Step 2: Calculate the flow rate in gtt/min:

Flow rate (gtt/min) = Infusion rate (mL/min) x Drop factor (gtt/mL)

Flow rate (gtt/min) = 1.5 mL/min x 15 gtt/mL

Flow rate (gtt/min) = 22.5 gtt/min

 

Step 3: Round to the nearest whole number:

Flow rate (gtt/min) ≈ 23 gtt/min

Related Questions

Correct Answer is C

Explanation

A) Simvastatin:
Simvastatin is a medication used to lower cholesterol levels by inhibiting HMG-CoA reductase, an enzyme involved in the production of cholesterol in the liver. It is not an angiotensin-converting enzyme (ACE) inhibitor. Therefore, it does not have a direct effect on blood pressure or the renin-angiotensin system.

B) Losartan:
Losartan is an angiotensin II receptor blocker (ARB), not an ACE inhibitor. Like ACE inhibitors, ARBs are used to treat conditions like hypertension and heart failure, but they work differently by blocking the receptors that angiotensin II binds to, rather than inhibiting the enzyme that converts angiotensin I to angiotensin II.

C) Quinapril:
Quinapril is an ACE inhibitor. ACE inhibitors block the enzyme angiotensin-converting enzyme, which converts angiotensin I into angiotensin II, a potent vasoconstrictor. By inhibiting this conversion, ACE inhibitors like quinapril help lower blood pressure, reduce strain on the heart, and treat conditions like hypertension and heart failure.

D) Metoprolol:
Metoprolol is a beta-blocker, not an ACE inhibitor. It works by blocking beta-adrenergic receptors in the heart, which helps to lower heart rate and blood pressure. It is often used in the management of hypertension, heart failure, and to prevent heart attacks, but it does not affect the renin-angiotensin system like ACE inhibitors.

Correct Answer is B

Explanation

Given:

Volume of fluid: 180 mL

Infusion time: 40 minutes

Step 1: Convert infusion time to hours:

Infusion time (hr) = 40 min / 60 min/hr

Infusion time (hr) = 0.67 hr

Step 2: Calculate the infusion rate in mL/hr:

Infusion rate (mL/hr) = Volume (mL) / Infusion time (hr)

Infusion rate (mL/hr) = 180 mL / 0.6667 hr

Infusion rate (mL/hr) = 269.987 mL/hr

Step 3: Round to the nearest whole number:

Infusion rate (mL/hr) ≈ 270 mL/hr
