Calculate the flow rate in mL/hr. and Units/hr. (Equipment used is programmable in whole mL/hr and Show all work) Order: 100 mL 0.45% NS in 45 min by infusion pump. Calculate rate in ml/hr

A.

133 mL/hr

B.

13.3 mL/hr

C.

130 mL/hr

D.

13 ml/hr

Answer and Explanation

The Correct Answer is A

Given:

Volume of fluid: 100 mL

Infusion time: 45 minutes

Step 1: Convert infusion time to hours:

Infusion time (hr) = 45 min / 60 min/hr

Infusion time (hr) = 0.75 hr

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

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

Flow rate (mL/hr) = 100 mL / 0.75 hr

Flow rate (mL/hr) = 133.3333333 mL/hr

Step 3: Round to the nearest whole number:

Flow rate (mL/hr) ≈ 133 mL/hr

Correct Answer is A

Explanation

Given:

Volume of fluid: 3,000 mL

Infusion time: 24 hours

Formula:

Flow rate (mL/hr) = Volume (mL) / Time (hr)

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

Flow rate (mL/hr) = 3,000 mL / 24 hr

Flow rate (mL/hr) = 125 mL/hr

Correct Answer is C

Explanation

A) Yes. Antacids can help alleviate heartburn caused by digoxin.
While antacids can help relieve heartburn, they do not directly alleviate heartburn caused by digoxin. In fact, antacids can interact with digoxin in a way that affects its absorption, potentially leading to suboptimal therapeutic effects.

B) Yes, you can take antacids with digoxin without any interactions.
Antacids can interact with digoxin and reduce its absorption, particularly those that contain aluminum, magnesium, or calcium. Therefore, it is important to space the administration of these medications to avoid potential drug interactions.

C) Yes, but make sure to take the antacid at least 2 hours before or after taking digoxin.. Antacids, especially those containing aluminum, calcium, or magnesium, can decrease the absorption of digoxin, reducing its effectiveness. To prevent this interaction, the nurse should advise the client to take the antacid at least 2 hours before or after taking digoxin to ensure that digoxin is properly absorbed and remains effective.

D) No, antacids can decrease the absorption of digoxin and result in a decreased drug effect.
While this statement is partly true in that antacids can decrease digoxin absorption, it is too absolute to recommend avoiding antacids altogether. The key is proper timing—taking antacids at least 2 hours apart from digoxin.
