Centers for Disease Control and Prevention (CDC)

National Institutes of Health (NIH)

Calculate the total volume for all doses:

Answer and Explanation

The Correct Answer is B

A) Drug Enforcement Administration (DEA)
The DEA is primarily responsible for enforcing the controlled substances laws and regulations, including monitoring the manufacturing and distribution of drugs that are classified as controlled substances. While the DEA plays an important role in regulating drugs, particularly those that have a high potential for abuse, it is not the primary authority on drug standards or approval processes.

B) Food and Drug Administration (FDA)
The FDA is the primary authority responsible for drug standards in the United States. The FDA regulates the safety, efficacy, and quality of pharmaceutical drugs, vaccines, biologics, and medical devices. It is responsible for approving new medications, ensuring they meet rigorous standards for safety and effectiveness before they are made available to the public. The FDA also monitors drugs after they are approved, requiring post-market surveillance and, if necessary, issuing recalls or safety warnings.

C) Centers for Disease Control and Prevention (CDC)
The CDC is focused on public health and disease prevention rather than the regulation of drugs. The CDC plays an important role in providing guidelines for the treatment and prevention of diseases, offering recommendations for vaccination schedules, and conducting epidemiological research.

D) National Institutes of Health (NIH)
The NIH is a leading medical research organization that conducts and funds biomedical research. While the NIH plays a crucial role in advancing scientific knowledge and supporting the development of new treatments, it does not have the authority to regulate or set standards for drugs.

Correct Answer is A

Explanation

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

A. Yes. antacids can help alleviate heartburn caused by digoxin. B. Yes, you can take antacids with digoxin without any interactions. C. Yes, but make sure to take the antacid at least 2 hours before or after taking digoxin. D. No, antacids can decrease the absorption of digoxin and result in a decreased drug effect.

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.
