A nurse is preparing to administer nitroglycerine 15 mcg/min by continuous IV infusion. Available is nitroglycerin 25 mg in 250 mL of dextrose 5% in water (D5W). The nurse should set the IV pump to deliver how many mL/hr? (Round to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.

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.

Given:

Volume of fluid: 100 mL

Infusion time: 30 minutes

Drop factor: 60 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) = 100 mL / 30 min

Infusion rate (mL/min) = 3.33 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) = 3.33 mL/min x 60 gtt/mL

Flow rate (gtt/min) = 200 gtt/min
