A physician ordered 1/4 strength Isomil 12 oz via nasogastric tube over 6 hours. How much solvent (water) will be needed?
90 ml
270 mL
1440 mL
360 mL
The Correct Answer is B
Given:
Ordered volume of Isomil: 12 oz
Step 1: Determine the volume of Isomil needed for 1/4 strength:
Volume of Isomil for 1/4 strength = Original volume x (1/4)
Volume of Isomil for 1/4 strength = 12 oz x (1/4)
Volume of Isomil for 1/4 strength = 3 oz
Step 2: Calculate the volume of solvent (water) needed:
Solvent volume = Original volume - Volume of Isomil for 1/4 strength
Solvent volume = 12 oz - 3 oz
Solvent volume = 9 oz
Step 3: Convert ounces to milliliters:
1 oz = 29.5735 mL
Solvent volume (mL) = 9 oz x 29.5735 mL/oz
Solvent volume (mL) = 266.1615 mL
Step 4: Round to the nearest whole number:
Solvent volume (mL) ≈ 270 mL

Correct Answer is B
Explanation
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: 1000 mL
Infusion time: 8 hours
Drop factor: 15 gtt/mL
Formula:
Flow rate (gtt/min) = (Volume (mL) / Time (hr)) x Drop factor (gtt/mL) / 60 min/hr
Step 1: Calculate the infusion rate in mL/hr:
Infusion rate (mL/hr) = Volume (mL) / Time (hr)
Infusion rate (mL/hr) = 1000 mL / 8 hr
Infusion rate (mL/hr) = 125 mL/hr
Step 2: Calculate the flow rate in gtt/min:
Flow rate (gtt/min) = (Infusion rate (mL/hr) x Drop factor (gtt/mL)) / 60 min/hr
Flow rate (gtt/min) = (125 mL/hr x 15 gtt/mL) / 60 min/hr
Flow rate (gtt/min) = 1875 gtt/hr / 60 min/hr
Flow rate (gtt/min) = 31.25 gtt/min
Step 3: Round to the nearest whole number:
Flow rate (gtt/min) ≈ 31 gtt/min
