Calculate the flow rate I mL/hr. and Units/hr. (Equipment used is programmable in whole mL/hr and Show all work) Order: 25,000 units of Heparin in 250 mL to infuse at 11 mL/hr. Calculate rate in units/hr.
900 units/hr
1,000 units/hr
2.000 units/hr
1,100 units/hr
The Correct Answer is D
Given:
Total Heparin in solution: 25,000 units
Volume of solution: 250 mL
Infusion rate: 11 mL/hr
Step 1: Calculate the concentration of Heparin in the solution:
Concentration (units/mL) = Total Heparin (units) / Volume of solution (mL)
Concentration (units/mL) = 25,000 units / 250 mL
Concentration (units/mL) = 100 units/mL
Step 2: Calculate the infusion rate in units/hr:
Infusion rate (units/hr) = Infusion rate (mL/hr) x Concentration (units/mL)
Infusion rate (units/hr) = 11 mL/hr x 100 units/mL
Infusion rate (units/hr) = 1100 units/hr

Correct Answer is ["A","B","D","E"]
Explanation
A) Subcutaneous:
The subcutaneous route involves administering medication into the layer of fat and connective tissue beneath the skin. This method is used for drugs that require slower absorption, such as insulin or certain vaccines.
B) Intramuscular:
The intramuscular route involves injecting medication directly into a muscle. This allows for faster absorption compared to subcutaneous injections, making it ideal for drugs that need to be absorbed quickly, such as vaccines or certain antibiotics.
C) Via a nasogastric tube:
Administering drugs via a nasogastric tube is not considered a parenteral route. The nasogastric (NG) tube delivers medications directly into the stomach via the gastrointestinal tract, which is not part of the parenteral system. Parenteral routes are those that bypass the digestive system, like injections.
D) Intradermal:
The intradermal route involves injecting medication just under the skin, in the dermis. This is typically used for allergy testing or tuberculosis screenings. It is a parenteral route because it bypasses the digestive system.
E) Intravenous:
The intravenous route involves injecting medication directly into a vein, offering rapid absorption and fast onset of action. This method is ideal for critical or emergency situations where immediate medication effects are necessary.
Correct Answer is D
Explanation
Given:
Ordered dose of clindamycin palmitate: 225 mg
Concentration of clindamycin palmitate oral suspension: 75 mg/5 mL
Step 1: Set up the proportion:
Desired dose (mg) / Volume to administer (mL) = Concentration (mg/mL)
Step 2: Substitute the values:
225 mg / Volume = 75 mg/5 mL
Step 3: Solve for the unknown volume:
Volume = 225 mg / (75 mg/5 mL)
Volume = 225 mg x (5 mL / 75 mg)
Volume = 15 mL
