Which method are for administering drugs by parenteral routes? (Select all that apply.)
Subcutaneous
Intramuscular
Via a nasogastric tube
Intradermal
Intravenous
Correct Answer : A,B,D,E
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 B
Explanation
Given:
Ordered dose of amoxicillin: 30 mg/kg/day divided every 12 hours
Toddler's weight: 33 lbs
Concentration of amoxicillin suspension: 200 mg/5 mL
Step 1: Convert the toddler's weight from pounds to kilograms:
1 pound (lb) = 0.453592 kilograms (kg)
Weight in kg = 33 lbs x 0.453592 kg/lb = 14.968 kg
Step 2: Calculate the total daily dose of amoxicillin:
Total daily dose (mg) = Ordered dose (mg/kg/day) x Weight (kg)
Total daily dose (mg) = 30 mg/kg/day x 14.968 kg
Total daily dose (mg) = 449.04 mg/day
Step 3: Calculate the dose per administration:
Since the medication is given every 12 hours, there are 2 administrations per day.
Dose per administration (mg) = Total daily dose (mg) / Number of administrations per day
Dose per administration (mg) = 449.04 mg/day / 2 administrations/day
Dose per administration (mg) = 224.52 mg
Step 4: Calculate the volume to be administered:
Volume (mL) = Dose per administration (mg) / Concentration (mg/mL)
Volume (mL) = 224.52 mg / (200 mg/5 mL)
Volume (mL) = 224.52 mg x (5 mL / 200 mg)
Volume (mL) = 5.613 mL
Step 5: Round to the nearest tenth:
Volume (mL) ≈ 5.6 mL
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
