The nurse is preparing to administer insulin to a diabetic child. Which would be the recommended route for this administration?
Subcutaneous
Intradermal
Intramuscular
Oral
The Correct Answer is A
A. Subcutaneous: Insulin is administered subcutaneously because this route allows for slow, steady absorption into the bloodstream, mimicking the body’s natural insulin release. Common injection sites include the abdomen, thigh, and upper arm, where fatty tissue supports consistent absorption.
B. Intradermal: The intradermal route is used for diagnostic purposes such as allergy or tuberculosis testing. It is not appropriate for insulin administration, as absorption from the dermal layer would be inconsistent and inadequate for glucose control.
C. Intramuscular: Intramuscular insulin administration results in unpredictable and rapid absorption, which can lead to hypoglycemia. This route is generally avoided except in emergency situations when subcutaneous administration is not feasible.
D. Oral: Insulin cannot be administered orally because it is a protein that would be broken down by gastric enzymes before absorption. Therefore, the subcutaneous route remains the standard for effective insulin delivery in diabetic management.

Correct Answer is ["26"]
Explanation
Calculate the total dose of heparin to be administered per hour (units/hr).
Ordered rate: 18 units/kg/hr
Patient weight: 73.4 kg
Total dose rate (units/hr) = 18units/kg/hr × 73.4kg
= 1321.2units/hr.
Calculate the concentration of the available solution in units per milliliter (units/mL).
Available concentration: 25,000 units in 500 mL
Concentration (units/mL) = 25,000units/500mL
= 50units/mL.
Calculate the infusion rate in milliliters per hour (mL/hr).
Infusion rate (mL/hr) = Total dose rate (units/hr) / Concentration (units/mL)
= 1321.2units/hr/50units/mL
= 26.424mL/hr.
Round the answer to the nearest whole number.
= 26 mL/hr.
Correct Answer is B
Explanation
A. Rectus femoris: Although accessible, the rectus femoris is not the preferred injection site in infants because it is close to major nerves and blood vessels, and injections here can cause discomfort and inconsistent absorption of medication.
B. Vastus lateralis: This is the safest and most recommended intramuscular injection site for infants under 12 months. It is a large, well-developed muscle located on the anterolateral thigh and free from major nerves or blood vessels, ensuring effective medication absorption and minimal risk of injury.
C. Dorsogluteal muscle: This site should not be used in infants due to the risk of sciatic nerve injury and underdeveloped gluteal muscles, which make proper absorption unreliable. It becomes safer only in older children and adults.
D. Deltoid: The deltoid muscle is too small in infants to safely accommodate an intramuscular injection and has limited muscle mass, increasing the risk of nerve damage. It is typically reserved for children over 18 months, particularly for small-volume vaccines.
