What is the usual route for giving an insulin injection?
Intramuscular
Subcutaneous
Intraosseous
Intradermal
The Correct Answer is B
Subcutaneous injection is the usual route for giving insulin because it allows the medication to be absorbed slowly and steadily into the bloodstream. Subcutaneous injection involves inserting a needle into the faty layer of tissue under the skin, usually in the abdomen, upper arm, thigh, or butock.
Intramuscular injection is not the usual route for giving insulin because it may cause rapid and unpredictable absorption of the medication, which can lead to hypoglycemia or hyperglycemia. Intramuscular injection involves inserting a needle into the muscle tissue, usually in the deltoid, vastus lateralis, or ventrogluteal area.
Intraosseous injection is not the usual route for giving insulin because it is reserved for emergency situations when intravenous access is not available. Intraosseous injection involves inserting a needle into the bone marrow, usually in the tibia or humerus.
Intradermal injection is not the usual route for giving insulin because it is mainly used for diagnostic tests, such as tuberculin skin test or allergy test. Intradermal injection involves inserting a needle into the dermis, which is the layer of skin just below the epidermis, usually in the forearm or upper back.

Correct Answer is B
Explanation
To find the milliliters per dose, you need to use the formula for dosage calculation:
Volume (mL) = Dose ordered (mg) / Concentration (mg/mL) x Volume available (mL)
Since the dose ordered is 0.5 grams, the concentration is 125 mg/5 mL, and the volume available is 5 mL, plug in these values into the formula:
Volume (mL) = 0.5 grams / 125 mg/5 mL x 5 mL
However, before you can simplify and solve for the volume, you need to convert the dose from grams to milligrams by multiplying by 1000:
Volume (mL) = 500 mg / 125 mg/5 mL x 5 m
Simplify and solve for the volume:
Volume (mL) = 20 mL
Therefore, the nurse should administer **20 mL** of Amoxil per dose to the patient.
Correct Answer is B
Explanation
The nurse should administer 60 mL of the supplement in a day.
This answer is correct because it is based on a simple unit conversion and multiplication calculation. The nurse can convert 60 mEq to 20 mL by using the ratio given on the botle label, as follows:
30 mEq / 10 mL = 60 mEq / x mL
Cross-multiplying and solving for x gives:
x = 20 mL
Therefore, the nurse should administer 20 mL of the supplement to deliver 60 mEq of the medication to the patient. Since the order is for three times a day, the nurse should multiply 20 mL by 3 to get the total daily dose, which is 60 mL.
