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 A
Explanation
To calculate the dose in milligrams per hour, we need to convert the patient's weight from pounds to kilograms.
Patient's weight: 110 lb
To convert pounds to kilograms, we use the conversion factor: 1 lb = 0.4536 kg
Patient's weight in kilograms: 110 lb * 0.4536 kg/lb = 49.895 kg (rounded to 3 decimal places
The physician has ordered Dobutamine at a dose of 10 mcg/kg/min.
Dose required = 10 mcg/kg/min * 49.895 kg = 498.95 mcg/min
Next, we need to convert the dose from micrograms to milligrams.
498.95 mcg/min = 0.49895 mg/min
Finally, to determine the dose in milligrams per hour, we multiply the dose in milligrams per minute by 60 minutes to convert it to an hourly rate.
0.49895 mg/min * 60 min/hr = 29.937 mg/hr (rounded to 3 decimal places)
Therefore, the correct answer is:
a. 30 mg/hr
Correct Answer is D
Explanation
This is a dosage calculation problem. To solve it, we need to use the formula:A
Desired dose ÷ Available dose × Available quantity = Quantity to give
In this case, the desired dose is 30 mg, the available dose is 20 mg/mL, and the available quantity is 1 mL. Plugging these values into the formula, we get:
30 ÷ 20 × 1 = 1.5
Therefore, the nurse should administer **1.5 mL** of liquid oxycodone hydrochloride to the patient.
