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 maximum number of tablets the patient may have in 24 hours, you need to calculate the following:
- The number of doses the patient may have in 24 hours using the formula: Number of doses = 24 hours / Dosing interval (hours)
- The total dose of ibuprofen in milligrams (mg) for 24 hours using the formula: Total dose (mg) = Number of doses x Prescribed dose (mg)
- The number of tablets of ibuprofen using the formula: Number of tablets = Total dose (mg) / Strength per tablet (mg)
First, use the formula for number of doses to find how many times the patient may take ibuprofen in 24 hours:
Number of doses = 24 hours / Dosing interval (hours)
Since the dosing interval is 6 hours, plug in this value into the formula:
Number of doses = 24 hours / 6 hours
Simplify and solve for the number of doses:
Number of doses = 4
Next, use the formula for total dose to find the amount of ibuprofen in milligrams for 24 hours:
Total dose (mg) = Number of doses x Prescribed dose (mg)
Since the number of doses is 4 and the prescribed dose is 600 mg, plug in these values into the formula:
Total dose (mg) = 4 x 600 mg
Simplify and solve for the total dose:
Total dose (mg) = 2400 mg
Then, use the formula for number of tablets to find how many tablets of ibuprofen are needed:
Number of tablets = Total dose (mg) / Strength per tablet (mg)
Since the total dose is 2400 mg and the strength per tablet is 200 mg, plug in these values into the formula:
Number of tablets = 2400 mg / 200 mg
Simplify and solve for the number of tablets:
Number of tablets = 12
Therefore, the maximum number of tablets the patient may have in 24 hours is **12**.
Correct Answer is C
Explanation
The nurse should administer 12.5 mL of amoxicillin oral suspension.
This answer is correct because it is based on a simple ratio and proportion calculation. The nurse can set up a proportion as follows:
200 mg / 5 mL = 500 mg / x mL
Cross-multiplying and solving for x gives:
x = 12.5 mL
Therefore, the nurse should administer 12.5 mL of amoxicillin oral suspension to deliver 500 mg of the medication to the patient.
