A mother calls a nurse to say that she lost the measuring cup that comes with the cough syrup botle. How many teaspoons should the nurse recommend for the child if the dose is 10 mL?

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.

Insulin is a hormone that helps regulate blood sugar levels. It is usually injected into the fat layer just under the skin (subcutaneous or SubQ) using a syringe and needle or a pen-like device². Insulin syringes are marked in units of insulin, not milliliters or cubic centimeters. The most common insulin syringe holds 1 mL of fluid and has markings for 100 units of insulin². A U-100 syringe means that for every 1 mL of fluid, there are 100 units of insulin³.
To administer 14 units of insulin, you would need to draw up 0.14 mL of fluid in a U-100 syringe. You would inject the insulin into your abdomen, upper arm, butocks, hip, or the front or side of the thigh¹. You would use a different area within the site each time you inject insulin to prevent lumps, swelling, or thickened skin¹.

The other options are incorrect because:

b) There is no need to divide the dose into two injections. This would increase the risk of infection and pain.

c) A tuberculin syringe is not designed for insulin administration. It is marked in milliliters or cubic centimeters, not units of insulin. Using a tuberculin syringe could result in an incorrect dose of insulin.

d) The timing of insulin administration depends on the type and duration of insulin. Some insulins are taken before meals, some are taken after meals, and some are taken once or twice a day. The primary healthcare provider should specify when to take the insulin.
