A nurse is instructed to administer 60 mEq of an iron supplement to an anemic client three times a day. The iron supplement botle contains 30 mEq in 10 mL.
How many milliliters of the supplement should the nurse administer in a day?
20 mL
60 mL
30 mL
10 mL
The Correct Answer is B
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.

Correct Answer is A
Explanation
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.
Correct Answer is B
Explanation
The correct angle for giving an intradermal injection is **10 to 15 degrees**. This angle allows the needle to enter the dermis, which is the layer of skin just below the epidermis. The needle should be inserted almost flat against the patient's skin, with the bevel side up. A small blister or bleb should form under the skin after injecting the medication.
