A client is prescribed 25 mg/kg of a medication. The weight of the client is 42 kg.
How many milligrams (mg) of medication should be administered to achieve the total prescribed dose?
1250 mg
1150 mg
950 mg
1050 mg
The Correct Answer is B
The nurse should administer 1050 mg of medication to achieve the total prescribed dose.
This answer is correct because it is based on a simple multiplication calculation. The nurse can multiply the prescribed dose per kilogram by the weight of the client in kilograms to get the total dose in milligrams, as follows:
25 mg/kg x 42 kg = 1050 mg
Therefore, the nurse should administer 1050 mg of medication to the client.

Explanation
To find the total amount of heparin, you need to calculate the following:
- The concentration of heparin in units per milliliter
- The volume of heparin infused from 9:00 am to 11:00 am and from 11:00 am to 2:00 pm
- The amount of heparin in units from each time period and the total amount
First, divide the amount of heparin by the volume of D5W to get the concentration in units per milliliter:
25,000 units / 250 mL = 100 units/mL
Next, multiply the infusion rate by the duration to get the volume infused in each time period:
From 9:00 am to 11:00 am (2 hours), the infusion rate is 12 mL/hr:
12 mL/hr x 2 hours = 24 mL
From 11:00 am to 2:00 pm (3 hours), the infusion rate is 10 mL/hr:
10 mL/hr x 3 hours = 30 mL
Then, multiply the volume infused by the concentration to get the amount of heparin in units in each time period:
From 9:00 am to 11:00 am, the volume infused is 24 mL:
24 mL x 100 units/mL = 2400 units
From 11:00 am to 2:00 pm, the volume infused is 30 mL:
30 mL x 100 units/mL = 3000 units
Finally, add the amounts of heparin from each time period to get the total amount:
2400 units + 3000 units = 5400 units
Therefore, the patient received **5400 units** of heparin from 9:00 am to 2:00 pm.
Correct Answer is B
Explanation
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.
