A client is to receive 250,000 units of benzathine penicillin.
G. The medication is available in a vial containing 300,000 units per milliliter. How many milliliters should a nurse administer?
0.4.
0.8.
1.2.
1.6.
The Correct Answer is B
0.8.
To find the answer, you need to use the formula: Dose ordered / Dose available = Volume to administer
In this case, the dose ordered is 250,000 units and the dose available is 300,000 units/mL. So, you need to divide 250,000 by 300,000 and get 0.8333.
Then, you need to round it to one decimal place and get 0.8 mL. Choice A is wrong because it is too low.
If you administer 0.4 mL, you will give only 120,000 units of penicillin G benzathine, which is half of the prescribed dose.
Choice C is wrong because it is too high.
If you administer 1.2 mL, you will give 360,000 units of penicillin G benzathine, which is 44% more than the prescribed dose.
Choice D is wrong because it is also too high.
If you administer 1.6 mL, you will give 480,000 units of penicillin G benzathine, which is almost double the prescribed dose.
The normal range for penicillin G benzathine dosage depends on the type and severity of infection, but it is usually between 50,000 and 2.4 million units per injection.

Correct Answer is D
Explanation
This is because a client who has been diaphoretic for the past six hours is likely to have wet and uncomfortable bed linens that can cause skin breakdown and infection. Changing the bed linens frequently can help keep the client dry and comfortable.
Choice A is wrong because offering the client a bedpan every three hours is not related to diaphoresis and may not meet the client’s elimination needs.
Choice B is wrong because keeping an emesis basin near the bedside is not related to diaphoresis and may not be necessary unless the client has nausea or vomiting.
Choice C is wrong because providing oral care every four hours is not enough to prevent dehydration and dry mouth in a client who has been diaphoretic for the past six hours. The client may need more frequent oral care and fluid intake.
Correct Answer is D
Explanation
Insulin injection sites are rotated to prevent lipodystrophy, which is a condition where the fat tissue under the skin becomes lumpy or dented due to repeated injections.
Lipodystrophy can affect the absorption and effectiveness of insulin.
Choice A is wrong because bruising is not a common complication of insulin
injections. Bruising can occur if the needle hits a blood vessel, but this can be avoided by using a new needle each time and applying gentle pressure after the injection.
Choice B is wrong because infection is not a common complication of insulin
injections. Infection can occur if the skin is not cleaned properly before the injection or if the needle is contaminated, but this can be prevented by washing the hands and using alcohol swabs.
Choice C is wrong because bleeding is not a common complication of insulin
injections. Bleeding can occur if the needle hits a blood vessel, but this can be minimized by using a new needle each time and applying gentle pressure after the injection.
