The physician orders vancomycin hydrochloride 2 g/day by mouth in 4 divided doses.
The pharmacy fills the client's prescription with 500 mg vancomycin hydrochloride capsules.
The nurse should instruct the client to take______capsule(s) per dose.
The Correct Answer is ["1"]
The physician has ordered a total of 2 g/day of vancomycin hydrochloride to be taken in 4 divided doses.
This means that each dose should be 2 g/day ÷ 4 = 0.5 g/dose.
Since the pharmacy has filled the prescription with 500 mg capsules, and 500 mg is equivalent to 0.5 g, the client should take 1 capsule per dose.

Correct Answer is C
Explanation
Unopened vials of insulin should be kept in the refrigerator at a temperature between 36°F to 46°F (2°C to 8°C) 1.
This helps to ensure that the insulin remains safe and effective until its expiration date.
Choice A is incorrect because insulin injected into the abdomen is absorbed more rapidly than insulin injected into other areas such as the thigh.
Choice B is incorrect because insulin should not be shaken vigorously as this can cause it to break down and become less effective.
Instead, gently roll the bottle between your hands to mix it.
Choice D is incorrect because not all types of insulin can be mixed together in the same syringe.
Only certain types of insulin can be mixed together and this should only be done under the guidance of a healthcare provider.
Correct Answer is B
Explanation
The nurse should administer 2.5 tablets.
To determine the number of tablets needed to administer a dose of 5 mg using 2 mg tablets, you can divide the desired dose (5 mg) by the available tablet strength (2 mg/tablet): 5 mg ÷ 2 mg/tablet = 2.5 tablets.
Choice A is incorrect because administering 2 tablets would only provide a dose of 4 mg (2 tablets x 2 mg/tablet = 4 mg).
Choice C is incorrect because administering 2.6 tablets would provide a dose of 5.2 mg (2.6 tablets x 2 mg/tablet = 5.2 mg).
Choice D is incorrect because administering 3 tablets would provide a dose of 6 mg (3 tablets x 2 mg/tablet = 6 mg).
