A nurse is preparing to administer lorazepam 2 mg PO.

Available in lorazepam 1 mg tablets.

How many tablets should the nurse administer?

Answer and Explanation

The Correct Answer is B

The nurse should administer 2 tablets of lorazepam 1 mg to give a total dose of 2 mg.
This is calculated by dividing the desired dose (2 mg) by the available dose (1 mg/tablet) to get the number of tablets needed: 2 mg / (1 mg/tablet) = 2 tablets.
Choice A, 1 tablet, is not the correct answer because it would only provide a total dose of 1 mg.
Choice C, 3 tablets, is not the correct answer because it would provide a total dose of 3 mg.
Choice D, 4 tablets, is not the correct answer because it would provide a total dose of 4 mg.

Correct Answer is D

Explanation

NPH insulin is an intermediate-acting insulin that typically starts to work within 1 to 2 hours after injection.
The nurse should observe for hypoglycemia caused by the onset of the medication around 3 hours after administration, which would be around 1000.
Choice A is not correct because it is too soon after administration for the onset of the medication.
Choice B is not correct because it is still too soon after administration for the onset of the medication.
Choice C is not correct because it is still too soon after administration for the onset of the medication.

A. Use a 1-inch needle to inject the medication. B. Use a 22-gauge needle to inject the medication. C. Massage the injection site after administration of the medication. D. Inject the medication into the abdomen above the level of the iliac crest.

Correct Answer is D

Explanation

“Inject the medication into the abdomen above the level of the iliac crest.” When administering heparin subcutaneously, it is appropriate to inject the medication into the abdomen above the level of the iliac crest 1.
Choice A is not correct because a 1-inch needle may be too long for subcutaneous injection.
A shorter needle, such as a 3/8 to 5/8 inch needle, is typically used for subcutaneous injections.
Choice B is not correct because a 22-gauge needle may be too large for subcutaneous injection.
A smaller gauge needle, such as a 25- or 27-gauge needle, is typically used for subcutaneous injections.
Choice C is not correct because massaging the injection site after administering heparin can increase the risk of bruising and should be avoided.
