The Correct Answer is B
The nurse should administer 2 tablets.
Since each tablet contains 1.5 mg of dexamethasone, to administer a dose of 3 mg, the nurse should give 3 mg / 1.5 mg/tablet = 2 tablets.
Choice A is incorrect because 1 tablet would only provide a dose of 1.5 mg.
Choice C is incorrect because 3 tablets would provide a dose of 4.5 mg.
Choice D is incorrect because 4 tablets would provide a dose of 6 mg.

Correct Answer is A
Explanation
“Inject air into the regular insulin first.” When mixing regular insulin and NPH insulin in the same syringe, the nurse should instruct the client to inject air into the NPH insulin vial first, then inject air into the regular insulin vial.
After that, the client should draw up the regular insulin into the syringe first, followed by the NPH insulin.
Choice B is not correct because NPH insulin should not be shaken vigorously as it can damage the insulin molecules.
Choice C is not correct because the regular insulin should be drawn up into the syringe first.
Choice D is not correct because regular insulin is a clear solution and should not appear cloudy.
Correct Answer is A
Explanation
The nurse should include in the teaching that the client should use a soft-bristled toothbrush.
Heparin is an anticoagulant that decreases the clotting ability of the blood 1.
Using a soft-bristled toothbrush can help prevent bleeding of the gums while brushing teeth.
Choice B is incorrect because heparin should not be injected deep into the thigh muscle.
Instead, it should be given subcutaneously (under the skin) 2.
Choice C is incorrect because black and tarry stools are not an expected side effect of heparin.
Choice D is incorrect because easy bruising does not indicate that the medication is effective.
Instead, easy bruising may be a side effect of heparin and should be reported to the healthcare provider 1.
