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.

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
“Patient’s platelets 100,000.” A nurse should report a low platelet count to the provider because it may indicate heparin-induced thrombocytopenia (HIT), a serious complication of heparin therapy.
Choice B is not correct because a Prothrombin time (PT) of 12 seconds is within the normal range and does not need to be reported.
Choice C is not correct because Thrombin time (TT) is not typically used to monitor heparin therapy.
Choice D is not correct because a Hematocrit of 35% is within the normal range and does not need to be reported.
