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 D
Explanation
Hypoglycemia, or low blood sugar, can cause an irregular or fast heartbeat 12.
Bradycardia refers to a slower-than-normal heart rate, which is the opposite of what can happen during hypoglycemia.
Choice A is not an answer because dry mucous membranes are not a common symptom of hypoglycemia.
Choice B is not an answer because polyuria, or excessive urination, is not a common symptom of hypoglycemia.
Choice C is not an answer because poria is a type of fungus and is not related to hypoglycemia.
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).
