Correct Answer is B

Explanation

Step 1: Convert weight from lb to kg.

88 lb ÷ 2.2 = 40 kg

Step 2: Calculate total daily dose in mg.

150 mg/kg × 40 kg = 6000 mg

Step 3: Calculate dose per administration (every 6 hr).

6000 mg ÷ 4 = 1500 mg

Step 4: Calculate number of tablets per dose.

1500 mg ÷ 500 mg/tab = 3 tablets

Answer:

3 tablets per dose.

A. "Administer the medication into one nostril once per week.” B. "Lie down for 1 hour after administering the medication.” C. "Use a nasal decongestant 15 minutes before the medication if you have a stuffy nose.” D. "Plan to self-administer this medication for the next 6 months.”

Correct Answer is A

Explanation

Nasal cyanocobalamin is a form of vitamin B12 that is used to treat pernicious anemia.

It is typically administered once per week into one nostril.

Choice B is wrong because there is no need to lie down for 1 hour after administering the medication.

Choice C is wrong because using a nasal decongestant before administering the medication is not necessary and may interfere with the absorption of the medication.

Choice D is wrong because the duration of treatment with nasal cyanocobalamin varies and should be determined by the provider based on the client’s individual needs.
