A nurse is teaching a client who has pernicious anemia to self-administer nasal cyanocobalamin. Which of the following information should the nurse include in the teaching?
"Administer the medication into one nostril once per week."
"Lie down for 1 hour after administering the medication."
Plan to self-administer this medication for the next 6 months."
"Use a nasal decongestant 15 minutes before the medication if you have a stuffy nose."
The Correct Answer is A
Choice A rationale: Nasal cyanocobalamin for pernicious anemia is commonly administered once a week. The instruction to administer the medication into one nostril aligns with the correct technique.
Choice B rationale: Post-administration lying down isn't necessary for this medication.
Choice C rationale: The duration of treatment can vary; a fixed duration isn't universally applicable.
Choice D rationale: Using a nasal decongestant isn't a routine part of administering nasal cyanocobalamin for pernicious anemia.

Correct Answer is ["A","C","D"]
Explanation
Choice A rationale: Polypharmacy, the use of multiple medications, increases the risk of adverse drug reactions due to potential drug interactions and increased complexity in medication management for older adults.
Choice B rationale: The absorption rate generally decreases in older adults.
Choice C rationale: Multiple health problems can alter the pharmacokinetics and pharmacodynamics of drugs.
Choice D rationale: Decreased renal function can impair the excretion of drugs and their metabolites, leading to accumulation and toxicity.
Choice E rationale: Body fat percentage might impact drug distribution but is not directly a risk factor for adverse drug reactions.
Correct Answer is B
Explanation
Choice A rationale: Erythromycin lactobionate should be reconstituted with sterile water for injection, not dextrose solution. Dextrose solution can cause precipitation and reduce the effectiveness of the medication.
Choice B rationale: Erythromycin lactobionate is a macrolide antibiotic that can cause ototoxicity, which is damage to the inner ear that can result in hearing loss, tinnitus, or vertigo. The nurse should monitor the client for signs of ototoxicity and report any changes to the provider.
Choice C rationale: Erythromycin lactobionate can cause diarrhea, not constipation. The nurse should advise the client to drink plenty of fluids and monitor for signs of dehydration.
Choice D rationale: Erythromycin lactobionate should be administered over 20 to 60min, depending on the dose and the client's condition. Administering the medication too rapidly can cause phlebitis, thrombophlebitis, or cardiac arrhythmias.
