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?
Plan to self-administer this medication for the next 6 months.
Administer the medication into one nostril once per week.
Lie down for 1 hour after administering the medication.
Use a nasal decongestant 15 minutes before the medication if you have a stuffy nose.
The Correct Answer is B
This is the recommended dosage for cyanocobalamin nasal spray for pernicious anaemia and vitamin B12 deficiency. Cyanocobalamin nasal gel is used to prevent a lack of vitamin B12 that may be caused by various factors.
Choice A is wrong because the duration of treatment depends on the individual’s response and blood levels of vitamin B. Some people may need to use this medication for longer than 6 months.
Choice C is wrong because there is no need to lie down for 1 hour after administering the medication.
This may cause nasal irritation or drainage.
Choice D is wrong because using a nasal decongestant 15 minutes before the medication may interfere with the absorption of cyanocobalamin. If you have a stuffy nose, you should talk to your doctor about alternative ways to take vitamin B.
