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.

Correct Answer is C
Explanation
Choice A rationale: This prescription indicates a single dose, which seems appropriate for its use.
Choice B rationale: Penicillin G is usually administered in divided doses 4 to 6 hours apart intramuscularly.
Choice C rationale: The nurse should clarify the prescription for warfarin with the provider before administering it. Warfarin is an anticoagulant that is usually given orally, not subcutaneously. The dose of warfarin is also measured in milligrams, not units. The nurse should verify the route, dosage, and frequency of warfarin with the provider to prevent adverse effects such as bleeding or clotting.
Choice D rationale: The frequency and dosage of Tetracycline are standard and within the typical range for treatment.
Correct Answer is B
Explanation
A. Tinnitus, or ringing in the ears, is not a common adverse effect of ergotamine, though it may occur with some other medications used for migraines. Ergotamine primarily affects the blood vessels and nervous system.
B. Paresthesias, which involve tingling, numbness, or a burning sensation, can occur as an adverse effect of ergotamine due to its vasoconstrictive properties. Clients should be informed to report any unusual sensations in their extremities.
C. Blurred vision is not typically associated with ergotamine use. It could be a sign of another underlying condition or side effect from other medications but is not directly related to ergotamine.
D. Hematuria, or blood in the urine, is not a known adverse effect of ergotamine. The medication's effects are mainly related to the vascular system, not the kidneys or urinary tract.
