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?

"Lie down for 1 hour after administering the medication."

"Plan to self-administer this medication for the next 6 months."

"Administer the medication into one nostril once per week."

"Use a nasal decongestant 15 minutes before the medication if you have a stuffy nose."

Answer and Explanation

The Correct Answer is C

Choice A Reason:
There's no requirement to lie down for an hour after administering nasal cyanocobalamin.
Choice B Reason:
The duration of treatment might vary depending on the healthcare provider's instructions and the client's response, so stating a specific duration of 6 months may not be accurate.
Choice C Reason:
"Administer the medication into one nostril once per week. “Nasal cyanocobalamin is typically used weekly for the treatment of pernicious anemia. It's administered into one nostril as directed by a healthcare provider. This method allows for the absorption of vitamin B12 through the nasal mucosa.
Choice D Reason:
Using a nasal decongestant before administering the medication is not typically part of the recommended administration protocol for nasal cyanocobalamin.

Correct Answer is B

Explanation

Choice A Reason:
Extravasation is incorrect. This occurs when the intravenous fluid leaks into the surrounding tissue rather than remaining within the vein. It may cause swelling, pain, and potential tissue damage due to the infused solution's irritant effects.
Choice B Reason:
Phlebitis is correct. Phlebitis refers to the inflammation of a vein often characterized by redness, warmth, swelling, and tenderness along the course of the vein. It can occur due to various reasons, including irritation from the IV catheter, chemical irritation from the infused solution, or infection.
Choice C Reason:
Infiltration is incorrect. Infiltration refers to the inadvertent leakage of the infused fluid into the surrounding tissues. It may cause swelling and discomfort but doesn't typically present with redness and inflammation along the vein.
Choice D Reason:
Venous spasm is incorrect. Venous spasm involves the involuntary contraction of the vein, which can occur in response to irritation or trauma. It may cause temporary difficulty in IV access but does not usually present with redness and inflammation along the vein as the primary signs.

A. BUN 15 mg/dL B. WBC 3,000/mm C. Hct 45% D. Platelets 250,000/mm

Correct Answer is B

Explanation

Choice A Reason:
BUN 15 mg/dL (blood urea nitrogen) is incorrect. An elevated BUN level can indicate kidney dysfunction or dehydration, but it's not typically associated with azathioprine's adverse effects. Azathioprine is known to affect bone marrow, leading to decreased blood cell counts, rather than directly impacting kidney function.
Choice B Reason:
WBC 3,000/mm³ (low white blood cell count) is correct. Azathioprine is an immunosuppressive medication used to treat various conditions, including rheumatoid arthritis. One of its known adverse effects is bone marrow suppression, which can lead to decreased production of blood cells, including white blood cells (WBCs). A low WBC count (leukopenia) can increase the risk of infections due to compromised immune function, making it an important adverse effect to monitor in individuals taking azathioprine.
Choice C Reason:
Hct 45% (hematocrit) is incorrect. A hematocrit of 45% is within the normal range for both men and women. Azathioprine adverse effects usually manifest as blood cell-related issues (such as leukopenia) rather than directly impacting hematocrit levels.
Choice D Reason:
Platelets 250,000/mm³: Platelets within the range of 150,000 to 400,000/mm³ are considered normal. Azathioprine typically affects white blood cells more prominently than platelet counts.
