A nurse is assisting with teaching a group of newly licensed nurses about medication administration.
The nurse should include that which of the following medications is administered using the Z-track method?
Vitamin B12.
Folic acid.
Epoetin alfa.
Iron dextran.
The Correct Answer is D
Choice A rationale
Vitamin B12 is administered intramuscularly but does not require the Z-track method as it does not irritate subcutaneous tissues. The Z-track method is reserved for drugs causing tissue staining or irritation.
Choice B rationale
Folic acid is typically given orally or intravenously and does not necessitate the Z-track method. It is well-tolerated by subcutaneous tissues and does not cause irritation.
Choice C rationale
Epoetin alfa is administered subcutaneously or intravenously without requiring the Z-track method. It is used to stimulate red blood cell production and does not stain or irritate tissues.
Choice D rationale
Iron dextran requires the Z-track method due to its potential to stain and irritate subcutaneous tissues. This method prevents leakage into surrounding tissue, ensuring proper drug absorption. .

Correct Answer is A
Explanation
Choice A rationale
Cracks at the corners of the mouth, or cheilosis, are often associated with nutritional deficiencies like iron or vitamin B deficiencies. Monitoring for these cracks helps diagnose and treat the underlying condition.
Choice B rationale
A reddened tongue is typically associated with vitamin B12 deficiency or other conditions but not cheilosis. It can help identify a different deficiency or condition.
Choice C rationale
Pale conjunctiva is an indicator of anemia but does not specifically correlate with cheilosis. It suggests reduced hemoglobin levels due to iron deficiency.
Choice D rationale
Brittle fingernails may result from chronic iron deficiency anemia but are not directly related to cheilosis. They serve as additional evidence of prolonged anemia.
Correct Answer is A
Explanation
Choice A rationale
Venous stasis ulcers typically present as open sores with irregular borders. This is due to chronic venous insufficiency leading to sustained pressure in lower extremities, impairing blood flow and causing tissue breakdown. The irregular shape results from uneven tissue damage.
Choice B rationale
Dry, scaly patches of skin are indicative of other conditions, such as eczema or psoriasis, rather than venous stasis ulcers. These patches are not directly caused by impaired venous circulation or pressure-induced tissue damage.
Choice C rationale
Redness and warmth around the ulcer site can indicate infection, not the primary characteristic of venous stasis ulcers. Stasis ulcers are more commonly associated with chronic wounds and slow healing due to venous congestion.
Choice D rationale
Shiny skin with loss of hair growth is more commonly observed in arterial insufficiency rather than venous stasis ulcers. Arterial insufficiency leads to inadequate oxygen delivery to tissues, causing trophic changes like shiny skin and hair loss.
