Question 1 of 5
The nurse is discussing vitamin replacement with a client in the clinic. Which vitamin should the nurse discuss with the client in order to increase the absorption of folic acid and iron?
Correct Answer: B
Rationale: Vitamin C enhances the absorption of folic acid and iron. Vitamin Bâ??â?? and folic acid are essential for the maturation of red blood cells. Vitamin B6 serves as a coenzyme in hemoglobin formation. Vitamin E protects blood cells from vitamin E-deficient hemolytic anemia.
Question 2 of 5
A client is being treated for anemia and has a hemoglobin level of 9.6 g/dL. What does the nurse understand is the basic nutritional component of heme in hemoglobin that the client may be deficient in?
Correct Answer: D
Rationale: Iron is the basic nutritional component of heme in hemoglobin. Folic acid is essential for the maturation of red blood cells. Copper (minute amount) is involved in the transfer of iron from storage to plasma.
Question 3 of 5
A client is brought to the emergency department with suspected bleeding esophageal varices. Which hemoglobin level should the nurse immediately report to the physician?
Correct Answer: C
Rationale: The nurse should immediately report a 5.0 g/dL, which is a critical low level. A 13.0 g/dL is a normal level, 11.4 is slightly low, and 10.2 is low.
Question 4 of 5
A client informs the nurse that he is having a difficult time coping with seasonal allergies and has taken some over-the-counter medications to assist with control of symptoms. What results would indicate to the nurse that the client does have allergies?
Correct Answer: A
Rationale: Eosinophils phagocytize foreign material. Their numbers increase in allergies, some dermatologic disorders, and parasitic infections. Basophils are also capable of phagocytosis; they are active in allergic contact dermatitis and some delayed hypersensitivity reactions. Monocytes engulf microbial invaders and display the antigenic surface to T lymphocytes. Neutrophils are a major component of the inflammatory response and defense against bacterial infection.
Question 5 of 5
The nurse is inspecting the tonsils of a client that complains of a sore throat for size and appearance. What is the appropriate documentation for an observation of tonsils that touch the uvula?
Correct Answer: C
Rationale: A scale of 3 is when the tonsils touch the uvula. A 1 is when the tonsils are visible, a 2 is when the tonsils extend medially toward the uvula, and a 4 is when the tonsils touch each other.
