Pediatric Research Questions Questions
Question 1 of 5
Which of the following would the nurse evaluate as laboratory data that support the occurrence of AIDS?
Correct Answer: D
Rationale: The nurse would evaluate 200 CD 4+ cells as laboratory data that support the occurrence of AIDS. In patients with AIDS, there is a significant decrease in the CD4+ T-lymphocyte count, typically falling below 200 cells/mm³. This low CD4+ cell count increases the risk of opportunistic infections and indicates severe immune suppression, which is characteristic of AIDS. A CD4+ count of 200 or less is an important criterion for the diagnosis of AIDS according to the Centers for Disease Control and Prevention (CDC) and World Health Organization (WHO) guidelines.
Question 2 of 5
A client receiving ferrous sulfate (Fer-Iron) therapy to treat an iron deficiency reports taking an antacid frequently to relieve heart burn. Which nursing instruction should the nurse provide?
Correct Answer: B
Rationale: Antacids can interfere with the absorption of iron from ferrous sulfate. Therefore, it is important to take these medications at least 2 hours apart to ensure proper absorption of the iron supplement. Taking them together can reduce the effectiveness of the ferrous sulfate therapy in treating the iron deficiency. It is not necessary to avoid taking an antacid altogether, but timing is crucial to optimize the benefits of both medications.
Question 3 of 5
A client with human immunodeficiency virus (HIV) undergoes intradermal anergy testing using Candida and mumps antigen. During the 3 days following the tests, there is no induration or evidence of reaction at the intradermal injection sites. The most accurate conclusion the nurse can make is:
Correct Answer: C
Rationale: A client with HIV undergoing intradermal anergy testing with Candida and mumps antigens is suspected to be immunodeficient, making them unable to mount a normal skin response to these antigens. In an immunodeficient individual, the immune system is weakened, leading to a lack of response when exposed to these antigens. A lack of induration or reaction in the 3 days following the test suggests that the client's immune system is not able to mount a normal response, indicating immunodeficiency. The absence of a reaction does not necessarily indicate lack of exposure (Option A), presence of antibodies (Option B), or the absence of allergies (Option D), but rather points to a compromised immune system in an individual with HIV.
Question 4 of 5
A client is diagnosed with megaloblastic anemia caused by vitamin B12 deficiency. The physician begins the client on cyanocobalamin (Betalin-12), 100mcg IM daily. Which substance influences Vitamin B12 absorption?
Correct Answer: A
Rationale: Intrinsic factor is a glycoprotein produced by the parietal cells of the stomach. It is essential for the absorption of vitamin B12 in the intestine. Vitamin B12 binds to intrinsic factor in the stomach, forming a complex that is absorbed in the ileum of the small intestine. Without intrinsic factor, vitamin B12 absorption is significantly impaired, leading to conditions like pernicious anemia, which is a type of megaloblastic anemia caused by vitamin B12 deficiency. By administering cyanocobalamin (Betalin-12) intramuscularly, the need for intrinsic factor in the absorption process is bypassed, which is necessary in cases where intrinsic factor production or function is disrupted.
Question 5 of 5
In addition to weakness and fatigue, which of the following problems should the nurse expect Aisa to exhibit?
Correct Answer: B
Rationale: In addition to weakness and fatigue, the nurse should expect Aisa to exhibit an increased pulse rate. Weakness and fatigue are common symptoms of anemia, a condition characterized by a decrease in the number of red blood cells or hemoglobin in the blood. Anemia can lead to the heart working harder to pump oxygen-rich blood to the body, resulting in an increased pulse rate. Therefore, it is important for the nurse to assess for signs of tachycardia (elevated heart rate) in a patient with anemia.
