Question 3 of 5
The following morphological features are characteristic of iron deficiency anemia:
Correct Answer: C
Rationale: The correct answer is C: Hypochromic, microcytic. In iron deficiency anemia, there is a decrease in hemoglobin content (hypochromic) and a decrease in red blood cell size (microcytic) due to insufficient iron for hemoglobin synthesis. Normochromic (choice A) and normocytic (choice B) would not be characteristic of iron deficiency anemia. Hypochromic, macrocytic (choice D) is more indicative of a different type of anemia, such as megaloblastic anemia caused by vitamin B12 or folate deficiency.

Correct Answer: C
Rationale: The correct answer is C because the complement system enhances phagocytosis by opsonization, making it easier for phagocytes to engulf and destroy pathogens. Option A is incorrect as the complement system is not part of adaptive immunity. Option B is incorrect as antibodies are part of the humoral immune response, not the complement system. Option D is incorrect as the complement system consists of proteins, not enzymes.
Question 5 of 5
The community health nurse is conducting a research study and is identifying clients in the community at risk for latex allergy. Which client population is most at risk for developing this type of allergy?
Correct Answer: C
Rationale: The correct answer is C: Children in day care centers. Children in day care centers are at higher risk for latex allergy due to frequent exposure to latex-containing products like gloves, pacifiers, and toys. The immature immune system of children increases their susceptibility to developing allergies. Hairdressers (choice A) are also at risk due to prolonged exposure to latex gloves. The homeless (choice B) and individuals living in a group home (choice D) are not specifically at higher risk compared to children in day care centers.
