The viral pathogen that frequently causes acute diarrhea in young children is:
Rotavirus.
Salmonella organisms.
Shigella organisms.
Giardia organisms.
The Correct Answer is A
The correct answer is choice A: Rotavirus.
Choice A rationale:
Rotavirus is a viral pathogen that frequently causes acute diarrhea in young children. It is highly contagious and is responsible for a significant portion of severe diarrhea cases worldwide. Rotavirus infections are most common in infants and young children, and they can lead to dehydration, especially in developing countries where access to clean water and proper sanitation might be limited.
Choice B rationale:
Salmonella organisms can cause food poisoning and gastrointestinal infections that lead to diarrhea. However, they are more commonly associated with bacterial infections rather than viral-induced acute diarrhea.
Choice C rationale:
Shigella organisms are also bacterial pathogens that cause diarrhea, specifically bacillary dysentery. While they can cause severe diarrhea, they are not the viral pathogen typically responsible for acute diarrhea in young children.
Choice D rationale:
Giardia organisms are parasites that can cause gastrointestinal infections leading to diarrhea. However, they are not viruses, and they are less commonly associated with acute diarrhea in children compared to rotavirus.

Correct Answer is C
Explanation
The correct answer is choice C. Decreased oxygen-carrying capacity of blood.
Choice A rationale:
Anemia does not primarily result in a depressed hematopoietic system. In fact, anemia often occurs due to various factors that affect red blood cell production or lifespan. The hematopoietic system can be overactive in response to anemia, attempting to compensate for the reduced oxygen-carrying capacity of the blood.
Choice B rationale:
While some anemias may involve the presence of abnormal hemoglobin (e.g., sickle cell anemia), this is not the primary result of anemia. The primary consequence of anemia is a decreased ability of the blood to carry oxygen to the body's tissues.
Choice C rationale:
The correct choice. Anemia leads to a decreased oxygen-carrying capacity of the blood. Hemoglobin, the protein in red blood cells responsible for carrying oxygen, is reduced in quantity or function in various types of anemia. This results in inadequate oxygen delivery to tissues, potentially causing symptoms such as fatigue, weakness, pallor, and shortness of breath.
Choice D rationale:
Increased blood viscosity is not a primary result of anemia. Anemia tends to reduce blood viscosity because there are fewer red blood cells and less hemoglobin present, which makes the blood more fluid and less viscous. Increased blood viscosity is more commonly associated with conditions like polycythemia, where there is an excess of red blood cells.
Correct Answer is C
Explanation
The correct answer is Choice C: Epispadias.
Choice A rationale:
Chordee is not the correct term to identify when the meatal opening is located on the dorsal surface of the penis. Chordee refers to the downward curvature or bending of the penis, often associated with hypospadias or other congenital conditions.
Choice B rationale:
Hypospadias is not the correct term for this condition. Hypospadias refers to a congenital condition where the opening of the urethra is located on the underside of the penis rather than at the tip. It is not related to the meatal opening being on the dorsal surface.
Choice C rationale:
Epispadias. This is the correct choice. Epispadias is a congenital malformation where the meatal opening is located on the dorsal (upper) surface of the penis. It is a rare condition and requires surgical intervention for correction.
Choice D rationale:
Phimosis is not the correct term for this condition. Phimosis refers to the tightness of the foreskin that prevents it from being pulled back over the tip of the penis. It does not relate to the positioning of the meatal opening.
