What is the primary result of anemia?
Depressed hematopoietic system.
Presence of abnormal hemoglobin.
Decreased oxygen-carrying capacity of blood.
Increased blood viscosity.
The Correct Answer is C
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 D
Explanation
The correct answer is choice D. Give small amounts of favorite fluids frequently to prevent dehydration.
Choice A rationale:
Having the child wear heavy clothing to prevent chilling is not an appropriate nursing intervention for an infant with an elevated temperature. Infants are more susceptible to temperature regulation issues, and heavy clothing could exacerbate their discomfort and potentially raise their body temperature further.
Choice B rationale:
Giving tepid water baths to reduce fever is not recommended for fever management in infants. Tepid baths might cause discomfort and shivering, which could lead to increased heat production and potential elevation of body temperature.
Choice C rationale:
Encouraging food intake to maintain caloric needs is important, but it might not be well-tolerated by an infant with an elevated temperature and upper respiratory tract infection. Infants often have reduced appetite during illness.
Choice D rationale:
Giving small amounts of favorite fluids frequently to prevent dehydration is an appropriate nursing intervention. Fever and elevated temperature can lead to increased fluid loss through sweating and increased respiratory rate. Offering small, frequent fluid intake helps maintain hydration and prevent dehydration. Using favorite fluids can also encourage the child to drink more.
Correct Answer is A
Explanation
The correct answer is choice A: Administer pancreatic enzymes between meals if at all possible.
Choice A rationale:
Administer pancreatic enzymes between meals if at all possible. This is the correct choice. When educating the parents and child with cystic fibrosis about the administration of pancreatic enzymes, it's important to emphasize that these enzymes should be given between meals whenever feasible. Administering them between meals, when the stomach is less acidic and less likely to release the enzymes prematurely, ensures optimal digestion of food and absorption of nutrients. This approach aligns with the physiological need to supplement pancreatic enzyme function due to the inadequate natural enzyme production in cystic fibrosis.
Choice B rationale:
Pancreatic enzymes can be swallowed whole or sprinkled on a small amount of food taken at the beginning of a meal. This choice is a valid option for administering pancreatic enzymes. While it's true that the enzymes can be taken either by swallowing the capsules whole or by opening them and sprinkling the contents on a small amount of food at the start of a meal, this method can vary based on individual preferences and abilities. However, the primary focus should be on timing (between meals) to achieve the best enzymatic action.
Choice C rationale:
Do not administer pancreatic enzymes if the child is receiving antibiotics. This statement is not accurate. There is no general contraindication to administering pancreatic enzymes while a child is on antibiotics. However, it's important for the healthcare provider to be aware of all the medications the child is taking to ensure there are no potential drug interactions or effects on absorption. Always consult with the healthcare team before adjusting the administration of any medication.
Choice D rationale:
Decrease the dose of pancreatic enzymes if the child is having frequent, bulky stools. This statement is not consistent with typical practice. If a child is experiencing frequent, bulky stools, it may actually indicate that the pancreatic enzyme dosage needs adjustment (increasing the dose rather than decreasing). Bulky stools can suggest poor digestion and absorption, which might require more enzymes to properly break down nutrients. Dosage adjustments should always be made under the guidance of the healthcare provider based on factors such as stool consistency, weight gain, and nutritional status.
