Which action by the school nurse is important in the prevention of rheumatic fever?

The correct answer is choice A. The cuff bladder covers 50% to 66% of the length of the upper arm.

Choice A rationale:

Selecting a blood pressure cuff with a bladder that covers 50% to 66% of the length of the upper arm is the appropriate criterion for determining the cuff size for a 2-year-old boy. This range ensures accurate blood pressure measurement by ensuring a proper fit on the arm. If the cuff bladder is too small or too large, it can result in inaccurate readings.

Choice B rationale:

The label "toddler" on the cuff might be helpful in identifying the intended age group, but it doesn't provide precise measurements for cuff sizing. Relying solely on a label might not account for variations in arm sizes within the toddler age group.

Choice C rationale:

The cuff bladder width being 40% of the circumference of the upper arm might not be as accurate as the length-based criterion. A cuff that fits the arm's length is more critical in ensuring proper inflation and accurate blood pressure measurement.

Choice D rationale:

The cuff bladder length covering 80% to 100% of the circumference of the upper arm might result in an excessively large cuff for a 2-year-old, which can lead to inaccurate readings. Length-based sizing is more appropriate for accuracy in this scenario.

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.
