A parent comments that her infant has had several ear infections in the past few months. Why are infants more susceptible to otitis media?

A.

Infants are in a supine or prone position most of the time.

B.

Sucking on a nipple creates middle ear pressure.

C.

The Eustachian tube is short, straight, and wide.

D.

Sucking on a nipple creates middle ear pressure.

Answer and Explanation

The Correct Answer is C

C. The Eustachian tube in infants is shorter, straighter, and wider compared to adults. This anatomy makes it easier for bacteria or viruses from the nasopharynx to travel up the Eustachian tube and infect the middle ear, contributing to the increased susceptibility to otitis media.

A. Infants spend a significant amount of time lying down, whether in a supine (on their backs) or prone (on their stomachs) position. However, this does not increase the risk of otitis media

B. Sucking on a nipple does create pressure changes in the middle ear but it's not the primary reason infants are more susceptible to otitis media.

D. Sucking on a nipple does create pressure changes in the middle ear but it's not the primary reason infants are more susceptible to otitis media

Correct Answer is D

Explanation

D. Pancreatic enzymes should not be mixed with acidic foods or liquids, as this can reduce their effectiveness. Instead, the enzymes should be sprinkled on soft, non-acidic foods or swallowed whole with a glass of water or juice.

A. Pancreatic enzymes are generally safe and well-tolerated when taken as prescribed but they can cause side effects in some individuals. Common side effects may include abdominal pain, diarrhea, constipation, nausea, and bloating.

B. Pancreatic enzymes help individuals with cystic fibrosis digest fat, as well as proteins and carbohydrates. In cystic fibrosis, the pancreas does not produce enough digestive enzymes, leading to malabsorption of nutrients, particularly fat. Supplemental pancreatic enzymes help compensate for this deficiency and improve nutrient absorption.

C. Pancreatic enzymes are typically taken with meals or snacks to aid in digestion. However, if the child is consuming a small meal or snack that contains minimal fat, the enzymes may not be necessary. It's important for the mother to follow the healthcare provider's instructions regarding when and how to administer the enzymes.
