Which statement best describes a conductive hearing loss in a child?
Improves with a cochlear implant.
May accompany otitis media with effusion.
Results from auditory nerve damage.
It is an inherited type of hearing loss.
The Correct Answer is B
A. Cochlear implants are used to treat sensorineural hearing loss, which involves damage to the inner ear or auditory nerve. Conductive hearing loss is usually treated with medical or surgical intervention, such as tubes or hearing aids.
B. Conductive hearing loss occurs when sound waves cannot effectively reach the inner ear, often due to fluid, wax, or structural issues. Otitis media with effusion (fluid in the middle ear without infection) is a common cause of temporary conductive hearing loss in children.
C. Auditory nerve damage causes sensorineural hearing loss, not conductive.
D. While some hearing losses are inherited, conductive hearing loss is typically caused by external or middle ear problems, not genetic factors.

Correct Answer is D
Explanation
A. Pancreatic enzymes are not used to improve metabolism; they are meant to aid digestion, particularly of fats, proteins, and carbohydrates.
B. Enzymes should be taken with meals or snacks, not hours before, to ensure they are present when food enters the small intestine.
C. Taking enzymes after meals reduces their effectiveness because digestion has already started without them.
D. Pancreatic enzymes are given to children with cystic fibrosis to replace the enzymes their pancreas cannot produce. These enzymes help digest fats, improving nutrient absorption and preventing malnutrition and steatorrhea.
Correct Answer is D
Explanation
A. Respiratory acidosis results from hypoventilation, where CO₂ is retained, leading to increased carbonic acid and decreased blood pH. This is the opposite of what is expected with tachypnea.
B. Metabolic alkalosis is typically caused by loss of gastric acid (e.g., vomiting) or excessive bicarbonate intake, not by altered respiratory rates.
C. Metabolic acidosis occurs in conditions such as diarrhea, renal failure, or diabetic ketoacidosis—not directly from changes in respiratory rate.
D. Sustained tachypnea (rapid breathing), especially in a child, leads to excessive exhalation of CO₂, reducing carbonic acid levels and raising blood pH, resulting in respiratory alkalosis.
