The following is found during the assessment of a 1-month-old infant. Which of the following would lead the nurse to suspect a cardiac defect?
weight gain
hyperactivity
pink mucous membranes
poor nutritional intake
The Correct Answer is D
A. Weight gain is typically a sign of adequate nutrition and growth, not a concern for a cardiac defect.
B. Hyperactivity is not characteristic of infants, especially at 1 month of age, and is not a common sign of a cardiac issue in this age group.
C. Pink mucous membranes indicate adequate oxygenation, which does not suggest a cardiac defect.
D. Poor nutritional intake in an infant may signal an underlying cardiac defect, particularly if accompanied by fatigue with feeding, diaphoresis, or failure to thrive. Infants with congenital heart defects often have difficulty feeding due to increased energy expenditure and reduced oxygenation, making this a key red flag.

Correct Answer is A
Explanation
A. The sweat chloride test is the gold standard for diagnosing cystic fibrosis (CF). A chloride concentration greater than 60 mEq/L is diagnostic for CF in children.
B. Pulmonary function tests can assess lung capacity and function, but they are not diagnostic and may be difficult to perform reliably in very young children.
C. Stool fat analysis can indicate malabsorption, which is common in CF, but it is not specific or confirmatory for the disease.
D. A sputum culture may detect bacterial colonization (e.g., Pseudomonas), which is common in CF, but it does not confirm the diagnosis.
Correct Answer is B
Explanation
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.
