A mother brings her 2-month-old to the well-baby clinic. She states that when she kisses her baby, the infant's skin tastes salty.
The nurse should prepare the mother for what standard diagnostic test to screen for cystic fibrosis (CF)?
Sweat-chloride test.
Faecal-fat test.
Pulmonary-function test.
Potassium chloride test.
The Correct Answer is A
The nurse should prepare the mother for a sweat-chloride test to screen for cystic fibrosis (CF). A sweat- chloride test measures the amount of chloride in the sweat and is used to diagnose CF. CF is a genetic disorder that can cause the body to produce thick, sticky mucus that can clog the lungs and pancreas. One of the symptoms of CF is salty-tasting skin due to an increased amount of salt in the sweat. The other options (B, C, and D) are not standard diagnostic tests for screening for CF.

Explanation
Information about the child's reactions to any previous hospitalizations would be particularly helpful in planning care for this six-year-old girl who is being admited for repair of an umbilical hernia. This information can help the nurse anticipate and address any fears or concerns the child may have about the hospitalization and procedure.
A list of achievement timeline for developmental milestones is not particularly relevant in this situation.
A history of rubella, rubeola, or chicken pox is not particularly relevant in this situation.
Information about the mother's use of alcohol, drugs, or cigaretes during pregnancy is not particularly relevant in this situation.
Correct Answer is C
Explanation
The startle reflex, also known as the Moro reflex, is a normal reflex in infants that is present at birth and usually disappears by 3-4 months of age. The reflex is elicited by a sudden loud noise or change in position, and the infant will extend their arms and legs, then bring them back in towards their body.
If a 6-month-old infant is still demonstrating the startle reflex, it may indicate a developmental delay or neurological issue and requires further evaluation by the nurse or healthcare provider.
The other responses are all normal developmental milestones for a 6-month-old infant. By 6 months of age, most infants will have doubled their birth weight, enjoy playing games like peek-a-boo, and have developed the ability to turn their head to locate sounds.
