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
The nurse should report chest pain to the healthcare provider immediately when caring for a child with sickle cell disease who is experiencing a sickle cell crisis. Chest pain can be a sign of acute chest syndrome, a potentially life-threatening complication of sickle cell disease that requires prompt treatment.
Swelling in the hands or feet, ulcers on the legs, and jaundice are common symptoms of sickle cell disease and do not require immediate reporting to the healthcare provider.
Correct Answer is A
Explanation
Flaring of the nares is a sign of increased respiratory effort, which is a manifestation of acute respiratory distress. This finding occurs when the child is attempting to draw in more air to meet the increased demand for oxygen.
Bilateral bronchial breath sounds can indicate consolidation or a bronchial obstruction, but they are not specific to acute respiratory distress.
Diaphragmatic respirations are a normal finding and may occur in response to respiratory distress, but they do not necessarily indicate acute respiratory distress.
A resting respiratory rate of 35 breaths/min is within the normal range for a 1-year-old child and does not necessarily indicate acute respiratory distress.
