A nurse is preparing to apply a pulse oximeter to a child who is having an acute asthma attack. Select the areas the nurse can correctly place the pulse oximeter.
(Select All that Apply.)

A. Upright: In an upright position, gravity helps expand the lungs, allowing for maximal ventilation and improved oxygenation. This position helps the diaphragm move downward and increases lung volume, making it easier to breathe.

B. Side-lying: Side-lying positions may be helpful in certain situations, such as in cases of aspiration pneumonia, but they do not provide the best lung expansion for respiratory failure.

C. Supine: Lying flat on the back can increase the work of breathing and make it harder for the lungs to fully expand, especially in a child with respiratory distress.

D. Prone: The prone position is sometimes used in cases of acute respiratory distress syndrome (ARDS) in adults, but it is not commonly recommended for children with pneumonia unless specifically ordered by the healthcare provider.

A. "Bradycardia is an early indicator of a pneumothorax.": Bradycardia is not an early indicator of a pneumothorax. Common signs of pneumothorax in cystic fibrosis include sudden chest pain, difficulty breathing, and decreased breath sounds, not bradycardia.

B. "Administer a bronchodilator to the child after chest percussion therapy.": Chest percussion helps loosen secretions, and bronchodilators should be administered after the therapy to help open the airways and allow the mucus to be cleared more effectively.

C. "Engage the child in daily aerobic exercise.": While exercise is beneficial for children with cystic fibrosis, it should be tailored to the child's physical condition. Aerobic exercise might not be suitable for all children with CF, especially during exacerbations or respiratory distress.

D. "A pigeon-shaped chest might become evident as the disease progresses.": While a pigeon-shaped chest (pectus carinatum) can occur with CF due to chronic lung infections and hyperinflation, it is not the most immediate concern compared to respiratory therapy or infection control.
