While administering ear drops to a toddler, a nurse by pulls the auricle down and back. The mother asks, "Why are you pulling the ear that way?" Which of the following responses should the nurse make?

A. Pulmonary function test:

Pulmonary function tests (PFTs) assess lung function by measuring airflow, lung volume, and gas exchange. While PFTs can provide valuable information about respiratory function, they are not specific to cystic fibrosis and may show abnormalities consistent with various respiratory conditions. However, PFTs are often performed in individuals with cystic fibrosis to monitor lung function over time and assess response to treatment. They are not considered the most definitive test for diagnosing cystic fibrosis.

B. Sweat chloride test:

This option is correct. The sweat chloride test is considered the most definitive diagnostic test for cystic fibrosis. It measures the concentration of chloride in sweat, which is typically elevated in individuals with cystic fibrosis due to defective chloride transport in sweat glands. A sweat chloride concentration above a certain threshold (usually ≥60 mmol/L) is diagnostic of cystic fibrosis, particularly when confirmed with repeat testing.

C. Stool fat content analysis:

Stool fat content analysis evaluates fat absorption and fecal fat excretion, which may be impaired in individuals with cystic fibrosis due to pancreatic insufficiency. However, while stool fat content analysis can provide supportive evidence of malabsorption in cystic fibrosis, it is not considered the most definitive test for diagnosing the condition. Stool fat content analysis is often used in conjunction with other diagnostic tests to assess pancreatic function and nutritional status in individuals with cystic fibrosis.

D. Sputum culture:

Sputum culture involves culturing respiratory secretions to identify bacterial pathogens, which can be useful for diagnosing respiratory infections in individuals with cystic fibrosis. However, sputum culture is not specific to cystic fibrosis and may show similar findings in other respiratory conditions. While respiratory cultures are important for guiding treatment in cystic fibrosis, they are not considered the most definitive test for diagnosing the condition.

A. Onlooker play:

Onlooker play is when a child observes others playing without actively participating themselves. This type of play typically involves watching others engage in activities or play without joining in. It does not directly involve role-playing or hands-on activities to prepare a child for surgery.

B. Therapeutic play:

This is the correct answer. Therapeutic play involves using play activities to help children express their feelings, fears, and concerns about medical procedures or hospitalization. It often includes role-playing and hands-on activities such as practicing medical procedures on dolls or stuffed animals. Therapeutic play helps children become familiar with medical equipment and procedures in a non-threatening environment, reducing anxiety and promoting coping skills.

C. Cooperative play:

Cooperative play involves children playing together, interacting, and collaborating in shared activities. While cooperative play can be beneficial for social development, it does not necessarily involve role-playing or hands-on activities specific to preparing a child for surgery.

D. Play therapy:

Play therapy is a form of psychotherapy that uses play to communicate with and help children express their thoughts and emotions. While play therapy can be therapeutic for children dealing with various issues, including medical procedures, it is typically facilitated by a trained therapist rather than being directly utilized to prepare a child for surgery through role-playing or hands-on activities.
