When auscultating the pulmonic valve on which landmark should the nurse place the stethoscope?

Choice A reason: Switching to oral corticosteroids is not indicated for long-term asthma maintenance due to the high risk of systemic adverse effects, including adrenal suppression, osteoporosis, and hyperglycemia. Inhaled corticosteroids remain the gold standard because they deliver localized anti-inflammatory action directly to the bronchial mucosa with minimal systemic absorption and fewer side effects.

Choice B reason: Scheduled follow-up visits establish a therapeutic alliance and allow the nurse to provide positive reinforcement and longitudinal support. Regular monitoring enables the clinician to identify specific barriers to adherence, such as a busy lifestyle, and implement behavioral cues or digital reminders to integrate medication administration into the client's daily routine effectively.

Choice C reason: Instructing a client to use an inhaled corticosteroid only when symptoms occur is a clinical error. Inhaled corticosteroids are maintenance "controller" medications designed for daily use to reduce chronic airway inflammation. They are not "rescue" medications; using them inconsistently fails to prevent the remodeling and hyperresponsiveness characteristic of poorly controlled asthma.

Choice D reason: While providing written instructions on inhaler technique is an essential component of asthma education, it does not directly address the primary problem of forgetfulness or poor adherence. The client's issue is a behavioral one related to scheduling, not a lack of psychomotor skill or misunderstanding of how the device functions during use.

Choice A reason: Scoliosis is clinically defined as a lateral, or sideways, curvature of the spine, often forming an "S" or "C" shape. In adolescents, this is frequently idiopathic and is detected during a physical exam by observing uneven shoulders, asymmetrical hip height, or a visible spinal curve.

Choice B reason: When the anteroposterior diameter equals the transverse diameter, it is described as a barrel chest. This is typically a sign of chronic obstructive pulmonary disease (COPD) or air trapping, not a spinal deformity like scoliosis, and is unusual in an adolescent population.

Choice C reason: A marked depression of the sternum is known as pectus excavatum, or funnel chest. This is a congenital structural deformity of the anterior chest wall and ribs, but it does not involve the lateral curvature of the vertebral column that characterizes a diagnosis of scoliosis.

Choice D reason: Forward protrusion of the sternum and ribs is called pectus carinatum, or pigeon chest. Like pectus excavatum, this is a chest wall deformity. While it may occasionally coexist with other skeletal issues, it is not the defining characteristic of a scoliosis assessment.
