A school nurse is performing scoliosis screenings. The nurse should recognize which of the following clinical manifestations as an indication of scoliosis?

A) Shaving hairy areas of skin prior to application: While it's important to have a clean area for patch application, shaving can cause irritation and micro-abrasions, potentially leading to increased absorption or skin reactions. Instead, the nurse should clean the area and trim hair if necessary without shaving, to ensure the skin is intact.

B) Wear gloves to apply the patch to the client's skin: Using gloves is essential for infection control and to prevent the nurse from absorbing nicotine through their skin during application. It minimizes the risk of cross-contamination and ensures that the patch is applied safely and effectively.

C) Apply the patch within 1 hr of removing it from the protective pouch: The nicotine patch should be applied immediately after removal from the protective pouch to ensure that it maintains its efficacy. However, there is no strict guideline that requires it to be applied within one hour, making this less critical compared to the importance of proper technique during application.

D) Remove the previous patch and place it in a tissue: Proper disposal of the old patch is important to prevent accidental nicotine exposure. However, the patch should be discarded in a way that minimizes risk, such as folding it upon itself and placing it in a designated waste container rather than just a tissue, which may not secure it adequately.

A) Flattening of the artificial airway cuff: This may indicate issues with the cuff pressure or an air leak but does not directly reflect the effectiveness of suctioning.

B) Decreased peak inspiratory pressure: This is the correct answer. A decrease in peak inspiratory pressure suggests that the airway is clearer, allowing for better airflow and indicating that the suctioning was effective in removing secretions that may have caused airway obstruction.

C) Presence of a productive cough: While this can indicate the expulsion of secretions, it may not be a reliable measure of the effectiveness of suctioning in a mechanically ventilated patient, as they may not be able to cough effectively.

D) Thinning of mucous secretions: While thinning secretions can be beneficial, it does not directly indicate that the suctioning itself was effective. The focus should be on airflow and pressure changes.
