A nurse is assessing a 5-year-old child who has diabetes insipidus and is receiving desmopressin.
Which of the following findings should the nurse identify as an indication that the medication is effective?

The correct answer is: b. “Tighten your muscles before relaxing them when using muscle relaxation techniques.”

Rationale for Choice B: Progressive Muscle Relaxation (PMR) is a well-established technique used in stress management and relaxation therapy. It involves systematically tensing and then relaxing specific muscle groups throughout the body. By tensing the muscles first, individuals can become more aware of the contrast between tension and relaxation, thereby enhancing the relaxation response. This heightened awareness helps individuals recognize and release muscular tension more effectively, leading to deeper relaxation and stress relief.

Rationale for Choice A: Choice A suggests talking to someone admired as the first step in using mindfulness techniques to relax. However, mindfulness practices typically involve cultivating awareness of the present moment without judgment. While seeking support from others may be beneficial for stress management, it is not a foundational aspect of mindfulness practice. Mindfulness often entails individual introspection and observation of one's thoughts, feelings, and bodily sensations.

Rationale for Choice C: Choice C recommends breathing in through the mouth and out through the nose during deep breathing exercises. While there are various breathing techniques utilized in stress management, the typical recommendation for deep breathing exercises is to inhale through the nose and exhale through the mouth. Nasal breathing helps regulate the flow of air, optimizes oxygen exchange, and activates the parasympathetic nervous system, promoting relaxation and stress reduction.

Rationale for Choice D: Choice D proposes imagining a stimulating situation when practicing guided imagery. However, guided imagery is a relaxation technique that involves creating vivid mental images of calming and tranquil scenes, such as a serene beach or peaceful forest. The purpose of guided imagery is to evoke positive emotions, reduce stress, and induce a state of deep relaxation. Imagining stimulating situations may have the opposite effect, potentially increasing arousal and tension rather than promoting relaxation.

In summary, while all choices may have some relevance to stress management, Choice B is the most appropriate as it aligns with the established technique of Progressive Muscle Relaxation. Choices A, C, and D deviate from widely recognized relaxation methods and are therefore considered incorrect in this context.

The correct answer is: b: Perform the procedure prior to meals.

Choice A rationale: The rationale for Choice A involves understanding the technique of percussion in postural drainage for cystic fibrosis management. Percussion is a component of chest physiotherapy that involves rhythmic clapping or tapping on the chest wall to help loosen and mobilize secretions within the airways. However, holding the hand flat during percussion may not effectively transmit the necessary force to the chest wall for optimal secretion mobilization. Instead, cupping the hands allows for better resonance and transmission of percussion force, enhancing the effectiveness of the procedure.

Choice B rationale: Performing postural drainage prior to meals is the recommended timing for several reasons. Firstly, initiating the procedure before meals allows the child's stomach to be relatively empty, reducing the risk of discomfort, nausea, or vomiting during the procedure. Secondly, performing postural drainage before meals helps prevent aspiration of stomach contents, which can occur if the child vomits during or after the procedure. Aspiration poses significant risks, including lung infection and respiratory distress, particularly in individuals with compromised respiratory function such as those with cystic fibrosis.

Choice C rationale: While bronchodilators may play a role in managing airway obstruction in cystic fibrosis, administering them after postural drainage is not a standard practice. Bronchodilators are typically used to alleviate bronchoconstriction and improve airflow in the lungs. However, their administration after postural drainage may not be directly related to the immediate goals of the procedure, which are to mobilize and clear pulmonary secretions. The timing of bronchodilator administration is often guided by the individual's clinical condition and the presence of symptoms such as wheezing or shortness of breath.

Choice D rationale: Performing postural drainage twice daily may not provide adequate frequency for managing secretions in individuals with cystic fibrosis. The goal of postural drainage is to facilitate the removal of thick, tenacious mucus from the airways to improve respiratory function and reduce the risk of complications such as infections. In cystic fibrosis, mucus clearance is essential for maintaining pulmonary health and preventing exacerbations. Therefore, a more frequent regimen, often including multiple sessions of postural drainage per day, may be necessary to achieve optimal therapeutic outcomes and prevent mucus accumulation and airway obstruction.
