A client with newly diagnosed Crohn’s disease asks the nurse about dietary restrictions. How should the nurse respond?

Choice A reason: Administering an antiemetic addresses vomiting but is not the first priority. Confusion and projectile vomiting in MS suggest increased intracranial pressure or brain injury post-fall, requiring neurological assessment to identify life-threatening conditions like hematoma, which takes precedence over symptom management.

Choice B reason: A head-to-toe neurological assessment is critical first, as confusion and projectile vomiting post-fall in MS indicate potential traumatic brain injury or exacerbation. Assessing pupil response, motor function, and consciousness level identifies neurological deterioration, guiding urgent interventions to prevent further brain damage.

Choice C reason: Determining the last corticosteroid dose is relevant for MS management but not urgent. Confusion and vomiting suggest acute neurological injury, requiring immediate assessment. Steroid history may guide long-term care but is secondary to evaluating current neurological status post-fall.

Choice D reason: Determining the neurological baseline is useful but not the first action. Acute confusion and vomiting require immediate assessment to detect changes like brain injury. Baseline data provide context but delay critical evaluation of current neurological status, making this choice less urgent.

Managing dyspnea in emphysema requires applying knowledge of respiratory mechanics and airway collapse. The nurse must instruct the client on techniques that maintain positive airway pressure during exhalation to prevent premature bronchial collapse, thereby facilitating better alveolar emptying and reducing air trapping for improved gas exchange.

Choice A rationale: While diaphragmatic breathing is beneficial, lying down on the side with knees bent is not the priority for acute dyspnea. This position does not specifically address the air trapping and airway collapse that occur in emphysema during the expiratory phase of respiration.

Choice B rationale: Increasing the breathing rate is counterproductive for a client with emphysema. Tachypnea leads to shallow breathing and increased air trapping, which worsens hypercapnia and respiratory fatigue. Slower, controlled exhalation is required to effectively manage the physiological dead space and improve ventilation.

Choice C rationale: Pursed-lip breathing creates back pressure in the airways, keeping them open longer during exhalation. This allows for more complete emptying of the alveoli, reduces the work of breathing, and helps alleviate the shortness of breath caused by trapped air.

Choice D rationale: Raising hands above the head may temporarily expand the chest wall, but it does not improve the function of the diaphragm. In emphysema, the diaphragm is often flattened; the most effective way to improve gas exchange is through techniques that optimize the expiratory phase.
