A nurse is planning care for a group of clients following change-of-shift report. When using clinical decision making, which of the following clients should the nurse assess first?

A) "I'll use pursed-lip breathing when I feel short of breath.": Pursed-lip breathing is a beneficial technique for clients with COPD as it helps keep the airways open longer, reduces the work of breathing, and improves ventilation. This statement indicates the client understands a key management strategy for COPD.

B) "I'll skip my exercises for the week if I feel short of breath.": Regular exercise is important for managing COPD, and while adjustments may be necessary when symptoms are severe, completely skipping exercise can lead to deconditioning and worsening of symptoms. This statement does not reflect appropriate management of COPD.

C) "I will use my inhaler 30 minutes after each meal.": Inhalers should be used as prescribed, usually before activities that might trigger symptoms, such as eating, rather than on a fixed schedule unrelated to symptoms or physician's guidance. This statement indicates a misunderstanding of inhaler use.

D) "I will limit myself to drinking only 1 quart of water each day.": Staying hydrated is important for thinning mucus in COPD. Unless there are specific medical reasons to restrict fluids, such as heart failure, limiting water intake could lead to dehydration and thickened mucus, making breathing more difficult. This statement is not appropriate for managing COPD.

A) Diarrhea: Metabolic alkalosis is more likely to be associated with constipation rather than diarrhea. Diarrhea is typically a cause of metabolic acidosis due to the loss of bicarbonate in stool, rather than a result of metabolic alkalosis.

B) Bradycardia: Bradycardia is not a typical manifestation of metabolic alkalosis. Alkalosis can lead to arrhythmias, but it generally does not cause a slow heart rate. Instead, tachycardia might occur as the body compensates for the altered acid-base balance.

C) Tinnitus: Tinnitus is not a common symptom of metabolic alkalosis. It is more often associated with aspirin toxicity or other conditions affecting the auditory system, rather than changes in acid-base balance.

D) Tetany: Tetany is a common manifestation of metabolic alkalosis. The alkalosis causes a decrease in ionized calcium levels, which increases neuromuscular excitability and can lead to muscle cramps, spasms, and tetany. This is a key sign for nurses to monitor as it indicates significant electrolyte disturbances associated with the alkalotic state.
