A nurse is caring for a client who has developed acute respiratory distress syndrome (ARDS). Which of the following findings should the nurse identify as a manifestation of this syndrome?

Rationale:

A. "I understand that I need to inspect my feet daily."Daily foot inspection is essential for individuals with diabetes to identify any cuts, blisters, or signs of infection early. Reduced sensation due to peripheral neuropathy can lead to unnoticed injuries that progress to serious complications if untreated.
B. "I will dry my feet thoroughly when I get out of the shower." Keeping the feet dry, especially between the toes, helps prevent fungal infections and skin breakdown. Moist environments encourage fungal growth, which can worsen foot health in diabetic clients.
C. "It is important to apply lotion to my feet and especially my toes to keep my skin in good health." While moisturizing helps prevent dry, cracked skin, lotion should not be applied between the toes. Moisture trapped between the toes increases the risk of fungal infections and skin maceration in diabetic clients.
D. "I will be very careful when I cut my toenails and will be sure to cut them straight across and then file the edges with an emery board." Cutting toenails straight across and filing the edges helps prevent ingrown toenails and reduces the risk of accidental skin injury. Diabetic clients are advised to be cautious during nail care due to impaired healing and infection risk.
E. "I will wear closed toed shoes." Wearing closed-toed shoes protects the feet from injury and trauma. Open-toed shoes or sandals may expose the feet to injury, and diabetic clients may not feel injuries due to neuropathy.
F. "I am glad I can still go barefoot in the house because I never wear shoes at home."Going barefoot, even indoors, increases the risk of stepping on sharp objects and sustaining unnoticed injuries. Clients with diabetes should always wear well-fitting shoes or protective footwear, even at home.
G. "If I have any foot sores or corns come up, I will see my doctor or go to a podiatrist instead of treating it myself." Diabetic clients should avoid self-treating foot problems like sores or corns. Prompt evaluation by a healthcare provider prevents complications like infections or ulcers, which can escalate quickly in this population.

Rationale:
A. Prominent P waves: Hyperkalemia typically causes a decrease in P wave amplitude and can eventually lead to their disappearance, rather than making them more prominent. Prominent P waves are not characteristic of elevated potassium levels.

B. Narrowed QRS complexes: Hyperkalemia often leads to a widening, not narrowing, of the QRS complex as potassium levels rise. A narrowed QRS complex is not a hallmark finding in clients with elevated potassium.

C. Shortened PR intervals: Hyperkalemia is more commonly associated with prolonged PR intervals. A shortened PR interval is not typically seen in potassium imbalance and would be more relevant in other conduction abnormalities.

D. Peaked T waves: Tall, peaked T waves are the classic early ECG finding in hyperkalemia. They result from increased potassium altering myocardial repolarization and are often the first electrocardiographic sign of elevated serum potassium.
