Which of the following are mild symptoms of respiratory distress? (Select the two responses that apply)

Choice A reason: This is the correct choice. Congestive heart failure can occur in chronic renal failure due to fluid overload and the inability of the kidneys to manage fluid balance.
Choice B reason: Metabolic alkalosis is not typically a major complication of chronic renal failure; metabolic acidosis is more common due to the accumulation of acids in the body.
Choice C reason: Excessive excretion of blood urea nitrogen is not a complication; rather, in renal failure, the kidneys cannot excrete urea nitrogen effectively.
Choice D reason: Hypokalemia (low potassium) can occur, but it is not as major a complication as congestive heart failure in the context of chronic renal failure.

Choice A reason: Trimming toenails straight across is a general foot care recommendation but is not the most critical for preventing complications from an arterial ischemic leg ulcer.
Choice B reason: This is the correct choice. Daily inspection of the feet for skin breakdown is crucial for early detection and prevention of complications associated with arterial ischemic leg ulcers.
Choice C reason: Keeping legs elevated can help reduce swelling but is not as critical as daily foot inspection for preventing ulcer-related complications.
Choice D reason: Wearing shoes and socks is important for protecting the feet but does not directly prevent complications from an arterial ischemic leg ulcer.
