Acidosis in renal failure is more likely to be associated with which of the following:

Correct Answer: D

Rationale: Acidosis in renal failure is associated with a wide anion gap due to the accumulation of unmeasured anions like sulfates and phosphates, which the kidneys fail to excrete effectively.

Correct Answer: B

Rationale: Iron deficiency anemia is the most common cause of microcytic hypochromic anemia, characterized by small, pale red blood cells due to insufficient hemoglobin production.

Correct Answer: A

Rationale: Cystic fibrosis (CF) is a genetic disorder that primarily affects the lungs and digestive system. One of the key characteristics of CF is the production of abnormally thick and sticky mucus in the respiratory system. This thick mucus can obstruct the airways, leading to recurrent lung infections, difficulty breathing, and other respiratory complications. Therefore, Nurse Archie must keep in mind the need to address and manage the thick pulmonary secretions when developing a care plan for Betty, the 9-year-old girl with cystic fibrosis.
