asthma
hyperventilation

Correct Answer : C,E
A. Asthma:
Explanation: Asthma is associated with respiratory alkalosis, not respiratory acidosis. In asthma, there is often hyperventilation leading to a decrease in carbon dioxide levels.
B. Hyperventilation:
Explanation: Correct. Hyperventilation can cause respiratory alkalosis, not respiratory acidosis. It leads to a decrease in carbon dioxide levels.
C. Chronic obstructive pulmonary disease (COPD):
Explanation: Correct. Conditions like COPD can lead to respiratory acidosis. In COPD, there is impaired ventilation, leading to an accumulation of carbon dioxide.
D. Renal insufficiency:
Explanation: Renal insufficiency is not a direct cause of respiratory acidosis. Respiratory acidosis is primarily related to respiratory system dysfunction.

Explanation: Correct. Pneumonia can cause respiratory acidosis. In pneumonia, there may be difficulty in eliminating carbon dioxide due to impaired gas exchange.

Correct Answer is A
Explanation
A. "I have difficulty breathing when walking 30 feet":
Explanation: Difficulty breathing on exertion (dyspnea) is a common symptom of iron-deficiency anemia. This is because iron is a crucial component of hemoglobin, which carries oxygen to body tissues. In the absence of sufficient iron, the oxygen-carrying capacity of the blood is reduced, leading to symptoms such as shortness of breath.
B. "I feel hot all of the time":
Explanation: Feeling hot all the time is not a typical symptom of iron-deficiency anemia. Anemia is more likely to cause symptoms related to poor oxygen delivery, such as fatigue and shortness of breath.
C. "I have a difficult time falling asleep at night":
Explanation: Difficulty falling asleep is not a classic symptom of iron-deficiency anemia. Symptoms are more likely to be related to fatigue and weakness.
D. "I have an increase in my appetite":
Explanation: An increase in appetite is not a typical symptom of iron-deficiency anemia. In fact, individuals with anemia may experience a decrease in appetite.
