Which of the following conditions is most commonly associated with Kussmaul respirations?
Diabetic ketoacidosis
Asthma
Pneumonia
Chronic obstructive pulmonary disease (COPD)
The Correct Answer is A
Rationale:
A. Diabetic ketoacidosis (DKA) is most commonly associated with Kussmaul respirations, which are deep, rapid breaths the body uses to eliminate CO₂ and compensate for metabolic acidosis.
B. Asthma causes wheezing, dyspnea, and prolonged expiration due to airway narrowing but not Kussmaul respirations.
C. Pneumonia leads to cough, fever, and shortness of breath, but respirations are not typically Kussmaul in nature.
D. COPD causes chronic hypoventilation, barrel chest, and pursed-lip breathing but not Kussmaul respirations.

Correct Answer is A
Explanation
Rationale:
A. The ABGs show respiratory alkalosis (pH 7.50, PaCO₂ 29) with hypoxemia (PaO₂ 60, SaO₂ 86%). The priority is to administer oxygen via face mask to correct hypoxemia.
B. Mechanical ventilation may be needed if oxygen therapy is ineffective, but it is not the first action.
C. A sedative is not appropriate because the hyperventilation is compensatory for impaired oxygenation.
D. Assessing for pulmonary embolism is important (risk factors: oral contraceptives, smoking, sudden dyspnea), but ensuring oxygenation takes priority in the immediate situation.
Correct Answer is D
Explanation
Rationale:
A. Acute abdominal pain is not a typical manifestation of pulmonary TB; it may occur with extrapulmonary TB affecting the abdomen, but it is not common.
B. Sudden onset of high fever and chills is more characteristic of acute bacterial infections, not the gradual onset of TB.
C. Severe headache and neck stiffness suggest meningitis, which could occur with TB meningitis, but this is less common than pulmonary TB.
D. Persistent cough lasting more than three weeks is a classic symptom of active pulmonary TB, often accompanied by sputum production, hemoptysis, fatigue, and low-grade fever.
