Answer to Question 1

C
Pursed-lip breathing maintains positive pressure in the lungs during the expiratory phase and prevents collapse of the smaller airways. Deep-breathing exercises encourage the patient to take slow deep breaths instead of rapid, shallow breaths. Intermittent positive-pressure breathing machines deliver a volume of air under pressure.

Answer to Question 2

2. Oliguria and altered levels of consciousness

Rationale:
Tumor lysis causes a metabolic emergency. Because of electrolyte imbalance, the signs can be oliguria and altered levels of consciousness. Thrombocytopenia and leukocytosis occur with a hematological emergency. Space-occupying lesions can cause respiratory distress, cyanosis, upper-extremity edema, and neck-vein distension.
