What is the desired peripheral capillary oxygen saturation (Spo2) level in the patient with chronic obstructive pulmonary disease?

A. Acetone breath, characterized by a fruity or acetone-like odor on the patient's breath, is a classic sign of DKA. In addition, Kussmaul respirations, which are deep and labored breathing patterns, can occur as the body attempts to compensate for metabolic acidosis in DKA.
C. Nausea and vomiting are common symptoms of DKA and can occur due to metabolic acidosis, electrolyte imbalances, and gastrointestinal disturbances associated with the condition.
F. Tachycardia and hypotension are signs of hemodynamic instability, which can occur in severe cases of DKA due to dehydration, electrolyte imbalances, and the systemic effects of metabolic acidosis.
G. Turning off an insulin pump can lead to insulin deficiency, which is a precipitating factor for DKA, particularly in patients with type 1 diabetes who rely on continuous insulin therapy. This finding is consistent with the development of DKA.
B. Blurred vision and headache can be symptoms of DKA, although they are not specific to this condition. Elevated blood glucose levels and dehydration associated with DKA can lead to osmotic diuresis and subsequent fluid shifts, which may manifest as headache and visual disturbances.

D. A history of type 1 diabetes mellitus (DM) predisposes the patient to DKA but the history of appendix removal at age 7 is not directly relevant to the current presentation of DKA.
E. Alcohol ingestion can contribute to the development of DKA by inhibiting gluconeogenesis and promoting ketoacidosis, particularly if the patient is not consuming adequate carbohydrates and insulin. However, it is not a direct sign of DKA.

D. Patients who have had a stroke are at high risk for aspiration pneumonia due to potential impairment of their swallowing mechanisms and decreased gag reflex, which can occur if the stroke affects the parts of the brain that control these functions. Dysphagia is a common complication of strokes and significantly increases the risk of aspiration.

A. Migraines can cause significant discomfort and sometimes nausea and vomiting, they do not typically impair swallowing or protective airway reflexes. Thus, this patient is not at high risk for aspiration pneumonia.
B. Leukemia itself does not directly increase the risk of aspiration pneumonia. However, if the patient has complications such as severe weakness, altered mental status, or treatment side effects (like mucositis or infections), their risk could be increased, but it is not the primary concern in most leukemia cases.
C. Asthma affects the airways and causes difficulty breathing but does not typically impair swallowing or increase the risk of aspiration. While severe asthma attacks can cause coughing and choking, the primary issue is airway inflammation, not the risk of inhaling food or liquid.
