Which outcome is appropriate for the client problem of "ineffective gas exchange" for the client diagnosed with chronic obstructive pulmonary disease (COPD)?

Choice A rationale

Blood glucose levels are important but are not the immediate priority for assessing the cause of severe vomiting and diarrhea with lightheadedness. Electrolyte imbalances are more likely to be the cause.

Choice B rationale

Serum potassium levels should be prioritized as vomiting and diarrhea can lead to significant potassium loss, which can result in dangerous cardiac and neuromuscular symptoms. Assessing potassium levels is crucial in this scenario.

Choice C rationale

Lipid profile is not relevant in the acute assessment of severe vomiting, diarrhea, and lightheadedness. This test is more useful for long-term cardiovascular risk assessment.

Choice D rationale

Thyroid function tests are not immediately relevant to the acute symptoms of vomiting and diarrhea with lightheadedness. Electrolyte imbalances are a more immediate concern.

Choice B rationale

Potassium levels should be reviewed before administering furosemide. Furosemide is a loop diuretic that can cause significant potassium loss through increased urine output. Monitoring potassium is crucial to prevent hypokalemia, which can lead to cardiac arrhythmias and other serious complications.

Choice A rationale

Bicarbonate levels are not directly impacted by furosemide use and are less critical to review in this context. While they are important in assessing acid-base balance, they are not the primary concern when administering furosemide.

Choice C rationale

Phosphate levels are not typically affected by furosemide and are not the main focus before administration. Monitoring phosphate might be important in other scenarios, but it is not directly relevant here.

Choice D rationale

Carbon dioxide levels are more relevant to respiratory function and acid-base balance but are not directly impacted by furosemide. The focus should be on monitoring electrolytes, particularly potassium, to prevent complications from diuretic therapy.
