A client's arterial blood gas (ABG) reads: pH 7.18, PaCO2 54 mm Hg, HCO3 26 mEq/L. What condition does the nurse recognize may contribute to the development of this result? Normal values: pH: 7.35-7.45, PaCO2: 35-45 mm Hg, HCO3: 22-26 mEq/L
Prolonged vomiting
COPD
Chronic renal failure
Anxiety and hyperventilation
The Correct Answer is B
Choice A reason: Prolonged vomiting typically leads to metabolic alkalosis due to the loss of gastric acid, which is not consistent with the ABG results showing acidosis.
Choice B reason: COPD can lead to respiratory acidosis, as indicated by the elevated PaCO2 and low pH in the ABG results, making it a likely contributor to these findings.
Choice C reason: Chronic renal failure can lead to metabolic acidosis, but the HCO3 level is within the normal range, which does not support this as the primary condition.
Choice D reason: Anxiety and hyperventilation usually result in respiratory alkalosis due to the excessive exhalation of CO2, which is the opposite of what the ABG results show.

Correct Answer is B
Explanation
Choice A reason: Tachycardia, or rapid heart rate, is typically a symptom of an overdose of levothyroxine, not an underdose.
Choice B reason: Intolerance to cold is a common symptom of hypothyroidism, which occurs when the thyroid hormone levels are too low, indicating that the levothyroxine dose may be insufficient.
Choice C reason: Weight loss is more commonly associated with hyperthyroidism or an excessive dose of levothyroxine.
Choice D reason: Fine tremors of fingers and hands are also more indicative of hyperthyroidism or too high a dose of levothyroxine.
Correct Answer is B
Explanation
Choice A reason: While it's important to monitor WBC levels for overall health, it is not specifically related to the administration of levodopa/carbidopa for Parkinson's disease.
Choice B reason: Blood pressure should be checked before administering levodopa/carbidopa as these medications can affect blood pressure, potentially causing hypotension.
Choice C reason: Assessing for bleeding is a general nursing action but not specifically related to levodopa/carbidopa administration.
Choice D reason: Providing a high-protein snack can actually interfere with the absorption of levodopa and should be avoided at the time of medication administration.
