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: A soft diet with thin liquids may be recommended for patients with Parkinson's disease who have difficulty swallowing (dysphagia), but it is not the most appropriate intervention for all patients. Dysphagia is common in Parkinson's disease due to impaired muscle movement, and a soft diet can help prevent choking and aspiration.
Choice B reason: Assessing for orthostatic hypotension is crucial in the care of patients with Parkinson's disease. Orthostatic hypotension is a common non-motor symptom where there is a significant drop in blood pressure upon standing. Normal blood pressure should not drop more than 20 mm Hg systolic or 10 mm Hg diastolic within 2 to 5 minutes of standing². This condition can increase the risk of falls, which is a significant concern in this population.
Choice C reason: Exophthalmos, the bulging of the eyes, is not associated with Parkinson's disease. It is typically related to thyroid eye disease, such as Graves' disease, and would not be a relevant assessment for a Parkinson's patient unless there is a known co-existing thyroid condition.
Choice D reason: Limiting fluids to prevent urinary incontinence is not an appropriate intervention for Parkinson's disease. Adequate hydration is essential, and urinary incontinence should be managed with other strategies, such as bladder training, scheduled toileting, and possibly medication, depending on the cause.

Correct Answer is A
Explanation
Choice A reason: Propylthiouracil (PTU) is an antithyroid medication used to treat hyperthyroidism, which can present with symptoms such as weight loss and heat intolerance. The symptoms listed (periorbital edema, cold intolerance, and weight gain) suggest hypothyroidism, for which PTU is not indicated.
Choice B reason: Providing an electric blanket may offer comfort for cold intolerance but does not address the underlying thyroid disorder.
Choice C reason: Restricting fluids is not a standard intervention for thyroid disorders and could potentially lead to dehydration.
Choice D reason: Monitoring for hypotension is important in thyroid disorders, especially if the client is on antithyroid medications, which can affect blood pressure. However, the symptoms presented suggest hypothyroidism, where hypotension is less of a concern compared to hyperthyroidism.
