You are instructed to administer 40 mg of methadone (Dolophine) subcutaneously for opioid detoxification. Given that you have a concentration of 30 mg/mL on hand, how much should you draw into the syringe?

Choice A rationale:
While it's true that dehydration can lead to incontinence, simply stating this fact to the patient doesn't directly address the issue of dehydration. It doesn't provide actionable steps to correct the dehydration.
Incontinence can be a result of dehydration, but addressing the dehydration is the primary concern to prevent further complications.
Providing information about incontinence might be helpful in other contexts, but it's not the most effective advice to address mild dehydration in this specific scenario.
Choice B rationale:
Diuretics promote fluid loss through urination, which can worsen dehydration.
Advising the patient to take a diuretic in the morning would be counterproductive in this case. The goal is to increase fluid intake, not further deplete fluid levels.
It's important to consider the patient's medications and potential interactions before suggesting any changes to their medication regimen.

Choice C rationale:
Regular fluid intake is essential for maintaining hydration and replenishing lost fluids.
This advice directly addresses the issue of dehydration by encouraging the patient to consume fluids consistently. Drinking fluids every 1 to 2 hours can help restore fluid balance and prevent further complications.
It's a simple, actionable, and effective measure to address mild dehydration.
Choice D rationale:
While reducing sodium intake can be beneficial for some individuals with hypertension or other conditions, it's not the most relevant advice for addressing mild dehydration.
Sodium restriction might be appropriate in certain cases, but it doesn't directly address the immediate need to increase fluid intake.
The primary focus in this situation should be on replenishing fluids, not restricting sodium.

Choice A rationale:
Uncompensated Respiratory Acidosis is characterized by a low pH (less than 7.35) and a high pCO2 (greater than 45 mmHg). In this case, the pH is slightly elevated (7.46), making this option less likely.
While the pCO2 is elevated (46 mmHg), the body has begun to compensate, as evidenced by the elevated HCO3 (29 mEq/L). This partial compensation does not align with an uncompensated respiratory acidosis.
Choice B rationale:
Compensated Metabolic Acidosis would present with a normal pH (7.35-7.45) due to full compensation by the respiratory system. In this case, the pH is slightly elevated (7.46), which is not consistent with full compensation.
Additionally, the HCO3 is elevated (29 mEq/L), which is characteristic of metabolic alkalosis, not acidosis.
Choice C rationale:
Partially Compensated Metabolic Alkalosis is the most likely interpretation based on the ABG results. The pH is elevated (7.46), indicating alkalosis.
The HCO3 is also elevated (29 mEq/L), which is the primary cause of metabolic alkalosis.
The pCO2 is elevated (46 mmHg), which is a compensatory mechanism to try to normalize the pH. However, the compensation is not complete, as the pH is still slightly elevated.
This partial compensation is consistent with partially compensated metabolic alkalosis.
Choice D rationale:
Partially Compensated Respiratory Acidosis would present with a low pH (less than 7.35) and an elevated pCO2 (greater than 45 mmHg).
The HCO3 would also be elevated, but to a lesser degree than in metabolic alkalosis, as it's a secondary compensatory mechanism.
In this case, the pH is slightly elevated (7.46), making respiratory acidosis less likely.
