A nurse is providing teaching to a client newly diagnosed with Parkinson's disease who is prescribed carbidopa/levodopa. What should be included in client teaching?

This is a safe medication that is associated with minimal side effects

Stop the medication if there is increased urination

Change position slowly to prevent orthostatic hypotension

Double the dose if a dose is missed at the next scheduled time

Answer and Explanation

The Correct Answer is C

A. This is a safe medication that is associated with minimal side effects: Carbidopa/levodopa is an effective medication for managing the symptoms of Parkinson's disease, but it is not without side effects. Common side effects include nausea, dizziness, dyskinesia (involuntary movements), and orthostatic hypotension. It is important to be honest with clients about the potential side effects and manage them proactively, rather than describing the medication as "safe with minimal side effects," which could lead to underestimating the risks.

B. Stop the medication if there is increased urination: Increased urination is not a common or typical side effect of carbidopa/levodopa. In fact, the medication is more likely to cause urinary retention or difficulty urinating in some cases. The client should not stop taking the medication without consulting their healthcare provider. Any urinary changes should be reported, but abrupt discontinuation of the medication is not advised without medical supervision.

C. Change position slowly to prevent orthostatic hypotension: One of the common side effects of carbidopa/levodopa therapy is orthostatic hypotension, which occurs when a person experiences a drop in blood pressure upon standing up. This can lead to dizziness or fainting, increasing the risk of falls. The client should be educated to change positions slowly, such as sitting up slowly and standing up gradually from a lying position, to minimize the risk of orthostatic hypotension. This is a critical aspect of safety and should be emphasized as part of the teaching.

D. Double the dose if a dose is missed at the next scheduled time: Doubling the dose of carbidopa/levodopa if a dose is missed can lead to an overdose, which may cause serious side effects, including dyskinesias or other complications. Clients should be instructed to take the missed dose as soon as they remember, unless it is almost time for the next dose. In that case, they should skip the missed dose and continue with their regular dosing schedule. It is important to never double the dose without guidance from the healthcare provider.

Correct Answer is ["20"]

Explanation

Step-by-Step Solution:

Calculate the volume of medication to administer.

The available medication is 125 mg/5 mL.

We need to administer 500 mg.

To find the volume, we can set up a proportion:

125 mg / 5 mL = 500 mg / x mL

Cross-multiplying:

125x = 500 x 5

Solving for x:

x = (500 x 5) / 125 = 20 mL

A. pH 7.36, Pa02 98 mmHg, PaCO2 27 mmHg, HCO3 16 mEq/L, 02 sat 99% B. pH 7.47, Pa02 91 mmHg, PaCO2 52 mmHg. HCO3 30 mEg/L, 02 sat 96% C. pH 7.45, P302 86 mmHg, PaCO2 56 mmHg, HCO3 28 mEg/L, 02 sat 94% D. PH 7.32, PaO2 88 mmHg. PaCO2 54 mmHg. HCO3 29 mEq/L. 02 sat 94%

Correct Answer is A

Explanation

A. pH 7.36, PaO2 98 mmHg, PaCO2 27 mmHg, HCO3 16 mEq/L, O2 sat 99%: This set of ABG results is consistent with fully compensated metabolic acidosis. pH 7.36: This is within the normal range (7.35-7.45), indicating that compensation has occurred, as the pH has returned to normal levels. PaCO2 27 mmHg: The PaCO2 is low, suggesting that the respiratory system has compensated for the metabolic acidosis by increasing ventilation to excrete CO2, thus reducing the acid load. HCO3 16 mEq/L: The bicarbonate level is low, which is consistent with metabolic acidosis as the primary disturbance. The PaO2 and O2 saturation are normal, indicating adequate oxygenation. Since the pH is within the normal range and the PaCO2 and HCO3 levels reflect the compensatory changes needed to correct the metabolic acidosis, this is a case of fully compensated metabolic acidosis.

B. pH 7.47, PaO2 91 mmHg, PaCO2 52 mmHg, HCO3 30 mEq/L, O2 sat 96%:

This result indicates alkalosis rather than acidosis. The pH is alkalotic (7.47), and PaCO2 is elevated (52 mmHg), which suggests respiratory acidosis as the primary disturbance. The HCO3 is also high (30 mEq/L), which is consistent with metabolic compensation for respiratory acidosis, not for metabolic acidosis. Therefore, this is not consistent with fully compensated metabolic acidosis.

C. pH 7.45, PaO2 86 mmHg, PaCO2 56 mmHg, HCO3 28 mEq/L, O2 sat 94%:

The pH is normal, but PaCO2 is elevated (56 mmHg), indicating respiratory acidosis rather than metabolic acidosis. The HCO3 is also elevated (28 mEq/L), which is consistent with compensation for respiratory acidosis, not metabolic acidosis. This result suggests respiratory acidosis with compensated metabolic alkalosis rather than metabolic acidosis.

D. pH 7.32, PaO2 88 mmHg, PaCO2 54 mmHg, HCO3 29 mEq/L, O2 sat 94%:

The pH of 7.32 indicates acidosis, but it is not within the normal range, so this is not fully compensated. The PaCO2 is elevated (54 mmHg), indicating respiratory acidosis, and the HCO3 is elevated (29 mEq/L), showing metabolic compensation. However, since the pH has not yet returned to normal (it remains acidotic), this is an example of partially compensated respiratory acidosis, not fully compensated metabolic acidosis.

respiratory acidosis, not fully compensated metabolic acidosis.
