A nurse is providing discharge teaching to a client who will be taking levodopa/carbidopa for Parkinson's disease. Which of the following statements by the client indicates a need for further teaching?
I will report any unusual movements or behaviors to my healthcare provider."
I may experience nausea while taking this medication."
I will take this medication with a high-protein meal."
I will avoid sudden changes in position to prevent dizziness or falls."
The Correct Answer is C
A. "I will report any unusual movements or behaviors to my healthcare provider."
This statement is correct and indicates that the client understands the potential side effects of levodopa/carbidopa. The medication can cause dyskinesia (uncontrolled movements) and other behavioral changes, so the client should report these symptoms to their healthcare provider for possible adjustment of the treatment plan.
B. "I may experience nausea while taking this medication."
This is also correct. Nausea is a common side effect of levodopa/carbidopa, especially when starting the medication. Taking it with food may help reduce this side effect, but some clients may still experience nausea.
C. "I will take this medication with a high-protein meal."
This statement is incorrect. Levodopa is absorbed best on an empty stomach or with a low-protein meal. Protein can interfere with the absorption of levodopa because amino acids (found in proteins) compete with levodopa for absorption across the blood-brain barrier. Therefore, it's recommended that levodopa/carbidopa be taken either 30 minutes before or 1 hour after meals, especially those high in protein.
D. "I will avoid sudden changes in position to prevent dizziness or falls."
This statement is correct. Levodopa/carbidopa can cause orthostatic hypotension (a sudden drop in blood pressure when standing up), which increases the risk of dizziness and falls. The client should be advised to change positions slowly and use support when rising from a sitting or lying position to avoid injury.

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.
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
