The nurse is admitting a client who is on a ventilator. The client has a medical diagnosis of acute respiratory distress syndrome (ARDS). Which infection control guideline is of greatest importance?

A. Remove the BIPAP mask:
While removing the BIPAP mask may seem like a reasonable action to take in response to vomiting, it is not the immediate priority. The most urgent issue in this scenario is preventing aspiration and maintaining the client’s airway. Removing the mask may be necessary later for resuscitation or further interventions, but the first priority is protecting the airway and preventing aspiration pneumonia, which is best done by positioning the client appropriately. BIPAP should only be removed if the client's airway cannot be maintained, or if there is a need for intubation or other advanced airway management.

B. Assist the client to a side-lying position: When a client on BIPAP (bi-level positive airway pressure) begins to vomit, the priority nursing intervention is to protect the airway and prevent aspiration. The side-lying position is the most effective way to prevent aspiration of vomit into the lungs, as it allows the contents to drain from the mouth and reduces the risk of airway obstruction. This position also ensures that the client’s airway remains open while minimizing the risk of choking or aspiration pneumonia. The side-lying position is crucial in managing nausea and vomiting in clients on non-invasive ventilation, like BIPAP.

C. Administer ondansetron intravenously (IV):
Ondansetron is an effective antiemetic and may be appropriate to administer if the client’s nausea continues. However, nausea and vomiting are secondary concerns in this situation compared to airway protection. The first priority is to position the client to prevent aspiration of vomit. Once the client is in a safe position, ondansetron may be administered to address the nausea and prevent further vomiting, but this does not address the immediate airway risk.

D. Notify the primary care provider:
While notifying the healthcare provider may be necessary at some point, the priority nursing intervention is to manage the immediate concern of the client vomiting while on BIPAP. The primary concern at this point is protecting the airway and preventing aspiration. The healthcare provider may need to be informed about the situation, but the nurse must first ensure the client's safety through appropriate positioning.

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.
