The nurse monitors the client in the immediate hours following an anterior-lateral wall myocardial infarction for the development of:
a systolic murmur
ventricular dysrhythmias
a pericardial friction rub
renal insufficiency
The Correct Answer is B
A. A systolic murmur: A systolic murmur is often associated with valvular heart disease, particularly mitral regurgitation, which can sometimes result from papillary muscle dysfunction after a myocardial infarction. However, a systolic murmur is not a typical or immediate complication following an anterior-lateral wall MI. The focus in the early hours after an MI should be on more acute complications, such as dysrhythmias and hemodynamic stability, rather than a murmur, which may develop more gradually over time.
B. Ventricular dysrhythmias: Ventricular dysrhythmias are one of the most common and life-threatening complications in the immediate hours following an acute myocardial infarction (MI), especially with an anterior-lateral wall MI. These dysrhythmias occur due to the electrical disturbances caused by myocardial injury and ischemia. The heart muscle becomes more susceptible to abnormal electrical activity after the infarction, and monitoring for ventricular tachycardia or fibrillation is crucial. These arrhythmias can lead to sudden cardiac arrest, which is why they are a high priority for monitoring in the immediate post-MI period.
C. A pericardial friction rub: A pericardial friction rub is a sign of pericarditis, which can occur after an MI, particularly several days to a week later, rather than in the immediate post-MI period. While pericarditis is a possible complication of MI, it is less likely to present immediately after the infarction, especially in the first few hours. The nurse should monitor for pericarditis, but it is not as high a priority as dysrhythmias during the first hours after MI.
D. Renal insufficiency: While renal insufficiency can develop as a result of poor perfusion or shock following a myocardial infarction, it is not one of the most immediate or common complications to watch for in the first hours after an anterior-lateral MI. The primary concern in this acute phase is monitoring for cardiovascular complications, such as dysrhythmias, rather than renal function. Renal insufficiency would be a secondary concern, particularly if the patient is hypotensive or experiencing other signs of multi-organ involvement.

Correct Answer is B
Explanation
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.
Correct Answer is C
Explanation
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.
