A client is admitted to the Emergency Department (ED) with a suspected ST elevation myocardial infarction (STEMI) involving the inferior wall. The nurse anticipates that this client will be immediately scheduled for the cardiac catheterization laboratory. The goal of treatment is to:
Administer antiplatelet and anticoagulant medications to prevent further clot formation.
Relieve the blockage in the coronary artery and restore blood flow to the heart muscle.
Provide pain relief and initiate cardiac rehabilitation.
Stabilize the dient's blood pressure and administer thrombolytic therapy.
The Correct Answer is B
A) Administer antiplatelet and anticoagulant medications to prevent further clot formation:
While antiplatelet and anticoagulant medications are essential in the management of STEMI to reduce the risk of further clot formation, they are not the primary goal of treatment in the immediate phase. These medications are typically administered before or during the procedure (such as during cardiac catheterization) to prevent new clots, but the primary objective is to restore blood flow to the heart muscle through reperfusion therapy, either by angioplasty or thrombolytics.
B) Relieve the blockage in the coronary artery and restore blood flow to the heart muscle:
This is the primary goal of treatment in STEMI. The most urgent intervention for a client with an ST elevation myocardial infarction (STEMI) is to relieve the blockage in the coronary artery and restore blood flow to the ischemic heart muscle. This is typically achieved through percutaneous coronary intervention (PCI) via cardiac catheterization, which involves either angioplasty (ballooning the artery) or stent placement. Restoring blood flow as quickly as possible reduces the extent of myocardial damage, improves the prognosis, and prevents complications like heart failure.
C) Provide pain relief and initiate cardiac rehabilitation:
Pain relief is important in the initial management of STEMI, typically with nitroglycerin and opioids for chest pain. However, the immediate goal in the ED is to address the underlying cause of the chest pain, which is the blockage of blood flow. Cardiac rehabilitation, while essential for long-term recovery, is not the immediate goal of treatment during the acute phase of a STEMI. The primary focus should be on restoring circulation to the affected myocardium.
D) Stabilize the client's blood pressure and administer thrombolytic therapy:
Stabilizing the client’s blood pressure is important, especially if the client is hypotensive, but it is not the main treatment goal. Thrombolytic therapy (clot-busting medications) is an option if PCI is not available or if it needs to be done within a certain time frame; however, the current best practice in STEMI is to perform PCI as soon as possible. Thrombolytics are typically used when PCI is not immediately available, but the ideal treatment is to restore blood flow through catheterization in a timely manner, as it is more effective than thrombolytic therapy at re-opening the blocked artery.

Correct Answer is A
Explanation
A. Suction the client as needed: Suctioning is an essential nursing intervention for clients on mechanical ventilation to maintain effective ventilation. Ventilated clients are at risk for accumulating secretions in the airway, which can obstruct the endotracheal tube or tracheostomy, impairing ventilation and oxygenation. Regular or as-needed suctioning helps to clear secretions, ensuring that the airway remains patent and effective ventilation is maintained. This intervention directly supports the goal of maintaining optimal respiratory function and preventing complications such as atelectasis, pneumonia, or hypoxia.
B. Administer pantoprazole sodium IV: Pantoprazole is a proton pump inhibitor used to decrease stomach acid, typically to prevent stress ulcers in critically ill patients. While this is an important aspect of care for preventing gastrointestinal complications in ventilated patients, it does not directly support ventilation. Therefore, administering pantoprazole is not as directly related to ensuring effective ventilation as suctioning or other respiratory interventions.
C. Apply sequential compression device (SCD): While applying an SCD is important for preventing deep vein thrombosis (DVT) and promoting circulation in immobile patients, it does not directly address the client's ventilation or respiratory function. This intervention is more relevant for preventing venous thromboembolism, not for managing ventilation or airway clearance.
D. Perform oral care with chlorhexidine: Oral care with chlorhexidine is an important practice to reduce the risk of ventilator-associated pneumonia (VAP) and promote overall oral hygiene. It helps decrease the colonization of bacteria in the mouth and reduces the risk of infection. However, while oral care is an essential component of care for a ventilated patient, suctioning directly addresses the goal of effective ventilation by maintaining airway patency, making it the most immediate and relevant intervention for supporting ventilation.
Correct Answer is B
Explanation
A. Guidewire-induced dysrhythmia: Guidewire-induced dysrhythmia can occur if the guidewire or catheter irritates the heart during insertion, particularly when the catheter is placed in the central venous system. While this can lead to arrhythmias, it is typically more immediate and occurs during the procedure itself. The symptoms of dysrhythmia (e.g., irregular heartbeat) would more likely present right after insertion or during the manipulation of the guidewire. The signs of restlessness, JVD, and tachycardia observed 30 minutes after placement are more suggestive of a pneumothorax than of a guidewire-induced dysrhythmia.
B. Pneumothorax: Pneumothorax is a potential complication of central venous catheter (CVC) placement, particularly when the catheter is inserted into the subclavian vein. The right subclavian vein is located near the apex of the lung, so inadvertent puncture of the lung during catheter placement can lead to air entering the pleural space, causing a pneumothorax. The symptoms of pneumothorax may include restlessness, tachycardia, jugular vein distention (JVD), and respiratory distress. A heart rate of 120 beats per minute is consistent with tachycardia due to hypoxia or distress, and JVD can be a sign of increased intrathoracic pressure or impaired venous return, which occurs with a pneumothorax. These symptoms warrant immediate assessment for pneumothorax, which can be confirmed with a chest x-ray.
C. Pulmonary infarction: Pulmonary infarction occurs when a blockage in the pulmonary arteries prevents blood flow to lung tissue, resulting in tissue death. This can be caused by a pulmonary embolism or other issues, but it is not a typical complication of central venous catheter placement. The symptoms described (restlessness, JVD, and tachycardia) are more consistent with a pneumothorax than a pulmonary infarction, which would likely cause chest pain, hemoptysis, or dyspnea rather than these signs.
D. Venous thrombosis: While venous thrombosis (or clot formation) is a potential complication of central venous catheter placement, it typically manifests as swelling, redness, or pain at the catheter insertion site, rather than with the systemic symptoms of restlessness, tachycardia, and JVD. Venous thrombosis could cause some of the described symptoms in the long term, but it is less likely to be the cause of acute symptoms 30 minutes post-procedure. The immediate concern in this case is more likely to be pneumothorax, which can occur more suddenly and cause these symptoms.Top of FormBottom of Form
