Obtaining a stat chest x-ray is important if catheter misplacement is suspected, but in this situation, ensuring the accuracy of the pressure reading through proper leveling and zeroing is the priority.

Increasing supplemental oxygen is unnecessary given the patient’s stable oxygen saturation and normal respiratory status.

While notifying the provider is important, ensuring the accuracy of the pressure reading by leveling and zeroing the catheter should be done first.

While certification enhances professional credibility, it does not guarantee the absence of mistakes.

Preparing for graduate school is not the primary purpose of certification.

Certification may contribute to a facility's pursuit of Magnet status, but its primary purpose is to validate nursing expertise.

This response is dismissive of the patient's concerns and does not address the underlying issue of the patient's misunderstanding of cardiac rehabilitation.

This response defers to the physician without providing the patient with helpful information.

While true, this statement does not address the patient’s concern about the irreversibility of heart damage.

Slight bloody drainage is a common finding and typically does not require immediate action.

A dressing beginning to lift should be addressed to maintain a sterile environment but is not an emergency.

Slight redness at the insertion site may indicate mild irritation or early signs of infection, but it does not require immediate intervention compared to the potential vascular or nerve compromise suggested by numbness and tingling.

An electrophysiology study assesses the electrical activity of the heart but does not evaluate heart function or chamber size.

A 12-lead electrocardiogram records the electrical activity of the heart but does not provide detailed information on heart function or chamber size.

Cardiac catheterization is an invasive procedure used to assess coronary artery disease and other structural heart conditions but is not the primary study for evaluating heart function and chamber size.

CK-MB is a cardiac enzyme that rises in response to myocardial injury, but it is less specific and takes longer to rise than troponin.

BNP is associated with heart failure, not myocardial infarction.

Myoglobin is an early marker but is non-specific, as it rises with any muscle damage.

Spironolactone is a potassium-sparing diuretic, so it would not cause hypokalemia.

Metoprolol is a beta-blocker and does not directly affect potassium levels.

Nitroglycerin is a vasodilator and does not affect potassium levels.

While a CVP catheter might be in place for an extended period, its purpose is not directly related to heart healing.

The CVP catheter does not extend into the left ventricle; it is typically positioned in the superior vena cava or right atrium.

The CVP catheter may have multiple lumens for administering fluids, but its primary purpose is hemodynamic monitoring, not just providing IV access.

A coronary artery bypass graft is used to treat coronary artery disease but is not typically indicated for end-stage heart failure.

Percutaneous coronary intervention is also used for coronary artery disease, not for improving quality of life in terminal heart failure.

This option dismisses potential interventions that could improve quality of life, such as an LVAD.

Nitroglycerin is used to treat chest pain, not specifically to prevent heart failure exacerbations.

Assessment of the apical pulse is important, but monitoring weight is more directly related to managing heart failure.

Compliance with diuretic therapy is important, but recognizing early signs of fluid retention, such as rapid weight gain, is crucial for preventing exacerbations.
