A nurse is caring for a client who has myasthenia gravis which has not responded to medication treatments. Which of the following surgeries can treat myasthenia gravis?

A. PSA levels themselves do not indicate a gene mutation. Elevated PSA levels are primarily associated with prostate conditions rather than genetic mutations. While certain genetic mutations can predispose individuals to prostate cancer, PSA alone does not diagnose genetic mutations.
B. Elevated PSA levels can indicate the possibility of prostate cancer, but further testing is necessary to confirm the diagnosis. Additional tests may include a digital rectal exam (DRE), imaging studies (such as ultrasound or MRI), and a prostate biopsy.
C. Elevated PSA levels can suggest prostate cancer, but they do not definitively diagnose it. Prostate cancer can only be confirmed through a biopsy that identifies cancerous cells in the prostate tissue.
D. BPH is a non-cancerous enlargement of the prostate gland that commonly occurs in older men. While BPH can cause urinary symptoms similar to prostate cancer, elevated PSA levels are not typically associated with BPH alone. PSA elevation is more specific to prostate cancer but can also occur with other prostate conditions.

A. Defibrillation is not typically indicated for atrial fibrillation. Atrial fibrillation involves disorganized electrical activity in the atria rather than a shockable rhythm like ventricular fibrillation or ventricular tachycardia. Therefore, emergency defibrillation is not appropriate for a client with persistent atrial fibrillation.
B. CABG is a surgical procedure used to improve blood flow to the heart muscle by bypassing blocked coronary arteries. It is primarily indicated for clients with significant coronary artery disease that cannot be managed effectively with medications or less invasive
C. Anticoagulant therapy, such as with medications like warfarin or direct oral anticoagulants (DOACs), is crucial for clients with atrial fibrillation. AFib predisposes individuals to an increased risk of stroke due to the potential formation of blood clots in the atria. Anticoagulants help prevent clot formation and reduce the risk of stroke.
D. Diuretics are medications that increase urine output and are often used to manage fluid overload or congestion in conditions such as heart failure or volume overload. However, diuretic therapy alone does not address the underlying rhythm abnormality of atrial fibrillation.
