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. Petechiae are tiny, pinpoint, red or purple spots on the skin or mucous membranes, caused by bleeding under the skin. While petechiae can indicate bleeding, they are not specific to HIT and can occur due to various reasons, including low platelet count or coagulation disorders. They do not necessarily indicate thrombotic complications associated with HIT.
B. This hemoglobin level is within the normal range for adults and does not directly correlate with HIT. However, it is important to monitor hemoglobin levels in patients with HIT due to the risk of bleeding and thrombosis.
C. Bleeding gums can occur due to various reasons, including gum disease or thrombocytopenia (low platelet count). In HIT, the concern is not just bleeding but also the paradoxical risk of thrombosis despite low platelet counts. Bleeding from mucosal surfaces can indicate underlying thrombocytopenia but does not specifically highlight the thrombotic risk of HIT.
D. This symptom is concerning for deep vein thrombosis (DVT), which is a thrombotic complication associated with HIT. HIT predisposes patients to thrombosis due to the formation of antibodies against

platelet factor 4/heparin complexes, leading to platelet activation and clot formation. DVT is a serious complication that requires immediate intervention to prevent pulmonary embolism (PE).

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.
