The patient is admitted with upper GI bleeding following an episode of forceful vomiting due to excessive alcohol intake. The nurse suspects a Mallory-Weiss tear. Which of the following is true of a Mallory-Weiss tear?

A. Chemotherapy often requires multiple infusions over a long period, and a CVAD provides a reliable and convenient access point for these treatments. It allows for the continuous or intermittent administration of chemotherapy drugs, which are often irritating to veins and require precise dosing.
B. While CVADs are used for administering chemotherapy and other treatments, they are not typically used to implant radioactive material for internal radiation (brachytherapy).
C. While CVADs reduce the need for repeated venipunctures and can help manage the complications of frequent injections, they do not eliminate the risk of infection. CVADs can themselves become a source of infection if not properly maintained, as they are open to the external environment.
D. The placement of a CVAD does not directly affect the side effects of chemotherapy, such as nausea and vomiting. The CVAD’s role is primarily related to the administration of medications and access to blood vessels.

A. Methylprednisolone is a corticosteroid used to reduce inflammation and suppress the immune system. While corticosteroids are sometimes used in critical care settings, they are not specifically used to prevent stress ulcers. In fact, corticosteroids can increase the risk of gastrointestinal bleeding and may require additional measures to protect the stomach lining.
B. Enoxaparin is a low molecular weight heparin (LMWH) used primarily for the prevention of deep vein thrombosis (DVT) and pulmonary embolism (PE). It works as an anticoagulant, preventing blood clots. While enoxaparin is important for preventing thromboembolic events in critically ill patients, it does not specifically address the prevention of stress ulcers.
C. Pantoprazole is a proton pump inhibitor (PPI) that reduces gastric acid production by inhibiting the proton pumps in the stomach lining. PPIs are commonly used to prevent and treat stress ulcers because they help decrease gastric acid secretion, thereby reducing the risk of ulcer formation and bleeding. This makes pantoprazole the appropriate medication to administer to prevent physiologic stress ulcers in a patient with sepsis on a ventilator.
D. Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) that is used for pain relief and inflammation. NSAIDs can actually increase the risk of gastrointestinal bleeding and ulceration, especially in critically ill patients.
