A nurse is caring for a patient with a diagnosis of sepsis who is on a ventilator in the intensive care unit. To reduce the risk of developing a physiologic stress ulcer, the nurse should anticipate an order to administer which medication?
Methylprednisolone
Enoxaparin
Pantoprazole
Ibuprofen
The Correct Answer is C
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.

Correct Answer is D
Explanation
A. Guillain-Barre Syndrome is not a contagious disease. It is an autoimmune disorder that occurs when the immune system mistakenly attacks the peripheral nerves. GBS is not spread through respiratory droplets or any other form of infection transmission.
B. Guillain-Barre Syndrome causes demyelination in the peripheral nervous system, not the central nervous system. The central nervous system includes the brain and spinal cord, whereas the peripheral nervous system comprises the nerves outside the brain and spinal cord.
C. Guillain-Barre Syndrome is not a genetic disorder. It is considered an autoimmune condition that can be triggered by an infection or other environmental factors. While there may be genetic predispositions that affect susceptibility to autoimmune conditions, GBS itself is not classified as a genetic disorder.
D. Guillain-Barre Syndrome primarily affects the peripheral nervous system. It involves an immune- mediated attack on the peripheral nerves, leading to symptoms such as muscle weakness, tingling, and loss of reflexes.
Correct Answer is A
Explanation
A. Floaters and flashes of light are classic symptoms of retinal detachment. When the retina begins to detach from the underlying tissue, it can cause these visual disturbances. Floaters are small, shadowy shapes that move across the field of vision, while flashes of light can occur due to the retina being stretched or pulled.
B. Cataracts primarily cause blurred vision, difficulty seeing at night, and sensitivity to light, rather than floaters or flashes of light.
C. AMD generally affects central vision and can cause symptoms such as distorted vision, difficulty seeing in low light, and a loss of central vision. While AMD can cause vision changes, it is not typically associated with seeing floaters and flashes of light.
D. Open-angle glaucoma usually progresses slowly and is often asymptomatic in its early stages. It primarily affects peripheral vision, leading to a gradual loss of vision in the periphery.
