A nurse is teaching a client newly diagnosed with a seizure disorder about phenytoin sodium therapy. What information should the nurse stress regarding the client stopping the drug suddenly? The drug should not be stopped abruptly because:
hypoglycemic event often develops
physical dependency on the drug develops over time.
a heart block is likely to develop.
status epileptic us may develop
The Correct Answer is D
A) Hypoglycemic event often develops:
Phenytoin is an anticonvulsant, and while it can affect glucose metabolism, hypoglycemia is not a typical consequence of abruptly stopping the drug. This is not a primary concern when discontinuing phenytoin therapy. Hypoglycemia is more commonly associated with medications like insulin or sulfonylureas, not anticonvulsants like phenytoin.
B) Physical dependency on the drug develops over time:
Phenytoin does not cause physical dependence in the way that some other substances (e.g., alcohol, opioids) can. While the body can become used to a medication over time, and withdrawal symptoms can occur, the risk of physical dependence is not the main reason why phenytoin should not be stopped suddenly.
C) A heart block is likely to develop:
Phenytoin is known to have effects on cardiac conduction, and it can cause heart rhythm disturbances like bradycardia or a prolonged PR interval, especially with toxicity. However, the risk of a heart block developing due to abrupt discontinuation of phenytoin is not the primary concern.
D) Status epilepticus may develop:
The most serious risk of suddenly stopping phenytoin, or any anticonvulsant, is the potential for status epilepticus. Status epilepticus is a medical emergency where seizures occur continuously without recovery in between, which can be life-threatening. Abruptly discontinuing phenytoin can lead to a rebound increase in seizure activity, which can result in status epilepticus.

Correct Answer is C
Explanation
A) Intestines:
While abdominal trauma can affect the intestines, Kehr's sign, Cullen's sign, and Gray Turner's sign are more commonly associated with damage to the spleen rather than the intestines. Kehr's sign, in particular, is a hallmark of splenic injury, with pain referred to the left shoulder due to diaphragmatic irritation from blood in the peritoneum.
B) Liver:
Liver injuries often present with right upper quadrant pain, jaundice, and elevated liver enzymes. While liver injuries can cause internal bleeding, Cullen's and Gray Turner's signs are more closely associated with retroperitoneal bleeding from the spleen rather than liver injuries. Kehr's sign, which is left-sided shoulder pain, would not typically indicate a liver injury.
C) Spleen:
The spleen is the most likely abdominal organ affected in this case due to the left-sided rib fractures. When the spleen is injured (often as a result of blunt trauma), it can cause intraperitoneal hemorrhage. This bleeding can irritate the diaphragm, leading to Kehr's sign, which presents as left shoulder pain. Additionally, Cullen's sign (periumbilical bruising) and Gray Turner's sign (flank bruising) are indicative of retroperitoneal bleeding, which can occur with splenic rupture or laceration.
D) Stomach:
While stomach injuries can occur with blunt abdominal trauma, they are less likely to cause the signs and symptoms seen in this patient (Kehr's, Cullen's, and Gray Turner's signs). Stomach trauma typically leads to pain and potential perforation, but it doesn't often cause the peritoneal bleeding patterns seen with splenic injuries.
Correct Answer is ["D","E"]
Explanation
A) Pneumonia: Pneumonia is a direct cause of ARDS, as it involves direct inflammation and infection of the lung tissue, leading to impaired oxygen exchange and damage to the alveolar-capillary membrane. It results in fluid accumulation in the lungs, which is a key characteristic of ARDS.
B) Drowning: Drowning is another direct cause of ARDS. It involves the aspiration of water into the lungs, which directly damages lung tissue, causing pulmonary edema and impaired oxygenation.
C) Aspiration: Aspiration of food, liquid, or vomit into the lungs is also a direct cause of ARDS. The aspirated material can lead to chemical pneumonia, bacterial infection, and inflammation of the lungs, which in turn causes ARDS.
D) Sepsis: Sepsis is an indirect cause of ARDS. It can lead to widespread inflammation throughout the body, including the lungs, through the release of inflammatory mediators (cytokines, interleukins, etc.). These systemic inflammatory responses can increase capillary permeability in the lungs, causing fluid to leak into the alveoli, which leads to ARDS.
E) Blood Transfusion: Blood transfusion, particularly when associated with transfusion-related acute lung injury (TRALI), is an indirect cause of ARDS. TRALI is a serious complication that can result from receiving blood products, where the transfused blood causes an immune response leading to pulmonary damage. It indirectly triggers inflammation and fluid buildup in the lungs, contributing to ARDS.
