Autonomic dysreflexia is characterized by:

Hypertension, bradycardia, and headache.

Hypotension and shock.

Extreme pain below the level of injury.

Pallor and vasodilation above the level of injury.

Answer and Explanation

The Correct Answer is A

Choice A reason: Autonomic dysreflexia is a condition that occurs in individuals with spinal cord injuries, typically at or above the T6 level. It is characterized by a sudden and severe increase in blood pressure (hypertension), accompanied by a slowed heart rate (bradycardia) and severe headache. This condition results from an exaggerated autonomic response to stimuli below the level of the spinal cord injury, such as a distended bladder or bowel, leading to the release of catecholamines and subsequent vasoconstriction.

Choice B reason: Hypotension and shock are not characteristic of autonomic dysreflexia. Instead, autonomic dysreflexia involves hypertension. Hypotension and shock are more commonly associated with conditions such as spinal shock or severe blood loss, not the autonomic crisis seen in autonomic dysreflexia.

Choice C reason: Extreme pain below the level of injury can occur in individuals with spinal cord injuries, but it is not a hallmark of autonomic dysreflexia. The condition is primarily marked by the triad of hypertension, bradycardia, and headache. Pain below the level of injury may be related to other complications of spinal cord injury but does not define autonomic dysreflexia.

Choice D reason: Pallor and vasodilation above the level of injury are not typical features of autonomic dysreflexia. In fact, above the level of injury, individuals may experience vasoconstriction and flushing due to the altered autonomic responses. The key symptoms of autonomic dysreflexia are hypertension, bradycardia, and headache.

Correct Answer is B

Explanation

Choice A reason: Abdominal pain and rectal bleeding are not the primary signs of a bowel obstruction. Rectal bleeding could be indicative of other gastrointestinal issues such as hemorrhoids, diverticulosis, or colorectal cancer. While abdominal pain is a symptom of bowel obstruction, rectal bleeding is not typically associated with it.

Choice B reason: The primary symptoms of bowel obstruction include abdominal distention, pain, inability to have a bowel movement, and nausea/vomiting. When a bowel obstruction occurs, the normal movement of intestinal contents is blocked, leading to a buildup of contents and gas. This results in abdominal distention and pain. The blockage also prevents the passage of stool and gas, causing constipation or inability to have a bowel movement. Nausea and vomiting are common as the digestive system tries to expel the contents that cannot pass through the obstruction.

Choice C reason: Dehydration, back pain, and fever are not the hallmark symptoms of bowel obstruction. While dehydration can occur due to vomiting and reduced intake, back pain is not commonly associated with bowel obstruction. Fever may indicate an infection or other complications but is not a primary symptom of bowel obstruction.

Choice D reason: Diarrhea and excessive thirst are not typical signs of bowel obstruction. In fact, bowel obstruction usually leads to constipation or the inability to pass stool rather than diarrhea. Excessive thirst could be a sign of dehydration but is not specific to bowel obstruction.

A. Risk for infection B. Need for sunblock C. Need for an eye examination D. Risk for developing esophagitis

Correct Answer is A

Explanation

Choice A reason: Methotrexate is an immunosuppressive drug commonly used to treat rheumatoid arthritis. One of the most important topics to address when teaching a patient about methotrexate is the risk for infection. Methotrexate can suppress the immune system, making patients more susceptible to infections. Patients should be educated on the signs and symptoms of infection, the importance of maintaining good hygiene, avoiding contact with sick individuals, and reporting any signs of infection to their healthcare provider promptly. This helps in early detection and management of infections, which can be severe in immunocompromised patients.

Choice B reason: The need for sunblock is important for patients taking certain medications that cause photosensitivity, but methotrexate is not typically associated with a high risk of photosensitivity. While sun protection is generally advisable, it is not the most critical teaching point for methotrexate.

Choice C reason: The need for an eye examination is crucial for patients taking medications like hydroxychloroquine, which can affect the eyes. However, methotrexate does not commonly require routine eye examinations, making this a lower priority in patient education.

Choice D reason: The risk for developing esophagitis is more relevant for patients taking medications that can cause irritation or damage to the esophagus, such as bisphosphonates. While methotrexate can cause gastrointestinal side effects, esophagitis is not a primary concern, making this less critical compared to the risk of infection.
