The factors of Virchow's triad can result in:

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.

Choice A reason: Red-orange colored bodily secretions are a well-known side effect of the medication rifampin, not isoniazid. Rifampin is often used in combination therapy for tuberculosis, and it can cause the patient's urine, sweat, tears, and other bodily fluids to become red or orange in color. However, this specific side effect is not associated with isoniazid, which is used as a part of the treatment regimen for tuberculosis but does not cause this particular discoloration.

Choice B reason: Tingling sensation in fingers and toes, also known as peripheral neuropathy, is a recognized side effect of isoniazid. Isoniazid can interfere with vitamin B6 (pyridoxine) metabolism, leading to a deficiency. This deficiency causes neuropathy, resulting in tingling, numbness, or burning sensations in the extremities. To prevent this side effect, patients receiving isoniazid are often prescribed vitamin B6 supplements. These supplements help prevent the development of peripheral neuropathy by ensuring adequate levels of vitamin B6 in the body, which is essential for nerve health.

Choice C reason: Difficulty distinguishing the color red from green, or color blindness, is not a side effect of isoniazid. Color vision deficiency is not associated with the use of isoniazid. Other medications, such as ethambutol, used in tuberculosis treatment can cause visual disturbances, including changes in color vision, but isoniazid does not typically affect color perception. Isoniazid's primary neurological side effect is peripheral neuropathy rather than issues with color vision.

Choice D reason: Light sensitivity, or photophobia, is not a common side effect of isoniazid. This symptom is more likely to be associated with other conditions or medications that affect the eyes or central nervous system. Isoniazid's side effects are primarily related to liver toxicity and peripheral neuropathy, rather than causing sensitivity to light. Therefore, experiencing photophobia would not be directly attributable to isoniazid therapy and would require further investigation to determine the underlying cause.
