A nurse is assisting with the care of a client who is 24 hours following a vaginal birth. Which of the following findings should the nurse report to the RN?

A fecal occult blood test (FOBT) is used to detect hidden blood in the stool, which may indicate gastrointestinal bleeding from conditions such as ulcers, polyps, or colorectal cancer. Proper specimen collection is essential to ensure accuracy and reduce false-positive or false-negative results. Patient education focuses on correct sampling techniques, dietary and medication restrictions, and avoiding contamination from non-gastrointestinal sources of blood. Multiple samples are typically required to improve diagnostic reliability.

Rationale:
A. Collecting samples from three separate bowel movements demonstrates correct understanding because FOBT accuracy improves when multiple stool specimens are tested over different days. This helps account for intermittent bleeding and increases the likelihood of detecting occult blood associated with conditions such as Colorectal cancer. Consistent sampling reduces diagnostic error and improves screening sensitivity.

B. Continuing to take aspirin daily for pain is incorrect because aspirin can increase gastrointestinal bleeding and lead to false-positive test results. It inhibits platelet aggregation, which may cause occult bleeding unrelated to underlying pathology. Patients are typically instructed to avoid medications such as NSAIDs before testing.

C. Collecting samples when hemorrhoids are bleeding is incorrect because external bleeding from hemorrhoids can contaminate the stool sample and produce a false-positive result. The test is intended to detect hidden (occult) gastrointestinal bleeding, not visible rectal bleeding from external sources. Active hemorrhoidal bleeding should be reported before specimen collection.

D. Continuing to eat red meat is incorrect because red meat can cause false-positive results due to the presence of heme compounds. Dietary restrictions are often recommended prior to testing to improve accuracy. Patients are usually advised to avoid red meat and certain peroxidase-containing foods before sample collection.

Monitoring during blood transfusion requires early recognition of adverse reactions that may range from mild febrile responses to life-threatening immune-mediated emergencies. Reactions such as urticaria, bronchospasm, and wheezing indicate a systemic hypersensitivity response involving release of histamine and other inflammatory mediators. In the context of a transfusion, these findings suggest a severe allergic reaction that can rapidly progress to respiratory compromise and shock. Immediate identification and intervention are critical to prevent deterioration.

Rationale:
A. Acute hemolytic transfusion reactions typically present with fever, chills, back or flank pain, hypotension, hemoglobinuria, and a sense of impending doom. These reactions result from ABO incompatibility leading to destruction of transfused red blood cells. Urticaria and wheezing are not the primary features, making this option less consistent with the presentation.

B. Febrile non-hemolytic reactions usually present with low-grade fever and chills due to cytokine release from donor leukocytes. They do not typically involve respiratory symptoms such as wheezing or cutaneous manifestations like urticaria. This reaction is generally mild and not associated with airway compromise.

C. Anaphylactic transfusion reaction is characterized by urticaria, wheezing, bronchospasm, hypotension, and potentially airway obstruction due to severe IgE-mediated hypersensitivity. In response to exposure to allergenic components in blood products, mast cell degranulation leads to histamine release causing both skin and respiratory symptoms. This presentation requires immediate cessation of transfusion and emergency intervention.

D. Circulatory overload (TACO) presents with dyspnea, hypertension, crackles, and signs of pulmonary edema due to volume excess. It does not typically cause urticaria or wheezing as primary manifestations. The underlying issue is fluid overload rather than immune-mediated hypersensitivity.
