Question 1 of 5
Which of the ff is the most severe complication among clients with allergies, regardless of type?
Correct Answer: B
Rationale: Among clients with allergies, regardless of type, anaphylactic shock and angioneurotic edema are the most severe complications. Anaphylactic shock is a severe, potentially life-threatening allergic reaction that can occur rapidly and affect multiple organ systems, leading to a sudden drop in blood pressure and difficulty breathing. Angioneurotic edema, also known as angioedema, is another serious allergic reaction that involves swelling of the deep layers of the skin, often around the eyes and lips, but can also affect the throat and other areas, potentially leading to airway obstruction. These complications require immediate medical attention, including the administration of epinephrine and other interventions to stabilize the client.
Question 2 of 5
When administering a blood transfusion to a client with multiple traumatic injuries, the nurse monitors closely for evidence of a transfusion reaction. Shortly after the transfusion begins, the client complains of chest pain, nausea and itching. When urticarial, tachycardia, and hypotension develop, the nurse stops the transfusion and notifies the physician. The nurse suspects which type of hypersensitivity reaction?
Correct Answer: A
Rationale: The symptoms described in the scenario, such as chest pain, nausea, itching, urticaria, tachycardia, and hypotension, are indicative of an immediate hypersensitivity reaction, also known as a Type I hypersensitivity reaction. This type of reaction is triggered by the release of histamine and other inflammatory mediators from mast cells and basophils. Symptoms can range from mild to severe and can manifest rapidly after exposure to the allergen, in this case, the blood transfusion. Common manifestations include skin reactions (e.g., itching, urticaria), respiratory symptoms (e.g., chest pain, wheezing), cardiovascular changes (e.g., tachycardia, hypotension), and gastrointestinal symptoms (e.g., nausea, vomiting).
Question 3 of 5
While monitoring a client for the development of disseminated intravascular coagulation (DIC), the nurse should take note of what assessment parameters?
Correct Answer: A
Rationale: When monitoring a client for the development of disseminated intravascular coagulation (DIC), it is important to assess key parameters that can indicate abnormal clotting and bleeding tendencies. The platelet count is essential as DIC can lead to thrombocytopenia (low platelet count). Prothrombin time (PT) and partial thromboplastin time (PTT) are coagulation tests that evaluate the extrinsic and intrinsic pathways of blood clotting, respectively. Prolongation of these times can indicate abnormal coagulation processes seen in DIC. Monitoring these parameters allows healthcare providers to assess and manage DIC promptly to prevent further complications.
Question 4 of 5
During chemotherapy for lymphocytic leukemia, a client develops abdominal pain, fever, and "horse barn" smelling diarrhea. It would be most important for the nurse to advise the physician to order:
Correct Answer: B
Rationale: The client's symptoms of abdominal pain, fever, and "horse barn" smelling diarrhea are concerning for Clostridium difficile infection, especially in the setting of receiving chemotherapy which can weaken the immune system. Clostridium difficile is a bacteria that can cause severe diarrhea and inflammation of the colon. Testing for Clostridium difficile in the stool is crucial for diagnosing the infection and guiding appropriate treatment. Therefore, advising the physician to order a stool test for Clostridium difficile would be the most important in this scenario to confirm the diagnosis and initiate appropriate management.
Question 5 of 5
A clinical nurse specialist (CNS) is orienting a new graduate registered nurse to an oncology unit where blood product transfusions are frequently administered. In discussing ABO compatibility, the CNS presents several hypothetical scenarios. A well-informed new graduate would know the greatest likelihood of an acute hemolytic reaction would occur when giving:
Correct Answer: B
Rationale: The greatest likelihood of an acute hemolytic reaction occurs when there is mismatch in the ABO blood group system, specifically when the recipient's plasma contains antibodies against the donor's red blood cells. In this scenario, giving O-positive blood to an A-positive client presents the highest risk because the A-positive client has anti-B antibodies in their plasma, which can attack the B antigens present on the O-positive donor red blood cells. This mismatch can lead to rapid destruction of the transfused red blood cells, causing an acute hemolytic reaction. It is crucial to ensure ABO compatibility to prevent such life-threatening reactions during blood product transfusions.
