A nurse is teaching a prenatal class about infection prevention at a community center.
Which of the following statements by a client indicates an understanding of the teaching?

Choice A rationale:

Allergic transfusion reactions are characterized by symptoms such as hives, itching, and shortness of breath. While allergic reactions can cause discomfort, they do not typically present with the symptoms described in the scenario, such as chills, headache, low-back pain, and chest tightness.

Choice B rationale:

Febrile nonhemolytic transfusion reactions are characterized by fever and chills, but they do not usually cause headache, low-back pain, or chest tightness. These reactions occur due to antibodies against donor leukocytes or platelets.

Choice C rationale:

Acute hemolytic transfusion reactions occur when there is a mismatch in blood type between the donor and recipient, leading to rapid destruction of transfused red blood cells. This reaction can cause symptoms such as chills, fever, low-back pain, chest tightness, and hemoglobinuria (presence of hemoglobin in the urine) It is a medical emergency that requires immediate cessation of the transfusion, supportive care, and treatment for potential complications such as acute kidney injury.

Choice D rationale:

Bacterial transfusion reactions occur due to bacterial contamination of the blood product. These reactions can cause symptoms such as fever, chills, hypotension, and shock. While bacterial transfusion reactions can be serious, the symptoms described in the scenario, including headache and low-back pain, are not typically associated with this type of reaction.

A. "Try using an abdominal support belt." - An abdominal support belt is recommended to provide support to the growing abdomen and can help alleviate backaches that are common during pregnancy.

B. "Take hot showers to help relieve itching." - This statement is incorrect. Hot showers can actually worsen itching and dry out the skin. Lukewarm showers are recommended instead.
