The nurse is administering Penicillin to a patient who has tested positive for strep throat. The nurse knows to look for which of the following adverse e昀昀ects as a sign of an acute allergic reaction?

Correct Answer: C

Rationale: An acute allergic reaction to Penicillin can present with symptoms such as skin rash or hives. This is a common sign of an allergic reaction and can indicate the patient is having an adverse response to the medication. It is essential for the nurse to monitor the patient closely for any signs of allergic reactions, including hives, as they can quickly progress to more severe reactions such as anaphylaxis. Other adverse effects listed in the choices, such as blurred vision, tinnitus, and vomiting, are not typically associated with an acute allergic reaction to Penicillin.

Correct Answer: A

Rationale: The basis for pharmacotherapeutics lies in the selective action of drugs with regard to the diagnosis, prevention, and treatment of diseases. Pharmacotherapeutics involves the use of drugs to manage diseases and improve health outcomes. Drugs are carefully selected based on their mechanism of action, efficacy, safety profile, and suitability for a specific condition. The goal is to achieve optimal therapeutic effects while minimizing potential adverse effects. By understanding the selective action of drugs in targeting specific pathways or processes in the body, healthcare providers can customize treatment regimens to individual patients and achieve the best possible outcomes.

Correct Answer: A

Rationale: A decoction is a liquid preparation made by boiling vegetable substances with water. This process helps extract the beneficial properties and compounds from the plant material into the liquid. Decoctions are commonly used in herbal medicine to prepare medicinal remedies by simmering roots, bark, or other plant parts in water for a period of time.

Correct Answer: A

Rationale: Myelosuppression, a common side effect of chemotherapy, leads to a decrease in white blood cells, red blood cells, and platelets. A drop in white blood cells, particularly neutrophils, increases the risk of infection. Monitoring for a change in temperature is critical because fever is often the first sign of infection in neutropenic patients. Early detection allows for prompt intervention, such as administering antibiotics, to prevent life-threatening complications. While gastrointestinal function, cardiac compromise, and changes in taste are important to assess, they are not as immediately life-threatening as an undetected infection in a myelosuppressed patient.
