A patient with a new diagnosis of lung cancer decides to have radiation therapy. Which of the ff. expectations of this treatment is most appropriate?

Correct Answer: C

Rationale: Radiation therapy for lung cancer is typically used with the goal of increasing comfort for the patient by reducing symptoms such as pain, shortness of breath, and coughing. While it may help to shrink tumors and slow the progression of the disease, it is usually not considered a curative treatment for advanced lung cancer. It is important for the patient to have realistic expectations and understand that the goal of radiation therapy is primarily to improve their quality of life and manage symptoms.

Correct Answer: B

Rationale: Chorea is the result of central nervous system manifestations. Chorea is a movement disorder characterized by involuntary, brief, random, and irregular muscle movements that are often seen in neurological conditions such as Huntington's disease. The central nervous system is responsible for controlling and coordinating movements, so any dysfunction in the central nervous system can lead to movement disorders like chorea. Therefore, chorea is directly related to central nervous system manifestations, unlike congestive heart failure, valve damage, or pericarditis which are primarily related to cardiovascular issues.

Correct Answer: D

Rationale: In the scenario of a patient developing an anaphylactic reaction to penicillin via IV piggyback, the nurse's first action should be to discontinue the administration of the antibiotic to prevent further exposure and potential worsening of the reaction. Turning off the antibiotic is critical as it stops the source of the allergic reaction. This step takes precedence over any other actions including calling the doctor, maintaining the antibiotic, or calling for help, as stopping the infusion is the most immediate and important action to take in managing an anaphylactic reaction. Once the antibiotic has been turned off, the nurse can then proceed with providing appropriate emergency treatments and notifying the healthcare team for further management.

Correct Answer: C

Rationale: Antihistamines are medications commonly used to relieve symptoms of allergies, including itching, sneezing, and hives. When a client undergoing a diagnostic skin test for allergies takes antihistamines, it can suppress the body's allergic response, leading to false negative results. This means that the test may not accurately identify all the substances to which the client is allergic, potentially leading to a misdiagnosis. To ensure the accuracy of the skin test, clients are advised to avoid taking antihistamines or cold preparations for at least 48-72 hours before the testing to allow their body to exhibit the appropriate allergic response.

Correct Answer: A

Rationale: The nurse should instruct the client to comply with the timing of antiviral medication around meals. Taking some antiviral medications with food can help reduce gastrointestinal side effects. Certain medications may be more effective when taken with food, while others may need to be taken on an empty stomach. It is essential for the client to follow the specific instructions given by their healthcare provider to ensure the optimal effectiveness of the antiviral medications.
