A 58-year-old man is going to have chemotherapy for lung cancer. He asks the nurse how the chemotherapeutic drugs will work.The most accurate explanation the nurse can give is which of the following?
"The molecular structure of the DNA is altered."
"Cancer cells are susceptible to drug toxins."
"Chemotherapy encourages cancer cells to divide."
"Chemotherapy affects all rapidly dividing cells."
The Correct Answer is D
Chemotherapy is a treatment modality used to target and destroy rapidly dividing cells, including cancer cells. It works by interfering with the cell division process, which is a characteristic of cancer cells. However, it is important to note that chemotherapy drugs can also affect normal, healthy cells in the body that undergo rapid division, such as cells in the bone marrow, hair follicles, and gastrointestinal lining. This is why chemotherapy can be associated with side effects like bone marrow suppression, hair loss, and gastrointestinal disturbances. While the molecular structure of DNA can be altered by certain chemotherapeutic drugs, this explanation is not comprehensive enough to encompass the overall mechanism of action of chemotherapy.
The statement that "cancer cells are susceptible to drug toxins" is partially true, as cancer cells are generally more vulnerable to the cytotoxic effects of chemotherapy drugs compared to normal cells.
Chemotherapy aims to disrupt the division and growth of cancer cells rather than promoting their division.

Correct Answer is B
Explanation
Pain tolerance refers to the maximum level of pain that an individual can tolerate without significant distress. It is influenced by various factors, including psychological and emotional factors. While emotions such as anger, boredom, and introversion can have an impact on a person's pain perception and experience, sleep plays a significant role in pain tolerance. During sleep, the body is in a state of rest and relaxation, allowing for decreased sensory input and potentially reducing pain perception. Sleep provides an opportunity for the body to repair and heal, which can contribute to improved pain tolerance. Additionally, sleep promotes the release of endogenous opioids, which are natural pain-relieving substances produced by the body.
Correct Answer is B
Explanation
After rhinoplasty, nasal packing is often used to control bleeding and provide support to the nasal structures. Nasal packing can cause oral dryness, as it obstructs the normal airflow through the nasal passages, leading to mouth breathing. Mouth breathing, in turn, can cause dryness of the oral mucosa and throat, resulting in the sensation of dryness and the need to swallow frequently.
While bleeding is a possible complication after rhinoplasty, the patient's symptom of frequent swallowing is more indicative of oral dryness rather than bleeding.
Although adverse reactions to analgesics can occur, frequent swallowing is not a common symptom associated with analgesic adverse reactions. Other signs such as rash, difficulty breathing, or changes in vital signs would be more typical in case of an adverse reaction. Swallowing can be a normal response to surgery, but in this scenario, the most likely cause is the oral dryness caused by the nasal packing rather than a direct response to the analgesic.
