The nurse receives an order to draw a peak level on a patient prescribed Gentamicin via Intravenous (IV) infusion. When is the best time for the nurse to draw this peak level?

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.

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.
