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.

Explanation
Low oxygen saturation: Low oxygen saturation indicates a potential respiratory compromise and should be addressed promptly to ensure adequate oxygenation and prevent further deterioration.
Previous injection drug user and alcohol misuse: Past injection drug use and alcohol misuse can have significant implications for the patient's health, including increased risk of infections, compromised immune function, and potential withdrawal symptoms. It is crucial for the nurse to be aware of these factors in order to provide appropriate care and support. Has productive cough severe enough to keep her awake: A severe productive cough that disrupts the patient's sleep suggests respiratory distress or possible worsening of the underlying condition. The nurse should assess the patient's respiratory status and implement interventions to alleviate the cough and improve rest.
Elevated temperature, pulse, and respiratory rate: An elevation in vital signs, including temperature, pulse, and respiratory rate, can indicate an infectious or inflammatory process. This warrants further assessment and intervention to manage the underlying condition. Diagnosis pneumonia: The diagnosis of pneumonia indicates a respiratory infection that requires close monitoring and appropriate treatment. The nurse should assess the patient's respiratory status, administer prescribed medications, and implement respiratory hygiene measures.
The following options are not immediate concerns or relevant assessment information:
Appointment the next day: While follow-up appointments are important, they do not require immediate attention upon receiving a hand-off report.
Marital status: Marital status is not typically an immediate concern for the nurse's assessment and care planning.
Daughter's name: The patient's family member's name is not an immediate concern or relevant assessment information for the nurse's immediate care.
Fever is present: While a fever is a symptom of an underlying condition, it is not the most critical concern.

Explanation
● Weight 98 lbs: This information helps determine the patient's baseline weight and assess for potential weight loss associated with dehydration.
● Dehydrated: The diagnosis of dehydration indicates a critical condition that requires immediate attention and intervention.
● Lethargy: Lethargy suggests a decreased level of consciousness and could indicate a severe state of dehydration or other underlying issues that need to be addressed promptly.
● HR 122: A heart rate of 122 beats per minute is elevated and may indicate compensatory mechanisms in response to dehydration or other underlying conditions. It requires further evaluation and intervention.
● Shortness of Breath: This symptom suggests respiratory distress and may be related to the patient's dehydration or underlying conditions. It requires immediate assessment and intervention.
● Temperature 100: An elevated temperature may indicate an underlying infection or inflammatory response. It requires further evaluation to determine the cause and guide appropriate treatment.
● Thirsty: The patient's report of feeling thirsty is an important symptom indicating dehydration and the need for fluid replacement.
● BP 90/50: A blood pressure of 90/50 is low and may be indicative of hypotension, which can occur in dehydration. It requires close monitoring and intervention to stabilize the patient's blood pressure.
The following items are not immediate concerns based on the given information: ● Admitted to the ER: While it is important information, it is not a current concern as the patient is already in the ER.
● Female: The patient's gender is not an immediate concern for the assessment and management of dehydration.
