The oncology RN knows that the most important reason that patients who are undergoing chemotherapy have either intravenous ports, central lines, or peripherally inserted central line is:
because many chemotherapy patients require blood transfusions
because many chemotherapy patients need long-term intravenous access
because chemotherapy patients have frequent blood draws orders
because many chemotherapeutic drugs are vesicants
The Correct Answer is D
. because many chemotherapy patients require blood transfusions:
While some chemotherapy patients may require blood transfusions, this is not the primary reason for using intravenous ports, central lines, or peripherally inserted central lines.
B. because many chemotherapy patients need long-term intravenous access:
Long-term intravenous access may be needed for some chemotherapy patients, but the critical consideration is the vesicant nature of many chemotherapy drugs.
C. because chemotherapy patients have frequent blood draws orders:
Frequent blood draws may be necessary for monitoring purposes, but the primary reason for using specialized lines in chemotherapy patients is to administer the drugs safely.
D. because many chemotherapeutic drugs are vesicants:
The primary reason for using intravenous ports, central lines, or peripherally inserted central lines in chemotherapy patients is to administer chemotherapy drugs directly into large veins. Many chemotherapeutic drugs are vesicants, meaning they can cause severe damage to tissues if they leak into the surrounding areas. These specialized lines allow for the safe and controlled administration of chemotherapy drugs, reducing the risk of extravasation (leakage into surrounding tissues).

Correct Answer is A
Explanation
. Decreased coughing:
Dextromethorphan is primarily used as an antitussive, meaning it helps reduce coughing. It acts on the cough center in the brain to suppress the urge to cough.
B. Relief of nasal congestion:
Dextromethorphan is not typically used for relieving nasal congestion. Decongestants, such as pseudoephedrine, are more commonly used for this purpose.
C. Thinning of secretions:
Dextromethorphan does not have a direct effect on thinning secretions. Expectorants, like guaifenesin, are often used for this purpose.
D. Bronchodilation:
Dextromethorphan is not known for its bronchodilator effects. Bronchodilators, such as albuterol, are used for widening the airways in conditions like asthma or chronic obstructive pulmonary disease (COPD).
Correct Answer is A
Explanation
A. To help prevent Tumor Lysis Syndrome.
Encouraging fluid intake is crucial for patients undergoing chemotherapy, especially when there's a risk of Tumor Lysis Syndrome (TLS). TLS is a potentially serious complication that can occur when cancer cells release their contents into the bloodstream, leading to metabolic imbalances. Adequate hydration helps prevent the concentration of these released substances and reduces the risk of TLS.
B. Staying hydrated decreases oral dryness that the patient may exhibit as a result of chemotherapy.
While hydration is generally important for overall well-being, oral dryness is not typically a direct consequence of bladder cancer chemotherapy. It might be a side effect of certain medications, but the primary concern in this case is likely related to preventing TLS.
C. To help prevent new onset diabetes mellitus.
The rationale for fluid intake in the context of bladder cancer chemotherapy is not typically related to preventing new onset diabetes mellitus. The primary focus is usually on managing potential side effects of chemotherapy and promoting overall health.
D. Because it is better to encourage water Vs. carbonated beverages.
While encouraging water over carbonated beverages is generally a healthy choice, the primary rationale for increased fluid intake in the context of bladder cancer chemotherapy is more specific and related to preventing Tumor Lysis Syndrome.
