A young client with cystic fibrosis (CF) is on dornase alfa. What does the nurse teach about the action of this medication?

Relieves nasal congestion

Decreases thick secretions

Decreases pain

Suppresses cough

Answer and Explanation

The Correct Answer is B

A. Relieves nasal congestion

Dornase alfa is not used to relieve nasal congestion. It is specifically designed to address the thick, sticky mucus that can accumulate in the airways of individuals with cystic fibrosis (CF).

B. Decreases thick secretions

This is the correct answer. Dornase alfa is known for its ability to decrease the viscosity of thick secretions in the airways of individuals with CF. By breaking down the DNA within the mucus, it helps to thin and improve the clearance of the mucus.

C. Decreases pain

Dornase alfa is not primarily used to decrease pain. Its main action is related to improving respiratory function by reducing the thickness of mucus, which can help ease breathing difficulties associated with CF.

D. Suppresses cough

Dornase alfa is not used to suppress cough. In fact, it may increase coughing initially as it facilitates the loosening and clearance of mucus from the airways.

Correct Answer is C

Explanation

Explanation:

A. Administer phenergan (Promethazine) 12.5 mg IVP at the first complaint of nausea.

This option suggests waiting until the patient complains of nausea before administering the antiemetic. It is not a proactive approach and may not effectively prevent nausea associated with chemotherapy.

B. Administer ondansetron (Zofran) 4mg IV Push after Ms. Samuels complains of nausea.

Similar to option A, this choice involves waiting for the patient to experience nausea before administering the medication. Again, it is not a proactive strategy for preventing chemotherapy-induced nausea and vomiting.

C. Administer ondansetron (Zofran) 4mg IV push sometime between 1300-1330.

This option is the most appropriate among the given choices. It suggests administering the antiemetic (ondansetron) before the scheduled chemotherapy session. Ondansetron is commonly used as a prophylactic measure to prevent nausea and vomiting associated with chemotherapy.

D. Administer phenergan (Promethazine) 25 mg PO at 1345.

This choice involves administering the antiemetic (phenergan) orally just 15 minutes before the scheduled chemotherapy session. While it is better than waiting for symptoms to appear, oral medications may take some time to be absorbed, and it might not provide as rapid relief as an intravenous (IV) medication.

A. because many chemotherapy patients require blood transfusions B. because many chemotherapy patients need long-term intravenous access C. because chemotherapy patients have frequent blood draws orders D. because many chemotherapeutic drugs are vesicants

Correct Answer is D

Explanation

. 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).
