A client who will be undergoing chemotherapy and internal radiation for cancer treatment asks the nurse why they are scheduled for the placement of a central venous access device (CVAD). Which of the following is a benefit of placing a CVAD for someone who will be undergoing cancer treatment?

Allows for long-term administration of chemotherapy

Can be used to implant radioactive material for internal radiation treatments

Eliminates the risk of infection associated with accessing a blood vessel

Reduces the risk of nausea and vomiting caused by chemotherapy medication

Answer and Explanation

The Correct Answer is A

A.   Chemotherapy often requires multiple infusions over a long period, and a CVAD provides a reliable and convenient access point for these treatments. It allows for the continuous or intermittent administration of chemotherapy drugs, which are often irritating to veins and require precise dosing.
B.   While CVADs are used for administering chemotherapy and other treatments, they are not typically used to implant radioactive material for internal radiation (brachytherapy).
C.   While CVADs reduce the need for repeated venipunctures and can help manage the complications of frequent injections, they do not eliminate the risk of infection. CVADs can themselves become a source of infection if not properly maintained, as they are open to the external environment.
D.   The placement of a CVAD does not directly affect the side effects of chemotherapy, such as nausea and vomiting. The CVAD’s role is primarily related to the administration of medications and access to blood vessels.

Correct Answer is A

Explanation

A. Pursed-lip breathing is an effective technique for managing COPD symptoms, particularly tachypnea and dyspnea. It helps to keep the airways open by creating back pressure that prevents the collapse of bronchioles and reduces air-trapping. This technique improves ventilation and helps with the expiration of trapped air, making it a valuable intervention for COPD patients.
B. The Trendelenburg position involves lying flat on the back with the legs elevated higher than the head. This position is not suitable for managing COPD symptoms and can actually worsen breathing difficulties by increasing abdominal pressure on the diaphragm.
C. High-frequency chest wall oscillation (HFCWO) vests are used to help with airway clearance in conditions like cystic fibrosis or chronic bronchitis by loosening mucus. While beneficial for mucus management, they do not specifically address bronchiolar collapse or air-trapping associated with COPD.
D. Measuring the FEV1/FVC ratio is a diagnostic tool used to assess the severity of airflow obstruction in COPD. While this information is important for diagnosis and treatment planning, it is not an immediate intervention to manage symptoms such as tachypnea and dyspnea.

A. The procedure uses electrical energy to destroy areas of the conduction system. B. The procedure uses cold therapy to stop the formation of the flutter waves. C. The procedure removes clots which have formed in the atria. D. The procedure stimulates the growth of new conduction pathways between the atria.

Correct Answer is A

Explanation

A. Radiofrequency catheter ablation involves the use of electrical energy (radiofrequency energy) delivered through a catheter to destroy or ablate the areas of the heart tissue responsible for the abnormal electrical signals causing atrial flutter. This destruction of tissue helps to interrupt the abnormal electrical pathways and restore normal rhythm.
B. The procedure for atrial flutter ablation does not use cold therapy. Instead, it uses radiofrequency energy (heat) to ablate the tissue. Cold therapy, or cryoablation, is a different technique that uses extreme cold to achieve similar effects but is not the standard approach for radiofrequency catheter ablation.
C. Radiofrequency catheter ablation does not involve removing clots. The primary purpose of the procedure is to ablate abnormal tissue causing arrhythmias, not to address clots. Managing clots may involve anticoagulant therapy or other treatments, but it is not the focus of ablation.
D. Radiofrequency catheter ablation does not stimulate the growth of new conduction pathways. Instead, it aims to destroy the abnormal conduction pathways responsible for arrhythmias.
