Why does a nurse on an oncology unit verify a client's current cumulative lifetime dose of doxorubicin before administering it to a client with breast cancer?

Correct Answer: C

Rationale: Verifying the client's current cumulative lifetime dose of doxorubicin is necessary because excessive amounts of the medication can lead to cardiomyopathy, a serious and potentially life-threatening side effect. By monitoring the cumulative dose, healthcare providers can help prevent cardiotoxicity and ensure patient safety during treatment.

Correct Answer: B

Rationale: Montelukast is typically taken once daily in the evening for long-term control of asthma symptoms. It helps prevent asthma attacks by reducing inflammation in the airways. While montelukast can also be used for exercise-induced bronchospasm in some cases, it is generally not a rescue medication and should be taken regularly, not on an as-needed basis.

Correct Answer: D

Rationale: After a pneumonectomy, positioning the client in a semi-Fowler's position is crucial for optimal ventilation. This position helps improve lung expansion on the remaining side, facilitating better oxygenation and preventing complications like atelectasis. Placing the client prone, on the nonoperative side, or in Sims' position would not provide the same respiratory benefits post-pneumonectomy.
