A nurse is caring for a client who has a new diagnosis of atrial fibrillation. Despite medication therapy aimed at correcting the dysrhythmia, the patient has consistently remained in atrial fibrillation for several days. Which of the following interventions would the nurse expect to be ordered for this client?
Emergency defibrillation
Coronary artery bypass graft (CABG)
Anticoagulant therapy
Diuretic therapy
The Correct Answer is C
A. Defibrillation is not typically indicated for atrial fibrillation. Atrial fibrillation involves disorganized electrical activity in the atria rather than a shockable rhythm like ventricular fibrillation or ventricular tachycardia. Therefore, emergency defibrillation is not appropriate for a client with persistent atrial fibrillation.
B. CABG is a surgical procedure used to improve blood flow to the heart muscle by bypassing blocked coronary arteries. It is primarily indicated for clients with significant coronary artery disease that cannot be managed effectively with medications or less invasive
C. Anticoagulant therapy, such as with medications like warfarin or direct oral anticoagulants (DOACs), is crucial for clients with atrial fibrillation. AFib predisposes individuals to an increased risk of stroke due to the potential formation of blood clots in the atria. Anticoagulants help prevent clot formation and reduce the risk of stroke.
D. Diuretics are medications that increase urine output and are often used to manage fluid overload or congestion in conditions such as heart failure or volume overload. However, diuretic therapy alone does not address the underlying rhythm abnormality of atrial fibrillation.

Correct Answer is ["1.5"]
Explanation
To administer the correct dose of desipramine, which is 150 mg, when the available tablet strength is 100 mg, the nurse would need to give 1.5 tablets.
Correct Answer is C
Explanation
A. During chemotherapy, many patients experience nausea, vomiting, and changes in taste or appetite. Spicy and highly-seasoned foods can exacerbate gastrointestinal symptoms and may not be well tolerated. It's generally recommended to encourage bland, easy-to-digest foods to help maintain adequate nutrition and reduce discomfort.
B. Loperamide is not used to prevent nausea; rather, it is an antidiarrheal medication used to treat diarrhea, which can be a side effect of chemotherapy. Nausea prevention is typically managed with antiemetic medications such as ondansetron, metoclopramide, or others prescribed based on the patient's specific needs and chemotherapy regimen.
C. Pain management is an essential aspect of caring for oncology patients, including those receiving chemotherapy. Cancer and its treatment can cause pain directly or indirectly (such as from procedures or complications). Regular and thorough pain assessments allow for timely intervention and improvement in the client's comfort and quality of life.
D. Chemotherapy medications are typically administered through central venous access devices (e.g., central lines, PICC lines) rather than through peripheral veins. This is because chemotherapy drugs can be vesicants (causing tissue damage if they leak out of the vein) or irritants to smaller peripheral veins.
Using a larger gauge peripheral line (e.g., 18 gauge) is not standard practice for administering chemotherapy due to the potential risks and complications associated with peripheral administration.
