The nurse is caring for a patient who has had three or more premature ventricular contractions occurring in a row on the electrocardiogram tracing. The nurse should document this as which of the following?
Ventricular tachycardia
Bigeminy
Ventricular fibrillation
Trigeminy
The Correct Answer is A
A. Three or more consecutive premature ventricular contractions (PVCs) on an ECG tracing is indicative of ventricular tachycardia, a serious arrhythmia that requires prompt intervention.
B. Bigeminy refers to a pattern of every other beat being a PVC, not necessarily three or more consecutive PVCs.
C. Ventricular fibrillation is characterized by chaotic, disorganized ventricular activity on the ECG and is not defined by the presence of consecutive PVCs.
D. Trigeminy refers to a pattern of every third beat being a PVC, not necessarily three or more consecutive PVCs.

Explanation
First, Hodgkin lymphoma (HL) is commonly characterized by painless lymphadenopathy and is not painful, as stated above. Secondly, HL is often characterized by a low-grade fever rather than a high fever. Third, the presence of Bence-Jones cells in a laboratory test is not associated with Hodgkin lymphoma but indicates multiple myeloma, a different type of cancer. Fourth, Hodgkin disease is indeed a form of cancer; it is a malignancy of the lymphatic system. The nurse's statement that it is "not really cancer" is incorrect and misleading. Fifth, palliative radiation therapy is typically used to relieve symptoms in advanced stages of cancer or non-curative scenarios. However, for stage 1 Hodgkin lymphoma, the treatment usually involves chemotherapy and/or radiation therapy with curative intent, not palliative. Joe's nurse should provide accurate information about the nature of Hodgkin's disease and its treatment options, which are based on the stage and specific characteristics of the lymphoma.
Correct Answer is {"dropdown-group-1":"A","dropdown-group-2":"B"}
Explanation
Bleeding: The client's platelet count has dropped from 160,000/mm³ to 100,000/mm³, which is below the normal range (150,000 to 400,000/mm³). Platelets are essential for blood clotting, and a low count increases the risk of bleeding. Additionally, the prolonged PT (13.5 seconds) and elevated INR (2.2) further indicate a tendency toward bleeding.
Infection: The client's WBC count remains elevated at 15,500/mm³, which can be indicative of ongoing infection or inflammation. Patients with acute leukemia often have dysfunctional white blood cells, which impairs their ability to fight infections effectively.
