The nurse is caring for a patient whose cardiac monitor shows a total absence of electrical impulse as indicated by a flat line. The nurse does not detect a pulse or blood pressure. The nurse would document this as which of the following rhythms?
Atrial fibrillation
Asystole
Ventricular fibrillation
Atrial flutter
The Correct Answer is B
A. Atrial fibrillation is characterized by rapid, irregular electrical impulses originating from the atria, resulting in a quivering or fibrillating motion of the atria rather than a coordinated contraction.
B. Asystole is the absence of any electrical activity on the cardiac monitor, resulting in a flat line. It indicates the absence of ventricular contraction and is considered a medical emergency requiring immediate intervention (CPR and advanced cardiac life support).
C. Ventricular fibrillation is characterized by chaotic, disorganized electrical activity in the ventricles, resulting in ineffective quivering of the ventricles and loss of cardiac output.
D. Atrial flutter is characterized by rapid but regular electrical impulses originating from the atria, resulting in a sawtooth pattern on the ECG tracing.

Correct Answer is B
Explanation
A. Showering is not typically restricted after a splenectomy. Good hygiene practices, including regular showering, are important for preventing infection.
B. Patients who have undergone a splenectomy are at increased risk of infections, particularly from encapsulated bacteria such as Streptococcus pneumoniae. Yearly flu vaccination helps reduce the risk of influenza-related complications.
C. Long-term antibiotic prophylaxis is not routinely recommended for all patients after splenectomy. Antibiotics may be prescribed in certain situations, such as for postsplenectomy sepsis prevention, but lifelong use is not standard practice.
D. Sleeping position is not directly related to infection prevention after splenectomy.
General infection prevention measures, such as vaccination and avoiding exposure to sick individuals, are more important.
Correct Answer is B
Explanation
A. While bone involvement can occur in Hodgkin lymphoma, it is not typically associated with a high risk of spontaneous pathological fractures compared to multiple myeloma.
B. Multiple myeloma is characterized by the destruction of bone tissue, leading to an increased risk of spontaneous pathological fractures.
C. Leukemia primarily affects the bone marrow and may cause bone pain but does not typically lead to spontaneous pathological fractures.
D. Hemophilia is a bleeding disorder characterized by a deficiency in clotting factors and is not directly associated with an increased risk of spontaneous pathological fractures.
