Correct Answer is B
Explanation
A. A negative waveform indicates a downward deflection from the baseline on an ECG tracing, which may correspond to electrical activity such as depolarization or repolarization of cardiac chambers.
B. An isoelectric line represents the baseline on an ECG tracing when there is no net electrical activity occurring in the heart. It appears flat and represents a period of electrical silence.
C. A downward deflection on an ECG tracing refers to a negative waveform, as mentioned above.
D. A positive waveform on an ECG tracing indicates an upward deflection from the baseline, representing electrical activity such as depolarization or repolarization.
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.
