What is seen on an ECG tracing when there is no electrical activity being produced?

Negative waveform

Isoelectric line

Downward deflection

Positive waveform

Answer and Explanation

The Correct Answer is B

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.

Explanation

A. Coffee is generally well tolerated unless the patient experiences discomfort or adverse effects from caffeine. It does not typically pose specific risks for patients with Hodgkin's disease.
B. Orange juice is generally safe to consume unless the patient has specific dietary restrictions or intolerances. It provides vitamin C and hydration.
C. Ginger ale is a non-caffeinated, carbonated beverage that is often used to alleviate nausea and upset stomach. It is generally safe to consume for patients with Hodgkin's disease unless there are individual sensitivities.
D. Alcohol consumption, including wine, should be avoided by patients with Hodgkin's disease, especially during treatment. Alcohol can suppress the immune system and may interact with medications or exacerbate side effects.

A. auscultate the right brachial pulse B. palpate for thrill over the right arm fistula C. measure the blood pressure in the right arm D. auscultate the right radial pulse E. auscultate bruit over the right arm fistula F. palpate the right radial pulse

Correct Answer is ["B","E"]

Explanation

A. Auscultating the brachial pulse is not typically used to assess the patency of an arteriovenous fistula.
B. A thrill is a vibration felt over an arteriovenous fistula or graft and indicates proper blood flow. Palpation for thrill is a standard method to assess fistula patency.
C. Blood pressure measurement does not directly assess the patency of an arteriovenous fistula.
D. Auscultating the radial pulse is not typically used to assess the patency of an arteriovenous fistula.
E. A bruit is a swooshing sound heard over an arteriovenous fistula or graft and indicates turbulent blood flow. Auscultating for bruit is another method to assess fistula patency.
F. Palpate the right radial pulse: Palpating the radial pulse is not typically used to assess the patency of an arteriovenous fistula.
