Which of the following arrhythmias is associated with heart failure?

First-degree heart block

Atrial fibrillation

Ventricular tachycardia

Sinus bradycardia

Answer and Explanation

Correct Answer : B,C

Choice A Reason:
First-degree heart block is a condition where the electrical signals in the heart are delayed but still reach the ventricles. It is generally considered benign and does not typically lead to heart failure. It is often asymptomatic and discovered incidentally on an ECG.

Choice B Reason:
Atrial fibrillation (AFib) is a common arrhythmia associated with heart failure. AFib causes the atria to beat irregularly and often rapidly, which can lead to poor blood flow and increased risk of stroke. In heart failure patients, AFib can exacerbate symptoms and worsen the prognosis due to the loss of atrial contraction and irregular ventricular response.

Choice C Reason:
Ventricular tachycardia (VT) is a serious arrhythmia that is often associated with heart failure. VT originates in the ventricles and can lead to hemodynamic instability and sudden cardiac death if not treated promptly. It is a common complication in patients with heart failure and cardiomyopathy.

Choice D Reason:
Sinus bradycardia is a slower than normal heart rate, typically less than 60 beats per minute. While it can occur in healthy individuals, especially athletes, it is not specifically associated with heart failure. In some cases, severe bradycardia can lead to symptoms of heart failure, but it is not a primary arrhythmia linked to the condition.

Correct Answer is ["7.2"]

Explanation

Step-by-Step Calculation:

Step 1: Convert the client's weight from pounds to kilograms.

176 lbs ÷ 2.2 = 80 kg

Result = 80 kg

Step 2: Calculate the total dose of dopamine in mcg/min.

3 mcg/kg/min × 80 kg = 240 mcg/min

Result = 240 mcg/min

Step 3: Convert the total dose from mcg/min to mg/min.

240 mcg/min ÷ 1000 = 0.24 mg/min

Result = 0.24 mg/min

Step 4: Determine the concentration of dopamine in mg/mL.

500 mg ÷ 250 mL = 2 mg/mL

Result = 2 mg/mL

Step 5: Calculate the infusion rate in mL/min.

0.24 mg/min ÷ 2 mg/mL = 0.12 mL/min

Result = 0.12 mL/min

Step 6: Convert the infusion rate to mL/hr.

0.12 mL/min × 60 min/hr = 7.2 mL/hr

Result = 7.2 mL/hr

Final Result:

The IV pump should be set to 7.2 mL/hr.

A. Urine output B. Heart rate C. Blood pressure D. Mental status E. Capillary refill

Correct Answer is A

Explanation

Choice A Reason:
Urine output is one of the most reliable indicators of adequate fluid resuscitation in burn patients. The goal is to maintain a urine output of 0.5 to 1 mL/kg/hour in adults³. This parameter is crucial because it directly reflects renal perfusion and, by extension, overall circulatory volume status. When fluid resuscitation is adequate, the kidneys receive enough blood flow to produce urine at this rate, indicating that the body's tissues are being adequately perfused. Monitoring urine output is a non-invasive and straightforward method, making it a preferred choice in clinical settings.

Choice B Reason:
Heart rate can be an indicator of fluid status, but it is less reliable than urine output. Tachycardia (an increased heart rate) can occur due to pain, anxiety, or other stressors, not just fluid deficit. While a decreasing heart rate might suggest improving fluid status, it is not a definitive indicator on its own. Other factors must be considered in conjunction with heart rate to assess fluid resuscitation adequacy.

Choice C Reason:
Blood pressure is another parameter used to assess fluid status, but it can be influenced by many factors, including the patient's baseline blood pressure, medications, and the presence of other medical conditions. While maintaining adequate blood pressure is important, it is not as sensitive or specific as urine output for assessing fluid resuscitation in burn patients. Blood pressure can remain within normal ranges even when fluid resuscitation is inadequate, especially in the early stages.

Choice D Reason:
Mental status can be affected by fluid status, but it is a late indicator of inadequate perfusion. Changes in mental status, such as confusion or decreased level of consciousness, can occur when there is significant hypoperfusion and shock. By the time mental status changes are observed, the patient may already be in a critical state. Therefore, it is not a primary indicator for assessing fluid resuscitation adequacy.

Choice E Reason:
Capillary refill time is a quick and simple test to assess peripheral perfusion. However, it is not as reliable as urine output for evaluating overall fluid status. Capillary refill can be affected by ambient temperature, lighting conditions, and the examiner's technique. While a prolonged capillary refill time can indicate poor perfusion, it is not as specific or sensitive as urine output for assessing fluid resuscitation adequacy.
