Question

Which of the following findings is consistent with bradycardia? a. Hyperventilation b. Blood pressure of 100/80 mm Hg c. Cold and clammy skin d. Pulse rate of 140/min

Answer 1

The finding consistent with bradycardia, which is a slower than normal heart rate (below 60 bpm), is cold and clammy skin. This may indicate the heart is not supplying enough oxygenated blood. A pulse rate of 140/min would indicate tachycardia, not bradycardia.

Step-by-step explanation:

The question asks which finding is consistent with bradycardia, which is a condition where the resting heart rate is below 60 beats per minute (bpm). The correct answer is pulse rate of 140/min is not consistent with bradycardia; therefore, it is not the right finding. Instead, findings such as cold and clammy skin can be associated with bradycardia because they may indicate that the heart is not providing sufficient oxygenated blood to the tissues. Other factors such as hyperventilation, blood pressure of 100/80 mm Hg, and pulse rate of 140/min are not consistent with bradycardia. Resting heart rates significantly lower than normal can lead to symptoms such as weakness, fatigue, dizziness, and others. Bradycardia may be caused by various internal and external factors, and treatment depends on identifying the underlying cause.

Answer 2

Options a, b, and c are more consistent with bradycardia:

Bradycardia is a condition characterized by a slower than normal heart rate. The normal adult heart rate is typically between 60 and 100 beats per minute. Therefore, a pulse rate of 140/min (option d) is inconsistent with bradycardia. Instead, it suggests tachycardia, which is an abnormally high heart rate.

Options a, b, and c are more consistent with bradycardia:

a. Hyperventilation:*This is not typically associated with bradycardia. Bradycardia is more commonly associated with a decreased respiratory rate.

b. Blood pressure of 100/80 mm Hg: This finding is consistent with bradycardia. In bradycardia, the heart pumps blood at a slower rate, and it may lead to lower blood pressure.

c. Cold and clammy skin: This finding is consistent with bradycardia. In bradycardia, reduced cardiac output can lead to poor peripheral circulation and cold, clammy skin.

So, among the given options, a pulse rate of 140/min (option d) is not consistent with bradycardia. Options b and c are more in line with findings that may be associated with bradycardia.
