Question

Which of the following describes the correct use of a Transcutaneous electrical nerve stimulation (TENS) unit?

a) The unit should be turned on when repositioning or removing electrodes.
b) For acute pain, a recommended pulse of 30 to 50 microseconds should be used.
c) TENS should not be used when the etiology of the pain is unknown.
d) The electrodes should be placed over the carotid sinus nerves or over pharyngeal muscles.

Answer 1

The correct use of a TENS unit includes not using it when the cause of the pain is unknown and avoiding placing electrodes over sensitive areas like the carotid sinus nerves.

Step-by-step explanation:

The correct use of a Transcutaneous electrical nerve stimulation (TENS) unit is described by not using it when the etiology of the pain is unknown. Turning on the unit while repositioning or removing electrodes can cause unnecessary stimulation or discomfort. Using a pulse of 30 to 50 microseconds is a typical setting for acute pain management. However, electrodes should never be placed over the carotid sinus nerves or pharyngeal muscles as this can be dangerous.

The correct use of a Transcutaneous electrical nerve stimulation (TENS) unit is to turn it on after positioning or attaching the electrodes. This ensures that the unit is not activated accidentally during the process. For acute pain, a recommended pulse of 30 to 50 microseconds should be used. TENS can be used even when the etiology of the pain is unknown, as it can help alleviate pain and promote healing. The electrodes should not be placed over the carotid sinus nerves or pharyngeal muscles, as these areas can be sensitive and may cause unwanted effects.

Answer 2

The following describes the correct use of a Transcutaneous electrical nerve stimulation (TENS) unit is a) The unit should be turned on when repositioning or removing electrodes.

Step-by-step explanation:

This ensures that the unit is not accidentally activated during electrode adjustment. For acute pain, a recommended pulse duration of 30 to 50 microseconds should be used. This pulse duration helps to effectively stimulate the nerves and relieve pain.

TENS can be used when the etiology of the pain is unknown. It is a non-invasive and safe method of pain management that can provide relief for various types of pain. When using a TENS unit, the electrodes should never be placed over the carotid sinus nerves or over pharyngeal muscles. These locations can cause unwanted stimulation and potential harm. Therefore the correct answer is a) The unit should be turned on when repositioning or removing electrodes.
