A patient is beginning treatment for pain with a transcutaneous electrical nerve stimulator (TENS) unit.
The nurse will initially:.

place electrodes on all four extremities.

adjust the settings below the level at which a tingling sensation is felt.

turn the unit on before attaching it to the patient.

apply conductive jelly to uncoated electrodes.

Answer and Explanation

The Correct Answer is B

Choice A rationale:

Placing electrodes on all four extremities is not the initial step in using a Transcutaneous Electrical Nerve Stimulator (TENS) unit. It may not be necessary for the specific pain management needs of the patient and can be uncomfortable or impractical.

Choice B rationale:

This is the correct initial step when starting TENS treatment. The nurse should adjust the settings to a level below the threshold at which the patient feels a tingling sensation. This ensures that the treatment is comfortable and safe for the patient. The goal is to provide pain relief, not to induce discomfort.

Choice C rationale:

Turning the unit on before attaching it to the patient is not advisable. It's essential to connect the electrodes to the patient first and then turn on the TENS unit. This sequence helps prevent accidental electrical stimulation before the device is properly set up.

Choice D rationale:

Applying conductive jelly to uncoated electrodes is a step in preparing the electrodes for use, but it should be done after attaching the electrodes to the patient's skin. This choice does not address the initial step in TENS treatment, which is setting the stimulation level. .

Correct Answer is D

Explanation

Choice A rationale:
The CPAP device should not fit loosely on the face. It should fit snugly to create a proper seal and maintain positive airway pressure. A loose-fitting CPAP mask may not effectively treat obstructive sleep apnea (OSA).
Choice B rationale:
The CPAP device typically delivers consistent pressure throughout both inhalation and exhalation. It does not deliver less pressure during exhalation. The purpose of CPAP is to maintain a constant pressure to keep the airway open during both phases of the respiratory cycle.
Choice C rationale:
The CPAP device does not require an invasive ventilation tube. It uses a mask that covers the nose or both the nose and mouth to deliver positive airway pressure. It is non-invasive and is designed to keep the airway open by delivering pressurized air.

A. exercise in the mornings. B. take a nap during the day. C. drink wine. D. smoke cigarettes.

Correct Answer is A

Explanation

Choice A rationale:

The nurse recommends that normal sleep and rest patterns can best be acquired by suggesting that the patient exercises in the mornings. Morning exercise can help regulate the circadian rhythm and improve sleep-wake patterns. It helps to reset the internal body clock, making it easier to fall asleep at night. However, exercise should not be too close to bedtime, as it may have a stimulating effect.

Choice B rationale:

Taking a nap during the day may provide a short-term boost in alertness but is not recommended as the primary method to acquire normal sleep and rest patterns. Daytime naps should be brief (20-30 minutes) and should not interfere with nighttime sleep. Excessive daytime napping can disrupt the regular sleep cycle.

Choice C rationale:

Drinking wine is not a recommended approach for acquiring normal sleep and rest patterns. Alcohol consumption, especially in the evening, can disrupt sleep cycles and negatively affect the quality of sleep. It may lead to frequent awakenings during the night and contribute to sleep disturbances.

Choice D rationale:

Smoking cigarettes is not a recommended approach for acquiring normal sleep and rest patterns. Nicotine is a stimulant that can interfere with sleep by increasing alertness and heart rate. Smoking can contribute to sleep difficulties and should be avoided, especially close to bedtime. .
