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:

Excessive NREM sleep does not cause periodic pauses in breathing. NREM (Non-Rapid Eye Movement) sleep consists of stages 1 through 4 and is characterized by a decrease in physiological activity, including a decrease in muscle tone. There is no direct association with breathing interruptions in NREM sleep.

Choice B rationale:

Insomnia is a sleep disorder characterized by difficulty falling asleep or staying asleep, but it does not involve periodic pauses in breathing. It is unrelated to the symptoms described in the question.

Choice C rationale:

Narcolepsy is a sleep disorder characterized by excessive daytime sleepiness and sudden episodes of muscle weakness (cataplexy). It is not associated with periodic pauses in breathing, as described in the question.

Choice D rationale:

Sleep apnea is the correct answer. Sleep apnea is a sleep disorder characterized by repeated episodes of paused or shallow breathing during sleep. The patient may stop breathing for brief periods, then start breathing again. This pattern is consistent with the symptoms described in the question. Sleep apnea can have serious health implications and is important to recognize and address.

A. increasing pain over several hours. B. an itchy red rash on the skin. C. confusion and inability to walk normally. D. headache and nausea.

Correct Answer is C

Explanation

Choice A rationale:
Increasing pain over several hours is not a typical sign of a fentanyl patch overdose. Fentanyl is a potent opioid, and overdose symptoms often involve respiratory depression, altered mental status, and other serious issues. While it is possible for a patient to experience increased pain if the fentanyl patch is not providing adequate pain relief, this is not a specific sign of overdose.
Choice B rationale:
An itchy red rash on the skin is not a sign of a fentanyl patch overdose but can be associated with skin irritation or allergies to the adhesive in the patch. It's important to differentiate between a skin reaction and an overdose when evaluating patients using fentanyl patches. Overdose symptoms are more severe and life-threatening.
Choice C rationale:
Confusion and the inability to walk normally are characteristic signs of a fentanyl patch overdose. Fentanyl is a potent opioid, and overdose can lead to central nervous system depression, resulting in confusion, altered mental status, and difficulty with coordination and walking. These symptoms are serious and require immediate medical attention.
Choice D rationale:
Headache and nausea are not specific signs of a fentanyl patch overdose. While opioid overdose can cause various symptoms, such as respiratory depression and altered mental status, headache and nausea are not among the primary indicators. However, individual responses to medications can vary, and some patients may experience these symptoms as part of a broader set of overdose signs.
