A nurse is reinforcing teaching about a transcutaneous electrical nerve stimulation (TENS) unit for a client who has a herniated intervertebral disk. Which of the following statements by the client indicates an understanding of the teaching?

"The TENS unit administers a continuous dose of pain medication."

"I will need to charge the TENS unit for 2 hours each day."

"The TENS unit should be applied at least 6 inches from the actual site of my pain."

"I should adjust the TENS unit until I feel a tingling sensation."

Answer and Explanation

The Correct Answer is D

The correct answer is choice D, "I should adjust the TENS unit until I feel a tingling sensation." This is an appropriate statement that indicates the client understands how to use the TENS unit. The TENS unit works by sending electrical impulses to the nerves to block pain signals. The client should adjust the unit until they feel a tingling sensation, which is the desired effect.

"The TENS unit administers a continuous dose of pain medication" is not the correct answer because the TENS unit does not administer medication.

"I will need to charge the TENS unit for 2 hours each day" is not the correct answer because the TENS unit is battery operated and does not need to be charged.

"The TENS unit should be applied at least 6 inches from the actual site of my pain" is not the correct answer because the electrodes should be placed directly on the site of the pain.

A. Metabolic acidosis B. Respiratory acidosis C. Respiratory alkalosis D. Metabolic alkalosis

Correct Answer is B

Explanation

This ABG result indicates that the client has an excess of carbon dioxide (CO2) due to hypoventilation.

A. "Metabolic acidosis" is an incorrect answer because the pH is low and the HCO3 is within normal range.

C. "Respiratory alkalosis" is an incorrect answer because the pH is low and the PaCO2 is elevated.

D. "Metabolic alkalosis" is an incorrect answer because the HCO3 is within normal range, and the pH is low.

Explanation: The ABG result shows a low pH, elevated PaCO2, and normal HCO3, indicating respiratory acidosis. This condition can be caused by conditions that affect breathing, such as pneumonia, asthma, or chronic obstructive pulmonary disease (COPD).
