A nurse is teaching a client about the use of a transcutaneous electrical nerve stimulation (TENS) unit. Which of the following statements should the nurse include in the teaching?
"This device delivers heat via electrodes that are attached to the affected area."
"Adjust the dial until you feel a pins-and-needles sensation."
"You can apply the electrodes directly over sensitive areas of skin."
"This device requires access to a 220-volt outlet."
The Correct Answer is B
A. "This device delivers heat via electrodes that are attached to the affected area.": A TENS unit does not use heat for pain relief. It works by delivering low-voltage electrical impulses to the skin, stimulating nerve fibers to reduce pain perception.
B. "Adjust the dial until you feel a pins-and-needles sensation.": The intensity of the electrical stimulation should be adjusted to a comfortable level where the client feels a tingling or pins-and-needles sensation. This indicates that the nerves are being stimulated appropriately for pain relief.
C. "You can apply the electrodes directly over sensitive areas of skin.": Electrodes should not be placed on irritated, broken, or sensitive skin, as this can cause discomfort or skin damage. Placement should follow guidelines to ensure effective and safe pain management.
D. "This device requires access to a 220-volt outlet.": TENS units are battery-operated and do not require a high-voltage power source. This makes them portable and convenient for home use.

Explanation
Diabetes:
• Weight
• Blood glucose
Pancreatitis:
• None
Hyperthyroidism:
• Heart rate
• T3 level
Rationale:
• Weight: The client has experienced unintended weight loss, which is a common symptom of diabetes due to the body's inability to use glucose effectively, leading to fat and muscle breakdown.
• Heart rate: Tachycardia is a hallmark of hyperthyroidism due to increased metabolic activity and sympathetic nervous system stimulation.
• T3 level: The T3 level is within the normal range but on the higher end, which can still support hyperthyroidism when considered with other clinical findings.
• Blood glucose: An elevated blood glucose level of 250 mg/dL is consistent with diabetes, as normal fasting levels are below 106 mg/dL.
Correct Answer is A
Explanation
A. Palpate the dorsalis pedis pulse: Assessing distal pulses ensures adequate circulation to the affected extremity. Impaired blood flow can indicate compartment syndrome or vascular compromise, which are serious complications following fracture stabilization. The nurse should also monitor capillary refill, skin temperature, and sensation.
B. Maintain the affected extremity in a dependent position: Keeping the extremity in a dependent position can increase swelling and venous congestion, leading to complications such as compartment syndrome. Elevation is recommended to minimize edema and promote venous return.
C. Wrap sterile gauze on the sharp point of the pins: The pin sites should be left uncovered to allow for proper monitoring of signs of infection or loosening. Instead, pin site care should be performed per facility protocol to reduce infection risk.
D. Adjust the clamps on the fixator frame: Adjusting the external fixator clamps is outside the nurse's scope of practice. Any modifications to the device should be performed by the orthopedic provider to prevent improper alignment and complications.
