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.

Correct Answer is D
Explanation
A. Hospice care services: Hospice care is designed for clients with terminal illnesses who require end-of-life care. Crohn’s disease and an ileostomy do not indicate a terminal condition, making hospice services inappropriate for this client.
B. Long-term care facility: Long-term care facilities are for clients who need continuous medical or personal care and are unable to live independently. Most clients with an ileostomy can manage their care at home with proper education and support, making this resource unnecessary.
C. Rehabilitation center: Rehabilitation centers are primarily for clients recovering from major injuries, strokes, or surgeries that impair mobility or function. While an ileostomy requires adjustment, it does not typically necessitate inpatient rehabilitation.
D. Visiting nurse services: Home health nurses provide essential support for clients with a new ileostomy by assisting with ostomy care, monitoring for complications, and reinforcing self-care education. This service helps facilitate a smoother transition to independent ostomy management.
Correct Answer is []
Explanation
Condition:
- Rheumatoid arthritis
Actions to Take:
- Assess joints for warmth and redness.
- Assess for paresthesias.
Parameters to Monitor:
- Weight-bearing joints.
- Decreased immunity.
Rationale:
Condition Choices
- Osteoporosis: Osteoporosis primarily leads to bone demineralization and increased fracture risk rather than inflammatory joint pain, swelling, and systemic symptoms such as fever and fatigue. The client’s symptoms, including joint inflammation and subcutaneous nodules, are not characteristic of osteoporosis.
- Osteoarthritis: Osteoarthritis typically presents with asymmetric joint involvement, stiffness that worsens with activity, and crepitus in weight-bearing joints. The client’s symptoms, including symmetric joint swelling, prolonged morning stiffness, and systemic inflammation markers, are more consistent with an autoimmune disorder like rheumatoid arthritis.
- Rheumatoid arthritis: The presence of bilateral joint pain, stiffness, swelling, subcutaneous nodules, and elevated inflammatory markers (ESR and CRP) strongly suggests rheumatoid arthritis. The morning stiffness, systemic symptoms like fatigue and low-grade fever, and the impact on mobility further support this diagnosis.
- Gout: Gout is characterized by acute, episodic joint pain, typically affecting the metatarsophalangeal joint of the big toe. The client’s symptoms are more widespread and chronic, involving multiple joints and systemic inflammation, which is not typical of gout.
Actions to Take
- Assess joints for warmth and redness: Inflammation in rheumatoid arthritis leads to synovial swelling, warmth, and redness. Regular assessment helps track disease progression and the effectiveness of treatment.
- Assess for paresthesias: Chronic inflammation and joint deformities in rheumatoid arthritis can lead to nerve compression, resulting in numbness or tingling, particularly in the hands and feet.
- Assess for crepitus in weight-bearing joints: Crepitus is more commonly associated with osteoarthritis due to cartilage degeneration. While rheumatoid arthritis affects weight-bearing joints, it does so through inflammatory destruction rather than mechanical wear.
- Recommend the client spend at least 5 min outside in the sun daily: Sun exposure can help with vitamin D synthesis, but rheumatoid arthritis is not primarily related to vitamin D deficiency. This intervention is more relevant for osteoporosis management.
Parameters to Monitor
- Weight-bearing joints: Rheumatoid arthritis commonly affects the knees, hips, and other weight-bearing joints, contributing to mobility issues and falls. Monitoring joint involvement helps assess disease progression.
- Decreased immunity: Rheumatoid arthritis and its treatments, such as immunosuppressive medications, increase the risk of infections. Monitoring for signs of immunosuppression is essential for early intervention.
- Joint inflammation in the big toe: This is more indicative of gout, which presents with acute episodes of pain and swelling in the first metatarsophalangeal joint rather than the widespread, chronic inflammation seen in rheumatoid arthritis.
- Calcium and vitamin D levels: While important for bone health, these levels do not provide direct insight into rheumatoid arthritis progression. They are more relevant in osteoporosis management.
- Cervical neck pain: While rheumatoid arthritis can affect the cervical spine, particularly at the atlantoaxial joint, the primary concern is peripheral joint inflammation and systemic symptoms rather than isolated neck pain.
