A charge nurse is teaching new staff members about factors that increase a client’s risk to become violent.

Which of the following risk factors should the nurse include as the best predictor of future violence?

I will need to keep my hand elevated above my heart for several days.” This statement indicates that the client understands the importance of reducing swelling and inflammation in the affected hand after carpal tunnel surgery.

Elevation promotes venous return and prevents fluid accumulation in the tissues.

Choice A is wrong because applying heat for the first 24 hours can increase blood flow and swelling in the hand, which can cause more pain and delay healing. Ice packs are recommended for the first 24 to 48 hours to reduce inflammation.

Choice B is wrong because the client should not avoid using the affected hand for 4 to 6 weeks, as this can lead to stiffness, muscle atrophy, and decreased range of motion. The client should move the fingers periodically and perform gentle exercises as prescribed by the surgeon or physical therapist.

Choice C is wrong because numbness and tingling in the hand are signs of nerve compression, which is the main cause of carpal tunnel syndrome.

The client should expect these symptoms to improve or resolve after surgery, not persist or worsen. If the client experiences numbness and tingling after surgery, they should report it to the surgeon as it may indicate a complication such as nerve injury or hematoma.

Normal ranges for grip strength, pinch strength, and keypinch strength vary depending on age, sex, and hand dominance. However, a general reference for grip strength is 20 to 40 kg for men and 15 to 30 kg for women. For pinch strength, it is 6 to 12 kg for men and 5 to 10 kg for women. For keypinch strength, it is 4 to 8 kg for men and 3 to 7 kg for women.

These values may be lower in older adults or people with chronic conditions.

The client should expect some loss of strength in the affected hand after surgery, but it should gradually improve with rehabilitation.

The correct answer is choice D. The nurse should determine if the client’s health care surrogate is aware of the risks and benefits of the procedure. A health care surrogate is a person who is authorized to make health care decisions for a client who is unable to do so. The nurse has a legal and ethical responsibility to ensure that the client’s surrogate has given informed consent for the surgery, which means that they have received adequate information about the procedure, its purpose, its risks, its benefits, and its alternatives.

Choice A is wrong because sending the unsigned informed consent form to the facility’s risk manager does not ensure that the client’s surrogate has given informed consent. The risk manager is not involved in the consent process and cannot authorize the surgery without the surrogate’s consent.

Choice B is wrong because ensuring that the client’s family supports the provider’s decision for surgery is not the same as obtaining informed consent from the surrogate.

The family may have different opinions or preferences than the surrogate, and the surrogate may not agree with the provider’s decision. The nurse should respect the surrogate’s autonomy and authority to make decisions for the client.

Choice C is wrong because determining if the procedure is medically necessary for the client is not the nurse’s role.

The provider is responsible for determining the medical necessity of the surgery and explaining it to the surrogate. The nurse should not question or interfere with the provider’s judgment unless there is evidence of negligence or malpractice.
