A nurse on a mental health unit is caring for a client who is in restraints. Which of the following actions should the nurse take?

1. Release the client's restraints every 4 hr.
2. Check the client's status every hour.
3. Document the client's behavior leading to the initiation of the restraints.

Obtain written consent by the client for the placement of the restraints.

Deep-vein thrombosis (DVT) is a condition where a blood clot forms in a deep vein, usually in the legs. Bed rest is often recommended for clients with DVT to reduce the risk of the clot dislodging and causing a pulmonary embolism. By minimizing movement and keeping the leg elevated, the nurse can help prevent further complications.

The other options listed are incorrect:

1. Massage the affected extremity every 4 hours: Massaging the affected extremity can dislodge the clot, increasing the risk of a pulmonary embolism. It is contraindicated and should not be performed in clients with DVT.
2. Apply an ice pack to the affected extremity for 20 minutes every 2 hours: While applying cold compresses or ice packs may be useful in some situations to reduce swelling or pain, it is not recommended for clients with DVT. Heat application or cold application should be avoided because they can promote blood circulation and potentially dislodge the clot.
3. Administer aspirin for pain: Aspirin is not typically used for pain management in DVT. Anticoagulant therapy is the primary treatment for DVT, and specific anticoagulant medications are prescribed to prevent further clot formation and reduce the risk of complications.

This step is part of the process when mixing NPH and regular insulin in a single syringe. After injecting air into the NPH insulin vial, you should inject an equal amount of air (in this case, 15 units) into the regular insulin vial to maintain pressure balance. This allows for easy withdrawal of the prescribed doses of each insulin type in the same syringe without causing a vacuum in the vials.

After injecting air into the NPH insulin vial (step 1), the nurse should proceed to inject air into the regular insulin vial (step 2) before withdrawing the insulin doses in the subsequent steps.

Verifying the dosage with another nurse is not necessary in this step, as it is done prior to drawing up the insulin. However, it is good practice to have another nurse double-check the dosage before administration.

Injecting air into the regular insulin vial is not required at this stage. It is only necessary when withdrawing the regular insulin dose.

Placing the cap over the needle should be done after withdrawing the desired dose of insulin and before administering it to the client for safety and to prevent needlestick injuries.

The correct sequence when mixing NPH and regular insulin in a single syringe is as follows:

1. Inject air into the NPH insulin vial (in this case, 10 units of air).
2. Inject air into the regular insulin vial (in this case, 15 units of air).
3. Withdraw the prescribed dose of NPH insulin (10 units) from the NPH vial.
4. Withdraw the prescribed dose of regular insulin (15 units) from the regular insulin vial.

So, after injecting air into the NPH insulin vial (step 1), the nurse should proceed to inject air into the regular insulin vial (step 2) before withdrawing the insulin doses in the subsequent steps.
