A nurse is preparing to administer potassium chloride 10 mEq IV over 1 hr to a client. Available in potassium chloride 10 mEq in 100 mL of 0.9% sodium chloride. The nurse should set the infusion pump to deliver how many mL/hr? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.).

Choice A rationale:

Leflunomide is a disease-modifying antirheumatic drug (DMARD) used for rheumatoid arthritis, but it does not typically result in decreased swelling within one week. It usually takes several weeks or even months for its full effect to be observed.

Choice B rationale:

Applying hot packs directly to the joint for pain relief is not recommended for rheumatoid arthritis, as heat can exacerbate inflammation. Cold packs or other anti-inflammatory measures are more appropriate.

Choice C rationale:

Steroid medications, such as prednisone, can lead to bone density loss and an increased risk of osteoporosis. Taking calcium and vitamin D supplements helps to mitigate this risk.

Choice D rationale:

The Varicella vaccine is not directly related to rheumatoid arthritis. It is important for immune support, but it is not specifically required for rheumatoid arthritis treatment.

Choice A rationale:

The nurse's first priority in this situation should be to close the pinch clamp on the central venous catheter (CVC). This will prevent air from entering the client's vascular system and causing an air embolism, which can lead to serious complications. Once the clamp is closed, the nurse can then proceed with further assessments and interventions.

Choice B rationale:

Obtaining a prescription for stat ABGS (Arterial Blood Gas Studies) is not the first action the nurse should take in this situation. While ABGS may be relevant later to assess the client's respiratory status, the immediate concern is to prevent air embolism by closing the disconnected IV tubing.

Choice C rationale:

Placing the client in the left Trendelenburg position is not the first priority in this situation. The Trendelenburg position is used to increase venous return and is typically indicated in cases of hypotension or shock. Closing the clamp to prevent an air embolism should be the nurse's initial action.

Choice D rationale:

Checking the tubing for the placement of a locking adaptor is not the first action the nurse should take. While it is essential to ensure that the IV tubing is properly connected and secured, preventing the air from entering the CVC should take precedence in this urgent situation.
