A nurse in the emergency department is caring for a patient who was injured in a motor-vehicle crash. The patient reports dyspnea and severe pain.
The nurse notes that the patient’s chest moves inward during inspiration and bulges out during expiration. The nurse should identify this finding as which of the following?

Choice A rationale

Providing a diet containing 2 g of sodium per day is not typically part of the treatment for SIADH. In fact, increasing sodium intake could potentially worsen hyponatremia, a common condition in SIADH7.

Choice B rationale

Administering desmopressin acetate 0.2 mg orally is not typically part of the treatment for SIADH. Desmopressin is a synthetic form of ADH, and administering this medication could potentially worsen the symptoms of SIADH, which is characterized by an overproduction of ADH7.

Choice C rationale

Restricting fluid intake to 1,000 mL per day is often part of the treatment for SIADH. This helps to correct the imbalance of water in the body, which is a common issue in SIADH8.

Choice D rationale

Maintaining an IV of 0.45% sodium chloride is not typically part of the treatment for SIADH. This type of IV fluid is hypotonic, meaning it has a lower concentration of solutes (like sodium) than the blood. This could potentially worsen the hyponatremia seen in SIADH7.

Essential

1. Monitoring respiratory rate closely: The client is breathing rapidly and appears anxious, making close monitoring crucial to ensure timely intervention and management of respiratory issues.

2. Providing reassurance and calming interventions: The client is anxious and discomforted. Providing reassurance and calming interventions is important to address their immediate emotional and psychological needs.

3. Checking electrolyte levels regularly: Given the client's symptoms and the need for ongoing monitoring, checking electrolyte levels is essential for managing their condition effectively.

Nonessential

1. Administering antiemetic medication: While helpful for managing nausea, this action is not immediately critical compared to other interventions that address more urgent needs.

Contraindicated

1. Encouraging the client to sit up without assistance: The client feels faint and is unsteady when sitting up. Encouraging them to sit up without assistance could be dangerous and may increase the risk of falls or injuries.

2. Increasing IV fluid rate: The current IV fluid rate is prescribed by the provider. Increasing it without further assessment could lead to complications and should be avoided unless directed by a healthcare provider.
