A nurse is caring for a client who has the following arterial blood gas results: HCO3 18 mEq/L, PaCO2 28 mm Hg, and pH 7.30. The nurse recognizes the client is experiencing which of the following acid-base imbalances?

Choice A Reason:

Activating the hospital’s emergency or rapid response system is the most appropriate first action in this scenario. The client is exhibiting signs of a potentially life-threatening condition, such as airway obstruction or severe swelling that could compromise breathing. Immediate intervention by a rapid response team can provide the necessary advanced airway management and other critical care measures to stabilize the patient. This action prioritizes the client’s airway, breathing, and circulation, which are the fundamental aspects of emergency care.

Choice B Reason:

Placing a heart monitor on the client and observing for dysrhythmias is important but not the immediate priority in this situation. While monitoring the heart is crucial, the client’s airway and breathing issues take precedence. Addressing the airway obstruction and ensuring adequate breathing should be the first step before focusing on cardiac monitoring.

Choice C Reason:

Asking the charge nurse to come see the client immediately is a reasonable action, but it may delay the necessary urgent intervention. The charge nurse may not have the advanced skills or equipment required to manage a severe airway obstruction. Activating the rapid response system ensures that a team of healthcare professionals with the appropriate expertise and equipment can respond quickly.

Choice D Reason:

Checking the client’s blood pressure and heart rate is a standard nursing assessment, but it is not the immediate priority in this emergency situation. The client’s difficulty breathing and stridor indicate a potential airway obstruction, which requires immediate attention. Ensuring the airway is clear and the client can breathe is more critical than checking vital signs at this moment.

Choice E Reason:

Providing a calm and assuring environment for the client is important for reducing anxiety and stress, but it does not address the immediate life-threatening issue. While maintaining a calm environment is beneficial, the nurse must first ensure that the client’s airway is secure and that they can breathe adequately. This can only be achieved by activating the rapid response system.

Choice A Reason:

Administering 0.45% NS (normal saline) at 50 mL/hr is not appropriate for a client with SIADH. This hypotonic solution can exacerbate the condition by increasing the water retention and further diluting the serum sodium levels, worsening hyponatremia. Instead, fluid restriction and hypertonic saline (such as 3% saline) are typically used to manage SIADH.

Choice B Reason:

Obtaining daily weight is crucial in managing SIADH. Daily weights help monitor fluid retention and detect any sudden changes in body weight, which can indicate worsening fluid overload or effective treatment. Accurate weight measurements are essential for assessing the client’s fluid balance and guiding treatment decisions.

Choice C Reason:

Maintaining seizure precautions is necessary for clients with SIADH because severe hyponatremia can lead to neurological symptoms, including seizures. Implementing seizure precautions helps ensure the client’s safety and allows for prompt intervention if a seizure occurs.

Choice D Reason:

Administering 3% saline as ordered is appropriate for treating severe hyponatremia in SIADH. Hypertonic saline helps increase serum sodium levels and reduce the risk of neurological complications. It must be administered carefully and under close monitoring to avoid rapid correction of sodium levels, which can lead to osmotic demyelination syndrome.

Choice E Reason:

Encouraging fluid intake is not appropriate for clients with SIADH. Fluid restriction is a key component of managing SIADH to prevent further dilution of serum sodium levels. Encouraging fluid intake would counteract this goal and worsen the client’s condition.
