A nurse is collecting data from a client whose arterial blood gas values reveal a pH of 7.24, PaCO2 of 53, and an HCO3 of 24. The nurse should prepare to treat the client for which of the following acid-base imbalances?

a. Restrict oral fluids to 800 to 1,000 mL/day: Hyponatremia is a characteristic finding in SIADH, and fluid restriction is a key intervention to correct the imbalance.

b. Maintain an IV of 0.45% sodium chloride: Infusing hypertonic (3%) saline may be indicated in severe cases of hyponatremia, but the initial step is fluid restriction.

c. Ensure the client receives a 2 g/day sodium diet: Dietary sodium restriction is not the primary intervention for SIADH. Fluid restriction is more critical.

d. Administer desmopressin acetate 0.2 mg orally: Desmopressin acetate is an antidiuretic

hormone and would exacerbate the retention of water, further decreasing sodium levels. It is not the appropriate intervention for this client.

a. Nausea: Nausea is a common symptom of myocardial infarction and can be associated with autonomic nervous system activation.

b. Orthopnea: Orthopnea, difficulty breathing while lying down, is more commonly associated with heart failure, not necessarily myocardial infarction.

c. Diaphoresis: Profuse sweating or diaphoresis is a common manifestation of myocardial infarction due to sympathetic nervous system activation.

d. Headache: Headache is not a typical symptom of myocardial infarction. However, some individuals may experience atypical symptoms.

e. Tachycardia: Tachycardia (rapid heart rate) is a common response to myocardial infarction and can be associated with sympathetic nervous system stimulation in response to decreased cardiac output.
