A nurse in an emergency department is caring for a client who has diabetic ketoacidosis (DKA) and a blood glucose level of 925 mg/dL. The nurse should anticipate which of the following prescriptions from the provider?

0.9% sodium chloride IV bolus The nurse should expect a prescription for an IV bolus of 0.9% sodium chloride to be administered at 15 to 20 mL/kg/hr for the first hour to restore volume and maintain perfusion to the vital organs.

A nurse is preparing to administer valproic acid 400 mg PO bid for migraine headaches. Available is valproic acid 250 mg/5mL. How many mL should the nurse administer per dose? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

8 mL

A nurse is assessing four clients for fluid balance. The nurse should identify that which of the following clients is exhibiting manifestations of dehydration?

A client who has a temperature of 39° C (102° F) This temperature is greater than the expected reference range of 36° C (96.8° F) to 37° C (98.6° F). An elevated temperature is a manifestation of dehydration.

A nurse is reviewing a client's laboratory values and discovers the client has a serum potassium of 6.2 mEq/L. Which of the following interventions should the nurse anticipate?

Administering sodium polystyrene sulfonate. The nurse should expect to administer sodium polystyrene sulfonate, which absorbs excessive potassium and excretes it through the stool. Other treatments include hemodialysis and IV glucose and insulin.

A nurse in a provider's office is reviewing the laboratory results of a client who takes furosemide for hypertension. The nurse notes that the client's potassium level is 3.3 mEq/L. The nurse should monitor the client for which of the following complications?

Cardiac dysrhythmias This client's potassium level is below the expected reference range. Hypokalemia can cause a number of cardiac effects including flattened T waves, prominent U waves, and S-T depression.

A nurse is caring for a client who has a postoperative ileus and an NG tube that has drained 2,500 mL in the past 6 hr. Which of the following electrolyte imbalances should the nurse monitor the client for?

Decreased potassium level Hypokalemia is an electrolyte imbalance in which the serum potassium level is less than 3.5 mEq/L. Hypokalemia may be the result of diuretic use, diarrhea, vomiting, and prolonged nasogastric suctioning.

A nurse is reviewing the laboratory test results from a client who has prerenal acute kidney injury (AKI). Which of the following electrolyte imbalances should the nurse expect?

Hyperkalemia AKI is a loss of renal function that results in a failure to maintain homeostasis. Fluid and electrolyte balance, as well as acid-base balance, are disrupted. The nurse should expect the client to have hyperkalemia due to protein breakdown and the subsequent release of intracellular potassium in to the circulation. The kidneys' inability to filter and excrete potassium results in hyperkalemia.

A nurse is admitting a client who has a serum calcium level of 12.3 mg/dL and initiates cardiac monitoring. Which of the following findings should the nurse expect during the initial assessment?

Lethargy A serum calcium level of 12.3 mg/dL is above the expected reference range. The nurse should monitor the client for lethargy, generalized weakness, and confusion.

A nurse is caring for a client who has hypertension and has a potassium level of 6.8 mEq/L. Which of the following actions should the nurse take?

Obtain a 12-lead ECG. This client's potassium level is above the expected reference range of 3.5-5.0 mEq/L and is at risk for dysrhythmias as well as cardiac arrest. Therefore, the nurse should obtain a 12-lead ECG to monitor for cardiac changes.

A nurse is reviewing the laboratory values of a client who has respiratory acidosis. Which of the following findings should the nurse expect?

PaCO2 50 mm Hg This laboratory value is an expected finding for a client who has respiratory acidosis.

A nurse is reviewing the arterial blood gas values for a client. The pH is 7.32, PaCO2 48 mm Hg and the HCO3 is 23 mEq/L. The nurse should recognize that these findings indicate of which of the following acid base balances?

Respiratory acidosis A number of conditions can lead to respiratory acidosis, including COPD and pneumonia. In the presence of respiratory acidosis, the client's blood gas values meet the following criteria: a pH less than 7.35, a PaCO2 greater than greater 45 mg/Hg, and a HCO3 that is normal or slightly elevated (22 to 26 mEq/mL).

A nurse is caring for a client who is postoperative and whose respirations are shallow and 9/min. Which of the following acid-based imbalances should the nurse identify the client as being at risk for developing initially?

Respiratory acidosis Respiratory acidosis represents an increase in the acid component, carbon dioxide, due to inadequate excretion of it, and an increase in the hydrogen ion concentration (decreased pH) of the arterial blood. A major cause of this imbalance is hypoventilation from anesthetics or opioids.

A nurse is caring for a client who has syndrome of inappropriate antidiuretic hormone (SIADH) and a sodium level of 123 mEq/L. Which of the following prescriptions should the nurse anticipate?

Restrict fluid intake to 1,000 mL per day. Clients who have SIADH have an increased amount of antidiuretic hormone, which results in excess fluid volume. This excess fluid dilutes the sodium level in the blood, causing dilutional hyponatremia. Oral fluids are restricted in an attempt to restore the fluid balance and the sodium level in the blood. The nurse should offer this client frequent oral care to prevent discomfort and breakdown of the oral mucosa.

A nurse is reviewing the arterial blood gas results for a client in the ICU who has kidney failure and determines the client has respiratory acidosis. Which of the following findings should the nurse expect?

Widened QRS complexes A client who has respiratory acidosis is likely to cardiac changes from delayed electrical conduction through the heart, such as widened QRS complexes, tall T waves, prolonged PR intervals, and a heart rate that ranges from bradycardia to heart block.

A nurse is reviewing the arterial blood gas (ABG) results of a client who the provider suspects has metabolic acidosis. Which of the following results should the nurse expect to see?

pH below 7.35 With acidosis, the pH is below 7.35. However, the pH alone does not indicate whether the problem is metabolic or respiratory. A pH above 7.45 indicates alkalosis.
