A nurse is planning care for a client who has hyponatremia and is receiving IV fluid therapy with 3% sodium chloride solution. Which of the following interventions should the nurse include in the plan? (Select all that apply.)

Administer the solution via a central line.

Monitor serum sodium levels every 4 hours.

Titrate the infusion rate according to urine output.

Assess for signs of fluid overload.

Keep an accurate intake and output record.

Answer and Explanation

Correct Answer : A,B,D,E

Choice A reason:

Administer the solution via a central line. This is correct because 3% sodium chloride solution is a hypertonic solution that can cause phlebitis and tissue damage if infused peripherally. A central line can deliver the solution more safely and effectively.

Choice B reason:

Monitor serum sodium levels every 4 hours. This is correct because serum sodium levels can indicate the effectiveness of the therapy and the risk of complications such as hypernatremia or cerebral edema. The normal range of serum sodium is 135 to 145 mEq/L.

Choice C reason:

Titrate the infusion rate according to urine output. This is incorrect because the infusion rate of 3% sodium chloride solution should be titrated according to serum sodium levels, not urine output. Urine output can be affected by other factors such as renal function, fluid intake, and diuretics.

Choice D reason:

Assess for signs of fluid overload. This is correct because 3% sodium chloride solution can cause fluid shifts from the intracellular and interstitial spaces to the intravascular space, leading to fluid overload. Signs of fluid overload include cough, dyspnea, crackles, tachypnea, tachycardia, elevated blood pressure, bounding pulse, elevated central venous pressure (CVP), weight gain, edema, neck and hand vein distention, altered level of consciousness, and decreased hematocrit.

Choice E reason:

Keep an accurate intake and output record. This is correct because intake and output records can help monitor the fluid balance and identify any excesses or deficits. Intake includes oral fluids, intravenous fluids, tube feedings, and blood products. Output includes urine, stool, vomitus, drainage, and insensible losses.

Correct Answer is ["A","B","C","D"]

Explanation

Choice A reason: Pneumothorax: This is a condition where air accumulates in the pleural space, causing the lung to collapse. It can occur during insertion of a central venous catheter if the needle or catheter punctures the lung or the pleura.

Choice B reason:. Air embolism. This is a condition where air bubbles enter the bloodstream and obstruct blood flow. It can occur during insertion, removal or maintenance of a central venous catheter if air enters the catheter or the vein.

Choice C reason:. Catheter-related bloodstream infection. This is an infection that occurs when microorganisms colonize the catheter or the insertion site and enter the bloodstream. It can cause fever, chills, sepsis and other serious complications. It can be prevented by using strict aseptic technique and following infection control guidelines.

Choice D reason:. Catheter occlusion. This is a condition where the catheter lumen becomes blocked by blood clots, fibrin sheaths, precipitates or kinks. It can impair the infusion or withdrawal of fluids and medications. It can be prevented by flushing the catheter regularly with saline or heparin solutions.

Choice E reason: Hematoma formation. This is a condition where blood accumulates under the skin or in the tissues around the insertion site. It can occur due to bleeding from the punctured vein or artery, or from trauma to the site. It can cause pain, swelling, bruising and infection.

A. pH 7.50, PaCO2 40 mm Hg, HCO3- 30 mEq/L. B. pH 7.35, PaCO2 35 mm Hg, HCO3- 24 mEq/L. C. pH 7.25, PaCO2 50 mm Hg, HCO3- 26 mEq/L. D. pH 7.30, PaCO2 30 mm Hg, HCO3- 18 mEq/L.

Correct Answer is A

Explanation

Choice A reason:

pH 7.50, PaCO2 40 mm Hg, HCO3- 30 mEq/L. This choice is correct because it shows a high pH, a normal PaCO2, and a high HCO3-, which are consistent with metabolic alkalosis. Metabolic alkalosis occurs when there is a loss of acid or a gain of base in the body fluids, such as from prolonged nasogastric suctioning. The kidneys try to compensate by excreting more bicarbonate, but this process is slow and incomplete.

Choice B reason:

pH 7.35, PaCO2 35 mm Hg, HCO3- 24 mEq/L. This choice is incorrect because it shows normal values for pH, PaCO2, and HCO3-, which indicate no acid-base imbalance. A client with metabolic alkalosis would have an elevated pH and bicarbonate level.

Choice C reason:

pH 7.25, PaCO2 50 mm Hg, HCO3- 26 mEq/L. This choice is incorrect because it shows a low pH, a high PaCO2, and a normal HCO3-, which are consistent with respiratory acidosis. Respiratory acidosis occurs when there is impaired gas exchange or hypoventilation, leading to an accumulation of carbon dioxide in the blood. The kidneys try to compensate by retaining more bicarbonate, but this process is slow and incomplete.

Choice D reason:

pH 7.30, PaCO2 30 mm Hg, HCO3- 18 mEq/L. This choice is incorrect because it shows a low pH, a low PaCO2, and a low HCO3-, which are consistent with metabolic acidosis. Metabolic acidosis occurs when there is a gain of acid or a loss of base in the body fluids, such as from diabetic ketoacidosis or diarrhea. The lungs try to compensate by increasing the rate and depth of breathing to expel more carbon dioxide, but this process is fast and limited.
