The nurse is caring for a patient with an IV infusion in his left arm that was started 2 hours ago in the emergency department (ED) The patient complains of pain at the IV site and rates it as an 8 on a scale of 0 to 10. The nurse assesses the site and notes edema, erythema, and coolness to touch around the insertion site. What is the most appropriate action by the nurse?

Apply warm compresses to the site and elevate the arm.

Slow down the infusion rate and document the findings.

Stop the infusion, remove the IV catheter, and start a new IV in another site.

Notify the physician and obtain an order for an antihistamine.

Answer and Explanation

The Correct Answer is C

Choice A reason:

Applying warm compresses to the site and elevating the arm may help to reduce pain and swelling, but they do not address the underlying cause of the problem, which is likely infiltration or phlebitis of the IV site. Infiltration occurs when the IV fluid leaks into the surrounding tissue, causing edema, coolness, and pallor. Phlebitis occurs when the vein becomes inflamed, causing pain, erythema, and warmth. Both conditions require immediate removal of the IV catheter and restarting a new IV in another site.

Choice B reason:

Slowing down the infusion rate and documenting the findings may be appropriate actions after removing the IV catheter and starting a new IV in another site, but they are not sufficient to resolve the problem. Slowing down the infusion rate may reduce the discomfort and prevent further complications, but it does not stop the leakage or inflammation of the IV site. Documenting the findings is important for legal and quality improvement purposes, but it does not provide any intervention for the patient's pain or risk of infection.

Choice C reason:

Stopping the infusion, removing the IV catheter, and starting a new IV in another site is the most appropriate action by the nurse. This action prevents further damage to the tissue or vein, reduces the risk of infection, and restores adequate IV access for fluid and medication administration. The nurse should also apply a sterile dressing to the affected site, monitor for signs of infection or complications, and notify the physician if needed. This is the correct answer.

Choice D reason:

Notifying the physician and obtaining an order for an antihistamine is not an appropriate action by the nurse. This action implies that the patient is having an allergic reaction to the IV fluid or medication, which is not supported by the assessment findings. An antihistamine may help to reduce itching or swelling, but it does not address the cause of the pain or prevent further tissue or vein damage. The nurse should notify the physician after removing the IV catheter and starting a new IV in another site, and only if there are signs of infection or complications that require medical intervention.

Correct Answer is D

Explanation

Choice A reason:

Hypernatremia is not a likely complication of fluid therapy for diabetic ketoacidosis (DKA) Hypernatremia occurs when there is a loss of water or an excess of sodium in the body. Fluid therapy for DKA usually involves normal saline and dextrose, which do not cause hypernatremia. In fact, fluid therapy may help correct the dehydration and hyperosmolality that are associated with DKA.

Choice B reason:

Hyperkalemia is also not a likely complication of fluid therapy for DKA. Hyperkalemia occurs when there is an excess of potassium in the blood. Fluid therapy for DKA usually involves insulin infusion, which helps lower the potassium level by driving it into the cells. Insulin also helps lower the blood glucose level and reverse the acidosis that are characteristic of DKA.

Choice C reason:

Fluid volume deficit is a common manifestation of DKA, not a complication of fluid therapy. Fluid volume deficit occurs when there is a loss of fluid and electrolytes from the body due to osmotic diuresis, vomiting, and increased respiratory rate. Fluid therapy for DKA aims to restore the fluid volume and correct the electrolyte imbalances that result from fluid loss.

Choice D reason:

Cerebral edema is a potential complication of fluid therapy for DKA, especially in children and young adults. Cerebral edema occurs when there is an increase in intracranial pressure due to swelling of the brain tissue. Fluid therapy for DKA may cause cerebral edema by altering the osmotic gradient between the blood and the brain, leading to fluid shifts into the brain cells. Cerebral edema can cause neurological symptoms such as headache, confusion, seizures, and coma.

A. Decreased thirst. B. Increased urine output. C. Decreased serum sodium level. D. Increased level of consciousness. E. Decreased edema.

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

Explanation

Choice A reason:

Decreased thirst. This is a sign of improvement because hypernatremia causes increased thirst due to high sodium levels in the blood. Decreased thirst indicates that the fluid therapy has restored the normal balance of sodium and water in the body.

Choice B reason:

Increased urine output. This is a sign of improvement because hypernatremia can cause decreased urine output due to dehydration or kidney dysfunction. Increased urine output indicates that the fluid therapy has replenished the body's water and helped the kidneys excrete excess sodium.

Choice C reason:

Decreased serum sodium level. This is a sign of improvement because hypernatremia is defined as a serum sodium level higher than 145 mEq/L. Decreased serum sodium level indicates that the fluid therapy has diluted the blood and lowered the sodium concentration to within the normal range.

Choice D reason:

Increased level of consciousness. This is a sign of improvement because hypernatremia can cause confusion, lethargy, or coma due to the effects of high sodium levels on the brain. Increased level of consciousness indicates that the fluid therapy has improved the brain function and reduced the risk of brain injury.

Choice E reason:

Decreased edema. This is not a sign of improvement because hypernatremia does not cause edema, which is the accumulation of fluid in the interstitial spaces. Edema is more likely to occur in conditions such as hypervolemia (excess fluid volume) or hyponatremia (low sodium levels) Decreased edema may indicate that the fluid therapy has caused fluid overload or electrolyte imbalance, which can be harmful.
