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 A

Explanation

Choice A reason:

Decreased urine specific gravity indicates improvement in hydration status. Urine specific gravity is a measure of the concentration of solutes in the urine. It reflects the ability of the kidney to concentrate or dilute urine. A high urine specific gravity (>1.030) indicates concentrated urine, which can be caused by dehydration, reduced renal blood flow, or increased fluid loss. A low urine specific gravity (<1.010) indicates diluted urine, which can be caused by overhydration, diuretic use, or impaired renal function. A normal urine specific gravity ranges from 1.010 to 1.030.

Choice B reason:

Increased hematocrit level indicates worsening of dehydration. Hematocrit is the percentage of red blood cells in the total blood volume. It is affected by the plasma volume and the number of red blood cells. A high hematocrit (>47% for males and >42% for females) indicates hemoconcentration, which can be caused by dehydration, polycythemia, or hypoxia. A low hematocrit (<37% for males and <32% for females) indicates hemodilution, which can be caused by overhydration, anemia, or hemorrhage. A normal hematocrit ranges from 37% to 47% for males and 32% to 42% for females.

Choice C reason:

Decreased skin turgor indicates persistent dehydration. Skin turgor is the elasticity of the skin that reflects its hydration status. It is assessed by pinching a fold of skin on the chest, abdomen, or forearm and releasing it. Normally, the skin should return to its original position in less than 3 seconds. If the skin remains elevated or takes longer to return, it indicates poor skin turgor, which can be caused by dehydration, aging, or edema.

Choice D reason:

Increased serum osmolarity indicates worsening of dehydration. Serum osmolarity is a measure of the concentration of solutes in the blood plasma. It reflects the balance between water and electrolytes in the body fluids. A high serum osmolarity (>300 mOsm/kg) indicates hyperosmolarity, which can be caused by dehydration, hypernatremia, hyperglycemia, or mannitol infusion. A low serum osmolarity (<280 mOsm/kg) indicates hypoosmolarity, which can be caused by overhydration, hyponatremia, syndrome of inappropriate antidiuretic hormone secretion (SIADH), or diuretic use. A normal serum osmolarity ranges from 280 to 300 mOsm/kg.

A. Monitor blood glucose levels. B. Check for signs of phlebitis at the IV site. C. Assess for fluid overload. D. Evaluate serum sodium levels. E. Observe for signs of hypoglycemia.

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

Explanation

Choice A reason:

The nurse should monitor blood glucose levels because dextrose 10% in water (D10W) is a hypertonic solution that contains glucose and can raise the blood sugar level of the patient. The nurse should check the blood glucose level before and after administering D10W to prevent hyperglycemia or hypoglycemia.

Choice B reason:

The nurse should check for signs of phlebitis at the IV site because D10W is acidic and can cause venous irritation. Phlebitis is inflammation of the vein that can result from chemical, mechanical or bacterial causes. Signs of phlebitis include pain, redness, swelling, warmth and tenderness at the IV site.

Choice C reason:

The nurse should assess for fluid overload because D10W is quickly metabolized, leaving behind water that can move into the interstitial space. Fluid overload can cause edema, dyspnea, crackles, distended neck veins, increased blood pressure and decreased urine output. The nurse should monitor the intake and output, vital signs, weight and breath sounds of the patient.

Choice D reason:

The nurse does not need to evaluate serum sodium levels because D10W does not contain sodium or affect the sodium balance of the patient. D10W is used to provide some nutrition with glucose, not to correct electrolyte imbalances.

Choice E reason:

The nurse does not need to observe for signs of hypoglycemia because D10W is unlikely to cause hypoglycemia unless there is a sudden interruption or discontinuation of the infusion. Hypoglycemia is a low blood sugar level that can cause shakiness, diaphoresis, confusion, weakness, hunger and headache. The nurse should monitor the blood glucose level and administer D10W at a steady rate to prevent hypoglycemia.
