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 B

Explanation

Choice A: Hypercalcemia. This is a condition of having too much calcium in the blood. It can cause muscle weakness, constipation, nausea, vomiting, confusion, and irregular heartbeat. However, it does not typically cause paresthesias (tingling or numbness), diarrhea, or crackles in the lungs.

Choice B:

Hypokalemia. This is a condition of having too low potassium in the blood. It can cause muscle weakness, paresthesias, irregular heartbeat, shallow respirations, and increased risk of digoxin toxicity (a medication used to treat heart failure) It can also cause vomiting and diarrhea, which can worsen the potassium loss. This choice matches the symptoms of the patient.

Choice C:

Hypermagnesemia. This is a condition of having too much magnesium in the blood. It can cause muscle weakness, nausea, vomiting, low blood pressure, bradycardia (slow heart rate), and respiratory depression. However, it does not usually cause paresthesias, diarrhea, or crackles in the lungs.

Choice D:

Hypophosphatemia. This is a condition of having too low phosphate in the blood. It can cause muscle weakness, bone pain, rickets (softening of bones), and impaired cellular function. However, it does not typically cause paresthesias, irregular heartbeat, shallow respirations, or crackles in the lungs.

A. Serum glucose 600 mg/dL. B. Serum bicarbonate 28 mEq/L. C. Serum potassium 2.5 mEq/L. D. Serum sodium 150 mEq/L.

Correct Answer is A

Explanation

Choice A reason:

Serum glucose 600 mg/dL. This is an expected finding for a client who has diabetic ketoacidosis (DKA) DKA results from a deficiency of insulin, which leads to hyperglycemia and ketosis. The normal range for serum glucose is 70 to 110 mg/dL.

Choice B reason:

Serum bicarbonate 28 mEq/L. This is not an expected finding for a client who has DKA. A client who has DKA experiences ketosis, which results in ketones in the urine and blood. The nurse should expect a client who has DKA to have an HCO3- less than 15 mEq/L. This decreased value is due to an increased production of ketones, which results in metabolic acidosis. The normal range for serum bicarbonate is 22 to 26 mEq/L.

Choice C reason:

Serum potassium 2.5 mEq/L. This is not an expected finding for a client who has DKA. A client who has DKA experiences osmotic diuresis and subsequent dehydration, which can cause electrolyte imbalances. The nurse should expect a client who has DKA to have elevated serum potassium levels due to the movement of potassium from the intracellular to the extracellular space in response to acidosis. The normal range for serum potassium is 3.5 to 5 mEq/L.

Choice D reason:

Serum sodium 150 mEq/L. This is not an expected finding for a client who has DKA. A client who has DKA experiences osmotic diuresis and subsequent dehydration, which can cause electrolyte imbalances. The nurse should expect a client who has DKA to have decreased serum sodium levels due to the dilutional effect of excess glucose in the blood. The normal range for serum sodium is 136 to 145 mEq/L.
