A patient experiences residual effects following an acute attack of Ménière's disease and receives a new prescription for an antihistamine. Which assessment finding indicates that the medication is effective?
Headache rated at 0 on 0 to 10 scale.
Oxygen saturation level of 99%.
Ambulates easily without vertigo.
Blood pressure of 120/80 mm Hg.
The Correct Answer is C
Choice A: A headache rated at 0 on 0 to 10 scale is not a specific indicator of the effectiveness of an antihistamine. A headache may be caused by other factors, such as dehydration, stress, or sinus congestion.
Choice B: Oxygen saturation level of 99% is a normal finding and does not reflect the effect of an antihistamine. Oxygen saturation measures the amount of oxygen in the blood and can be affected by respiratory conditions, altitude, or smoking.
Choice C: Ambulating easily without vertigo is a sign that the antihistamine is effective. Vertigo is a common symptom of Ménière's disease, which is a disorder of the inner ear that causes episodes of spinning sensation, hearing loss, and tinnitus. Antihistamines can help reduce the fluid buildup in the inner ear and relieve vertigo.
Choice D: Blood pressure of 120/80 mm Hg is a normal finding and does not indicate the effect of an antihistamine. Blood pressure measures the force of blood against the walls of the arteries and can be influenced by factors such as heart rate, cardiac output, blood volume, and vascular resistance.

Explanation
To answer this question, we need to find the rate of infusion in milliliters per hour (mL/hr) that will deliver 1 liter (1000 mL) of 0.9% sodium chloride, USP intravenously (IV) over 10 hours. We can use the following formula to calculate the rate:
Rate(mL/hr)=Volume(mL)/Time(hr)
Plugging in the given values, we get:
Rate(mL/hr)=1000mL/10hr
Simplifying, we get:
Rate= 100mL/hr
Correct Answer is C
Explanation
Choice A reason: An abdominal catheter is used for peritoneal dialysis, not hemodialysis. Hemodialysis requires access to a large blood vessel, usually in the arm or leg.
Choice B reason: Routine medications may need to be adjusted or avoided before or after hemodialysis, depending on their effects on blood pressure, fluid balance, and electrolytes.
Choice C reason: Insulin dosage may need to be reduced during hemodialysis because insulin is removed by the dialyzer and blood glucose levels may drop. This is the correct statement to include in client education.
Choice D reason: Potassium-rich foods should be limited in the diet of clients with chronic kidney disease and hemodialysis, because potassium can build up in the blood and cause cardiac arrhythmias.
