A patient has received a new prescription for levothyroxine.
Which statement made by the patient indicates that the education was effective?

Avoid the use of iron supplements.

Consume foods that are high in iodine.

Take medication on an empty stomach.

Administer levothyroxine at bedtime.

Answer and Explanation

The Correct Answer is C

Choice A rationale

Iron supplements can interfere with the absorption of levothyroxine, reducing its effectiveness. However, this doesn’t mean that iron should be completely avoided. It’s generally recommended to take iron supplements and levothyroxine at different times of the day.

Choice B rationale

While iodine is a key component of thyroid hormones, consuming foods high in iodine doesn’t necessarily improve the effectiveness of levothyroxine. In fact, excessive iodine intake can sometimes cause or worsen hypothyroidism.

Choice C rationale

Levothyroxine should be taken on an empty stomach, typically 30 minutes to an hour before breakfast. This allows for optimal absorption of the medication.

Choice D rationale

Although it’s not harmful to take levothyroxine at bedtime, studies suggest that taking it on an empty stomach in the morning may allow for better absorption.

Correct Answer is ["42"]

Explanation

To calculate the infusion rate in gtt/min, we first need to calculate the infusion rate in mL/hr. The formula for this is:

Step 1: Calculate the infusion rate in mL/hr

Infusion rate (mL/hr)=Total time (hr)Total volume (mL) Substituting the given values: Infusion rate (mL/hr)=2 hr mL=250 mL/hr

Step 2: Convert the infusion rate from mL/hr to gtt/min Infusion rate (gtt/min)=60 min/hrInfusion rate (mL/hr)×Drop factor (gtt/mL).

Substituting the given values: Infusion rate (gtt/min)=60 min/hr mL/hr×10 gtt/mL ≈42 gtt/min Therefore, the nurse should regulate the infusion to approximately 42 gtt/min.

A. Serum potassium level of 3.8 mEq/L (3.8 mmol/L) B. Hemoglobin level of 13.5 g/dL (135 g/L). C. Serum glucose level of 120 mg/dL (6.7 mmol/L) D. Serum ammonia level of 30 Mcg/dL (17.62 Mermol/L)

Correct Answer is A

Explanation

Choice A rationale

Sodium polystyrene sulfonate is a medication used to treat high levels of potassium in the blood, a condition known as hyperkalemia. Hyperkalemia is a common complication of acute kidney injury (AKI). The medication works by exchanging sodium ions for potassium ions in the intestine, which are then excreted from the body. Therefore, a decrease in serum potassium levels to within the normal range (3.5-5.0 mEq/L) would indicate that the medication has been effective.

Choice B rationale

Hemoglobin levels are not directly affected by sodium polystyrene sulfonate. Hemoglobin is a protein in red blood cells that carries oxygen. While it’s an important indicator of overall health, changes in hemoglobin levels would not indicate whether treatment for hyperkalemia is working.

Choice C rationale

Sodium polystyrene sulfonate does not directly affect glucose levels. While it’s important to monitor glucose levels in patients with kidney disease, changes in glucose would not indicate whether treatment for hyperkalemia is working.

Choice D rationale

Sodium polystyrene sulfonate does not directly affect ammonia levels. While elevated ammonia levels can occur in certain conditions, such as liver disease, changes in ammonia levels would not indicate whether treatment for hyperkalemia is working.
