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 D

Explanation

The correct answer is D. Immediately after completion of the IV dose and 30 minutes before the next administration of the medication.

Explanation:

Peak levels measure the highest concentration of the drug in the bloodstream and should be drawn immediately after the IV infusion is completed.
Trough levels measure the lowest concentration of the drug and should be drawn 30 minutes before the next scheduled dose. This helps ensure the drug remains within therapeutic levels and prevents toxicity.

Why the other options are incorrect:

A. One hour after completion of the IV dose and one hour before the next administration – Waiting one hour for the peak level is too long and may lead to an inaccurate measurement.
B. Two hours after completion of the IV dose and two hours before the next administration – Waiting two hours for both peak and trough levels is too late for effective monitoring.
C. Thirty minutes into the administration of the IV dose and 30 minutes before the next administration – The sample drawn mid-infusion does not represent peak levels, making this method ineffective.

Key takeaway:

Proper timing of vancomycin peak and trough monitoring ensures therapeutic drug levels while minimizing nephrotoxicity and ototoxicity.

A. Administer a second dose of naloxone. B. Prepare to assist with chest tube insertion. C. Determine Glasgow Coma Scale score. D. Initiate cardiopulmonary resuscitation (CPR). .

Correct Answer is D

Explanation

The correct answer is choice D: Initiate cardiopulmonary resuscitation (CPR).

Choice D rationale: The patient's respiratory rate of 4 breaths/minute, oxygen saturation of 75%, and unresponsiveness indicate severe respiratory depression, which requires immediate intervention. CPR is the priority action to maintain circulation and oxygenation while awaiting further interventions.

Choice A rationale: Administering a second dose of naloxone may be necessary to counteract the effects of opioids. However, in this case, the patient's condition has severely deteriorated, and immediate resuscitation efforts take priority.

Choice B rationale: Preparing to assist with chest tube insertion is not the appropriate action in this situation. Chest tube insertion is used to treat conditions like pneumothorax or pleural effusion, which are not indicated in this scenario.

Choice C rationale: Determining the Glasgow Coma Scale score is useful for assessing the patient's level of consciousness but should not be the first action in this case. Ensuring adequate circulation and oxygenation through CPR is the priority.
