A female client with multiple sclerosis reports having less fatigue and improved memory since she began using the herbal supplement, ginkgo biloba. Which information is most important for the nurse to include in the teaching plan for this client?

Choice B reason: Naloxone may be necessary, but first, the source of overdose (patches) must be removed to prevent further opioid absorption. After removal, the nurse should assess the severity and then administer naloxone if needed.

Choice A reason: Applying oxygen face mask is not the first action that the nurse should take in this situation, but rather a supportive measure that can be done after administering naloxone. Oxygen can help to improve the client's oxygenation and prevent hypoxia, but it will not reverse the opioid overdose.

Choice C reason: The client is exhibiting signs of opioid overdose, including respiratory depression (shortness of breath) and decreased level of consciousness (difficult to arouse). The first priority is to remove the excess morphine patches to stop further opioid absorption and prevent worsening of the overdose.

Choice D reason: Monitoring blood pressure is not the first action that the nurse should take in this situation, but rather an ongoing assessment that can be done after administering naloxone. Monitoring blood pressure can help to detect any changes in the client's hemodynamic status and guide further interventions, but it will not reverse the opioid overdose.

Choice A reason: Administering levothyroxine at bedtime is not a correct statement, as it may interfere with sleep quality and hormone absorption. Levothyroxine is a synthetic thyroid hormone that replaces or supplements low levels of natural thyroid hormone in hypothyroidism. Levothyroxine should be taken in the morning, at least 30 minutes before breakfast, to avoid insomnia and ensure optimal absorption.

Choice B reason: Consuming foods that are high in iodine is not a correct statement, as it may affect thyroid function and hormone levels. Iodine is an essential element that is needed for thyroid hormone synthesis. However, too much or too little iodine can cause thyroid disorders, such as goiter or hyperthyroidism. Levothyroxine does not require additional iodine intake, and clients should follow a balanced diet.

Choice C reason: Avoiding the use of iron supplements is a correct statement, but it is not specific to levothyroxine. Iron supplements can interfere with many medications, including levothyroxine, by reducing their absorption and efficacy. Iron supplements should be taken at least 4 hours before or after levothyroxine or other medications.

Choice D reason: Taking medication on an empty stomach is a correct statement that indicates effective education. Levothyroxine should be taken on an empty stomach, preferably in the morning, to avoid food-drug interactions and enhance absorption. Food, especially those high in fiber or calcium, can decrease levothyroxine absorption and effectiveness.
