Question

The client with hyperthyroidism has a prescription for lithium carbonate (Lithobid). The client should be taught to take the medication: A. Two times per day B. With milk or meals C. With an antiemetic D. For the treatment of psychosis

Short answer

Answer: With milk or meals

Step-by-step solution

Understand the purpose of lithium carbonate

Lithium carbonate (Lithobid) is a medication primarily used to treat bipolar disorder. It is also used for the treatment of major depressive disorder and occasionally used for hyperthyroidism. It is essential to understand the purpose of the medication before moving on to the administration aspect.

Rule out incorrect options

Now that we have a better understanding of lithium carbonate, let's look at the options given and rule out the ones that are not correct: Option A: Two times per day - The frequency of lithium carbonate intake depends on the patient's condition and doctor's prescription, so we cannot be sure about this option. Option C: With an antiemetic - There is no general instruction to take lithium carbonate with an antiemetic. This is not the most appropriate answer. Option D: For the treatment of psychosis - Although lithium carbonate can be used in some cases of psychosis, it is not the primary indication for the medication. This option is not directly related to the administration of lithium carbonate, making it an incorrect choice.

Choose the correct option

Having ruled out options A, C, and D, we are left with the correct option: Option B: With milk or meals - Taking lithium carbonate with milk or meals can help reduce stomach upset caused by the medication. This is a proper administration for taking the medication, making option B the correct answer.

Key concepts

Hyperthyroidism Medication

Hyperthyroidism is a condition where the thyroid gland is overactive, producing excessive thyroid hormones. This can lead to symptoms like rapid heartbeat, weight loss, and anxiety among others. Treatment usually involves medication to slow down thyroxine production, radioiodine therapy, or even surgery in severe cases.
A common medication used in treating hyperthyroidism is methimazole, which works by inhibiting the production of thyroid hormones. Another drug, propylthiouracil, can also be employed especially in pregnancy or thyroid storm cases. However, in certain situations, the drug Lithium Carbonate, which is traditionally used for treating bipolar disorder, might be prescribed to help manage hyperthyroidism.

• This happens as lithium helps to reduce the thyroid hormone levels effectively.
• It's not a first-line treatment, but an option when other treatments aren't effective or suitable.

Understanding these medication options and their uses is crucial in developing a comprehensive treatment plan for managing hyperthyroidism.

Lithium Carbonate Administration

Lithium carbonate is primarily known for its use in managing mood disorders, but it also plays a role in treating hyperthyroidism. When administering lithium carbonate for hyperthyroidism, specific guidelines need to be followed to ensure its effectiveness and to minimize potential side effects.
One critical aspect of administration is taking the medication with meals or milk, as this can reduce gastrointestinal discomfort, a common side effect of lithium. For instance, taking lithium after a full meal might prevent nausea or stomach upset.

• Patients should also stay hydrated, as dehydration can increase lithium levels, leading to toxicity.
• Regular monitoring of lithium levels is necessary to maintain the balance required for therapeutic benefits without reaching toxic levels.

These administration tips ensure that the medication works effectively while keeping patients comfortable and safe from adverse reactions.

Pharmacology

Pharmacology is the study of how drugs interact with the body. Understanding pharmacology is essential for any healthcare professional, especially nurses, as it allows them to safely administer medications like lithium carbonate.
When examining the pharmacology of a drug such as lithium, we consider several key factors:

• How the drug is absorbed, distributed, metabolized, and excreted by the body.
• The therapeutic effects versus potential side effects.
• Interactions with other medications and food.

The mechanism by which lithium affects thyroid hormone levels is still partly unknown but is believed to involve inhibiting the release of hormones from the thyroid gland. Awareness of drug interactions is also critical. For example, NSAIDs and certain diuretics can increase lithium levels, posing a risk of toxicity.
Nurses must employ their pharmacological knowledge to ensure optimal patient outcomes when administering medications.

Nursing Exam Strategies

Preparing for the NCLEX-PN can be overwhelming, but employing effective strategies can make it manageable. Students need a solid understanding of pharmacology due to its prominence in the exam, including knowing how medications like lithium carbonate affect the body and are administered.

• Students should focus on drug classifications, side effects, and interactions.
• Practice tests are invaluable tools that can assist in identifying weaker areas requiring more focus.
• Time management techniques, such as allotting specific minutes to each question, help optimize pacing during the exam.

Another effective approach includes group studies where difficult concepts can be discussed and clarified. Incorporating active recall and spaced repetition techniques into study routines helps reinforce knowledge and ensure retention.
Ultimately, these strategies ensure better preparation and increase the likelihood of passing the exam on the first try.
