Which client statement demonstrates understanding of the nurse’s teaching for levothyroxine (Synthroid)?
It is best to take the medication with food to prevent gastrointestinal upset
I will take this medication first thing in the morning
I can expect to see relief of my symptoms within 1 week
I will double my dose if I gain more than 1 pound per day
The Correct Answer is B
Choice A rationale:
It is not recommended to take levothyroxine with food as it can interfere with its absorption.
Food, particularly those containing calcium or iron, can bind to levothyroxine in the gastrointestinal tract, reducing the amount of medication that is absorbed into the bloodstream.
This can lead to decreased effectiveness of the medication.
It's generally advised to take levothyroxine on an empty stomach, at least 30-60 minutes before breakfast, to ensure optimal absorption.
Choice B rationale:
Taking levothyroxine first thing in the morning, on an empty stomach, is the most effective way to ensure its absorption and consistent hormone levels throughout the day.
This aligns with the body's natural rhythm of thyroid hormone production, which typically peaks in the morning hours.
Taking the medication consistently at the same time each day helps maintain stable thyroid hormone levels, which is crucial for managing hypothyroidism effectively.
Choice C rationale:
Relief of symptoms with levothyroxine therapy often takes several weeks, not just one week.
It takes time for the body to adjust to the medication and for thyroid hormone levels to reach a therapeutic range.
Patients should be counseled to have patience and continue taking the medication as prescribed, even if they don't experience immediate symptom relief.
They should also be monitored regularly by their healthcare provider to assess their response to treatment and make any necessary adjustments to the dosage.
Choice D rationale:
Doubling the dose of levothyroxine without consulting a healthcare provider is dangerous and can lead to serious health consequences.
Overdosing on levothyroxine can cause hyperthyroidism, which can manifest as rapid heart rate, anxiety, tremors, weight loss, and other health problems.
It's essential to follow the prescribed dosage and not make any changes without the guidance of a healthcare professional.

Correct Answer is D
Explanation
Choice A rationale:
Stevens-Johnson syndrome (SJS) is a rare, serious skin condition that is typically caused by an allergic reaction to medication. While amiodarone has been associated with a few cases of SJS, it is not considered a common long-term side effect.
Choice B rationale:
Ventricular tachycardia (VT) is a type of fast heart rhythm that originates in the ventricles of the heart. Amiodarone is actually used to treat VT, so it would be counterintuitive to list it as a long-term side effect.
Choice C rationale:
Pulmonary fibrosis is a condition characterized by scarring of the lung tissue. While amiodarone can cause pulmonary toxicity, which includes pulmonary fibrosis, this is a relatively rare side effect. Moreover, it's usually associated with high doses or
long-term use of the medication.
Choice D rationale:
QT prolongation is a condition in which the heart's electrical activity takes longer than normal to recharge between beats. This can lead to a potentially fatal arrhythmia called torsades de pointes. Amiodarone is known to prolong the QT interval, and this is considered one of its most significant long-term side effects. It's important to monitor patients on amiodarone for QT prolongation and to adjust the dose or discontinue the medication if necessary.
Correct Answer is B
Explanation
Choice A rationale:
Insulin lispro is a rapid-acting insulin that begins to work within 15 minutes of injection. If administered 15 minutes after eating, it may not be able to effectively control the rise in blood glucose levels that occurs after a meal. This could lead to hyperglycemia, which can have negative short-term and long-term health consequences.
Administering insulin lispro 15 minutes after eating would delay its action and potentially lead to suboptimal blood glucose control. It's crucial to match the timing of insulin administration with the meal to ensure optimal glucose management.
Choice C rationale:
Administering insulin lispro 10 minutes after eating would also delay its action. While not as delayed as 15 minutes, it still wouldn't align with the peak of meal-related glucose absorption, potentially leading to suboptimal glucose control.
Choice D rationale:
Insulin lispro has a shorter duration of action compared to regular insulin. Administering it 30 minutes before eating could lead to hypoglycemia, a condition characterized by low blood glucose levels. Hypoglycemia can cause a variety of symptoms, including shakiness, sweating, dizziness, confusion, and even loss of consciousness.
It's essential to closely align the timing of rapid-acting insulins like insulin lispro with mealtimes to minimize the risk of hypoglycemia.
