A patient has been prescribed levothyroxine (Synthroid) for hypothyroidism. The patient inquires if the medication should be taken with food.
What would be the most appropriate response from the nurse?
Always consume this medication with food.
This medication should be taken with a glass of milk.
Consume this medication with juice and crackers.
This medication should be taken on an empty stomach.
The Correct Answer is D
Rationale for Choice A:
It is not recommended to always consume levothyroxine with food. In fact, food can interfere with the absorption of levothyroxine, leading to decreased efficacy of the medication.
Consuming levothyroxine with food can decrease its absorption by up to 30%, which can significantly impact its ability to manage hypothyroidism symptoms.
Certain foods, such as those high in fiber, calcium, or iron, can be particularly problematic, as they can bind to levothyroxine in the gut and further reduce its absorption.
While taking levothyroxine with a small amount of food may be necessary for some individuals who experience gastrointestinal side effects, it's generally recommended to take it on an empty stomach for optimal absorption.
Rationale for Choice B:
Milk is not an ideal beverage to take with levothyroxine, as it can also interfere with absorption. Milk contains calcium, which can bind to levothyroxine and reduce its absorption.
It's best to avoid consuming milk or other calcium-rich beverages within a few hours of taking levothyroxine.
Rationale for Choice C:
Similar to milk, juice and crackers are not ideal choices to take with levothyroxine.
Juice, especially those high in acidity, can affect the absorption of levothyroxine in the gut.
Crackers, often made with refined grains, can be high in fiber, which can also interfere with absorption.
Rationale for Choice D:
Taking levothyroxine on an empty stomach, typically 30-60 minutes before breakfast, is generally recommended to ensure optimal absorption.
This allows the medication to be absorbed more efficiently in the small intestine without being affected by the presence of food.
By taking levothyroxine on an empty stomach, patients can maximize its effectiveness in treating hypothyroidism.

Correct Answer is A
Explanation
Choice A rationale:
Insulin is a protein-based hormone that is sensitive to heat and light. Exposure to high temperatures or direct sunlight can cause insulin to break down and become less effective.
Refrigeration helps to maintain the stability and potency of insulin. It is generally recommended to store unopened insulin vials in the refrigerator at a temperature between 36°F and 46°F (2°C and 8°C).
This temperature range helps to slow down the degradation process and ensure that the insulin remains effective until its expiration date.
Choice B rationale:
Insulin should never be frozen. Freezing can cause the insulin to crystallize and become unusable. Once insulin has been frozen, it cannot be thawed and used again.
Choice C rationale:
Opened vials of insulin do not need to be discarded immediately. They can be stored in the refrigerator for up to 28 days, depending on the type of insulin.
However, it is important to note the date that the vial was opened and to discard it after the recommended storage period.
Choice D rationale:
Insulin pens should be stored according to the manufacturer’s instructions. Some insulin pens can be stored at room temperature for a certain period of time, while others must be refrigerated.
It is important to read the instructions that come with the insulin pen to ensure that it is stored properly.
Correct Answer is B
Explanation
Choice A rationale:
Requesting an order for morphine sulfate IV 2 mg over 1-5 minutes would not be appropriate at this time for several reasons: The patient has already received a dose of 4 mg 15 minutes ago, and it has not been effective in relieving the chest pain.
The patient is showing signs of increased respiratory effort, which could be a sign of respiratory depression. Administering an additional dose of morphine could worsen the respiratory depression.
The patient's heart rate is 82 beats per minute, which is within the normal range.
The patient's blood pressure is 135/88 mm Hg, which is also within the normal range.
Choice C rationale:
Administering naloxone (Narcan) to counteract respiratory depression would not be appropriate at this time because the patient is not showing signs of severe respiratory depression. Naloxone is a medication that is used to reverse the effects of opioid overdose. It is typically only used in situations where the patient is experiencing life-threatening respiratory depression.
Choice D rationale:
Administering morphine sulfate IV 4 mg over 1-5 minutes would not be appropriate for the reasons listed above. It could worsen the patient's respiratory depression and potentially lead to other complications.
Choice B is the best answer because it is the most conservative and safest option. By withholding the next dose of morphine and informing the provider about the patient's symptoms, the nurse can ensure that the patient receives the appropriate care and that any potential complications are avoided.
