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 C
Explanation
Choice A rationale:
Erythromycin ointment does not have moisturizing properties. Its primary purpose is to prevent bacterial infection, not to provide moisture to the eyes.
While some ointments may have a slight moisturizing effect, this is not the main reason for using erythromycin ointment in newborns.
If moisture is the primary concern, other products specifically designed to lubricate the eyes would be more appropriate.
Choice B rationale:
Chemical conjunctivitis is typically caused by exposure to irritants such as chlorine in swimming pools or strong chemicals. Erythromycin ointment is not effective in preventing chemical conjunctivitis.
In fact, it could potentially worsen the irritation if used in cases of chemical conjunctivitis.
If chemical conjunctivitis is suspected, flushing the eyes with water or saline solution and seeking medical attention would be the appropriate course of action.
Choice D rationale:
Erythromycin ointment is an antibiotic, but it is not typically used to treat active infections in newborns.
If a newborn has a suspected eye infection, a healthcare provider would likely prescribe a different antibiotic eye drop or ointment that is more effective in treating the specific infection.
However, erythromycin ointment can be used as a prophylactic measure to prevent eye infections, which is why it is commonly administered to newborns shortly after birth.
Choice C rationale:
Erythromycin ointment is primarily used to prevent eye infections in newborns.
It is effective against a variety of bacteria that can cause conjunctivitis, including Neisseria gonorrhoeae (the bacteria that causes gonorrhea) and Chlamydia trachomatis (the bacteria that causes chlamydia).
These bacteria can be passed from the mother to the baby during childbirth, and if left untreated, they can cause serious eye infections that can lead to vision loss.
By applying erythromycin ointment to the newborn's eyes shortly after birth, the risk of these infections can be significantly reduced.
Correct Answer is A
Explanation
Choice A rationale:
Hypoglycemia is a critical consideration: The patient's symptoms of lethargy, diaphoresis, and combativeness, along with recent insulin administration, raise a strong suspicion of hypoglycemia (low blood sugar). Hypoglycemia can quickly progress to coma and seizures if not promptly treated, making it a high priority to assess and address.
Bedside glucose testing is rapid and reliable: A bedside finger stick blood glucose test is a quick, non-invasive, and accurate way to determine the patient's blood sugar level. It provides immediate results, allowing for prompt intervention if hypoglycemia is confirmed.
Other assessments and interventions can follow: Once hypoglycemia is ruled out or confirmed, the nurse can proceed with other assessments and interventions as needed.
Choice B rationale:
Insulin administration without blood sugar confirmation is dangerous: Administering insulin without first checking the patient's blood sugar could worsen hypoglycemia if it is already present. This could lead to severe complications, including neurological damage or even death.
Insulin timing is not a priority: While the next dose of insulin may be due, its administration is not the most urgent priority in this situation. Addressing the patient's immediate symptoms and potential hypoglycemia takes precedence.
Choice C rationale:
Naloxone is not indicated for hypoglycemia: Naloxone is an opioid antagonist used to reverse opioid overdose. It has no effect on hypoglycemia and would not be appropriate in this case.
Choice D rationale:
Oxygen therapy may not address the underlying issue: While oxygen therapy can be beneficial for patients with respiratory distress, it does not address the potential hypoglycemia in this case. If the patient's lethargy and combativeness are due to low blood sugar, oxygen therapy alone would not be sufficient treatment.
Oxygen saturation is already within normal limits: The patient's oxygen saturation (SPO2) is 97%, indicating that their oxygenation is currently adequate. Oxygen therapy would not be indicated unless there were signs of hypoxia.
