The RN is aware that a long-term side effect of amiodarone is:
Stevens-Johnsons Syndrome.
Ventricular Tachycardia.
Pulmonary fibrosis.
QT Prolongation.
The Correct Answer is D
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 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 B
Explanation
Choice A rationale:
Incorrect. Insulin pumps should be removed before bathing or swimming to prevent damage to the device. Water can enter the pump through the infusion set or through the battery compartment, causing it to malfunction. This can lead to inaccurate insulin delivery, which can result in hyperglycemia or hypoglycemia.
Additionally, the adhesive that holds the infusion set in place may not stick well to wet skin, which can increase the risk of the infusion set falling out.
It is important to note that some insulin pumps are now waterproof and can be worn while bathing or swimming. However, it is still important to check the manufacturer's instructions before doing so.
Choice B rationale:
Correct. Even though insulin pumps deliver insulin continuously, people who use them still need to monitor their blood glucose levels regularly. This is because many factors can affect blood glucose levels, such as food intake, exercise, stress, and illness.
Monitoring blood glucose levels allows people to adjust their insulin doses as needed to keep their blood glucose levels within a target range.
Recommended frequency of blood glucose monitoring:
Before meals and snacks Two hours after meals At bedtime
Before and after exercise During times of illness or stress
Whenever they feel symptoms of hypoglycemia or hyperglycemia
Choice C rationale:
Incorrect. People who use insulin pumps still need to count carbohydrates. This is because the amount of insulin that is needed to cover a meal depends on the amount of carbohydrates in the meal.
The insulin pump can be programmed to deliver different amounts of insulin for different meals, snacks, and corrections based on carbohydrate intake. This allows for more precise insulin dosing and better blood glucose control.
Choice D rationale:
Incorrect. Insulin pumps are not designed to help people lose weight. They are designed to help people manage their blood glucose levels.
While some people may lose weight when they start using an insulin pump, this is usually due to improved blood glucose control rather than the pump itself.
