The nurse is instilling erythromycin ointment to the lower lid of the newborn’s eyes. Why is this medication being given to the newborn?
To provide moisture.
To prevent chemical conjunctivitis.
To prevent infection.
To treat infection.
The Correct Answer is C
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:
Requesting that the patient eat lunch first if testing is further delayed is the most appropriate action to prevent hypoglycemia for the following reasons:
1. Timing of NPH Insulin Peak:
NPH insulin is an intermediate-acting insulin with a peak action time of 4-12 hours after administration.
In this case, the patient received NPH insulin at 7:00 AM, meaning its peak effect is likely to occur between 11:00 AM and 5:00 PM.
Delaying lunch beyond 1:00 PM significantly increases the risk of hypoglycemia as the insulin's action peaks without adequate food intake to balance glucose levels.
2. Ensuring Consistent Mealtimes:
Consistency in meal timing is crucial for managing blood glucose levels in diabetic patients. Delaying meals can disrupt the balance between insulin and glucose, leading to hypoglycemia.
Prioritizing lunch at the usual time, even amidst testing delays, helps maintain a more predictable glucose pattern.
3. Addressing Acute Hypoglycemia Risk:
Hypoglycemia is a serious complication of diabetes that can occur if blood glucose levels fall too low. Symptoms can include shakiness, sweating, dizziness, confusion, and even loss of consciousness.
Promptly addressing potential delays in food intake is essential to prevent hypoglycemia and its associated risks.
Rationales for other choices:
Choice B: Discontinuing the evening dose of insulin does not address the immediate risk of hypoglycemia due to the missed lunch. It could lead to hyperglycemia later in the day or overnight.
Choice C: Saving the lunch tray for later may not be feasible if testing is significantly delayed. It also does not prevent hypoglycemia in the immediate timeframe.
Choice D: While a glass of orange juice can provide a quick source of glucose, it is a short-term solution and does not replace a balanced meal. It could also lead to a rapid rise in blood glucose followed by a subsequent drop.
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.
