Which of the following would the nurse have readily available for a client who is receiving magnesium sulfate to treat severe preeclampsia?

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.

Choice A rationale:

Mixing insulins in a vial is generally not recommended unless specifically instructed by the healthcare provider. It can alter the effectiveness of the insulins and increase the risk of dosage errors.

Premixed insulins, which are already combined in a specific ratio, are available if a combination of insulins is needed.

However, in this case, the patient is instructed to administer regular and NPH insulin separately, indicating that they should not be mixed in a vial.

Choice B rationale:

Insulin can be injected into various subcutaneous sites, including the abdomen, thighs, upper arms, and buttocks.

There is no specific requirement to inject mixed insulin into the buttocks only.

The choice of injection site can be based on individual preferences, absorption rates, and the presence of lipohypertrophy (thickening of the subcutaneous tissue due to repeated injections).

Choice C rationale:

Drawing up NPH insulin first could lead to contamination of the regular insulin vial with NPH insulin.

NPH insulin is a suspension, and drawing it up first could introduce some of its particles into the regular insulin vial, potentially altering its absorption and action profile.

Choice D rationale:

It's crucial to draw up the regular insulin first to prevent contamination of the regular insulin vial with NPH insulin. The following steps outline the correct procedure:

Wash hands thoroughly with soap and water.

Inspect the insulin vials for clarity, expiration date, and any damage.

Roll the NPH insulin vial gently between the palms to resuspend the insulin particles (if applicable). Wipe the rubber stoppers of both vials with an alcohol swab.

Using a sterile syringe, withdraw air into the syringe equal to the amount of regular insulin to be drawn.

Inject the air into the regular insulin vial, keeping the needle tip above the fluid level to avoid creating bubbles. Invert the regular insulin vial and withdraw the prescribed dose of regular insulin.

Without injecting air into the NPH insulin vial, withdraw the prescribed dose of NPH insulin. Administer the insulin as directed, using proper injection technique.
