A nurse is caring for a newborn who has received erythromycin eye ointment as prophylaxis for ophthalmia neonatorum.

What should the nurse monitor for as a potential adverse reaction to this medication?

Hypersensitivity

Glaucoma

Cataracts

Strabismus

Answer and Explanation

The Correct Answer is A

The correct answer is choice A. Hypersensitivity. Erythromycin eye ointment is an antibiotic that can cause allergic reactions in some newborns, such as irritation, redness, swelling, or cloudy eyes.

This is a potential adverse reaction to this medication that the nurse should monitor for.

Choice B. Glaucoma is wrong because glaucoma is a condition that causes increased pressure in the eye and can damage the optic nerve.

It is not caused by erythromycin eye ointment.

Choice C. Cataracts is wrong because cataracts are a condition that causes clouding of the lens of the eye and can impair vision.

It is not caused by erythromycin eye ointment.

Choice D. Strabismus is wrong because strabismus is a condition that causes misalignment of the eyes and can affect depth perception.

It is not caused by erythromycin eye ointment.

Erythromycin eye ointment is used to prevent ophthalmia neonatorum, which is an infection of the eye surface that affects newborns within the first month of life. It can be caused by bacteria such as chlamydia or gonorrhea that can enter the baby’s eyes during childbirth and cause permanent damage to the corneas. Erythromycin eye ointment can help prevent vision loss caused by these bacteria.

Correct Answer is A

Explanation

The correct answer is choice A.Factor II, also known as prothrombin, is one of the coagulation factors that are activated by vitamin K.Vitamin K is a cofactor for the carboxylation of specific glutamic acid groups in coagulation factors II, VII, IX, and X.

This process is essential for the activation of these factors in the coagulation cascade.

Choice B is wrong because factor V is not a vitamin K-dependent coagulation factor.

Factor V is activated by thrombin and acts as a cofactor for factor Xa in the conversion of prothrombin to thrombin.

Choice C is wrong because factor VIII is not a vitamin K-dependent coagulation factor.

Factor VIII is activated by thrombin and acts as a cofactor for factor IXa in the activation of factor X.

Choice D is wrong because factor XI is not a vitamin K-dependent coagulation factor.

Factor XI is activated by factor XIIa and activates factor IX in the intrinsic pathway of coagulation.

Normal ranges for coagulation factors are:

• Factor II: 70-120% of normal activity

• Factor V: 50-150% of normal activity

• Factor VIII: 50-150% of normal activity

• Factor IX: 50-150% of normal activity

• Factor X: 70-140% of normal activity

• Factor XI: 70-150% of normal activity

A. “We will change his diaper every 3 to 4 hours.” B. “We will wash his penis with soap and water daily.” C. “We will apply petroleum jelly on his penis with each diaper change.” D. “We will call his doctor if we see any signs of infection.”

Correct Answer is B

Explanation

The correct answer is choice B. Washing the penis with soap and water daily can irritate the circumcision site and delay healing.

The parents should only use warm water to gently clean the area and pat it dry.

They should avoid using soap, alcohol, or peroxide on the wound.

Choice A is wrong because changing the diaper every 3 to 4 hours is recommended to prevent infection and keep the area clean and dry.

Choice C is wrong because applying petroleum jelly on the penis with each diaper change can protect the wound from sticking to the diaper and reduce friction.

Choice D is wrong because calling the doctor if they see any signs of infection, such as redness, swelling, pus, foul odor, or fever, is a correct action.
