a newborn has a meningomyelocele; the nurse should place him in which position:

Correct Answer: C

Rationale: A newborn with meningomyelocele should be placed in a prone position to prevent trauma or pressure on the lesion. Placing the newborn in the prone position helps prevent the lesion from coming in contact with surfaces and reduces the risk of infection and injury. By positioning the newborn prone, gravity will assist in closing the lesion and reducing the risk of complications. It is crucial to follow this positioning guideline to ensure the infant's safety and well-being.

Correct Answer: B

Rationale: Strabismus, or misalignment of the eyes, is a common condition in newborns due to the lack of binocularity. Binocularity refers to the ability of both eyes to focus simultaneously on a single point, which is not fully developed in newborns. As a result, it is normal for a newborn's eyes to appear misaligned at times. This lack of coordination between the eyes typically resolves as the infant's visual system matures and they develop the ability to focus both eyes together. Therefore, the presence of strabismus in a newborn is usually considered a normal finding related to the immature visual development rather than a sign of pathology such as congenital cataracts, absence of red reflex, or pupil reactivity issues.

Correct Answer: D

Rationale: The nurse should inform the mother that the baby can be discharged once the Plastibell rim falls off. The Plastibell method involves placing a small plastic ring over the foreskin, which cuts off circulation and causes the foreskin to fall off on its own within a week to 10 days after the procedure. Once the Plastibell rim has fallen off, it indicates that the circumcision site has healed, and the baby is ready to be discharged. The other options, such as the newborn voiding, receiving vitamin K, or yellow exudate forming over the glans, are important aspects of post-circumcision care but are not indicative of the baby being ready for discharge.

Correct Answer: C

Rationale: Herpes zoster, commonly known as shingles, is caused by the reactivation of the varicella-zoster virus, the same virus that causes chickenpox. This virus has an affinity for sensory nerve fibers, particularly those located in the posterior root ganglia and the posterior horn of the spinal cord. When the virus becomes reactivated, it travels along these nerves to the skin, leading to the characteristic painful rash and blisters that are seen in herpes zoster. The involvement of these specific nerve fibers explains the typical dermatomal distribution of the rash in shingles.

Correct Answer: C

Rationale: The symptoms described by the parent, which include inflamed conjunctivae of both eyes with purulent drainage and crusting of the eyelids, are indicative of bacterial conjunctivitis. Bacterial conjunctivitis is typically associated with these symptoms, along with redness, irritation, and a sensation of a foreign body in the eye. It is common for bacterial conjunctivitis symptoms to be most pronounced upon awakening due to the accumulation of discharge overnight. Treatment for bacterial conjunctivitis often involves antibiotic eye drops.
