When assessing a newborn, which is the best method for the nurse to use to elicit the Moro reflex?

Making a loud sound within close range of the newborn.

Firmly stroking the soles of the newborn’s feet with a thumb nail.

Using the newborn’s hands to raise the baby from a supine position without supporting the head.

Holding the newborn in an upright position so that the infant’s feet touch a cool, flat surface.

Answer and Explanation

The Correct Answer is A

The correct answer is choice A. Making a loud sound within close range of the newborn will elicit the Moro reflex, which is an involuntary protective motor response against abrupt disruption of body balance or extremely sudden stimulation. The Moro reflex involves three distinct components: spreading out the arms (abduction), pulling the arms in (adduction), and crying (usually).

Choice B is wrong because firmly stroking the soles of the newborn’s feet with a thumb nail will elicit the Babinski reflex, which is a normal response in infants that involves fanning out and curling of the toes.

Choice C is wrong because using the newborn’s hands to raise the baby from a supine position without supporting the head will elicit the traction response, which is a normal response in infants that involves flexion of the elbows and shoulders.

Choice D is wrong because holding the newborn in an upright position so that the infant’s feet touch a cool, flat surface will elicit the stepping reflex, which is a normal response in infants that involves alternating steps with each foot.

Correct Answer is D

Explanation

he correct answer is choice D. Keep the infant well hydrated.This is because phototherapy can cause dehydration due to increased insensible water loss from the skin.Hydration helps the infant excrete bilirubin in urine and stool.

Choice A is wrong because elevating the head of the infant’s crib does not affect bilirubin levels or phototherapy effectiveness.

Choice B is wrong because applying a water-soluble ointment to the infant’s eyes can interfere with eye protection and cause eye irritation.The infant’s eyes should be covered with opaque patches or goggles during phototherapy to prevent eye damage.

Choice C is wrong because dressing the infant in a long-sleeved shirt reduces the amount of skin exposed to light and decreases the efficacy of phototherapy.The infant should be undressed except for a diaper and eye protection during phototherapy.

Normal ranges for bilirubin levels vary depending on the age of the infant, the type of jaundice, and the method of measurement.Generally, bilirubin levels above 25 mg/dL are considered dangerous and require urgent treatment.

A. Herpes simplex II. B. Syphilis. C. Gonorrhea. D. Condylomata.

Correct Answer is B

Explanation

The correct answer is choice B. Syphilis.A negative rapid plasma reagin (RPR) test indicates that a patient is probably not infected with syphilis, a sexually transmitted infection (STI) caused by the bacterium Treponema pallidum.The RPR test works by detecting the nonspecific antibodies that your body produces while fighting the infection.

Choice A is wrong because herpes simplex II is a viral infection that causes genital herpes, and it is not detected by the RPR test.

Choice C is wrong because gonorrhea is a bacterial infection caused by Neisseria gonorrhoeae, and it is also not detected by the RPR test.

Choice D is wrong because condylomata are genital warts caused by human papillomavirus (HPV), and they are not detected by the RPR test either.

The RPR test is a screening test, and it can give false-positive results due to other conditions or infections.Therefore, a positive RPR test should always be confirmed by a more specific treponemal test, such as TPPA or FTA-ABS.The RPR test can also be used to monitor the treatment response of syphilis, as the antibody levels should decrease after effective antibiotic therapy.
