Which is the most critical physiologic change required of the newborn?

  • A. Closure of fetal shunts in the heart
  • B. Stabilization of fluid and electrolytes
  • C. Body-temperature maintenance
  • D. Onset of breathing
Correct Answer: D

Rationale: The most critical physiologic change required of the newborn is the onset of breathing. Prior to birth, the fetus receives oxygen from the mother's blood through the placenta. However, once the newborn is delivered, it needs to begin breathing on its own to support oxygen exchange and remove carbon dioxide from the body. The respiratory system must transition from a fluid-filled state in the womb to an air-filled state outside the womb. The onset of breathing is essential for the newborn's survival and initiates the process of oxygenation of tissues and removal of carbon dioxide, which are vital for metabolism and overall physiological functioning. While closure of fetal shunts, stabilization of fluid and electrolytes, and body-temperature maintenance are also important changes that occur in the newborn, the onset of breathing is the most critical to ensure proper oxygenation of the body's tissues.

A neonate has been diagnosed with caput succedaneum. Which statement is correct about this condition?

  • A. It usually resolves in 3-6 weeks
  • B. It doesn't cross the cranial suture line
  • C. It's a collection of blood between the skull and the periosteum
  • D. It involves swelling of tissue over the presenting part of the presenting head
Correct Answer: D

Rationale: Caput succedaneum is a condition characterized by the swelling of tissue over the presenting part of the infant's head during delivery. It is commonly a result of prolonged labor or vacuum extraction. Unlike cephalohematoma, caput succedaneum does cross the cranial suture lines. This condition typically resolves within a few days to a week after birth without intervention. It is important to monitor the infant for any complications or signs of infection during the resolution process.

What is the causative agent in HIV/AIDS?

  • A. trichomonas vaginalis
  • B. Treponema pallidum
  • C. Human, T-cell lymphotrophio virus
  • D. Chlamydia tranchomatis
Correct Answer: C

Rationale: The causative agent of HIV/AIDS is the Human Immunodeficiency Virus (HIV). HIV infects and kills the immune system's CD4 T cells, weakening the immune system and making the body more susceptible to infections and certain cancers. The virus is primarily transmitted through sexual contact, exposure to infected blood, sharing needles, and from mother to child during childbirth or breastfeeding. Trichomonas vaginalis, Treponema pallidum, and Chlamydia trachomatis are all different microorganisms that are not responsible for causing HIV/AIDS.

Low birth weight or premature infants are screened for anemia at birth and again at the age of

  • A. 2 months
  • B. 4 months
  • C. 6 months
  • D. 8 months
Correct Answer: C

Rationale: Anemia screening for low birth weight or premature infants is recommended at 6 months.

What are distended sebaceous glands that appear as tiny white papules on cheeks, chin, and nose in the newborn period called?

  • A. Milia
  • B. Lanugo
  • C. Mongolian spots
  • D. Cutis marmorata
Correct Answer: A

Rationale: Milia are distended sebaceous glands that appear as tiny white papules on the cheeks, chin, and nose in the newborn period. They are commonly found in newborns and usually resolve on their own without treatment. Milia are not harmful and are considered a normal physiological occurrence in newborns. Lanugo refers to fine, downy hair covering newborn infants, Mongolian spots are blue-grey birthmarks usually found on the lower back or buttocks of newborns, and Cutis marmorata is a vascular mottling of the skin in newborns.

A patient is scheduled for an MRI and asks what to expect. Which of the following responses by the nurse is best?

  • A. "It is the measurement of muscle contraction after stimulation by tiny needle electrodes."
  • B. "Electrodes will be placed on your scalp to measure activity of the brain."
  • C. "A scan of the brain will be done after injection of radioisotope."
  • D. "It is a noninvasive test that uses magnetic energy to visualize internal parts."
Correct Answer: D

Rationale: The best response by the nurse in this scenario is option D: "It is a noninvasive test that uses magnetic energy to visualize internal parts." This response provides a clear and accurate description of what an MRI (Magnetic Resonance Imaging) involves. An MRI is a diagnostic test that uses a powerful magnetic field, radio waves, and a computer to create detailed images of the internal structures of the body. It is noninvasive, meaning there are no needles, electrodes, or injections involved. By explaining the procedure in a simple and understandable way, the nurse can help alleviate any anxiety or concerns the patient may have about the upcoming MRI.
