Which one of the following statements is correct with regards to face presentation?

Correct Answer: C

Rationale: The correct answer is C: Majority are classified as secondary face presentation. In face presentation, the fetal head is hyperextended, presenting the face to the birth canal. Primary face presentation is rare. The bi-parietal diameter is not the presenting diameter in face presentation, as it is in vertex presentation. Locating the anterior fontanelle is not diagnostic of face presentation, as the fontanelles can be difficult to palpate during labor. Therefore, the correct statement is that the majority of face presentations are classified as secondary face presentation.

Correct Answer: C

Rationale: The presenting diameter in brow presentation is the suboccipitofrontal diameter. This is because in brow presentation, the fetal head is in a deflexed position, with the largest diameter being from the subocciput (back of the head) to the frontal bone (forehead). This allows the head to enter the pelvis in the transverse diameter. A: Mentovertical - This refers to the chin to the top of the head, not the correct diameter for brow presentation. B: Submentobregmatic - This refers to the chin to the bregma, not the correct diameter for brow presentation. D: Occipitalfrontal - This refers to the back of the head to the forehead, not the correct diameter for brow presentation.

Correct Answer: D

Rationale: The correct answer is D: Check the neonate’s vital signs every 2-4 hourly. This is the priority action because neonates undergoing phototherapy are at risk for dehydration and temperature instability. Monitoring vital signs regularly helps to detect any signs of dehydration, such as decreased urine output or increased heart rate, and ensures timely intervention. Explanation for other choices: A: Turning the neonate every six hours routinely is important for preventing pressure ulcers but is not the priority when compared to monitoring vital signs for potential complications. B: Encouraging the mother to discontinue breastfeeding is incorrect as breastmilk provides essential nutrients and hydration, which are important for neonates, even during phototherapy. C: Notifying the physician if the skin turns bronze-colored is important to address a potential adverse reaction to phototherapy but does not take precedence over monitoring vital signs for immediate concerns.

Correct Answer: A

Rationale: The correct answer is A: Six hours postnatally. Cephalohematoma is a collection of blood between a baby's skull and the periosteum. It typically appears several hours after birth due to trauma during delivery, causing bleeding under the periosteum. This allows time for the blood to accumulate and form a distinct swelling, making the onset around six hours postnatally. Choices B, C, and D are incorrect as they do not align with the typical timeline for the development of cephalohematoma.

Correct Answer: D

Rationale: Non-infective mastitis is associated with adenitis because it refers to inflammation of breast tissue without an infection. Adenitis specifically involves inflammation of the lymph nodes, which can be a common cause of non-infective mastitis. Cellulitis (A) is an infection of the skin and tissues beneath the skin, not specific to mastitis. Flat (B) and bifid (C) nipples are anatomical variations that do not directly relate to the inflammation of breast tissue.
