The caregiver asks why the 6-month-old infant needs to have solid foods when breast milk is such a good source of nutrition. What would be the best response by the nurse?

Correct Answer: A

Rationale: The correct response is A. Solid foods, especially iron-fortified cereals, are introduced to meet the infant's increased nutritional needs, including iron, which breast milk alone may not provide adequately. Choice B is incorrect because the extrusion reflex is related to the tongue-thrust reflex, not the nutritional needs of the infant. Choice C is incorrect as breastfeeding does not become painful when the infant gets more teeth, and it is not a reason for introducing solid foods. Choice D is incorrect as the infant's interest in trying new skills is not a primary reason for introducing solid foods at this age.

Correct Answer: B

Rationale: The correct intervention to maintain the skin integrity of a preterm infant born at 30 weeks is to bathe the infant with sterile water. Bathing with sterile water or a neutral pH solution is recommended to protect the delicate skin of preterm infants, which is more permeable and prone to damage. Choices A, C, and D are incorrect as avoiding cleaning the skin may lead to hygiene issues, cleansing with alkaline-based soap can be harsh on the delicate skin, and thoroughly rinsing with plain water after bathing may not be as gentle and protective for preterm infants.

Correct Answer: D

Rationale: The correct answer is D. Vaso-occlusive crises in sickle cell anemia require a comprehensive approach that includes adequate hydration to reduce blood viscosity, oxygenation to prevent further sickling of red blood cells, and aggressive pain management. This approach helps improve tissue perfusion and manage pain effectively. Choices A, B, and C are incorrect. Correction of alkalosis is not a priority in vaso-occlusive crisis management. Administration of heparin is not indicated as it can increase the risk of bleeding in sickle cell patients. Factor VIII replacement is not relevant to sickle cell anemia as it is a treatment for hemophilia, not sickle cell disease.

Correct Answer: D

Rationale: The correct order for abdominal examination is inspection, auscult

Correct Answer: B

Rationale: The correct answer is B: 'Observe for projectile vomiting.' Projectile vomiting is a classic sign of pyloric stenosis, caused by obstruction at the pylorus. Choice A is incorrect as metabolic alkalosis, not acidosis, often occurs due to the loss of hydrochloric acid from persistent vomiting. Choice C is incorrect as frequent, small feedings are preferred to prevent overloading the stomach. Choice D is incorrect as placing the infant in an upright position after feeding can help reduce reflux.

Correct Answer: C

Rationale: The correct answer is C: 'The condition is incompatible with life.' Anencephaly is the most serious neural tube defect where both hemispheres of the brain are absent. It is incompatible with life, as there are no medical or surgical treatment options available. While some infants with mature brain stem function can maintain vital functions for a short period, anencephaly is ultimately not survivable. Choice A is incorrect as there are no treatment options for anencephaly. Choice B is incorrect as immediate surgery is not necessary for this condition. Choice D is incorrect as an infant with anencephaly will not have permanent disabilities since the condition is not compatible with life.

Correct Answer: A

Rationale: The correct answer is A: Transition from fetal to neonatal breathing. The most critical physiological change required of newborns at birth is the initiation of breathing. This transition is crucial for the newborn to start exchanging oxygen and carbon dioxide outside the womb, marking the beginning of their independent respiratory function. Choices B, C, and D are important aspects of newborn care but are not as immediately critical as the establishment of breathing for oxygenation and removal of carbon dioxide, which is essential for the newborn's survival and adaptation to extrauterine life.

Correct Answer: D

Rationale: It is essential to use the correct cuff size for accurate blood pressure readings; if the proper size is not available, it's best to wait until it can be obtained.

Correct Answer: D

Rationale: Capillary refill time is assessed by applying pressure to the nail bed and observing how quickly the color returns, indicating peripheral circulation status.
