A nurse is caring for a child with a history of frequent ear infections. The nurse should educate the parents about the importance of keeping the child's ears

Correct Answer: A

Rationale: Educational Rationale: The correct answer is A) Clean and dry. This is because moisture and dirt in the ears can create a breeding ground for bacteria, leading to ear infections. By keeping the child's ears clean and dry, the risk of developing infections is reduced. Educating parents on proper ear hygiene practices is crucial in preventing recurrent ear infections in children with a history of such issues. Option B) Covered with earplugs when swimming is incorrect because while it is important to prevent water from entering the ears during swimming to avoid swimmer's ear, covering the ears with earplugs all the time can also trap moisture and lead to infections. Option C) Rinsed with a vinegar solution is incorrect as this practice is not recommended for routine ear care in children. While vinegar can be used in specific cases under healthcare provider guidance, it is not a general preventive measure for ear infections. Option D) Exposed to cold air to prevent infection is incorrect as exposing the ears to cold air does not prevent ear infections. In fact, sudden exposure to cold air can sometimes cause discomfort and may not be beneficial in preventing infections. In an educational context, it is essential for nurses to provide parents with accurate information and guidance on how to maintain good ear hygiene practices for their children. By explaining the rationale behind the correct answer and debunking misconceptions related to other options, nurses can empower parents to take proactive measures in preventing ear infections in their children.

Correct Answer: D

Rationale: The correct answer is D) Increasing fluid intake to prevent dehydration. When caring for a child with a respiratory infection, maintaining adequate hydration is crucial for thinning respiratory secretions, promoting airway clearance, and preventing dehydration due to increased respiratory effort and fever. Dehydration can worsen respiratory symptoms and compromise overall health. Option A, encouraging a high-protein diet, is not the priority as hydration takes precedence in this situation. Option B, providing a cool mist humidifier, can be beneficial for easing breathing but does not address the immediate need for hydration. Option C, administering antipyretics for fever, is important but should not take precedence over ensuring adequate hydration. In an educational context, it is essential for nursing students preparing for the NCLEX to understand the priority of interventions in pediatric respiratory infections. Recognizing the significance of maintaining hydration in these cases can prevent complications and promote effective nursing care. Remembering the physiological impact of dehydration on respiratory function can guide nurses in prioritizing care for pediatric patients with respiratory infections.

Correct Answer: D

Rationale: In pediatric respiratory development, understanding the different phases of lung development is crucial. The correct answer to this question is D) Canalicular phase. During the canalicular phase, which typically occurs between weeks 16 to 26 of gestation, the lung undergoes significant growth and differentiation. One of the key characteristics of this phase is the formation of a capillary network around the developing airway passages. This capillary network is essential for the exchange of gases, allowing for oxygen to be absorbed and carbon dioxide to be released. Now, let's discuss why the other options are incorrect: A) Pseudoglandular phase: This phase occurs earlier in lung development and is characterized by the branching of the conducting airways, but not specifically by the formation of a capillary network around airway passages. B) Saccular phase: In this phase, the primitive air sacs called saccules start to form, but again, it does not involve the development of a capillary network around airway passages. C) Alveolar phase: This phase occurs later in lung development and is characterized by the formation of mature alveoli. While gas exchange occurs in the alveoli, the specific formation of a capillary network around airway passages is not a defining feature of this phase. Understanding the different phases of lung development is essential for pediatric nurses as it provides insights into potential respiratory complications that may arise in premature infants or infants with respiratory disorders. By knowing the specific characteristics of each phase, nurses can better anticipate and manage respiratory issues in pediatric patients.

Correct Answer: B

Rationale: Wharton's jelly is a gelatinous substance found inside the umbilical cord that plays a crucial role in supporting the cord's structure and function. The correct answer, option B, "To prevent the vessels inside the cord from kinking," is accurate because Wharton's jelly acts as a cushion to protect the blood vessels (arteries and veins) within the umbilical cord. By maintaining the patency of these vessels, Wharton's jelly ensures a continuous flow of oxygen and nutrients from the placenta to the developing fetus and facilitates the removal of waste products from the fetus. Option A, "To help provide nutrition to the fetus," is incorrect because the primary role of the umbilical cord is to transport nutrients, not to provide them. The mother's placenta is responsible for transferring nutrients to the fetus, while the umbilical cord serves as the conduit for this exchange. Option C, "To help protect the fetus," while partially true due to the supportive role of Wharton's jelly in maintaining cord integrity, is not the primary function of this substance. Protection of the fetus is more related to the amniotic fluid and the physical barriers surrounding the fetus in the womb. Option D, "To regulate the temperature between the fetus and the mother," is also incorrect as the regulation of temperature is mainly controlled by the mother's body and the amniotic fluid, not by Wharton's jelly within the umbilical cord. Understanding the function of Wharton's jelly is important in the context of pediatric nursing and obstetrics as it relates to fetal development, circulation, and overall well-being. Nurses need to comprehend how structures like the umbilical cord work to provide optimal care for both the fetus and the mother during pregnancy and childbirth.

Correct Answer: A

Rationale: The correct answer is A) Group B Streptococcus. Group B Streptococcus (GBS) is a common bacterium that can colonize the genital tract of pregnant women and can lead to various complications during pregnancy, including preterm birth, chorioamnionitis, and neonatal sepsis. Screening for GBS during pregnancy and administering antibiotics during labor can help prevent adverse outcomes for both the mother and the newborn. Option B) Haemophilus influenzae is not typically associated with affecting pregnancy outcomes. Haemophilus influenzae commonly causes respiratory infections in children, such as pneumonia and otitis media. Option C) Mycobacterium tuberculosis is the bacterium that causes tuberculosis, a respiratory infection that can affect individuals of all ages but is not specifically known to impact pregnancy outcomes. Option D) Hepatitis C virus is a bloodborne virus that primarily affects the liver and is not directly linked to affecting pregnancy outcomes, although it can be transmitted from mother to baby during childbirth. Understanding the impact of different microorganisms on pregnancy outcomes is crucial for healthcare providers, especially those working in obstetrics and pediatrics. Proper screening, early detection, and appropriate management strategies can significantly improve maternal and neonatal health outcomes. Healthcare professionals need to be well-versed in recognizing the implications of various infections during pregnancy to provide optimal care for expectant mothers and their babies.
