The MOST common behavioral sleep disorder in a 4-month-old baby who needs to be rocked to sleep is

Correct Answer: D

Rationale: The correct answer is D) sleep-onset association disorder. This sleep disorder is characterized by a baby needing a specific condition or action, such as being rocked, to fall asleep. In this case, the baby has associated rocking with falling asleep, making it difficult for them to self-soothe and fall asleep independently. This dependency on external stimuli for sleep onset can disrupt the baby's sleep patterns and cause sleep disturbances. Option A) early signs of ADHD is incorrect because the behavior described does not align with the symptoms of ADHD in infants. Option B) primary restless legs syndrome is incorrect as it typically presents with uncomfortable sensations in the legs and an urge to move them, not related to needing to be rocked to sleep. Option C) sleep terrors are also unrelated to the scenario described in the question. In an educational context, understanding common sleep disorders in infants is crucial for pediatric nurses. Recognizing sleep-onset association disorder allows nurses to provide appropriate guidance to parents on sleep training techniques to help the baby develop healthy sleep habits. Educating parents on creating a conducive sleep environment and promoting self-soothing skills can be beneficial in managing this disorder and promoting better sleep for the infant.

Correct Answer: E

Rationale: In this question from the Certified Pediatric Nurse Exam Practice Questions, the correct answer is E, which is not listed among the given options. Let's analyze the options provided: A) Rattlesnake envenomations: Antivenin is indicated for the treatment of rattlesnake envenomations as it helps neutralize the toxins injected by the snake. B) Scorpion envenomations: Antivenin is also used in the treatment of scorpion envenomations to counteract the effects of the venom. C) Black widow envenomations: Antivenin is considered in the treatment of black widow envenomations to manage the symptoms caused by the spider bite. D) Stonefish envenomations: Antivenin is used for the treatment of stonefish envenomations as well, as it helps in reversing the toxic effects of the venom. The correct answer, E, would likely be an option not commonly treated with antivenin in the context of pediatric nursing. In an educational context, understanding the specific indications for antivenin use in different types of envenomations is crucial for pediatric nurses to provide effective and timely care to pediatric patients who have been exposed to venomous bites or stings. This knowledge helps in ensuring appropriate treatment interventions are initiated promptly to improve patient outcomes.

Correct Answer: B

Rationale: The correct answer is B) colic. Colic is a common condition in infants under 3 months old, characterized by excessive crying and fussiness, often worse in the evening. This can disrupt sleep patterns, leading to sleeping difficulties in the first 2 months of life. Colic is not a serious medical condition but can be distressing for both the baby and the parents. Option A) gastro-esophageal reflux can also cause sleeping difficulties in infants, but it is less common in the first 2 months of life compared to colic. Reflux is more commonly seen around 4-6 months of age. Option C) formula intolerance can lead to digestive issues such as gas, bloating, and discomfort, but it is less likely to be the most common cause of sleeping difficulty in the first 2 months of life compared to colic. Option D) developmentally self-resolving sleeping behavior refers to normal changes in infants' sleep patterns as they grow and develop. While this can cause some variations in sleep, it is not the most common cause of sleeping difficulty in the first 2 months of life. Educationally, it is important for pediatric nurses to understand the common causes of sleeping difficulties in infants to provide appropriate care and support to both the baby and the parents. Recognizing and addressing issues like colic can help improve the overall well-being of the infant and promote better sleep patterns for the whole family.

Correct Answer: B

Rationale: In this question, the correct answer is B) 3 months. At around 3 months of age, infants typically achieve early head control with a bobbing motion when pulled to sit. This milestone is an important indicator of the infant's developing neck and upper body strength, which are crucial for future motor skills and developmental milestones. Option A) 2 months is incorrect because at this age, infants are still developing their head control and are not typically able to exhibit the described bobbing motion when pulled to sit. Option C) 4 months is incorrect because by this age, infants should have already achieved early head control and be able to demonstrate the bobbing motion when pulled to sit. Option D) 6 months is incorrect as infants should have developed more advanced head and neck control by this age, surpassing the early head control stage described in the question. Understanding these developmental milestones is crucial for pediatric nurses as it helps them monitor and assess the growth and development of infants accurately. Recognizing these milestones can also aid in early identification of any potential developmental delays, allowing for timely interventions and support for the infant and their family.

Correct Answer: B

Rationale: The correct answer is B) molar at 6 years. The first permanent tooth to erupt in a child is typically the first molar, which usually appears around the age of 6. This is considered a landmark event in a child's dental development. Central incisors typically erupt around 6-7 years of age, not as the first permanent tooth. Premolars and canines generally erupt later in the mixed dentition stage, not as the first permanent tooth. Upper canines typically erupt around 9-10 years of age, again not as the first permanent tooth. Understanding the sequence of tooth eruption is crucial for pediatric nurses as they play a vital role in educating children and parents about dental health. Knowing the typical age range for the eruption of different teeth helps in monitoring children's dental growth and identifying any potential issues early on. This knowledge allows for early intervention and preventive care to promote optimal oral health in children.
