An infant experienced an apparent life-threatening event (ALTE) and is being placed on home apnea monitoring. Parents have understood the instructions for use of a home apnea monitor when they state?

Correct Answer: C

Rationale: The correct statement indicating understanding of the instructions for use of a home apnea monitor is "We will check the monitor several times a day to be sure the alarm is working." This is important because regular monitoring of the device's functioning ensures that it is able to detect any potential apnea episodes or abnormalities in the infant's breathing patterns. Checking the monitor several times a day helps in maintaining the safety and effectiveness of the monitor in alerting the parents to any potential issues with the infant's breathing. The other options are incorrect: A is incorrect because adjusting the monitor to eliminate false alarms can compromise its accuracy, B is incorrect as the infant should sleep in a separate safe sleep environment to reduce the risk of SIDS, and D is incorrect as the monitor should be placed near the infant's crib but not directly in it for safety reasons.

Correct Answer: C

Rationale: An early clinical manifestation of bilirubin encephalopathy in a newborn is lethargy or irritability. Bilirubin encephalopathy, also known as kernicterus, is a serious condition that occurs when high levels of unconjugated bilirubin build up in the brain tissues. Initially, the baby may become lethargic or irritable due to the toxic effects of bilirubin on the central nervous system. As the condition progresses, symptoms may include poor feeding, high-pitched crying, muscle tone abnormalities, and eventually may lead to more severe consequences such as seizures and irreversible neurological damage. Prompt recognition and treatment of bilirubin encephalopathy are crucial to prevent long-term complications.

Correct Answer: C

Rationale: Adenotonsillar hypertrophy is the leading cause of obstructive sleep apnea in children.

Correct Answer: B

Rationale: The correct option is B - Use a soft toothbrush and electric razor. When a patient is diagnosed with myelocytic leukemia and has bone marrow depression as indicated by laboratory results, the platelet count is usually low which can lead to increased risk of bleeding. Therefore, it is important for the patient to use a soft toothbrush and electric razor to minimize the risk of injury and bleeding. Hard toothbrushes and sharp razors can cause damage to the gums and skin, leading to bleeding complications. It is essential to take precautions to prevent injury and promote safety for the patient undergoing chemotherapy with bone marrow depression.

Correct Answer: B

Rationale: Meningocele is a type of neural tube defect in which there is herniation of the meninges (protective membranes surrounding the brain and spinal cord) through a defect in the spinal column. This results in the formation of a sac-like protrusion that contains the meninges and cerebrospinal fluid but does not involve the spinal cord itself. In meningocele, the spinal cord remains in its normal position within the spinal canal. This condition is typically associated with spina bifida, a neural tube defect that occurs during early embryological development. Unlike myelomeningocele, which involves both the spinal cord and meninges protruding through the spinal column, meningocele specifically refers to the presence of a sac containing the meninges and spinal fluid without direct involvement of the spinal cord.
