What should be monitored in a child with congenital adrenal hyperplasia (CAH)?

Correct Answer: B

Rationale: In a child with congenital adrenal hyperplasia (CAH), monitoring electrolyte balance is crucial. CAH can lead to adrenal insufficiency, causing imbalances in electrolytes such as sodium and potassium. Monitoring electrolyte levels helps in preventing complications like dehydration, electrolyte disturbances, and adrenal crisis. While blood glucose levels may need monitoring in other conditions like diabetes, it is not the primary concern in CAH. Urine output is important in assessing kidney function but is not a direct monitoring parameter for CAH. Hemoglobin levels are more relevant in conditions such as anemia, not specifically in CAH.

Correct Answer: D

Rationale: After a bout of diarrhea, it is important to offer foods that are gentle on the stomach and help in recovery. Bananas and rice are commonly recommended as they are easily digestible and can help firm up stools. Apricots, peaches, and applesauce may be too acidic and fibrous, potentially aggravating the stomach. Chocolate milk is high in sugar and can worsen diarrhea due to its lactose content.

Correct Answer: B

Rationale: When a child is newly diagnosed with a hearing impairment, it is essential to refer them for audiologic evaluation and intervention. This step is crucial to accurately assess the extent of the impairment, determine appropriate interventions, and support the child's communication and development. Increasing the volume of all auditory stimuli (choice A) is not a recommended approach as it may not address the specific needs of the child and could potentially cause discomfort. Avoiding the use of assistive devices (choice C) can hinder the child's ability to communicate effectively. Encouraging frequent use of headphones (choice D) is also not advisable as it may not be suitable for managing hearing impairments and could potentially worsen the condition.

Correct Answer: D

Rationale: The correct answer is D, Kilocalorie. The term kilocalorie, often referred to as a calorie, is the amount of heat required to raise the temperature of one kilogram of water by one degree Celsius. While Choice A, Calorie, is technically correct, it is not the most specific term for the described amount of heat. Choice B, Joule, is a unit of energy but not specifically related to the amount of heat required to raise the temperature of water. Choice C, Kilojoule, is also a unit of energy but not the precise term for the heat required to raise the temperature of water by one degree Celsius.

Correct Answer: B

Rationale: When managing a child with a newly diagnosed seizure disorder, it is essential to monitor for triggers and ensure safety. By identifying triggers such as lack of sleep, stress, or specific foods, healthcare professionals can help prevent seizures. Ensuring safety involves creating a safe environment to prevent injuries during a seizure. Choices A, C, and D are incorrect. Avoiding all physical activity can be detrimental as appropriate exercise is essential for overall health. Increasing dietary sodium intake is not a standard recommendation for managing seizures. Restricting all forms of social interaction is unnecessary and can have negative effects on the child's emotional well-being.

Correct Answer: B

Rationale: Observing the nonverbal child's facial expressions and body movements is crucial in assessing pain. Nonverbal children may not be able to communicate their discomfort verbally, making it essential to rely on physical cues. Asking parents about the child's usual behavior (choice A) may provide some insight but observing the child directly is more direct and reliable. Measuring blood pressure (choice C) is not typically a direct method for assessing pain in nonverbal children. Using a pain rating scale designed for older children (choice D) is also inappropriate for nonverbal children who cannot participate in such self-reporting tools.

Correct Answer: C

Rationale: The correct answer is C. An essential nutrient is a substance that is necessary for normal body functioning but cannot be synthesized in adequate amounts by the body, therefore it must be obtained from the diet. Choices A, B, and D are incorrect because essential nutrients are not synthesized by the body, they are necessary for body functioning, and they are not typically stored in the body for long periods.

Correct Answer: C

Rationale: In the scientific method, a hypothesis is a tentative solution or educated guess that is tested through research. A theory (choice A) is a well-substantiated explanation based on evidence and extensive testing. A prediction (choice B) is a statement about what will happen in the future based on existing knowledge. Correlation (choice D) refers to a mutual relationship between two or more things, indicating how they may change together but not providing a solution to a problem.

Correct Answer: A

Rationale: The correct answer is fats. Fats provide 9 kilocalories per gram, which is more energy-dense compared to proteins and carbohydrates. While proteins and carbohydrates provide 4 kilocalories per gram, fats provide more than twice the energy, making them the most energy-providing nutrient. Alcohols are not considered essential nutrients and do not provide energy for the body, unlike fats, proteins, and carbohydrates. Therefore, fats are the correct answer for the most energy-providing nutrient.
