A pediatrician has prescribed oxygen as needed for an infant with heart failure. Which situation would likely increase the oxygen demand. requiring the nurse to administer oxygen to the infant?
when a parent is holding the infant
During sleep
When changing the infant's diapers
When drawing blood for electrolyte level testing
The Correct Answer is D
A. When a parent is holding the infant
Explanation: Being held by a parent is generally a comforting and calming experience for an infant, and it is unlikely to significantly increase oxygen demand. In fact, the presence of a familiar caregiver may help reduce stress.
B. During sleep
Explanation: During sleep, an infant's oxygen demand may decrease, and oxygen supplementation may not be necessary unless there are specific indications or concerns about oxygen saturation levels.
C. When changing the infant's diapers
Explanation: Changing a diaper is a routine care activity that is not likely to significantly increase oxygen demand. It is not typically associated with stress or increased metabolic activity that would necessitate additional oxygen.
D. When drawing blood for electrolyte level testing
Explanation:
Drawing blood for electrolyte level testing is a potentially stressful procedure that may cause distress and anxiety in the infant. Stress and anxiety can increase the metabolic rate and oxygen demand. In a situation where an infant is already prescribed oxygen as needed for heart failure, additional stressors like blood drawing may necessitate the administration of oxygen to ensure an adequate oxygen supply

Correct Answer is B
Explanation
A. "I will limit my child's fluid intake."
Incorrect: Limiting fluid intake is not typically recommended for children with CF. Maintaining hydration is important, especially since individuals with CF may have increased salt losses in sweat.
B. "We will give our child pancreatic enzymes with snacks and meals."
Correct Answer: This response indicates an understanding of the importance of giving pancreatic enzymes to assist with digestion, as individuals with CF often have pancreatic insufficiency. Pancreatic enzymes help in the absorption of nutrients from food.
C. "We will restrict the amount of salt in our child's food."
Incorrect: While it's true that individuals with CF may need to increase their salt intake due to increased salt losses in sweat, this response suggests restricting salt, which is not in line with the nutritional needs of a child with CF.
D. "I will prepare low-fat meals with limited protein for my child."
Incorrect: Children with CF often need a higher calorie intake, including healthy fats and adequate protein. Restricting fat and protein is not in line with the nutritional needs of a child with CF.
Correct Answer is D
Explanation
A. 1 cup cooked rice: This exceeds the 1 oz serving size and is more than what the nurse is recommending.
B. Flour tortilla: The size of a flour tortilla can vary, but it often exceeds the 1 oz serving size, so it may provide more than the recommended amount.
C. 1 cup ready-to-eat cereal flakes: The volume of cereal can vary, and 1 cup of cereal may provide more than 1 oz of grains, depending on the type and density of the cereal.
D. 1 slice whole wheat bread: A standard slice of whole wheat bread typically provides around 1 oz of grains, making it an appropriate choice for the recommended serving size.
