The nurse is caring for a 3-year-old child who has been recently diagnosed with cystic fibrosis. Which discharge instruction by the nurse is most important to promote pulmonary function?

A. Chest physiotherapy should be performed before meals and at bedtime

B. Cough suppressants can be used up to four times a day for relief

C. Oxygen should be given through a nasal cannula between 4-6 L/min

D. Exercise is discouraged in order to preserve pulmonary vital capacity

Correct Answer: B
Rationale: In cystic fibrosis, thick mucus obstructs the airways, making it difficult to clear from the lungs. Cough suppressants can help reduce the discomfort associated with persistent coughing, allowing the child to cough more effectively to clear the mucus, thus promoting pulmonary function. Chest physiotherapy, not exercise, helps mobilize the mucus. Oxygen therapy may be needed but is not the most important for promoting pulmonary function in this case.

Which nursing intervention is most important to assist in detecting hypopituitarism and hyperpituitarism in children?

• A. Carefully recording the height and weight of children to detect inappropriate growth.
• B. Performing head circumference measurements on infants under one year of age.
• C. Assessing for behavioral problems at home and school by interviewing the parents.
• D. Noting tracked weight gain without a gain in height on a growth chart.

Correct Answer: A
Rationale: Recording the height and weight of children is crucial in detecting growth abnormalities like hypopituitarism and hyperpituitarism. Inappropriate growth patterns, such as disproportionate weight gain or stunted height, can be indicative of these conditions. Regular monitoring of height and weight is a fundamental nursing intervention that can aid in the early identification and management of pituitary-related disorders in children.

In a 7-year-old child with a history of asthma experiencing an acute asthma exacerbation and displaying wheezing and the use of accessory muscles to breathe, what is the nurse’s priority intervention?

• A. Administer a nebulized bronchodilator
• B. Obtain an arterial blood gas
• C. Start the child on oxygen therapy
• D. Notify the healthcare provider

Correct Answer: A
Rationale: The correct answer is to administer a nebulized bronchodilator. During an acute asthma exacerbation in a child with wheezing and increased work of breathing, the priority intervention is to provide immediate bronchodilation to dilate the airways, relieve bronchospasm, and improve breathing. This intervention aims to manage the acute asthma attack effectively and prevent further respiratory distress. Obtaining an arterial blood gas, starting oxygen therapy, or notifying the healthcare provider are important actions, but administering a bronchodilator takes precedence in addressing the acute respiratory compromise.

A 10-year-old child is admitted with diabetic ketoacidosis (DKA). Which laboratory value should the practical nurse (PN) anticipate?

• A. Elevated blood glucose.
• B. Decreased serum ketones.
• C. Low urine glucose.
• D. High bicarbonate levels.

Correct Answer: A
Rationale: In a case of diabetic ketoacidosis (DKA), the primary feature is elevated blood glucose levels due to insulin deficiency. Additionally, ketones are increased in the blood and urine. Bicarbonate levels are usually low because of the metabolic acidosis that accompanies DKA. Therefore, the practical nurse should anticipate elevated blood glucose levels as a characteristic laboratory finding in a child admitted with DKA. Choice B is incorrect because serum ketones are increased in DKA. Choice C is incorrect because in DKA, urine glucose is typically high due to spillage of glucose into the urine. Choice D is incorrect because bicarbonate levels are usually low in DKA, not high.

The caregiver discovers a 6-month-old infant unresponsive and calls for help. After opening the airway and finding the infant is still not breathing, what action should the caregiver take?

• A. Palpate femoral pulse and check for regularity.
• B. Deliver cycles of 30 chest compressions and 2 breaths.
• C. Give two breaths that make the chest rise.
• D. Feel the carotid pulse and check for adequate breathing.

Correct Answer: C
Rationale: Providing two breaths that make the chest rise is the correct action in this situation. This helps to deliver oxygen to the infant's lungs and body, which is crucial in a situation where the infant is not breathing. Chest rise indicates successful ventilation, and it is an essential step in pediatric resuscitation, especially for infants. Choices A, B, and D are incorrect because palpating the femoral pulse, delivering chest compressions, and feeling the carotid pulse are not the initial actions to take when an infant is not breathing. The priority is to provide effective breaths to establish ventilation.
