Correct Answer: B

Rationale: Breastfeeding is the best recommendation to help prevent constipation in infants. Breast milk is easily digestible and contains the right balance of nutrients, which can lead to softer stools, thus reducing the likelihood of constipation. Offering a soy formula (Choice A) may not necessarily prevent constipation as effectively as breast milk due to differences in nutrient composition. Administering a suppository nightly (Choice C) is not a routine measure for preventing constipation in infants and may not be suitable for regular use in this scenario. Offering glucose water (Choice D) between feedings is not recommended as it does not provide the necessary nutrients found in breast milk, which are essential for preventing constipation and promoting overall health in newborns.

Correct Answer: A

Rationale: The priority nursing action after a child has undergone tracheostomy surgery is to suction the tracheostomy tube. Suctioning is crucial to maintain a clear airway, remove secretions, and prevent potential airway obstruction, which is essential for the child's respiratory function. Changing the tracheostomy dressing, while important for wound care, does not take precedence over airway clearance. Monitoring respiratory status is vital but comes after ensuring airway patency. Ensuring tracheostomy ties are secure is significant for stabilizing the tube but is not as urgent as maintaining a patent airway through suctioning.

Correct Answer: B

Rationale: The correct answer is B: Put on gloves because standard precautions are required. Standard precautions, which include wearing gloves, are crucial in preventing the transmission of infections during immunization. Choice A is incorrect because the immediate action should be to address the lack of gloves. Choice C is incorrect as gloves are necessary for infection control. Choice D is incorrect as gloves should be worn as a standard preventive measure, regardless of the child's appearance.

Correct Answer: D

Rationale: A respiratory rate of 50 breaths per minute in a 5-month-old infant is higher than the expected range and may indicate respiratory distress. This finding is concerning and should prompt the nurse to notify the health care provider for further evaluation and intervention. A temperature of 99.5°F, blood pressure of 75/48 mm Hg, and heart rate of 100 beats per minute are within normal ranges for a 5-month-old infant. Elevated temperature may indicate a mild fever, which can be monitored. A blood pressure of 75/48 mm Hg is within the normal range for infants. A heart rate of 100 beats per minute is also within the expected range for a 5-month-old infant and does not typically require immediate notification of the health care provider.

Correct Answer: D

Rationale: Full-thickness burns, also known as third-degree burns, are characterized by a leathery, dry appearance with numbness due to nerve damage. This type of burn extends through all layers of the skin, affecting nerve endings. Choice A describes characteristics of superficial partial-thickness burns, which involve the epidermis and part of the dermis. Choice B describes characteristics of superficial burns, or first-degree burns, which only affect the epidermis. Choice C describes characteristics of superficial to mid-dermal burns, also known as second-degree burns, which involve the epidermis and part of the dermis but do not extend through all skin layers. Therefore, the correct answer is D.
