Correct Answer: B

Rationale: Assessing hydration status is crucial in an infant who is vomiting frequently, as dehydration can quickly become a serious issue. In this scenario, the infant's inability to retain feeds and lack of weight gain may indicate a potential risk of dehydration, making it essential to prioritize checking the infant's hydration status to prevent complications. Evaluating the feeding technique (Choice A) could be important but is secondary to addressing potential dehydration. Measuring the abdominal circumference (Choice C) and reviewing the growth chart (Choice D) are not the priority in this situation where dehydration is a primary concern.

Correct Answer: D

Rationale: The correct answer is D. Wearing long sleeves and pants is an effective measure to prevent tick bites, which can transmit Lyme disease. Ticks are commonly found in wooded areas and tall grass, so covering exposed skin helps reduce the risk of tick bites and subsequently lowers the risk of contracting Lyme disease. Choices A, B, and C do not directly address the mode of transmission of Lyme disease. Option A pertains to respiratory protection against dust, Option B focuses on wound care, and Option C relates to water safety, none of which are directly related to preventing Lyme disease transmission.

Correct Answer: B

Rationale: The correct answer is to notify the healthcare provider immediately. The child's presentation of sudden, severe abdominal pain in the lower right abdomen is highly concerning for appendicitis, a medical emergency. Promptly notifying the healthcare provider is crucial for further evaluation and management. Administering pain medication as the first action might mask symptoms and delay diagnosis. Starting an IV line for fluid administration and obtaining a complete blood count are important interventions but should come after healthcare provider notification.

Correct Answer: B

Rationale: The correct priority action for the nurse is to start an IV infusion of normal saline. The client's presentation with lethargy, fruity-smelling breath, and high blood glucose level indicates diabetic ketoacidosis (DKA). IV fluids are essential to correct dehydration and help stabilize the client's condition. Checking for ketones in the urine is important, but fluid replacement takes precedence to address the immediate risk of dehydration and electrolyte imbalances. Administering insulin is also a crucial intervention for DKA, but fluid resuscitation should first be initiated.

Correct Answer: B

Rationale: Thickening formula with cereal is a recommended intervention for infants with gastroesophageal reflux disease (GERD) to help reduce vomiting and increase caloric intake. This modification can help the infant keep the food down better, reducing reflux symptoms while providing adequate nutrition. Giving small amounts of baby food with each feeding (Choice A) is not recommended for a 5-month-old with GERD as it may exacerbate symptoms. Diluting the child's formula with equal parts of water (Choice C) can lead to inadequate nutrition and is not advisable. Offering 10% dextrose in water between most feedings (Choice D) is not appropriate for managing GERD in infants and does not address the underlying issue of reflux.
