Which statement by a school-aged client going to summer camp indicates the best understanding of the mode of transmission of Lyme disease?

A. I'll cover my mouth with a wet cloth if there's too much dust blowing.

B. Cuts and scrapes need to be washed out and covered right away.

C. I'm not going to swim where the water is standing still or feels too hot.

D. I have to wear long sleeves and pants when we're hiking around the pond.

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.

A 7-year-old child with cystic fibrosis is admitted to the hospital with a respiratory infection. The nurse is teaching the child’s parents about the importance of chest physiotherapy (CPT). Which statement by the parents indicates they need further teaching?

• A. We should perform CPT before meals.
• B. CPT will help loosen mucus in the lungs.
• C. We should perform CPT right after the child eats.
• D. CPT is an important part of our child’s treatment.

Correct Answer: C
Rationale: The correct answer is C. Chest physiotherapy should not be performed right after meals to avoid inducing vomiting. It should be done before meals or at least 1 hour after for effective mucus clearance and to prevent any potential complications like vomiting. Choice A is correct as performing CPT before meals helps in loosening mucus. Choice B is also correct as CPT is indeed helpful in loosening mucus in the lungs. Choice D is correct as CPT plays a crucial role in the treatment of cystic fibrosis.

What is the priority intervention for a 16-year-old client with a history of depression who is brought to the emergency department after taking an overdose of acetaminophen?

• A. Administer activated charcoal
• B. Place the client on continuous cardiac monitoring
• C. Prepare for gastric lavage
• D. Administer N-acetylcysteine as prescribed

Correct Answer: D
Rationale: The priority intervention for a client who has taken an acetaminophen overdose is to administer N-acetylcysteine promptly. N-acetylcysteine is the antidote for acetaminophen overdose and helps prevent liver damage. Activated charcoal may be used in certain cases, but N-acetylcysteine takes precedence as it directly counteracts the toxic effects of acetaminophen. Continuous cardiac monitoring and gastric lavage are not the priority interventions for acetaminophen overdose. Administering N-acetylcysteine is crucial to prevent liver damage and address the overdose, making it the most urgent action in this scenario.

The caregiver is caring for a 3-year-old child with a diagnosis of gastroenteritis. The child has had several episodes of vomiting and diarrhea over the past 24 hours. What is the caregiver's priority assessment?

• A. Monitor the child's weight
• B. Assess the child's hydration status
• C. Evaluate the child's nutritional intake
• D. Check the child's temperature

Correct Answer: B
Rationale: The correct answer is B: Assess the child's hydration status. In children with gastroenteritis, assessing hydration status is crucial as they are at risk of dehydration due to vomiting and diarrhea. Monitoring hydration helps prevent complications and guides appropriate interventions to maintain the child's fluid balance. Monitoring the child's weight (Choice A) is not the priority in this situation compared to assessing hydration status. Evaluating nutritional intake (Choice C) is important but not the priority when the child is at risk of dehydration. Checking the child's temperature (Choice D) is relevant but not the priority over assessing hydration status in a child with gastroenteritis.

The child is 3 years old and is 2 hours postop from a cardiac catheterization via the right femoral artery. Which assessment finding indicates arterial obstruction?

• A. Blood pressure is decreasing, and the pulse is rapid and irregular.
• B. The right foot feels cool to the touch and appears pale and blanched.
• C. The pulse distal to the femoral artery is weaker in the left foot than the right foot.
• D. The pressure dressing at the right femoral area is damp and oozing blood.

Correct Answer: B
Rationale: A cool, pale, and blanched foot is indicative of arterial obstruction, leading to poor blood flow. This finding requires immediate intervention to prevent further complications such as tissue damage or necrosis. Monitoring for signs of arterial compromise, such as color changes, temperature, and capillary refill, is crucial in detecting and managing vascular complications post-cardiac catheterization. Choices A, C, and D do not directly indicate arterial obstruction. While a decreasing blood pressure and rapid, irregular pulse may suggest compromise, these findings are more nonspecific. A weaker pulse distal to the femoral artery indicates reduced perfusion but not necessarily arterial obstruction. Finally, a damp, oozing pressure dressing suggests a dressing issue rather than arterial obstruction.
