A school nurse identifies that a child has pediculosis capitis (head lice) and educates the child's parents about the condition. Which of the following statements by the parents indicates an understanding of the teaching?
"My child must be free from nits before returning to school.”
"Toys that can't be dry cleaned or washed must be thrown out.”
"I will treat all the family members to be on the safe side.”
"All recently used clothing, bedding, and towels must be washed in hot water.”
The Correct Answer is D
Choice A rationale:
Requiring the child to be free from nits before returning to school might not be an accurate understanding of the situation. Nits are the eggs of head lice and may remain attached to the hair even after effective treatment. The presence of live lice is a more crucial factor to consider.
Choice B rationale:
Throwing out toys that can't be dry cleaned or washed is an unnecessary and extreme measure. Head lice do not survive long away from the human scalp, so the risk of transmission through inanimate objects like toys is minimal. Thoroughly cleaning and vacuuming the environment is more effective.
Choice C rationale:
Treating all family members is indeed a prudent approach. Head lice can spread easily within households, especially among close contacts. Treating everyone helps prevent re-infestation and disrupts the lice life cycle.
Choice D rationale:
Washing recently used clothing, bedding, and towels in hot water is a correct understanding of how to manage head lice. The high temperature kills lice and their eggs. It is an essential step in preventing the spread of lice and re-infestation.

Correct Answer is C
Explanation
A. The left fifth intercostal space at the midclavicular line is the location for palpating the apical pulse, not the pulmonic area. This area is used to assess the heart's apex, particularly for detecting the point of maximal impulse (PMI).
B. The left fifth intercostal space is also associated with the apical pulse, but it lacks the specificity of the midclavicular line, making it less precise for identifying the pulmonic area.
C. The left second intercostal space is the correct location for palpating the pulmonic area. This area is where the pulmonic valve is best auscultated and palpated, allowing for the detection of any abnormal pulsations or sounds related to the pulmonary artery.
D. The right second intercostal space is the location for palpating the aortic area, not the pulmonic area. This site is used to assess the aortic valve and any related abnormalities.
Correct Answer is B
Explanation
Choice A rationale:
Auscultation at the pulmonic and mitral points would not provide the clearest hearing of the S2 heart sound. The S2 sound is composed of two components: A2 (aortic valve closure) and P2 (pulmonic valve closure). The aortic valve sound (A2) is usually louder than P2. Mitral point is not ideal for hearing S2 clearly, as it's mostly associated with S1 sound.
Choice B rationale:
The tricuspid and aortic points are the most appropriate for hearing the S2 heart sound. The aortic valve (A2) is best heard at the second right intercostal space close to the sternum, and the tricuspid valve is best heard at the lower left sternal border.
Choice C rationale:
While the mitral and tricuspid points are important for auscultating the heart sounds, they are more associated with the S1 sound (the first heart sound). The S2 sound is best heard at the aortic and pulmonic areas.
Choice D rationale:
The aortic and pulmonic points are important for assessing the S2 heart sound, but they are not the most optimal locations. The aortic valve sound is heard most clearly at the second right intercostal space, whereas the pulmonic valve sound is heard at the second left intercostal space.
