A nurse is assessing a patient who has chronic bronchitis. The nurse should expect the patient's chest to be which of the following shapes?

Choice A rationale:

The choice "Rectus Femoris" is not the correct answer. The rectus femoris is a muscle located in the thigh and is not a common site for intramuscular injections due to its location and proximity to important structures.

Choice B rationale:

The correct answer is "Vastus Lateralis." Choice B is the correct answer. The vastus lateralis muscle is located on the lateral aspect of the thigh and is a suitable site for intramuscular injections. It is often used in infants and young children or in adults who have limited deltoid muscle mass.

Choice C rationale:

The correct answer is "Dorsogluteal." Choice C is the correct answer. The dorsogluteal muscle, located in the buttocks, has historically been used for intramuscular injections. However, it's important to note that due to the proximity of the sciatic nerve and the potential for incorrect injection technique, this site is used less frequently now.

Choice D rationale:

The choice "Lower abdomen" is not the correct answer. The lower abdomen is not a recommended site for intramuscular injections due to the risk of injuring underlying structures and the potential for subcutaneous injection instead of intramuscular.

Choice E rationale:

The correct answer is "Deltoid." Choice E is the correct answer. The deltoid muscle, located in the upper arm, is commonly used for intramuscular injections, especially for vaccines and smaller medication volumes. However, it has a limited muscle mass and may not be suitable for larger injection volumes.

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.
