The nurse is to administer a volume of 2 mL intramuscularly (IM) to a 150-pound client.
Assuming that there are no skin problems, which is the preferred site for the injection?
Deltoid
Dorsogluteal
Ventrogluteal
Vastus lateralis
Choice A rationale: The deltoid muscle may not accommodate larger volumes as comfortably as other sites. Choice B rationale: The dorsogluteal site is not recommended due to the risk of injury to the sciatic nerve. Choice C rationale: The ventrogluteal site is the preferred site for IM injections in adults, providing a safe and well-vascularized muscle. Choice D rationale: The vastus lateralis is a suitable site for infants and young children but may not be the most comfortable for adults receiving a 2 mL injection.

Correct Answer is B
Explanation
Choice A rationale: Poor tissue perfusion from circulatory insufficiency can affect oxygenation, but fluid in the lungs primarily impacts gas exchange at the alveolar level.
Choice B rationale: Decreased diffusion of oxygen from the alveoli to the blood is a major factor affecting oxygenation when fluid is present in the lungs.
Choice C rationale: Lowered oxygen carrying capacity can affect oxygenation but is not the primary concern in the presence of fluid in the lungs.
Choice D rationale: Decreased concentration of oxygen in the air is not the primary factor affecting oxygenation in a client with fluid in the lungs.

Correct Answer is C
Explanation
Choice A rationale: The normal stimulus to breathe is an increased carbon dioxide level, which stimulates the respiratory center in the brain.
Choice B rationale: Increased oxygen levels do not serve as the primary stimulus for breathing. The respiratory center is primarily responsive to carbon dioxide levels.
Choice C rationale: Increased carbon dioxide level is the correct stimulus for normal breathing.
Choice D rationale: Decreased oxygen level is not the primary stimulus for normal breathing.
