When assessing a client's abdomen, particularly for "stomach pain," the nurse should:

Choice A reason: While providing a newborn's first bath, there is minimal risk of exposure to infectious fluids that would necessitate eye protection. However, standard precautions should always be followed.

Choice B reason: When giving personal care to an infant who is HIV-positive, standard precautions should be followed, which includes wearing gloves. Eye protection is not typically required unless there is a risk of splashing bodily fluids.

Choice C reason: Suctioning secretions from a child's newly placed tracheostomy tube requires eye protection because there is a high risk of secretions being expelled forcefully, which could contact the mucous membranes of the eyes.

Choice D reason: Withdrawing cord blood from a neonate generally does not require eye protection unless there is a risk of blood splatter. Standard precautions, including the use of gloves, should be sufficient.

Choice E reason: Transporting a cerebrospinal fluid specimen to the laboratory does not require the nurse to wear eye protection. However, the nurse should ensure that the specimen is sealed properly to prevent any leaks.

Choice A reason: Wearing gloves when measuring a client's blood pressure is not typically necessary unless there is a risk of exposure to bodily fluids or if the client has an infectious disease. The use of gloves is based on the type of contact and potential for exposure, not routine tasks like BP measurement.

Choice B reason: Wearing gloves for all client contact is not necessary and is not consistent with standard precautions. Gloves should be used when there is potential contact with blood, body fluids, secretions, excretions, contaminated items, or mucous membranes.

Choice C reason: Gloves are not a substitute for hand hygiene. The primary reason for wearing gloves is to provide a barrier against infection, not to reduce handwashing. Hand hygiene is still required before donning gloves and after removing them, regardless of whether the gloves are soiled or not.

Choice D reason: Wearing gloves and a gown when bathing a client with open skin lesions is correct because it protects both the healthcare worker and the client from the risk of infection. Open skin lesions can be a source of infection, and PPE is necessary to prevent the transmission of pathogens.
