Using the principles of standard precautions, the nurse would wear gloves in what nursing interventions?

Correct Answer: D

Rationale: Standard precautions are infection control practices used to prevent the transmission of pathogens in healthcare settings. They apply to all patient care situations where there is potential contact with blood, body fluids, secretions, excretions (except sweat), non-intact skin, or mucous membranes. Providing oral hygiene involves direct contact with saliva, which is considered a body fluid that may contain pathogens, such as bacteria or viruses, especially in patients with poor oral health or infections. Wearing gloves during this intervention protects the nurse from potential exposure to infectious agents and prevents cross-contamination to other patients or surfaces. In contrast, providing a back massage, feeding a client, or providing hair care typically does not involve contact with body fluids or high-risk areas unless specified otherwise (e.g., open wounds or soiled conditions). Therefore, gloves are not routinely required for these tasks under standard precautions unless additional risk factors are present. The correct answer is D because oral hygiene uniquely involves potential exposure to mucous membranes and saliva, necessitating glove use.
