Correct Answer: A

Rationale: During CPR, chest compressions should be applied at a rate of 100 compressions per minute in order to effectively circulate blood and oxygen to vital organs. Option A, '100 per minute,' is the correct answer as it aligns with the recommended compression rate in CPR guidelines. Option B, '60 per minute,' is incorrect as it is too slow and may not provide adequate circulation. Option C, 'As quickly as possible,' is vague and does not specify the recommended compression rate. Option D, '200 per minute,' is incorrect as it exceeds the recommended rate and may not be as effective in maintaining perfusion.

Correct Answer: B

Rationale: Surgical asepsis refers to the process of maintaining a sterile environment to prevent the introduction of pathogens to a patient's body. Sterilizing instruments is a crucial aspect of surgical asepsis as it ensures that the instruments used during procedures are free from microorganisms that could cause infections. Wiping down exam tables with bleach may help in cleaning and disinfecting surfaces but does not pertain directly to maintaining a sterile field. Changing table paper is important for cleanliness and infection control but is not specifically related to surgical asepsis. Wearing gloves when performing injections is important for standard precautions and preventing the spread of infection but does not encompass the concept of surgical asepsis, which focuses on maintaining a sterile field during invasive procedures.

Correct Answer: B

Rationale: You must wear gloves when transferring breast milk into a baby bottle because breast milk is considered a bodily fluid. It is essential to avoid direct contact to prevent contamination. When preparing infant formula, gloves are not required as formula is not a bodily fluid. Knocking on or opening a patient's door does not involve direct contact with bodily fluids, so gloves are unnecessary in those situations.

Correct Answer: B

Rationale: The client is exhibiting a stage II pressure ulcer. A stage II pressure ulcer develops as a partial thickness wound that affects both the epidermis and the dermal layers of skin. This stage can present with red skin, blisters, or cracking, appearing shallow and moist. However, the ulcer does not extend to the underlying tissues at this stage. Choice A (Stage I) is incorrect as Stage I ulcers involve non-blanchable redness of intact skin. Choices C (Stage III) and D (Stage IV) are incorrect as they involve more severe tissue damage, extending into deeper layers of the skin and underlying tissues, which is not the case in this scenario.
