Correct Answer: A

Rationale: The correct answer is when the client suddenly complains of back pain and has chills. Signs of a transfusion reaction include back pain, chills, dizziness, increased temperature, and blood in the urine. These signs indicate a possible adverse reaction to the blood transfusion. Dependent edema in the extremities is not typically associated with a transfusion reaction. A seizure is not a common sign of a transfusion reaction unless it is due to severe complications. A decrease in heart rate to 60 bpm is not a typical sign of a transfusion reaction, but rather bradycardia may indicate other underlying conditions or medications.

Correct Answer: C

Rationale: When disposing of used patient equipment, such as a Foley catheter, that has come in contact with bodily fluids, it is considered hazardous waste. The correct procedure involves wearing gloves and placing the Foley bag and tubing into a special 'hazardous waste' container. This container is marked as 'Hazardous' and is typically red to indicate the potential danger of its contents. Placing the equipment in a regular trash can, even if placed in a paper bag, is not appropriate as it does not meet the standards for disposing of hazardous waste. Therefore, options A and B are incorrect. Similarly, simply placing the equipment in a 'hazardous waste' container after it is placed in a paper bag is also incorrect as direct disposal into the designated container while wearing gloves is the proper protocol, making option D incorrect.

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.

Correct Answer: C

Rationale: The correct answer is to only drink tap water that has been filtered or boiled before consumption. Immunocompromised clients are susceptible to infections, so it is essential to take precautions to prevent exposure to harmful pathogens. Drinking tap water that has been filtered or boiled helps eliminate potential pathogens that could be harmful to the client's health. Choices A, B, and D do not directly address the issue of avoiding potential pathogens that could compromise the health of an immunocompromised client. Thus, they are incorrect. Hand-washing utensils, avoiding canned foods, and increasing fruit and vegetable consumption are good general hygiene practices but may not specifically address the needs of an immunocompromised client.

Correct Answer: C

Rationale: Feeling a tingling sensation when touching an electrical cord is a warning sign that the device may be malfunctioning. This sensation indicates a potential electrical current leak, which could pose a risk of harm. The correct action is to immediately discontinue the use of the device and send it to the maintenance department for inspection. Continuing to use the device without addressing the issue could lead to electric shock or fire hazards. Trying to plug the device into a different outlet does not address the underlying problem of potential device malfunction. Notifying the supervisor about the risk of an electrical fire is important, but the immediate action should be to stop using the device and have it inspected by maintenance professionals. Therefore, the best course of action is to discontinue the device and ensure it is checked thoroughly before further use.
