Correct Answer: D

Rationale: Crepitus around the chest tube insertion site may indicate subcutaneous emphysema, a serious condition that requires immediate attention. It can be a sign of an air leak in the lung or surrounding tissues. Constant bubbling in the suction control chamber is expected in a functioning chest tube system as it indicates proper suction. Intermittent bubbling in the water seal chamber is also normal, showing that the system is functioning correctly, allowing air to escape but not re-enter. Drainage of 50 ml per hour is within the expected range for chest tube output and does not require immediate intervention unless there are other concerning signs such as rapid increase or a sudden change in color or consistency.

Correct Answer: C

Rationale: Tuberculosis is transmitted through airborne particles, so airborne precautions are necessary to prevent the spread of the disease. Airborne precautions (Choice C) involve measures such as negative pressure rooms and N95 respirators to prevent the transmission of infectious agents that remain infectious over long distances when suspended in the air. Contact precautions (Choice A) are used for diseases that spread through direct contact with the patient or their environment. Droplet precautions (Choice B) are for diseases transmitted through respiratory droplets, typically over short distances. Protective environment (Choice D) is used for clients who are immunocompromised to protect them from environmental pathogens, not for diseases like tuberculosis that spread through the air.

Correct Answer: A

Rationale: To prevent skin impairment in a patient with a cast, the nurse should assess surfaces exposed to the edges of the cast for pressure areas. This is important to prevent pressure ulcers or skin breakdown. Keeping the patient's blood pressure low (Choice B) is not directly related to preventing skin impairment in this scenario. Allowing turning in bed (Choice C) is essential for preventing complications like pressure ulcers and is not contraindicated. Encouraging the patient's dietary intake (Choice D) to maintain hydration is not directly related to preventing skin impairment associated with a cast.

Correct Answer: D

Rationale: The correct answer is 'D: sunny side up (fried) eggs.' Fried eggs should be removed as they are not suitable for a mechanical soft diet due to their texture. The yolk of a fried egg is usually too hard and can be difficult for a client on a mechanical soft diet to chew and swallow. Poached or scrambled eggs are better alternatives for this diet as they are softer and easier to consume. Choices A, B, and C are all suitable for a mechanical soft diet as they are softer in texture and easier to chew and swallow.

Correct Answer: B

Rationale: After applying sterile gloves, the nurse should proceed to remove the sutures using sterile technique. This step ensures the safe and effective removal of sutures without introducing infection. Choice A, cleaning sutures along the incision site, would not be the next step as the primary focus is on suture removal. Inspecting the wound for signs of infection (Choice C) is important but typically follows suture removal. Documenting the removal of sutures (Choice D) is essential but usually occurs after the procedure is completed.
