Correct Answer: B

Rationale: The correct response is to instruct the client that the stoma will become smaller when the initial swelling diminishes. This explanation helps reassure the client about the temporary appearance of the stoma. Choice A is incorrect because simply reassuring the client that he will become accustomed to the stoma's appearance does not address the immediate concern about the stoma size. Choice C is incorrect because offering to contact a support group does not directly address the client's current distress about the stoma size. Choice D is incorrect because encouraging the client to handle stoma equipment does not directly address the client's concern about the stoma size and may not be appropriate at this time.

Correct Answer: C

Rationale: The correct answer is C. Protecting others from exposure when transporting a client with MRSA is crucial in preventing the spread of infection. This statement demonstrates understanding of infection control measures. Stating that MRSA is usually resistant to vancomycin (choice B) is incorrect; vancomycin is often effective against MRSA. Obtaining a specimen for culture and sensitivity after the first dose of an antimicrobial (choice A) is unnecessary and not indicated. Discontinuing antimicrobial therapy when the client is no longer febrile (choice D) is incorrect because antimicrobial therapy should be completed as prescribed to prevent the development of resistant strains.

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: A

Rationale: The correct intervention is to assist the client back to bed. A decrease in oxygen saturation while ambulating indicates hypoxemia, and the immediate priority is to stabilize oxygen levels. Returning the client to bed allows for rest and decreased oxygen demand, potentially preventing further desaturation. Encouraging continued ambulation (Choice B) may worsen the hypoxemia by increasing oxygen demand. Obtaining portable oxygen (Choice C) is essential but should not delay addressing the low oxygen saturation. Moving the oximetry probe (Choice D) may not address the underlying cause of decreased oxygen saturation and should not be the first intervention.

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.
