Rationale: The correct answer is B: Orange slices. For a client on a mechanical soft diet, foods that are difficult to chew and swallow should be avoided. Orange slices fall into this category due to their texture and potential choking hazard. Steamed carrots, mashed potatoes, and baked chicken are typically suitable for a mechanical soft diet as they can be easily mashed or cut into small, manageable pieces for consumption.

Rationale: An immunization functions as part of acquired immunity. Acquired immunity involves the production of antibodies after immunization, which helps protect against future infections. Natural immunity is not induced by immunization but is present from birth. Passive immunity is temporary and acquired through the transfer of pre-formed antibodies. Cell-mediated immunity is a type of immune response that involves the activation of phagocytes, antigen-specific cytotoxic T-lymphocytes, and the release of various cytokines in response to an antigen.

Rationale: The correct instruction the nurse should include is to ensure the cane has a rubber tip. This is important as it prevents slipping and ensures safety while walking.

Choice C is incorrect as the cane should be used on the stronger, not the dominant, side for stability. Choice D is incorrect because a cane can be used for support in various situations, not just on stairs.

Correct Answer: C

Rationale: Increased hematocrit indicates hemoconcentration, which is a sign of fluid volume deficit. In FVD, there is a loss of fluid without a proportional loss of electrolytes, leading to hemoconcentration. Choices A, B, and D are incorrect. Decreased hematocrit and decreased white blood cell count are not typical findings in fluid volume deficit. An increased white blood cell count is more indicative of infection or inflammation rather than fluid volume deficit.

Correct Answer: C

Rationale: The correct answer is C. If sterile solution splashes onto the sterile field, it is considered contaminated. Changing gloves in this situation ensures that the sterility of the dressing change is maintained. Choice A is incorrect as non-sterile gloves would introduce contaminants. Choice B is incorrect as layering gloves can increase the risk of contamination. Choice D is incorrect as covering the sterile field with a sterile drape is not the appropriate action to take in response to contamination.
