The autoclave helps prevent infection because

Correct Answer: C

Rationale: The autoclave uses high pressure and steam to sterilize objects, killing all microorganisms including spores. This ensures that no infectious agents are present on the items being sterilized, preventing infections. Choices A and D are incorrect because the autoclave does not make the facility entirely free of microorganisms and it is not used to disinfect disposable equipment. Choice B is incorrect as autoclaves are designed to eliminate spores through sterilization. Therefore, choice C is correct as it accurately describes the main function of an autoclave.

Correct Answer: A

Rationale: The correct answer is A: A bath blanket. When making an occupied bed to promote a resident's right to privacy, a bath blanket is used to cover the resident. This item provides adequate coverage while maintaining the resident's dignity. A bath blanket is specifically designed for this purpose, ensuring the resident's privacy is respected during the bed-making process. Summary: - B: A bedspread is not suitable for covering a resident during bed-making as it is typically heavier and not designed for this purpose. - C: A waterproof bed protector is used to protect the mattress from spills and accidents, not for covering the resident. - D: A fitted bottom sheet is used to cover the mattress, not the resident, and does not provide adequate privacy during bed-making.

Correct Answer: B

Rationale: The correct answer is B: Edema. Edema refers to swelling in body tissues caused by excess fluid accumulation. Emesis (A) is the medical term for vomiting, not swelling. Enema (C) is a procedure to introduce fluid into the rectum, not related to swelling. Eczema (D) is a skin condition characterized by red, itchy patches, not swelling due to excess fluid. Therefore, B is the correct answer as it specifically relates to swelling caused by fluid retention.

Correct Answer: C

Rationale: The correct answer is C: Kidneys and lungs. Kidneys regulate fluid balance by filtering and excreting excess fluids. If the kidneys are not functioning properly, fluid overload can occur. Lungs play a role in maintaining fluid balance through respiration. If the lungs are compromised, fluid can accumulate in the body. Stomach, colon, esophagus, small intestine, liver, and appendix do not directly regulate fluid balance. Therefore, choices A, B, and D are incorrect.

Correct Answer: A

Rationale: The correct answer is A: Normal fluid balance. Electrolytes are essential for maintaining proper fluid balance in the body by regulating water movement across cell membranes. They help with nerve function, muscle contraction, and maintaining pH levels. Choice B, suitable nutritional intake, is incorrect as electrolytes are not related to dietary intake. Choice C, proper absorption, is incorrect as electrolytes do not directly aid in absorption. Choice D, adequate elimination, is incorrect as electrolytes do not play a direct role in elimination processes.
