The autoclave helps prevent infection because

Correct Answer: C

Rationale: The autoclave uses high pressure and temperature to sterilize objects by killing all microorganisms, including spores. This process ensures that no viable microorganisms remain on the objects, effectively preventing infection. Choice A is incorrect as some spores can be eliminated by the autoclave. Choice D is incorrect because disinfection does not guarantee the elimination of all microorganisms. Choice C is the correct answer as sterilization ensures the complete destruction or removal of all forms of microbial life, making the object safe for use.

Correct Answer: A

Rationale: The correct answer is A: A bath blanket. A bath blanket is used to cover a resident while making an occupied bed to respect their right to privacy. It provides temporary coverage and maintains the resident's dignity. Incorrect choices: B: A bedspread is not suitable for covering a resident during bed-making as it is too heavy and may cause discomfort. C: A waterproof bed protector is used to protect the mattress from spills and accidents, not to cover a resident during bed-making. D: A fitted bottom sheet is used to cover the mattress, not the resident, during bed-making.

Correct Answer: B

Rationale: The correct answer is B: Edema. Edema refers to swelling in body tissues caused by excess fluid. Emesis (A) means vomiting, not swelling. Enema (C) is a procedure involving the introduction of fluid into the rectum. Eczema (D) is a skin condition characterized by inflammation and itching, not related to fluid accumulation. Thus, B is the correct choice for the medical term describing swelling due to fluid retention.

Correct Answer: C

Rationale: Fluid overload can occur when the kidneys and lungs are not working properly. The kidneys regulate fluid balance by filtering and excreting excess fluid as urine. If the kidneys are impaired, excess fluid can accumulate in the body leading to fluid overload. The lungs play a role in maintaining fluid balance through respiration, as they help regulate the amount of water vapor lost during breathing. If the lungs are not functioning properly, fluid can accumulate in the lungs and other tissues, contributing to fluid overload. Choices A, B, and D are incorrect as they do not directly impact fluid balance regulation in the body.

Correct Answer: A

Rationale: The correct answer is A because electrolytes help maintain normal fluid balance in the body by regulating fluid levels inside and outside cells, enabling proper nerve and muscle function. Choice B is incorrect because electrolytes are not related to nutritional intake. Choice C is incorrect as electrolytes do not directly affect absorption of nutrients. Choice D is incorrect as electrolytes do not play a role in elimination processes. Maintaining normal fluid balance is crucial for overall health and electrolytes play a vital role in achieving this balance.
