Which of the following guidelines is true of working around oxygen equipment?

Correct Answer: A

Rationale: Correct Answer: A Rationale: 1. Oxygen supports combustion and increases fire risk. 2. Open flames near oxygen can cause a fire hazard. 3. Strictly enforce a "no open flames" policy around oxygen equipment. Summary: B: Adjusting oxygen levels is not within the NA's scope of practice. C: Replacing oxygen tubing is important but not specific to guidelines around oxygen equipment. D: Prescribing skin medication is not related to managing oxygen equipment safety.

Correct Answer: A

Rationale: The correct answer is A: Closed bed. A closed bed refers to a bed that is neatly made with bedspread and blankets in place. This term is used in healthcare settings to indicate a bed that is ready for a new patient or for a patient who is not currently in bed. Rationale: 1. Closed bed signifies cleanliness and readiness for use. 2. The term "closed" implies that the bed is fully made and not in use. 3. It helps maintain a hygienic environment and prevents the accumulation of dust or germs on the bed linens. Summary of other choices: B: Open bed - Incorrect because an open bed does not have the bedspread and blankets in place. C: Occupied bed - Incorrect as it refers to a bed that is currently being used by a patient. D: Unoccupied bed - Incorrect because it refers to a bed that is empty but may not necessarily be fully made with bed linens.

Correct Answer: C

Rationale: The correct answer is C: Buttocks. The rationale is that washing the buttocks last prevents the spread of germs from this area to other parts of the body. It follows a logical sequence of cleanliness, starting from cleaner areas like the face and progressing to dirtier areas like the buttocks. Washing the hands earlier is crucial to avoid transferring germs to other body parts. Washing the legs before the buttocks may still spread germs from the dirtiest part (buttocks) to the legs. Washing the face last may lead to transferring germs from the buttocks to the face, which is undesirable.

Correct Answer: C

Rationale: The correct answer is C: 2-20 breaths per minute. This range is the most accurate representation of the normal respiration rate for adults, which typically falls between 12-18 breaths per minute. Options A, B, and D are incorrect because A (8-30 breaths per minute) and B (5-25 breaths per minute) have wider ranges that may include abnormal rates, while D (8-0 breaths per minute) is illogical since a respiration rate of 0 would indicate no breathing, which is incompatible with life. Therefore, option C is the most precise and accurate range for the normal respiration rate in adults.

Correct Answer: B

Rationale: The correct answer is B: Swallowing. Residents who have difficulty swallowing may require thickened liquids to prevent aspiration and choking. Swallowing difficulties, known as dysphagia, can pose serious health risks. Choice A (Walking) is incorrect as it is not directly related to the need for thickened liquids. Choice C (Digesting food) is incorrect because thickened liquids are primarily used to address swallowing issues, not digestion problems. Choice D (Gaining weight) is incorrect as it is not a direct indicator for the need of thickened liquids. Swallowing difficulties are the key factor in determining the necessity of thickened liquids for residents.
