Droplets normally do not travel more than

Correct Answer: A

Rationale: The correct answer is A: Six feet. This is based on the current understanding of how droplets from coughs or sneezes spread in the air. Research indicates that droplets typically travel up to six feet before falling to the ground due to gravity. This distance is commonly cited as the safe distance to maintain during respiratory outbreaks to reduce the risk of transmission. Choices B, C, and D are incorrect because they exceed the generally accepted range of droplet transmission. Two feet (B) is too short a distance, while eight feet (C) and ten feet (D) are beyond the typical range for droplet spread.

Correct Answer: A

Rationale: The correct answer is A: Zero. When weighing a resident, the scale should be balanced at zero to ensure an accurate measurement of the resident's weight. Balancing the scale at zero eliminates any potential errors caused by additional weight on the scale before the resident steps on. Choices B, C, and D are incorrect because starting at any other weight would introduce inaccuracies in the final measurement. Balancing at five pounds, ten pounds, or negative two pounds would result in an incorrect weight reading for the resident.

Correct Answer: C

Rationale: The correct answer is C: Surgical. A surgical bed is designed to accommodate patients who need to return to bed on stretchers or gurneys due to its adjustable height and easy maneuverability. Surgical beds typically have features such as side rails, adjustable backrests, and wheels for easy transportation. A: Open bed does not specify any particular features that would facilitate easy acceptance of patients on stretchers or gurneys. B: Closed bed does not indicate any specific design features related to accommodating patients on stretchers or gurneys. D: Occupied bed refers to a bed that is currently being used by a patient and does not address the design features needed for accepting patients on stretchers or gurneys.

Correct Answer: D

Rationale: The correct answer is D: Perineum. The perineum is the area between the anus and genitals and should be washed daily to maintain proper hygiene and prevent infections. Not washing this area regularly can lead to bacterial growth and unpleasant odors. It is a sensitive area that can easily accumulate sweat and bacteria, making daily washing essential. Now, let's analyze why the other choices are incorrect: A: Hair does not need to be washed daily for most people as it can strip the natural oils and lead to dryness. B: Knees do not need to be washed daily unless they are visibly dirty or sweaty. C: Chest does not necessarily need to be washed daily unless you sweat excessively or engage in activities that make this area dirty.

Correct Answer: D

Rationale: The correct answer is D: Dyspnea. Dyspnea refers to difficulty breathing. The prefix "dys-" means difficult or painful, and "-pnea" refers to breathing. Eupnea (A) means normal breathing, apnea (B) is the absence of breathing, and tachypnea (C) is rapid breathing. Dyspnea specifically denotes the sensation of discomfort or difficulty in breathing, making it the correct term for this condition.
