There are _____ inches in a foot.

Correct Answer: B

Rationale: The correct answer is B: 2. There are 12 inches in a foot. This conversion is a fundamental unit of measurement in the imperial system. To arrive at this answer, you simply need to recall the basic conversion between feet and inches. Choice A is incorrect as it doesn't align with the established conversion. Choice C is incorrect as it is not the standard conversion ratio between feet and inches. Choice D is incorrect as it is an excessively large number compared to the actual conversion.

Correct Answer: C

Rationale: The correct answer is C because placing a towel or bed pad under the part of the body being washed helps maintain the resident's dignity and comfort, prevents skin irritation, and keeps the bed dry. It also ensures proper hygiene practices by reducing the risk of contamination. A is incorrect because washing the anal area before the perineal area can increase the risk of spreading bacteria. B is incorrect because using water at 0°F would be dangerously cold. D is incorrect because uncovering the entire body at once may make the resident feel exposed and uncomfortable.

Correct Answer: A

Rationale: The correct answer is A because counting respiration rate immediately after taking the pulse minimizes errors and ensures accuracy. By keeping the fingers on the wrist, the nursing assistant can seamlessly transition from counting pulses to counting respirations without missing a beat. This method saves time and effort, making it a practical approach in a clinical setting. Choice B is incorrect because the act of observing does not significantly impact respiration rate in this context. Choice C is incorrect because the chest will continue to rise and fall even if the rate is not counted immediately. Choice D is incorrect because waiting to take the respiration rate can lead to inaccurate readings due to potential changes in the breathing pattern.

Correct Answer: B

Rationale: The correct answer is B: Serving favorite foods. This can be an effective way to prevent unintended weight loss because it ensures that the resident is more likely to eat and enjoy their meals, leading to adequate nutrient intake. By serving favorite foods, the resident is more likely to have a positive dining experience, which can help maintain their appetite and prevent weight loss. A: Promoting independence by insisting residents feed themselves without help can lead to unintended weight loss if the resident struggles to eat independently. C: Telling the resident when a meal looks unappetizing may discourage them from eating, leading to unintended weight loss. D: Insisting that residents eat everything on their trays no matter what can be counterproductive as it may lead to stress or discomfort during meals, potentially causing weight loss.

Correct Answer: B

Rationale: The correct answer is B: Squatting and leaning forward. This position aligns the rectum with the anal canal, facilitating easier bowel movement. Squatting relaxes the puborectalis muscle, making defecation more efficient. Lying flat on the bed (A) does not promote proper alignment. Lying on the stomach (C) can cause strain. Sitting straight (D) can create an angle that makes elimination difficult.
