There are _____ inches in a foot.

Correct Answer: B

Rationale: The correct answer is B (12). There are 12 inches in a foot. This is because a foot is a unit of length in the imperial and US customary systems, and it is defined as 12 inches. Therefore, 1 foot = 12 inches. Explanation for other choices: A: 0 inches in a foot is incorrect because a foot is a unit of measurement that consists of 12 inches. C: 5 inches in a foot is incorrect; a foot is equal to 12 inches. D: 20 inches in a foot is incorrect; a foot is specifically defined as 12 inches.

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 prevent the bed linens from getting wet and provides comfort and warmth to the resident. This step is essential in maintaining the resident's dignity and preventing discomfort. A is incorrect because washing the anal area before the perineal area can lead to cross-contamination. B is incorrect as the water temperature should be warm, not 0°F, to ensure the resident's comfort and safety. D is incorrect as the resident should be kept covered as much as possible to maintain privacy and warmth during the bed bath.

Correct Answer: A

Rationale: Correct Answer: A Rationale: Counting respiration rate directly after pulse helps ensure accuracy as the person's breathing pattern may change quickly. It is convenient to count both while fingers are already placed on the wrist, reducing the need to find the pulse again. This method saves time and effort for the nursing assistant, streamlining the process of vital signs assessment efficiently. Summary of Other Choices: B: This choice assumes that people may consciously alter their breathing rate when observed, which may not necessarily be true in a clinical setting. C: The chest may rise and fall even if the rate is not counted immediately; delaying the count would not affect the chest movements. D: While breathing rates can vary, waiting to take the rate does not guarantee a different result. It is more about ensuring accuracy and efficiency in measurement.

Correct Answer: B

Rationale: The correct answer is B: Serving favorite foods. This is an effective way to prevent unintended weight loss because it increases the likelihood that the resident will enjoy and consume their meals. By serving favorite foods, the resident is more likely to have an appetite and eat enough to maintain their weight. This approach respects the resident's preferences and promotes a positive dining experience. A: Promoting independence by insisting residents feed themselves without help may not be effective if the resident has difficulty feeding themselves, leading to inadequate food intake. C: Telling the resident when a meal looks unappetizing may discourage the resident from eating, resulting in 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 resistance during mealtimes, potentially causing decreased food intake.

Correct Answer: B

Rationale: The correct answer is B: Squatting and leaning forward. This position helps align the rectum for easier elimination by straightening the colon. It mimics a natural squatting position, which relaxes the puborectalis muscle and allows for smoother bowel movements. Lying flat on the bed (A) does not promote proper alignment, lying on the stomach (C) can cause strain, and sitting straight (D) does not facilitate the natural alignment needed for optimal bowel elimination.
