Which of the following is true of Transmission-Based Precautions?

Correct Answer: C

Rationale: The correct answer is C because Transmission-Based Precautions are used in addition to Standard Precautions for patients with known or suspected infections. Step 1: Standard Precautions are the basic level of infection control practices that should be applied to all patients. Step 2: Transmission-Based Precautions are additional precautions used for patients with specific infectious conditions to prevent the spread of pathogens. Step 3: Therefore, practicing Transmission-Based Precautions alongside Standard Precautions ensures proper infection control measures are taken for patients with infectious diseases. Choices A and B are incorrect because Standard Precautions apply to all patients, and Transmission-Based Precautions are not the same as Standard Precautions. Choice D is incorrect because listing Transmission-Based Precautions in the care plan is essential for ensuring proper infection control practices are followed.

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: B

Rationale: The correct answer is B: Bariatrics. Bariatrics is the branch of medicine that specifically focuses on the prevention and treatment of obesity. This field involves medical and surgical approaches to help individuals manage their weight and improve their overall health. Obstetrics (A) deals with pregnancy and childbirth, not obesity. Pediatrics (C) focuses on the medical care of children. Dietetics (D) is the science of nutrition and the regulation of diet, but it does not specifically address the prevention and treatment of obesity like bariatrics does.

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.
