A pulse oximeter measures

Correct Answer: C

Rationale: The correct answer is C: Blood oxygen level. A pulse oximeter measures the oxygen saturation level in the blood, indicating how well oxygen is being carried to the body's tissues. It does this by shining light through the skin to detect the amount of oxygen-bound hemoglobin in the blood. Choice A, blood pressure, is measured using a sphygmomanometer. Choice B, body temperature, is typically measured using a thermometer. Choice D, blood glucose level, is measured using a glucometer. Thus, the correct answer is C as it directly aligns with the function and purpose of a pulse oximeter.

Correct Answer: B

Rationale: The correct answer is B: They should not be worn in care facilities. Artificial nails can harbor bacteria and pose infection risks in long-term care settings. They may also interfere with proper hand hygiene practices. Choice A is incorrect because clean, short, and filed artificial nails still pose infection risks. Choice C is incorrect because wearing artificial nails only at special events does not address the overall infection risk. Choice D is incorrect as frequent hand washing alone may not eliminate the risks associated with artificial nails.

Correct Answer: D

Rationale: The correct answer is D: Scopy in endoscopy. A suffix is a word part added to the end of a root word to modify its meaning. In this case, "scopy" is a suffix added to the root word "endo" to form the word "endoscopy," meaning visual examination within. Choices A, B, and C are all prefixes, not suffixes. Prefixes are word parts added to the beginning of a root word to modify its meaning. In choices A, B, and C, "broncho," "rhino," and "neuro" are all added to the root words "scopy," "plasty," and "pathy," respectively, to form new words.

Correct Answer: D

Rationale: The correct answer is D: 1 to 3 years old. Toddlers are typically children between the ages of 1 to 3 years old. During this stage, children begin to develop their independence and motor skills. Choices A, B, and C are incorrect because they do not accurately represent the age range associated with toddlers. Option A (2 to 4 years old) includes children beyond the toddler stage, option B (6 to 12 years old) covers school-age children, and option C (3 to 6 years old) also includes children beyond the toddler years. The key defining factor of toddlers is their age range of 1 to 3 years old.

Correct Answer: D

Rationale: The correct answer is D because using a communication board helps the resident with a functional barrier to communicate effectively. By using the board, the resident can ask questions and express their needs despite any limitations they may have. This approach promotes autonomy and maintains the resident's dignity. Choice A is incorrect as preventing the resident from resting goes against their well-being and comfort. Choice B is incorrect because removing oxygen can endanger the resident's health. Choice C is incorrect as encouraging the resident to speak quickly could lead to frustration and may not be suitable for someone with a functional barrier affecting their speech.
