Which of the following is true of sleep?

Correct Answer: C

Rationale: The correct answer is C: Lack of sleep can cause decreased mental function. This is true because sleep is essential for cognitive function and overall well-being. Lack of sleep can impair memory, concentration, decision-making, and mood. It can also lead to slower reaction times and decreased performance in various tasks. Choice A is incorrect because the elderly generally have more sleep disturbances and take longer to fall asleep. Choice B is incorrect as older adults are actually more sensitive to the effects of sleep deprivation. Choice D is incorrect because consistent lack of sleep can lead to various health issues and impact overall well-being.

Correct Answer: A

Rationale: The correct answer is A because residents' hair should be handled gently to prevent hair loss. Pulling or tugging on the hair can cause damage to the hair follicles and lead to hair loss. It is important to be gentle when combing or brushing elderly residents' hair to maintain their hair health. Choice B is incorrect because hairstyles should be chosen based on residents' preferences and comfort, not based on aesthetic appeal. Choice C is incorrect because cutting residents' hair should be done by trained professionals unless the resident requests it specifically. Choice D is incorrect because pediculosis can spread quickly through close contact or shared personal items.

Correct Answer: D

Rationale: The correct answer is D: Warmth or medication. Warmth can help relax muscles and increase blood flow, reducing pain. Medications such as pain relievers can also help alleviate pain. Pounding on the back (choice A) and jumping jacks (choice B) can actually worsen pain by causing further strain. Squeezing the body part (choice C) may provide temporary distraction but does not address the root cause of the pain.

Correct Answer: A

Rationale: To convert ounces to milliliters, the nursing assistant should multiply by 30. This is because 1 fluid ounce is equivalent to approximately 30 milliliters. By multiplying the number of ounces by 30, you can accurately convert the volume to milliliters. Choice B (20) and Choice D (15) are incorrect because they do not reflect the correct conversion rate of ounces to milliliters. Choice C (60) is also incorrect as it is the inverse of the correct conversion rate, leading to an inaccurate result.

Correct Answer: A

Rationale: The correct answer is A: Burning or pressure when urinating. This symptom could indicate a urinary tract infection or other health issue that requires immediate attention. Reporting this to the nurse will prompt further assessment and appropriate treatment. Choices B, C, and D are related to normal urinary output and characteristics, which do not necessarily require immediate reporting unless there are significant deviations or accompanying symptoms.
