Which of the following is true of sleep?

Correct Answer: C

Rationale: The correct answer is C because lack of sleep can indeed cause decreased mental function. Sleep is crucial for cognitive processes, memory consolidation, and overall brain function. Without sufficient sleep, individuals may experience difficulty concentrating, memory lapses, and impaired decision-making. Choice A is incorrect because the elderly actually tend to have more difficulty falling asleep due to changes in sleep patterns with age. Choice B is incorrect as the elderly are more sensitive to the effects of sleep deprivation. Choice D is incorrect as consistent lack of sleep can lead to various health issues, impacting overall well-being.

Correct Answer: A

Rationale: The correct answer is A. Residents' hair should be handled gently to avoid pulling it out while combing or brushing. This is important for maintaining their comfort and preventing hair loss. Choice B is incorrect as hairstyles should be chosen based on residents' preferences and comfort, not based on looking cute. Choice C is incorrect as cutting residents' hair should be done by a professional hairdresser, not by nursing assistants. Choice D is incorrect as pediculosis (lice) can indeed spread quickly if not treated promptly and properly.

Correct Answer: D

Rationale: The correct answer is D: Warmth or medication. Warmth can help relax muscles and increase blood flow, reducing pain. Medications like analgesics can block pain signals. Pounding on the back (A) and doing jumping jacks (B) can worsen pain by causing further injury. Squeezing the body part (C) can provide temporary relief but doesn't address the underlying cause of pain.

Correct Answer: A

Rationale: To convert ounces to milliliters, the nursing assistant should multiply by 30 because 1 ounce is approximately equal to 30 milliliters. Therefore, multiplying the number of ounces by 30 will give the equivalent amount in milliliters. Choice B (20) is incorrect because the conversion factor for ounces to milliliters is not 20. Choice C (60) is incorrect because it is not the standard conversion factor used for ounces to milliliters. Choice D (15) is incorrect because it is not the correct conversion factor. The correct choice is A (30) as it corresponds to the standard conversion rate.

Correct Answer: A

Rationale: The correct answer is A because burning or pressure when urinating can indicate a urinary tract infection or other issue that requires medical attention. This symptom may suggest an underlying infection or inflammation in the urinary system. Reporting this to the nurse promptly can lead to early diagnosis and treatment. Choices B, C, and D are incorrect as they do not indicate any immediate health concern. Urinary output within the range of 1200 to 1500 mL per day is considered normal. The color of urine can vary based on hydration levels and dietary intake, so pale yellow or clear urine is not necessarily alarming.
