Which of the following statements is true?

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: 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.

Correct Answer: B

Rationale: The correct answer is B: Epidermis. The epidermis is the outer layer of the skin and is composed of dead cells that continuously shed and are replaced by new cells. The integument (choice A) refers to the entire skin organ, not just the outer layer. The dermis (choice C) is the layer beneath the epidermis and contains blood vessels, nerves, and connective tissues. Melanocytes (choice D) are cells within the epidermis that produce the pigment melanin, responsible for skin color, but they are not the outer layer of the skin composed of dead cells.

Correct Answer: A

Rationale: Step 1: Angina is chest pain or discomfort caused by reduced blood flow to the heart muscle. Step 2: Emotional distress can trigger angina episodes, so reducing distress is important. Step 3: Managing stress can help prevent angina attacks and improve overall well-being. Step 4: Choice A is correct because emotional distress can worsen angina symptoms. Summary: Choice B is incorrect because only healthcare professionals can administer nitroglycerin. Choice C is incorrect because large meals can strain the heart and worsen angina. Choice D is incorrect because while exercise is important, it should be done in moderation for angina patients.
