Correct Answer: B

Rationale: The correct answer is 'Hispanic.' Hispanics are the largest and fastest-growing population in the United States. While African Americans/Blacks, Asians, American Indians, and other groups are significant, Hispanics currently represent the largest demographic group. African American/Black, Asian, and American Indian populations are substantial but not as large or fast-growing as the Hispanic population. Therefore, Hispanic is the most appropriate choice in this scenario.

Correct Answer: D

Rationale: During the examination of a 16-year-old male teenager, it is essential to provide feedback that his body is developing normally and to discuss the wide variation among teenagers regarding growth and development. This reassures the teenager about his health status and addresses any concerns about physical development. It is important to recognize that adolescents are very conscious of their body image and often compare themselves to their peers, hence the need for such feedback. Asking the parent to step out of the room respects the teenager's privacy and promotes open communication between the nurse and the teenager. Using age-appropriate communication is crucial to ensure that the teenager understands the information provided. Asking the parent to stay in the room may not be ideal as it can inhibit open discussion, and talking to the teenager as if they were a younger child is inappropriate and may undermine their autonomy and understanding.

Correct Answer: A

Rationale: The small charm tied to a leather strip is likely an amulet, which many cultures consider an important means of protection from 'evil spirits.' When a patient appears to have a health practice the nurse is unfamiliar with, the nurse should ask for clarification in a non-judgmental way that communicates acceptance of their beliefs and allows for open communication. Thus, the nurse in this situation should inquire about the amulet's meaning to the patient. Asking the patient to lock the item with other valuables in the hospital's safe, telling the patient that a family member should take valuables home, or doing nothing does not address the importance or meaning of a cultural health practice to the patient and does not allow the nurse to gain an understanding of the patient's cultural health practices.

Correct Answer: B

Rationale: During a physical assessment, the nurse should always begin with inspection. The sequence of techniques for physical examination is inspection, palpation, percussion, and auscultation. These skills are performed in a specific order, except for the abdominal assessment where auscultation precedes palpation and percussion. Inspection allows the nurse to observe and gather initial information without direct contact. It is a crucial step that provides valuable insights before proceeding to palpation, percussion, and auscultation. Therefore, choice B, 'Inspection,' is the correct answer. Choices A, C, and D are incorrect because they should follow inspection in the sequence of a comprehensive physical assessment.

Correct Answer: B

Rationale: The stethoscope does not magnify sound but effectively blocks out extraneous room noises. The correct orientation of the earpieces is with the slope pointing forward toward the examiner's nose, not posteriorly. The tubing length of a stethoscope should ideally be between 14 to 18 inches (36 to 46 cm) to avoid sound distortion. Using tubing longer than this range can distort sound. Both the fit and quality of the stethoscope are crucial for accurate auscultation and assessment, highlighting their significance in clinical practice. Therefore, the correct answer is that the stethoscope blocks out extraneous room noise but does not magnify sound.
