NCLEX RN Exam Preview Answers - Nurselytic

Correct Answer: B

Rationale: The correct instrument to assess a murmur while auscultating heart sounds is the bell of the stethoscope. An electrocardiogram is used to measure the heart's electrical activity, not to assess murmurs. Palpation with the nurse's palm of the hand is a method to assess pulses or textures, not heart murmurs. The diaphragm of the stethoscope is typically used for high-pitched sounds like breath, bowel, and normal heart sounds, whereas the bell is more suitable for soft, low-pitched sounds such as murmurs or extra heart sounds.

Correct Answer: B

Rationale: Religion refers to an organized system of beliefs concerning the cause, nature, and purpose of the universe, as well as the attendance of regular services. Religion is a shared experience of spirituality or the values, beliefs, and practices into which people are either born or that they may adopt to meet their personal spiritual needs through communal actions, such as religious affiliation, attendance and participation in a religious institution, prayer, or meditation, and religious practices. Culture is a complex phenomenon that includes attitudes, beliefs, self-definitions, norms, roles, and values learned from birth through the processes of language acquisition and socialization. It does not refer to a belief in a divine or superhuman power. Ethnicity pertains to a social group within the social system that claims to possess variable traits, such as a common geographic origin, religion, race, and others. Spirituality is a broad term focused on a connection with something bigger than oneself and a belief in transcendence.

Correct Answer: D

Rationale: When preparing to auscultate the abdomen, it is important to ensure the patient's comfort. The room should be warm to prevent shivering, which can interfere with sound clarity. Offering blankets to the patient if they feel cold helps maintain their comfort during the examination. The endpiece of the stethoscope should be warmed by rubbing it between the examiner's hands, not by placing it in warm water. It is important to use the diaphragm, not the bell, of the stethoscope to auscultate for bowel sounds.
Therefore, choice D is the correct answer, as it addresses the patient's comfort and the room temperature, which are essential for a successful abdominal auscultation.

Correct Answer: A

Rationale: For performing a physical examination on an infant, it is important to have the parent remove all clothing except the diaper to allow for a thorough examination while ensuring the infant remains comfortable. It is recommended not to feed the infant immediately before the examination but rather 1 to 2 hours after feeding when the baby is neither too drowsy nor too hungry. While a pacifier may be used during invasive assessments or if the infant is crying, it is not typically necessary during abdominal auscultation. Having the parent present during the examination is important for the infant's security and for the parent to understand the process; however, the clothing should still be removed except for the diaper to facilitate a comprehensive assessment.

Correct Answer: B

Rationale: The correct answer is the dorsal surface of the hand. The dorsa (backs) of the hands and fingers are best for determining temperature because the skin is thinner on the dorsal surfaces than on the palms. Fingertips are best for fine, tactile discrimination and not for assessing skin temperature. The ulnar and palmar surfaces of the hands are not as effective for assessing skin temperature as the dorsal surface because they have thicker skin layers.
