Correct Answer: A

Rationale: The diaphragm of the stethoscope is designed for listening to high-pitched sounds like breath, bowel, and normal heart sounds. It should be firmly held against the person's skin to ensure optimal sound transmission, leaving a ring after use. On the other hand, the bell of the stethoscope is ideal for detecting soft, low-pitched sounds such as extra heart sounds or murmurs. Therefore, the diaphragm is not used to block out low-pitched sounds but rather to enhance the detection of high-frequency sounds.

Correct Answer: B

Rationale: A musical or drum-like sound (tympany) is heard when percussion occurs over an air-filled viscus, such as the stomach or intestines. This indicates the presence of air-filled areas. Constipation, choice A, does not produce specific percussion sounds and is related to bowel movements rather than the sound produced during percussion. The presence of a tumor, choice C, would not typically produce a drum-like sound but might result in dullness or decreased resonance. Dense organs, choice D, would produce a dull thud sound rather than a drum-like tympanic sound.

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.

Correct Answer: A

Rationale: When caring for children with different cultural perspectives, nurses should acknowledge that children have spiritual needs that are influenced by their stages of development. This understanding is crucial as children, like adults, have varying spiritual needs based on their age and the religious environment within their family. Recognizing and addressing these spiritual needs is essential for providing holistic care. Choices B, C, and D are incorrect as they do not accurately reflect the influence of children's developmental stages on their spiritual needs and the importance of considering these needs in their care.

Correct Answer: C

Rationale: During an examination, providing brief educational information to the patient can enhance rapport, as long as the patient can comprehend the terminology. The most appropriate statement from the nurse is "Your pulse is 80 beats per minute, which is within the normal range." This statement conveys a vital sign in a way that is likely understandable to the patient. Choices A, B, and D use terminology that may be unfamiliar or confusing to the patient. Option A mentions 'atrial dysrhythmias,' which might not be clear to the patient. Option B involves terms like 'pitting edema' and 'varicosities,' which could be unfamiliar to the patient. Option D references 'crackles,' 'wheezes,' and 'rubs,' which might not be easily understood by the patient.
