Correct Answer: A

Rationale: Specific gravity measures the concentration of solutes in the urine, reflecting the kidney's ability to concentrate or dilute urine. Choice B, bacteria in the urine, is incorrect because specific gravity does not measure bacterial presence. Choice C, pH level of the urine, is incorrect as it refers to the acidity or alkalinity of the urine, not its specific gravity. Choice D, glucose in the urine, is incorrect as specific gravity does not directly measure glucose levels in urine.

Correct Answer: D

Rationale: The correct answer is D: Normal breath sounds. In the scenario described, the nurse hears normal bronchovesicular breath sounds, which are moderate in intensity and resemble blowing as air moves through the larger airways during inspiration and expiration. Crackles (choice A) are typically heard in conditions like heart failure or pneumonia and are not present in this case. Rhonchi (choice B) are low-pitched, continuous sounds often associated with conditions like chronic bronchitis or bronchiectasis. Friction rub (choice C) is a grating sound usually heard in conditions like pleurisy or pericarditis, which is not the case here where normal breath sounds are heard.

Correct Answer: D

Rationale: The high-Fowler position is preferred after neck surgery to reduce edema at the operative site. Elevating the head of the bed promotes venous return and drainage, aiding in decreasing swelling and fluid accumulation, which helps reduce edema at the operative site. Choice A is incorrect as the main purpose is not solely about reducing strain on the incision. Choice B is incorrect because while drainage may occur, it is not the primary reason for maintaining the high-Fowler position. Choice C is incorrect as providing stimulation is not the primary rationale for positioning the client in high-Fowler.

Correct Answer: A

Rationale: The correct answer is A: 'Is unable to swallow foods by mouth.' Tube feeding is prescribed when a client is unable to safely swallow food by mouth but has a functional gastrointestinal tract. Option B, 'Has a gastrointestinal obstruction,' is incorrect as tube feeding is not typically prescribed for this reason. Option C, 'Requires additional caloric intake to support healing,' is incorrect because tube feeding is specifically for clients who are unable to swallow. Option D, 'Is at risk for aspiration,' is also incorrect as tube feeding would not be the primary intervention for aspiration risk; other strategies to reduce aspiration risk would be implemented instead.

Correct Answer: B

Rationale: The correct answer is B: Preschooler. Family customs have a significant impact on hygiene practices during childhood, especially in the early years. Preschoolers are at an age where they are learning and forming habits, and family customs play a crucial role in establishing routines such as bathing and brushing teeth. Adolescents, older adults, and adults are more likely to have established their own hygiene routines that may not be as heavily influenced by family customs as in early childhood. Therefore, the nurse is most likely providing care to a preschooler in this scenario.
