HESI Fundamentals Exam Test Bank

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, Pinworms. Pinworms are a common cause of itching around the anal area, especially at night, in young children. Scratching the bottom and bedwetting can be indicative of a pinworm infection. Allergies (Choice A) are less likely given the symptoms described. Scabies (Choice B) may cause itching but is less common in causing bedwetting. Regression (Choice C) is not a common cause of these specific symptoms in a 3-year-old child.

Correct Answer: C

Rationale: In a 2-year-old child with diarrhea and a possible ear infection, rectal temperature measurement is the most accurate reflection of core body temperature. This method provides the most reliable reading, especially in young children, as it closely reflects the core body temperature. Oral temperature may not be accurate due to the child's recent diarrhea, which can affect oral readings. Axillary temperature may not be as accurate as rectal temperature in this case. Temporal temperature measurement, although non-invasive, may not provide the most accurate core body temperature reading, especially in a child with a potential ear infection.

Correct Answer: A

Rationale: Filling the ice bag two-thirds full is the correct action as it ensures the effectiveness of the ice application while allowing some space for the ice to move and conform to the injury. Choice B is incorrect because the ice bag should be applied with a barrier like a cloth to prevent direct contact with the skin, which can lead to ice burns. Choice C is wrong as ice should typically be applied for 20 minutes at a time to avoid tissue damage. Choice D is also incorrect as ice is preferred over frozen gel packs for immediate sports injury management.

Correct Answer: C

Rationale: The correct answer is potato chips. As a child with celiac disease needs to avoid gluten, potato chips are a suitable snack choice as they are typically gluten-free. Cheese crackers (Choice A) and vanilla cookies (Choice D) contain gluten, which should be avoided by individuals with celiac disease. While peanut butter sandwiches (Choice B) could be gluten-free depending on the bread used, it is not the best choice as cross-contamination is a concern in shared environments like daycare centers.
