Practice HESI Fundamentals Exam

Correct Answer: A

Rationale: The correct answer is 'Pericardial friction rub.' A pericardial friction rub is a high-pitched, scratching sound heard in both systole and diastole, which is characteristic of pericardial inflammation. This sound is different from a murmur, which is a swooshing or blowing sound due to turbulent blood flow. S1 and S2 are normal heart sounds, and a bruit is a whooshing sound caused by turbulent blood flow in an artery, not related to pericardial inflammation.

Correct Answer: A

Rationale: The correct answer is A. The statement 'I will only have to wear this for 6 months' indicates a need for additional teaching because the Milwaukee Brace is typically worn for 12-18 months, not just 6 months. Choice B is correct as inspecting the skin daily is important to prevent skin breakdown. Choice C is correct as the brace is usually worn day and night for effectiveness. Choice D is correct as the brace can be removed when showering to maintain hygiene.

Correct Answer: B

Rationale: The correct answer is B: Hemoglobin. Monitoring hemoglobin levels is essential to assess the effectiveness of epoetin alfa in clients with chronic kidney disease. Epoetin alfa is a medication that stimulates red blood cell production, aiming to increase hemoglobin levels and improve symptoms of anemia in these patients. Monitoring serum potassium (Choice A) is important in clients with kidney disease, but it is more related to assessing electrolyte balance rather than the direct effectiveness of epoetin alfa. Serum creatinine (Choice C) and blood urea nitrogen (Choice D) are kidney function tests that help evaluate kidney health but do not specifically reflect the effectiveness of epoetin alfa therapy.

Correct Answer: C

Rationale: The correct answer is C because for a 24-hour urine collection, the first void is discarded, and all subsequent urine should be saved. Choice A is incorrect because bowel movements do not contribute to a urine collection. Choice B indicates a single specimen rather than continuous collection over 24 hours. Choice D is incorrect as it incorrectly suggests rushing the test by drinking excessively.

Correct Answer: A

Rationale: The correct answer is A: Vitamin C and Zinc. Vitamin C is essential for collagen synthesis, which is important for wound healing. Zinc plays a crucial role in immune function and also aids in wound healing. Vitamin B12 and Calcium (Choice B) are not directly associated with wound healing properties. Vitamin D and Iron (Choice C) are important for overall health but are not specifically targeted for wound healing. Vitamin A and Potassium (Choice D) do not have direct wound healing properties and are not the best choices to promote wound healing and fight infection.
