HESI Practice Test for Fundamentals

Correct Answer: B

Rationale: The LPN should monitor potassium levels closely while the client is taking furosemide (Lasix) due to the medication's potential to cause hypokalemia. Furosemide is a loop diuretic that can lead to potassium loss through increased urine output. Hypokalemia can result in serious complications such as cardiac dysrhythmias. Monitoring sodium levels (choice A) is important but not as critical as monitoring potassium in this context. Calcium (choice C) and magnesium (choice D) levels are not typically affected by furosemide and are not the priority for monitoring in this scenario.

Correct Answer: C

Rationale: When considering the use of complementary healing practices, it is important to acknowledge that many of these practices can be safely integrated with conventional treatments to provide holistic care. Choice A is incorrect because complementary healing practices can complement traditional medical approaches rather than interfere with their efficacy. Choice B is incorrect as interactions between conventional medications and folk remedies may vary, but not all interactions lead to adverse effects. Choice D is incorrect as conventional medical practices and complementary healing practices can coexist and each offer benefits in healthcare.

Correct Answer: A

Rationale: The correct answer is A: Temperature. A high fever is a significant indicator of infection or other serious conditions, making it the priority finding. Elevated temperature indicates an immediate concern for infection, which can quickly escalate and lead to severe complications if not addressed promptly. While heart rate, abdominal tenderness, and census overdue are important aspects to consider in the client's care, addressing the fever takes precedence due to its potential severity and implications for the client's health.

Correct Answer: D

Rationale: The correct answer is D, 'Glucose 45 mg/dL.' Glucose level of 45 mg/dL indicates hypoglycemia, which is a critical condition requiring immediate attention to prevent complications like seizures, loss of consciousness, and even coma. Hypoglycemia can lead to serious adverse outcomes if not promptly addressed. Choices A, B, and C do not represent immediate life-threatening conditions and can be managed as part of routine care, unlike hypoglycemia which demands urgent intervention.

Correct Answer: A

Rationale: Taking an iron supplement with milk can decrease its absorption, indicating a need for further teaching.
