HESI Fundamentals Exam

Correct Answer: C

Rationale: The correct answer is C: Identifying the client's medication allergies. This is the priority action before administering any medication to prevent allergic reactions or adverse effects. Teaching the client about the medication's purpose is important for client understanding but not as critical as ensuring the absence of allergies. While giving medication at the prescribed time is crucial, verifying allergies takes precedence to ensure patient safety. Documenting the client's anxiety level is relevant for holistic care but is not the priority compared to ensuring safe medication administration.

Correct Answer: D

Rationale: The correct answer is D. Rewarding school achievements with a point system rather than food items like pizza or ice cream is a healthier approach. This choice indicates an understanding of the teaching about nutrition and the importance of not using food as a reward. Choices A, B, and C do not demonstrate a clear understanding of the teaching as they focus on concerns about overeating, skipping meals, and limiting fast-food consumption but do not address the concept of avoiding food rewards for achievements.

Correct Answer: C

Rationale: The correct answer is C. Ensuring the oxygen equipment's wires and cables are in good working order is crucial to prevent sparks in an oxygen-rich environment, which could lead to a fire. Choices A, B, and D are incorrect because smoking near an oxygen tank, using a cotton blanket near oxygen (as cotton is less likely to generate static electricity than wool), and laying the oxygen tank down on the floor pose significant safety risks and are not appropriate practices for managing oxygen therapy at home.

Correct Answer: D

Rationale: In acute pancreatitis, hypocalcemia (low serum calcium) is a critical finding that is associated with a poor prognosis and requires immediate attention. Serum amylase and lipase are typically elevated in acute pancreatitis due to pancreatic inflammation, but they are not indicators of severity. Blood glucose levels may be elevated due to stress or underlying conditions but are not directly related to the severity of acute pancreatitis. Therefore, the most concerning value in this scenario is the low serum calcium level, which can have significant implications for the client's prognosis.

Correct Answer: A

Rationale: To calculate the mL to administer, use the formula: Dose required (mg) � Stock concentration (mg/mL) = Volume to administer (mL). In this case, 10 mg � 40 mg/mL = 0.25 mL. However, when rounding to the nearest tenth, the answer should be 0.3 mL. Therefore, the nurse should administer 0.3 mL. Choice A is the correct answer. Choice B (0.25 mL) is the result obtained before rounding. Choice C (0.4 mL) and Choice D (0.5 mL) are incorrect calculations.
