Practice HESI Fundamentals Exam

Correct Answer: C

Rationale: Choice C is the correct answer because it demonstrates an understanding that soap and water should be used when hands are visibly dirty or when dealing with specific pathogens. Choice A is incorrect because it suggests the use of soap and water over alcohol-based hand rub without specifying the circumstances. Choice B is incorrect as it implies that using alcohol-based hand rub after using the restroom is always suitable. Choice D is incorrect because it states that hand rub is always enough, which is not true when hands are visibly soiled or when specific pathogens are present.

Correct Answer: A

Rationale: The correct answer is to use the complete name of the medication magnesium sulfate. This is important to prevent confusion with morphine sulfate, which is abbreviated as MSO4. Choice B is incorrect as it is essential to maintain a space between the numerical dose and the unit of measure for clarity in medication documentation. Choice C is incorrect as the standard abbreviation for units is 'U' for international units, not for the dosage of insulin. Choice D is incorrect as the appropriate abbreviation for subcutaneous injection is 'SC,' not just 'SC.' Therefore, the nurse manager should emphasize using the full name of medications to avoid errors and ensure patient safety.

Correct Answer: A

Rationale: Choice A is the most appropriate response as it acknowledges the client's feelings, showing empathy and understanding. It validates the client's experience, which can help reduce anxiety and build rapport. Choice B provides information but may not address the client's emotional needs. Choice C dismisses the client's concerns and does not offer support. Choice D minimizes the client's feelings and may not effectively address their anxiety.

Correct Answer: B

Rationale: The correct answer is B: Sodium polystyrene sulfonate (Kayexalate). Kayexalate is commonly used to lower potassium levels in clients with hyperkalemia by exchanging sodium ions for potassium ions in the large intestine, leading to the elimination of excess potassium from the body. Choice A, Furosemide (Lasix), is a loop diuretic that helps with fluid retention but does not directly lower potassium levels. Choice C, Calcium gluconate, is used to treat calcium deficiencies and does not impact potassium levels. Choice D, Albuterol (Proventil), is a bronchodilator used to treat respiratory conditions and does not affect potassium levels. Therefore, the LPN/LVN should anticipate the prescription of Kayexalate to address the client's hyperkalemia.

Correct Answer: C

Rationale: The second nurse should prepare a new syringe and administer the medication to ensure proper and timely pain management. Administering another nurse's medication without preparation could lead to errors. Choice A is not the priority as the medication administration should take precedence. Choice B is not recommended as the second nurse should not administer medication prepared by another nurse. Choice D is inappropriate as patient needs should not be compromised for medication administration to another client.
