Fundamentals HESI
1. The healthcare provider prescribes furosemide (Lasix) 15 mg IV stat. On hand is Lasix 20 mg/2 ml. How many milliliters should the LPN/LVN administer?
- A. 1 ml.
- B. 1.5 ml.
- C. 1.75 ml.
- D. 2 ml.
Correct answer: B
Rationale: To calculate the correct dose of 15 mg, the LPN/LVN should administer 1.5 ml of Lasix (20 mg/2 ml). This calculation ensures precise dosing. Choice A (1 ml) is too low and would provide only 10 mg, while choice C (1.75 ml) and choice D (2 ml) would exceed the prescribed dose, resulting in potential adverse effects. It is important for the LPN/LVN to administer the exact prescribed dose to ensure therapeutic efficacy and avoid unnecessary complications.
2. A nurse is preparing to review medication documentation with a group of newly licensed nurses. Which of the following statements should the nurse manager plan to include in the teaching?
- A. Use the complete name of the medication magnesium sulfate
- B. Maintain the space between the numerical dose and the unit of measure
- C. Note the dosage of insulin in units
- D. Use 'subcut' for indicating a subcutaneous injection
Correct answer: A
Rationale: The correct answer is A. The Institute for Safe Medication Practices recommends using the complete medication name magnesium sulfate when documenting medications to prevent misinterpretation. Choice B is incorrect because spaces should be maintained between the numerical dose and unit of measure for clarity. Choice C is incorrect as the standard notation for insulin dosage is in units, not using the letter U. Choice D is incorrect as the abbreviation for subcutaneous injection is commonly written as 'subcut' or 'subcutaneous,' not as SC.
3. The healthcare professional is preparing to administer a tuberculin skin test. Which site is most appropriate for this injection?
- A. Deltoid muscle
- B. Vastus lateralis muscle
- C. Abdomen
- D. Inner forearm
Correct answer: D
Rationale: The inner forearm is the most appropriate site for administering a tuberculin skin test. This test requires an intradermal injection, which is administered just below the surface of the skin. The inner forearm provides a flat, easily accessible surface for this type of injection. Choices A, B, and C are incorrect because the tuberculin skin test should not be administered into a muscle (deltoid muscle or vastus lateralis muscle) or into the abdomen. The test requires precise placement within the dermal layer of the skin on the inner forearm to accurately assess for a reaction.
4. A client who has been experiencing frequent tonic-clonic seizures is being admitted by a nurse. Which of the following actions should the nurse include in the client's plan of care?
- A. Wrap blankets around all four sides of the bed.
- B. Place the client in a padded room.
- C. Maintain the bed in the lowest position.
- D. Ensure the client has a soft mattress.
Correct answer: C
Rationale: Maintaining the bed in the lowest position is crucial in reducing the risk of injury during tonic-clonic seizures. This action helps prevent falls and minimizes potential harm to the client. Wrapping blankets around all four sides of the bed (Choice A) may restrict movement during a seizure and increase the risk of injury. Placing the client in a padded room (Choice B) is not a practical approach in a healthcare setting and may not be feasible. Ensuring the client has a soft mattress (Choice D) alone does not address the safety concerns during seizures, unlike keeping the bed in the lowest position.
5. A client has a prescription for 5 units of regular insulin and 10 units of NPH insulin to mix together and administer subcutaneously. Determine the correct order of steps for this procedure.
- A. Inject 5 units of air into the bottle of regular insulin
- B. Withdraw the correct dose of NPH insulin from the bottle
- C. Inject 10 units of air into the bottle of NPH insulin
- D. Withdraw the correct dose of regular insulin from the bottle
Correct answer: B
Rationale: The correct order of steps for this procedure is to first inject air into the NPH insulin bottle to prevent vacuum formation. After injecting air into the NPH insulin, the next step is to withdraw the correct dose of regular insulin from its bottle. This sequence ensures that the regular insulin is drawn after the NPH insulin, preventing contamination and ensuring accurate dosing. Therefore, choice B is correct. Choices A, C, and D are incorrect because air should be injected into the NPH insulin first, not the regular insulin, and the doses should be withdrawn in the appropriate order to maintain the integrity and potency of each insulin type.
