HESI LPN
Adult Health 2 Final Exam
1. The practical nurse is preparing to administer a prescription for cefazolin (Kefzol) 600 mg IM every six hours. The available vial is labeled, 'Cefazolin (Kefzol) 1 gram,' and the instructions for reconstitution state, 'For IM use add 2 ml sterile water for injection. Total volume after reconstitution = 2.5 ml.' When reconstituted, how many milligrams are in each milliliter of solution?
- A. 400 mg/mL
- B. 500 mg/mL
- C. 450 mg/mL
- D. 350 mg/mL
Correct answer: A
Rationale: After reconstitution, the concentration of cefazolin solution is calculated by dividing the total amount of drug (600 mg) by the total volume after reconstitution (2.5 mL). This gives 600 mg / 2.5 mL = 240 mg/mL. However, the question asks for the concentration in each milliliter of solution after reconstitution, so we need to consider the final volume of 2.5 mL. Therefore, 240 mg/mL * 2.5 mL = 600 mg, which means each milliliter contains 240 mg of cefazolin. Therefore, after reconstitution, there are 400 mg of cefazolin in each milliliter of solution. Choices B, C, and D are incorrect as they do not accurately reflect the concentration after reconstitution.
2. The nurse is preparing a client for discharge after a major surgical procedure. What is the priority instruction to include in the discharge teaching?
- A. Signs of infection to monitor for
- B. Pain management techniques
- C. Activity restrictions and safety measures
- D. All of the above
Correct answer: D
Rationale: The correct answer is D: All of the above. Providing comprehensive discharge instructions covering signs of infection to monitor for, pain management techniques, activity restrictions, and safety measures is crucial after a major surgical procedure. Each of these components plays a vital role in the client's recovery and well-being. It is important for the client to understand how to identify signs of infection, manage pain effectively, and adhere to activity restrictions to prevent complications and ensure a smooth recovery process. While each instruction is important on its own, combining all aspects into the discharge teaching ensures that the client has a holistic understanding of their post-operative care, empowering them to take charge of their health and know when to seek further assistance if needed. Choices A, B, and C are essential components of discharge teaching and should all be included to provide the client with comprehensive care instructions.
3. A client with a history of hypertension is prescribed hydrochlorothiazide (HCTZ). Which adverse effect should the nurse monitor for?
- A. Hyperkalemia
- B. Hyponatremia
- C. Bradycardia
- D. Hyperglycemia
Correct answer: B
Rationale: The correct answer is 'B. Hyponatremia.' Hydrochlorothiazide can lead to electrolyte imbalances, such as hyponatremia, due to its diuretic effect. This potential adverse effect should be closely monitored in patients taking HCTZ. Choice A, hyperkalemia, is less likely to occur with HCTZ as it tends to cause hypokalemia. Choice C, bradycardia, is not a common adverse effect of HCTZ. Choice D, hyperglycemia, is also less commonly associated with HCTZ use compared to hyponatremia.
4. Based on the documentation in the medical record, which action should the nurse implement next?
- A. Administer the rubella vaccine subcutaneously
- B. Observe the mother breastfeeding her infant
- C. Call the nursery for the infant's blood type result
- D. Administer Vicodin one tablet for pain
Correct answer: B
Rationale: The correct answer is to observe the mother breastfeeding her infant. This action is essential to ensure that the infant is feeding well and to assess maternal-infant bonding. Administering the rubella vaccine subcutaneously (Option A) is not the immediate priority in this scenario as assessing breastfeeding is more crucial. Calling the nursery for the infant's blood type result (Option C) is premature and not the next appropriate step, as it does not address the immediate needs of the newborn. Administering Vicodin one tablet for pain (Option D) is not indicated without further assessment or indication of pain, making it an incorrect choice at this time.
5. The healthcare provider prescribes erythromycin (Ilosone) 300 mg PO QID. The medication label reads, 'Ilosone 100mg/5mL.' How many mL should the nurse administer at each dose?
- A. 15 mL
- B. 10 mL
- C. 20 mL
- D. 5 mL
Correct answer: A
Rationale: To determine the volume of medication needed for a 300 mg dose of Ilosone (100mg/5mL), we set up a proportion: 100 mg is to 5 mL as 300 mg is to x mL. Cross-multiplying, we get x = (300*5)/100 = 15 mL. Therefore, the nurse should administer 15 mL at each dose. Choice B (10 mL) is incorrect as it does not reflect the correct calculation based on the medication concentration. Choices C (20 mL) and D (5 mL) are also incorrect as they do not accurately calculate the volume required for the prescribed dose.
