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 caring for a client who underwent a total knee replacement yesterday. What activity level should the nurse encourage today?
- A. Bed rest with bathroom privileges only
- B. Frequent, short walks with assistance
- C. Range of motion exercises to the knee every four hours
- D. Leg elevation to reduce swelling
Correct answer: B
Rationale: After a total knee replacement, early ambulation is crucial for promoting circulation and preventing complications like thrombosis. Bed rest should be avoided as it can increase the risk of complications. Range of motion exercises are important but should be performed gradually and not excessively. Leg elevation is beneficial for reducing swelling but should not be the primary activity level encouraged immediately after surgery.
3. The nurse is monitoring a client who started taking a new medication for rheumatoid arthritis. What is the most important aspect to monitor?
- A. Signs of gastrointestinal bleeding
- B. Liver function tests
- C. Renal function tests
- D. All necessary monitoring based on the medication prescribed
Correct answer: D
Rationale: When a client starts a new medication for rheumatoid arthritis, it is crucial to monitor all necessary aspects based on the specific medication prescribed. Different medications can have varying side effects and impacts on different organ systems. Monitoring all relevant parameters ensures the early detection of any adverse effects and helps to maintain the client's safety. While monitoring for signs of gastrointestinal bleeding, liver function tests, and renal function tests are all important in certain situations, the priority is to conduct comprehensive monitoring based on the medication's known effects.
4. During a community health fair, a nurse is providing education on the effects of smoking. What is the most important information to include?
- A. Smoking can lead to cosmetic issues like tooth staining.
- B. Smoking is a leading cause of preventable death worldwide.
- C. Smoking temporarily elevates mood and alertness.
- D. Smoking is an expensive habit.
Correct answer: B
Rationale: The correct answer is B: 'Smoking is a leading cause of preventable death worldwide.' This information is crucial as it highlights the severe health risks associated with smoking, emphasizing the importance of cessation for overall health. Choice A is incorrect because cosmetic issues like tooth staining are not as significant as the life-threatening consequences of smoking. Choice C is incorrect because although smoking may temporarily elevate mood and alertness due to nicotine, this does not outweigh the serious health implications. Choice D is incorrect as while smoking is indeed an expensive habit, the focus should be on the health-related consequences to stress the urgency of quitting.
5. During a manic episode, what is the most appropriate intervention to implement first for a client with bipolar disorder?
- A. Engage the client in a quiet activity
- B. Provide a structured environment with minimal stimulation
- C. Monitor the client continuously
- D. Adjust the lighting and noise levels
Correct answer: B
Rationale: During a manic episode, individuals with bipolar disorder may experience sensory overload and agitation. Providing a structured environment with minimal stimulation is the most appropriate initial intervention as it can help reduce overwhelming sensory input and promote a sense of calm. Engaging the client in a quiet activity (Choice A) may not be effective if the environment is still overstimulating. Continuous monitoring (Choice C) is important but may not be the first intervention needed. Adjusting lighting and noise levels (Choice D) can be helpful but may not address the core issue of sensory overload and agitation during a manic episode.
