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. After administering pantoprazole to a client with gastroesophageal reflux disease (GERD), which statement by the client indicates to the nurse that the medication is producing the desired effect?
- A. After eating my meal, I did not experience any heartburn
- B. I have a great appetite and am feeling really hungry
- C. I should increase the amount of vitamin C in my diet
- D. While eating, I had no difficulty swallowing any of the foods
Correct answer: A
Rationale: The correct answer is A. Pantoprazole reduces stomach acid production, thus preventing the occurrence of heartburn after meals, which is a common symptom of GERD. Choice B is incorrect because an increased appetite and hunger are not indicators of the desired effect of pantoprazole. Choice C is unrelated to the medication's effect on GERD symptoms. Choice D is also incorrect because the absence of difficulty swallowing is not a specific indicator of pantoprazole's effectiveness in treating GERD.
3. What role does a community health nurse play in disaster management?
- A. Providing direct patient care
- B. Conducting research on disaster impacts
- C. Coordinating emergency response efforts
- D. Developing new healthcare policies
Correct answer: C
Rationale: Community health nurses are primarily responsible for coordinating emergency response efforts during disasters. This involves organizing and implementing strategies to address the health needs of the community in crisis situations. Providing direct patient care (Choice A) is often carried out by other healthcare professionals such as doctors and paramedics during disasters. Conducting research on disaster impacts (Choice B) is important for understanding the effects of disasters but is not the primary role of a community health nurse. Developing new healthcare policies (Choice D) is typically the responsibility of policymakers and public health officials rather than community health nurses.
4. The nurse plans to help an 18-year-old female intellectually disabled client ambulate on the first postoperative day after an appendectomy. When the nurse tells the client it is time to get out of bed, the client becomes angry and tells the nurse, 'Get out of here! I'll get up when I'm ready!' Which response is best for the nurse to make?
- A. Your healthcare provider has prescribed ambulation on the first postoperative day.
- B. You must ambulate to avoid complications that could cause more discomfort than ambulating.
- C. I know how you feel. You're angry about having to ambulate, but this will help you get well.
- D. I'll be back in 30 minutes to help you get out of bed and walk around the room.
Correct answer: D
Rationale: (D) provides a 'cooling off' period, is firm, direct, non-threatening, and avoids arguing with the client. (A) is avoiding responsibility by referring to the healthcare provider. (B) is trying to reason with an intellectually disabled client and is threatening the client with 'complications.' (C) is telling the client how she feels (angry), and the nurse does not really 'know' how this client feels, unless the nurse is also intellectually disabled and has also just had an appendectomy.
5. The nurse is providing care for a client with a draining postoperative wound infected with methicillin-resistant Staphylococcus aureus (MRSA). Which is the most important action for the nurse to take?
- A. Encourage increased oral fluids.
- B. Provide high-protein snacks.
- C. Change the wound dressing.
- D. Administer prescribed antibiotics.
Correct answer: D
Rationale: Administering prescribed antibiotics is crucial in treating MRSA infections. MRSA is a type of bacteria that is resistant to many antibiotics, including methicillin. Therefore, prompt administration of the appropriate antibiotics is essential to target the MRSA infection effectively. Encouraging increased oral fluids (Choice A) and providing high-protein snacks (Choice B) may be beneficial for overall recovery but are not the most important actions in treating an MRSA infection. Changing the wound dressing (Choice C) is important for wound care but does not directly address the infection caused by MRSA.
