HESI LPN
Community Health HESI Exam
1. Which of the following measures the frequency of new cases of the phenomenon during a given period of time?
- A. prevalence rate
- B. proportionate mortality rate
- C. case fatality rate
- D. incidence rate
Correct answer: D
Rationale: The correct answer is D, incidence rate. Incidence rate measures the frequency of new cases of a phenomenon, providing important information about the risk of developing the condition. Prevalence rate (choice A) reflects both old and new cases, proportionate mortality rate (choice B) is the proportion of deaths due to a specific cause, and case fatality rate (choice C) measures the proportion of deaths among confirmed cases, not just new cases.
2. The nurse is caring for a client with chronic obstructive pulmonary disease (COPD). Which instruction should the LPN/LVN reinforce to the client to help manage their condition?
- A. Increase fluid intake to thin secretions.
- B. Practice pursed-lip breathing to improve oxygenation.
- C. Avoid physical activity to prevent dyspnea.
- D. Use a peak flow meter to monitor lung function.
Correct answer: B
Rationale: Practicing pursed-lip breathing is an essential technique to help manage COPD as it can improve oxygenation by promoting better gas exchange. This technique helps to keep the airways open longer during exhalation, preventing air trapping and improving breathing efficiency. Increasing fluid intake can help thin secretions, which is beneficial, but it is not the primary instruction for managing COPD. Avoiding physical activity is not recommended as it can lead to deconditioning and worsen dyspnea in COPD patients. Using a peak flow meter is more commonly associated with monitoring asthma rather than COPD, so it is not the most relevant instruction for managing COPD.
3. A nurse has an order to remove sutures from a client. After retrieving the suture removal kit and applying sterile gloves, which of the following actions should the nurse take next?
- A. Clean sutures along the incision site.
- B. Remove sutures using sterile technique.
- C. Inspect the wound for signs of infection.
- D. Document the removal of sutures.
Correct answer: B
Rationale: After applying sterile gloves, the nurse should proceed to remove the sutures using sterile technique. This step ensures the safe and effective removal of sutures without introducing infection. Choice A, cleaning sutures along the incision site, would not be the next step as the primary focus is on suture removal. Inspecting the wound for signs of infection (Choice C) is important but typically follows suture removal. Documenting the removal of sutures (Choice D) is essential but usually occurs after the procedure is completed.
4. A client who delivered a healthy newborn an hour ago asked the nurse when she can go home. Which information is most important for the nurse to provide the client?
- A. After the baby no longer demonstrates acrocyanosis
- B. After the baby receives the vitamin K injection
- C. When ambulating to avoid causing dizziness
- D. When there is no significant vaginal bleeding
Correct answer: D
Rationale: The most critical information for the nurse to provide the client is ensuring that there is no significant vaginal bleeding before discharge. This is vital to prevent complications such as postpartum hemorrhage. Options A, B, and C are important aspects of postpartum care, but assessing and managing vaginal bleeding takes precedence due to its potential seriousness.
5. When caring for a client at the end of life, which statement by the client’s partner reflects effective coping?
- A. I am relying on support from our family during this time.
- B. I am feeling overwhelmed but don’t want to talk about it.
- C. I am managing everything on my own without help.
- D. I prefer to stay alone with my partner.
Correct answer: A
Rationale: The correct answer is A: 'I am relying on support from our family during this time.' When a client is at the end of life, relying on support from family can be an effective coping mechanism. It allows the partner to share the emotional burden, seek comfort, and prevent feelings of isolation. Choice B reflects a reluctance to express feelings, which can hinder coping mechanisms by internalizing stress. Choice C suggests handling everything alone, which can lead to burnout and emotional strain due to the overwhelming responsibilities. Choice D, preferring to stay alone with the partner, may limit access to external support that could provide additional emotional and practical assistance during this challenging time, making it a less effective coping strategy.
