HESI LPN
Community Health HESI Practice Exam
1. The nurse is assessing a client with chronic obstructive pulmonary disease (COPD). Which of the following findings should the nurse expect?
- A. Decreased anteroposterior diameter
- B. Hyperresonance on percussion
- C. Increased breath sounds
- D. Prolonged expiratory phase
Correct answer: D
Rationale: The correct answer is D: Prolonged expiratory phase. In COPD, there is airflow obstruction leading to difficulty in exhaling air. This results in a prolonged expiratory phase. Choices A, B, and C are incorrect. Decreased anteroposterior diameter is associated with conditions like barrel chest in emphysema, not COPD. Hyperresonance on percussion is typical in conditions like emphysema, not necessarily in COPD. Increased breath sounds are not a typical finding in COPD; instead, diminished breath sounds may be present due to air trapping.
2. In planning nursing care for a bedfast client, which factor is most likely to contribute to the development of deep vein thrombosis (DVT) in an immobile client?
- A. Atherosclerotic plaque formation.
- B. Stasis of blood flow.
- C. Endothelial damage.
- D. Atherosclerotic vessel changes.
Correct answer: B
Rationale: The correct answer is B: Stasis of blood flow. Stasis of blood flow in immobile clients increases the risk of DVT, as lack of movement can cause blood to pool and clot. Atherosclerotic plaque formation (choice A) and atherosclerotic vessel changes (choice D) are more related to arterial diseases rather than DVT. Endothelial damage (choice C) can contribute to the development of DVT, but in an immobile client, stasis of blood flow is the most significant factor.
3. When teaching a client about managing hypertension, what dietary advice should be emphasized?
- A. Reduce sodium intake
- B. Increase potassium intake
- C. Limit alcohol consumption
- D. All of the above
Correct answer: D
Rationale: When managing hypertension, it is crucial to adopt comprehensive dietary changes. This includes reducing sodium intake to help lower blood pressure, increasing potassium intake to counteract the effects of sodium and help regulate blood pressure, and limiting alcohol consumption as excessive alcohol can raise blood pressure. Therefore, emphasizing all the options provided (A, B, and C) is essential in effectively managing hypertension and reducing overall cardiovascular risk. Choices A, B, and C are not individually sufficient as a single dietary modification but collectively work together to support blood pressure management.
4. A community health nurse is conducting a home visit to assess a family's health needs. What is the first step in this process?
- A. Develop a care plan
- B. Conduct a physical examination
- C. Establish rapport with the family
- D. Provide health education
Correct answer: C
Rationale: Establishing rapport with the family is crucial in the initial stages of a home visit. It helps build trust, open communication channels, and allows the nurse to gain insight into the family's health needs and concerns. Developing a care plan (Choice A) comes after the assessment phase, where information is gathered. Conducting a physical examination (Choice B) is a part of the assessment but typically follows establishing rapport. Providing health education (Choice D) is important but usually occurs after the assessment and care planning stages.
5. The healthcare provider attaches a pulse oximeter to a client's fingers and obtains an oxygen saturation reading of 91%. Which assessment finding most likely contributes to this reading?
- A. BP 142/88 mmHg
- B. 2+ edema of fingers and hands
- C. Radial pulse volume is +3
- D. Capillary refill time is 2 seconds
Correct answer: B
Rationale: Edema, indicated by 2+ edema of fingers and hands, can impair blood flow and peripheral perfusion, leading to reduced oxygen saturation readings on a pulse oximeter. High blood pressure (choice A) would not directly affect oxygen saturation readings. Radial pulse volume (choice C) and capillary refill time (choice D) are more related to assessing circulation rather than contributing significantly to oxygen saturation readings.
