HESI RN
HESI Fundamentals Practice Exam
1. Warm compresses are ordered for an open wound. Which action is appropriate for the nurse?
- A. Use sterile technique when applying the compresses.
- B. Leave the compresses on the area continuously, pouring warm solution on the area when it cools down.
- C. Alternate warm compresses with cold compresses.
- D. Apply a wet dressing and cover it with a dry dressing.
Correct answer: A
Rationale: Using sterile technique when applying the compresses is crucial to prevent infection and promote wound healing. Ensuring a clean environment during wound care reduces the risk of introducing pathogens that can lead to complications. Proper infection control measures play a significant role in the healing process of open wounds. Choice B is incorrect because leaving the compresses on continuously can lead to skin damage or thermal injury. Choice C is incorrect as alternating warm compresses with cold compresses is not appropriate for an open wound. Choice D is incorrect as applying a wet dressing without following specific orders can be detrimental to wound healing.
2. The healthcare provider is caring for a client with hyperparathyroidism. Which laboratory result requires immediate intervention?
- A. Serum calcium of 11 mg/dL.
- B. Serum phosphorus of 3 mg/dL.
- C. Serum magnesium of 1.8 mg/dL.
- D. Serum albumin of 4 g/dL.
Correct answer: A
Rationale: A serum calcium level of 11 mg/dL indicates hypercalcemia, which can be a complication of hyperparathyroidism and requires immediate intervention. Hypercalcemia can lead to serious complications such as cardiac dysrhythmias, renal failure, and neurologic symptoms. Monitoring and managing serum calcium levels are crucial in clients with hyperparathyroidism. Serum phosphorus, magnesium, and albumin levels are important to assess in clients with hyperparathyroidism, but they do not require immediate intervention as hypercalcemia poses a more urgent risk.
3. In a patient with chronic kidney disease, which of the following lab values would be expected?
- A. Elevated creatinine levels.
- B. Low hemoglobin levels.
- C. Elevated potassium levels.
- D. Low sodium levels.
Correct answer: A
Rationale: In chronic kidney disease, elevated creatinine levels are expected due to impaired kidney function. Creatinine is a waste product that is typically filtered out by the kidneys. With kidney disease, the clearance of creatinine is reduced, leading to its accumulation in the blood. Low hemoglobin levels (choice B) may be seen in chronic kidney disease due to decreased production of erythropoietin. However, elevated potassium levels (choice C) and low sodium levels (choice D) are more commonly associated with kidney dysfunction but are not as specific indicators of chronic kidney disease as elevated creatinine levels.
4. A nurse is conducting an assessment of a client who underwent thoracentesis of the right side of the chest 3 hours ago. Which findings does the nurse report to the physician? Select all that apply.
- A. Unequal chest expansion
- B. Pulse rate of 82 beats/min
- C. Respiratory rate of 22 breaths/min
- D. Diminished breath sounds in the right lung
Correct answer: A
Rationale: After thoracentesis, the nurse should assess the client for signs of pneumothorax, which include increased respiratory rate, dyspnea, retractions, unequal chest expansion, diminished breath sounds, and cyanosis. Unequal chest expansion is a key sign of pneumothorax due to the accumulation of air in the pleural space, causing the affected lung to collapse partially. Pulse rate and respiratory rate within normal ranges, like in choices B and C, are not the priority findings to report in this situation. Diminished breath sounds in the right lung could be expected after thoracentesis and may not necessarily indicate a complication like pneumothorax, making choice D less urgent to report.
5. The client with peripheral vascular disease (PVD) and a history of heart failure may have a low tolerance for exercise due to:
- A. Decreased blood flow.
- B. Increased blood flow.
- C. Decreased pain.
- D. Increased blood viscosity.
Correct answer: A
Rationale: The correct answer is A: Decreased blood flow. In clients with peripheral vascular disease (PVD) and a history of heart failure, decreased blood flow due to heart failure can result in reduced oxygen delivery to tissues. This reduced oxygen supply can lead to low exercise tolerance. Increased blood flow (Choice B) is not typically associated with reduced exercise tolerance in these clients. Decreased pain (Choice C) and increased blood viscosity (Choice D) are not the primary factors contributing to low exercise tolerance in this scenario.
