HESI Medical Surgical Practice Quiz
1. Blood for arterial blood gas determinations is drawn from a client with pneumonia, and testing reveals a pH of 7.45, PCO2 of 30 mm Hg, and HCO3 of 19 mEq/L. The nurse interprets these results as indicative of:
- A. Compensated metabolic acidosis
- B. Compensated respiratory alkalosis
- C. Uncompensated metabolic alkalosis
- D. Uncompensated respiratory acidosis
Correct answer: B
Rationale: The correct answer is 'Compensated respiratory alkalosis.' In this case, the client's pH is within the normal range (7.35-7.45), indicating compensation. The low PCO2 (30 mm Hg) suggests respiratory alkalosis, while the low HCO3 (19 mEq/L) is also consistent with a compensatory response. Therefore, the client has a primary respiratory alkalosis that is being compensated for by metabolic acidosis. Choices A, C, and D are incorrect because they do not fit the pattern of the given blood gas values, which indicate respiratory alkalosis with metabolic compensation.
2. Which of the following is a primary intervention for a patient with sepsis?
- A. Administering antibiotics
- B. Administering IV fluids
- C. Administering antipyretics
- D. Monitoring blood cultures
Correct answer: D
Rationale: Monitoring blood cultures is a primary intervention for a patient with sepsis because it helps identify the causative organism, which is crucial in guiding appropriate antibiotic therapy. Administering antibiotics (Choice A) is important in treating sepsis but is considered a secondary intervention. Administering IV fluids (Choice B) is also crucial for sepsis management to restore perfusion and hemodynamic stability. Administering antipyretics (Choice C) may help reduce fever, but it is not a primary intervention for managing sepsis.
3. A 58-year-old client who has been post-menopausal for five years is concerned about the risk for osteoporosis because her mother has the condition. Which information should the nurse offer?
- A. Osteoporosis is a progressive genetic disease with no effective treatment.
- B. Calcium loss from bones can be slowed by increasing calcium intake and exercise.
- C. Estrogen replacement therapy should be started to prevent the progression of osteoporosis.
- D. Low-dose corticosteroid treatment effectively halts the course of osteoporosis.
Correct answer: B
Rationale: Post-menopausal females are at risk for osteoporosis due to the cessation of estrogen secretion. While genetics can play a role, osteoporosis is not solely a genetic disease. Increasing calcium intake, along with vitamin D supplementation and weight-bearing exercise, can help prevent further bone loss by slowing down calcium loss from bones. Estrogen replacement therapy is no longer recommended as a first-line treatment for osteoporosis due to associated risks. Corticosteroid treatment is not typically used as a primary treatment for osteoporosis.
4. A male client with chronic kidney disease (CKD) is refusing to take his medication and has missed two hemodialysis appointments. What is the best initial action for the nurse?
- A. Discuss what the treatment regimen means to him.
- B. Refer the client to a mental health nurse practitioner.
- C. Reschedule the appointments to another date and time.
- D. Discuss the option of peritoneal dialysis.
Correct answer: A
Rationale: The best initial action for the nurse in this scenario is to have a discussion with the client about what the treatment regimen means to him. It is important to assess the client's anxiety, coping styles, and acceptance of the required treatment for CKD. The client may be in denial of the diagnosis or may have concerns that need to be addressed. While rescheduling hemodialysis appointments could be helpful, referring the client to a mental health nurse practitioner or discussing peritoneal dialysis are not the most appropriate first steps. Understanding the client's perspective and concerns is crucial before exploring other interventions.
5. A client has just had a central line catheter placed that is specific for hemodialysis. What is the most appropriate action by the nurse?
- A. Use the catheter for the next laboratory blood draw.
- B. Monitor the central venous pressure through this line.
- C. Access the line for the next intravenous medication.
- D. Place a heparin or heparin/saline dwell after hemodialysis.
Correct answer: D
Rationale: The most appropriate action for the nurse after a central line catheter placement for hemodialysis is to place a heparin or heparin/saline dwell after hemodialysis treatment. This helps prevent clot formation in the line and maintain patency for future use. Using the catheter for blood draws is not recommended as it may increase the risk of infection. Monitoring central venous pressure is not indicated with this type of catheter. Accessing the line for medications is also not recommended to prevent complications and ensure the line is solely used for hemodialysis purposes.
