ATI Detailed Answer Key Medical Surgical
1. While providing teaching to a client who is postoperative following coronary artery bypass graft (CABG) surgery and is receiving opioid medications to manage discomfort, which of the following desired effects of medications should the nurse identify as most important for the client's recovery?
- A. It decreases the client's level of anxiety.
- B. It facilitates the client's deep breathing.
- C. It enhances the client's ability to sleep.
- D. It reduces the client's blood pressure.
Correct answer: B
Rationale: In the postoperative period following CABG surgery, deep breathing exercises are essential to prevent complications such as atelectasis and pneumonia. Opioid medications can depress the respiratory system, making it crucial for the nurse to emphasize the importance of deep breathing to maintain optimal lung function. While managing pain and anxiety are important, facilitating deep breathing takes precedence in this situation to promote effective recovery and prevent respiratory complications.
2. When caring for a client with acute renal failure, which laboratory value is most important to monitor?
- A. Serum sodium
- B. Serum potassium
- C. Serum calcium
- D. Serum chloride
Correct answer: B
Rationale: In acute renal failure, monitoring serum potassium is crucial because impaired kidney function can lead to hyperkalemia, which can result in life-threatening cardiac dysrhythmias. Elevated potassium levels need close monitoring and prompt interventions to prevent serious complications.
3. A client presents with shortness of breath, pain in the lung area, and a recent history of starting birth control pills and smoking. Vital signs include a heart rate of 110/min, respiratory rate of 40/min, and blood pressure of 140/80 mm Hg. Arterial blood gases reveal pH 7.50, PaCO2 29 mm Hg, PaO2 60 mm Hg, HCO3 20 mEq/L, and SaO2 86%. What is the priority nursing intervention?
- A. Prepare for mechanical ventilation.
- B. Administer oxygen via face mask.
- C. Prepare to administer a sedative.
- D. Assess for indications of pulmonary embolism.
Correct answer: B
Rationale: In a client with a high respiratory rate, low PaO2, and low SaO2, the priority intervention is to improve oxygenation. Administering oxygen via a face mask will help increase the oxygen supply to the client's lungs and tissues, addressing the hypoxemia. While mechanical ventilation may be necessary in severe cases, administering oxygen is the initial and most appropriate intervention to address the client's respiratory distress. Sedatives should not be given without ensuring adequate oxygenation. Assessing for pulmonary embolism is important but not the priority at this moment when the client is experiencing respiratory distress and hypoxemia.
4. A nurse is caring for four hospitalized clients. Which of the following clients should the nurse identify as being at risk for fluid volume deficit?
- A. The client who has been NPO since midnight for endoscopy
- B. The client who has left-sided heart failure and has a brain natriuretic peptide (BNP) level of 600 pg/mL
- C. The client who has end-stage renal failure and is scheduled for dialysis today
- D. The client who has gastroenteritis and is febrile
Correct answer: D
Rationale: Gastroenteritis can lead to fluid loss through vomiting and diarrhea, especially when accompanied by fever. Fever can increase insensible water loss through sweating as well. Both vomiting and diarrhea can significantly contribute to fluid volume deficit, making the client with gastroenteritis and fever at higher risk compared to the other clients described in the options.
5. A client takes atorvastatin (Lipitor), with laboratory results showing a blood urea nitrogen (BUN) of 33 mg/dL and creatinine of 2.8 mg/dL. What action by the nurse is best?
- A. Ask if the client eats grapefruit.
- B. Assess the client for dehydration.
- C. Facilitate admission to the hospital.
- D. Obtain a random urinalysis.
Correct answer: A
Rationale: There is a drug-food interaction between statins and grapefruit that can lead to acute kidney failure. The client has elevated renal laboratory results, indicating kidney involvement. The nurse should ask if the client consumes grapefruit or grapefruit juice. While dehydration can elevate BUN, the increase in creatinine is more specific for kidney injury.
