ATI Detailed Answer Key Medical Surgical
1. A client is 12 hours postoperative and has a chest tube to a disposable water-seal drainage system with suction. The healthcare provider should intervene for which of the following observations?
- A. Constant bubbling in the suction-control chamber
- B. Continuous bubbling in the water-seal chamber
- C. Bloody drainage in the collection chamber
- D. Fluid-level fluctuations in the water-seal chamber
Correct answer: B
Rationale: Continuous bubbling in the water-seal chamber indicates an air leak, which can compromise the system's integrity and affect the client's respiratory status. The other options are expected findings in a client with a chest tube drainage system: constant bubbling in the suction-control chamber indicates proper suction function, bloody drainage in the collection chamber is expected in the immediate postoperative period, and fluid-level fluctuations in the water-seal chamber demonstrate normal drainage and lung re-expansion.
2. 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.
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 client with asthma has developed viral pharyngitis. Which of the following findings should the nurse expect?
- A. Petechiae on the chest and abdomen
- B. WBC 16,000/mm3
- C. Negative throat culture
- D. Severe hyperemia of pharyngeal mucosa
Correct answer: C
Rationale: Viral pharyngitis is typically caused by a virus, not bacteria, so a negative throat culture is an expected finding. The presence of petechiae on the chest and abdomen (Choice A) is not a common manifestation of viral pharyngitis. Elevated WBC count (Choice B) is more indicative of a bacterial infection rather than a viral one. Severe hyperemia of the pharyngeal mucosa (Choice D) is a possible finding in pharyngitis but is not specific to viral pharyngitis.
5. A client is on intravenous heparin to treat a pulmonary embolism. The client's most recent partial thromboplastin time (PTT) was 25 seconds. What action should the nurse anticipate?
- A. Decrease the heparin rate.
- B. Increase the heparin rate.
- C. No change to the heparin rate.
- D. Stop the heparin; start warfarin (Coumadin).
Correct answer: B
Rationale: For clients on heparin therapy, a PTT value of 1.5 to 2.5 times the normal range is required to ensure therapeutic anticoagulation. The normal PTT range is 25 to 35 seconds. In this case, the client's PTT of 25 seconds falls below the therapeutic range, indicating that the heparin dose is insufficient. Therefore, the nurse should anticipate increasing the heparin rate to achieve the desired therapeutic effect.
