1. 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.
2. A client just had a flexible bronchoscopy. Which of the following nursing actions is appropriate?
- A. Withhold food and liquids until the client's gag reflex returns.
- B. Irrigate the client's throat every 4 hours.
- C. Have the client refrain from talking for 24 hours.
- D. Suction the client's oropharynx frequently.
Correct answer: A
Rationale: After a flexible bronchoscopy, it is crucial to withhold food and liquids until the client's gag reflex returns to prevent aspiration. Irrigating the client's throat every 4 hours, having the client refrain from talking for 24 hours, and frequent suctioning of the oropharynx are not indicated post-bronchoscopy and may even pose risks to the client's recovery.
3. A healthcare professional is reviewing the arterial blood gas results for a client in the ICU who has kidney failure and determines the client has respiratory acidosis. Which of the following findings should the healthcare professional expect?
- A. Widened QRS complexes
- B. Hyperactive deep tendon reflexes
- C. Bounding peripheral pulses
- D. Warm, flushed skin
Correct answer: A
Rationale: Respiratory acidosis is a condition characterized by increased carbon dioxide levels in the blood, resulting in acidosis. One of the potential consequences of respiratory acidosis is the development of electrolyte imbalances, particularly hyperkalemia. Hyperkalemia can lead to cardiac conduction abnormalities, manifested as widened QRS complexes on an electrocardiogram (ECG). Therefore, in a client with respiratory acidosis, the healthcare professional should expect to find widened QRS complexes as a result of the associated hyperkalemia.
4. A client developed fat embolism syndrome (FES) following a fracture. Which of the following laboratory findings should the nurse expect?
- A. Decreased serum calcium level
- B. Decreased level of serum lipids
- C. Decreased erythrocyte sedimentation rate (ESR)
- D. Increased platelet count
Correct answer: A
Rationale: In fat embolism syndrome (FES), fat globules enter the bloodstream and can lead to various complications, including a decrease in serum calcium levels. This occurs due to the formation of fat emboli in the vessels, which can interfere with calcium metabolism. Therefore, a decreased serum calcium level is an expected laboratory finding in a client with fat embolism syndrome.
5. A healthcare professional is assessing a client who has a fracture of the femur. Vital signs are obtained on admission and again in 2 hours. Which of the following changes in assessment should indicate to the healthcare professional that the client could be developing a serious complication?
- A. Increased respiratory rate from 18 to 44/min
- B. Increased oral temperature from 36.6° C (97.8° F) to 37° C (98.6° F)
- C. Increased blood pressure from 112/68 to 120/72 mm Hg
- D. Increased heart rate from 68 to 72/min
Correct answer: A
Rationale: An increased respiratory rate from 18 to 44/min is a significant change that should alert the healthcare professional to a potential serious complication. Such a drastic increase in respiratory rate may indicate respiratory distress or hypoxia, which are critical conditions requiring immediate attention. The other options show minor changes in vital signs that are within normal limits and are less likely to indicate a serious complication.
