1. A client with cardiovascular disease is scheduled to receive a daily dose of furosemide (Lasix). Which potassium level would cause the nurse to contact the physician before administering the dose?
- A. 3.0 mEq/L
- B. 3.8 mEq/L
- C. 4.2 mEq/L
- D. 5.1 mEq/L
Correct answer: A
Rationale: The normal serum potassium level in adults ranges from 3.5 to 5.1 mEq/L. A potassium level of 3.0 mEq/L is low, indicating hypokalemia and necessitating physician notification before administering furosemide, a loop diuretic that can further lower potassium levels. Potassium levels of 3.8 and 4.2 mEq/L are within the normal range, while a level of 5.1 mEq/L is high (hyperkalemia), but the critical value in this case is the low potassium level that requires immediate attention to prevent potential complications.
2. The nurse is performing an admission assessment of an older client who has difficulty swallowing and has a history of aspiration pneumonia. Which action should the nurse implement first?
- A. Obtain a speech therapy consult
- B. Elevate the head of the bed
- C. Check the client's lung sounds
- D. Implement aspiration precautions
Correct answer: B
Rationale: The correct action for the nurse to implement first is to elevate the head of the bed. Elevating the head of the bed helps prevent aspiration in clients with swallowing difficulties by reducing the risk of food or fluids entering the airway. While obtaining a speech therapy consult (Choice A) is important, the immediate priority is to ensure the client's safety by positioning them properly. Checking the client's lung sounds (Choice C) and implementing aspiration precautions (Choice D) are also essential steps but should follow the immediate intervention of elevating the head of the bed to prevent aspiration.
3. Which assessment is most important for the nurse to include in the daily plan of care for a client with a burned extremity?
- A. Distal pulse intensity
- B. Skin integrity
- C. Pain levels
- D. Range of motion
Correct answer: A
Rationale: The correct answer is A: Distal pulse intensity. Monitoring distal pulses is crucial to ensure that circulation to the extremity is not compromised. This assessment helps in detecting any signs of decreased circulation, which is vital in managing a burned extremity. While skin integrity (choice B), pain levels (choice C), and range of motion (choice D) are also important assessments, monitoring distal pulse intensity takes precedence as it directly reflects the perfusion status of the affected extremity in a burned client.
4. The nurse is caring for a client with a chest tube. Which of these assessments is a priority?
- A. Assessing for subcutaneous emphysema
- B. Assessing for signs of infection at the insertion site
- C. Monitoring the client's respiratory status
- D. Checking the chest tube for kinks or occlusions
Correct answer: B
Rationale: Assessing for signs of infection at the insertion site is the priority when caring for a client with a chest tube. Infection at the insertion site can lead to serious complications such as empyema or sepsis. Monitoring respiratory status is essential but assessing for infection takes precedence to prevent immediate harm. Assessing for subcutaneous emphysema is important but not the priority unless it compromises respiratory function. Checking the chest tube for kinks or occlusions is crucial for proper drainage but is not the priority when infection is a concern.
5. A 56-year-old female client is receiving intracavitary radiation via a radium implant. Which nurse should be assigned to care for this client?
- A. A nurse who is pregnant.
- B. A nurse with Marfan syndrome who is postmenopausal.
- C. A nurse with a cold.
- D. A nurse who is lactating.
Correct answer: B
Rationale: A nurse with Marfan syndrome who is postmenopausal can safely care for the client because Marfan syndrome does not affect the ability to care for this client, and postmenopausal status minimizes the risk of radiation exposure affecting reproductive health. Choice A is incorrect because pregnancy increases the risk of radiation exposure to the fetus. Choice C is incorrect because a nurse with a cold may have a compromised immune system and should not be exposed to radiation therapy. Choice D is incorrect because lactation can increase the risk of radiation exposure to breast tissue.
