A client with a history of rheumatoid arthritis is prescribed methotrexate. Which laboratory value should the nurse monitor closely?
- A. Liver function tests
- B. Complete blood count
- C. Serum creatinine
- D. Prothrombin time
Correct Answer: C
Rationale: Serum creatinine should be closely monitored in a client receiving methotrexate, as the medication can cause nephrotoxicity. Monitoring serum creatinine levels helps assess kidney function and detect potential nephrotoxic effects of methotrexate. Liver function tests (Choice A) are important to monitor for hepatotoxicity caused by methotrexate. While methotrexate can cause bone marrow suppression, leading to anemia, leukopenia, and thrombocytopenia, monitoring a complete blood count (Choice B) is essential but not the priority in this case. Prothrombin time (Choice D) is not typically affected by methotrexate therapy and is not the primary laboratory value to monitor in this situation.

The nurse is assessing a client with chronic kidney disease (CKD) who is receiving erythropoietin therapy. Which laboratory value should be closely monitored?
- A. Serum potassium level
- B. Hemoglobin level
- C. White blood cell count
- D. Serum sodium level of 135 mEq/L
Correct Answer: A
Rationale: The correct answer is A: Serum potassium level. In clients receiving erythropoietin therapy for chronic kidney disease, monitoring serum potassium levels is crucial due to the risk of developing hyperkalemia. Erythropoietin therapy can stimulate red blood cell production, leading to an increase in potassium levels. Monitoring potassium levels helps prevent complications associated with hyperkalemia, such as cardiac arrhythmias. Choices B, C, and D are incorrect because while hemoglobin levels are relevant for assessing the effectiveness of erythropoietin therapy, monitoring potassium levels is more critical due to the potential adverse effects of elevated potassium levels in CKD patients on this therapy.
The nurse is caring for a client with a tracheostomy who has thick, tenacious secretions. Which assessment finding is most concerning?
- A. Crepitus around the tracheostomy site
- B. Dry and cracked tracheostomy site
- C. Yellowing of the skin around the tracheostomy site
- D. Mucous plugging of the tracheostomy tube
Correct Answer: D
Rationale: Mucous plugging of the tracheostomy tube is the most concerning finding in a client with a tracheostomy and thick secretions. This can lead to airway obstruction, which requires immediate intervention to maintain a patent airway. Crepitus around the tracheostomy site may indicate subcutaneous emphysema but does not pose an immediate threat to the airway. A dry and cracked tracheostomy site may require interventions to promote healing but is not as urgent as mucous plugging. Yellowing of the skin around the tracheostomy site could indicate infection or impaired circulation, which should be addressed but does not pose the same immediate risk as airway obstruction.
Before a dressing change to his legs, which intervention is most important for the nurse to implement?
- A. Encourage the patient to stay at the bedside
- B. Use distraction techniques to reduce pain
- C. Maintain strict aseptic technique
- D. Place a drape over the burn area
Correct Answer: C
Rationale: Maintaining strict aseptic technique is crucial before a dressing change for burn patients to prevent infection. Encouraging the patient to stay at the bedside, using distraction techniques, or placing a drape over the burn area are not as critical as ensuring asepsis in this situation.
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.
What is the most important instruction for the nurse to provide a client being discharged following treatment for Guillain-Barre syndrome?
- A. Avoid exposure to respiratory infections.
- B. Use relaxation exercises when anxious.
- C. Continue physical therapy at home.
- D. Plan short, frequent rest periods.
Correct Answer: A
Rationale: The most critical instruction for a client being discharged following treatment for Guillain-Barre syndrome is to avoid exposure to respiratory infections. Guillain-Barre syndrome can affect the respiratory system, making infections particularly dangerous. While relaxation exercises, physical therapy, and rest periods are beneficial for overall well-being and recovery, preventing respiratory infections takes precedence due to the potential life-threatening complications associated with respiratory compromise in Guillain-Barre syndrome.
