A client in the hospital is receiving chemotherapy. Based on today’s blood laboratory results, which of the following actions should the nurse take?
- A. Check for hematuria
- B. Check for peaked T waves
- C. Obtain prescription for epoetin alfa
- D. Place a face mask on the client
Correct Answer: D
Rationale: Chemotherapy often causes neutropenia, increasing infection risk. A face mask (D) protects the client. Hematuria (A), peaked T waves (B), and epoetin (C) address other issues not directly indicated.
The nurse is assessing a comatose client receiving gastric tube feedings. Which of the following assessments requires an immediate response from the nurse?
- A. Decreased breath sounds in right lower lobe
- B. Aspiration of a residual of 100 cc of formula
Correct Answer: A
Rationale: Decreased breath sounds in the right lower lobe may indicate aspiration or pneumonia, a serious complication requiring immediate intervention to ensure airway patency and prevent further respiratory compromise.
A nurse is caring for a client 2 days after surgical creation of an arteriovenous fistula in the forearm. Which finding should the nurse report immediately to the health care provider?
- A. 2+ pitting edema of the extremity with the arteriovenous fistula
- B. Loud swooshing sound auscultated over the arteriovenous fistula
- C. Pale skin of the hand of the arm with the arteriovenous fistula
- D. Surgical site pain reported by the client as 3 on a scale of 0-10 during hand exercises
Correct Answer: C
Rationale: Pale skin in the hand (C) suggests vascular compromise, risking fistula failure or ischemia, requiring immediate reporting. Edema (A) is common, a swooshing sound (B) indicates patency, and mild pain (D) is expected.
Prior to administering a tube feeding, the nurse obtains 50 mL of aspirant. The nurse should:
- A. Discard the aspirant and begin the tube feeding.
- B. Replace the aspirant and begin the tube feeding.
- C. Discard the aspirant and hold the tube feeding.
- D. Replace the aspirant and hold the tube feeding.
Correct Answer: B
Rationale: Replacing the aspirant prevents fluid/electrolyte loss, and feeding can proceed if pH confirms placement. Discarding aspirant risks dehydration, and holding the feeding is unnecessary unless placement is uncertain.
A client in labor with a history of a previous cesarean birth has chosen to attempt a vaginal birth. During labor, which finding would be most concerning to the nurse?
- A. Cessation of contractions and maternal tachycardia
- B. Fetal tachycardia with moderate variability
- C. Increased anxiety and discomfort with contractions
- D. Painful, strong contractions every 3-4 minutes
Correct Answer: A
Rationale: Cessation of contractions with maternal tachycardia (A) suggests uterine rupture, a life-threatening emergency in VBAC due to scar dehiscence. Fetal tachycardia (B) is concerning but less specific, anxiety (C) is expected, and regular contractions (D) are normal.
