Extract:
Question 1 of 5
A 4-year-old admitted with Wilms tumor is scheduled for a right nephrectomy in the morning. Which nursing action is a priority pre-operatively?
Correct Answer: D
Rationale: Avoiding abdominal palpation (
D) prevents tumor rupture in Wilms tumor, a critical pre-operative priority. Emotional assessment (
A), lung sounds (
B), and BP monitoring (
C) are important but secondary.
Question 2 of 5
A client with chronic heart failure is being discharged home on furosemide and supplementary potassium chloride tablets. Which instructions related to the potassium supplement should the nurse reinforce to the client?
Correct Answer: D
Rationale: Potassium chloride tablets should be taken with water and the client should remain upright to prevent esophageal irritation or ulceration (

Question 3 of 5
Thirty-six hours after major surgery, a client has a temperature of 100°F. What is the most likely cause of the temperature elevation?
Correct Answer: B
Rationale: Atelectasis, due to reduced lung expansion post-surgery, is a common cause of low-grade fever within 24–48 hours. Dehydration, wound infection (typically later), or bladder infection are less likely without specific symptoms.
Question 4 of 5
A non-stress test has been ordered for a pregnant client with diabetes mellitus. Non-stress testing is a part of the diabetic's prenatal care because:
Correct Answer: C
Rationale: Diabetes can impair placental vessel development, reducing oxygen and nutrient delivery to the fetus, necessitating non-stress testing to monitor fetal well-being. Fetal movement and lung maturity are assessed differently, and insulin's effect is indirect.
Question 5 of 5
The nurse is caring for a client who has acute pericarditis. Which of the following findings would be a priority to follow up?
Correct Answer: B
Rationale: Muffled heart tones and jugular venous distension (
