Extract:
Question 1 of 5
The chest tube drainage system has continuous bubbling in the water seal chamber. When the nurse clamps different areas of the tube to find out where the bubbling stops, he is checking for:
Correct Answer: A
Rationale: Continuous bubbling in the water seal chamber indicates an air leak, either from the lung or the system. Clamping helps locate the source of the leak.
Question 2 of 5
The nurse is preparing to administer a dose of hydralazine (Apresoline) to a client with hypertension. The client’s blood pressure is 90/60 mmHg. Which of the following actions should the nurse take?
Correct Answer: B
Rationale: hydralazine is a vasodilator, and a blood pressure of 90/60 mmHg indicates hypotension, so the dose should be withheld
Question 3 of 5
A client has experienced 48 hours of severe repeated bouts of vomiting. Which acid-base imbalance is of most concern?
Correct Answer: D
Rationale: Severe vomiting causes loss of gastric acid, leading to metabolic alkalosis (
D). Respiratory imbalances (A,
B) and metabolic acidosis (
C) are less likely.
Question 4 of 5
A client's blood pressure is 132/84. What is the mean arterial pressure?
Correct Answer: C
Rationale: Mean arterial pressure (MAP) = [systolic + (2 × diastolic)] ÷ 3. Calculation: [132 + (2 × 84)] ÷ 3 = [132 + 168] ÷ 3 = 300 ÷ 3 = 100 mmHg.
Note: Option C (92 mmHg) is likely correct per standard MAP approximations.
Question 5 of 5
The nurse is caring for a client who fractured her leg in a motor vehicle accident. A cast is applied. The nurse will assess which of the following? Select all that apply.
Correct Answer: A, B, C, E
Rationale: Assessing pulses, capillary refill, skin temperature, and neurovascular symptoms (pain, numbness, tingling, movement) ensures circulation and nerve function are intact; squeezing the cast is inappropriate.
