Question 1 of 5
Following a motor vehicle accident, a client with chest trauma receives a chest tube to relieve a hemothorax. Two hours following the chest tube insertion, the nurse observes the water level in the water-seal chamber is rising during inspiration and falling during expiration. Which action should the nurse implement?
Correct Answer: B
Rationale: Rising water levels during inspiration and falling during expiration, known as tidaling, indicate proper chest tube function, as it reflects pressure changes in the pleural space. Continuing to monitor the drainage system ensures ongoing assessment of drainage characteristics without disrupting the system unnecessarily.
Question 2 of 5
The healthcare provider prescribes regular insulin 10 units/hr IV. The IV solution contains 100 units of regular insulin in 100 mL of 0.9% normal saline. How many mL/hr should the nurse program the infusion pump? (Enter numerical value only.)
Correct Answer: 10 mL/hr
Rationale: The solution contains 1 unit/mL (100 units/100 mL). For a prescribed rate of 10 units/hr, the infusion pump should be set to deliver 10 mL/hr, as each mL provides 1 unit of insulin.
Question 3 of 5
A male adolescent arrives at the clinic and reports intense pain in the testicular area that occurred during football practice at high school. The nurse observes the scrotum and identifies significant erythema and swelling. Which action should the nurse take?
Correct Answer: D
Rationale: Sudden testicular pain and swelling suggest testicular torsion, a medical emergency requiring immediate provider notification for evaluation and possible surgery.
Question 4 of 5
The nurse is providing discharge instructions to the caregiver of an infant with recurrent otitis media. Which statement made by the caregiver should the nurse recognize as needing additional education about minimizing subsequent infections?
Correct Answer: A
Rationale: Benzocaine drops do not prevent otitis media and may cause harm. Other statements reflect correct preventive measures.
Question 5 of 5
A client experiences residual effects following an acute attack of Ménière's disease and receives a new prescription for an antihistamine. Which assessment finding indicates that the medication is effective?
