1. The healthcare provider is assessing a client who has a chest tube in place following a pneumothorax. Which finding should be reported to the healthcare provider immediately?
- A. Bubbling in the water seal chamber
- B. Drainage greater than 70 ml/hour
- C. Tidaling in the water seal chamber
- D. Absence of breath sounds on the affected side
Correct answer: D
Rationale: The absence of breath sounds on the affected side is a critical finding that may indicate a tension pneumothorax, a life-threatening condition requiring immediate intervention. This situation can lead to a shift of the mediastinum and impaired ventilation. Bubbling in the water seal chamber is an expected finding in a chest tube drainage system and indicates proper functioning. Drainage greater than 70 ml/hour is a concern but does not require immediate reporting unless it continues at a high rate or is associated with other symptoms. Tidaling in the water seal chamber is a normal fluctuation and indicates the chest tube system is patent and functioning correctly.
2. A healthcare professional is preparing to administer an intramuscular injection to a young adult client. Which of the following injection sites is the safest for this client?
- A. Ventrogluteal
- B. Dorsogluteal
- C. Deltoid
- D. Vastus lateralis
Correct answer: A
Rationale: The ventrogluteal site is considered the safest for intramuscular injections in young adult clients due to its location away from major nerves and blood vessels. The ventrogluteal site is preferred over the dorsogluteal site, as the latter is associated with a higher risk of injury to the sciatic nerve. The deltoid site is commonly used for vaccines but may not be suitable for all intramuscular injections due to smaller muscle mass. The vastus lateralis site is often used in infants and young children, but in young adults, the ventrogluteal site is preferred for safety and efficacy.
3. A client with peptic ulcer disease is prescribed sucralfate. What is the mechanism of action of this medication?
- A. Neutralizes stomach acid
- B. Decreases gastric acid secretion
- C. Covers the ulcer site and protects it from acid
- D. Improves gastric motility
Correct answer: C
Rationale: The correct answer is C: Covers the ulcer site and protects it from acid. Sucralfate works by forming a protective barrier over ulcers, shielding them from stomach acid and promoting healing. Choice A, neutralizing stomach acid, is incorrect as sucralfate does not neutralize acid but acts as a physical barrier. Choice B, decreasing gastric acid secretion, is not the mechanism of action of sucralfate. Choice D, improving gastric motility, is unrelated to sucralfate's action on peptic ulcers.
4. What is the primary purpose of performing range-of-motion (ROM) exercises?
- A. To improve cardiovascular fitness
- B. To prevent muscle atrophy and joint contractures
- C. To increase respiratory function
- D. To enhance cognitive function
Correct answer: B
Rationale: The primary purpose of performing range-of-motion (ROM) exercises is to prevent muscle atrophy and joint contractures. These exercises are crucial in maintaining joint mobility and muscle flexibility, especially in patients who are immobilized or have limited mobility. Improving cardiovascular fitness (Choice A) involves different types of exercises that target the heart and blood vessels, not specifically ROM exercises. Increasing respiratory function (Choice C) is typically achieved through breathing exercises and activities that enhance lung capacity. Enhancing cognitive function (Choice D) is usually addressed through cognitive exercises and activities that stimulate brain function.
5. A client who had an abdominal hysterectomy is experiencing minimal urine output despite adequate fluid intake. What should the nurse assess first?
- A. The client's bladder for distension.
- B. The IV catheter insertion site.
- C. The patency of the urinary catheter.
- D. The client's vital signs.
Correct answer: C
Rationale: Assessing the patency of the urinary catheter is crucial in this situation. A blocked catheter could be a common cause of decreased urine output following surgery. While checking the IV catheter insertion site (Choice B) is important, it is not the priority in this case. Examining the client's bladder for distension (Choice A) is relevant, but assessing the patency of the catheter takes precedence in resolving the issue of decreased urine output. Monitoring vital signs (Choice D) is a routine nursing task but not the priority when dealing with decreased urine output post-surgery.
