1. Following surgical repair of a cleft palate, what should be used to prevent injury to the suture line?
- A. Straw
- B. Spoon
- C. Syringe
- D. Cup
Correct answer: D
Rationale: Following surgical repair of a cleft palate, a cup should be used to prevent injury to the suture line. Utensils such as straws, spoons, droppers, and syringes should be avoided as they can cause trauma to the surgical site. Using a cup reduces the risk of disrupting the sutures and promotes proper healing.
2. The nurse is caring for a client with a nasogastric tube. Which action should the nurse take to ensure proper functioning of the tube?
- A. Flush the tube with 50 mL of normal saline every 8 hours
- B. Clamp the tube when not in use
- C. Position the client in a supine position
- D. Verify tube placement by checking pH of gastric contents
Correct answer: D
Rationale: Verifying tube placement by checking the pH of gastric contents is crucial to ensure the nasogastric tube is correctly positioned in the stomach. This action helps prevent complications such as aspiration. Flushing the tube with normal saline every 8 hours is not necessary for ensuring proper functioning of the tube. Clamping the tube when not in use may lead to the build-up of gastric secretions and blockages. Positioning the client in a supine position is not directly related to ensuring the proper functioning of the nasogastric tube.
3. The settings on a client's synchronized intermittent mandatory ventilation (SIMV) are respiratory rate 12 breaths/minute, tidal volume at 600 mL, FiO2 35%, and positive end-expiratory pressure (PEEP) 5 cm H2O. Which assessment finding necessitates immediate intervention by the nurse?
- A. Bilateral crackles in the lung bases.
- B. Low-pressure indicator alarm.
- C. Oxygen saturation of 91%.
- D. Respiratory rate of 18 breaths/minute.
Correct answer: B
Rationale: A low-pressure alarm may indicate a disconnection or leak in the system, which needs immediate intervention. Bilateral crackles in the lung bases may indicate fluid overload but do not require immediate intervention in this case. An oxygen saturation of 91% is concerning but not as urgent as a potential equipment issue. A respiratory rate of 18 breaths/minute is higher than the set rate but may not necessitate immediate intervention unless accompanied by other distress symptoms.
4. A client who experienced partial-thickness burns with over 50% body surface area (BSA) 2 weeks ago suddenly becomes restless and agitated.
- A. Increase the room temperature.
- B. Assess the oxygen saturation.
- C. Continue to monitor vital signs.
- D. Notify the rapid response team.
Correct answer: D
Rationale: In a burn patient with sudden restlessness and agitation, it is crucial to consider hypoxia or other critical conditions. As such, notifying the rapid response team is the most appropriate action to ensure prompt assessment and intervention. Increasing room temperature (Choice A) is not the priority in this scenario. While monitoring vital signs (Choice C) is important, the sudden change in behavior warrants immediate action. Assessing oxygen saturation (Choice B) is a step in the right direction, but involving the rapid response team ensures a comprehensive evaluation and timely management of the patient's condition.
5. How are type IV hypersensitivity reactions different from all other types (I, II, or III) of hypersensitivity reactions?
- A. They involve antigen-antibody complexes.
- B. They are mediated by T cells and do not involve antibodies.
- C. They result in immediate allergic reactions.
- D. They are the least severe form of hypersensitivity.
Correct answer: B
Rationale: Type IV hypersensitivity reactions are mediated by T cells and cytokine release, leading to delayed reactions, unlike types I, II, and III, which involve antibodies. Choice A is incorrect because type IV reactions do not involve antigen-antibody complexes. Choice C is incorrect as type IV reactions do not result in immediate allergic reactions. Choice D is incorrect as type IV reactions are not the least severe form of hypersensitivity; in fact, they are known to cause significant tissue damage and inflammation.
