1. Mr. Landon is scheduled to undergo a tracheostomy. Which nursing action is essential during tracheal suctioning?
- A. Using a water-soluble lubricant.
- B. Administering 100% oxygen before and after suctioning.
- C. Ensuring that the suction catheter is open during insertion.
- D. Assisting the client to assume a semi-Fowler's position during suctioning.
Correct answer: B
Rationale: Administering 100% oxygen before and after suctioning is crucial to prevent hypoxia, which can occur during tracheal suctioning. Hypoxia can lead to serious complications, making the provision of oxygen essential in maintaining adequate oxygenation levels for the patient undergoing tracheal suctioning. Choice A is incorrect because using a water-soluble lubricant is not directly related to the essential nursing action during tracheal suctioning. Choice C is incorrect as ensuring that the suction catheter is open during insertion is a basic requirement and not the essential action for oxygenation. Choice D is incorrect because assisting the client to assume a semi-Fowler's position is beneficial for comfort and airway alignment but is not as crucial as administering oxygen to prevent hypoxia.
2. The healthcare provider is providing wound care to a client with a stage 3 pressure ulcer that has a large amount of eschar. The wound care prescription states 'clean the wound and then apply collagenase.' Collagenase is a debriding agent. The prescription does not specify a cleaning method. Which technique should the healthcare provider use to cleanse the pressure ulcer?
- A. Lightly coat the wound with povidone-iodine solution
- B. Irrigate the wound with sterile normal saline
- C. Flush the wound with sterile hydrogen peroxide
- D. Remove the eschar with a wet-to-dry dressing
Correct answer: B
Rationale: The correct technique to cleanse a wound when the prescription does not specify a cleaning method is to irrigate the wound with sterile normal saline. Sterile normal saline is the preferred solution for wound cleaning as it is gentle and does not damage healthy tissues. It helps in removing debris and maintaining a moist environment conducive to healing. Povidone-iodine solution and hydrogen peroxide can be harsh on tissues and delay wound healing. Removing eschar with a wet-to-dry dressing is a mechanical debridement method and should not be done without proper assessment and healthcare provider's order.
3. The client is weak from inactivity due to a 2-week hospitalization. In planning care for the client, which range of motion (ROM) exercises should the nurse include?
- A. Passive ROM exercises to all joints on all extremities four times a day.
- B. Active ROM exercises to both arms and legs two or three times a day.
- C. Active ROM exercises with weights twice a day, 20 repetitions each.
- D. Passive ROM exercises to the point of resistance and slightly beyond.
Correct answer: B
Rationale: Active ROM exercises are preferred over passive ROM to restore strength. Performing them on both arms and legs two or three times a day is effective in promoting muscle strength and mobility without the need for external assistance. Choice A is incorrect as passive ROM exercises may not help in restoring strength. Choice C is not recommended as using weights may be too strenuous for a weak client. Choice D is incorrect as passive ROM exercises to the point of resistance and slightly beyond may cause discomfort or injury to the weak client.
4. While suctioning a client’s nasopharynx, the nurse observes that the client’s oxygen saturation remains at 94%, which is the same reading obtained prior to starting the procedure. What action should the nurse take in response to this finding?
- A. Complete the intermittent suction of the nasopharynx.
- B. Reposition the pulse oximeter clip to obtain a new reading.
- C. Stop suctioning until the pulse oximeter reading is above 95%.
- D. Apply an oxygen mask over the client’s nose and mouth.
Correct answer: A
Rationale: A stable oxygen saturation reading of 94% indicates that the nurse can continue with the suctioning procedure. It is within an acceptable range, and there is no immediate need to interrupt the procedure. Continuing with the suctioning will help maintain airway patency and promote adequate oxygenation. Choice B is incorrect because repositioning the pulse oximeter clip is unnecessary when the reading is stable. Choice C is incorrect as there is no evidence to support stopping the suctioning procedure solely based on the oxygen saturation reading of 94%. Choice D is not the best action at this point, as applying an oxygen mask is not indicated when the oxygen saturation is stable and within an acceptable range.
5. When assessing a male client, the nurse finds that he is fatigued and experiencing muscle weakness, leg cramps, and cardiac dysrhythmias. Based on these findings, the nurse plans to check the client’s laboratory values to validate the existence of which condition?
- A. Hyperphosphatemia
- B. Hypocalcemia
- C. Hypermagnesemia
- D. Hypokalemia
Correct answer: D
Rationale: The symptoms of fatigue, muscle weakness, leg cramps, and cardiac dysrhythmias are classic manifestations of hypokalemia. Potassium plays a vital role in muscle function and cardiac conduction, so a deficiency can lead to these symptoms. Checking the client’s laboratory values for potassium levels will help confirm the presence of hypokalemia.
