1. A client with a history of chronic obstructive pulmonary disease (COPD) is admitted to the hospital. The client is experiencing difficulty breathing and is very anxious. The nurse notes that the client’s oxygen saturation is 88% on room air. Which action should the nurse implement first?
- A. Place the client in a high Fowler’s position
- B. Administer supplemental oxygen
- C. Perform a thorough respiratory assessment
- D. Start an IV infusion of normal saline
Correct answer: B
Rationale: Administering supplemental oxygen is the first priority to address low oxygen saturation and ease breathing. In a client with COPD experiencing difficulty breathing and anxiety with oxygen saturation at 88%, providing supplemental oxygen takes precedence over other actions. Placing the client in a high Fowler’s position may help with breathing but does not address the immediate need for increased oxygenation. Performing a thorough respiratory assessment is important but should come after stabilizing the client's oxygen levels. Starting an IV infusion of normal saline is not the priority in this situation and does not directly address the client's respiratory distress.
2. The healthcare provider prescribes potassium chloride 25 mEq in 500 ml D5W to infuse over 6 hours. The available 20 ml vial of potassium chloride is labeled '10 mEq/5 ml.' How many ml of potassium chloride should the nurse add to the IV fluid?
- A. 12.5
- B. 5
- C. 10
- D. 20
Correct answer: B
Rationale: To prepare 25 mEq of potassium chloride for the infusion, the nurse should add 5 ml of the 10 mEq/5 ml solution. This concentration provides the required amount of potassium chloride without exceeding the needed volume. Choice A would result in 12.5 mEq, which exceeds the prescribed amount. Choices C and D are incorrect as they do not align with the correct calculation based on the vial concentration.
3. Before leaving the room of a confused client, the nurse notes that a half bow knot was used to attach the client's wrist restraints to the movable portion of the client's bed frame. What action should the nurse take before leaving the room?
- A. Ensure that the knot can be quickly released.
- B. Tie the knot with a double turn or square knot.
- C. Move the ties so the restraints are secured to the side rails.
- D. Ensure that the restraints are snug against the client's wrist.
Correct answer: A
Rationale: The correct action for the nurse to take before leaving the room is to ensure that the knot can be quickly released. Using a half bow knot to attach the client's wrist restraints allows for quick release in case of an emergency. This is crucial for ensuring the safety of the client and complying with restraint policies. Tying the knot with a double turn or square knot (Choice B) would make it difficult to release quickly when needed. Moving the ties so the restraints are secured to the side rails (Choice C) does not address the immediate need for a quick release. Ensuring that the restraints are snug against the client's wrist (Choice D) may not be appropriate if the restraints need to be quickly removed for the client's safety.
4. The client who had a below-the-knee (BKA) amputation is being prepared for discharge to home. Which recommendation should the nurse provide this client?
- A. Inspect skin for redness
- B. Use a residual limb shrinker
- C. Apply alcohol to the stump after bathing
- D. Wash the stump with soap and water
Correct answer: D
Rationale: The correct recommendation for a client with a below-the-knee amputation preparing for discharge is to wash the stump with soap and water. This helps maintain cleanliness and prevent infection. Inspecting the skin for redness is important to monitor for signs of infection, but it is not a specific recommendation for a BKA amputation. Using a residual limb shrinker can aid in shaping and reducing swelling in the residual limb but is not usually done immediately after a BKA amputation. Applying alcohol to the stump after bathing is not recommended as it can lead to skin irritation and dryness.
5. Identify the placement of the stapes footplate into the bony labyrinth.
- A. Fenestra vestibuli
- B. Fenestra cochleae
- C. Tympanic membrane
- D. Round window
Correct answer: A
Rationale: The correct answer is A: Fenestra vestibuli. The stapes footplate is placed into the fenestra vestibuli of the bony labyrinth. This structure is also known as the oval window and is located at the junction of the middle ear and inner ear. Choice B, Fenestra cochleae, is incorrect as this opening is also known as the round window and is located near the base of the cochlea. Choice C, Tympanic membrane, is incorrect as it is also known as the eardrum and separates the external ear from the middle ear. Choice D, Round window, is incorrect as it is the opening covered by the secondary tympanic membrane and is important for the dissipation of sound waves in the cochlea.
