1. When using a metered-dose inhaler (MDI), which step is most important for ensuring effective medication delivery?
- A. Exhale completely before using the inhaler
- B. Inhale quickly while pressing down on the inhaler
- C. Shake the inhaler for 10 seconds before use
- D. Hold breath for 5 seconds after inhaling
Correct answer: A
Rationale: The correct step to ensure effective medication delivery when using a metered-dose inhaler (MDI) is to exhale completely before using the inhaler. This action helps create more space in the lungs for the medication to reach deeply into the airways. Inhaling quickly while pressing down on the inhaler (Choice B) may cause the medication to impact the throat rather than reaching the lungs. Shaking the inhaler for 10 seconds before use (Choice C) is important to mix the medication but not the most crucial step for effective delivery. While holding the breath for 5 seconds after inhaling (Choice D) can help the medication stay in the lungs momentarily, exhaling completely before inhalation is more critical for optimal drug deposition.
2. A client with asthma is prescribed a corticosteroid inhaler. What instruction should the nurse give about the inhaler?
- A. Use it only during asthma attacks
- B. Rinse the mouth after each use to prevent oral thrush
- C. It will provide immediate relief during an asthma attack
- D. Increase the dose if breathing does not improve
Correct answer: B
Rationale: The correct instruction for a client using a corticosteroid inhaler is to rinse the mouth after each use to prevent the development of oral thrush, a common side effect of these inhalers. Choice A is incorrect as corticosteroid inhalers are often used regularly as a maintenance treatment, not just during asthma attacks. Choice C is incorrect because corticosteroid inhalers provide long-term control of asthma symptoms, not immediate relief during an attack. Choice D is incorrect and potentially dangerous advice as increasing the dose without medical guidance can lead to adverse effects.
3. The nurse is planning to ambulate a client who has been on bed rest for 24 hours following a Colon Resection. To ambulate this client safely, which intervention should the nurse implement first?
- A. Place non-skid shoes on the client
- B. Show the client how to use the call light
- C. Use a gait belt to support the client
- D. Assist the client to a bedside sitting position
Correct answer: D
Rationale: To ambulate a client safely after a period of bed rest, the nurse should first assist the client to a bedside sitting position. This initial step ensures the client is stable before attempting to stand and walk, reducing the risk of falls and allowing for a gradual adjustment to activity post-bed rest. Placing non-skid shoes, showing how to use the call light, or using a gait belt are important but should come after ensuring the client is safely seated and stable.
4. What is the primary purpose of a chest tube in a client's care?
- A. To drain air and fluid from the pleural space
- B. To prevent infection in the thoracic cavity
- C. To assist with lung expansion
- D. To monitor intrathoracic pressure
Correct answer: A
Rationale: The correct answer is A: To drain air and fluid from the pleural space. A chest tube is primarily used to remove accumulated air or fluid in the pleural space, preventing lung collapse or compromise of lung function. This intervention aims to re-expand the lung and enhance respiratory function. Choice B is incorrect because preventing infection is not the primary purpose of a chest tube. Choice C is incorrect as lung expansion is a result of draining the pleural space, not the primary goal. Choice D is incorrect as monitoring intrathoracic pressure is not the main objective of a chest tube insertion.
5. The healthcare provider reviews the laboratory results of a client whose serum pH is 7.38. What does this value imply about the client's homeostasis?
- A. Alkalosis
- B. Acidosis
- C. Normal serum pH
- D. Incompatible with life
Correct answer: C
Rationale: A pH of 7.38 falls within the normal range (7.35-7.45), indicating that the client’s acid-base balance is adequately maintained. Choices A and B are incorrect as alkalosis and acidosis refer to abnormal pH levels. Choice D is incorrect as a pH of 7.38 within the normal range is compatible with life.
