Nursing Elites

1. A healthcare professional is teaching a client about the use of a metered-dose inhaler (MDI). Which instruction should the professional include?

• A. Inhale for 1 second
• B. Shake the inhaler vigorously
• C. Hold the inhaler 5-7 cm away from the mouth
• D. Hold breath for 5 seconds after inhalation

Correct answer: B

Rationale: The correct instruction when using a metered-dose inhaler (MDI) is to shake the inhaler vigorously before use. Shaking the inhaler ensures proper mixing of the medication, which is crucial for effective delivery of the medication into the lungs. Inhaling for a specific duration, holding the inhaler at a certain distance from the mouth, or holding the breath after inhalation are not as critical as ensuring proper mixing of the medication by shaking the inhaler.

2. During a focused assessment for a client with dysrhythmias, what indicates ineffective cardiac contractions?

• A. Increased heart rate
• B. Pulse deficit
• C. Elevated blood pressure
• D. Bounding pulse

Correct answer: B

Rationale: A pulse deficit is a crucial finding in clients with dysrhythmias as it indicates ineffective cardiac contractions. A pulse deficit occurs when the apical heart rate is faster than the radial pulse rate, suggesting that some heartbeats are not generating a pulse. This can be a sign of serious heart conditions like atrial fibrillation or heart failure. The other options, such as an increased heart rate (choice A), elevated blood pressure (choice C), and bounding pulse (choice D), do not specifically indicate ineffective cardiac contractions and are not directly associated with dysrhythmias.

3. A client with chronic obstructive pulmonary disease (COPD) is being taught breathing exercises by a nurse. What instruction should the nurse include to improve oxygenation?

• A. Use pursed-lip breathing during activities
• B. Use deep breathing exercises after meals
• C. Perform diaphragmatic breathing during exercise
• D. Breathe in short, shallow breaths

Correct answer: A

Rationale: The correct instruction the nurse should include to improve oxygenation for a client with COPD is to 'Use pursed-lip breathing during activities.' Pursed-lip breathing helps improve oxygenation by slowing down the respiratory rate, reducing the work of breathing, and keeping the airways open. This technique also helps prevent the collapse of small airways during exhalation, allowing for more complete emptying of the lungs. Choices B, C, and D are incorrect because deep breathing exercises after meals, diaphragmatic breathing during exercise, and breathing in short, shallow breaths do not specifically target the improvement of oxygenation in individuals with COPD.

4. A nurse is assessing the IV infusion site of a client who reports pain at the site. The site is red, and there is warmth along the course of the vein. What is the nurse's priority action?

• A. Flush the IV line with saline
• B. Discontinue the infusion
• C. Elevate the limb
• D. Apply a cold compress

Correct answer: B

Rationale: The correct answer is to discontinue the infusion. The symptoms described - pain, redness, and warmth along the vein - are indicative of phlebitis, which is inflammation of the vein. Continuing the infusion can lead to further complications. Flushing the IV line, elevating the limb, or applying a cold compress do not address the underlying issue of phlebitis and may not be sufficient to resolve the problem. Therefore, the priority action is to discontinue the infusion to prevent worsening of the condition.

5. A nurse is preparing to perform a sterile dressing change for a client who has a surgical wound. What should the nurse do to prevent contamination?

• A. Wear non-sterile gloves
• B. Apply sterile gloves over non-sterile gloves
• C. Change gloves if the sterile solution splashes onto the sterile field
• D. Cover the sterile field with a sterile drape

Correct answer: C

Rationale: The correct answer is C. If sterile solution splashes onto the sterile field, it is considered contaminated. Changing gloves in this situation ensures that the sterility of the dressing change is maintained. Choice A is incorrect as non-sterile gloves would introduce contaminants. Choice B is incorrect as layering gloves can increase the risk of contamination. Choice D is incorrect as covering the sterile field with a sterile drape is not the appropriate action to take in response to contamination.
