Nursing Elites

1. The client is being taught how to use a peak flow meter. The nurse explains that this device should be used to:

• A. Determine oxygen saturation
• B. Measure forced expiratory volume
• C. Monitor the atmosphere for the presence of allergens
• D. Provide metered doses for inhaled bronchodilator

Correct answer: B

Rationale: A peak flow meter is used to measure forced expiratory volume, which helps in monitoring asthma. This measurement provides valuable information about how well the client's lungs are functioning and how narrow their airways are. Choice A is incorrect because determining oxygen saturation is typically done using a pulse oximeter. Choice C is incorrect as a peak flow meter is not used to monitor the atmosphere for allergens but rather to assess lung function. Choice D is incorrect as providing metered doses for inhaled bronchodilators is the function of a metered-dose inhaler, not a peak flow meter.

2. Heparin 20,000 units in 500 ml D5W at 50 ml/hour has been infusing for 5.5 hours. How much heparin has the client received?

• A. 11,000 units.
• B. 13,000 units.
• C. 15,000 units.
• D. 17,000 units.

Correct answer: A

Rationale: To calculate the total amount of heparin received, multiply the infusion rate (50 ml/hour) by the total infusion time (5.5 hours). This results in 275 ml of the solution infused. Since there are 20,000 units of heparin in 500 ml, there are 800 units per ml. Therefore, 275 ml contains 220,000 units. However, the heparin is diluted in 500 ml, so the client has received half of this amount, which is 110,000 units. Therefore, the correct answer is 11,000 units. Choices B, C, and D are incorrect as they do not reflect the correct calculation based on the provided information.

3. The healthcare professional is caring for a client with a chest tube. What is the most important action for the healthcare professional to take to ensure the chest tube is functioning properly?

• A. Milk the chest tube to ensure patency.
• B. Clamp the chest tube when moving the client.
• C. Ensure the water seal chamber is filled to the appropriate level.
• D. Secure the chest tube to the client's bed.

Correct answer: C

Rationale: Ensuring the water seal chamber is filled to the appropriate level is crucial to maintain the effectiveness of the chest tube drainage system. This step helps prevent air from entering the pleural space, ensuring proper lung re-expansion. 'Milking' the chest tube is not recommended as it can cause damage to the chest tube and surrounding tissues. Clamping the chest tube is not advisable as it can lead to tension pneumothorax. Securing the chest tube to the bed is important for stability but does not directly impact the functioning of the chest tube.

4. A client with a history of falls is under the care of a nurse. Which of the following actions should be the nurse’s priority?

• A. Complete a fall-risk assessment.
• B. Educate the client and family about fall risks.
• C. Eliminate safety hazards from the client’s environment.
• D. Ensure the client uses assistive aids in their possession.

Correct answer: C

Rationale: The nurse's priority should be to eliminate safety hazards from the client's environment as it directly reduces the risk of falls. Addressing environmental hazards is an immediate and crucial step in preventing falls. While completing a fall-risk assessment is important to understand the client's risk factors, educating the client and family about fall risks is essential for prevention, and ensuring the use of assistive aids is crucial for safety, eliminating safety hazards takes precedence as it directly mitigates the risk of falls.

5. What advice should the client be given if they are feeling dizzy upon standing after taking a diuretic for hypertension?

• A. Avoid standing up too quickly.
• B. Increase fluid intake to stay hydrated.
• C. Eat more salt to help retain fluids.
• D. Wear compression stockings during the day.

Correct answer: A

Rationale: The correct advice for a client feeling dizzy upon standing after taking a diuretic for hypertension is to avoid standing up too quickly. Diuretics can lead to orthostatic hypotension, causing dizziness upon sudden position changes. Increasing fluid intake can exacerbate the issue by further lowering blood pressure. Eating more salt might counteract the diuretic's effects but is not the primary intervention for orthostatic hypotension. Compression stockings are more relevant for venous insufficiency than for orthostatic hypotension.
