Nursing Elites

1. How many ounces are in 1 cup?

• A. 8
• B. 80
• C. 800
• D. 8000

Correct answer: A

Rationale: 1 cup is equivalent to 8 ounces. This conversion is commonly used in cooking and baking recipes, where precise measurements are crucial for the successful outcome of dishes. Knowing this conversion helps ensure that ingredients are accurately measured and the recipe turns out as intended. Choices B, C, and D are incorrect because they do not reflect the correct conversion between cups and ounces. 80, 800, and 8000 ounces are significantly higher quantities than what is found in 1 cup, which is 8 ounces.

2. Which of the following white blood cell (WBC) counts clearly indicates leukocytosis?

• A. 4,500/mm³
• B. 7,000/mm³
• C. 10,000/mm³
• D. 25,000/mm³

Correct answer: D

Rationale: Leukocytosis is defined as an increase in the total white blood cell count. A normal WBC count typically ranges from 4,500 to 10,000/mm³. A WBC count of 25,000/mm³, as indicated in choice D, is significantly higher than the normal range and clearly indicates leukocytosis.

3. In the emergency department, a nurse is assessing a client involved in a motor vehicle crash. Findings include absent breath sounds in the left lower lobe with dyspnea, blood pressure 118/68 mm Hg, heart rate 124/min, respirations 38/min, temperature 38.6 C (101.4 F), and SaO2 92% on room air. What action should the nurse take first?

• A. Obtain a chest X-ray.
• B. Prepare for chest tube insertion.
• C. Administer oxygen via high-flow mask.
• D. Initiate IV access.

Correct answer: C

Rationale: In this scenario, the client is presenting with signs of respiratory distress, including absent breath sounds, dyspnea, and a low SaO2 level. The priority action should be to improve oxygenation by administering oxygen via a high-flow mask. This intervention aims to increase the oxygen supply to the client's lungs, helping to address the hypoxemia. Once oxygenation is optimized, further interventions, such as obtaining a chest X-ray, preparing for chest tube insertion, or initiating IV access, can be considered based on the client's condition and healthcare provider's orders.

4. A client is being educated by a healthcare provider on the purpose of taking a bronchodilator. Which of the following client statements indicates an understanding of the teaching?

• A. ''This medication can decrease my immune response.''
• B. ''I take this medication to prevent asthma attacks.''
• C. ''I need to take this medication with food.''
• D. ''This medication has a slow onset to treat my symptoms.''

Correct answer: B

Rationale: The correct answer is, 'I take this medication to prevent asthma attacks.' Bronchodilators are commonly used to relieve bronchospasm in conditions such as asthma. This medication helps to dilate the airways, making it easier to breathe and preventing asthma attacks. The other options are incorrect: option A is inaccurate as bronchodilators do not decrease immune responses, option C is incorrect as bronchodilators are typically taken on an empty stomach for better absorption, and option D is false as bronchodilators have a rapid onset to provide quick relief of symptoms.

5. What is the appropriate needle gauge for intradermal injection?

• A. 20G
• B. 22G
• C. 25G
• D. 26G

Correct answer: D

Rationale: Intradermal injections require a very fine needle to be used to deliver the medication into the dermis layer of the skin. A 26G needle is typically used for intradermal injections as it is thin enough to penetrate the skin's surface and deposit the medication accurately.
