Nursing Elites

1. A client with pneumonia is receiving oxygen via nasal cannula at 2 L/min. What assessment finding indicates the need for further intervention?

• A. The client reports feeling short of breath.
• B. The client's oxygen saturation is 92%.
• C. The client's respiratory rate is 20 breaths per minute.
• D. The client is unable to complete sentences without pausing.

Correct answer: D

Rationale: The correct answer is D because the inability to complete sentences without pausing indicates respiratory distress and the need for immediate intervention. This finding suggests an increased work of breathing and inadequate oxygenation. Choices A, B, and C are not as urgent as choice D. Feeling short of breath (choice A) is expected in pneumonia but does not necessarily indicate the need for immediate intervention. An oxygen saturation of 92% (choice B) is slightly below the normal range but may not require immediate intervention. A respiratory rate of 20 breaths per minute (choice C) is within the normal range and does not signify an urgent need for intervention.

2. An adolescent client with intellectual disability refuses oral hygiene. A behavior modification program is recommended. Which reinforcement is best for the nurse to implement?

• A. Candy for successful oral hygiene tasks.
• B. Tokens for each successful oral hygiene task.
• C. Privilege restrictions for refusing oral hygiene tasks.
• D. Preferred activities or privileges for compliance.

Correct answer: D

Rationale: In this scenario, the best reinforcement for the nurse to implement is preferred activities or privileges for compliance. Positive reinforcement with privileges is effective in encouraging behavior change in adolescents, including those with intellectual disabilities. Choice A (Candy for successful oral hygiene tasks) may not be suitable as it involves providing a sugary reward, which contradicts the goal of oral hygiene. Choice B (Tokens for each successful oral hygiene task) could be effective but may not be as motivating as preferred activities or privileges. Choice C (Privilege restrictions for refusing oral hygiene tasks) focuses on negative reinforcement, which is not as effective as positive reinforcement in behavior modification.

3. The nurse is caring for a client with a suspected myocardial infarction (MI). Which laboratory test result is most indicative of a recent MI?

• A. Elevated troponin levels
• B. Increased white blood cell count
• C. Increased lactate dehydrogenase (LDH)
• D. Elevated C-reactive protein (CRP)

Correct answer: A

Rationale: Elevated troponin levels are the most specific and sensitive indicator of myocardial infarction. Troponin levels increase within hours of an MI and remain elevated for several days. White blood cell count, lactate dehydrogenase (LDH), and C-reactive protein (CRP) are not specific markers for MI. An increased white blood cell count may indicate inflammation or infection, increased LDH levels can be seen in various conditions like liver disease or muscle injury, and elevated CRP is a general marker of inflammation rather than specific to MI.

4. The healthcare provider prescribes an IV infusion of isoproterenol in D5W at 300 mcg/hour. How many ml/hour should the nurse set the pump to?

• A. 100 ml/hour
• B. 75 ml/hour
• C. 60 ml/hour
• D. 125 ml/hour

Correct answer: B

Rationale: To calculate the correct infusion rate, convert 300 mcg/hour to mg/hour (300 mcg = 0.3 mg). Since the IV solution is 1 mg in 250 ml, the rate is calculated as 0.3 mg/hour = 75 ml/hour. Therefore, the nurse should set the pump to 75 ml/hour. Choice A (100 ml/hour) is incorrect as it does not reflect the accurate calculation. Choice C (60 ml/hour) is incorrect as it is lower than the correct rate. Choice D (125 ml/hour) is incorrect as it is higher than the correct rate.

5. A client is diagnosed with tuberculosis and is placed on isoniazid (INH) and rifampin (Rifadin). The nurse should emphasize the importance of

• A. Daily use of a bronchodilator
• B. The importance of taking medication as prescribed
• C. Decreasing salt intake
• D. Avoidance of direct sunlight

Correct answer: B

Rationale: The correct answer is B: The importance of taking medication as prescribed. In the treatment of tuberculosis, adherence to the prescribed medication regimen is crucial to effectively manage the infection and prevent the development of drug resistance. Choices A, C, and D are incorrect because bronchodilators, salt intake, and sunlight exposure are not directly related to the treatment of tuberculosis with isoniazid and rifampin.
