Nursing Elites

1. The client is diagnosed with pneumonia. Which intervention is most effective in promoting airway clearance?

• A. Administer bronchodilators as prescribed
• B. Encourage increased fluid intake
• C. Perform chest physiotherapy
• D. Provide humidified oxygen

Correct answer: B

Rationale: Encouraging increased fluid intake is the most effective intervention in promoting airway clearance for a client with pneumonia. Increasing fluid intake helps to thin respiratory secretions, making it easier for the client to clear the airways. Administering bronchodilators may help with bronchospasm but does not directly promote airway clearance. Chest physiotherapy may be beneficial but is not the first-line intervention for promoting airway clearance in pneumonia. Providing humidified oxygen can improve oxygenation but does not directly address airway clearance.

2. A 9-year-old is receiving vancomycin 400 mg IV every 6 hours for a methicillin-resistant (Beta-lactam-resistant) Staphylococci aureus (MRSA) infection. The medication is diluted in a 100 mL bag of saline with instructions to infuse over one and a half hours. How many mL/hour should the nurse program the infusion pump?

• A. 50
• B. 67
• C. 57
• D. 70

Correct answer: B

Rationale: To calculate the infusion rate for vancomycin, you need to divide the total volume by the total time of infusion. In this case, the total volume is 100 mL, and the total time is 1.5 hours. Therefore, 100 mL ÷ 1.5 hours = 67 mL/hour. This means the nurse should program the infusion pump to deliver vancomycin at a rate of 67 mL/hour. Choice A (50) is incorrect as it does not reflect the correct calculation. Choice C (57) is incorrect as it is not the accurate calculation based on the provided information. Choice D (70) is incorrect as it does not correspond to the correct infusion rate calculation.

3. A client is admitted with a diagnosis of myocardial infarction (MI). Which intervention is a priority during the acute phase?

• A. Administer morphine for pain relief
• B. Encourage the client to perform isometric exercises
• C. Position the client flat in bed
• D. Restrict fluid intake

Correct answer: A

Rationale: During the acute phase of a myocardial infarction (MI), the priority intervention is to administer morphine for pain relief. Morphine not only alleviates pain but also reduces myocardial oxygen demand, which is crucial in the management of MI. Encouraging the client to perform isometric exercises (choice B) can increase myocardial oxygen demand and should be avoided during the acute phase. Positioning the client flat in bed (choice C) may worsen symptoms by increasing venous return and workload on the heart. Restricting fluid intake (choice D) is not a priority intervention during the acute phase of MI; maintaining adequate hydration is important for organ perfusion.

4. The nurse is preparing to administer a subcutaneous injection of heparin. What is the correct angle of insertion?

• A. 15 degrees
• B. 30 degrees
• C. 45 degrees
• D. 90 degrees

Correct answer: C

Rationale: The correct angle of insertion for a subcutaneous injection, such as heparin, is 45 degrees. This angle is appropriate as it helps to ensure proper delivery of the medication into the subcutaneous tissue. Option A (15 degrees) is too shallow for a subcutaneous injection and may result in the medication being deposited into the muscle. Option B (30 degrees) is also too shallow for subcutaneous injections. Option D (90 degrees) is used for intramuscular injections, not subcutaneous injections.

5. A client with a diagnosis of rheumatoid arthritis is prescribed methotrexate. What is the primary action of this medication?

• A. Increases joint lubrication
• B. Reduces inflammation by suppressing the immune system
• C. Enhances bone density
• D. Stimulates cartilage regeneration

Correct answer: B

Rationale: The correct answer is B: Methotrexate is an immunosuppressant that works by suppressing the immune system, thereby reducing inflammation in rheumatoid arthritis. Methotrexate does not directly increase joint lubrication (Choice A) as its primary action is on the immune system. Choices C and D are incorrect since methotrexate does not enhance bone density or stimulate cartilage regeneration. It is crucial for healthcare providers to understand the mechanism of action of medications to provide safe and effective care to patients.
