Nursing Elites

1. When using a metered-dose inhaler (MDI), which step is most important for ensuring effective medication delivery?

• A. Exhale completely before using the inhaler
• B. Inhale quickly while pressing down on the inhaler
• C. Shake the inhaler for 10 seconds before use
• D. Hold breath for 5 seconds after inhaling

Correct answer: A

Rationale: The correct step to ensure effective medication delivery when using a metered-dose inhaler (MDI) is to exhale completely before using the inhaler. This action helps create more space in the lungs for the medication to reach deeply into the airways. Inhaling quickly while pressing down on the inhaler (Choice B) may cause the medication to impact the throat rather than reaching the lungs. Shaking the inhaler for 10 seconds before use (Choice C) is important to mix the medication but not the most crucial step for effective delivery. While holding the breath for 5 seconds after inhaling (Choice D) can help the medication stay in the lungs momentarily, exhaling completely before inhalation is more critical for optimal drug deposition.

2. The nurse is caring for a client 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: Administering morphine is a priority intervention during the acute phase of myocardial infarction (MI). Morphine not only provides pain relief but also reduces myocardial oxygen demand, which is crucial in this situation. Choice B is incorrect because isometric exercises can increase myocardial oxygen demand and are not recommended during the acute phase of MI. Choice C is incorrect as elevating the head of the bed, not keeping the client flat, is preferred to reduce workload on the heart. Choice D is incorrect because fluid intake should be encouraged unless contraindicated, as adequate hydration is essential for cardiac function.

3. Which intervention is most effective in preventing the spread of infection in a healthcare setting?

• A. Wearing gloves
• B. Using hand sanitizer
• C. Practicing hand hygiene
• D. Disinfecting surfaces

Correct answer: C

Rationale: Practicing hand hygiene is the most effective measure to prevent the spread of infection in healthcare settings. While wearing gloves, using hand sanitizer, and disinfecting surfaces are important infection control measures, they are not as effective as proper hand hygiene. Hand hygiene, including handwashing with soap and water or using alcohol-based hand sanitizers, is crucial in preventing the transmission of pathogens from one person to another, making it the best choice among the options provided. Wearing gloves primarily protects the wearer and is not a substitute for hand hygiene. Using hand sanitizer is helpful but may not be as effective as proper handwashing. Disinfecting surfaces is important but does not address the direct transmission of pathogens through hand contact, which hand hygiene effectively prevents.

4. A client requires application of an eye shield to the right eye. What should the nurse do in order to apply tape to anchor the shield most effectively?

• A. Place tape from the cheek to the forehead
• B. Secure tape from the nose to the ear
• C. Attach tape from the lower eyelid to the upper forehead
• D. Use circular bandaging around the head

Correct answer: C

Rationale: The correct way to apply tape to anchor an eye shield effectively is to attach the tape from the lower eyelid to the upper forehead. This method provides stability for the shield without putting pressure on the eye itself, thus helping to protect the eye. Choices A, B, and D are incorrect because taping from the cheek to the forehead, securing tape from the nose to the ear, or using circular bandaging around the head may not provide the necessary stability and protection required for the eye shield.

5. A client reports feeling anxious and having trouble sleeping lately. What non-pharmacological intervention should the nurse suggest first?

• A. Starting an exercise program
• B. Keeping a sleep diary
• C. Practicing relaxation techniques before bed
• D. Using sleep-inducing medications at night

Correct answer: C

Rationale: The correct non-pharmacological intervention the nurse should suggest first for a client experiencing anxiety and sleep issues is practicing relaxation techniques before bed. Relaxation techniques like deep breathing, progressive muscle relaxation, or mindfulness meditation can help reduce anxiety levels and promote better sleep naturally. Starting an exercise program (Choice A) can be beneficial but may not provide immediate relief for anxiety and sleep problems. Keeping a sleep diary (Choice B) can help identify patterns but does not directly address anxiety. Using sleep-inducing medications (Choice D) should be considered only after non-pharmacological interventions have been tried.
