Nursing Elites

1. A client with a diagnosis of myocardial infarction (MI) is prescribed nitroglycerin. What is the primary action of this medication?

• A. Increases heart rate
• B. Lowers blood pressure
• C. Dilates coronary arteries
• D. Reduces myocardial oxygen demand

Correct answer: C

Rationale: The correct answer is C: Nitroglycerin dilates coronary arteries, improving blood flow to the heart muscle. This helps increase oxygen supply to the heart tissue. Option A, 'Increases heart rate,' is incorrect because nitroglycerin does not directly affect heart rate. Option B, 'Lowers blood pressure,' is also incorrect as while nitroglycerin can lower blood pressure, its primary action in the context of MI is related to coronary artery dilation. Option D, 'Reduces myocardial oxygen demand,' is not the primary action of nitroglycerin in the treatment of myocardial infarction; its main action is to increase oxygen supply by dilating coronary arteries.

2. The nurse is teaching a client with hypertension about lifestyle modifications. Which recommendation is most effective for lowering blood pressure?

• A. Increase intake of red meat
• B. Engage in regular physical activity
• C. Consume a high-sodium diet
• D. Limit fluid intake to 1 liter per day

Correct answer: B

Rationale: Engaging in regular physical activity is a highly effective recommendation for lowering blood pressure and improving overall cardiovascular health. Regular exercise helps to strengthen the heart, improve blood circulation, and manage weight, all of which contribute to reducing blood pressure levels. Choices A, C, and D are incorrect. Increasing intake of red meat can lead to higher saturated fat consumption, which is detrimental to heart health. Consuming a high-sodium diet can exacerbate hypertension by increasing blood pressure. Limiting fluid intake to 1 liter per day may lead to dehydration and is not a recommended approach for managing hypertension.

3. During a severe asthma exacerbation in a client, what is the nurse's priority?

• A. Administer a rescue inhaler immediately
• B. Prepare for intubation
• C. Encourage deep breathing exercises
• D. Monitor oxygen saturation levels

Correct answer: A

Rationale: During a severe asthma exacerbation, the nurse's priority is to administer a rescue inhaler immediately. This action helps open the airways and improve breathing, which is crucial in managing the exacerbation. Choice B, preparing for intubation, would be considered if the client's condition deteriorates and they are unable to maintain adequate oxygenation even after using the rescue inhaler. Encouraging deep breathing exercises (Choice C) may not be appropriate during a severe exacerbation as the client may struggle to breathe. While monitoring oxygen saturation levels (Choice D) is important, the immediate administration of a rescue inhaler takes precedence to address the acute breathing difficulty.

4. The healthcare provider is preparing to administer an IM injection to an adult client. Which site is the preferred location for this injection?

• A. Deltoid muscle
• B. Vastus lateralis muscle
• C. Ventrogluteal muscle
• D. Dorsogluteal muscle

Correct answer: C

Rationale: The ventrogluteal site is the preferred site for IM injections in adults due to its muscle mass and low risk of nerve injury. The deltoid muscle, although commonly used for vaccines in adults due to easy accessibility, has a smaller muscle mass making it less ideal for IM injections. The vastus lateralis muscle is typically used in infants and young children, not in adults. The dorsogluteal site has a higher risk of injury to the sciatic nerve and is no longer recommended for IM injections in any age group.

5. When caring for a client with a tracheostomy, what is the most important assessment to perform?

• A. Check the client's oxygen saturation
• B. Assess the tracheostomy site for signs of infection
• C. Monitor the client's respiratory rate
• D. Ensure the tracheostomy ties are secure

Correct answer: A

Rationale: The most important assessment to perform when caring for a client with a tracheostomy is to check the client's oxygen saturation. This assessment is crucial as it ensures that the client is receiving adequate oxygen through the tracheostomy. Monitoring oxygen saturation provides immediate information on the client's respiratory status and the effectiveness of the airway management. Assessing the tracheostomy site for signs of infection is important but not as critical as ensuring adequate oxygenation. Monitoring the respiratory rate is also essential but does not directly assess the effectiveness of oxygenation. Ensuring tracheostomy ties are secure is important for maintaining the device but does not directly evaluate the client's oxygenation status.
