Nursing Elites

1. Which of the following are key parameters that produce blood pressure? (Select ONE that does not apply)

• A. Heart rate
• B. Stroke volume
• C. Peripheral resistance
• D. Neuroendocrine hormones

Correct answer: D

Rationale: Heart rate, stroke volume, and peripheral resistance are indeed key parameters that directly influence blood pressure. Heart rate refers to the number of times the heart beats per minute, affecting how much blood is pumped. Stroke volume is the amount of blood pumped by the heart in one contraction. Peripheral resistance is the resistance of the arteries to blood flow, impacting the pressure needed to push blood through. Neuroendocrine hormones, while they can indirectly influence blood pressure regulation by affecting factors like blood volume and vascular tone, are not direct final parameters that produce blood pressure.

2. The nurse is caring for a client with a tracheostomy who is on mechanical ventilation. What is the priority nursing intervention?

• A. Suction the tracheostomy as needed
• B. Ensure the tracheostomy ties are secure
• C. Provide humidified oxygen
• D. Clean any exudate around the tracheostomy site

Correct answer: A

Rationale: The priority nursing intervention for a client with a tracheostomy on mechanical ventilation is to suction the tracheostomy as needed. Suctioning is essential to maintain a clear airway and prevent respiratory distress. While ensuring tracheostomy ties are secure (choice B) is important, it is not as urgent as airway maintenance. Providing humidified oxygen (choice C) is beneficial but does not address the immediate need for airway clearance. Cleaning exudate around the tracheostomy site (choice D) is important for hygiene but takes precedence over ensuring airway patency through suctioning.

3. 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.

4. A nurse in a pediatric unit is preparing to administer medication to a child. What should the nurse do to ensure the correct dosage?

• A. Check the child's weight
• B. Verify the medication order with a pharmacist
• C. Consult the child's parents
• D. Double-check the dosage calculations with another nurse

Correct answer: D

Rationale: When administering medication to children, it is crucial to ensure the correct dosage to prevent dosing errors. Double-checking the dosage calculations with another nurse can help verify the accuracy of the prescribed dose, reducing the risk of medication errors. While checking the child's weight (Choice A) is important for dosage calculation, it alone may not ensure the correctness of the dosage. Verifying the medication order with a pharmacist (Choice B) is essential, but it may not directly address the accuracy of dosage calculations. Consulting the child's parents (Choice C) is not a standard practice for verifying medication dosages and should not be solely relied upon for ensuring the correct dosage.

5. The nurse is caring for a client with cirrhosis of the liver. Which clinical finding is most concerning?

• A. Jaundice.
• B. Ascites.
• C. Spider angiomas.
• D. Asterixis.

Correct answer: D

Rationale: The correct answer is D, Asterixis. Asterixis, also known as liver flap, is a sign of hepatic encephalopathy, a severe complication of liver disease that necessitates immediate attention. While jaundice (choice A), ascites (choice B), and spider angiomas (choice C) are common clinical findings in cirrhosis, asterixis is the most concerning due to its association with hepatic encephalopathy, which can lead to altered mental status and even coma. Jaundice, ascites, and spider angiomas are also important signs in cirrhosis, but asterixis indicates a more critical condition requiring urgent intervention.
