Nursing Elites

1. The client is on nitroglycerin and reports chest pain. What is the nurse’s priority action?

• A. Administer nitroglycerin as ordered.
• B. Administer morphine as ordered.
• C. Administer aspirin as ordered.
• D. Notify the healthcare provider immediately.

Correct answer: D

Rationale: The correct answer is D: Notify the healthcare provider immediately. If a client on nitroglycerin reports chest pain, the priority action is to notify the healthcare provider immediately. This is crucial to ensure prompt reassessment of the client's condition and treatment plan. Administering nitroglycerin, morphine, or aspirin without consulting the healthcare provider first can be risky as the chest pain may indicate a need for a change in treatment or further evaluation. Administering medications without proper assessment and guidance can lead to complications and is not recommended in this scenario.

2. The nurse is caring for a client on warfarin with an INR of 1.8. What is the most appropriate action?

• A. Increase the dose of warfarin.
• B. Administer vitamin K.
• C. Hold the warfarin and notify the healthcare provider.
• D. Monitor the client’s INR closely.

Correct answer: D

Rationale: An INR of 1.8 is below the therapeutic range for a client on warfarin, indicating the need for monitoring closely to ensure that the INR levels reach the desired therapeutic range. Increasing the dose of warfarin (Choice A) without proper monitoring may lead to an increased risk of bleeding. Administering vitamin K (Choice B) is not typically recommended unless the client is experiencing major bleeding or requires rapid reversal of warfarin's effects. Holding the warfarin and notifying the healthcare provider (Choice C) may be necessary in certain situations, but the immediate action in this case should be to monitor the client's INR closely to guide further management.

3. What condition involves a weakened and bulging aorta, the main artery in the body, potentially leading to rupture?

• A. Aortic aneurysm
• B. Arterial stenosis
• C. Pulmonary embolism
• D. Deep vein thrombosis

Correct answer: A

Rationale: An aortic aneurysm is a condition characterized by the weakening and bulging of the aorta, the body's main artery. If left untreated, this bulging may lead to a rupture, causing severe complications. Arterial stenosis refers to the narrowing of an artery, not the weakening and bulging seen in an aortic aneurysm. Pulmonary embolism involves a blockage in the pulmonary artery, which is different from the weakening and bulging in an aortic aneurysm. Deep vein thrombosis is the formation of a blood clot in a deep vein, not related to the condition described in the question.

4. The client on digoxin has a potassium level of 3.0 mEq/L. What is the nurse’s priority action?

• A. Administer a potassium supplement
• B. Hold the digoxin and notify the healthcare provider
• C. Continue the current digoxin dose
• D. Administer Digibind

Correct answer: B

Rationale: The correct answer is to hold the digoxin and notify the healthcare provider. A potassium level of 3.0 mEq/L indicates hypokalemia, which can increase the risk of digoxin toxicity. Digoxin and low potassium levels can lead to serious cardiac arrhythmias. Administering a potassium supplement (choice A) without healthcare provider guidance can worsen the situation. Continuing the current digoxin dose (choice C) can further increase the risk of toxicity. Administering Digibind (choice D) is used in severe cases of digoxin toxicity, not for addressing low potassium levels.

5. During which process does coronary artery blood flow to the myocardium occur during diastole, when coronary vascular resistance is reduced?

• A. Coronary perfusion pressure
• B. Coronary vascular resistance
• C. Diastolic filling
• D. Ventricular ejection

Correct answer: A

Rationale: The correct answer is A: Coronary perfusion pressure. Coronary perfusion pressure refers to the process of coronary artery blood flow to the myocardium during diastole when coronary vascular resistance is reduced. This process ensures that the myocardium receives sufficient oxygen and nutrients for proper functioning. Choice B, Coronary vascular resistance, is the opposite of what is described in the question. During coronary perfusion, resistance is reduced to enhance blood flow. Choices C and D, Diastolic filling and Ventricular ejection, do not directly relate to the process of coronary artery blood flow during diastole.
