Nursing Elites

1. What is a condition where the blood pressure in the arteries is consistently too high, increasing the risk of heart disease and stroke?

• A. Hypertension
• B. Hypotension
• C. Diabetes
• D. Hyperlipidemia

Correct answer: A

Rationale: Hypertension, also known as high blood pressure, is a condition where the force of the blood against the artery walls is consistently too high. This increased pressure can lead to serious health issues such as heart disease and stroke. Hypotension (choice B) refers to low blood pressure, which is not the correct term in this context. Diabetes (choice C) and hyperlipidemia (choice D) are also serious conditions but are not specifically characterized by consistently high blood pressure.

2. When monitoring a client on dobutamine, what is the most important parameter to assess?

• A. Blood pressure
• B. Heart rate
• C. Oxygen saturation
• D. Respiratory rate

Correct answer: A

Rationale: The correct answer is A: Blood pressure. When a client is on dobutamine, it is crucial to closely monitor their blood pressure as dobutamine can cause significant changes in blood pressure. While heart rate is also important to monitor during this time, blood pressure is the most critical parameter to assess. Oxygen saturation and respiratory rate are also important parameters to monitor in a patient receiving dobutamine, but they are not as crucial as blood pressure in this scenario.

3. Which surgical procedure involves grafting a blood vessel to bypass a blocked artery in the heart?

• A. Coronary artery bypass graft (CABG)
• B. Valve replacement
• C. Stent placement
• D. Angioplasty

Correct answer: A

Rationale: The correct answer is A, Coronary artery bypass graft (CABG). This surgical procedure involves grafting a blood vessel to bypass a blocked coronary artery, improving blood flow to the heart muscle. Choice B, Valve replacement, is a procedure to replace a damaged heart valve and is not directly related to bypassing blocked arteries. Choice C, Stent placement, involves inserting a mesh tube to keep blocked arteries open and is different from grafting a blood vessel. Choice D, Angioplasty, is a procedure to widen narrowed or blocked arteries, typically using a balloon catheter, and does not involve grafting a blood vessel.

4. The client is on amiodarone and reports blurred vision. What is the nurse’s best response?

• A. Reassure the client that this is a common side effect.
• B. Instruct the client to report this symptom to the healthcare provider immediately.
• C. Advise the client to stop taking the medication.
• D. Discontinue the amiodarone immediately.

Correct answer: B

Rationale: Blurred vision is a potential side effect of amiodarone. Instructing the client to report this symptom to the healthcare provider immediately is the most appropriate response. Choice A is incorrect because although blurred vision can be a common side effect of amiodarone, it should not be dismissed without further evaluation. Choice C is incorrect as advising the client to stop taking the medication without consulting the healthcare provider can be dangerous and is not the first course of action. Choice D is too drastic as discontinuing the medication should be done under the guidance of a healthcare provider after proper evaluation.

5. Which neurotransmitter released by the parasympathetic nervous system can decrease heart rate?

• A. Acetylcholine
• B. Norepinephrine
• C. Dopamine
• D. Serotonin

Correct answer: A

Rationale: Acetylcholine is the correct answer. It is a neurotransmitter released by the parasympathetic nervous system that can decrease heart rate. Norepinephrine, dopamine, and serotonin are neurotransmitters that usually have different effects on the body and are not specifically associated with decreasing heart rate. Norepinephrine, for example, is often related to the fight-or-flight response and can increase heart rate.
