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. This term refers to a change in the inotropic state of the muscle without a change in myocardial fiber length.

• A. Contractility
• B. Excitability
• C. Refractoriness
• D. Automaticity

Correct answer: A

Rationale: The correct answer is A: Contractility. Contractility specifically refers to the change in the force of contraction of the heart muscle without changing its length. In this scenario, the focus is on the change in the inotropic state of the muscle, which directly relates to contractility. Choice B, Excitability, refers to the ability of a cell to respond to a stimulus, not specifically related to changes in contractile force. Choice C, Refractoriness, pertains to the period during which a cell is unresponsive to a new stimulus. Choice D, Automaticity, refers to the ability of cardiac cells to spontaneously generate electrical impulses.

3. The nurse is teaching a client about side effects of ACE inhibitors. What is the most important side effect to monitor?

• A. Cough
• B. Hyperkalemia
• C. Hypotension
• D. Dizziness

Correct answer: A

Rationale: The correct answer is A: Cough. ACE inhibitors commonly cause a persistent dry cough in patients. This side effect is important to monitor because it can indicate the development of angioedema, a serious adverse reaction that requires immediate medical attention. Hyperkalemia (choice B) is a potential side effect of ACE inhibitors but is not typically the most important one to monitor. Hypotension (choice C) and dizziness (choice D) are also possible side effects of ACE inhibitors, but they are not as critical to monitor as the development of a persistent cough.

4. What is the condition where the lungs become filled with fluid, often due to heart failure, making it difficult to breathe?

• A. Pulmonary edema
• B. Pleural effusion
• C. Pulmonary hypertension
• D. Pneumothorax

Correct answer: A

Rationale: Pulmonary edema is the correct answer. It occurs when fluid fills the lungs, usually due to heart failure, leading to breathing difficulties. Pleural effusion is the accumulation of fluid around the lungs, not inside. Pulmonary hypertension is high blood pressure in the arteries of the lungs, and pneumothorax is the presence of air between the lung and chest wall.

5. The client is on a calcium channel blocker. What is the expected effect on the heart?

• A. Increased heart rate
• B. Decreased heart rate
• C. Increased blood pressure
• D. Decreased blood pressure

Correct answer: D

Rationale: When a client is on a calcium channel blocker, the expected effect on the heart is a decreased heart rate and decreased blood pressure. Calcium channel blockers work by dilating blood vessels and reducing the heart's workload, resulting in decreased blood pressure. Choice A, increased heart rate, is incorrect as calcium channel blockers actually have a negative chronotropic effect, reducing the heart rate. Choice C, increased blood pressure, is also incorrect because these medications are used to lower blood pressure.
