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. When a client on nitroglycerin reports chest pain, it could indicate a worsening condition or potential myocardial infarction. The nurse's priority is to notify the healthcare provider promptly for further assessment and intervention. Administering nitroglycerin (choice A) may not address the underlying cause of the chest pain. Administering morphine (choice B) may mask symptoms and delay appropriate treatment. Administering aspirin (choice C) is important in chest pain management but does not take priority over notifying the healthcare provider for further evaluation and guidance.

The nurse is administering a calcium channel blocker. What is the primary effect of this medication on the cardiovascular system?
- A. Decreases heart rate
- B. Increases heart rate
- C. Increases blood pressure
- D. Decreases blood pressure
Correct Answer: D
Rationale: The correct answer is D: Decreases blood pressure. Calcium channel blockers inhibit the influx of calcium into cardiac and smooth muscle cells, leading to vasodilation and decreased peripheral resistance, ultimately reducing blood pressure. This effect is beneficial in conditions such as hypertension and angina. The other choices are incorrect because calcium channel blockers typically do not directly affect heart rate or increase blood pressure.
What test measures the pressure inside the arteries as the heart pumps blood?
- A. Blood pressure test
- B. Pulse oximetry
- C. Echocardiogram
- D. Spirometry
Correct Answer: A
Rationale: The correct answer is A: Blood pressure test. This test measures the pressure inside the arteries during the heart's pumping cycle. It assesses systolic and diastolic pressure, indicating the force exerted by blood on artery walls. Pulse oximetry (B) measures oxygen saturation, not arterial pressure. Echocardiogram (C) is an ultrasound that assesses heart structure and function, not arterial pressure. Spirometry (D) measures lung function, not arterial pressure. Therefore, the blood pressure test is the most relevant choice for assessing arterial pressure.
What type of medication is used to relax the muscles around the airways and improve breathing in conditions like asthma and COPD?
- A. Bronchodilator
- B. Corticosteroid
- C. Mucolytic
- D. Antihistamine
Correct Answer: A
Rationale: The correct answer is A: Bronchodilator. Bronchodilators are used to relax the muscles around the airways, allowing them to open up and improve breathing in conditions like asthma and COPD. They work by widening the airways, making it easier to breathe. Corticosteroids (B) reduce inflammation, mucolytics (C) help loosen mucus, and antihistamines (D) are used for allergies and not specifically for relaxing muscles in the airways. Therefore, A is the correct choice for this question.
The client is on warfarin and has an INR of 1.5. What is the nurse's priority action?
- A. Increase the dose of warfarin.
- B. Hold the next dose of warfarin.
- C. Continue the current dose of warfarin.
- D. Monitor the client's INR closely.
Correct Answer: B
Rationale: The correct answer is B: Hold the next dose of warfarin. With an INR of 1.5, the client's blood is not adequately anticoagulated, increasing the risk of blood clots. Holding the next dose will prevent further thinning of blood and allow the INR to increase to the target range. Increasing the dose (A) could lead to over-anticoagulation, risking bleeding. Continuing the current dose (C) maintains inadequate anticoagulation. Monitoring (D) is important, but the immediate action should be to hold the next dose.
Which condition involves the tearing of the aorta, leading to severe pain and internal bleeding?
- A. Aortic dissection
- B. Aneurysm
- C. Stroke
- D. Myocardial infarction
Correct Answer: A
Rationale: The correct answer is A: Aortic dissection. This condition involves a tear in the inner layer of the aorta, leading to severe pain and internal bleeding. The tearing causes blood to flow between the layers of the aortic wall, which can be life-threatening. Aneurysm (B) is the abnormal bulging of a weakened blood vessel, not necessarily involving tearing. Stroke (C) is a brain-related condition, not related to the aorta. Myocardial infarction (D) is a heart attack due to blockage of blood flow to the heart, not directly involving the aorta.
