1. What test measures the oxygen level in the blood, often used to monitor patients with respiratory or cardiovascular conditions?

• A. Pulse oximetry
• B. Arterial blood gas (ABG)
• C. Echocardiogram
• D. Chest X-ray

Correct answer: A

Rationale: The correct answer is A, Pulse oximetry. Pulse oximetry is a non-invasive test that measures the oxygen saturation level in the blood, commonly used to monitor respiratory and cardiovascular health. Arterial blood gas (ABG) measures the levels of oxygen and carbon dioxide in the blood, providing more detailed information than pulse oximetry. Echocardiogram is an ultrasound test used to visualize the heart's structure and function, while a chest X-ray is used to visualize the structures in the chest, such as the heart, lungs, and bones.

2. What is a condition where the lungs become stiff and scarred, making it difficult to breathe and get enough oxygen into the bloodstream?

• A. Pulmonary fibrosis
• B. Pulmonary edema
• C. Pulmonary embolism
• D. Pulmonary hypertension

Correct answer: A

Rationale: Pulmonary fibrosis is a condition characterized by the stiffening and scarring of the lungs, leading to difficulty breathing and impairing the transfer of oxygen into the bloodstream. Pulmonary edema refers to fluid accumulation in the lungs, causing breathing difficulties due to fluid filling the air sacs. Pulmonary embolism is a blockage in one of the pulmonary arteries in the lungs, often caused by a blood clot. Pulmonary hypertension is high blood pressure in the arteries of the lungs, which can lead to strain on the heart and affect oxygen levels in the blood.

3. 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.

4. The client is prescribed warfarin. What should the client be taught about this medication?

• A. Avoid foods high in vitamin K.
• B. Take the medication with food to prevent stomach upset.
• C. Take the medication at the same time every day.
• D. Increase the dose if a dose is missed.

Correct answer: A

Rationale: The correct answer is A: Avoid foods high in vitamin K. Warfarin is an anticoagulant medication, and vitamin K can counteract its effects. Therefore, it is important for clients taking warfarin to avoid foods high in vitamin K to maintain the medication's effectiveness. Choice B is incorrect because warfarin should be taken consistently as prescribed, regardless of food intake. Choice C is incorrect because while consistency in timing is important, it is not specific to the effectiveness of warfarin. Choice D is incorrect because clients should never increase the dose of warfarin on their own, especially to make up for a missed dose, as it can lead to serious bleeding risks.

5. 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. A blood pressure test is specifically designed to measure the pressure inside the arteries as the heart pumps blood. This test is crucial in providing information about cardiovascular health by determining the force of blood against the artery walls. Choice B, Pulse oximetry, measures oxygen saturation in the blood, not blood pressure. Choice C, Echocardiogram, is an ultrasound test that evaluates the structure and function of the heart, not specifically blood pressure. Choice D, Spirometry, is a test used to assess lung function, not blood pressure.
