Nursing Elites

1. A nurse is caring for a client who came to the emergency department reporting chest pain. The provider suspects a myocardial infarction. While waiting for the laboratory to report the client's troponin levels, the client asks what this blood test will show. The nurse should explain that troponin is

• A. an enzyme that indicates damage to brain, heart, and skeletal muscle tissues.
• B. a protein whose levels reflect the risk for coronary artery disease.
• C. a heart muscle protein that appears in the bloodstream when there is damage to the heart.
• D. a protein that helps transport oxygen throughout the body.

Correct answer: C

Rationale: The correct answer is that troponin is a heart muscle protein that appears in the bloodstream when there is damage to the heart. Troponin is a specific marker for heart muscle damage, particularly seen in conditions like myocardial infarction. Choice A is incorrect as troponin is not an enzyme that indicates damage to brain and skeletal muscle tissues. Choice B is incorrect as troponin is not a protein whose levels reflect the risk for coronary artery disease; it indicates heart muscle damage. Choice D is incorrect as troponin is not a protein that helps transport oxygen throughout the body; its presence in the bloodstream is specific to heart muscle damage.

2. A client with angina pectoris is being taught about starting therapy with nitroglycerin (Nitrostat) tablets. The nurse should instruct the client to take the medication

• A. after each meal and at bedtime.
• B. every 15 minutes during an acute attack.
• C. at the first indication of chest pain.
• D. with 8 oz of water.

Correct answer: C

Rationale: Nitroglycerin (Nitrostat) tablets are used to relieve chest pain associated with angina. The client should take the medication at the first indication of chest pain to help dilate blood vessels and improve blood flow to the heart muscle. Choice A is incorrect because nitroglycerin should not be scheduled after each meal or at bedtime. Choice B is incorrect as taking the medication every 15 minutes during an acute attack is excessive and not recommended. Choice D is incorrect because while it is important to take nitroglycerin with water, the timing of water intake is not as critical as taking the medication at the first sign of chest pain.

3. A client is telling the nurse in the clinic that he gets a headache after taking sublingual nitroglycerin (Nitrostat) for his angina pain. Which of the following should the nurse instruct the client to do?

• A. Reduce the nitroglycerin dose
• B. Ask the provider to prescribe a strong analgesic
• C. Lie down in a cool environment and rest
• D. Ask the provider to prescribe a different medication

Correct answer: C

Rationale: The correct answer is to instruct the client to lie down in a cool environment and rest after taking sublingual nitroglycerin for angina pain. Headaches are a common side effect of nitroglycerin due to its vasodilatory effects, and resting in a cool environment can help alleviate the headache. Reducing the nitroglycerin dose is not recommended without consulting the healthcare provider as it may compromise the effectiveness of the medication in managing angina. Asking for a strong analgesic is not appropriate since the headache is likely related to the nitroglycerin and not a separate issue requiring a pain reliever. Requesting a different medication should also involve consulting the healthcare provider to ensure an appropriate alternative is prescribed for angina management.

4. A provider is discharging a client with a prescription for home oxygen therapy. Client and family teaching by the nurse should include all of the following instructions except?

• A. Cleanse the mask or collar with soapy water every other day.
• B. Ensure that the straps on the mask are secure but not too tight.
• C. Apply petroleum jelly around and inside the nares.
• D. Post 'no smoking' warning signs at home in a prominent location.

Correct answer: C

Rationale: When providing instructions for home oxygen therapy, it is important to ensure safety and proper care. Choices A, B, and D are all essential instructions for the client and family. Choice C, 'Apply petroleum jelly around and inside the nares,' is incorrect. Petroleum jelly should not be used near oxygen sources as it is flammable and can increase the risk of fire hazard. Therefore, this instruction should not be included in the teaching.

5. A client comes to the emergency department reporting chest pain that is sharp, knife-like, and localized to an area he points to with one finger. The nurse should document this chest pain as which of the following?

• A. Angina pectoris
• B. Cardiogenic pain
• C. Myocardial infarction
• D. Pleuritic pain

Correct answer: D

Rationale: The correct answer is 'Pleuritic pain.' Pleuritic pain is characterized by sharp, knife-like pain that worsens with deep breathing or coughing and is localized to a specific area. This type of pain is often associated with inflammation of the pleura. Choices A, B, and C are incorrect. Angina pectoris is a type of chest pain caused by reduced blood flow to the heart muscle. Cardiogenic pain refers to pain originating from the heart itself. Myocardial infarction is the medical term for a heart attack.
