Nursing Elites

1. A client who has a new prescription for warfarin is being educated by a healthcare professional about monitoring for adverse effects. Which of the following statements by the client indicates an understanding of the teaching?

• A. 'I should use a soft toothbrush to brush my teeth.'
• B. 'I will double my dose if I miss one.'
• C. 'I should increase my intake of leafy green vegetables.'
• D. 'I will contact my doctor if I notice any unusual bleeding or bruising.'

Correct answer: D

Rationale: The correct answer is D: 'I will contact my doctor if I notice any unusual bleeding or bruising.' This statement indicates a good understanding of the teaching regarding warfarin. Warfarin is an anticoagulant medication that increases the risk of bleeding. Contacting the doctor if unusual bleeding or bruising is noticed is essential as it can help prevent serious complications. Choices A, B, and C are incorrect. Using a soft toothbrush is generally recommended for oral hygiene but is not directly related to monitoring for adverse effects of warfarin. Doubling the dose of warfarin if a dose is missed is dangerous and can increase the risk of bleeding. Increasing the intake of leafy green vegetables can interfere with warfarin's effectiveness as they contain vitamin K, which antagonizes warfarin's anticoagulant effects.

2. Why should the client diagnosed with rheumatic heart disease be advised to notify the dentist before dental procedures?

• A. The client requires prophylactic antibiotics before treatment.
• B. The client may experience dysrhythmias with high-speed drills.
• C. The client may have an adverse reaction to lidocaine with epinephrine.
• D. The client may develop heart failure during stressful events.

Correct answer: A

Rationale: Clients with rheumatic heart disease are at risk for infective endocarditis, a serious infection of the heart lining or valves. They need prophylactic antibiotics before invasive procedures, including dental work, to prevent this life-threatening complication. While dysrhythmias with high-speed drills, adverse reactions to local anesthesia, and the risk of heart failure during stressful events are all concerns for clients with heart conditions, the primary reason for notifying the dentist before dental procedures in rheumatic heart disease is the need for prophylactic antibiotics to prevent infective endocarditis.

3. A client with chronic stable angina is prescribed nitroglycerin (Nitrostat) for chest pain. The nurse should include which instruction when teaching the client about this medication?

• A. Take nitroglycerin at the first sign of chest pain.
• B. Swallow the tablet whole with water.
• C. Take nitroglycerin with meals to prevent stomach upset.
• D. Store nitroglycerin in a cool, dry place.

Correct answer: A

Rationale: The correct instruction when teaching a client about nitroglycerin (Nitrostat) is to take it at the first sign of chest pain. Nitroglycerin works rapidly to dilate blood vessels, improving blood flow to the heart muscle. Taking it promptly can help alleviate symptoms quickly and prevent the condition from worsening. Choice B is incorrect because nitroglycerin is usually taken sublingually (under the tongue) and not swallowed. Choice C is incorrect because nitroglycerin is not typically taken with meals. Choice D is incorrect because nitroglycerin should be stored in its original container away from heat and light.

4. A client with a history of angina pectoris complains of substernal chest pain. The nurse checks the client's blood pressure and administers nitroglycerin 0.4 mg sublingually. Five minutes later, the client is still experiencing chest pain. If the blood pressure is still stable, what should the nurse do next?

• A. Administer another nitroglycerin tablet.
• B. Apply 1 to 3 L/minute of oxygen via nasal cannula.
• C. Call for a 12-lead electrocardiogram (ECG) to be performed.
• D. Wait an additional 5 minutes, then give a second nitroglycerin tablet.

Correct answer: A

Rationale: When a client with angina pectoris continues to experience chest pain despite initial nitroglycerin administration and stable blood pressure, the appropriate next step is to administer another nitroglycerin tablet. This helps to further dilate coronary arteries, improving blood flow to the heart muscle and relieving chest pain. Applying oxygen via nasal cannula (Choice B) may be necessary if the client displays signs of respiratory distress or hypoxemia, but in this case, the priority is addressing the unresolved chest pain. Calling for a 12-lead electrocardiogram (ECG) (Choice C) is important to assess for any changes in the client's cardiac status, but administering another nitroglycerin tablet takes precedence in managing the ongoing chest pain. Waiting an additional 5 minutes before giving a second nitroglycerin tablet (Choice D) may delay symptom relief and potentially worsen the client's condition if the chest pain persists.

5. The client has atrial fibrillation and is receiving warfarin (Coumadin) therapy. Which laboratory test should be monitored to evaluate the effectiveness of the warfarin therapy?

• A. Prothrombin time (PT) and international normalized ratio (INR)
• B. Activated partial thromboplastin time (aPTT)
• C. Complete blood count (CBC)
• D. Fibrinogen levels

Correct answer: A

Rationale: Monitoring the Prothrombin time (PT) and international normalized ratio (INR) is crucial for assessing the effectiveness of warfarin therapy. These tests help determine the clotting ability of the blood and ensure that the client is within the desired therapeutic range to prevent clotting events or bleeding complications. Activated partial thromboplastin time (aPTT) (Choice B) is more commonly used to monitor heparin therapy, not warfarin. Complete blood count (CBC) (Choice C) and fibrinogen levels (Choice D) do not directly assess the effectiveness of warfarin therapy in the same way that PT and INR do.
