Nursing Elites

1. A client with a history of atrial fibrillation is prescribed warfarin. What is the nurse's priority teaching?

• A. Avoid eating foods high in potassium.
• B. Avoid foods high in vitamin K.
• C. Take the medication on an empty stomach.
• D. Take the medication at bedtime for best results.

Correct answer: B

Rationale: The correct answer is B: 'Avoid foods high in vitamin K.' Warfarin is an anticoagulant medication that works by interfering with vitamin K-dependent clotting factors. Therefore, consuming foods high in vitamin K can affect the medication's effectiveness. Choices A, C, and D are incorrect because: A) Warfarin is not affected by foods high in potassium; C) Warfarin should be taken with food to minimize gastrointestinal side effects; D) There is no specific requirement for taking warfarin at bedtime for best results.

2. A client with heart failure is prescribed digoxin and reports nausea. What is the nurse's first action?

• A. Administer an anti-nausea medication as prescribed.
• B. Assess the client's digoxin level immediately.
• C. Assess the client’s apical pulse and hold the next dose if it's below 60 bpm.
• D. Instruct the client to reduce their fluid intake.

Correct answer: B

Rationale: When a client on digoxin reports nausea, it can be a sign of digoxin toxicity. The priority action for the nurse is to assess the client's digoxin level immediately. This assessment will help determine if the nausea is related to digoxin toxicity, requiring a dosage adjustment. Administering an anti-nausea medication (Choice A) does not address the underlying issue of potential digoxin toxicity. Assessing the client's apical pulse (Choice C) is important in general digoxin monitoring but not the first action when nausea is reported. Instructing the client to reduce fluid intake (Choice D) is not the initial response to nausea in a client taking digoxin.

3. A client is receiving 30 mg of enoxaparin subcutaneously twice a day. In assessing adverse effects of the medication, which serum laboratory value is most important for the nurse to monitor?

• A. Hemoglobin level
• B. Platelet count
• C. Activated partial thromboplastin time (aPTT)
• D. Prothrombin time (PT)

Correct answer: B

Rationale: The correct answer is B: Platelet count. Enoxaparin can cause heparin-induced thrombocytopenia (HIT), making it crucial to monitor the platelet count for signs of thrombocytopenia. Monitoring the platelet count helps in early detection of this serious adverse effect. Choices A, C, and D are less relevant in this context. Hemoglobin level checks are more indicative of bleeding issues rather than thrombocytopenia caused by enoxaparin. Activated partial thromboplastin time (aPTT) and prothrombin time (PT) are less impacted by enoxaparin and are not typically used to monitor for HIT.

4. While changing a client's chest tube dressing, the nurse notes a cracking sensation when gentle pressure is applied to the skin at the insertion site. What should the nurse do next?

• A. Apply a pressure dressing at the chest tube site.
• B. Administer an oral antihistamine per PRN order.
• C. Assess the client for allergies to topical cleaning agents.
• D. Measure the area of crackling and swelling.

Correct answer: D

Rationale: Measuring the area of crackling and swelling is essential in monitoring the progression of subcutaneous emphysema, which can result from air leaking into the tissues around the chest tube insertion site. This technique helps evaluate the extent of the issue and guides further interventions. Applying a pressure dressing (choice A) might exacerbate the condition by trapping more air. Administering an oral antihistamine (choice B) is not indicated for subcutaneous emphysema. Assessing for allergies to topical cleaning agents (choice C) is not the priority in this situation compared to evaluating and managing the subcutaneous emphysema.

5. An older client with a long history of coronary artery disease, HTN, and HF arrives in the ED in respiratory distress. The healthcare provider prescribes furosemide IV. Which therapeutic response to furosemide should the nurse expect in the client with acute HF?

• A. Decreased heart rate
• B. Improved blood pressure
• C. Increased urine output
• D. Reduced preload

Correct answer: D

Rationale: The correct answer is D: Reduced preload. Furosemide is a diuretic that reduces fluid overload in heart failure, which lowers the preload (the volume of blood in the ventricles before contraction). By reducing this volume, furosemide improves symptoms of heart failure. While furosemide may lead to increased urine output and lower blood pressure, these effects are secondary to the reduction in preload. Decreased heart rate is not a direct effect of furosemide in heart failure.
