Nursing Elites

1. A client with atrial fibrillation is receiving warfarin (Coumadin). The nurse should monitor which laboratory test to determine the effectiveness of the therapy?

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

Correct answer: A

Rationale: To monitor the effectiveness of warfarin therapy in a client with atrial fibrillation, the nurse should assess the Prothrombin time (PT) and international normalized ratio (INR) levels. These tests help determine the clotting ability of the blood and ensure that the client's anticoagulation levels are within the therapeutic range, reducing the risk of bleeding or clotting complications. Activated partial thromboplastin time (aPTT) (Choice B) is more commonly used to monitor heparin therapy. Complete blood count (CBC) (Choice C) provides information about the cellular components of blood but does not directly assess the effectiveness of warfarin therapy. Fibrinogen level (Choice D) is not typically used to monitor warfarin therapy; it reflects the level of fibrinogen in the blood, which is involved in the clotting process.

2. The nurse is caring for a client diagnosed with heart failure who is taking digoxin (Lanoxin). Which sign of digoxin toxicity should the nurse monitor for?

• A. Hypertension
• B. Bradycardia
• C. Hyperglycemia
• D. Insomnia

Correct answer: B

Rationale: The correct answer is B: Bradycardia. Bradycardia is a common sign of digoxin toxicity, as digoxin can cause decreased heart rate. Therefore, monitoring the client for signs of bradycardia is crucial. Choices A, C, and D are incorrect. Hypertension is not typically associated with digoxin toxicity; instead, hypotension may occur. Hyperglycemia is not a common sign of digoxin toxicity. Insomnia is also not a typical sign of digoxin toxicity; instead, some patients may experience visual disturbances, confusion, or other neurological symptoms.

3. The client with a history of left-sided heart failure is exhibiting increasing shortness of breath and frothy sputum. What is the priority nursing action?

• A. Administer oxygen
• B. Encourage coughing and deep breathing
• C. Place the client in a supine position
• D. Notify the healthcare provider immediately

Correct answer: A

Rationale: Shortness of breath and frothy sputum are indicative of pulmonary edema, a serious condition that requires immediate intervention to improve oxygenation. Administering oxygen is the priority action to support the client's respiratory function and prevent further deterioration. Oxygen therapy helps increase the oxygen levels in the blood, alleviate respiratory distress, and support vital organ function. Prompt intervention with oxygen can help stabilize the client while further assessments and treatments are initiated. Encouraging coughing and deep breathing may worsen the client's condition by increasing respiratory effort. Placing the client in a supine position can further compromise breathing in a client with pulmonary edema. Notifying the healthcare provider is important but not the priority when the client's respiratory status is deteriorating.

4. A client is prescribed clopidogrel. What laboratory result should be monitored by the nurse?

• A. White blood cell count
• B. Creatinine
• C. Blood glucose
• D. Platelet count

Correct answer: D

Rationale: When a client is prescribed clopidogrel, monitoring the platelet count is essential. Clopidogrel is an antiplatelet medication that works by preventing blood clots. Monitoring the platelet count is crucial in assessing the risk of thrombocytopenia, a potential side effect of clopidogrel. Monitoring white blood cell count, creatinine, or blood glucose is not directly related to the action or side effects of clopidogrel, making choices A, B, and C incorrect.

5. A client has a new prescription for prednisone. Which of the following statements should the nurse include in the teaching?

• A. You may experience weight gain.
• B. Increase your intake of vitamin K.
• C. Expect increased urinary output.
• D. You may have dark, tarry stools.

Correct answer: A

Rationale: The correct answer is A: 'You may experience weight gain.' Prednisone commonly causes weight gain as a side effect, so it is important for the client to be aware of this potential outcome. Monitoring weight changes can be essential in managing the medication's effects and overall health. Choices B, C, and D are incorrect. Increasing vitamin K intake is not specifically related to prednisone use. Expecting increased urinary output is not a common side effect of prednisone. Dark, tarry stools are more commonly associated with gastrointestinal bleeding rather than prednisone use.
