Nursing Elites

1. A client with a history of atrial fibrillation is receiving warfarin (Coumadin) therapy. Which laboratory result indicates that the therapy is effective?

• A. International normalized ratio (INR) of 1.0.
• B. Prothrombin time (PT) of 12 seconds.
• C. Partial thromboplastin time (PTT) of 60 seconds.
• D. International normalized ratio (INR) of 2.5.

Correct answer: D

Rationale: An International Normalized Ratio (INR) of 2.5 indicates that warfarin therapy is within the therapeutic range for a client with atrial fibrillation. A lower INR (such as 1.0) would suggest subtherapeutic levels, risking blood clots. Prothrombin time (PT) and partial thromboplastin time (PTT) are not specific to monitoring warfarin therapy.

2. The nurse is assessing a client who complains of weight loss, racing heart rate, and difficulty sleeping. The nurse determines the client has moist skin with fine hair, prominent eyes, lid retraction, and a staring expression. These findings are consistent with which disorder?

• A. Graves' disease.
• B. Cushing's syndrome.
• C. Addison's disease.
• D. Hypothyroidism.

Correct answer: A

Rationale: The correct answer is A, Graves' disease. The symptoms described in the client are classic manifestations of hyperthyroidism, which is commonly caused by Graves' disease, an autoimmune condition affecting the thyroid. Weight loss, racing heart rate, difficulty sleeping, moist skin with fine hair, prominent eyes, lid retraction, and a staring expression are all indicative of hyperthyroidism. Choice B, Cushing's syndrome, is characterized by weight gain, hypertension, and a rounded face due to excess cortisol. Choice C, Addison's disease, presents with symptoms such as weight loss, fatigue, and hyperpigmentation due to adrenal insufficiency. Choice D, hypothyroidism, typically features symptoms opposite to those described in the client, such as weight gain, bradycardia, and dry skin.

3. The healthcare provider is caring for a client with syndrome of inappropriate antidiuretic hormone (SIADH). Which intervention is most important?

• A. Restrict fluids to 1,000 mL per day.
• B. Administer a vasopressin antagonist.
• C. Monitor intake and output.
• D. Encourage a high-sodium diet.

Correct answer: B

Rationale: Administering a vasopressin antagonist is the most critical intervention for a client with SIADH. SIADH is characterized by excessive release of antidiuretic hormone (ADH), leading to water retention and dilutional hyponatremia. A vasopressin antagonist helps manage the symptoms by blocking the effects of ADH, promoting water excretion, and restoring electrolyte balance. Restricting fluids (choice A) may exacerbate hyponatremia, monitoring intake and output (choice C) is important but not the most critical intervention, and encouraging a high-sodium diet (choice D) is contraindicated in SIADH due to the risk of worsening hyponatremia.

4. A client with a history of myocardial infarction is prescribed aspirin therapy. Which instruction should the nurse include in the client's teaching plan?

• A. Take aspirin with food.
• B. Take aspirin at the same time every day.
• C. Avoid taking aspirin with alcohol.
• D. Discontinue aspirin if you experience ringing in your ears.

Correct answer: C

Rationale: The correct instruction for the nurse to include in the client's teaching plan is to avoid taking aspirin with alcohol. Combining aspirin with alcohol can increase the risk of gastrointestinal bleeding and other complications. Taking aspirin with food helps reduce stomach upset, but it is not the most crucial instruction in this scenario. While taking aspirin at the same time every day can help with consistency, it is not as critical as avoiding alcohol. Discontinuing aspirin if experiencing ringing in the ears is important to address potential side effects, but it is not directly related to preventing complications when combining with alcohol.

5. A client with a history of alcohol abuse is admitted with acute pancreatitis. Which assessment finding requires immediate intervention?

• A. Amylase of 120 U/L.
• B. Lipase of 150 U/L.
• C. Calcium of 8.5 mg/dL.
• D. Temperature of 101°F (38.3°C).

Correct answer: D

Rationale: In a client with acute pancreatitis and a history of alcohol abuse, a temperature of 101°F (38.3°C) can indicate infection, which is a serious complication requiring immediate intervention. Elevated amylase and lipase levels are common in acute pancreatitis but do not directly indicate the need for urgent intervention. A calcium level of 8.5 mg/dL is within the normal range and does not require immediate action in this context.
