Nursing Elites

1. Prior to administering warfarin to a client with a history of atrial fibrillation, what lab result should the nurse review?

• A. White blood cell count.
• B. Prothrombin time (PT) and International Normalized Ratio (INR).
• C. Hemoglobin and hematocrit.
• D. Blood urea nitrogen (BUN) and creatinine.

Correct answer: B

Rationale: The correct answer is B: Prothrombin time (PT) and International Normalized Ratio (INR). These lab values are crucial for monitoring the effectiveness of warfarin, an anticoagulant medication. PT measures the time it takes for blood to clot, while INR standardizes these results. Ensuring the client's PT/INR levels are within the therapeutic range is essential to prevent clotting or excessive bleeding. Choices A, C, and D are incorrect as they are not directly related to monitoring warfarin therapy in a client with atrial fibrillation.

2. A client with chronic heart failure is admitted with worsening dyspnea. What is the nurse's priority action?

• A. Administer oxygen at 2 liters per nasal cannula.
• B. Administer a diuretic as prescribed.
• C. Assess the client's lung sounds.
• D. Reposition the client to relieve dyspnea.

Correct answer: A

Rationale: In a client with chronic heart failure experiencing worsening dyspnea, the priority action for the nurse is to administer oxygen at 2 liters per nasal cannula. This helps improve oxygenation and alleviate respiratory distress. Administering a diuretic (Choice B) may be necessary but addressing oxygenation comes first. While assessing lung sounds (Choice C) is important, it is not the immediate priority when the client is in respiratory distress. Repositioning the client (Choice D) may help with comfort but does not address the underlying issue of inadequate oxygenation.

3. A client with diabetes mellitus reports feeling shaky, dizzy, and sweaty. The nurse checks the client's blood glucose level and it is 55 mg/dL. What is the nurse's next action?

• A. Give the client a glucagon injection
• B. Encourage the client to eat a high-protein snack
• C. Administer 15 grams of a fast-acting carbohydrate
• D. Recheck the blood glucose level in 15 minutes

Correct answer: C

Rationale: A blood glucose level of 55 mg/dL indicates hypoglycemia, which should be treated with a fast-acting carbohydrate to quickly raise the blood sugar. Administering 15 grams of a fast-acting carbohydrate, such as glucose tablets or juice, is the appropriate initial intervention for hypoglycemia. Giving a glucagon injection is reserved for severe cases or when the client is unconscious. Encouraging the client to eat a high-protein snack is not appropriate for treating acute hypoglycemia, as it is a slower-acting form of glucose. Rechecking the blood glucose level is important but should occur after providing immediate treatment to raise the blood sugar level.

4. Prolonged exposure to high concentrations of supplemental oxygen over several days can cause which pathophysiological effect?

• A. Reduced cardiac output
• B. Disrupted surfactant production
• C. Hyperactivity of alveoli
• D. Increased oxygen carrying capacity

Correct answer: B

Rationale: Corrected Rationale: Prolonged exposure to high oxygen concentrations can disrupt the production of surfactant in the lungs, leading to atelectasis and other lung complications. Surfactant is essential for maintaining lung compliance and preventing alveolar collapse. Reduced cardiac output (Choice A) is not directly associated with prolonged oxygen exposure. Hyperactivity of alveoli (Choice C) is not a recognized consequence of high oxygen levels. Increased oxygen carrying capacity (Choice D) is not a pathophysiological effect of prolonged high oxygen exposure.

5. The nurse is providing discharge teaching to a client with gastroesophageal reflux disease (GERD). Which instruction should the nurse include in the teaching?

• A. Increase fluid intake with meals
• B. Avoid lying down for at least 30 minutes after eating
• C. Eat small, frequent meals throughout the day
• D. Consume spicy foods in moderation

Correct answer: C

Rationale: The correct instruction for the nurse to include in the teaching for a client with GERD is to eat small, frequent meals throughout the day. This recommendation helps reduce symptoms by preventing the stomach from becoming overly full, which can increase pressure on the lower esophageal sphincter and lead to acid reflux. Choices A, B, and D are incorrect because increasing fluid intake with meals can exacerbate GERD symptoms, lying down after eating can worsen reflux, and consuming spicy foods can trigger acid reflux in individuals with GERD.
