Nursing Elites

1. When assessing a client with a chest tube connected to suction, which observation indicates that the chest tube is functioning properly?

• A. Continuous bubbling in the water seal chamber.
• B. Intermittent bubbling in the suction control chamber.
• C. No fluctuation in the water seal chamber.
• D. Steady bubbling in the suction control chamber.

Correct answer: D

Rationale: Steady bubbling in the suction control chamber is the correct observation that indicates the chest tube is functioning properly. This steady bubbling signifies that the suction is actively maintaining the desired pressure level within the system, ensuring proper drainage and lung re-expansion. Continuous bubbling in the water seal chamber, intermittent bubbling in the suction control chamber, or no fluctuation in the water seal chamber are not indicative of optimal chest tube function and may require further assessment or intervention.

2. A client has developed hepatic encephalopathy secondary to cirrhosis and is receiving care on the medical unit. The client's current medication regimen includes lactulose four times daily. What desired outcome should the nurse relate to this pharmacologic intervention?

• A. Two to three soft bowel movements daily
• B. Significant increase in appetite and food intake
• C. Absence of nausea and vomiting
• D. Absence of blood or mucus in stool

Correct answer: A

Rationale: Lactulose is used in hepatic encephalopathy to reduce blood ammonia levels by promoting bowel movements. The desired outcome of lactulose therapy is typically two to three soft bowel movements daily, which helps in eliminating excess ammonia from the body, thus improving the client's condition.

3. What is an important teaching point for a patient prescribed dabigatran for atrial fibrillation?

• A. Take the medication with food to enhance absorption.
• B. Do not crush or chew the capsules.
• C. Increase intake of green leafy vegetables.
• D. Avoid all dairy products.

Correct answer: B

Rationale: The correct teaching point for a patient prescribed dabigatran is not to crush or chew the capsules. Doing so can alter the absorption of the medication, increasing the risk of bleeding. It is important for patients to swallow the capsules whole to ensure proper delivery of the medication.

4. A patient with deep vein thrombosis (DVT) is prescribed warfarin. Which dietary instruction should the nurse provide?

• A. Avoid foods high in vitamin K.
• B. Increase intake of dairy products.
• C. Limit intake of citrus fruits.
• D. Avoid high-sodium foods.

Correct answer: A

Rationale: Patients on warfarin should avoid foods high in vitamin K because vitamin K can interfere with the anticoagulant effect of the medication. Warfarin works by inhibiting vitamin K-dependent clotting factors, so consuming large amounts of vitamin K-rich foods may decrease the effectiveness of the medication. Choices B, C, and D are incorrect. Increasing intake of dairy products, limiting citrus fruits, or avoiding high-sodium foods are not directly related to the mechanism of action of warfarin or its dietary considerations.

5. A 35-year-old man presents with fatigue, weight loss, and hyperpigmentation of the skin. Laboratory tests reveal hyponatremia, hyperkalemia, and low cortisol levels. What is the most likely diagnosis?

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

Correct answer: B

Rationale: The clinical presentation of a 35-year-old man with fatigue, weight loss, hyperpigmentation of the skin, hyponatremia, hyperkalemia, and low cortisol levels is classic for Addison's disease. These findings are consistent with primary adrenal insufficiency, where the adrenal glands fail to produce adequate cortisol. In Addison's disease, the adrenal cortex is damaged, leading to decreased cortisol production and elevated levels of ACTH. This results in symptoms such as fatigue, weight loss, and hyperpigmentation due to increased ACTH production stimulating melanocytes. Hyponatremia and hyperkalemia are common electrolyte abnormalities seen in Addison's disease due to aldosterone deficiency. Therefore, the correct diagnosis in this case is Addison's disease.
