Nursing Elites

1. 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.

2. A client is on a mechanical ventilator. Which client response indicates that the neuromuscular blocker tubocurarine chloride (Tubarine) is effective?

• A. The client's extremities are paralyzed.
• B. The peripheral nerve stimulator causes twitching.
• C. The client clenches fist upon command.
• D. The client's Glasgow Coma Scale score is 14.

Correct answer: A

Rationale: The correct answer is A. Tubocurarine chloride is a neuromuscular blocker that works by causing paralysis of skeletal muscles. Therefore, if the client's extremities are paralyzed, it indicates that the medication is effective in achieving the desired muscle relaxation necessary for mechanical ventilation. Choices B and C are incorrect as they suggest muscle activity, which would not be expected with the administration of a neuromuscular blocker. Choice D is unrelated to the effectiveness of tubocurarine chloride.

3. A patient with a diagnosis of deep vein thrombosis (DVT) is receiving heparin therapy. Which laboratory test should the nurse monitor to evaluate the effectiveness of the heparin therapy?

• A. Prothrombin time (PT)
• B. Partial thromboplastin time (PTT)
• C. Bleeding time
• D. Platelet count

Correct answer: B

Rationale: The correct answer is B: Partial thromboplastin time (PTT). Heparin affects the intrinsic pathway of the coagulation cascade, which is reflected by changes in the PTT. Monitoring the PTT helps ensure that the patient's blood is within the desired therapeutic range and prevents complications related to clotting or bleeding. Prothrombin time (PT) primarily assesses the extrinsic pathway and is not as sensitive to heparin therapy. Bleeding time and platelet count are not specific tests for monitoring the effectiveness of heparin therapy in DVT.

4. A 70-year-old woman presents with fatigue, anorexia, and weight loss. She has noticed darkening of her skin, particularly in sun-exposed areas. 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 combination of symptoms such as fatigue, anorexia, weight loss, hyperpigmentation of the skin, along with hyponatremia, hyperkalemia, and low cortisol levels, points towards Addison's disease. This condition is characterized by adrenal insufficiency, leading to a deficiency in cortisol and aldosterone production.

5. A healthcare provider is preparing to administer a scheduled dose of intravenous (IV) metoprolol (Lopressor) to a client. The client's apical pulse is 58 beats/minute. What action should the healthcare provider take?

• A. Administer the medication as prescribed.
• B. Hold the medication and notify the healthcare provider.
• C. Give half the prescribed dose and recheck the pulse in 30 minutes.
• D. Administer the medication and then recheck the pulse in 30 minutes.

Correct answer: B

Rationale: In the scenario described, with the client's apical pulse being 58 beats/minute, holding the medication and notifying the healthcare provider is the correct action. A low pulse rate may indicate bradycardia and may necessitate dose adjustment or further evaluation by the healthcare provider to prevent potential complications.
