Nursing Elites

1. 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.

2. Following a CVA, the nurse assesses that a client has developed dysphagia, hypoactive bowel sounds, and a firm, distended abdomen. Which prescription for the client should the nurse question?

• A. Continuous tube feeding at 65 ml/hr via gastrostomy.
• B. Total parenteral nutrition to be infused at 125 ml/hour.
• C. Nasogastric tube connected to low intermittent suction.
• D. Metoclopramide (Reglan) intermittent piggyback.

Correct answer: A

Rationale: In a client with dysphagia and gastrointestinal symptoms such as hypoactive bowel sounds and a firm, distended abdomen, continuous tube feeding might exacerbate the symptoms. This can lead to complications and should be questioned by the nurse.

3. The nurse is planning care for a client with cirrhosis of the liver. Which intervention should the nurse include to reduce the risk of bleeding?

• A. Monitor for signs of infection.
• B. Limit the client's dietary protein intake.
• C. Administer vitamin K as prescribed.
• D. Encourage the client to increase fluid intake.

Correct answer: C

Rationale: Administering vitamin K as prescribed can help reduce the risk of bleeding in clients with cirrhosis by promoting clotting factor production. Cirrhosis often leads to impaired liver function, affecting the synthesis of clotting factors. Vitamin K supplementation helps in the production of these essential clotting factors, thus reducing the risk of bleeding in clients with cirrhosis. Monitoring for signs of infection (Choice A) is important for overall care but not directly related to reducing the risk of bleeding in cirrhosis. Limiting dietary protein intake (Choice B) may be necessary in some cases of cirrhosis but does not directly address the risk of bleeding. Encouraging increased fluid intake (Choice D) is beneficial for various aspects of health but does not specifically target the risk of bleeding in cirrhosis.

4. 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.

5. A client with a severe head injury is admitted to the intensive care unit (ICU). Which finding should the nurse report to the healthcare provider immediately?

• A. Urine output of 100 mL/hour.
• B. Intracranial pressure (ICP) of 20 mm Hg.
• C. Respiratory rate of 12 breaths/minute.
• D. Mean arterial pressure (MAP) of 70 mm Hg.

Correct answer: B

Rationale: An Intracranial Pressure (ICP) of 20 mm Hg is at the upper limit of normal and may indicate increased intracranial pressure, which is a critical finding in a client with a severe head injury. Elevated ICP can lead to further brain damage and must be addressed promptly to prevent complications such as herniation. Monitoring and managing ICP are crucial in the care of patients with head injuries in the ICU.
