Nursing Elites

1. A client with liver failure is at an increased risk of bleeding due to the inability to synthesize prothrombin in the liver. What factor most likely contributes to this loss of function?

• A. Alterations in glucose metabolism
• B. Retention of bile salts
• C. Inadequate production of albumin by hepatocytes
• D. Inability of the liver to use vitamin K

Correct answer: D

Rationale: The correct answer is D. The liver's inability to use vitamin K is the most likely factor contributing to the loss of prothrombin synthesis in liver failure. Vitamin K is essential for the synthesis of prothrombin, a crucial clotting factor. In liver failure, impaired utilization of vitamin K leads to decreased production of prothrombin, increasing the risk of bleeding in affected individuals.

2. When assessing a male client who is receiving a unit of packed red blood cells (PRBCs), the nurse notes that the infusion was started 30 minutes ago, and 50 ml of blood is left to be infused. The client's vital signs are within normal limits. He reports feeling 'out of breath' but denies any other complaints. What action should the nurse take at this time?

• A. Administer a PRN prescription for diphenhydramine (Benadryl).
• B. Start the normal saline attached to the Y-tubing at the same rate.
• C. Decrease the intravenous flow rate of the PRBC transfusion.
• D. Ask the respiratory therapist to administer PRN albuterol (Ventolin).

Correct answer: C

Rationale: In this scenario, the client is experiencing symptoms of shortness of breath, which could indicate fluid overload from the PRBC transfusion. By decreasing the intravenous flow rate of the transfusion, the nurse can slow down the rate of blood being infused, potentially alleviating the symptoms of fluid overload and shortness of breath. This intervention can help prevent further complications and promote the client's comfort and safety.

3. A 50-year-old man presents with progressive jaundice, dark urine, and pruritus. Imaging reveals a mass in the head of the pancreas. What is the most likely diagnosis?

• A. Pancreatic cancer
• B. Chronic pancreatitis
• C. Gallstones
• D. Primary sclerosing cholangitis

Correct answer: A

Rationale: The presentation of progressive jaundice, dark urine, and pruritus along with a pancreatic mass, particularly in the head of the pancreas, strongly suggests pancreatic cancer as the most likely diagnosis. These symptoms are classic for obstructive jaundice caused by a mass in the head of the pancreas, making pancreatic cancer the most fitting choice.

4. A 35-year-old woman presents with fatigue, weight gain, and cold intolerance. Laboratory tests reveal high TSH and low free T4 levels. What is the most likely diagnosis?

• A. Hypothyroidism
• B. Hyperthyroidism
• C. Thyroiditis
• D. Thyroid cancer

Correct answer: A

Rationale: The scenario describes a 35-year-old woman with symptoms of fatigue, weight gain, and cold intolerance along with high TSH and low free T4 levels. These findings are consistent with the diagnosis of hypothyroidism. In hypothyroidism, there is decreased thyroid hormone production leading to elevated TSH levels as the body tries to stimulate the thyroid to produce more hormone. The low free T4 levels indicate insufficient thyroid hormone in the blood, which can manifest as symptoms such as fatigue, weight gain, and cold intolerance.

5. A patient with epilepsy is prescribed phenytoin. What is the primary side effect the nurse should monitor for?

• A. Hypotension
• B. Gingival hyperplasia
• C. Bradycardia
• D. Hyperkalemia

Correct answer: B

Rationale: Gingival hyperplasia, or overgrowth of the gums, is a common side effect of phenytoin. Patients should maintain good oral hygiene to minimize this effect.
