Nursing Elites

1. A client with cirrhosis is at risk for bleeding. Which laboratory test is most important to monitor?

• A. Blood glucose
• B. Serum creatinine
• C. Prothrombin time (PT)
• D. Electrolytes

Correct answer: C

Rationale: In clients with cirrhosis, monitoring the Prothrombin time (PT) is crucial as it assesses the blood's ability to clot. Cirrhosis can lead to impaired liver function, affecting the synthesis of clotting factors, hence increasing the risk of bleeding. Maintaining a close watch on PT levels helps in timely intervention to prevent excessive bleeding episodes. Blood glucose (Choice A) is not directly related to the clotting function; serum creatinine (Choice B) and electrolytes (Choice D) are important, but in cirrhosis, monitoring PT takes precedence due to the increased bleeding risk.

2. What instructions should the nurse give to a patient with cervical cancer who is planned to receive external-beam radiation to prevent complications from the effects of the radiation?

• A. Test stools for the presence of blood.
• B. Maintain a low-residue, high-fiber diet.
• C. Clean the perianal area carefully after every bowel movement.
• D. Inspect the mouth and throat daily for signs of thrush.

Correct answer: C

Rationale: When a patient with cervical cancer is receiving external-beam radiation, the radiation to the abdomen can affect organs in its path, such as the bowel, leading to complications like frequent diarrhea. Cleaning the perianal area carefully after each bowel movement is crucial to decrease the risk of skin breakdown and infection. Testing stools for blood is not necessary since inflammation associated with radiation may lead to occult blood in stools. Maintaining a low-residue diet is actually recommended to prevent bowel irritation. Radiation to the abdomen does not cause stomatitis, so inspecting the mouth and throat for thrush is not directly related to the effects of external-beam radiation in this context.

3. A patient with hyperthyroidism is prescribed propylthiouracil (PTU). What is the primary purpose of this medication?

• A. Increase thyroid hormone production
• B. Suppress thyroid hormone production
• C. Enhance iodine absorption
• D. Stimulate the thyroid gland

Correct answer: B

Rationale: Propylthiouracil (PTU) is a medication used to treat hyperthyroidism by suppressing the production of thyroid hormones. It works by inhibiting the enzyme responsible for the synthesis of thyroid hormones, thereby reducing their levels in the body. This helps to alleviate the symptoms of hyperthyroidism and restore thyroid hormone levels to normal range.

4. A 50-year-old man presents with severe epigastric pain radiating to his back, nausea, and vomiting. He has a history of heavy alcohol use. Laboratory tests reveal elevated serum amylase and lipase. What is the most likely diagnosis?

• A. Acute cholecystitis
• B. Peptic ulcer disease
• C. Acute pancreatitis
• D. Gastroesophageal reflux disease

Correct answer: C

Rationale: The patient's history of heavy alcohol use, severe epigastric pain radiating to the back, nausea, vomiting, and elevated serum amylase and lipase levels are classic signs of acute pancreatitis. Alcohol consumption is a common predisposing factor for pancreatitis, leading to inflammation of the pancreas. The clinical presentation, along with the laboratory findings, strongly support the diagnosis of acute pancreatitis in this patient.

5. A client with a history of atrial fibrillation is prescribed warfarin (Coumadin). Which laboratory test should the nurse monitor to determine the effectiveness of the medication?

• A. Platelet count.
• B. Prothrombin time (PT) and international normalized ratio (INR).
• C. Activated partial thromboplastin time (aPTT).
• D. Fibrinogen level.

Correct answer: B

Rationale: Prothrombin time (PT) and international normalized ratio (INR) are essential laboratory tests to monitor the effectiveness of warfarin (Coumadin) therapy. These tests help assess the clotting time and the desired anticoagulant effect of the medication. Monitoring PT and INR levels is crucial to ensure that the client is within the therapeutic range, reducing the risk of bleeding or clotting complications associated with warfarin therapy. Platelet count (Choice A) measures the number of platelets in the blood and is not specific for monitoring warfarin therapy. Activated partial thromboplastin time (aPTT) (Choice C) is more commonly used to monitor heparin therapy, not warfarin. Fibrinogen level (Choice D) assesses the amount of fibrinogen in the blood and is not a specific test for monitoring warfarin therapy.
