Nursing Elites

1. The healthcare provider is caring for a patient who is taking warfarin (Coumadin). Which laboratory value should the healthcare provider monitor closely?

• A. Platelet count.
• B. Prothrombin time (PT).
• C. Hemoglobin level.
• D. White blood cell count.

Correct answer: B

Rationale: Corrected Rationale: When caring for a patient on warfarin, monitoring prothrombin time (PT) is crucial. PT helps assess the blood's ability to clot properly, ensuring the patient maintains therapeutic anticoagulation levels while minimizing bleeding risks. Platelet count (Choice A) is important but not the most critical for warfarin therapy. Hemoglobin level (Choice C) and white blood cell count (Choice D) are not directly related to monitoring the effects of warfarin.

2. A patient with chronic pain is prescribed gabapentin. What is the primary purpose of this medication?

• A. Relieve neuropathic pain
• B. Reduce inflammation
• C. Enhance opioid analgesia
• D. Suppress cough

Correct answer: A

Rationale: Gabapentin is primarily prescribed to relieve neuropathic pain. It works by stabilizing electrical activity in the nerves, making it effective in managing conditions such as diabetic neuropathy, postherpetic neuralgia, and other forms of chronic pain originating from nerve damage.

3. What is/are the possible cause(s) of acute pancreatitis in this patient?

• A. HIV
• B. Cytomegalovirus
• C. Dideoxyinosine (ddI)
• D. Pentamidine

Correct answer: B

Rationale: This patient presents with symptoms and lab findings consistent with acute pancreatitis. Cytomegalovirus is a common viral infection associated with pancreatitis. In patients with AIDS, the pancreas can be affected by various infections (e.g., cryptococcus, Mycobacterium tuberculosis, candida, Toxoplasma gondii) and medications (such as ddI, pentamidine, trimethoprim/sulfamethoxazole, metronidazole) can also lead to acute pancreatitis. While HIV infection predisposes individuals to various opportunistic infections, in this case, the most likely cause of the acute pancreatitis is cytomegalovirus infection.

4. Which of the following statements about Helicobacter pylori (H. pylori) is false?

• A. H. pylori does not invade the gastric or duodenal epithelium
• B. H. pylori stimulates gastric acid secretion
• C. Eradication of H. pylori prevents adenocarcinoma of the stomach
• D. H. pylori produces a urease that splits urea into ammonia and CO2

Correct answer: C

Rationale: H. pylori is known to reside in the mucus layer of the stomach and does not invade the epithelium. It produces urease that splits urea into ammonia and CO2. This action helps in neutralizing the acidic environment and allows H. pylori to survive. Additionally, urease activity can be detected in diagnostic tests for H. pylori. The stimulation of gastric acid secretion and disruption of the protective mucus layer are mechanisms by which H. pylori promotes injury. While eradicating H. pylori infection has been associated with a decreased risk of developing gastric cancer, it does not prevent adenocarcinoma of the stomach entirely.

5. A client with peptic ulcer disease is prescribed omeprazole (Prilosec). Which instruction should the nurse include in the client's teaching plan?

• A. Take the medication with food.
• B. Take the medication at bedtime.
• C. Take the medication on an empty stomach.
• D. Take the medication as needed for pain relief.

Correct answer: C

Rationale: The correct instruction for a client prescribed omeprazole (Prilosec) is to take the medication on an empty stomach. This is important for optimal absorption and effectiveness of the medication in treating peptic ulcer disease. Choice A ('Take the medication with food') is incorrect because omeprazole should be taken on an empty stomach. Choice B ('Take the medication at bedtime') is incorrect as it does not align with the optimal timing for omeprazole administration. Choice D ('Take the medication as needed for pain relief') is incorrect because omeprazole is not typically used for immediate pain relief but rather for long-term management of peptic ulcer disease.
