1. 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.
2. A client with coronary artery disease (CAD) is prescribed atorvastatin (Lipitor). Which laboratory value requires immediate intervention?
- A. Total cholesterol of 180 mg/dL.
- B. Low-density lipoprotein (LDL) of 200 mg/dL.
- C. Triglycerides of 150 mg/dL.
- D. High-density lipoprotein (HDL) of 40 mg/dL.
Correct answer: B
Rationale: An LDL level of 200 mg/dL is significantly elevated and requires immediate intervention to reduce the risk of cardiovascular events in a client with coronary artery disease (CAD). High LDL levels contribute to the development and progression of atherosclerosis, which can lead to complications like heart attacks and strokes. Lowering LDL levels is a key goal in managing CAD and preventing further cardiovascular damage. Total cholesterol of 180 mg/dL, triglycerides of 150 mg/dL, and HDL of 40 mg/dL are within acceptable ranges and do not pose an immediate risk that necessitates urgent intervention.
3. 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.
4. The patient described in the preceding question has a positive H. pylori antibody blood test. She is compliant with the medical regimen you prescribe. Although her symptoms initially respond, she returns to see you six months later with the same symptoms. Which of the following statements is correct?
- A. She is at low risk for reinfection with H. pylori
- B. A positive serum IgG indicates that eradication of H. pylori was successful
- C. The urease breath test is an ideal test to document failure of eradication
- D. Dyspepsia typically worsens with H. pylori eradication
Correct answer: C
Rationale: Reinfection with H. pylori is rare, and the persistence of infection usually indicates poor compliance with the medical regimen or antibiotic resistance. The serum IgG may remain positive indefinitely and cannot be used to determine failure of eradication; however, a decrease in quantitative IgG levels has been utilized to indicate treatment success. If available, either the stool antigen or urease breath test is ideal to document treatment failure due to their high sensitivity, specificity, and ease of performance. The relationship between dyspepsia and H. pylori is controversial, but generally, dyspepsia does not typically improve with H. pylori eradication.
5. A 35-year-old man presents with fatigue, weight loss, and hyperpigmentation of the skin. 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 clinical presentation of a 35-year-old man with fatigue, weight loss, hyperpigmentation of the skin, hyponatremia, hyperkalemia, and low cortisol levels is classic for Addison's disease. These findings are consistent with primary adrenal insufficiency, where the adrenal glands fail to produce adequate cortisol. In Addison's disease, the adrenal cortex is damaged, leading to decreased cortisol production and elevated levels of ACTH. This results in symptoms such as fatigue, weight loss, and hyperpigmentation due to increased ACTH production stimulating melanocytes. Hyponatremia and hyperkalemia are common electrolyte abnormalities seen in Addison's disease due to aldosterone deficiency. Therefore, the correct diagnosis in this case is Addison's disease.
