1. Why is a low-protein diet recommended for a client with hepatic encephalopathy?
- A. Hyperglycemia
- B. Hypoglycemia
- C. Increased ammonia levels
- D. Electrolyte imbalance
Correct answer: C
Rationale: A low-protein diet is recommended for clients with hepatic encephalopathy to reduce ammonia levels. Ammonia, a byproduct of protein metabolism, can accumulate in the blood due to impaired liver function. Elevated ammonia levels can lead to worsening hepatic encephalopathy, a condition characterized by cognitive and neurological disturbances. Therefore, by limiting protein intake, the production of ammonia is reduced, thereby helping to manage hepatic encephalopathy. Choices A, B, and D are incorrect because hepatic encephalopathy is not primarily related to hyperglycemia, hypoglycemia, or electrolyte imbalance. The focus is on reducing ammonia levels to improve the condition.
2. A client admitted with a diagnosis of sepsis has a central venous pressure (CVP) of 15 mm Hg. What should the nurse do first?
- A. Administer a fluid bolus of 500 ml.
- B. Notify the healthcare provider immediately.
- C. Administer a diuretic.
- D. Continue to monitor the CVP.
Correct answer: B
Rationale: A CVP of 15 mm Hg is higher than normal, indicating possible fluid overload or heart failure, which needs immediate attention. Notifying the healthcare provider is crucial as they can evaluate the client's condition, order appropriate interventions, and prevent potential complications.
3. The nurse is caring for a client with a spinal cord injury. Which intervention should the nurse implement to prevent autonomic dysreflexia?
- A. Restrict the client's fluid intake.
- B. Keep the client's room warm.
- C. Ensure the client's bladder is emptied regularly.
- D. Limit the client's intake of high-fiber foods.
Correct answer: C
Rationale: To prevent autonomic dysreflexia in clients with spinal cord injuries, it is crucial to ensure the client's bladder is emptied regularly. Bladder distention is a common trigger for autonomic dysreflexia in these clients. Keeping the bladder empty helps prevent the complications associated with autonomic dysreflexia, such as dangerously high blood pressure. Choices A, B, and D are incorrect. Restricting fluid intake can lead to dehydration, keeping the room warm is not directly related to preventing autonomic dysreflexia, and limiting high-fiber foods is not a primary intervention for this condition.
4. A 40-year-old woman presents with fatigue, polyuria, and polydipsia. Laboratory tests reveal hyperglycemia and ketonuria. What is the most likely diagnosis?
- A. Type 1 diabetes mellitus
- B. Type 2 diabetes mellitus
- C. Diabetes insipidus
- D. Hyperthyroidism
Correct answer: A
Rationale: The combination of symptoms including fatigue, polyuria, polydipsia, along with laboratory findings of hyperglycemia and ketonuria strongly suggest type 1 diabetes mellitus. In type 1 diabetes mellitus, there is a deficiency of insulin leading to high blood sugar levels (hyperglycemia) and the breakdown of fats producing ketones, causing ketonuria. Type 2 diabetes mellitus typically presents differently and is more common in older individuals. Diabetes insipidus is characterized by excessive thirst and urination due to a deficiency of antidiuretic hormone, distinct from the provided clinical scenario. Hyperthyroidism may present with some overlapping symptoms like fatigue, but it does not account for the specific laboratory findings of hyperglycemia and ketonuria seen in this case.
5. A client with hypothyroidism is prescribed levothyroxine (Synthroid). Which instruction should the nurse provide?
- A. Take the medication with a meal.
- B. Take the medication at bedtime.
- C. Take the medication on an empty stomach.
- D. Take the medication with an antacid.
Correct answer: C
Rationale: The correct instruction for a client prescribed levothyroxine (Synthroid) is to take the medication on an empty stomach. This ensures optimal absorption of levothyroxine. Taking it with a meal can interfere with absorption due to food interactions. Taking it at bedtime may lead to inconsistent absorption as it should be taken at the same time every day in the morning. Taking it with an antacid can reduce the absorption of levothyroxine, making it less effective.
