1. A 9-year-old female client was recently diagnosed with diabetes mellitus. Which symptom will her parents most likely report?
- A. Refuses to eat her favorite meals at home.
- B. Drinks more soft drinks than previously.
- C. Voids only one or two times per day.
- D. Gained 10 pounds within one month.
Correct answer: B
Rationale: The correct answer is B. Increased thirst and fluid intake, such as drinking more soft drinks than previously, is a common symptom of diabetes mellitus in children. This increased thirst is due to the body trying to eliminate excess sugar through urination, leading to dehydration and the need for more fluids. The other choices are less likely to be directly related to the diagnosis of diabetes mellitus in this scenario.
2. An otherwise healthy 45-year-old man presents with severe hematochezia and moderate abdominal cramping since this morning. A barium enema one year ago was normal. On examination, his blood pressure is 120/78 and pulse is 100 while lying; when standing, the blood pressure is 110/76 and pulse is 136. His hematocrit is 34. What is the most likely cause of bleeding?
- A. Diverticular bleed
- B. Duodenal ulcer
- C. Inflammatory bowel disease
- D. Vascular ectasia (watermelon stomach)
Correct answer: B
Rationale: The patient's presentation with hematochezia, moderate abdominal cramping, and hemodynamic changes (increased pulse on standing) suggests an upper gastrointestinal bleed. The drop in blood pressure and rise in pulse rate when standing indicate orthostatic hypotension, which is a sign of significant blood loss. The absence of melena does not rule out an upper GI bleed. Ulcers in the duodenal bulb can erode into the gastroduodenal artery, leading to brisk blood loss. A normal barium enema one year ago makes diverticular bleeding less likely. Inflammatory bowel disease usually does not cause severe acute GI bleeding unless there is ulceration into a vessel. Vascular ectasia, like watermelon stomach, typically presents with chronic blood loss and iron deficiency anemia, more common in older women. The absence of vomiting and the presence of hematochezia make Mallory-Weiss tear less likely in this case.
3. 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.
4. A 70-year-old woman presents with fatigue, anorexia, and weight loss. She has noticed darkening of her skin, particularly in sun-exposed areas. 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 combination of symptoms such as fatigue, anorexia, weight loss, hyperpigmentation of the skin, along with hyponatremia, hyperkalemia, and low cortisol levels, points towards Addison's disease. This condition is characterized by adrenal insufficiency, leading to a deficiency in cortisol and aldosterone production.
5. A patient with tuberculosis is started on rifampin. What advice should the nurse provide?
- A. Limit intake of green leafy vegetables.
- B. Expect orange-red discoloration of body fluids.
- C. Avoid exposure to sunlight.
- D. Take the medication with antacids.
Correct answer: B
Rationale: The correct advice for a patient starting rifampin is to expect orange-red discoloration of body fluids. Rifampin can cause harmless orange-red discoloration of body fluids, which may include urine, sweat, saliva, and tears. It is important for the patient to be aware of this side effect as it can stain clothing and contact lenses. Limiting the intake of green leafy vegetables is not necessary with rifampin. Avoiding exposure to sunlight is more commonly associated with other medications like tetracyclines, not rifampin. Taking rifampin with antacids is not recommended as antacids can reduce the absorption of rifampin, decreasing its effectiveness in treating tuberculosis.
