1. Your patient has an order to receive Levothyroxine Sodium 75 mcg daily IV. You have a vial containing 100 mcg available from the pharmacy. According to the package insert, 5 mL of 0.9% sodium chloride is needed to reconstitute. You add the appropriate amount of sodium chloride to the vial. How many mcg of medication are in 1 mL of the vial?
- A. 20 mcg
- B. 15 mcg
- C. 25 mcg
- D. 30 mcg
Correct answer: A
Rationale: After reconstitution, the concentration of Levothyroxine Sodium in the vial is 100 mcg in 5 mL, which equals 20 mcg/mL. Therefore, in 1 mL of the vial, there are 20 mcg of medication.
2. 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.
3. The client has a nasogastric (NG) tube and is receiving enteral feedings. What intervention should the nurse implement to prevent complications associated with the NG tube?
- A. Flush the NG tube with water before and after feedings.
- B. Check gastric residual volume every 6 hours.
- C. Keep the head of the bed elevated at 30 degrees.
- D. Replace the NG tube every 24 hours.
Correct answer: C
Rationale: Keeping the head of the bed elevated at 30 degrees is crucial in preventing aspiration, a common complication associated with nasogastric (NG) tubes and enteral feedings. This position helps reduce the risk of reflux and aspiration of gastric contents into the lungs, promoting client safety and preventing respiratory complications. Flushing the NG tube with water before and after feedings (Choice A) is not the primary intervention to prevent complications. Checking gastric residual volume every 6 hours (Choice B) is important but not directly related to preventing complications associated with the NG tube. Replacing the NG tube every 24 hours (Choice D) is not a standard practice and is not necessary to prevent complications if the tube is functioning properly.
4. A 35-year-old woman presents with abdominal pain, diarrhea, and weight loss. She has a history of recurrent mouth ulcers and a perianal fistula. What is the most likely diagnosis?
- A. Ulcerative colitis
- B. Irritable bowel syndrome
- C. Crohn's disease
- D. Diverticulitis
Correct answer: C
Rationale: The combination of symptoms including recurrent mouth ulcers, perianal fistula, abdominal pain, diarrhea, and weight loss strongly suggests Crohn's disease. These extra-intestinal manifestations are characteristic of Crohn's disease, a chronic inflammatory condition that can affect any part of the gastrointestinal tract. Ulcerative colitis primarily involves the colon, while irritable bowel syndrome is a functional disorder without the inflammatory component seen in Crohn's disease. Diverticulitis typically presents with localized left lower quadrant pain and is less likely to cause mouth ulcers and perianal fistulas.
5. A 50-year-old man presents with fatigue, arthralgia, and darkening of the skin. Laboratory tests reveal elevated liver enzymes and high serum ferritin levels. What is the most likely diagnosis?
- A. Wilson's disease
- B. Hemochromatosis
- C. Alpha-1 antitrypsin deficiency
- D. Autoimmune hepatitis
Correct answer: B
Rationale: The symptoms of fatigue, arthralgia, and skin darkening, along with elevated liver enzymes and high serum ferritin levels, are characteristic of hemochromatosis, a condition characterized by iron overload. In hemochromatosis, excess iron is deposited in various organs, including the liver, leading to symptoms such as fatigue, joint pain, and skin pigmentation changes. The elevated liver enzymes and high serum ferritin levels seen in this patient further support the diagnosis of hemochromatosis.
