Nursing Elites

1. A client is receiving lidocaine IV at 3 mg/minute. The pharmacy dispenses a 500 ml IV solution of normal saline (NS) with 2 grams of lidocaine. The nurse should regulate the infusion pump to deliver how many ml/hour?

• A. 18
• B. 27
• C. 36
• D. 45

Correct answer: D

Rationale: The infusion rate is calculated based on the concentration of lidocaine and the prescribed rate of infusion. First, convert lidocaine's weight to milligrams (2 grams = 2000 mg). Then, use the formula: (Total volume in ml * dose in mg) / 60 minutes. For this case, (500 ml * 2000 mg) / 60 minutes = 45 ml/hour. Therefore, the correct answer is D. Choices A, B, and C are incorrect as they do not reflect the accurate calculation based on the provided concentration and infusion rate.

2. A child with heart failure (HF) is taking digitalis. Which sign indicates to the nurse that the child may be experiencing digitalis toxicity?

• A. Tachycardia
• B. Dyspnea
• C. Vomiting
• D. Muscle cramps

Correct answer: C

Rationale: Vomiting is a common sign of digitalis toxicity and should be closely monitored. While tachycardia is a common sign of heart failure, it is not typically associated with digitalis toxicity (Choice A). Dyspnea (Choice B) and muscle cramps (Choice D) are not specific signs of digitalis toxicity and can be present in other conditions. Therefore, the presence of vomiting should raise concerns about digitalis toxicity in the child with heart failure.

3. A client is admitted to a medical unit with the diagnosis of gastritis and chronic heavy alcohol abuse. What should the nurse administer to prevent the development of Wernicke's syndrome?

• A. Lorazepam (Ativan)
• B. Famotidine (Pepcid)
• C. Thiamine (Vitamin B1)
• D. Atenolol (Tenormin)

Correct answer: C

Rationale: Thiamine supplementation is critical in preventing Wernicke's syndrome, especially in clients with chronic alcohol use. Wernicke's syndrome is a neurological disorder caused by thiamine deficiency. Lorazepam is a benzodiazepine used for anxiety and not for preventing Wernicke's syndrome. Famotidine is an H2 blocker used to reduce stomach acid production but does not prevent Wernicke's syndrome. Atenolol is a beta-blocker used for hypertension and angina, not for preventing Wernicke's syndrome.

4. What intervention should the nurse implement during the administration of a vesicant chemotherapeutic agent via an IV site in the client's arm?

• A. Assess IV site frequently for signs of extravasation
• B. Monitor capillary refill distal to the infusion site
• C. Apply a topical anesthetic at the infusion site for burning
• D. Explain that temporary burning at the IV site may occur

Correct answer: A

Rationale: The correct intervention the nurse should implement during the administration of a vesicant chemotherapeutic agent via an IV site in the client's arm is to assess the IV site frequently for signs of extravasation. Vesicants are agents that can cause tissue damage if they leak into the surrounding tissues. Monitoring for signs of extravasation such as swelling, pain, or redness is crucial to prevent tissue damage and ensure prompt intervention if extravasation occurs. Choices B, C, and D are incorrect because monitoring capillary refill, applying a topical anesthetic for burning, and explaining temporary burning do not directly address the risk of extravasation associated with vesicant chemotherapeutic agents.

5. To evaluate the client's therapeutic response to lactulose for signs of hepatic encephalopathy, which assessment should the nurse obtain?

• A. Level of consciousness
• B. Percussion of abdomen
• C. Serum electrolytes
• D. Blood glucose

Correct answer: A

Rationale: The correct answer is A: Level of consciousness. Monitoring the client's level of consciousness is essential in evaluating the effectiveness of lactulose in treating hepatic encephalopathy. Lactulose helps reduce blood ammonia levels by promoting the excretion of ammonia in the stool, thereby improving the client's mental status. Assessing the client's level of consciousness helps determine if the medication is effectively managing hepatic encephalopathy symptoms. Choices B, percussion of the abdomen, and D, blood glucose, are not directly related to evaluating the therapeutic response to lactulose for hepatic encephalopathy. Choice C, serum electrolytes, while important in overall patient care, is not the primary assessment to determine lactulose's effectiveness in treating hepatic encephalopathy.
