Nursing Elites

1. What is the function of the enzyme lactase in the digestive system?

• A. Breaks down lactose into glucose and galactose
• B. Breaks down proteins into amino acids
• C. Converts starch into maltose
• D. Breaks down fats into fatty acids

Correct answer: A

Rationale: The correct answer is A: 'Breaks down lactose into glucose and galactose.' Lactase is an enzyme in the small intestine that specifically breaks down lactose, the sugar found in milk, into glucose and galactose for absorption. Choice B is incorrect because proteins are broken down into amino acids by protease enzymes. Choice C is incorrect because the enzyme amylase converts starch into maltose. Choice D is incorrect as lipase enzymes break down fats into fatty acids.

2. What is the most effective method to prevent medication errors during administration?

• A. Relying on memory for medication dosages
• B. Using a bar-code medication administration system
• C. Administering medications as quickly as possible to avoid delays
• D. Allowing another individual to administer medications

Correct answer: B

Rationale: Using a bar-code medication administration system is the best method to prevent medication errors during administration. This system verifies medication details electronically, ensuring that the correct medication is given to the right patient. Relying on memory for medication dosages (choice A) is not recommended as it can lead to errors. Administering medications quickly (choice C) may increase the risk of mistakes due to haste. Allowing another individual (choice D) to administer medications does not address the root cause of preventing errors during administration.

3. A child with glomerulonephritis is admitted in the acute edematous phase. Based on this diagnosis, which nursing intervention should the nurse plan to include in the child's plan of care?

• A. Recommend parents bring favorite snacks
• B. Encourage ambulation daily to the playroom
• C. Measure blood pressure every 4 to 6 hours
• D. Offer a selection of fresh fruit for each meal

Correct answer: C

Rationale: The correct answer is to measure blood pressure every 4 to 6 hours. Monitoring blood pressure frequently is crucial in managing glomerulonephritis, as hypertension is a common complication during the acute edematous phase. Choice A is incorrect as it does not address the specific needs of a child with glomerulonephritis. Choice B is incorrect as excessive activity may not be suitable during the acute phase, as rest and monitoring are more important. Choice D is incorrect as the focus should be on monitoring vital signs rather than meal options.

4. A post-operative client develops a sudden onset of chest pain and dyspnea. The nurse suspects a pulmonary embolism (PE). What is the priority nursing action?

• A. Administer oxygen via face mask.
• B. Elevate the client's legs.
• C. Prepare the client for immediate surgery.
• D. Notify the healthcare provider immediately.

Correct answer: A

Rationale: Administering oxygen via face mask is the priority nursing action in a post-operative client suspected of a pulmonary embolism. This intervention helps ensure adequate oxygenation while further assessments and interventions are initiated. Elevating the client's legs is not indicated for a suspected pulmonary embolism; it is more appropriate for conditions like shock. Immediate surgery is not the priority in this situation as the client is experiencing acute symptoms requiring prompt intervention. While notifying the healthcare provider is important, the immediate focus should be on providing oxygen to the client to support respiratory function.

5. A client is complaining of a tingling sensation in the fingers, nose tip, and earlobes 24 hours after a total thyroidectomy. Which measure should the PN implement first?

• A. Apply sequential compression devices bilaterally
• B. Initiate prescribed L-thyroxine replacement therapy
• C. Obtain prescribed calcium gluconate for tetany
• D. Prepare for emergency tracheotomy at the bedside

Correct answer: C

Rationale: The correct answer is C: Obtain prescribed calcium gluconate for tetany. Tingling sensations post-thyroidectomy may indicate hypocalcemia, a potential complication that requires prompt treatment with calcium gluconate to prevent tetany. Initiating L-thyroxine replacement therapy (choice B) is important but not the first priority in this situation. Applying sequential compression devices (choice A) is not indicated for tingling sensations and does not address the potential complication of hypocalcemia. Preparing for an emergency tracheotomy (choice D) is not warranted based on the client's symptoms of tingling sensations.
