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. Before administering an antibiotic that can cause nephrotoxicity, which lab value is most important for the PN to review?

• A. Hemoglobin and Hematocrit
• B. Serum Calcium
• C. Serum Creatinine
• D. WBC

Correct answer: C

Rationale: Serum creatinine is the most important lab value to review before administering an antibiotic that can cause nephrotoxicity. This is because serum creatinine is a key indicator of kidney function. An elevated serum creatinine level may indicate impaired renal function, and administering nephrotoxic drugs in such situations can further damage the kidneys. Monitoring serum creatinine levels helps healthcare providers assess renal function and make informed decisions regarding drug administration. Choices A, B, and D are not as directly related to kidney function and nephrotoxicity, making them less crucial in this scenario. Hemoglobin and hematocrit levels assess for anemia, serum calcium levels are more related to bone health and nerve function, and WBC count is associated with immune response, none of which directly reflect kidney function or the risk of nephrotoxicity.

3. 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.

4. An adult client is undergoing weekly external radiation treatments for breast cancer and reports increasing fatigue. What action should the nurse take?

• A. Notify the healthcare provider or charge nurse immediately
• B. Offer to reschedule the treatment for the following week
• C. Plan to monitor the client's vital signs every 30 minutes
• D. Reinforce the need for extra rest periods and plenty of sleep

Correct answer: D

Rationale: The correct action for the nurse to take when a client undergoing radiation treatment for breast cancer reports increasing fatigue is to reinforce the need for extra rest periods and plenty of sleep. Fatigue is a common side effect of radiation therapy, and adequate rest and sleep can help manage this symptom. Notifying the healthcare provider or charge nurse immediately (choice A) is not necessary for increasing fatigue, as it is expected during radiation therapy. Offering to reschedule the treatment for the following week (choice B) is not the best initial action for managing fatigue. Planning to monitor the client's vital signs every 30 minutes (choice C) is unnecessary and not directly related to managing fatigue caused by radiation therapy.

5. Which of the following is a primary intervention for a patient experiencing hypoglycemia?

• A. Administering insulin
• B. Providing a complex carbohydrate meal
• C. Giving 15 grams of a fast-acting carbohydrate, like glucose tablets
• D. Encouraging the patient to exercise

Correct answer: C

Rationale: Giving 15 grams of a fast-acting carbohydrate, such as glucose tablets, is the primary intervention for hypoglycemia. This rapid-acting carbohydrate helps quickly raise blood sugar levels, providing immediate relief to the patient. Administering insulin (Choice A) would further lower blood sugar levels, exacerbating the hypoglycemia. Providing a complex carbohydrate meal (Choice B) would not act quickly enough to address the immediate low blood sugar issue. Encouraging the patient to exercise (Choice D) is inappropriate during hypoglycemia as it can further deplete glucose levels.
