Nursing Elites

1. A client with a diagnosis of myocardial infarction (MI) is prescribed nitroglycerin. What is the primary action of this medication?

• A. Increases heart rate
• B. Lowers blood pressure
• C. Dilates coronary arteries
• D. Reduces myocardial oxygen demand

Correct answer: C

Rationale: The correct answer is C: Nitroglycerin dilates coronary arteries, improving blood flow to the heart muscle. This helps increase oxygen supply to the heart tissue. Option A, 'Increases heart rate,' is incorrect because nitroglycerin does not directly affect heart rate. Option B, 'Lowers blood pressure,' is also incorrect as while nitroglycerin can lower blood pressure, its primary action in the context of MI is related to coronary artery dilation. Option D, 'Reduces myocardial oxygen demand,' is not the primary action of nitroglycerin in the treatment of myocardial infarction; its main action is to increase oxygen supply by dilating coronary arteries.

2. The nurse is caring for a client with acute pancreatitis. Which intervention should be included in the plan of care?

• A. Provide a high-protein diet
• B. Encourage oral fluids
• C. Administer intravenous fluids as prescribed
• D. Monitor for signs of hyperglycemia

Correct answer: C

Rationale: The correct intervention to include in the plan of care for a client with acute pancreatitis is to administer intravenous fluids as prescribed. Intravenous fluids are crucial to maintain hydration and electrolyte balance in clients with acute pancreatitis. Providing a high-protein diet (Choice A) is not recommended initially for clients with acute pancreatitis, as they may need to be kept NPO (nothing by mouth) to rest the pancreas. Encouraging oral fluids (Choice B) may not be appropriate if the client is experiencing severe symptoms and requires intravenous fluids. Monitoring for signs of hyperglycemia (Choice D) is important but not the immediate intervention needed to address the fluid and electrolyte imbalances associated with acute pancreatitis.

3. The nurse plans to administer the rubella vaccine to a postpartum client whose titer is < 1:8 and who is breastfeeding. What information should the nurse provide this client?

• A. The client should bottle feed and pump her breast for 3 days following immunization
• B. The vaccine is given to produce maternal antibodies before lactation occurs
• C. The infant will receive immunization through the mother's breast milk
• D. The client should not get pregnant for 3 months after immunization

Correct answer: D

Rationale: Educating about the waiting period helps prevent possible rubella infection in a subsequent early pregnancy.

4. The nurse is caring for a client who has just returned from surgery with a urinary catheter in place. What is the most important action to prevent catheter-associated urinary tract infections (CAUTIs)?

• A. Irrigate the catheter daily
• B. Ensure the catheter bag is always below bladder level
• C. Change the catheter every 48 hours
• D. Administer prophylactic antibiotics

Correct answer: B

Rationale: The correct answer is to ensure the catheter bag is always below bladder level. This positioning helps prevent backflow of urine, reducing the risk of CAUTIs. Choice A, irrigating the catheter daily, is not recommended as it can introduce pathogens into the bladder. Changing the catheter too frequently (Choice C) can increase the risk of introducing pathogens. Administering prophylactic antibiotics (Choice D) is not the primary intervention for preventing CAUTIs and can lead to antibiotic resistance.

5. Which organ lies retroperitoneally?

• A. Kidneys
• B. Testicles
• C. Urinary bladder
• D. Pancreas

Correct answer: A

Rationale: The correct answer is A: Kidneys. The kidneys are located retroperitoneally, behind the peritoneum, providing structural protection and maintaining a stable position within the abdominal cavity. This location helps protect them from external physical trauma. Choices B, C, and D are incorrect because testicles, urinary bladder, and pancreas are not located retroperitoneally. Testicles are located in the scrotum, the urinary bladder is located in the pelvis, and the pancreas is located in the upper abdomen, not retroperitoneally.
