Nursing Elites

1. A client has a prescription for a Transcutaneous Electrical Nerve Stimulator (TENS) unit for pain management during the postoperative period following a Lumbar Laminectomy. What information should the nurse reinforce about the action of this adjuvant pain modality?

• A. Mild electrical stimulus on the skin surface closes the gates of nerve conduction for severe pain
• B. Pain perception in the cerebral cortex is dulled by the unit's discharge of an electrical stimulus
• C. An infusion of medication in the spinal canal will block pain perception
• D. The discharge of electricity will distract the client's focus on the pain

Correct answer: A

Rationale: The correct answer is A. TENS units work by delivering small electrical impulses through the skin. These impulses are thought to close the 'gates of nerve conduction,' which can help in managing severe pain. Choice B is incorrect because the dulled pain perception does not occur in the cerebral cortex by the TENS unit. Choice C is incorrect as it describes a different method of pain management involving medication in the spinal canal. Choice D is incorrect because TENS does not work by distracting the client's focus on pain, but rather by altering pain perception through electrical impulses.

2. The nurse is assessing a client with left-sided heart failure. Which symptom should the nurse expect to find?

• A. Peripheral edema
• B. Jugular vein distention
• C. Shortness of breath
• D. Weight gain

Correct answer: C

Rationale: Shortness of breath is a characteristic symptom of left-sided heart failure. In this condition, the heart's inability to effectively pump blood forward causes blood to back up into the lungs, leading to fluid accumulation. This fluid accumulation results in pulmonary congestion, manifesting as shortness of breath or difficulty breathing. Peripheral edema (choice A) is more commonly associated with right-sided heart failure, where fluid accumulates in the extremities. Jugular vein distention (choice B) is a sign of increased central venous pressure and is more indicative of right-sided heart failure. Weight gain (choice D) can be a general symptom of heart failure due to fluid retention, but shortness of breath is specifically related to left-sided heart failure.

3. A client with heart failure is prescribed a low-sodium diet. The nurse notices the client's meal tray contains high-sodium foods. What action should the nurse take?

• A. Educate the client about the importance of a low-sodium diet
• B. Replace the meal with a low-sodium option
• C. Report the error to the dietary department
• D. Encourage the client to avoid eating the high-sodium foods

Correct answer: B

Rationale: The correct action for the nurse to take in this situation is to replace the high-sodium meal with a low-sodium option. This immediate intervention ensures that the client adheres to the prescribed low-sodium diet, crucial for managing heart failure and preventing fluid retention. Educating the client (Choice A) about the diet is important but not as urgent as ensuring they receive the correct meal. Reporting the error to the dietary department (Choice C) can be done after addressing the immediate issue. Encouraging the client to avoid high-sodium foods (Choice D) is not as effective as replacing the current meal with a suitable alternative.

4. A client with a diagnosis of chronic kidney disease (CKD) is receiving epoetin alfa (Epogen). What is the primary goal of this medication?

• A. To reduce the risk of bleeding.
• B. To lower blood pressure.
• C. To stimulate red blood cell production.
• D. To increase appetite.

Correct answer: C

Rationale: The correct answer is C: 'To stimulate red blood cell production.' Epoetin alfa, such as Epogen, is used to treat anemia by stimulating red blood cell production in clients with chronic kidney disease. This medication helps increase hemoglobin levels and reduce the need for blood transfusions. Option A, 'To reduce the risk of bleeding,' is incorrect as epoetin alfa does not directly impact bleeding risk. Option B, 'To lower blood pressure,' is incorrect as epoetin alfa is not indicated for blood pressure management. Option D, 'To increase appetite,' is also incorrect as the primary goal of epoetin alfa is related to improving anemia by boosting red blood cell production.

5. A client is prescribed metformin for the management of type 2 diabetes. What is the primary action of this medication?

• A. Stimulates insulin secretion from the pancreas.
• B. Increases insulin sensitivity in various tissues.
• C. Decreases hepatic glucose production.
• D. Delays absorption of glucose from the intestines.

Correct answer: C

Rationale: The correct answer is C: Decreases hepatic glucose production. Metformin primarily works by reducing the production of glucose in the liver (hepatic glucose production) and by improving insulin sensitivity in various tissues. Choice A is incorrect as metformin does not stimulate insulin secretion from the pancreas. Choice B is incorrect as metformin increases insulin sensitivity in various tissues, not just muscle cells. Choice D is incorrect as metformin does not delay glucose absorption from the intestines.
