Nursing Elites

1. A 32-year-old male with a complaint of dizziness has an order for Morphine via IV. What should the nurse do first?

• A. Check the patient's chest x-ray results.
• B. Retake vitals including blood pressure.
• C. Perform a neurological screening on the patient.
• D. Request the physician on-call to assess the patient.

Correct answer: B

Rationale: The correct first action for the nurse to take in this situation is to retake the patient's vitals, including blood pressure. Dizziness can be a sign of hypotension, which may be a contraindication for administering Morphine. Checking the chest x-ray results (Choice A) would not be the priority in this case as addressing the dizziness is more urgent. Performing a neurological screening (Choice C) may be important but not the first step when a patient presents with dizziness and an order for Morphine. Requesting the physician to assess the patient (Choice D) should come after the initial assessment and vitals retake.

2. The chemotherapeutic agent 5-fluorouracil (5-FU) is ordered for a client as an adjunct measure to surgery. Which statement about chemotherapy is true?

• A. It is a local treatment affecting only tumor cells.
• B. It is a systemic treatment affecting both tumor and normal cells.
• C. It has not yet been proven an effective treatment for cancer.
• D. It is often the drug of choice because it causes few, if any, side effects.

Correct answer: B

Rationale: The correct answer is that chemotherapy is a systemic treatment affecting both tumor and normal cells. 5-FU, as an antimetabolic drug, inhibits DNA synthesis and interferes with cell replication systemically. It affects all rapidly growing cells, including malignant and normal ones. This drug is used as adjuvant therapy for various cancers. Choice A is incorrect because chemotherapy affects both tumor and normal cells, not just tumor cells. Choice C is incorrect as chemotherapy has been proven effective in treating cancer. Choice D is incorrect because chemotherapy often causes side effects like bone marrow depression, anorexia, stomatitis, nausea, and vomiting.

3. What happens if folic acid is administered to treat anemia without determining its underlying cause?

• A. Erythropoiesis is inhibited
• B. Excessive levels of folic acid might accumulate, causing toxicity
• C. The symptoms of pernicious anemia might be masked, delaying treatment
• D. Intrinsic factor is destroyed

Correct answer: C

Rationale: When folic acid is given without determining the underlying cause of anemia, the symptoms of pernicious anemia may be masked, potentially delaying the correct treatment. Folic acid alone does not protect against the central nervous system changes seen in pernicious anemia, which are related to Vitamin B12 deficiency. Folic acid and Vitamin B12 are both crucial for cell growth and division. Administering folic acid without knowing the specific type of anemia could lead to a delay in addressing the root cause. Option A is incorrect because folic acid is essential for erythropoiesis, the production of red blood cells. Option B is incorrect as excessive folic acid can cause toxicity, but it is not the primary concern in this context. Option D is incorrect because folic acid treatment for anemia does not directly impact intrinsic factor, which is related to Vitamin B12 absorption.

4. Which of the following can certain foods like broccoli, oranges, dark greens, and dark yellow vegetables help improve?

• A. Vitamin intake
• B. Body functions
• C. Defense mechanisms
• D. Disease cure

Correct answer: C

Rationale: Certain foods like broccoli, oranges, dark greens, and dark yellow vegetables can help improve defense mechanisms by enhancing the immune system and overall health. While these foods can boost defense mechanisms, they are not a cure for diseases, do not balance body functions, and are not intended to solely supplement vitamin intake, which may be necessary in some cases. Therefore, the correct answer is defense mechanisms as these foods strengthen the body's ability to fight off illnesses and maintain health.

5. When administering intravenous electrolyte solution, which of the following precautions should the nurse take?

• A. Infuse hypertonic solutions cautiously.
• B. Mix no more than 60 mEq of potassium per liter of fluid.
• C. Prevent infiltration of calcium, which causes tissue necrosis and sloughing.
• D. Monitor the client's digitalis dosage for potential adjustments due to IV calcium administration.

Correct answer: C

Rationale: When administering intravenous electrolyte solutions, it is crucial to prevent infiltration of calcium to avoid tissue necrosis and sloughing. Hypertonic solutions should be infused cautiously (Choice A) to prevent adverse effects. The correct amount of potassium to be mixed in a liter of fluid is no more than 60 mEq, making Choice B incorrect. While monitoring the client's digitalis dosage for potential adjustments due to IV calcium administration is important, the statement suggesting an increased dosage is incorrect as IV calcium diminishes digitalis's action, making Choice D incorrect.
