Nursing Elites

1. What electrolyte value should be monitored when a patient is receiving a loop diuretic?

• A. Calcium levels
• B. Phosphorus levels
• C. Potassium levels
• D. Magnesium levels

Correct answer: C

Rationale: When a patient is receiving a loop diuretic like furosemide (Lasix), potassium levels should be monitored closely. Loop diuretics act on the ascending loop of Henle to inhibit the reabsorption of sodium and water, leading to potassium loss. Monitoring potassium levels is crucial to prevent hypokalemia, which can result in serious complications such as cardiac arrhythmias. Calcium levels (Choice A), phosphorus levels (Choice B), and magnesium levels (Choice D) are not typically affected directly by loop diuretics and do not require routine monitoring in this context.

2. A nurse teaches a client who is being discharged home with a peripherally inserted central catheter (PICC). Which statement should the nurse include in this clients teaching?

• A. avoid carrying your grandchild with the arm that has the central catheter.
• B. Be sure to place the arm with the central catheter in a sling during the day
• C. Flush the peripherally inserted central catheter line with normal saline daily.
• D. You can use the arm with the central catheter for most activities of daily living.

Correct answer: A

Rationale:

3. Which negative ion is most important in intracellular fluid?

• A. Phosphate ions.
• B. Protein molecules.
• C. Chlorine.
• D. Phosphate ions and protein molecules.

Correct answer: D

Rationale: Intracellular fluid contains phosphate ions and protein molecules as essential anions. Phosphate ions play a crucial role in various cellular processes, including energy transfer. Proteins, being large molecules with negative charges, also contribute significantly to the negative ion concentration within cells. Chlorine is primarily an extracellular anion and is not as prominent as phosphate ions and proteins within intracellular fluid, making it a less important negative ion in this context. Therefore, the correct answer is D because both phosphate ions and protein molecules are crucial negative ions in intracellular fluid.

4. A nurse is caring for a client who is having a subclavian central venous catheter inserted. The client begins to report chest pain and difficulty breathing. After administering oxygen, which action should the nurse take next?

• A. Administer a sublingual nitroglycerin tablet
• B. Prepare to assist with chest tube insertion.
• C. . Place a sterile dressing over the IV site
• D. Re-position the client into the Trendelenburg position.

Correct answer: B

Rationale:

5. You are caring for a 65-year-old male patient admitted to your medical unit 72 hours ago with pyloric stenosis. A nasogastric tube placed upon admission has been on low intermittent suction ever since. Upon review of the mornings blood work, you notice that the patients potassium is below reference range. You should recognize that the patient may be at risk for what imbalance?

• A. Hypercalcemia
• B. Metabolic acidosis
• C. Metabolic alkalosis
• D. Respiratory acidosis

Correct answer: C
