Nursing Elites

1. Which medication should the nurse withhold if the client's serum potassium level is 6.2 mEq/L?

• A. Losartan
• B. Spironolactone
• C. Metoprolol
• D. Furosemide

Correct answer: B

Rationale: The correct answer is B: Spironolactone. Spironolactone is a potassium-sparing diuretic that can lead to hyperkalemia. With potassium levels already elevated at 6.2 mEq/L, withholding Spironolactone is essential to prevent further increase in potassium levels, which could result in dangerous cardiac arrhythmias. Losartan (Choice A) is an angiotensin receptor blocker and does not directly affect potassium levels. Metoprolol (Choice C) is a beta-blocker and also does not impact potassium levels significantly. Furosemide (Choice D) is a loop diuretic that can actually lower potassium levels, so it would not be the medication to withhold in this case.

2. A client with deep vein thrombosis (DVT) is prescribed warfarin. What lab value should the nurse review before administering the medication?

• A. Prothrombin time (PT)
• B. Hemoglobin and hematocrit (H&H)
• C. International Normalized Ratio (INR)
• D. Partial thromboplastin time (PTT)

Correct answer: C

Rationale: The correct answer is C: International Normalized Ratio (INR). Before administering warfarin to a client with deep vein thrombosis, the nurse should review the INR to ensure the client is within the therapeutic range. INR is specifically monitored for patients on warfarin therapy to assess the clotting ability of the blood. Choices A, B, and D are incorrect as they are not the primary lab value used to monitor warfarin therapy. Prothrombin time (PT) is used to measure how long blood takes to clot. Hemoglobin and hematocrit (H&H) assess for anemia and the blood's oxygen-carrying capacity. Partial thromboplastin time (PTT) is used to monitor heparin therapy, not warfarin.

3. An older adult client is admitted with pneumonia and prescribed penicillin G potassium. Which factor increases the risk of an adverse reaction?

• A. Sputum culture showing Streptococcus pneumoniae.
• B. Previous treatment with penicillin.
• C. Daily use of spironolactone for hypertension.
• D. Documented allergy to sulfa drugs.

Correct answer: C

Rationale: The correct answer is C. Daily use of spironolactone for hypertension can increase the risk of hyperkalemia and interact with penicillin, leading to adverse reactions. Choice A is incorrect because the sputum culture showing Streptococcus pneumoniae is an expected finding in a patient with pneumonia and does not increase the risk of an adverse reaction to penicillin. Choice B is incorrect as previous treatment with penicillin does not necessarily increase the risk of an adverse reaction to penicillin if there was no history of allergic reactions. Choice D is also incorrect as a documented allergy to sulfa drugs does not directly increase the risk of an adverse reaction to penicillin.

4. A client with multiple sclerosis is admitted with an acute exacerbation. What is the nurse's priority action?

• A. Monitor the client’s vital signs every hour.
• B. Assess for changes in the client’s muscle strength.
• C. Administer prescribed corticosteroids to reduce inflammation.
• D. Educate the client on managing fatigue and preventing relapses.

Correct answer: C

Rationale: The correct answer is C. Administering prescribed corticosteroids to reduce inflammation is the priority action when a client with multiple sclerosis is admitted with an acute exacerbation. Corticosteroids help manage symptoms during exacerbations and reduce inflammation. Monitoring vital signs and assessing muscle strength are important aspects of care but not the priority during an acute exacerbation. Educating the client on managing fatigue and preventing relapses is essential but can be addressed after the acute exacerbation has been managed.

5. A young woman with multiple sclerosis just received several immunizations in preparation for moving into a college dormitory. Two days later, she reports to the nurse that she is experiencing increasing fatigue and visual problems. What teaching should the nurse provide?

• A. Immunizations can trigger a relapse of the disease, so get plenty of extra rest
• B. Visual problems are unrelated to the recent immunizations
• C. Increase fluid intake to reduce symptoms of fatigue
• D. Consult the healthcare provider immediately for steroid therapy

Correct answer: A

Rationale: Immunizations can sometimes trigger relapses in multiple sclerosis due to the activation of the immune system. Extra rest can help manage these symptoms. Choice B is incorrect because visual problems can be associated with the immune response triggered by immunizations in individuals with multiple sclerosis. While increasing fluid intake is generally good advice, in this case, the nurse should focus on explaining the possible connection between the immunizations and the symptoms experienced. Choice D is not the immediate course of action; educating the patient on the potential link between immunizations and symptom exacerbation is more appropriate at this stage.
