Nursing Elites

1. A nurse is reviewing a client's medication regimen. Which of the following medications places the client at increased risk for digoxin toxicity?

• A. Calcium channel blockers
• B. Potassium-sparing diuretics
• C. Beta blockers
• D. Loop diuretics

Correct answer: D

Rationale: The correct answer is D, Loop diuretics. Loop diuretics can lead to hypokalemia, which increases the risk for digoxin toxicity. Loop diuretics cause potassium loss, and hypokalemia can potentiate the toxic effects of digoxin. Choices A, B, and C are incorrect because calcium channel blockers, potassium-sparing diuretics, and beta blockers do not directly increase the risk of digoxin toxicity.

2. A client with an artificial heart valve is prescribed warfarin therapy. Which of the following laboratory values should the nurse monitor to assess the therapeutic effect of warfarin?

• A. Hemoglobin (Hgb)
• B. Prothrombin time (PT)
• C. Bleeding time
• D. Activated partial thromboplastin time (aPTT)

Correct answer: B

Rationale: The correct answer is B: Prothrombin time (PT). Warfarin is an anticoagulant medication that works by inhibiting the clotting factors dependent on vitamin K, such as factors II, VII, IX, and X. The prothrombin time (PT) measures the extrinsic pathway and is used to monitor the therapeutic effects of warfarin therapy. Monitoring PT helps assess the time it takes for the blood to clot, ensuring that the anticoagulant effect is within the desired range. Choices A, C, and D are incorrect because hemoglobin (Hgb) measures the amount of hemoglobin in the blood, bleeding time assesses the time it takes for bleeding to stop, and activated partial thromboplastin time (aPTT) is used to monitor heparin therapy, not warfarin therapy.

3. Before administering blood products, which action should be taken?

• A. Assess the client's temperature
• B. Document client response
• C. Prime IV tubing with 0.45% sodium chloride
• D. Administer epinephrine

Correct answer: A

Rationale: Correct answer: Before administering blood products, the client's temperature must be assessed to establish a baseline and monitor for transfusion reactions. Choice B is incorrect because documenting client response should occur after administering the blood products. Choice C is incorrect as priming IV tubing with 0.45% sodium chloride is not directly related to assessing the client before administering blood products. Choice D is incorrect because administering epinephrine is not a routine action before administering blood products.

4. A nurse is caring for a client prescribed montelukast. Which of the following should the nurse include in teaching related to this medication?

• A. Advise the client to take the medication once daily at bedtime
• B. This medication is for the acute management of asthma
• C. Avoid dairy products while taking this medication
• D. If the client forgets to take the medication for a few days, he should not double up on doses to catch up

Correct answer: A

Rationale: The correct answer is to advise the client to take montelukast once daily at bedtime to maintain therapeutic effects. Choice B is incorrect because montelukast is not typically used for acute asthma management but for chronic treatment. Choice C is incorrect as there are no known interactions between montelukast and dairy products. Choice D is incorrect as it is not safe to double up on doses if the client forgets to take the medication; the missed dose should be skipped and the regular dosing schedule maintained.

5. A nurse is administering metformin to a client with type 2 diabetes. Which of the following adverse effects should the nurse monitor for in this client?

• A. Diarrhea
• B. Hyperglycemia
• C. Hypoglycemia
• D. Lactic acidosis

Correct answer: D

Rationale: The correct answer is D, Lactic acidosis. Lactic acidosis is a rare but serious adverse effect of metformin use. Metformin is not known to cause hyperglycemia or hypoglycemia. Diarrhea is a common gastrointestinal side effect of metformin but is not as serious as lactic acidosis, which requires immediate medical attention.
