Nursing Elites

1. Which lab value is essential for a patient receiving warfarin therapy?

• A. Monitor INR
• B. Monitor sodium levels
• C. Monitor potassium levels
• D. Monitor platelet count

Correct answer: A

Rationale: The correct answer is to monitor the INR (International Normalized Ratio) for a patient receiving warfarin therapy. INR monitoring is crucial to assess the effectiveness of warfarin in preventing blood clots while minimizing the risk of bleeding. Monitoring sodium levels (choice B), potassium levels (choice C), or platelet count (choice D) is not specifically essential for patients on warfarin therapy and does not provide direct information on the drug's anticoagulant effects.

2. A nurse is caring for a client who is receiving radiation therapy. Which of the following findings should the nurse expect?

• A. Weight gain
• B. Mouth sores
• C. Hyperpigmentation
• D. Increased saliva production

Correct answer: B

Rationale: The correct answer is B: Mouth sores. Mouth sores are a common side effect of radiation therapy, especially when the treatment is focused on the head or neck area. Weight gain is not typically associated with radiation therapy; instead, clients may experience weight loss due to side effects like nausea and loss of appetite. Hyperpigmentation is not a common finding related to radiation therapy. Increased saliva production is not a typical side effect of radiation therapy; instead, clients may experience dry mouth.

3. A nurse is preparing to apply a transdermal nicotine patch for a client. Which of the following actions should the nurse take?

• A. Shave hairy areas of skin prior to application.
• B. Wear gloves to apply the patch to the client's skin.
• C. Apply the patch within 1 hr of removing it from the protective pouch.
• D. Remove the previous patch and place it in a tissue.

Correct answer: B

Rationale: The correct answer is to wear gloves to apply the patch to the client's skin. This action ensures that the nurse does not absorb any medication through their own skin, promoting safety. Choice A is incorrect because shaving is not necessary and could irritate the skin. Choice C is incorrect because transdermal patches should be applied immediately after removal from the protective pouch to maintain their efficacy. Choice D is incorrect because used patches should be folded and discarded safely according to facility protocols.

4. Which lab value is critical for monitoring warfarin therapy?

• A. Monitor INR
• B. Monitor platelet count
• C. Monitor sodium levels
• D. Monitor calcium levels

Correct answer: A

Rationale: The correct answer is A: Monitor INR. INR (International Normalized Ratio) is crucial for monitoring warfarin therapy as it helps assess the therapeutic effectiveness and bleeding risks associated with the medication. INR measures the clotting tendency of blood, which is essential in determining the appropriate dosage of warfarin. Monitoring platelet count (B), sodium levels (C), or calcium levels (D) is not primarily used for assessing warfarin therapy. Platelet count is more relevant in assessing bleeding disorders, while sodium and calcium levels are typically monitored for different medical conditions unrelated to warfarin therapy.

5. A client with a new diagnosis of hypertension is being taught by a nurse. Which of the following statements by the client indicates an understanding of the teaching?

• A. I should avoid eating foods high in potassium.
• B. I will check my blood pressure at least once a week.
• C. I should increase my intake of dairy products.
• D. I should exercise for 30 minutes at least 5 days a week.

Correct answer: D

Rationale: The correct answer is D. Exercising for 30 minutes at least 5 days a week helps manage hypertension by promoting cardiovascular health. Statements A, B, and C are incorrect. Avoiding foods high in potassium is not necessary unless specifically advised by a healthcare provider. Checking blood pressure once a week is not frequent enough for effective monitoring. Increasing dairy product intake is not a recommended approach to managing hypertension.
