Nursing Elites

1. Which of the following is the primary site of activity for the drug Warfarin?

• A. Kidney
• B. Liver
• C. Blood
• D. Heart

Correct answer: B

Rationale: Warfarin primarily affects the liver where it inhibits the synthesis of clotting factors.

2. A client with chronic renal disease is receiving therapy with epoetin alfa. Which of the following laboratory results should the nurse review for an indication of a therapeutic effect of the medication?

• A. The leukocyte count
• B. The platelet count
• C. The hematocrit (Hct)
• D. The erythrocyte sedimentation rate (ESR)

Correct answer: C

Rationale: The correct answer is C: The hematocrit (Hct). Monitoring the hematocrit is essential to assess the therapeutic effect of epoetin alfa because this medication stimulates red blood cell production in clients with chronic renal disease. The leukocyte count (choice A) and platelet count (choice B) are not directly affected by epoetin alfa therapy. The erythrocyte sedimentation rate (ESR) (choice D) is a non-specific marker of inflammation and is not used to monitor the therapeutic effect of epoetin alfa.

3. A healthcare provider is reviewing the health history of a client who is starting therapy with tamoxifen. The healthcare provider should recognize that tamoxifen is contraindicated in which of the following clients?

• A. A client with a history of deep-vein thrombosis
• B. A client with a history of migraine headaches
• C. A client with a history of hypertension
• D. A client with a history of anemia

Correct answer: A

Rationale: Tamoxifen is contraindicated in clients with a history of thromboembolic events, such as deep-vein thrombosis, due to the increased risk of blood clots forming and leading to serious complications like pulmonary embolism. Clients with a history of deep-vein thrombosis are at a higher risk of recurrent thromboembolic events when taking tamoxifen, making it unsafe for such individuals. Choices B, C, and D are not contraindications for tamoxifen therapy, as migraine headaches, hypertension, and anemia do not directly interact with tamoxifen's mechanism of action or pose significant risks when used together.

4. Which of the following conditions is not treated with epinephrine?

• A. Renal disease
• B. Asthma
• C. Hypotension
• D. Glaucoma

Correct answer: A

Rationale: Epinephrine is not used to treat renal disease. Epinephrine is commonly used to treat conditions like asthma, hypotension, and glaucoma, but it is not an appropriate treatment for renal disease. Renal disease requires specific management strategies that do not involve the use of epinephrine.

5. When a client reports urticaria and dyspnea after receiving amoxicillin/clavulanic acid, which medication should be administered first?

• A. Administer epinephrine
• B. Administer albuterol
• C. Administer diphenhydramine
• D. Administer prednisone

Correct answer: A

Rationale: In the scenario described, the client is experiencing symptoms of a severe allergic reaction. The priority intervention is to administer epinephrine. Epinephrine acts quickly to reverse the effects of the allergic reaction and can be life-saving in cases of anaphylaxis. Albuterol is used for bronchodilation and may help with respiratory symptoms but is not the first-line treatment for anaphylaxis. Diphenhydramine and prednisone are used for allergic reactions but are not as rapid-acting as epinephrine and should be considered after administering epinephrine in this situation.
