Nursing Elites

1. A nurse is caring for a client who has a prescription for warfarin. Which of the following laboratory values should the nurse monitor?

• A. Prothrombin time (PT)
• B. Hemoglobin
• C. aPTT
• D. INR

Correct answer: D

Rationale: The correct answer is D, INR. The International Normalized Ratio (INR) is used to monitor the therapeutic effect of warfarin and to adjust the dose as needed. While Prothrombin time (PT) and activated Partial Thromboplastin Time (aPTT) are also related to coagulation studies, monitoring INR specifically helps in managing warfarin therapy. Hemoglobin, on the other hand, is not typically monitored in relation to warfarin therapy.

2. A healthcare professional is preparing to administer ceftriaxone IM to a client. Which of the following actions should the healthcare professional take?

• A. Administer the medication using a tuberculin syringe
• B. Administer the medication at a 45-degree angle
• C. Use the dorsogluteal muscle for injection
• D. Aspirate for blood return before injecting the medication

Correct answer: D

Rationale: Correct Answer: When administering intramuscular injections like ceftriaxone, it is essential to aspirate for blood return before injecting the medication to ensure that the needle is not in a blood vessel. Choices A and B are incorrect because ceftriaxone is typically administered using a syringe appropriate for IM injections (not a tuberculin syringe) and injected at a 90-degree angle rather than 45 degrees. Choice C is incorrect because the dorsogluteal site is no longer recommended for IM injections due to potential injury to the sciatic nerve and other structures.

3. A nurse is caring for a client who is receiving continuous cardiac monitoring. The client's heart rate is 69/min, and the PR interval is 0.24 seconds. What cardiac rhythm should the nurse interpret this finding as?

• A. First-degree AV block.
• B. Premature ventricular contraction.
• C. Sinus bradycardia.
• D. Atrial fibrillation.

Correct answer: A

Rationale: The correct answer is A: First-degree AV block. A PR interval of 0.24 seconds indicates a prolonged PR interval, which is characteristic of first-degree AV block. This rhythm is considered benign and often does not require treatment. Choice B, premature ventricular contraction, is characterized by early, abnormal ventricular contractions and would not be indicated by the findings provided. Choice C, sinus bradycardia, would present with a normal PR interval but a heart rate less than 60 beats per minute. Choice D, atrial fibrillation, is characterized by an irregularly irregular rhythm with no identifiable P waves, which does not align with the findings of a prolonged PR interval in this scenario.

4. A nurse is reviewing the laboratory results of a client who has rheumatoid arthritis and is prescribed methotrexate. Which of the following results should the nurse report to the provider?

• A. White blood cell count 8,000/mm3
• B. Platelet count 150,000/mm3
• C. Hemoglobin 14 g/dL
• D. Aspartate aminotransferase (AST) 60 units/L

Correct answer: D

Rationale: The correct answer is D: Aspartate aminotransferase (AST) 60 units/L. An elevated AST level indicates liver damage, a side effect of methotrexate, and should be reported. Choices A, B, and C are within normal ranges and do not indicate potential complications related to methotrexate therapy.

5. A patient is receiving radiation therapy. Which of the following skin care instructions should the nurse provide?

• A. Apply a heating pad to the radiation site.
• B. Use scented lotions to moisturize the skin.
• C. Keep the radiation site covered with a bandage.
• D. Wear loose clothing over the radiation site.

Correct answer: D

Rationale: Correct Answer: The nurse should instruct the patient to wear loose clothing over the radiation site. This helps prevent skin irritation and promotes healing by reducing friction and irritation on the treated area.\nChoice A is incorrect because applying a heating pad can further irritate the skin that is already sensitive due to radiation therapy.\nChoice B is incorrect because scented lotions may contain ingredients that could further irritate the skin.\nChoice C is incorrect because covering the radiation site with a bandage can trap moisture and lead to skin breakdown, increasing the risk of infection.
