Nursing Elites

1. A client is receiving heparin therapy. Which of the following laboratory results indicates the client is receiving an effective dose of heparin?

• A. INR 1.5
• B. aPTT 60 seconds
• C. Platelets 150,000/mm³
• D. Potassium 4.0 mEq/L

Correct answer: B

Rationale: An aPTT of 60 seconds indicates the client is receiving an effective dose of heparin. The activated partial thromboplastin time (aPTT) measures the time it takes for a clot to form, and a therapeutic range for heparin therapy is usually 1.5 to 2 times the control value, which is around 60-80 seconds. An INR of 1.5 is not related to heparin therapy, as it is commonly used to monitor warfarin therapy. Platelet count and potassium levels are not direct indicators of the effectiveness of heparin therapy.

2. A nurse is planning care for a client who has a new prescription for a peripheral intravenous (IV) catheter. Which of the following actions should the nurse take to prevent infection?

• A. Shave the hair at the insertion site.
• B. Cleanse the site with povidone-iodine.
• C. Wear sterile gloves when changing the dressing.
• D. Change the IV site every 48 to 72 hours.

Correct answer: D

Rationale: The correct action to prevent infection when caring for a client with a new peripheral IV catheter is to change the IV site every 48 to 72 hours. Shaving the hair at the insertion site can actually increase the risk of infection by causing microabrasions in the skin. While cleansing the site with povidone-iodine is important before insertion, it is not necessary to continue doing so once the IV is in place. Wearing sterile gloves when changing the dressing is crucial for maintaining aseptic technique but does not directly prevent infection related to the IV site itself.

3. What is the priority intervention for a patient with suspected pulmonary embolism?

• A. Administer oxygen
• B. Administer anticoagulants
• C. Administer bronchodilators
• D. Reposition the patient

Correct answer: A

Rationale: Administering oxygen is the priority intervention for a patient with suspected pulmonary embolism. Maintaining adequate oxygenation is crucial in these patients to prevent hypoxemia and support oxygen delivery to tissues. Administering anticoagulants may be necessary but is not the initial priority. Administering bronchodilators is not indicated for pulmonary embolism. Repositioning the patient does not address the immediate need for oxygenation.

4. A healthcare professional is reviewing the laboratory results of a client who is receiving chemotherapy. Which of the following findings should the healthcare professional report immediately?

• A. White blood cell count of 4,500/mm³
• B. Hemoglobin level of 8 g/dL
• C. Platelet count of 90,000/mm³
• D. Serum potassium level of 3.5 mEq/L

Correct answer: C

Rationale: A platelet count of 90,000/mm³ indicates thrombocytopenia, which increases the risk of bleeding and requires immediate intervention. Thrombocytopenia can lead to serious bleeding complications, so it is crucial to address this finding promptly. A low white blood cell count (choice A) may indicate neutropenia but is not as immediately life-threatening as severe thrombocytopenia. A hemoglobin level of 8 g/dL (choice B) would require intervention but is not as urgent as addressing a critically low platelet count. A serum potassium level of 3.5 mEq/L (choice D) is on the lower side of normal but does not pose an immediate risk to the client's safety compared to severe thrombocytopenia.

5. A nurse is caring for a client who is receiving radiation therapy for breast cancer. Which of the following skin care instructions should the nurse provide?

• A. Wear loose clothing over the radiation site.
• B. Use scented lotions to moisturize the skin.
• C. Apply ice packs to the radiation site for pain relief.
• D. Expose the radiation site to sunlight for 20 minutes daily.

Correct answer: A

Rationale: The correct answer is A: Wear loose clothing over the radiation site. Clients receiving radiation therapy should wear loose clothing over the treatment area to prevent irritation and promote healing. Choice B is incorrect as scented lotions can irritate the skin during radiation therapy. Choice C is incorrect because ice packs should not be applied to the radiation site as they can exacerbate skin reactions. Choice D is incorrect as exposing the radiation site to sunlight can increase skin damage and should be avoided.
