Nursing Elites

1. While teaching a group of adults about health promotion activities, a nurse identifies a behavior that poses the most significant risk factor for the development of skin cancer. Which behavior should the nurse address?

• A. Consuming a high-fat diet
• B. Using tanning beds
• C. Smoking cigarettes
• D. Drinking alcohol

Correct answer: B

Rationale: Using tanning beds is the most significant risk factor for developing skin cancer. Ultraviolet (UV) radiation from tanning beds damages the skin and increases the risk of skin cancer. Consuming a high-fat diet, smoking cigarettes, and drinking alcohol are unhealthy behaviors but are not directly linked to the development of skin cancer like UV exposure from tanning beds.

2. A client who is bleeding after a vaginal delivery receives a prescription for methylergonovine (Methergine) 0.4 mg IM every 2 hours, not to exceed 5 doses. The medication is available in ampules containing 0.2 mg/ml. What is the maximum dosage in mg that the nurse should administer to this client?

• A. Encourage oral fluids as tolerated
• B. Decrease oral intake to 200 ml
• C. Allow the client to have exactly 400 ml oral intake
• D. Limit oral intake to 900 to 1,000 ml

Correct answer: D

Rationale: The maximum dosage the nurse should administer is 2 mg. This is calculated based on the prescription of 0.4 mg IM every 2 hours, not to exceed 5 doses. Since the medication is available in ampules containing 0.2 mg/ml, the nurse should administer 2 ml (0.2 mg/ml x 10 ml) for each dose, not exceeding 5 doses. Therefore, the nurse should limit the client's oral intake to 900 to 1,000 ml, to avoid exceeding the maximum dosage of 2 mg.

3. A client in acute renal failure has a serum potassium of 7.5 mEq/L. Based on this finding, the nurse should anticipate implementing which action?

• A. Administer an IV of normal saline rapidly and NPH insulin subcutaneously.
• B. Administer a retention enema of Kayexalate.
• C. Add 40 mEq of KCL (potassium chloride) to the present IV solution.
• D. Administer a lidocaine bolus IV push.

Correct answer: B

Rationale: In acute renal failure with a high serum potassium level, the priority intervention is to lower potassium levels to prevent complications like cardiac arrhythmias. Administering a retention enema of Kayexalate is the correct action as it helps lower high potassium levels by exchanging sodium for potassium in the intestines. Options A, C, and D are incorrect. Administering normal saline rapidly and NPH insulin or adding more potassium to the IV solution can further increase potassium levels, worsening the condition. Lidocaine is not indicated for treating hyperkalemia.

4. A client diagnosed with a deep vein thrombus (DVT) followed by a diagnosis of pulmonary embolism (PE) is receiving heparin via an infusion pump at a rate of 1400 u/hour. The client tells the nurse, 'I wish this medicine would hurry up and dissolve this clot in my lung so that I can go home'. What response is best for the nurse to provide?

• A. Heparin prevents future clot formation, but your risk of bleeding needs to be monitored closely
• B. You seem to be concerned about the length of time it takes for Heparin to dissolve this clot
• C. Let me contact your surgeon and find out if Heparin IV therapy can be administered to you at home
• D. Why are you so anxious to leave the hospital when you know you are not well enough yet?

Correct answer: A

Rationale: Choice A is the best response because it educates the client about the role of heparin in preventing future clot formation rather than dissolving the existing clot. This helps the client understand the medication's function and the importance of closely monitoring for signs of bleeding, a common side effect of heparin therapy. Choice B acknowledges the client's concern but does not provide accurate information about heparin's mechanism of action. Choice C is premature as it suggests transitioning to home therapy without addressing the client's concerns or explaining heparin's purpose. Choice D does not address the client's statement and instead questions their desire to leave the hospital.

5. The nurse is assessing a client who has a prescription for digoxin (Lanoxin). Which finding indicates that the client is at risk for digoxin toxicity?

• A. Heart rate of 60 beats per minute
• B. Blood pressure of 120/80 mm Hg
• C. Respiratory rate of 18 breaths per minute
• D. Serum potassium level of 3.0 mEq/L

Correct answer: D

Rationale: A low serum potassium level increases the risk of digoxin toxicity. Digoxin toxicity is more likely to occur in individuals with low potassium levels because potassium is crucial for proper heart function. A heart rate of 60 beats per minute, blood pressure of 120/80 mm Hg, and respiratory rate of 18 breaths per minute are within normal ranges and do not directly indicate an increased risk of digoxin toxicity.
