Nursing Elites

1. The healthcare provider prescribes 15 mg/kg of Streptomycin for an infant weighing 4 pounds. The drug is diluted in 25 ml of D5W to run over 8 hours. How much Streptomycin will the infant receive?

• A. 9 mg
• B. 18 mg
• C. 27 mg
• D. 36 mg

Correct answer: A

Rationale: To calculate the dosage, first, convert the weight from pounds to kg (4 lbs / 2.2 ≈ 1.82 kg). Then, multiply by the prescribed mg/kg (15 mg/kg * 1.82 kg ≈ 27.3 mg). However, since the question asks for the closest correct option, the infant will receive approximately 9 mg.

2. A patient with chronic pain is prescribed a fentanyl patch. What is the most important instruction for the nurse to provide?

• A. Apply the patch to a different site each time.
• B. Change the patch every 72 hours.
• C. Avoid using additional heating pads over the patch.
• D. Remove the patch before showering.

Correct answer: B

Rationale: The most important instruction for the nurse to provide to a patient prescribed a fentanyl patch is to change the patch every 72 hours. This ensures consistent pain control and prevents complications. It is crucial to rotate the application sites to prevent skin irritation or reactions. Using additional heating pads over the patch should be avoided as it can increase the absorption of the medication, leading to overdose or adverse effects. Removing the patch before showering is not necessary as long as the patch is securely in place.

3. In a patient with a history of chronic iron deficiency anemia requiring a recent blood transfusion and an extensive GI work-up, which statement is true based on their medications?

• A. A dedicated small bowel series has a high likelihood of being positive
• B. 81 mg of aspirin per day decreases the benefit of using a COX II inhibitor
• C. The patient should have a provocative arteriogram with heparin infusion to identify the source of blood loss
• D. Hormonal therapy has been shown to be effective in decreasing blood loss due to arteriovenous malformations

Correct answer: B

Rationale: The correct answer is B. Taking even a low dose of aspirin per day, such as 81 mg, can reduce the protective effect on the gastrointestinal mucosa that is gained from using a COX II selective inhibitor. Aspirin can increase the risk of gastrointestinal bleeding, which can counteract the benefits of COX II inhibitors in protecting the stomach lining.

4. A patient with rheumatoid arthritis is prescribed methotrexate. What should the nurse include in the patient teaching?

• A. Take folic acid supplements as prescribed.
• B. Avoid alcohol completely.
• C. Expect to see immediate results.
• D. Limit fluid intake to 1 liter per day.

Correct answer: A

Rationale: Patients prescribed methotrexate should be advised to take folic acid supplements as prescribed. Methotrexate can deplete folic acid levels, leading to side effects. By taking folic acid supplements as directed, the patient can reduce the risk of experiencing adverse effects associated with methotrexate therapy. It is important to note that the effects of methotrexate may not be immediate, so realistic expectations should be set with the patient. Alcohol should be avoided while taking methotrexate due to potential interactions and increased risk of liver toxicity. There is no specific recommendation to limit fluid intake to 1 liter per day in relation to methotrexate therapy.

5. A client with liver cirrhosis is prescribed lactulose. What is the purpose of this medication?

• A. To lower blood sugar levels
• B. To reduce ammonia levels
• C. To treat liver inflammation
• D. To improve bile flow

Correct answer: B

Rationale: Lactulose is prescribed to reduce ammonia levels in clients with liver cirrhosis. Elevated ammonia levels can lead to hepatic encephalopathy, a serious complication of liver cirrhosis. Lactulose works by acidifying the colon, which in turn traps ammonia in the colon and helps its elimination from the body through stool, thereby reducing the risk of hepatic encephalopathy. Choice A is incorrect because lactulose does not lower blood sugar levels. Choice C is incorrect as lactulose is not used to treat liver inflammation. Choice D is incorrect as lactulose does not improve bile flow.
