Nursing Elites

1. To detect possible complications in a patient with severe cirrhosis who has bleeding esophageal varices, it is most important for the nurse to monitor

• A. bilirubin levels.
• B. ammonia levels.
• C. potassium levels.
• D. prothrombin time.

Correct answer: B

Rationale: In a patient with severe cirrhosis and bleeding esophageal varices, monitoring ammonia levels is crucial. Severe liver dysfunction impairs the metabolism of protein in the GI tract, leading to increased ammonia levels. Elevated ammonia levels can result in hepatic encephalopathy, a serious complication. Monitoring bilirubin levels is important for assessing liver function and jaundice but may not directly reflect the risk of complications from bleeding esophageal varices. Potassium levels are important but not the most critical in this scenario. Prothrombin time is essential for evaluating coagulation status but does not directly relate to the risk of complications from bleeding esophageal varices in this patient.

2. When administering a-interferon and ribavirin (Rebetol) to a patient with chronic hepatitis C, the nurse should monitor for which complication?

• A. Leukopenia.
• B. Hypokalemia.
• C. Polycythemia.
• D. Hypoglycemia.

Correct answer: B

Rationale: When administering a-interferon and ribavirin (Rebetol) for chronic hepatitis C, the nurse should monitor for hypokalemia. This combination therapy is known to cause leukopenia, not polycythemia or hypoglycemia. Hypokalemia is a common electrolyte imbalance that can occur with these medications, making it the correct answer to monitor for in this case.

3. Why should a 30-year-old Caucasian woman who works the night shift take Vitamin D supplements?

• A. It's a standard part of the overall nutritional treatment for the prevention of osteomalacia.
• B. It helps your intestines absorb calcium, which is important for bone formation.
• C. It stimulates skin cells to produce calcium, which is then released into the bloodstream to be used for bone formation.
• D. Vitamin D supplements should not be taken by someone of your age.

Correct answer: B

Rationale: The correct answer is B: 'It helps your intestines absorb calcium, which is important for bone formation.' Vitamin D plays a crucial role in aiding the absorption of calcium from the intestines into the bloodstream, which is essential for bone health and formation. Choice A is incorrect because it does not specifically address the role of Vitamin D in calcium absorption. Choice C is incorrect as Vitamin D does not stimulate skin cells to produce calcium; rather, it helps regulate calcium levels in the body. Choice D is incorrect as age alone is not a contraindication for Vitamin D supplementation; the need for supplementation is based on individual health status and risk factors.

4. A child weighing 30 kg arrives at the clinic with diffuse itching as the result of an allergic reaction to an insect bite. Diphenhydramine (Benadryl) 25 mg 3 times a day is prescribed. The correct pediatric dose is 5 mg/kg/day. Which of the following best describes the prescribed drug dose?

• A. It is the correct dose
• B. The dose is too low
• C. The dose is too high
• D. The dose should be increased or decreased, depending on the symptoms

Correct answer: B

Rationale: The correct pediatric dose of diphenhydramine is 5 mg/kg/day. This child weighs 30 kg, so the calculated dose would be 5 mg/kg x 30 kg = 150 mg/day. Since the prescription is for 25 mg 3 times a day, the total daily dose is 25 mg x 3 = 75 mg/day, which is lower than the calculated dose of 150 mg/day. Therefore, the prescribed dose of 25 mg 3 times a day is too low for this child. The dose should be adjusted to meet the correct dosage of 150 mg/day, which would be 50 mg 3 times a day. It is important not to titrate the dosage based on symptoms without consulting a physician, as this can lead to inappropriate medication administration.

5. A patient in the emergency room has a fractured left elbow and presents with an unequal radial pulse, swelling, and numbness in the left hand after waiting for 5 hours. What is the nurse's priority intervention?

• A. Place the patient in a supine position
• B. Ask the patient to rate his pain on a scale of 1 to 10.
• C. Wrap the fractured area with a snug dressing
• D. Start an IV in the other arm.

Correct answer: D

Rationale: The correct answer is to start an IV in the other arm. In this scenario, the patient is showing signs of Acute Compartment Syndrome, a serious condition that occurs due to increased pressure within a muscle compartment, leading to decreased blood flow and potential tissue damage. Starting an IV is crucial as the patient may require emergency surgery, such as a fasciotomy, to relieve the pressure and prevent further complications. Placing the patient in a supine position, asking about pain levels, or wrapping the fractured area, though important, are not the priority interventions in this critical situation where immediate medical intervention is necessary to prevent irreversible damage or loss of limb.
