Nursing Elites

1. When obtaining a rectal temperature with an electronic thermometer, which action is most important for the nurse to perform?

• A. Hold the thermometer in place.
• B. Place the disposable pad under the buttocks.
• C. Instruct the client to breathe deeply.
• D. Return the probe to the charger.

Correct answer: A

Rationale: When obtaining a rectal temperature with an electronic thermometer, holding the thermometer in place is crucial. This action ensures accurate temperature measurement and prevents injury to the client. Option B, placing a disposable pad under the buttocks, is not the most important action; it may enhance comfort but does not impact the accuracy of the temperature reading. Option C, instructing the client to breathe deeply, is irrelevant to obtaining a rectal temperature. Option D, returning the probe to the charger, is an incorrect action after temperature measurement.

2. A client with a history of atrial fibrillation is prescribed warfarin (Coumadin). Which laboratory value is most concerning?

• A. INR of 3.0
• B. Prothrombin time (PT) of 15 seconds
• C. Hemoglobin of 10 g/dl
• D. White blood cell count

Correct answer: A

Rationale: An INR of 3.0 is most concerning in a client prescribed warfarin (Coumadin) as it indicates a high risk of bleeding, requiring immediate intervention. A high INR value suggests that the blood is taking longer to clot, putting the patient at an increased risk of hemorrhage. Prothrombin time (PT) measures how long it takes for blood to clot, but the specific value of 15 seconds is within the normal range. Hemoglobin of 10 g/dl indicates mild anemia and does not directly relate to the risk of bleeding associated with warfarin therapy. White blood cell count assesses immune function and infection risk, but it is not directly related to the anticoagulant effects of warfarin.

3. Following routine diagnostic tests, a client who is symptom-free is diagnosed with Paget's disease. Client teaching should be directed toward what important goal for this client?

• A. Maintain adequate cardiac output.
• B. Promote adequate tissue perfusion.
• C. Promote rest and sleep.
• D. Reduce the risk for injury.

Correct answer: D

Rationale: In Paget's disease, bone remodeling is affected, leading to increased risk for fractures. Therefore, the primary goal of client teaching should focus on reducing the risk for injury. Choices A and B are not directly related to the primary concern of Paget's disease, which is bone fractures. Choice C, promoting rest and sleep, is important for overall health but is not the priority when considering the specific risks associated with Paget's disease.

4. When planning care for a 10-year-old child with pneumonia receiving oxygen at 5l/min per nasal cannula, what principle of oxygen administration should the nurse consider?

• A. Avoid administration of oxygen at high levels for extended periods.
• B. Increase oxygen flow rate if the child is still tachypneic.
• C. Reduce oxygen levels gradually after symptoms improve.
• D. Humidify the oxygen to prevent drying of mucous membranes.

Correct answer: A

Rationale: The correct principle of oxygen administration to consider is to avoid administering oxygen at high levels for extended periods. High levels of oxygen for prolonged periods can lead to oxygen toxicity, especially in pediatric patients. Increasing the oxygen flow rate based on tachypnea may not be necessary and can potentially lead to oxygen toxicity. Gradually reducing oxygen levels after symptoms improve may compromise the child's oxygenation. While humidifying oxygen is important to prevent drying of mucous membranes, the primary concern in this case is to avoid high oxygen levels for an extended duration to prevent oxygen toxicity.

5. A 12-year-old boy has a body mass index (BMI) of 28, a systolic pressure, and a glycosylated hemoglobin (HBA1C) of 7.8%. Which selection indicates that his mother understands the management of his diet?

• A. One whole-wheat bagel with cream cheese, two strips of bacon, six ounces of orange juice.
• B. Two eggs with toast and butter, 8 ounces of milk.
• C. Fresh fruit salad with low-fat yogurt.
• D. Pancakes with syrup and sausage links.

Correct answer: C

Rationale: The correct answer is C. Fresh fruit salad with low-fat yogurt is a healthier choice for managing the diet of a 12-year-old boy with a high BMI and elevated HBA1C. This choice provides a good balance of nutrients, fiber, and low-fat content, helping to lower BMI and maintain healthy blood sugar levels. Choices A, B, and D are less ideal as they contain higher levels of refined carbohydrates, saturated fats, and sugars, which can contribute to weight gain and worsen blood sugar control in this scenario.
