Nursing Elites

1. A 3-year-old had a hip spica cast applied 2 hours ago. In order to facilitate drying, the nurse should:

• A. Expose the cast to air and turn the child frequently.
• B. Use a heat lamp to reduce the drying time.
• C. Handle the cast with the abductor bar.
• D. Turn the child as little as possible.

Correct answer: A

Rationale: After a hip spica cast is applied, it is important to facilitate drying by exposing the cast to air and turning the child frequently, approximately every 2 hours. This helps ensure even drying and prevents skin breakdown. Using a heat lamp can cause burns and should be avoided. Handling the cast with the abductor bar is not necessary for the drying process and may cause discomfort to the child. Turning the child as little as possible is not recommended as regular turning helps prevent complications like pressure ulcers and stiffness.

2. The laboratory has just called with the arterial blood gas (ABG) results on four patients. Which result is most important for the nurse to report immediately to the health care provider?

• A. pH 7.34, PaO2 82 mm Hg, PaCO2 40 mm Hg, and O2 sat 97%
• B. pH 7.35, PaO2 85 mm Hg, PaCO2 45 mm Hg, and O2 sat 95%
• C. pH 7.46, PaO2 90 mm Hg, PaCO2 32 mm Hg, and O2 sat 98%
• D. pH 7.31, PaO2 91 mm Hg, PaCO2 50 mm Hg, and O2 sat 96%

Correct answer: D

Rationale: The correct answer is D: pH 7.31, PaO2 91 mm Hg, PaCO2 50 mm Hg, and O2 sat 96%. These ABG results indicate uncompensated respiratory acidosis, a critical condition that requires immediate attention. In respiratory acidosis, there is an excess of carbon dioxide in the blood, leading to a decrease in pH. The other options present normal or near-normal ABG values, indicating adequate oxygenation and ventilation. Therefore, these values would not be as urgent to report compared to the patient with respiratory acidosis in option D.

3. The patient with idiopathic pulmonary arterial hypertension (IPAH) is receiving epoprostenol (Flolan). Which assessment information requires the most immediate action by the nurse?

• A. The oxygen saturation is 94%.
• B. The blood pressure is 98/56 mm Hg.
• C. The patient's central IV line is disconnected.
• D. The international normalized ratio (INR) is prolonged.

Correct answer: C

Rationale: The most immediate action required by the nurse is to address the disconnected central IV line delivering epoprostenol (Flolan). Epoprostenol has a short half-life of 6 minutes, necessitating immediate reconnection to prevent rapid clinical deterioration. While oxygen saturation, blood pressure, and INR are important parameters requiring monitoring and intervention, the priority lies in ensuring the continuous delivery of the critical medication to stabilize the patient's condition.

4. Claudication is a well-known effect of peripheral vascular disease. Which of the following facts about claudication is correct? Select the one that doesn't apply:

• A. It results when oxygen demand is greater than oxygen supply.
• B. It is characterized by pain that often occurs during rest.
• C. It is a result of tissue hypoxia.
• D. It is characterized by cramping and weakness.

Correct answer: D

Rationale: Claudication is a symptom of peripheral vascular disease where there is an inadequate supply of oxygen to the muscles due to reduced blood flow. This mismatch between oxygen demand and supply leads to tissue hypoxia, resulting in cramping, weakness, and discomfort. Option D correctly states that claudication is characterized by cramping and weakness, making it the correct answer. Options A, B, and C are incorrect. Claudication occurs when oxygen demand exceeds supply, not the other way around as stated in Option A. Pain in claudication typically occurs with activity, not at rest as mentioned in Option B. While tissue hypoxia is a consequence of claudication, it is not the primary cause, making Option C incorrect.

5. A newborn is having difficulty maintaining a temperature above 98 degrees Fahrenheit and has been placed in a warming isolette. Which action is a nursing priority?

• A. Protect the neonate's eyes from the heat lamp
• B. Monitor the neonate's temperature
• C. Warm all medications and liquids before administration
• D. Avoid touching the neonate with cold hands

Correct answer: B

Rationale: When a newborn is placed in a warming isolette due to difficulty maintaining temperature, the priority action is to continuously monitor the neonate's temperature to prevent overheating. Using heat lamps is unsafe as their temperature cannot be regulated, potentially causing harm. Warming medications and fluids before administration is not necessary in this situation. While touching the neonate with cold hands may startle them, it does not pose a safety risk compared to monitoring and controlling the temperature.
