Nursing Elites

1. A patient in metabolic alkalosis is admitted to the emergency department, and pulse oximetry indicates that the O2 saturation is 94%. Which action should the nurse take next?

• A. Administer bicarbonate.
• B. Complete a head-to-toe assessment.
• C. Place the patient on high-flow oxygen.
• D. Obtain repeat arterial blood gases (ABGs).

Correct answer: C

Rationale: In a patient with metabolic alkalosis and an O2 saturation of 94%, placing the patient on high-flow oxygen is the correct action. Even though the O2 saturation seems adequate, metabolic alkalosis causes a left shift in the oxyhemoglobin dissociation curve, reducing oxygen delivery to tissues. Therefore, providing high-flow oxygen can help compensate for this. Administering bicarbonate would exacerbate the alkalosis. While completing a head-to-toe assessment and obtaining repeat ABGs are important interventions, the priority in this scenario is to improve oxygen delivery by placing the patient on high-flow oxygen.

2. The nurse is caring for a 10-year-old on admission to the burn unit. One assessment parameter that will indicate that the child has adequate fluid replacement is:

• A. Urinary output of 30 ml per hour
• B. No complaints of thirst
• C. Increased hematocrit
• D. Good skin turgor around burn

Correct answer: A

Rationale: For a child of this age, this is adequate output, yet does not suggest overload. Disruption of sodium-ATPase activity presumably causes an intracellular sodium shift which contributes to hypovolemia and cellular edema. Heat injury also initiates the release of inflammatory and vasoactive mediators. These mediators are responsible for local vasoconstriction, systemic vasodilation, and increased transcapillary permeability. Increase in transcapillary permeability results in a rapid transfer of water, inorganic solutes, and plasma proteins between the intravascular and interstitial spaces.

3. What is the primary nursing concern when caring for patients being treated with splints, casts, or traction?

• A. To assess for and prevent neurovascular complications or dysfunction
• B. To ensure adequate nutrition during the healing process
• C. To provide patient education for maintenance of splints, casts, or traction in the community
• D. To treat acute pain

Correct answer: A

Rationale: The primary nursing concern when caring for patients with splints, casts, or traction is to assess for and prevent neurovascular complications or dysfunction. This is crucial to ensure adequate circulation and nerve function, preventing long-term complications such as ischemia or nerve damage. While adequate nutrition and patient education are important aspects of care, they are not the primary concern in this scenario. Acute pain management is important but is secondary to preventing neurovascular complications in patients treated with splints, casts, or traction.

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 nurse prepares to care for a 4-year-old newly admitted for rhabdomyosarcoma. The nurse should alert the staff to pay more attention to the function of which area of the body?

• A. All striated muscles
• B. The cerebellum
• C. The kidneys
• D. The leg bones

Correct answer: A

Rationale: Rhabdomyosarcoma is the most common soft tissue sarcoma in children, originating in striated (skeletal) muscles and potentially affecting any part of the body. Symptoms vary based on the location of the tumor. In the head or neck area, symptoms may include sudden bulging or swelling of the eyes, conjunctival chemosis, and headache. Rhabdomyosarcoma can also impact organs like the urinary or reproductive system. Common metastatic sites include the lungs. Therefore, the nurse should pay attention to the function of all striated muscles in the child to monitor for any signs or symptoms related to the disease. Choices B, C, and D are incorrect as rhabdomyosarcoma primarily involves striated muscles and does not specifically target the cerebellum, kidneys, or leg bones.
