Nursing Elites

1. How should the nurse interpret the following arterial blood gas results for a patient who had a tracheostomy placed after a motor vehicle crash: pH 7.48, PaO2 85 mm Hg, PaCO2 32 mm Hg, and HCO3 25 mEq/L?

• A. Metabolic acidosis
• B. Metabolic alkalosis
• C. Respiratory acidosis
• D. Respiratory alkalosis

Correct answer: D

Rationale: The patient's pH of 7.48 indicates alkalosis, and the low PaCO2 of 32 mm Hg suggests a respiratory cause. The HCO3 level is normal, ruling out metabolic causes. Therefore, the correct interpretation is respiratory alkalosis. Options A, B, and C are incorrect as they do not align with the pH and PaCO2 values provided.

2. The nurse is caring for a patient with a massive burn injury and possible hypovolemia. Which assessment data will be of most concern to the nurse?

• A. Blood pressure is 90/40 mm Hg.
• B. Urine output is 30 mL over the last hour.
• C. Oral fluid intake is 100 mL over the last 8 hours.
• D. There is prolonged skin tenting over the sternum.

Correct answer: A

Rationale: The correct answer is A: "Blood pressure is 90/40 mm Hg." A low blood pressure reading of 90/40 mm Hg indicates that the patient may be developing hypovolemic shock due to intravascular fluid loss from the burn injury. This finding is of utmost concern as it suggests systemic hypoperfusion, requiring immediate intervention to prevent complications. Choices B, C, and D also indicate signs of dehydration and the need to increase fluid intake; however, they are not as urgent as addressing the hypotension and potential shock presented in choice A.

3. When caring for a patient with renal failure on a low phosphate diet, the nurse will inform unlicensed assistive personnel (UAP) to remove which food from the patient’s food tray?

• A. Grape juice
• B. Milk carton
• C. Mixed green salad
• D. Fried chicken breast

Correct answer: B

Rationale: The correct answer is B: Milk carton. Foods high in phosphate, like milk and other dairy products, are restricted on low-phosphate diets to manage renal failure. Green, leafy vegetables, high-fat foods, and fruits/juices are not high in phosphate and are not restricted. Therefore, grape juice, mixed green salad, and fried chicken breast do not need to be removed from the patient's food tray.

4. The nurse assesses a patient who has been hospitalized for 2 days. The patient has been receiving normal saline IV at 100 mL/hr, has a nasogastric tube to low suction, and is NPO. Which assessment finding would be a priority for the nurse to report to the health care provider?

• A. Oral temperature of 100.1°F
• B. Serum sodium level of 138 mEq/L (138 mmol/L)
• C. Gradually decreasing level of consciousness (LOC)
• D. Weight gain of 2 pounds (1 kg) above the admission weight

Correct answer: C

Rationale: The priority assessment finding for the nurse to report to the healthcare provider is a gradually decreasing level of consciousness (LOC). This change in LOC could indicate fluid and electrolyte disturbances, which require immediate attention to prevent complications. While the other options such as an elevated temperature, serum sodium level, and weight gain are important to note and report, they do not indicate an urgent need for intervention compared to changes in LOC which could signify serious issues that need prompt evaluation and management.

5. The nurse is caring for a patient who has a central venous access device (CVAD). Which action by the nurse is appropriate?

• A. Avoid using friction when cleaning around the CVAD insertion site.
• B. Use the push-pause method to flush the CVAD after giving medications.
• C. Obtain an order from the healthcare provider to change the CVAD dressing.
• D. Position the patient’s face away from the CVAD during injection cap changes.

Correct answer: B

Rationale: The correct answer is B because using the push-pause method to flush the CVAD after giving medications helps remove debris from the CVAD lumen and decreases the risk for clotting. Choice A is incorrect because friction should be used when cleaning the CVAD insertion site to decrease infection risk. Choice C is incorrect because obtaining an order from the healthcare provider to change the CVAD dressing is not necessary; the dressing should be changed when damp, loose, or visibly soiled. Choice D is incorrect because the patient should face away from the CVAD during cap changes to minimize the risk of contamination.
