Nursing Elites

1. When admitting a 5-month-old who has vomited 9 times in the past 6 hours, what should the healthcare provider observe for signs of which overall imbalance?

• A. Metabolic acidosis
• B. Metabolic alkalosis
• C. Increased serum hemoglobin levels
• D. Decreased serum potassium levels

Correct answer: B

Rationale: When a 5-month-old infant vomits multiple times, there is a risk of developing metabolic alkalosis due to the loss of stomach acid. Metabolic alkalosis is characterized by elevated pH and bicarbonate levels. It is caused by the loss of hydrogen ions from the body, often through vomiting. Metabolic acidosis (choice A) is unlikely in this scenario because it is more commonly associated with conditions like renal failure or diabetic ketoacidosis. Choice C, increased serum hemoglobin levels, is not typically a direct consequence of vomiting. Choice D, decreased serum potassium levels, may occur with vomiting but is not the primary concern when a patient is vomiting excessively.

2. What intervention should be implemented by the LPN to reduce the risk of aspiration in a client with a nasogastric tube receiving continuous enteral feedings?

• A. Elevate the head of the bed to 30-45 degrees.
• B. Check residual volumes every 4 hours.
• C. Verify tube placement every shift.
• D. Flush the tube with water every 4 hours.

Correct answer: A

Rationale: Elevating the head of the bed to 30-45 degrees is crucial in reducing the risk of aspiration because it helps keep the gastric contents lower than the esophagus, thereby promoting proper digestion and preventing reflux. This position also aids in reducing the likelihood of regurgitation and aspiration of gastric contents. Checking residual volumes every 4 hours is important for monitoring feeding tolerance but does not directly address the risk of aspiration. Verifying tube placement every shift is essential for ensuring the tube is correctly positioned within the gastrointestinal tract but does not directly reduce the risk of aspiration. Flushing the tube with water every 4 hours may help maintain tube patency and prevent clogging, but it does not specifically address the risk of aspiration associated with nasogastric tube feedings.

3. During a peripheral vascular assessment, a healthcare professional places the bell of the stethoscope on a client's neck and hears an audible vascular sound associated with turbulent blood flow. This sound indicates which of the following?

• A. Narrowed arterial lumen
• B. Distended jugular veins
• C. Impaired ventricular contraction
• D. Asynchronous closure of the aortic and pulmonic valve

Correct answer: A

Rationale: The correct answer is A: Narrowed arterial lumen. Arterial bruits are abnormal sounds caused by turbulent blood flow through narrowed or occluded arteries. This turbulent flow creates a blowing sound, which is heard as an arterial bruit. Distended jugular veins (choice B) are typically associated with venous issues, not arterial abnormalities. Impaired ventricular contraction (choice C) and asynchronous closure of the aortic and pulmonic valve (choice D) are not directly related to the audible vascular sound described in the scenario.

4. A nurse is caring for a client who is unstable and has vital signs measured every 15 minutes by an electronic blood pressure machine. The nurse notices the machine begins to measure the blood pressure at varied intervals and the readings are inconsistent. Which of the following actions should the nurse take?

• A. Discontinue the machine and measure the blood pressure manually every 15 minutes.
• B. Adjust the machine settings.
• C. Clean the machine to ensure accuracy.
• D. Increase the frequency of the readings.

Correct answer: B

Rationale: In this scenario, the nurse should adjust the machine settings. If the electronic blood pressure machine is providing varied intervals and inconsistent readings, it indicates a potential malfunction. Changing the settings may help correct the issue and ensure accurate measurements. Discontinuing the machine and measuring manually every 15 minutes (Choice A) may be time-consuming and impractical. Cleaning the machine (Choice C) is important for routine maintenance but may not address the current issue of varied intervals and inconsistent readings. Increasing the frequency of the readings (Choice D) does not address the problem of inaccurate measurements caused by the malfunctioning machine.

5. The nurse is caring for a patient who is immobile and needs to be turned every 2 hours. The patient has poor lower extremity circulation, and the nurse is concerned about irritation of the patient's toes. Which device will the nurse use?

• A. Hand rolls
• B. A foot cradle
• C. A trapeze bar
• D. A trochanter roll

Correct answer: B

Rationale: A foot cradle is the correct choice for this situation. A foot cradle is used to reduce pressure on the tips of a patient's toes in individuals with poor lower extremity circulation. Hand rolls are not designed to address toe irritation specifically. A trapeze bar is used to assist patients with repositioning in bed, and a trochanter roll is used to support the hips and prevent external rotation of the legs, neither of which directly address toe irritation in this scenario.
