Nursing Elites

1. A healthcare provider is caring for a client who has a heart murmur. The healthcare provider is preparing to auscultate the pulmonary valve. Over which of the following locations should the healthcare provider place the bell of the stethoscope?

• A. Second intercostal space at the left sternal border
• B. Fifth intercostal space at the midclavicular line
• C. Fourth intercostal space at the left sternal border
• D. Fifth intercostal space at the left anterior axillary line

Correct answer: A

Rationale: The correct location to auscultate the pulmonary valve is the second intercostal space at the left sternal border. This area is where the pulmonary valve can best be heard due to its anatomical position. Choice B, the fifth intercostal space at the midclavicular line, is the location for auscultating the mitral valve. Choice C, the fourth intercostal space at the left sternal border, is the area for the tricuspid valve. Choice D, the fifth intercostal space at the left anterior axillary line, is the site for listening to the mitral valve as well. Therefore, option A is the correct choice for auscultating the pulmonary valve.

2. A healthcare professional in a provider's office is reviewing the laboratory findings of a client who reports chills and aching joints. Which of the following findings should the healthcare professional identify as an indication that the client has an infection?

• A. WBC 15,000/mm³
• B. Hemoglobin 12 g/dL
• C. Platelet count 300,000/mm³
• D. Sodium 140 mEq/L

Correct answer: A

Rationale: An elevated white blood cell count (WBC 15,000/mm³) is a common indicator of infection as the body increases WBC production to fight off pathogens. In conditions like infections, inflammation, or stress, the WBC count can rise. The other options, hemoglobin, platelet count, and sodium levels, are not typically specific indicators of infection. Hemoglobin measures the oxygen-carrying capacity of red blood cells, platelet count assesses clotting ability, and sodium levels indicate electrolyte balance.

3. In a mass casualty scenario at a child day care center, which child would the triage nurse prioritize for treatment last?

• A. An infant with intermittent bulging anterior fontanel between crying episodes
• B. A toddler with severe deep abrasions covering over 98% of the body
• C. A preschooler with 1 lower leg fracture and the other leg with an upper leg fracture
• D. A school-age child with singed eyebrows and hair on the arms

Correct answer: B

Rationale: In a mass casualty scenario, the triage nurse would prioritize the toddler with severe deep abrasions covering over 98% of the body for treatment last. This child is categorized as 'expectant' due to the extensive injuries, which are unlikely to be survivable even with immediate treatment. The other choices describe injuries that are serious but have a higher likelihood of survival with appropriate and timely intervention. The infant with an intermittent bulging anterior fontanel may have increased intracranial pressure requiring urgent evaluation, the preschooler with leg fractures can be stabilized and treated effectively, and the school-age child with singed hair likely has superficial burns which can be managed promptly.

4. Heparin 20,000 units in 500 ml D5W at 50 ml/hour has been infusing for 5.5 hours. How much heparin has the client received?

• A. 11,000 units.
• B. 13,000 units.
• C. 15,000 units.
• D. 17,000 units.

Correct answer: A

Rationale: To calculate the total amount of heparin received, multiply the infusion rate (50 ml/hour) by the total infusion time (5.5 hours). This results in 275 ml of the solution infused. Since there are 20,000 units of heparin in 500 ml, there are 800 units per ml. Therefore, 275 ml contains 220,000 units. However, the heparin is diluted in 500 ml, so the client has received half of this amount, which is 110,000 units. Therefore, the correct answer is 11,000 units. Choices B, C, and D are incorrect as they do not reflect the correct calculation based on the provided information.

5. What action should the LPN/LVN take to prevent postoperative complications in a client who has undergone abdominal surgery?

• A. Encourage the client to use an incentive spirometer regularly.
• B. Assist the client in ambulating as soon as possible.
• C. Position the client in high Fowler's position.
• D. Encourage the client to cough and deep breathe regularly.

Correct answer: A

Rationale: Encouraging the client to use an incentive spirometer regularly is crucial in preventing postoperative complications after abdominal surgery. This action helps prevent atelectasis by promoting lung expansion and improving air exchange in the lungs, reducing the risk of respiratory complications. Assisting the client in ambulating early is important for preventing issues like deep vein thrombosis but may not directly address respiratory concerns postoperatively. Positioning the client in high Fowler's position can help with respiratory distress but is not as specific to preventing postoperative respiratory complications as using an incentive spirometer. While encouraging the client to cough and deep breathe is generally beneficial for lung expansion, using an incentive spirometer is more effective and targeted in preventing atelectasis after abdominal surgery.
