Nursing Elites

1. A client requires gastric decompression, and a nurse is inserting an NG tube. Which action should the nurse take to verify proper placement of the tube?

• A. Assess the client for a gag reflex
• B. Measure the pH of the gastric aspirate
• C. Place the end of the NG tube in water to observe for bubbling
• D. Auscultate 2.5 cm (1 in) above the umbilicus while injecting 15 mL of sterile water

Correct answer: B

Rationale: Measuring the pH of the gastric aspirate is the most reliable method to confirm proper placement of an NG tube. Gastric fluid has an acidic pH, typically ranging from 1 to 5. Assessing the client for a gag reflex (choice A) is important for airway protection but does not confirm tube placement. Placing the NG tube in water to observe for bubbling (choice C) is incorrect and not a reliable method for verifying placement. Auscultating 2.5 cm above the umbilicus while injecting sterile water (choice D) is an outdated method and is not recommended for verifying NG tube placement.

2. A client is postoperative following knee arthroplasty and requires the use of a thigh-length sequential compression device. Which of the following actions should the nurse take?

• A. Ensure two fingers can fit under the sleeves.
• B. Ensure the device is not too tight to impede circulation.
• C. Position the client comfortably before applying the device.
• D. Use the device continuously to prevent blood clots.

Correct answer: A

Rationale: The correct action for the nurse to take when applying a thigh-length sequential compression device to a postoperative client is to ensure that two fingers can fit under the sleeves. This action helps prevent the device from being too tight, which could impede circulation. Choice B is incorrect because the device should not be too tight, as it could lead to circulation issues. Choice C is incorrect as the client should be in a comfortable position, not necessarily supine. Choice D is incorrect as sequential compression devices are typically used continuously to prevent blood clots.

3. A nurse is assessing the heart sounds of a client who has developed chest pain that becomes worse with inspiration. The nurse auscultates a high-pitched scratching sound during both systole and diastole with the diaphragm of the stethoscope positioned at the left sternal border. Which of the following heart sounds should the nurse document?

• A. Pericardial friction rub
• B. Mitral stenosis
• C. Aortic regurgitation
• D. Tricuspid stenosis

Correct answer: B

Rationale: The correct answer is B: Mitral stenosis. A high-pitched scratching sound heard during both systole and diastole with the diaphragm of the stethoscope positioned at the left sternal border indicates mitral stenosis, not a pericardial friction rub. Pericardial friction rub is a to-and-fro, grating, or scratching sound due to inflamed pericardial surfaces rubbing together, typically heard in early diastole and late systole. Aortic regurgitation and tricuspid stenosis would present with different auscultatory findings compared to the described scenario, making them incorrect choices in this context.

4. A healthcare professional is preparing to administer dextrose 5% in water (D5W) 1,000-mL IV to infuse over 10 hr. How many mL/hr should the IV infusion pump be set to deliver? (Round the answer to the nearest whole number. Do not use a trailing zero.)

• A. 100 mL/hr
• B. 150 mL/hr
• C. 75 mL/hr
• D. 50 mL/hr

Correct answer: A

Rationale: To infuse 1,000 mL over 10 hr, the IV pump should be set to deliver 100 mL/hr. This calculation is derived by dividing the total volume (1,000 mL) by the total time in hours (10 hr), resulting in the infusion rate of 100 mL/hr. Choices B, C, and D are incorrect as they do not accurately reflect the correct calculation for this scenario.

5. What advice should the client be given if they are feeling dizzy upon standing after taking a diuretic for hypertension?

• A. Avoid standing up too quickly.
• B. Increase fluid intake to stay hydrated.
• C. Eat more salt to help retain fluids.
• D. Wear compression stockings during the day.

Correct answer: A

Rationale: The correct advice for a client feeling dizzy upon standing after taking a diuretic for hypertension is to avoid standing up too quickly. Diuretics can lead to orthostatic hypotension, causing dizziness upon sudden position changes. Increasing fluid intake can exacerbate the issue by further lowering blood pressure. Eating more salt might counteract the diuretic's effects but is not the primary intervention for orthostatic hypotension. Compression stockings are more relevant for venous insufficiency than for orthostatic hypotension.
