Nursing Elites

1. When collecting a sputum specimen from a client with tuberculosis, what action should the nurse take?

• A. Obtain the specimen immediately upon the client waking up.
• B. Wait one day to collect the specimen if the client cannot provide sputum.
• C. Ask the client to provide 15 to 20 ml of sputum.
• D. Wear sterile gloves when collecting the specimen.

Correct answer: A

Rationale: The correct answer is to obtain the specimen immediately upon the client waking up. Collecting sputum early in the morning provides the best sample for tuberculosis testing. Option B is incorrect because waiting a day can decrease the accuracy of the specimen. Option C is incorrect as it does not specify the optimal timing for specimen collection. Option D is incorrect as sterile gloves should be worn for infection control but do not specifically relate to the timing of specimen collection.

2. A nurse is reviewing the medical record of a client who has a history of angina and is scheduled for surgery. Which of the following findings should the nurse report to the provider?

• A. Serum potassium level of 4.2 mEq/L
• B. Blood pressure of 138/84 mm Hg
• C. Platelet count of 150,000/mm³
• D. INR of 2.0

Correct answer: D

Rationale: The correct answer is D. An INR of 2.0 is within the therapeutic range for clients receiving warfarin. It is crucial to report this finding to the provider before surgery to ensure appropriate management and potential adjustments to prevent excessive bleeding risks. Choices A, B, and C are within normal limits and do not directly impact the client's surgery preparation or risk for bleeding, so they do not require immediate reporting.

3. A client has a central venous catheter. Which of the following actions should be taken to prevent an air embolism?

• A. Keep the catheter clamped when not in use
• B. Have the client perform the Valsalva maneuver while the catheter is removed
• C. Use a non-coring needle to access the catheter
• D. Flush the catheter with 0.9% sodium chloride every 24 hours

Correct answer: B

Rationale: The correct action to prevent an air embolism in a client with a central venous catheter is to have the client perform the Valsalva maneuver while the catheter is removed. This maneuver helps to close the airway and prevent air from entering the bloodstream. Keeping the catheter clamped at all times (Choice A) is not necessary and may lead to clot formation. Using a non-coring needle (Choice C) is important for accessing the catheter but does not specifically prevent air embolism. Flushing the catheter with 0.9% sodium chloride (Choice D) helps maintain patency but does not directly prevent air embolism.

4. A nurse is caring for a client who has a sodium level of 125 mEq/L. Which of the following actions should the nurse take?

• A. Administer 0.9% sodium chloride IV
• B. Administer a hypotonic IV solution
• C. Encourage oral fluid intake
• D. Restrict oral fluid intake

Correct answer: A

Rationale: In a client with a sodium level of 125 mEq/L (hyponatremia), the nurse should administer 0.9% sodium chloride IV to help increase sodium levels. Choice B, administering a hypotonic IV solution, would further decrease the sodium level. Choice C, encouraging oral fluid intake, is contraindicated as it can dilute the sodium concentration further. Choice D, restricting oral fluid intake, could worsen the client's condition by leading to dehydration and further electrolyte imbalances.

5. A nurse is providing teaching to a client who is experiencing preterm contractions and dehydration. Which statement should the nurse make?

• A. Dehydration is treated with calcium supplements.
• B. Dehydration can increase the risk of preterm labor.
• C. Dehydration is caused by decreased hemoglobin and hematocrit.
• D. Dehydration causes gastroesophageal reflux.

Correct answer: B

Rationale: The correct statement is B: 'Dehydration can increase the risk of preterm labor.' Dehydration can lead to increased uterine irritability, potentially causing preterm contractions and labor. Choice A is incorrect as dehydration is not treated with calcium supplements but rather with fluids. Choice C is incorrect as dehydration is not caused by decreased hemoglobin and hematocrit levels but rather by a lack of fluids. Choice D is incorrect as dehydration does not directly cause gastroesophageal reflux.
