Nursing Elites

1. 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.

2. A nurse is caring for a client who is receiving chemotherapy. Which of the following findings should the nurse report to the provider?

• A. Alopecia
• B. Weight gain of 1 kg (2.2 lb) in 24 hours
• C. White blood cell count of 6,000/mm³
• D. Temperature of 37.2°C (99°F)

Correct answer: B

Rationale: The correct answer is B. A weight gain of 1 kg (2.2 lb) in 24 hours is concerning as it indicates fluid retention, which can be a sign of complications in clients receiving chemotherapy. Rapid weight gain can be associated with conditions like fluid overload or electrolyte imbalances, which need prompt medical attention. Choices A, C, and D are not typically immediate concerns related to chemotherapy. Alopecia (choice A) is a common side effect of chemotherapy, a white blood cell count of 6,000/mm³ (choice C) falls within the normal range, and a temperature of 37.2°C (99°F) (choice D) is slightly elevated but not a critical finding in this context.

3. A nurse is reviewing the medical record of a client who is receiving total parenteral nutrition (TPN). Which of the following findings should the nurse report to the provider?

• A. Glucose 180 mg/dL
• B. Sodium 136 mEq/L
• C. Potassium 3.8 mEq/L
• D. Albumin 3.5 g/dL

Correct answer: A

Rationale: The correct answer is A: "Glucose 180 mg/dL." Elevated glucose levels in a client receiving TPN may indicate hyperglycemia, which can lead to complications such as osmotic diuresis, dehydration, and electrolyte imbalances. It is essential to report this finding to the provider for further evaluation and management. Choices B, C, and D are within normal ranges and do not indicate immediate concerns related to TPN administration.

4. Which electrolyte imbalance is most concerning in a patient taking digoxin?

• A. Monitor potassium levels
• B. Monitor calcium levels
• C. Monitor sodium levels
• D. Monitor magnesium levels

Correct answer: A

Rationale: The correct answer is to monitor potassium levels. Patients taking digoxin are at risk of developing toxicity due to hypokalemia. Low potassium levels can potentiate the toxic effects of digoxin on the heart, leading to serious arrhythmias. Monitoring calcium levels (Choice B) is not the primary concern in patients taking digoxin. While calcium levels play a role in cardiac function, hypocalcemia is not directly associated with digoxin toxicity. Monitoring sodium levels (Choice C) is important for other conditions but is not the primary concern in a patient taking digoxin. Monitoring magnesium levels (Choice D) is also essential, but hypomagnesemia is not as directly linked to digoxin toxicity as hypokalemia.

5. How should signs of dehydration in an elderly patient be assessed?

• A. Monitor skin turgor
• B. Check for dry mucous membranes
• C. Monitor for sunken eyes
• D. Check capillary refill

Correct answer: A

Rationale: Corrected Rationale: Monitoring skin turgor is a reliable method to assess dehydration in elderly patients. Skin turgor refers to the skin's elasticity or the skin's ability to return to its normal position after being pinched. In dehydration, the skin loses its elasticity, becoming less flexible and slower to return to its original state. Checking for dry mucous membranes (Choice B), monitoring for sunken eyes (Choice C), and checking capillary refill (Choice D) are all relevant assessments in dehydration but are not as specific or sensitive as monitoring skin turgor. Dry mucous membranes and sunken eyes are indicators of dehydration, while capillary refill is more related to circulatory status and less specific to dehydration.
