Nursing Elites

1. An adult client undergoes various diagnostic tests to determine the pumping ability of the heart. The nurse notes that the results of these tests indicate that the client's cardiac output is 5 L/min. The nurse makes which conclusion?

• A. The client has a low cardiac output.
• B. The client has a high cardiac output.
• C. The client has a normal cardiac output.
• D. The client will need a blood transfusion.

Correct answer: C

Rationale: A cardiac output of 5 L/min falls within the normal range for a resting adult, which typically ranges between 4 and 6 L/min. Cardiac output is calculated as the stroke volume (volume of blood in each systole) multiplied by the heart rate. Therefore, a cardiac output of 5 L/min is considered normal. Choices A and B are incorrect as they misinterpret the result as either low or high, which is not the case based on the provided information. Choice D is unrelated to the client's cardiac output and thus incorrect.

2. An LPN is tasked with checking the narcotic count on a medical-surgical unit. Which statement by the LPN requires further investigation?

• A. "I need a witness when I waste the leftover narcotics in the client's PCA pump."?
• B. "I am going to check the facility's policy for how to dispose of this controlled substance."?
• C. "I left the narcotics box unlocked after confirming the beginning of shift count was correct."?
• D. "The end of shift narcotics count is incorrect and needs to be reported."?

Correct answer: C

Rationale: The LPN's statement about leaving the narcotics box unlocked after confirming the beginning of shift count was correct requires further investigation. Narcotics should be locked and kept in a secure place during the shift to prevent unauthorized access and ensure patient safety. This statement raises concerns about medication security, which is critical in preventing diversion and ensuring patient safety. The other statements demonstrate appropriate actions: A) The LPN acknowledges the need for a witness when wasting leftover narcotics, ensuring proper documentation and accountability during medication waste. B) Checking the facility's policy for proper disposal of controlled substances shows awareness of regulatory compliance regarding controlled substances. D) Recognizing an incorrect end-of-shift narcotics count and planning to report it reflects the LPN's responsibility in maintaining accurate records and addressing discrepancies, which is essential for medication safety and accountability.

3. What is the threshold of dextrose concentrations that can safely be administered through a peripheral IV?

• A. Dextrose concentrations below 20% can be safely administered through a peripheral IV; dextrose concentrations above 20% should not be administered through a peripheral IV.
• B. Dextrose concentrations below 5% can be safely administered through a peripheral IV; dextrose concentrations above 5% should not be administered through a peripheral IV.
• C. Dextrose concentrations below 10% can be safely administered through a peripheral IV; dextrose concentrations above 10% should not be administered through a peripheral IV.
• D. Dextrose concentrations above 5% can be safely administered through a peripheral IV; dextrose concentrations below 5% should not be administered through a peripheral IV.

Correct answer: C

Rationale: Dextrose concentrations below 10% are considered safe for administration through a peripheral IV, as concentrations above this threshold can lead to phlebitis, causing inflammation of the vein. Concentrations above 10% should not be administered through a peripheral IV to prevent vein irritation. Choice A is incorrect because concentrations above 20% are too high for a peripheral IV. Choice B is incorrect as dextrose concentrations below 5% are too low to be effective. Choice D is incorrect because the statement is reversed, suggesting that concentrations above 5% are safe, which is not true.

4. The school nurse is conducting health screenings on schoolchildren. During the screening, she identifies a child with the behavioral characteristics of attention deficit disorder. Which of the following behaviors is consistent with this disorder?

• A. slow speech development
• B. overreaction to stimuli from the surroundings
• C. inability to carry on a conversation
• D. concrete thinking

Correct answer: B

Rationale: The correct answer is 'overreaction to stimuli from the surroundings.' Children with attention deficit disorder often exhibit hypersensitivity to stimuli, leading to overreactions. Slow speech development is not a hallmark of attention deficit disorder; it is more associated with other learning disabilities. While children with this disorder may have difficulty focusing, they can usually carry on a conversation. Concrete thinking is not a common characteristic of attention deficit disorder, as individuals with this disorder may struggle with abstract thinking and impulsivity.

5. How often should a 5-year-old child undergo a dental examination?

• A. Every 6 months
• B. Whenever a new primary tooth erupts
• C. Once a year
• D. Every 3 months

Correct answer: A

Rationale: For a 5-year-old child, dental examinations should be conducted every 6 months. This frequency allows for early detection of dental issues and promotes good oral health. Choices B, C, and D are incorrect because waiting for a new primary tooth to erupt, having an examination once a year, or every 3 months are not the recommended intervals for dental check-ups in this age group. It is essential to adhere to the standard guideline of every 6 months to ensure regular monitoring and preventive care for the child's dental health.
