A nurse is observing a newly licensed nurse perform hand hygiene. Which of the following actions by the newly licensed nurse indicates an understanding of the procedure?
- A. Holds their hands below elbows while rinsing off soap
- B. Uses hot water to wash their hands
- C. Turns off the faucet with their hands
- D. Washes their hands for 10 seconds
Correct Answer: A
Rationale: The correct answer is A because holding hands below elbows while rinsing off soap prevents contamination of clean hands by dirty water. This action ensures proper hand hygiene by maintaining a unidirectional flow of water from clean to dirty areas. Choice B using hot water is incorrect as it may cause skin irritation. Choice C turning off the faucet with hands can reintroduce contamination. Choice D washing hands for only 10 seconds is insufficient for effective hand hygiene.

A nurse is preparing to administer furosemide 30 mg IV bolus stat. Available is furosemide injection 10 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: 3
Rationale: To determine the correct mL of furosemide to administer, we can use the formula: Desired dose (30 mg) / Available dose (10 mg/mL) = mL to administer. So, 30 mg / 10 mg/mL = 3 mL. The correct answer is therefore 3 mL.
Choice A: Incorrect. This answer does not provide the correct calculation based on the given information.
Choice B: Incorrect. This answer does not demonstrate the correct calculation based on the given information.
Choice C: Incorrect. This answer does not reflect the accurate calculation using the provided data.
Choice D: Incorrect. This choice does not show the correct calculation based on the information presented.
Choice E: Incorrect. This response does not align with the correct calculation method for determining the mL to administer.
Choice F: Incorrect. This choice does not offer the accurate calculation based on the provided data.
Choice G: Incorrect. This answer does not demonstrate the correct calculation using the
A nurse is gathering evidence-based practice on catheter-associated urinary tract infections (CAUTI). Which of the following roles is the nurse performing?
- A. Researcher
- B. Nurse manager
- C. Case manager
- D. Educator
Correct Answer: A
Rationale: The correct answer is A: Researcher. The nurse is gathering evidence-based practice on CAUTI, which involves conducting research to gather relevant information, analyze data, and draw conclusions based on evidence. This role aligns with the responsibilities of a researcher who systematically investigates a topic to contribute to the body of knowledge. The other choices are incorrect because: B: Nurse managers oversee nursing staff and operations, C: Case managers coordinate patient care, and D: Educators focus on teaching and disseminating knowledge. In this scenario, the nurse's primary role is to gather evidence through research, making option A the most appropriate choice.
A nurse is receiving a telephone prescription for a client from a provider. Which of the following actions should the nurse take when transcribing the prescription?
- A. Use the provider’s initials after the prescription
- B. Repeat the prescription to the provider
- C. Write the prescription in shorthand
- D. Read back the prescription to the provider
Correct Answer: D
Rationale: The correct answer is D: Read back the prescription to the provider. This is crucial to ensure accuracy and prevent errors. By reading back the prescription, the nurse confirms understanding and allows the provider to clarify any misunderstandings immediately. This step promotes patient safety and effective communication.
Choice A (Use the provider’s initials after the prescription) is incorrect because it does not address the need for verification of the prescription details. Choice B (Repeat the prescription to the provider) is not as effective as reading back, as it may not ensure complete accuracy. Choice C (Write the prescription in shorthand) can lead to misinterpretation and errors.
A nurse is teaching a class about pharmacodynamics. The nurse should include that which of the following medication levels occurs when a medication is at the lowest serum concentration?
- A. Trough
- B. Peak
- C. Half-life
- D. Toxic
Correct Answer: A
Rationale: The correct answer is A: Trough. The trough level represents the lowest serum concentration of a medication in the body, usually measured just before the next dose is administered. This is important in monitoring the effectiveness and safety of the drug. Peak levels (B) indicate the highest concentration. Half-life (C) refers to the time it takes for half of the drug to be eliminated from the body. Toxic levels (D) are when the drug concentration is too high and can lead to harmful effects. Other choices are not relevant to the lowest serum concentration.
A nurse is caring for four clients who have drainage tubes. Which of the following clients should the nurse recognize as being at risk for hypokalemia?
- A. The client who has a nasogastric (NG) tube to suction
- B. The client who has a chest tube to water seal
- C. The client who has an indwelling urinary catheter to gravity drainage
- D. The client who has a tracheostomy tube attached to humidified oxygen
Correct Answer: A
Rationale: The correct answer is A: The client who has a nasogastric (NG) tube to suction. Suctioning through the NG tube can lead to loss of gastric contents, including potassium, which can result in hypokalemia. The other choices do not directly affect potassium levels. B: A chest tube to water seal is used to drain air or fluid from the pleural space, not likely to cause hypokalemia. C: An indwelling urinary catheter to gravity drainage does not impact potassium levels. D: A tracheostomy tube with humidified oxygen does not affect potassium levels. Therefore, the client with the NG tube to suction is at risk for hypokalemia due to potential potassium loss.
