Nursing Elites

1. Distribution of a drug to various tissues depends on the amount of cardiac output to each type of tissue. Which tissue would receive the highest amount of cardiac output and thus the highest amount of a drug?

• A. skin
• B. adipose tissue
• C. skeletal muscle
• D. myocardium

Correct answer: D

Rationale: The correct answer is 'myocardium.' Highly perfused tissues include vital organs like the brain, heart, kidneys, adrenal glands, and liver. The myocardium, being heart muscle, receives the highest amount of cardiac output and thus the highest amount of a drug. Choices A, B, and C are incorrect because the skin and adipose tissue are poorly perfused, while skeletal muscle is less perfused compared to vital organs like the myocardium.

2. What is the 24-hour day-night cycle known as?

• A. circadian rhythm
• B. infradian rhythm
• C. ultradian rhythm
• D. non-REM rhythm

Correct answer: A

Rationale: The correct answer is circadian rhythm. Circadian rhythm refers to the rhythmic repetition of patterns that occur approximately every 24 hours, regulating various biological processes related to the day-night cycle. Infradian rhythm, which is longer than 24 hours, and ultradian rhythm, which is shorter than 24 hours, are not the correct terms for the 24-hour cycle. Non-REM rhythm does not specifically relate to the 24-hour day-night cycle, making it an incorrect choice.

3. Which action exemplifies the use of evidence-based practice in the delivery of client care?

• A. Advising a client to agree to the treatment recommended by their healthcare provider
• B. Taking a rectal temperature from a client for whom bleeding precautions have been instituted
• C. Donning sterile gloves to change an abdominal wound dressing
• D. Encouraging a client to take an herbal substance to treat their insomnia

Correct answer: C

Rationale: Evidence-based practice is an approach to client care where the nurse integrates the client’s preferences, clinical expertise, and the best research evidence to deliver quality care. Donning sterile gloves to change an abdominal wound dressing exemplifies evidence-based practice as it prevents the entrance of harmful bacteria into the wound, following best practice guidelines. The other options do not align with evidence-based practice. Advising a client to agree to a treatment does not involve integrating research evidence. Taking herbal substances may not be supported by strong research evidence and can pose risks. Additionally, rectal temperature-taking in a client with bleeding precautions can increase the risk of injury to the rectal mucosa, not aligning with best practices in care delivery.

4. During an emergency procedure, is the surgical timeout a requirement?

• A. The surgical timeout should be performed by the surgical team unless it would cause a delay leading to injury or death.
• B. No, the timeout is not necessary during an emergency procedure.
• C. No, the surgical timeout is not required in emergency procedures.
• D. Yes, the surgical timeout must be performed in all cases.

Correct answer: A

Rationale: During an emergency procedure, the surgical timeout should be performed unless doing so would cause a delay leading to injury or death. This is because the primary goal during an emergency is to swiftly address the critical situation. Choice B is incorrect as it implies that the timeout is not necessary, which is not accurate. Choice C is also incorrect as it suggests that the timeout is not required in emergency procedures, disregarding safety protocols. Choice D is incorrect as it wrongly states that the timeout must be performed in all cases without considering the potential risks associated with delays during emergencies.

5. A client with a nasogastric (NG) tube begins vomiting. What action should the nurse take?

• A. Retape the NG tube.
• B. Clamp the NG tube.
• C. Remove the NG tube.
• D. Check the NG tube placement.

Correct answer: D

Rationale: When a client with a nasogastric (NG) tube begins vomiting, the nurse should first check the NG tube placement. Vomiting can be a sign of tube displacement, which can lead to serious complications. Retaping the tube (Choice A), clamping it (Choice B), or removing it (Choice C) without first assessing its placement can be harmful or ineffective. Checking the NG tube placement is crucial as it ensures that the tube is in the correct position and prevents potential complications. Retaping the NG tube (Choice A) is incorrect because the priority is to check the placement first. Clamping the NG tube (Choice B) or removing it (Choice C) without verifying the placement can be dangerous if the tube is dislodged. Thus, these actions should not be taken before confirming the tube's position.
