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?

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. Which NSAID is comparable to morphine in efficacy?

Correct answer: C

Rationale: The correct answer is Toradol. Toradol is the first injectable NSAID that has been found to be comparable to morphine in terms of efficacy. Feldene (choice A) is not known for being comparable to morphine in efficacy. Stodal (choice B) is a homeopathic cough syrup and not an NSAID. Elavil (choice D) is a tricyclic antidepressant and not an NSAID, so it is not comparable to morphine in efficacy. Therefore, Toradol is the most appropriate choice as it matches the description provided in the question.

3. The nurse is caring for a client awaiting test results on a biopsy. The client is unconscious, and the physician informs the client's spouse that the biopsy came back positive for cancer. The spouse asks the nurse if they will not share this news with the client because they would prefer the client be unaware of the diagnosis. Which of the following responses is most appropriate?

Correct answer: B

Rationale: The correct response is, "For ethical reasons, I am unable to withhold this information from the client."? The ethical principle of veracity requires that the nurse is truthful with the client and does not withhold information even if it is requested by the family. Choice A is incorrect because seeking a psychiatrist's confirmation is not necessary to uphold the ethical principle of truth-telling. Choice C is incorrect as implying that signing paperwork overrides the nurse's ethical obligation to be honest with the client is inappropriate. Choice D is also incorrect as a durable power of attorney is not relevant in this situation where the spouse is asking the nurse to withhold information.

4. The LPN is checking for residual before administering enteral feeding through a PEG tube. Which of these steps is incorrect?

Correct answer: C

Rationale: The incorrect step is choice C. The residual should be discarded before administering the tube feeding. Discarding the residual is essential to prevent contamination and ensure accurate measurement of the enteral feeding. Elevating the head of the bed by at least 30 degrees (choice A) is correct as it helps prevent aspiration during feeding. Testing the pH level of the residual (choice D) ensures proper placement of the tube. Withholding feeding if the residual is greater than 200mL (choice B) is crucial to prevent overfeeding, making this statement correct.

5. The LPN needs to delegate a task to the nurse aide who is new to the unit. Which of these is the best option for the nurse to choose in proceeding?

Correct answer: B

Rationale: Delegation is transferring responsibility for a task but sharing its accountability. It is the delegator's responsibility to ensure that the delegatee understands the task before it is performed and to follow up afterward to ensure it was completed correctly and safely. Option B is the best choice because it allows the nurse to observe the nurse aide performing the task without pressure, which can provide insights into the aide's abilities and understanding. This method also allows for immediate feedback and correction if needed. Choice A is incorrect because confirming understanding alone may not provide a complete picture of the aide's competence in performing the task. Choice C is incorrect as it suggests supervising only if needed, which may not provide adequate oversight for a new nurse aide. Choice D is incorrect because supervising the task being performed does not allow for an objective assessment of the aide's abilities and understanding.
