Correct Answer: A

Rationale: The correct answer is 'Fraud.' Identifying oneself as a nurse without a license defrauds the public and can lead to prosecution. A tort is a wrongful act in breach of a legal duty imposed by law; malpractice is the failure to act appropriately as a nurse or acting in a way that harm comes to the client; and negligence is failing to perform care. In this scenario, the key issue is the misrepresentation of licensure status, which constitutes fraud. Therefore, choices B, C, and D are incorrect.

Correct Answer: C

Rationale: When a client is receiving total parenteral nutrition (TPN), monitoring blood glucose levels is crucial as TPN solutions contain high amounts of glucose. This monitoring helps prevent hyperglycemia or hypoglycemia. Evaluating hemoglobin (choice A) is not directly related to TPN administration. Creatinine (choice B) is more relevant for assessing kidney function. White blood cell count (choice D) is important for evaluating immune function and infection, but not specifically tied to TPN administration.

Correct Answer: B

Rationale: Choice B is the best response as it shows empathy, acknowledges the patient's feelings, and opens the door for discussion about potential triggers for anxiety. This approach helps the patient explore the root cause of his anxiety and provides an opportunity for therapeutic communication. Choice A dismisses the patient's feelings and offers false reassurance, which may not address the underlying issue. Choices C and D do not encourage the patient to express his emotions or delve into the reasons behind his anxiety, hindering the therapeutic process.

Correct Answer: A

Rationale: When a client reports talking to voices, the nurse should engage in a gentle touch to help the client return to reality. It is important for the nurse to acknowledge the client's experience and attempt to redirect them gently. Touch can provide grounding and connection. Asking the client to describe what is happening can be overwhelming and might exacerbate the situation. Leaving the client alone may not be safe or therapeutic as the client may need support. Telling the client there are no voices denies their reality and is not helpful in managing their experience.

Correct Answer: C

Rationale: The client is experiencing compensated respiratory acidosis. The pH is within the normal range but is lower than 7.40, indicating acidity. The elevated CO2 level and low O2 level suggest respiratory involvement. The slightly elevated HCO3 level indicates a compensatory mechanism. In respiratory acidosis, the pH will be inversely related to the CO2 and bicarb levels, with elevated CO2 and HCO3 levels contributing to acidosis. Choices A, B, and D are incorrect because they do not align with the presented blood gas values and the compensatory response observed in this case.
