Correct Answer: A

Rationale: A GCS score of 14 indicates that the client is neurologically stable without indications of increased ICP. It suggests that the client's neurological status is relatively intact, with only mild impairment, if any. This finding reassures the nurse that there are currently no signs of deterioration or immediate need for intervention. Choice B is incorrect because a GCS score of 14 does not necessarily indicate immediate risk for neurological deterioration. Choice C is incorrect as mild cognitive impairment is not typically inferred from a GCS score of 14. Choice D is incorrect as immediate medical intervention is not warranted based on a GCS score of 14 without other concerning symptoms.

Correct Answer: A

Rationale: The correct answer is A. Anuria for the last 12 hours. Anuria, the absence of urine output, indicates complete kidney failure and is a medical emergency that requires immediate attention. In acute kidney injury (AKI), the kidneys are unable to filter waste from the blood effectively, leading to a buildup of toxins and electrolyte imbalances like elevated blood potassium levels. Tachycardia and hypotension (choice B) can be seen in AKI but do not reflect the urgency of addressing anuria. Decreased urine output (choice C) is concerning but not as critical as the absence of urine production. Elevated blood urea nitrogen (BUN) levels (choice D) are indicative of kidney dysfunction but do not demand immediate action as anuria does.

Correct Answer: D

Rationale: The best initial response by the nurse when the client reports muscle weakness is to ask the client to describe the changes that have occurred. This approach allows the nurse to gain a better understanding of the client's experience, the extent of weakness, any associated symptoms, and potential triggers. By actively listening to the client's description, the nurse can gather valuable information that will aid in a comprehensive assessment and development of a tailored care plan. Choice A is incorrect because assuming muscle weakness is solely due to aging without further assessment can lead to overlooking potential underlying causes. Choice B is incorrect as observing for signs of muscle atrophy should come after gathering information directly from the client. Choice C is incorrect as reviewing diagnostic test results should not be the initial step when the client's current experience is being shared.

Correct Answer: C

Rationale: The correct needle to use for administering intravenous fluids via an implanted port is a non-coring (Huber) needle. This type of needle is specifically designed to access implanted ports without coring the septum, which helps prevent damage. Choice A, the one with the clamp and no needle, is incorrect as it does not describe a needle suitable for accessing an implanted port. Choice B, a butterfly needle, is not typically used for accessing implanted ports. Choice D, a standard hypodermic needle, is not ideal for accessing ports as it can damage the septum.

Correct Answer: A

Rationale: The correct answer is A, 'Increased fatigue.' In a client with CKD receiving erythropoietin therapy, increased fatigue can be a sign of polycythemia, a condition characterized by an elevated red blood cell count. This can lead to increased blood viscosity and raise the risk of thromboembolic events, necessitating immediate intervention. Elevated blood pressure (choice B) is a common concern in CKD but does not require immediate intervention in this context. Headache (choice C) may be related to elevated blood pressure but is not the most critical finding requiring immediate attention. Elevated hemoglobin (choice D) is an expected outcome of erythropoietin therapy and does not require immediate intervention unless excessively high.
