A nurse is reviewing the arterial blood gas (ABG) values of a client who has chronic kidney disease. Which of the following sets of values should the nurse expect?

Choice A reason: Sodium level is not a direct measure of fluid volume. While sodium balance can influence fluid status, the serum sodium level can be affected by various factors and does not reliably indicate fluid volume increase on its own.

Choice B reason: Intake and output records are important for managing fluid balance, especially in a hospital setting. However, they can be influenced by many factors, such as incomplete recording or insensible losses, and do not provide a direct measure of fluid retention.

Choice C reason: Daily weight is considered the most reliable measure of fluid retention. Weight changes can reflect fluid balance accurately because 1 liter of fluid is roughly equivalent to 1 kilogram of body weight. In clients with chronic kidney disease, daily weight monitoring can help detect fluid volume increases or decreases promptly. For a client with chronic kidney disease, daily weight monitoring is a key assessment tool for detecting fluid volume changes. It provides a quantifiable and objective measure that can guide interventions to manage fluid balance effectively.

Choice D reason: Tissue turgor, which refers to the skin’s elasticity, is not a reliable measure of fluid volume. It can be influenced by age, edema, and other factors, and changes in turgor may not accurately reflect fluid status in the body.

Choice A: Tachypnea Tachypnea, or rapid breathing, is not typically a direct sign of increased ICP. While it can be associated with various medical conditions, it is not specifically indicative of increased ICP. However, it’s important to note that breathing patterns can change with advanced ICP changes, but these are usually characterized by irregularities rather than just increased rate. Increased intracranial pressure (ICP) is a critical condition that can occur after a traumatic brain injury (TBI). It results from the brain tissue’s response to injury, leading to swelling or bleeding within the skull. The skull is a rigid structure, so any increase in content, such as blood or edema, can lead to an increase in pressure.

Choice B: Hypotension Hypotension, or low blood pressure, is generally not associated with increased ICP. In fact, one of the signs of increased ICP is Cushing’s triad, which includes hypertension (high blood pressure), bradycardia (slow heart rate), and irregular respirations. Therefore, hypotension would not be a typical manifestation of increased ICP.

Choice C: Decreased level of consciousness A decreased level of consciousness is a hallmark sign of increased ICP. As pressure within the skull increases, it can lead to compression of the brain tissue and disruption of cerebral blood flow. This can manifest as changes in alertness, drowsiness, confusion, and in severe cases, loss of consciousness1. when monitoring a client who has sustained a TBI, the nurse should be vigilant for signs of increased ICP, with a decreased level of consciousness being a primary indicator. Other signs may include headache, nausea, vomiting, and changes in pupil size or reactivity. It is crucial to identify and treat increased ICP promptly to prevent further brain injury and potential long-term consequences.

Choice D: Bilateral weakness of extremities While bilateral weakness can be a sign of neurological damage, it is not specific to increased ICP. Increased ICP is more likely to cause global effects on consciousness and brain function rather than isolated weakness in limbs unless there is focal brain injury causing raised ICP.
