The client is scheduled to receive 30 grams of lactulose orally every 12 hours. An oral solution containing 5 g/10 mL is available. How many mL should be poured into the medication cup to administer the required dose?

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.

Choice A reason: A BUN level of 8 mg/dL and creatinine level of 0.7 mg/dL are within normal ranges and would not be expected in a client with CKD².

Choice B reason: Elevated BUN and creatinine levels, such as 45 mg/dL and 8 mg/dL respectively, are indicative of impaired kidney function, which is consistent with CKD².

Choice C reason: A BUN level of 10 mg/dL and creatinine level of 0.3 mg/dL are lower than the expected values for a client with CKD, indicating better kidney function than typically seen in CKD².

Choice D reason: A BUN level of 23 mg/dL and creatinine level of 1.0 mg/dL may be slightly elevated but are not as indicative of CKD as the values in choice B².
