A nurse is providing care for four patients. Which patient should the nurse evaluate first for cognitive impairment?

Rationale for Choice A: Ensuring the client is warm
While maintaining client warmth is important for comfort and to prevent hypothermia, it is not the immediate priority upon arrival in the postoperative unit. Thermoregulation can be addressed after more urgent assessments have been completed.
Rationale for Choice B: Participating in hand-off report
A thorough hand-off report is essential for continuity of care, but it does not take precedence over assessing the client's immediate physiological status. The nurse can gather information from the report while simultaneously performing essential assessments.
Rationale for Choice C: Checking the surgical dressings
Monitoring surgical dressings is a crucial aspect of postoperative care, but it does not take priority over assessing fluid and blood output. Excessive bleeding or fluid shifts can rapidly compromise the client's hemodynamic stability and require prompt intervention.
Rationale for Choice D: Assessing fluid and blood output
This is the priority action for several reasons:
Monitoring for Hemorrhage: Early detection of excessive bleeding is crucial to prevent hypovolemic shock, a life-threatening complication. Postoperative bleeding can occur internally or externally, and prompt assessment of fluid and blood output allows for timely interventions to control bleeding and maintain hemodynamic stability.

Assessing Fluid Balance: Maintaining fluid balance is essential for optimal organ function and electrolyte balance. Postoperative clients are at risk for fluid imbalances due to blood loss, fluid shifts, and the use of diuretics or IV fluids. Assessing fluid intake and output helps to identify and address fluid imbalances early.
Evaluating Renal Function: Urine output is a key indicator of renal function. Postoperative clients are at risk for acute kidney injury due to factors such as hypotension, blood loss, and nephrotoxic medications. Assessing urine output helps to detect early signs of kidney dysfunction and initiate appropriate interventions.
Guiding Fluid and Blood Product Replacement: The assessment of fluid and blood output provides essential information to guide the administration of fluids and blood products as needed. This ensures that the client's fluid status and oxygen-carrying capacity are maintained within safe parameters.
Therefore, assessing fluid and blood output takes priority as it allows the nurse to identify and address potential life- threatening complications promptly, as well as guide interventions to maintain fluid balance and organ function.

Choice A rationale:
While PICCs are typically intended for shorter-term use (up to 12 weeks), the fact that a PICC has been in place for 4 weeks is not, in itself, an immediate cause for concern. Regular assessment of the catheter and site is crucial, but the duration of placement alone does not warrant immediate attention.
Choice B rationale:
While it's generally recommended to change PICC dressings every 7 days, a dressing that is 3 days old is not an immediate emergency. The nurse should prioritize changing the dressing as soon as possible, but it does not require the same level of urgency as other potential complications.
Choice C rationale:
A missing securement device is a concern because it can increase the risk of catheter dislodgement or migration. However, it does not necessarily indicate an immediate threat to the patient's well-being. The nurse should promptly address the missing securement device, but it would not be the most pressing issue compared to swelling in the extremity.
Choice D rationale:
Swelling in the upper extremity where the PICC is located is a significant finding that demands immediate attention. It can be a sign of several serious complications, including:
Thrombosis: A blood clot within the vein, which can obstruct blood flow and lead to pain, swelling, and potentially more severe consequences like deep vein thrombosis (DVT) or pulmonary embolism (PE).
Infection: Inflammation and infection at the insertion site or within the bloodstream, which can cause swelling, redness, warmth, and pain. If left untreated, infection can progress to sepsis, a life-threatening condition.
Phlebitis: Inflammation of the vein, which can cause pain, redness, and swelling along the vein.
Infiltration: Leakage of fluids or medications into the surrounding tissue, leading to swelling and discomfort.
Prompt action is crucial in these cases to prevent further complications and ensure patient safety. The nurse should immediately notify the appropriate healthcare provider, initiate necessary interventions, and closely monitor the patient's condition.
