The nurse inserts a urinary catheter and obtains a scant amount of dark amber output. Which intervention should the nurse implement first? (Please scroll and view each tab's information in the client's medical record before selecting the answer.)
Initiate continuous dopamine infusion at 2 mcg/kg/minute.
Administer promethazine 25 mg slow intravenous (IV) push every 4 hours.
Begin potassium chloride 10 mEq over 1 hour per secondary infusion.
Give a bolus of 0.9% sodium chloride 1,000 ml over 30 minutes.
The Correct Answer is D
A) Incorrect - Initiating continuous dopamine infusion is not a priority in this situation. The client's low blood pressure and electrolyte imbalances require more immediate attention.
B) Incorrect - Administering promethazine addresses symptoms like nausea and vomiting, but it doesn't address the primary issue of hypovolemia and low blood pressure.
C) Incorrect - Administering potassium chloride without addressing the fluid deficit can be dangerous and may lead to further electrolyte imbalances.
D) Correct- The client's vital signs and laboratory results indicate hypovolemia (low blood pressure, low sodium, and low potassium). The immediate priority is to address the fluid deficit and correct the electrolyte imbalances. Administering a bolus of 0.9% sodium chloride (normal saline) will help increase intravascular volume and improve blood pressure, as well as correct the electrolyte imbalances to some extent.

Correct Answer is ["A","C","D","E"]
Explanation
Fever increases fluid loss through perspiration.
Increased respiratory rate can lead to increased fluid loss through evaporation. Increased nasal secretions can result in fluid loss.
High oxygen flow can cause drying of the mucous membranes and increase fluid requirements.
The following findings do not necessarily indicate increased fluid requirements: Blood pressure alone does not indicate increased fluid requirements.
Oxygen saturation within the normal range does not indicate increased fluid requirements.
Although urine output is important to assess hydration status, 12 mL of urine may not necessarily indicate increased fluid requirements.
Heart rate alone does not indicate increased fluid requirements.
Correct Answer is C
Explanation
The correct answer is choice C. Observe both lower extremities for redness and swelling.
Choice A rationale:
Palpating all peripheral pulse points for volume and strength is important for assessing circulation, but it does not directly evaluate the effectiveness of intermittent pneumatic compression (IPC) devices.IPC devices are primarily used to prevent deep vein thrombosis (DVT) and improve venous return, so monitoring for signs of DVT is more relevant.
Choice B rationale:
Monitoring the amount of drainage from the client’s incision is crucial for assessing wound healing and detecting potential infections, but it is not related to the effectiveness of IPC devices.
Choice C rationale:
Observing both lower extremities for redness and swelling is the most important assessment for evaluating the effectiveness of IPC devices. Redness and swelling can be signs of DVT, which IPC devices are designed to prevent.Therefore, this assessment directly measures whether the devices are functioning as intended.
Choice D rationale:
Evaluating the client’s ability to use an incentive spirometer is important for preventing postoperative pulmonary complications, but it does not assess the effectiveness of IPC devices.
