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 D
Explanation
The presence of purulent drainage at the wound indicates a potential infection, and monitoring the client's WBC count is an important laboratory value to assess for signs of infection. An elevated WBC count, specifically an increase in the neutrophil count (neutrophilia), can indicate an active infection and provide important information for the healthcare provider when evaluating the wound.
While hematocrit, platelet count, and creatinine level are essential laboratory values to assess the client's overall condition, they may not provide specific information regarding the presence of infection or purulent drainage at the wound site.
Correct Answer is C
Explanation
A) Incorrect- The left lateral position might not provide enough lung expansion for a client in respiratory distress.
B) Incorrect- Reverse Trendelenburg (head of bed elevated, foot of bed lowered) might not provide enough lung expansion and could exacerbate respiratory distress.
C) Correct- The High-Fowler's position, where the client is sitting upright at a 90-degree angle or as upright as tolerated, helps to improve lung expansion, reduce pressure on the diaphragm, and promote optimal oxygenation. This position is commonly used for clients with respiratory distress.
D) Incorrect- The supine position may worsen pulmonary congestion and compromise lung expansion in clients with pulmonary edema.
