Dopamine 5 mcg/kg/minute IV is prescribed for a client who weighs 132 pounds. The pharmacy dispenses a 500 mL IV solution of 0.9% normal saline with dopamine 1600 mg. The nurse should program the infusion pump to deliver how many ml/hour? (Enter numeric value only. If rounding is required, round to the nearest tenth)

Answer and Explanation

The Correct Answer is ["5.6"]

Convert pounds to kg 1kg= 2.2 pounds 132pounds= 132/2.2=60kg

Desired dose per minute= 5 mcg/kg= 560=300mcg/min Desired dose per hour= 300mcg60mins= 18000mcg Available dose= 1600mg/500ml

1mg=1000mcg

Available dose = 1600000mcg/500ml Infusion rate:

1600000mcg=500ml 18000mcg=18000500/1600000

= 5.625 mL/hour

Rounded to the nearest tenth: 5.6 ml/hour

Correct Answer is C

Explanation

A. Blood alcohol level of 0.09% (90 mmol/L): Although an elevated blood alcohol level could contribute to slurred speech and unsteady gait, the client's clinical presentation is more consistent with lithium toxicity rather than alcohol intoxication. However, it's important to assess for recent alcohol consumption and potential interactions with medications.

B. Six hours of sleep in the past three days: Sleep disturbances are common in bipolar disorder, but in this scenario, the more concerning issue is the potential lithium toxicity, as indicated by the client's symptoms.

C. Serum lithium level of 1.6 mEq/L (1.6 mmol/L): Correct! A serum lithium level above the therapeutic range (greater than 1.2 mEq/L) can lead to adverse effects such as slurred speech, ataxia, and tremors. This finding indicates lithium toxicity and requires immediate intervention.

D. Weight loss of 10 pounds (4.5 kg) in past month: Weight changes can be a concern in bipolar disorder, but in this case, the symptoms are more suggestive of lithium toxicity rather than related to weight loss

A. An adult client with a rectal tube draining clear, pale red liquid drainage. B. An older client with dark red drainage on a postoperative dressing, but no drainage in the Hemovac. C. An adult client with no postoperative drainage in the Jackson-Pratt drain with the bulb compressed. D. An older client with a distended abdomen and no drainage from the nasogastric tube.

Correct Answer is C

Explanation

A. The presence of clear, pale red liquid drainage from the rectal tube suggests possible bleeding or other issues that need prompt assessment, making this client a priority.

B. Dark red drainage on a postoperative dressing could indicate bleeding, which requires immediate attention to assess the extent of bleeding and intervene accordingly.

C. Clients with compressed Jackson-Pratt drains may not have adequate drainage, potentially leading to complications such as hematoma or infection if the drain becomes obstructed.

However, since the bulb is compressed, indicating no active drainage, this client can be assessed later.

D. A distended abdomen with no drainage from the nasogastric tube could indicate a bowel obstruction or other gastrointestinal issue requiring urgent assessment, making this client a priority for assessment.
