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: While regular foot inspection is important for individuals with diabetes to prevent complications, it is typically recommended to be done daily rather than monthly.
- B: While having regular meals is part of good diabetes management, the statement does not encompass the entirety of dietary management such as carbohydrate counting or monitoring blood glucose levels.
- C: Annual eye examinations with an ophthalmologist are crucial for individuals with diabetes as they are at risk for diabetic retinopathy, which can lead to blindness if not detected and treated early.
- D: Although using salt, herbs, and spices can improve the flavor of foods, this statement does not directly relate to diabetes management and symptom control. Moreover, excessive salt intake should be avoided in diabetes due to the increased risk of hypertension.

A. Blood alcohol level of 0.09% (90 mmol/L) B. Six hours of sleep in the past three days. C. Serum lithium level of 1.6 mEq/L (1.6 mmol/L). D. Weight loss of 10 pounds (4.5 kg) in past month.

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
