The healthcare provider prescribes dopamine 2 mcg/kg/min intravenously (IV) for client who weighs 60 kg. The IV bag contains dopamine 200 mg in dextrose 5% in water (DW) 250 mL. The nurse should program the infusion pump to deliver how many mL/hour? (Enter numerical value only.)
Answer and Explanation

The Correct Answer is ["9"]

Here are the steps you can follow to calculate the infusion pump flow rate:

Step 1: Calculate the prescribed dose in mcg/min

  1. Dose per weight: 2 mcg/kg/min * 60 kg = 120 mcg/min

Step 2: Convert the concentration in the IV bag to mcg/mL

  1. Convert mg to mcg: 200 mg * 1000 mcg/mg = 200,000 mcg
  2. Concentration: 200,000 mcg / 250 mL = 800 mcg/mL

Step 3: Calculate the flow rate in mL/min

  1. Flow rate: 120 mcg/min / 800 mcg/mL = 0.15 mL/min

Step 4: Convert the flow rate to mL/hour

  1. Hour conversion: 0.15 mL/min * 60 min/hour = 9 mL/hour

Therefore, the nurse should program the infusion pump to deliver 9 mL/hour.

Correct Answer is ["A","D"]

Explanation

Choice A rationale: Hypoxic-ischemic injury from submersion can lead to delayed cerebral edema. Monitoring is critical as the brain's inflammatory response to the initial insult often peaks several hours after the event.

Choice B rationale: Asphyxia is the initial event that occurred in the pool. By the time the child is admitted to the pediatric floor, the asphyxiation event has passed; the nurse now monitors for its aftereffects.

Choice C rationale: Near-drowning victims are more likely to experience hypotension due to myocardial depression or shifting fluid balances. Hypertension is not a typical expected complication in the immediate post-submersion recovery period.

Choice D rationale: Aspiration of water interferes with surfactant production and damages alveolar membranes, leading to pulmonary edema or ARDS. Respiratory status can deteriorate rapidly 6 to 8 hours after the initial insult.

Choice E rationale: The child was in cool water with an outdoor temperature of 64°F, making hypothermia the primary concern. Hyperthermia is not expected unless a secondary infection or a thermregulation failure occurs much later.

Choice F rationale: The head CT scan was negative for bleeding. Without a significant traumatic impact or pre-existing condition, a subdural hemorrhage is not a standard complication resulting from a submersion injury.

Correct Answer is A

Explanation

A) Correct- this can help them structure their time, reduce boredom and anxiety, and increase their sense of control and achievement. This can also foster social interaction and engagement with the staff and peers. A schedule of planned daily activities is consistent with the principles of psychosocial rehabilitation, which is an evidence-based approach for people with schizophrenia.
B) Incorrect- this may be too challenging or stressful for the client, especially if they have cognitive impairments or negative symptoms.
C) Incorrect- may expose them to unfamiliar or unpredictable situations that could trigger or worsen their psychotic symptoms.
D) Incorrect- it is not an intervention that directly addresses the client's current problem of social isolation.
