Question 1 of 5

The healthcare provider (HCP) prescribes dopamine 2 mcg/kg/min IV for client who weighs 60 kg. The IV bag contains 'Dopamine 400 mg in dextrose 5% in water (DW) 500 mL.' The nurse should program the infusion pump to deliver how many mL/hour? (Enter numerical value only.)

Correct Answer: A

Rationale: Calculation: 2 mcg/kg/min × 60 kg × 60 min/hour = 7200 mcg/hour. 7200 mcg/hour / 1000 = 7.2 mg/hour. Concentration = 400 mg / 500 mL = 0.8 mg/mL. Infusion rate = 7.2 mg/hour / 0.8 mg/mL = 9 mL/hour.

Question 2 of 5

A pH level of ________ and bicarbonate (HCO3-) level of ________ indicate a resolution of ketoacidosis.

Correct Answer: C

Rationale: A pH of 7.38 and bicarbonate of 24 mEq/L are within normal ranges, indicating resolution of ketoacidosis.

Question 3 of 5

A client admitted to the intensive care unit (ICU) with acute respiratory distress syndrome (ARDS) is intubated and placed on assist-control mechanical ventilation. When suctioning pulmonary secretions from the endotracheal tube (ETT) using a closed suction system, which action should the nurse implement to ensure that the client receives adequate oxygenation?

Correct Answer: B

Rationale: Pre-oxygenating by delivering additional breaths via the ventilator prevents hypoxia during suctioning, ensuring adequate oxygenation.

Question 4 of 5

A client who is admitted to the emergency department (ED) following a motorcycle collision is having difficulty breathing. While assessing the client's chest and lungs, the nurse notes that there are no breath sounds over the left lung fields. Which action(s) should the nurse implement? Select all that apply.

Correct Answer: A,B

Rationale: High-flow oxygen improves oxygenation in suspected pneumothorax or hemothorax. Obtaining a chest tube insertion kit prepares for definitive treatment.

Question 5 of 5

An adult who fell 20 feet (6 meters) from a tree is admitted to the intermediate intensive care unit with a fractured femur. When the cardiac monitor alarms, the nurse finds the client has no palpable carotid pulse and no spontaneous respiration, however, the cardiac monitor displays a sinus rhythm. Which intervention should the nurse implement?

Correct Answer: B

Rationale: No pulse and respirations with a sinus rhythm indicate pulseless electrical activity (PE
A). Immediate chest compressions are essential to maintain perfusion.
