The patient has an order for clindamycin 600 mg IV every 12 hours.

Clindamycin from the pharmacy comes as 600 mg in 50 ml. It is to run over 20 minutes.

The nurse should set the pump to deliver how many ml/hr?

Answer and Explanation

The Correct Answer is ["150"]

Step 1 is: 600 mg of Clindamycin in 50 mL is to run over 20 minutes.

Step 2 is: To find mL/hr, convert the minutes to hours by dividing 60 min by 20 min. 60 min ÷ 20 min = 3.

Step 3 is: Multiply the total volume of 50 mL by the conversion factor of 3. 50 mL × 3 = 150 mL. Final calculated answer is 150 mL/hr. *.

Correct Answer is ["5"]

Explanation

The patient has an order for heparin 100 units over one hour. Heparin from the pharmacy comes as 10,000 units in 500 ml. The nurse should set the pump to deliver how many ml/hr?.

Step 1: Calculate the concentration of the heparin solution. 10,000 units ÷ 500 mL = 20 units/mL.

Step 2: Determine the volume of solution required to deliver 100 units. 100 units ÷ (20 units/mL) = 5 mL.

Step 3: The infusion is to be delivered over one hour. 5 mL ÷ 1 hour = 5 mL/hr. The nurse should set the pump to deliver 5 mL/hr.

A. Iron. B. PRBC. C. Fresh frozen plasma. D. Albumin.

Correct Answer is C

Explanation

Choice A rationale

Iron is a crucial component of hemoglobin and is essential for erythropoiesis. However, a significant burn injury primarily causes massive fluid shifts and plasma loss from the intravascular space into the interstitial spaces, leading to hypovolemia and hemoconcentration. Iron supplementation would not address the immediate, life-threatening fluid and protein depletion that characterizes the initial phase of a major burn.

Choice B rationale

PRBCs, or packed red blood cells, are used to restore oxygen-carrying capacity in the event of significant blood loss or anemia. While a burn patient may eventually become anemic, the immediate and most critical need following a major burn is the replacement of lost plasma volume and proteins, which is not effectively addressed by PRBCs alone.

Choice C rationale

A severe burn causes a substantial loss of plasma proteins, including albumin, globulins, and clotting factors, from the circulation due to increased capillary permeability. Fresh frozen plasma (FFP) is rich in these proteins and clotting factors, making it the most appropriate choice to restore intravascular volume, oncotic pressure, and hemostasis, thereby combating hypovolemic shock.

Choice D rationale

Albumin is a major plasma protein and is effective for increasing oncotic pressure and drawing fluid back into the vasculature. However, fresh frozen plasma (FFP) is a more comprehensive choice as it contains albumin along with other essential plasma proteins, coagulation factors, and immunoglobulins, which are all depleted following a severe burn injury
