Patients in shock receive fresh frozen plasma to replace which one of the following?

Red blood cells

Clotting factors

Platelets

White blood cells

Answer and Explanation

The Correct Answer is B

Fresh frozen plasma (FFP) is a blood product that contains various clotting factors, including factors II, V, VII, VIII, IX, X, XI, and XIII. These clotting factors are essential for the normal coagulation process. In patients with shock, coagulation abnormalities can occur, and administration of FFP can help replenish the deficient clotting factors and restore proper coagulation function.
The other options mentioned are not the primary components replaced by fresh frozen plasma:
A. Red blood cells are in (option A) is incorrect because Red blood cells carry oxygen and are typically replaced by packed red blood cell transfusions in cases of significant blood loss or anemia. Fresh frozen plasma does not contain a significant amount of red blood cells.
C. Platelets in (option C) is incorrect because: Platelets play a role in blood clotting and are typically replaced by platelet transfusions in cases of thrombocytopenia or platelet dysfunction. Fresh frozen plasma may contain a small number of platelets but is not the primary source for platelet replacement.
D. White blood cells in (option D) is incorrect because White blood cells are part of the immune system and are not typically replaced using fresh frozen plasma. Fresh frozen plasma does not contain a significant amount of white blood cells.
Therefore, fresh frozen plasma is primarily administered to patients in shock to replace clotting factors and help restore proper coagulation function.

Correct Answer is A

Explanation

Premature ventricular contractions (PVCs) are abnormal heart rhythms originating from the ventricles. They can be triggered by various factors, including irritation or stimulation of the airway during suctioning.
In this situation, the priority is to ensure adequate oxygenation and ventilation for the patient. Stopping the suctioning procedure and providing ventilatory support with 100% oxygen helps maintain oxygen levels and minimizes further cardiac dysrhythmias.
B. Check the patient's potassium level in (option B) is incorrect because While electrolyte imbalances, including low potassium levels (hypokalemia), can contribute to cardiac dysrhythmias, checking the potassium level is not the immediate priority when PVCs occur during suctioning.
C. Give prescribed PRN antidysrhythmic medications in (option C) is incorrect because: Administering antidysrhythmic medications without further assessment or evaluation may not be appropriate in this situation.
D. Decrease the suction pressure to 80 mm Hg in (option D) is incorrect because: While adjusting suction pressure may help prevent further irritation, it is not the initial priority when PVCs are present during suctioning.
E. Documenting the dysrhythmia in the patient's chart in (option E) is incorrect because: Documentation is important but should not be the initial action when a patient experiences PVCs during suctioning. Patient safety and immediate intervention take precedence.
Therefore, when PVCs occur during suctioning, the nurse should stop the procedure, provide ventilatory support with 100% oxygen, and assess the patient's response to intervention.

Correct Answer is ["9000"]

Explanation

4 mL × body weight in kg × percentage of burn = total fluid volume for the first 24 hours Then, divide the total fluid volume by 2 to determine the fluid volume for the first 8 hours.

In this case, the patient weighs 90 kg and has a 50% burn injury.

4 mL × 90 kg × 50% = 18,000 mL (total fluid volume for 24 hours)

18,000 mL / 2 = 9,000 mL (fluid volume for the first 8 hours)

Therefore, the nurse would infuse the intravenous fluid resuscitation at a rate of 9,000 mL over the first 8 hours.
