Heparin 7,000 units is ordered. Heparin 5,000 units per ml is available. How many milliliters (ml) should the nurse administer?
(Do not round)
The Correct Answer is ["1.4"]
We know that 7,000 units is equivalent to 5,000 units per ml. So, we can set up the proportion:
7,000 units / 5,000 units per ml = x ml / 1 ml x = 7,000 / 5,000
x = 1.4
Therefore, the nurse should administer 1.4 milliliters (ml) of heparin.

Correct Answer is B
Explanation
According to the given information, Aydan's insulin lispro (Humalog) dosage is 1 unit per 50 grams of carbohydrates eaten. As Aydan has just consumed 150 grams of carbs for lunch, we can calculate the insulin dose as follows:
Insulin dose = Carbohydrates eaten / Insulin-to-carbohydrate ratio Insulin dose = 150 grams / 50 grams/unit
Insulin dose = 3 units
Therefore, the nurse should prepare to administer 3 units of Aydan's prescribed rapid-acting insulin (Insulin lispro) to cover the carbohydrates he consumed for lunch. The long-acting insulin (Glargine) is typically given at bedtime to provide a basal insulin level and is not directly related to meal coverage.
Correct Answer is A
Explanation
The patient's vital signs indicate signs of septic shock, including low blood pressure (70/46 mm Hg), tachycardia (136 beats/min), and tachypnea (32 breaths/min). The patient also has a high temperature of 104°F, indicating a fever. These findings suggest a systemic response to an infection that is leading to inadequate tissue perfusion.The initial treatment for septic shock includes fluid resuscitation to improve blood pressure and tissue perfusion. A fluid bolus of 0.9% Sodium Chloride (normal saline) is commonly used to restore intravascular volume in septic shock. It helps to increase blood pressure, improve organ perfusion, and stabilize the patient's condition.
The other interventions, such as administering Pantoprazole (Protonix) for gastrointestinal protection, giving Acetaminophen (Tylenol) for fever control, or administering rapid-acting insulin per sliding scale for hyperglycemia, are important aspects of care but should be implemented after the initial fluid resuscitation. The priority at this moment is to address the patient's hypotension and inadequate tissue perfusion through the administration of fluid bolus.
