The physician orders furosemide 67 mg IV push STAT for edema. Your vial of furosemide contains 40 mg in 4 ml. How many milliliters will you administer?
The Correct Answer is ["6.7"]
Step 1: Identify the ordered dose.
Ordered dose = 67 mg
Step 2: Identify the available concentration.
40 mg in 4 mL = 10 mg per 1 mL
Step 3: Use the formula.
mL to administer = Ordered dose ÷ Concentration
67 mg ÷ 10 mg/mL = 6.7 mL
Answer: 6.7 mL

Correct Answer is A
Explanation
Rationale:
A. Hypothermia is correct because rapid infusion of large volumes of crystalloid fluids—especially if the fluids are at room temperature or refrigerated—can lower the patient’s core body temperature. This is particularly important in patients in shock because hypothermia can exacerbate coagulopathy, impair oxygen delivery, and increase the risk of arrhythmias, all of which can worsen outcomes. In addition, critically ill patients are often already at risk for hypothermia due to exposure during resuscitation, impaired thermoregulation, or blood loss. Nursing interventions include monitoring temperature closely, using fluid warmers, applying warming blankets, and assessing for shivering.
B. Bradycardia is incorrect because fluid resuscitation for hypovolemic shock typically increases preload and cardiac output, leading to tachycardia as a compensatory mechanism. Bradycardia is not a common or expected effect of large-volume crystalloid infusion in this context, and if present, it may indicate another problem such as cardiac conduction abnormalities or medication effects.
C. Coffee ground emesis is incorrect because this indicates upper gastrointestinal bleeding, which is not a direct consequence of crystalloid fluid administration. While stress-related mucosal disease can occur in critically ill patients, coffee ground emesis is not an expected sign to monitor specifically due to fluid resuscitation.
D. Pain is incorrect because although a patient may experience discomfort at the IV site or from underlying injuries, pain is not a specific or anticipated effect of large-volume crystalloid infusion. Monitoring for pain is always appropriate, but it is not the priority sign related to this intervention.
Correct Answer is ["0.7"]
Explanation
Step 1: Identify the ordered dose.
Ordered dose = 350 mg
Step 2: Identify the concentration of the medication.
Available concentration = 500 mg per 1 mL
Step 3: Use the formula.
Amount to give (mL) = Ordered dose ÷ Concentration
350 mg ÷ 500 mg/mL = 0.7 mL
Answer: 0.7 mL per day
