The physician orders erythromycin 1 g in 100 mL of D₅W to infuse over 30 minutes. Calculate the IV flow rate in milliliters per hour (mL/hr). Round to the nearest whole number.
The Correct Answer is ["200"]
Ordered: Erythromycin 1 g in 100 mL D₅W over 30 minutes
Goal: Calculate IV flow rate in mL/hr
Step 1: Use the formula
IV flow rate (mL/hr) = (Total volume to infuse ÷ Time in minutes) × 60
IV flow rate = (100 ÷ 30) × 60
IV flow rate = 3.33 × 60
IV flow rate = 200
Final Answer: 200 mL/hr

Correct Answer is D
Explanation
A. Fluid overload typically causes an elevated CVP due to increased blood volume.
B. Intracardiac shunts affect cardiac output and oxygenation but do not directly cause low CVP readings.
C. Left ventricular failure usually results in increased CVP because of back pressure on the right heart.
D. Hypovolemia (decreased blood volume) leads to low CVP as there is less venous return to the right atrium. This is the correct interpretation of a low CVP reading in trauma clients who may have blood loss.
Correct Answer is D
Explanation
A. While aspirin has analgesic properties, this is not the primary reason it is prescribed post-MI.
B. Aspirin can reduce fever, but its antipyretic effect is not the focus in cardiovascular care.
C. Aspirin's anti-inflammatory action is helpful in some conditions, but not the main reason for post-MI use.
D. Aspirin inhibits platelet aggregation, reducing the risk of thrombus (clot) formation in coronary arteries, which helps prevent future myocardial infarctions—making this the key therapeutic action in this context.
