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.

Answer and Explanation

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 C

Explanation

A. Lymphedema involves fluid accumulation in tissues, not fluid loss, so the client is not at risk for deficient fluid volume.
B. While health maintenance may be affected, it is not the immediate priority.
C. Lymphedema causes stagnant lymph fluid, which creates a fertile environment for bacterial growth, making infection a primary concern.
D. Body image may be affected long-term, but preventing infection takes precedence in acute care planning.

A. Irregular B. Slow C. Not palpable D. Bounding

Correct Answer is A

Explanation

A. Atrial fibrillation causes disorganized atrial electrical activity, leading to an irregularly irregular pulse rhythm, which is a hallmark finding.
B. The heart rate in atrial fibrillation can be fast, slow, or normal depending on ventricular response, but the defining feature is irregularity—not slowness.
C. The pulse remains palpable, though some beats may be weak or missed due to variable ventricular filling.
D. A bounding pulse is not characteristic of atrial fibrillation and is more commonly associated with conditions like fever, anemia, or hyperthyroidism.
