A child who weighs 65 pounds is to receive heparin 75 units/kg IV bolus. How many units will the nurse administer? (Enter the numeric value only. If rounding is required, round to the nearest whole number.)
The Correct Answer is ["2216"]
Step 1: Convert weight to kilograms
Weight (kg) = 65 ÷ 2.2 ≈ 29.55 kg
Step 2: Calculate dose in units
Dose (units) = Weight × Dose per kg
= 29.55 × 75
≈ 2216.25 units
Step 3: Round to the nearest whole number
≈ 2,216 units

Correct Answer is C
Explanation
A. Nipple stimulation during pregnancy, especially in the third trimester, can trigger uterine contractions and may increase the risk of preterm labor. It is not recommended as a routine measure to prepare for breastfeeding.
B. While a supportive bra can improve comfort, it does not address the client’s concerns about breast changes or nipple discharge, and it is not necessary for evaluation purposes.
C. This is the correct action. The "lumpy places" likely represent normal breast tissue changes, such as lobular development, and the yellowish fluid is colostrum, a normal early breast secretion. Reassuring the client that these changes are typical in late pregnancy and that they will be assessed at her upcoming prenatal visit helps alleviate anxiety while avoiding unnecessary interventions.
D. There is no urgent need for an earlier appointment, as the symptoms described are expected physiologic changes. Rescheduling would create unnecessary burden and anxiety.
Correct Answer is ["42"]
Explanation
Step 1: Identify the formula
gtt/min = (Total volume × Drop factor) ÷ Time (in minutes)
Step 2: Insert values
Total volume = 1000 mL, Drop factor = 10 gtt/mL, Time = 4 hr × 60 min/hr = 240 min
gtt/min = (1000 × 10) ÷ 240
Step 3: Calculate
= 10,000 ÷ 240
≈ 41.67
Step 4: Round to the nearest whole number
≈ 42 gtt/min
