The nurse is conducting intake interviews of children at a city clinic. Which child is most susceptible to contracting lead poisoning?
An 8-year-old who lives in a housing project.
A 2-year-old who plays on aging outdoor playground equipment.
An adolescent who works part-time in a paint factory.
A 10-year-old who has Type 1 diabetes mellitus.
The Correct Answer is B
Choice A reason: While living in older housing projects can pose a risk, the age of the child and their behaviors, such as hand-to-mouth activities, make younger children more susceptible.
Choice B reason: A 2-year-old is at the highest risk due to their developmental stage, which includes frequent hand-to-mouth activity and the likelihood of playing in soil or dust that may be contaminated with lead.
Choice C reason: Adolescents working in a paint factory may be exposed to lead; however, they are less likely to engage in hand-to-mouth behaviors that lead to ingestion, which is the primary route of lead poisoning in children.
Choice D reason: A 10-year-old with Type 1 diabetes mellitus does not have an increased risk of lead poisoning based on their condition alone.

Correct Answer is ["2.4"]
Explanation
Step 1: Convert the weight from pounds to kilograms. We know that 1 kg = 2.2 lbs. So, the weight in kg is:
175 lbs ÷ 2.2 = 79.55 kg
Step 2: Calculate the total units of heparin needed. The prescription is for 3 units/kg, so:
3 units/kg × 79.55 kg = 238.65 units
Step 3: Calculate the volume of heparin to administer. The vial is labeled as "100 units/mL", so:
238.65 units ÷ 100 units/mL = 2.39 mL
So, the nurse should administer approximately 2.4 mL of heparin (rounded to the nearest tenth).
Correct Answer is A
Explanation
Choice A reason: Engaging in non-threatening conversations can help the client feel more comfortable and may encourage communication, which is crucial for clients who are withdrawn due to depression.
Choice B reason: Family visits can be supportive, but the client's withdrawal suggests a need for more direct intervention to encourage communication.
Choice C reason: Scheduling a conference with a social worker is important, but it is not the most immediate intervention for a withdrawn client.
Choice D reason: Group activities may be overwhelming for a client who is noncommunicative and may not be the most suitable initial approach.
