Category: Community Health Nursing — Comprehensive Review
1 A client presents at a community-based clinic with complaints of shortness of breath,
headache, dizziness, and nausea. During the assessment, the nurse learns that the
client is a migrant worker who often uses a gasoline-powered pressure washer to
clean equipment and farm buildings. Which type of poisoning is the most likely
etiology of this client's symptoms?
A Asbestos
B Silica dust
C Histoplasmosis
D Carbon monoxide
Why D is correct: Carbon monoxide poisoning is caused by inhalation of exhaust fumes
from gasoline-powered equipment. Symptoms include headache, dizziness, nausea, and
shortness of breath. Migrant workers using pressure washers in enclosed or poorly
ventilated spaces are at high risk.
A — Asbestos causes lung disease with prolonged exposure.
B — Silica dust causes silicosis, a chronic lung disease.
C — Histoplasmosis is a fungal infection from bird droppings.
,2 The nurse is conducting a process evaluation of a prevention education program
for older adults who are at risk for substance abuse. Which data source provides the
information the nurse needs to conduct this process evaluation?
A Client's score on an alcohol screening instrument
B Results of a urine drug and alcohol screen
C Most recent community census data
D Documentation of client education in the nursing record
Why D is correct: Process evaluation measures how the program was implemented and
delivered. Documentation of client education in the nursing record provides evidence that
the educational intervention was actually provided, which is a key process measure.
A — Screening scores are outcome measures.
B — Drug screen results are outcome measures.
C — Census data is community assessment data.
, 3 A 17-year-old unmarried, pregnant client with drug addiction is a high school
dropout, homeless, and has a history of past abuse arrives at the clinic for her first
prenatal visit. Which findings should the nurse document as health risk factors for
the client? (Select all that apply)
A Age
B School dropout
C Drug addiction
D History of abuse
E Pregnancy
F Homelessness
G Unmarried
Why A, C, D, E, F are correct: Age (adolescent pregnancy), drug addiction, history of abuse,
pregnancy, and homelessness are all documented health risk factors. School dropout and
unmarried status are social factors but not typically documented as primary health risk
factors.
B — School dropout is a social factor.
G — Unmarried status is a social factor.
