D450 OA EXAM SET 1
Question 1
A community health nurse responds to a call about an unconscious individual
found in a park. Upon arrival, the nurse observes slow respiratory depression,
gurgling sounds, blue/gray skin color, inability to talk, disorientation, and
pinpoint pupils. What is the most likely cause of these signs and symptoms?
A. Hypoglycemic crisis
B. Opioid drug overdose
C. Acute myocardial infarction
D. Severe allergic reaction
Correct Answer:
B. Opioid drug overdose
Rationale: The classic triad for opioid overdose includes respiratory depression,
pinpoint pupils (miosis), and altered mental status. The gurgling sounds (often called the
"death rattle") result from decreased gag reflex and fluid accumulation. Blue/gray skin
color (cyanosis) indicates severe hypoxia from respiratory depression. These findings
are pathognomonic for opioid toxicity and require immediate administration of naloxone
(Narcan).
,Question 2
A nurse is educating community members about emergency response to opioid
overdose. What is naloxone, and what is its primary function?
A. A sedative that calms the patient during withdrawal
B. Narcan — a medication that rapidly reverses the effects of opioid overdose
C. An antibiotic that treats secondary infections from IV drug use
D. A long-acting opioid that prevents withdrawal symptoms
Correct Answer:
B. Narcan — a medication that rapidly reverses the effects of opioid overdose
Rationale: Naloxone (brand name Narcan) is a competitive opioid antagonist that
displaces opioids from mu-receptors in the brain. It rapidly reverses respiratory
depression and sedation caused by opioid overdose. It has no effect on non-opioid
substances and does not produce euphoria or respiratory depression itself, making it
safe for bystander administration.
Question 3
A bystander has just administered naloxone to a person experiencing an opioid
overdose. Which sequence of actions should the bystander follow next?
A. Place patient in prone position, administer CPR, wait 10 minutes for response
B. Lay patient on back, spray naloxone into nose, place patient on side, monitor for
response within 2–3 minutes, call 911
C. Sit patient upright, give oral naloxone, encourage walking to stimulate circulation
D. Immediately begin chest compressions regardless of breathing status
Correct Answer:
B. Lay patient on back, spray naloxone into nose, place patient on side, monitor
for response within 2–3 minutes, call 911
Rationale: The correct sequence for naloxone administration is: (1) Lay the patient
supine to ensure proper nasal spray delivery; (2) Administer intranasal spray (half in
each nostril); (3) Place in recovery (lateral) position to prevent aspiration if vomiting
occurs; (4) Monitor for response — breathing should improve within 2–3 minutes; (5)
Call 911 immediately, as naloxone's effects last 30–90 minutes while opioids may last
longer, risking re-sedation.
,Question 4
A mother is concerned because her 4-year-old child is showing jealousy toward
her newborn sibling who is breastfeeding. What is the most appropriate nursing
intervention to help the older child adjust?
A. Discourage the child from being present during breastfeeding to reduce stimulation
B. Validate the child's feelings and allow them to participate in baby care activities
C. Tell the child that jealousy is unacceptable and will result in punishment
D. Immediately stop breastfeeding to eliminate the source of jealousy
Correct Answer:
B. Validate the child's feelings and allow them to participate in baby care
activities
Rationale: Sibling jealousy is a normal developmental response to a new baby.
Validation helps the child feel heard and understood, reducing acting-out behaviors.
Involvement in age-appropriate baby care (fetching diapers, singing to baby) fosters
bonding and gives the older child a sense of importance. Excluding the child or punitive
approaches increase resentment and behavioral regression.
Question 5
A community health nurse is developing a presentation on osteoporosis
prevention for a senior center. Which recommendations should be included?
(Select all that apply)
A. Weight-bearing and strength-training exercises
B. Foods high in calcium and vitamin D
C. Prolonged bed rest to preserve bone density
D. Avoidance of all dairy products
E. Regular sun exposure without sunscreen
Correct Answers: A, B
Rationale: Osteoporosis prevention focuses on: (1) Weight-bearing exercises
(walking, jogging, resistance training) stimulate osteoblast activity and bone remodeling;
(2) Strength training improves muscle mass and balance, reducing fall risk; (3)
Calcium (1,200 mg/day for adults >50) and Vitamin D (800–1,000 IU/day) are essential
for bone mineralization. Prolonged bed rest accelerates bone loss. Dairy is a primary
calcium source. Sun exposure should be balanced with skin cancer prevention.
,A. Improved glycemic control
B. Signaling high blood sugar and insulin resistance
C. An allergic reaction to diabetic medication
D. Normal age-related skin changes
Correct Answer:
B. Signaling high blood sugar and insulin resistance
Rationale: Acanthosis nigricans presents as velvety, hyperpigmented, thickened skin
in body folds (neck, axilla, groin). It is a cutaneous marker of insulin resistance —
hyperinsulinemia stimulates keratinocyte and fibroblast proliferation through insulin-like
growth factor receptors. It is strongly associated with: Type 2 diabetes, metabolic
syndrome, obesity, and polycystic ovary syndrome. It is NOT normal aging (D) or allergy
(C). Its presence suggests need for enhanced diabetes management and evaluation for
metabolic syndrome components.
,Correct Answer:
B — B-type natriuretic peptide (BNP) level of 550 pg/mL
Table
Lab Value Reference Clinical Interpretation
Range/Expected
Total Desirable: <200 mg/dL Normal, cardioprotective
cholesterol 190
BNP 550 Normal: <100 pg/mL Elevated — indicates cardiac
wall stress/fluid overload
Hgb A1c 7% Target for DM: <7% Acceptable glycemic control
Potassium 3.7 Normal: 3.5–5.0 Normal
mEq/L
Rationale: BNP is released by cardiac ventricles in response to volume expansion
and increased wall stress. Levels >400 pg/mL strongly suggest heart failure
decompensation. A level of 550 pg/mL indicates significant fluid overload and
potential acute decompensated heart failure requiring immediate medical evaluation
for diuretic adjustment, possible hospitalization, and further cardiac workup. The other
values are within normal or target ranges and do not require urgent provider notification.
Question 76
Despite numerous instructions, an elderly patient with Parkinson's disease is
unable to administer ophthalmic medication without assistance due to hand
tremors. Which action should the nurse take?
a. Discontinue the eye medication and consult the provider for an alternative route
b. Determine if a family member is available and willing to administer the medication
c. Recommend the patient use a pill organizer for the eye drops
d. Teach the patient to stabilize their hands on a table while administering the drops
,The school nurse is assessing a group of middle school students for signs of
scoliosis and discovers a student with a noticeable unequal symmetry of the
upper and lower back. Which intervention is most important for the nurse to
implement?
a. Measure the degree of thoracic and lumbar curvature with a scoliometer
b. Ask the student about any family history of spinal deformities
c. Make a referral to have the scoliosis further evaluated
d. Notify the parents that the student cannot participate in physical education
Correct Answer:
C — Make a referral to have the scoliosis further evaluated
Table
School Nurse Role Scoliosis Screening Protocol
Screening Visual inspection, Adams forward bend test
NOT diagnostic Cannot diagnose or measure Cobb angle
Referral Required for positive screens
Follow-up Orthopedic specialist, radiographic evaluation
Rationale: School nurses perform screening, not diagnosis. A positive screen
(unequal symmetry, rib hump on forward bend) requires referral to a healthcare
provider (orthopedist) for definitive evaluation including Cobb angle measurement on
X-ray. This determines if intervention (observation, bracing, surgery) is needed.
Measuring with a scoliometer (A) may be part of screening but doesn't replace specialist
evaluation. Family history (B) is relevant but secondary to referral. Restricting PE (D) is
inappropriate without diagnosis and may harm the student's social and physical
development.
Question 75
When assessing the health of a community, which is the most important
information for the nurse to obtain?
,eldest child. Overall family tasks are identified that need to be accomplished for each
stage of family development.
Question 108: Family health can be defined as a dynamic, changing, relative state of
well-being that includes the biological, psychological, sociological, cultural, and spiritual
factors of a family system. This family health approach would best include which of the
following underlying principles? (Select all that apply)
a. Assessment of the individual's health does not determine the overall family system's
health.
b. Family functioning affects the health of family members.
c. Family system assessment specifically addresses the individual's health.
d. The individual's health affects family functioning.
e. Simultaneous assessment of individual family members and the family system as a
whole is important to family health.
Correct Answer:
b, d, e
Rationale: Family health includes the principles that family functioning affects the
health of family members, the individual's health affects family functioning, and
simultaneous assessment of individual family members and the family system as a
whole is important.
Question 109: A family nurse is working with a married couple that has decided to
remain child-free. The nurse recognizes this decision as a:
a. biological necessity.
b. contemporary family function.
c. religious belief decision.
d. threat to family survival.
Correct Answer:
b. contemporary family function.
Rationale: In contemporary times, the traditional functions of families have been
modified and new functions added. One of the traditional family functions was to
procreate to ensure the survival of the species. Many married couples are electing to be
child-free rather than to have children.
, Question 110: A nurse in community health is working with a single parent of three
children, ages 4, 6, and 8. The 6-year-old has cerebral palsy. The 4-year-old has
asthma. The maternal grandmother lives with the family and has diabetes. The nurse
understands the importance of working within the context of the existing family structure
and community resources because families are:
a. resistive to outside intervention or involvement.
b. responsible for providing/managing the care of their members.
c. unable to manage the stress of complex health needs.
d. restricted in their ability to identify interventions.
Correct Answer:
b. responsible for providing/managing the care of their members.
Rationale: Health care decisions are made within the family, the basic social unit of
society. Families are responsible for providing and managing the care of family
members. Families are significant members of health care teams because they are an
ever-present force over the lifetime of care.
Question 111: A nurse doing a family assessment asks the client, 'Have any of your
blood relatives had mental illness?' The nurse is asking this question to:
a. determine whether the family is stable.
b. assess for biological risk factors.
c. decide whether this family member needs medication.
d. demonstrate open-mindedness about mental illness.
Correct Answer:
b. assess for biological risk factors.
Rationale: Healthy People 2020 identified the following major categories: inherited
biological risk, including age-related risks, social and physical environmental risks and
behavioral risks as well as health care risks. Although single risk factors can influence
outcomes, the combined effect of several risks has greater impact.
Question 112: A parent with two school-age children has just finished a family health
assessment questionnaire. The parent asks the nurse why one of the questions asks
whether there is a neighborhood playground. The nurse's best response would be:
a. 'Don't worry about it. We are going to talk about all this anyway.'
b. 'It's important to good health to have adequate recreation resources.'
c. 'We want to be able to report any dangerous playground equipment to the city.'
