RN 401: National RN Comprehensive Exit Final
Examination Prep with Detailed Rationales
Course Code: RN 401
Course Name: Comprehensive Nursing Synthesis
Topic: Critical Care Triage, Advanced Patient Isolation, Maternal-Neonatal
Complications, and Pharmacological Safety
Academic Year: 2026/2027
1. A nurse in an emergency department completes an assessment on an
adolescent client who has conduct disorder and threatened suicide to a teacher
at school. Which of the following statements should the nurse include in the
assessment?
A. "Tell me about your siblings."
B. "Tell me what kind of music you like."
C. "Tell me how often do you drink alcohol."
D. "Tell me about your school schedule."
CORRECT ANSWER: C
RATIONALE: Adolescents with conduct disorder exhibit a high incidence
of behavioral disinhibition, impulsivity, and concurrent substance abuse, which
significantly elevates their risk for executing suicide threats. The nurse must
directly evaluate substance use by asking how often the client consumes alcohol,
as acute intoxication lowers inhibitions and increases suicidal lethality. Baseline
queries about siblings, musical preferences, or school schedules do not screen for
active safety hazards or substance-related self-harm triggers.
2. A nurse is observing a client interacting with her newborn. Which of the
following actions by the client requires the nurse to intervene?
A. Holding the newborn in an en face position
B. Asking the father to change the newborn's diaper
C. Requesting the nurse to take the newborn to the nursery so she can rest
D. Viewing the newborn's actions to be uncooperative
CORRECT ANSWER: D
RATIONALE: Viewing a newborn's normal, instinctive behavioral cues
,as deliberately uncooperative indicates a structural impairment in maternal-infant
bonding and realistic parental expectations. This perception requires immediate
nursing intervention and supportive education. Conversely, maintaining an en face
position (eye-to-eye alignment) indicates positive bonding. Incorporating the
father into diaper changes fosters family-centered care, and requesting nursery
placement to manage postpartum fatigue is an acceptable self-care strategy that
does not indicate maladaptive bonding.
3. A nurse is caring for a client who is taking levothyroxine. Which of the
following findings should indicate that the medication is effective?
A. Weight loss
B. Absence of seizures
C. Decreased inflammation
D. Increased somnolence
CORRECT ANSWER: A
RATIONALE: Levothyroxine functions as a synthetic form of thyroxine
(T4), effectively accelerating the basal metabolic rate in clients with
hypothyroidism. A classic indicator of therapeutic efficacy is weight loss,
alongside improved energy levels, decreased serum TSH, and a resolution of
bradycardia and constipation. Levothyroxine does not possess anticonvulsant or
anti-inflammatory properties, making seizure control or reduced inflammation
incorrect markers of effectiveness.
4. A nurse is planning discharge teaching for cord care for the parent of a
newborn. Which of the following instructions should the nurse include?
A. Contact the provider if the cord turns black.
B. Clean the base of the cord with hydrogen peroxide daily.
C. Keep the cord dry until it falls off.
D. The cord stump will fall off automatically in five days.
CORRECT ANSWER: C
RATIONALE: Neonatal cord care focuses on keeping the umbilical cord
clean and dry to facilitate natural sloughing and prevent bacterial colonization
(omphalitis). The cord naturally shrivels, turns black, and falls off within 10 to 14
days, making a black appearance normal. Applying harsh chemical agents like
, hydrogen peroxide or isopropyl alcohol is contraindicated because it delays healing
and irritates the surrounding skin.
5. A nurse is assessing a client in the post-anesthesia care unit (PACU). Which
of the following findings indicates decreased cardiac output?
A. Shivering
B. Oliguria
C. Bradypnea
D. Constricted pupils
CORRECT ANSWER: B
RATIONALE: A reduction in cardiac output reduces systemic tissue
perfusion, forcing the kidneys to conserve fluid. This directly results in oliguria
(urine output less than 30 mL/hr). Shivering is a common physiological response to
hypothermia in the PACU. Bradypnea is typically caused by residual anesthetic or
opioid depression, and pupil constriction points to opioid effects rather than a state
of low systemic cardiac output.
6. A nurse is assisting with mass casualty triage following an explosion at a
local factory. Which of the following clients should the nurse identify as the
priority?
A. A client who has massive head trauma and fixed pupils
B. A client who has full-thickness burns to the face and trunk
C. A client with clear indications of hypovolemic shock
D. A client with an open fracture of the lower extremity
CORRECT ANSWER: C
RATIONALE: In mass casualty triage, resources are prioritized for
individuals with life-threatening injuries who have a high probability of survival if
stabilized immediately (Class I, Red Tag). A client with indications of
hypovolemic shock requires urgent fluid resuscitation and falls squarely into this
category. Massive head trauma with fixed pupils indicates an expected lethal
outcome, classifying them as Class IV (Black Tag). Face and trunk burns carry
airway risks but require intensive specialized resources, while a closed or open
extremity fracture without active hemorrhage is categorized as Class II (Yellow
Tag).
