NU 136 EXAM 300 ACTUAL QUESTIONS AND CORRECT
ANSWERS WITH RATIONALE LATEST 2026-2027 ALREADY
GRADED A+
1. A patient reports fatigue and headache but states, "I'm probably just tired." This
is an example of which stage of illness?
A) Acceptance
B) Convalescence
C) Transition
D) Recovery
Answer: C) Transition
Rationale: The transition stage, also known as the denial stage, occurs when a
patient does not acknowledge the severity of symptoms. In this case, the patient
attributes fatigue and headache to being tired, which is a common response in the
denial phase of illness. Acceptance involves acknowledging the diagnosis;
convalescence is recovery after illness; recovery is the final stage of regaining
health.
2. A patient's heart rate increases, and pupils dilate after receiving unexpected
diagnostic results. This physiological response is characteristic of which stage of
the General Adaptation Syndrome (GAS)?
A) Resistance stage
B) Exhaustion stage
C) Alarm stage
D) Recovery stage
Answer: C) Alarm stage
Rationale: The alarm stage is the body's immediate "fight or flight" response to a
stressor. This response triggers the sympathetic nervous system, leading to
increased heart rate, pupil dilation, and a release of stress hormones. The resistance
stage is when the body attempts to adapt to the stressor, and the exhaustion stage
occurs after prolonged stress exposure, leading to fatigue and decreased immune
function.
3. What is a sign that a patient has entered the exhaustion stage of the General
Adaptation Syndrome?
A) Increased energy and alertness
,B) Frequent infections and extreme fatigue
C) Normal vital signs
D) Pupil dilation and increased heart rate
Answer: B) Frequent infections and extreme fatigue
Rationale: During the exhaustion stage, the body's resources are depleted after
prolonged exposure to stress. This results in extreme fatigue, decreased immune
function, and a higher susceptibility to infections. The alarm stage presents with
pupil dilation and increased heart rate, while the resistance stage involves the body
trying to maintain homeostasis.
4. A patient uses exercise and journaling to manage stress. This behavior is best
described as:
A) A defense mechanism
B) Maladaptive behavior
C) A coping mechanism
D) Emotional suppression
Answer: C) A coping mechanism
Rationale: Coping mechanisms are active, adaptive strategies an individual uses to
manage stress. Exercise and journaling are positive actions that help to reduce
stress and promote well-being. In contrast, defense mechanisms are often
unconscious psychological strategies, and maladaptive behaviors are harmful
coping methods.
5. A patient refuses to acknowledge a serious diagnosis despite clear evidence.
What defense mechanism is the patient using?
A) Acceptance
B) Projection
C) Denial
D) Regression
Answer: C) Denial
Rationale: Denial is a defense mechanism where a person refuses to accept reality
or facts, particularly when they are painful or distressing. By not acknowledging
the diagnosis, the patient protects themselves from the immediate emotional
impact. Projection involves attributing one's own feelings to others, and regression
involves reverting to an earlier developmental stage.
6. Which nursing intervention best supports a patient who is in the acceptance
stage of an illness?
A) Providing detailed medical terminology to help them understand their condition
B) Encouraging adaptive coping strategies and providing emotional support
,C) Avoiding discussions about their feelings to prevent upset
D) Limiting their participation in care decisions to reduce their anxiety
Answer: B) Encouraging adaptive coping strategies and providing emotional
support
Rationale: In the acceptance stage, the patient has acknowledged their condition
but may still need support to adjust. Encouraging adaptive coping strategies helps
them actively participate in their care and maintain a positive outlook. Providing
emotional support validates their feelings and helps them navigate their illness.
Using complex medical terminology can cause confusion, and limiting
participation may hinder their recovery.
7. A restaurant worker with Hepatitis A does not wash their hands after using the
restroom. What link in the chain of infection does this represent?
A) Reservoir
B) Portal of exit
C) Mode of transmission
D) Susceptible host
Answer: C) Mode of transmission
Rationale: The mode of transmission is the method by which the pathogen moves
from the reservoir to a susceptible host. In this case, the pathogen is transmitted via
the fecal-oral route through contaminated hands. The reservoir is the infected
worker, and the portal of exit is the gastrointestinal tract.
8. What does Hepatitis A represent in the chain of infection?
A) Reservoir
B) Portal of entry
C) Causative agent
D) Susceptible host
Answer: C) Causative agent
Rationale: The causative agent is the microorganism that causes the disease, in this
case, the Hepatitis A virus. The reservoir is the environment where the
microorganism lives (the infected person), and the susceptible host is the person
who can become infected.
9. In the context of infection, how is the infected restaurant worker best identified?
A) Vector
B) Reservoir
C) Portal of exit
D) Host defense
Answer: B) Reservoir
, Rationale: The reservoir is any person, animal, plant, soil, or substance in which an
infectious agent normally lives and multiplies. The infected restaurant worker
serves as the host where the Hepatitis A virus lives and multiplies, making him the
reservoir. A vector is an organism that transmits a disease without being affected.
10. Customers who consume contaminated food are considered what in the chain
of infection?
A) Reservoirs
B) Vectors
C) Susceptible hosts
D) Causative agents
Answer: C) Susceptible hosts
Rationale: A susceptible host is an individual who is at risk for developing an
infection. Customers who consume contaminated food are susceptible to infection
by the Hepatitis A virus. They are not yet infected, so they are not the reservoir,
nor are they vectors or the causative agent.
11. Which nursing action is most effective for breaking the chain of infection?
A) Wearing gloves
B) Administering antibiotics
C) Performing hand hygiene
D) Placing patients in isolation
Answer: C) Performing hand hygiene
Rationale: Hand hygiene is considered the single most important and effective
method for preventing the spread of infection. It breaks the chain by removing
pathogens from the hands, preventing their transmission to others. While wearing
gloves and using isolation are important, they are not as universally effective as
regular and thorough handwashing.
12. Why does the body develop a fever during an infection?
A) To increase oxygen demand
B) To slow the immune response
C) To reduce pathogen growth
D) To stimulate pain receptors
Answer: C) To reduce pathogen growth
Rationale: Fever is a second-line defense mechanism. The elevated body
temperature creates an environment that is less favorable for bacterial and viral
replication, helping to slow the growth of pathogens. It also enhances the immune
response by increasing the activity of white blood cells.
