Question 1
Which of the following describes the primary pathophysiology of Lyme disease?
A) An autoimmune attack on the acetylcholine receptors at the neuromuscular junction.
B) A viral infection of the central nervous system transmitted by respiratory droplets.
C) A systemic infection resulting from the bite of an infected deer tick carrying Borrelia
burgdorferi.
D) A chronic degeneration of the myelin sheath in the peripheral nervous system.
E) A fungal infection acquired through contact with contaminated soil in wooded areas.
Correct Answer: C) A systemic infection resulting from the bite of an infected deer tick
carrying Borrelia burgdorferi.
Rationale: Lyme disease is a multi-system inflammatory disease caused by the spirochete
Borrelia burgdorferi. It is transmitted to humans through the bite of infected black-legged
ticks (deer ticks). The disease progresses in stages if not treated early, affecting the skin,
joints, heart, and nervous system.
Question 2
A patient presents with a circular, "bullseye" rash and flu-like symptoms. The nurse recognizes
these as hallmark signs of which stage of Lyme disease?
A) Stage II Early Disseminated
B) Stage III Chronic Persistent
C) Localized Stage I
D) Post-Lyme Syndrome
E) Latent Stage
Correct Answer: C) Localized Stage I
Rationale: Stage I (Localized) occurs 3 to 30 days after the tick bite. The characteristic
clinical finding is Erythema Migrans (EM), commonly known as a "bullseye" lesion. This is
often accompanied by systemic symptoms such as fever, chills, fatigue, and muscle/joint
stiffness.

Question 3
Which antibiotic is considered the first-line treatment for a patient in Stage I of Lyme disease
who is NOT allergic to penicillin?
A) Ceftriaxone
B) Gentamicin
C) Amoxicillin or Doxycycline
D) Vancomycin
E) Ciprofloxacin
Correct Answer: C) Amoxicillin or Doxycycline
Rationale: For localized Stage I Lyme disease, oral antibiotics are the standard of care.
Doxycycline or Amoxicillin are typically prescribed for 14 to 21 days. If the patient is
allergic to penicillin, Erythromycin may be used as an alternative.
Question 4
If Stage I Lyme disease is left untreated, how long does it typically take for the initial symptoms
to disappear?
A) 24 hours
B) 1 week
C) 4-5 weeks
D) 6 months
E) They never disappear without surgery
Correct Answer: C) 4-5 weeks
Rationale: Even without antibiotic treatment, the initial rash and flu-like symptoms of Stage
I may resolve on their own within 4 to 5 weeks. However, this does not mean the infection is
gone; the spirochete remains in the body and can progress to more severe disseminated
stages.
Question 5
A patient is admitted 10 weeks after a tick bite with new-onset dysrhythmias and facial paralysis.
The nurse recognizes this as:
A) Localized Stage I Lyme Disease
, 3
B) Stage II Early Disseminated Lyme Disease
C) Stage III Chronic Persistent Lyme Disease
D) Myasthenia Gravis
E) Multiple Sclerosis
Correct Answer: B) Stage II Early Disseminated Lyme Disease
Rationale: Stage II occurs 2 to 12 weeks after the bite. The infection has spread through the
bloodstream to other organs. Clinical manifestations include "Lyme carditis"
(dysrhythmias, palpitations), neurological issues (meningitis, Bell’s palsy/facial paralysis),
and peripheral neuritis.
Question 6
Which antibiotic regimen is typically required for a patient in Stage II (disseminated) Lyme
disease?
A) A single dose of oral Amoxicillin
B) IV Ceftriaxone for at least 30 days
C) Oral Doxycycline for 3 days
D) Topical antibiotic ointment to the bite site
E) IV Atropine for 14 days
Correct Answer: B) IV Ceftriaxone for at least 30 days
Rationale: Once Lyme disease reaches the disseminated stage (Stage II or III) and involves
the heart or central nervous system, aggressive therapy is needed. IV antibiotics like
Ceftriaxone or Cefotaxime are administered for a minimum of 30 days to ensure the
spirochete is eradicated from these sensitive tissues.
Question 7
A patient presents with chronic arthritis and memory problems years after an untreated tick bite.
This is characteristic of:
A) Stage I Lyme Disease
B) Stage II Lyme Disease
C) Stage III Chronic Persistent Lyme Disease
, 4
D) Osteoarthritis
E) Relapsing-Remitting MS
Correct Answer: C) Stage III Chronic Persistent Lyme Disease
Rationale: Stage III occurs months to years after the initial infection. Chronic complications
include persistent arthritis (often the first and only symptom in some), profound fatigue,
and cognitive impairments ("brain fog" or memory issues). At this stage, damage to joints
and the nervous system may be permanent.
Question 8
When educating a community group on Lyme disease prevention, which instruction should the
nurse emphasize?
A) "Wear dark-colored clothing to hide ticks."
B) "Walk through the tall grass at the edge of trails."
/C) "Walk in the center of trails and avoid heavily wooded areas."
D) "Wait until you feel a bite before applying repellent."
E) "Check your pets for ticks once every month."
Correct Answer: C) Walk in the center of trails and avoid heavily wooded areas.
Rationale: Ticks typically wait on the tips of grasses and shrubs. By staying in the center of
the trail and avoiding dense woods/tall grass, individuals minimize physical contact with
the environment where ticks reside. Protective clothing and repellent are secondary lines of
defense.
Question 9
What is the correct technique for removing a tick that is attached to the skin?
A) Burn it off with a match.
B) Smother it with petroleum jelly.
C) Remove it with tweezers or fingers covered with tissue/gloves.
D) Twist the tick counter-clockwise until it releases.
E) Wait for the tick to fall off naturally after it finishes feeding.
Correct Answer: C) remove tick with tweezers or fingers covered with tissues or gloves
Rationale: The goal of tick removal is to pull the tick out steadily without squeezing the
