What signs and symptoms would a patient with stage I Lyme disease have?
a. Signs of neurological disorders
b. Enlarged and inflamed joints
c. Arthralgias
d. Flu-like symptoms
d. Flu-like symptoms
When developing a plan of care for a patient with stage I Lyme disease, which of the following
would you want to include?
a. No treatment without symptoms
b. Three-week course of oral antibiotics
c. Hospitalization for intravenous antibiotics
d. None of the above
b. Three-week course of oral antibiotics
In stage I Lyme disease, a three-week course of oral antibiotics is begun. In later stages the
patient may require intravenous antibiotics. Requiring outwardly visible symptoms for treatment
is an inappropriate response for patients with Lyme disease.
You are caring for a patient with frostbite on the hand. What assessment finding do you expect to
find on the hand?
a. Edema in the nail beds with fiery red skin
b. The hand is pink and edematous.
c. Erythematous rash and black fingertips
d. Decreased sensitivity to touch with white color to the skin
d. Decreased sensitivity to touch with white color to the skin
,The hand would have decreased or nonexistent sensitivity to touch with a white or blue color to
the skin. The skin may also be hard and cold. Tissue edema, blisters and flushing of the skin may
occur as the hand begins to thaw.
Which of the following would be prescribed for a patient with frostbite on the toes?
a. Continuous, rapid rewarming of the toes in warm water until flushing returns
b. Continuous, rapid rewarming of the toes in warm water for 15 to 20 minutes
c. Continuous, rapid rewarming of the toes in warm water once flushing returns
d. Continuous, rapid rewarming of the toes in cold water for 45 minutes
a. Continuous, rapid rewarming of the toes in warm water until flushing returns
The nurse should prepare for orders for continuous, rapid rewarming of the toes in warm water
until flushing returns. Slow rewarming of the affected area can lead to increased cellular damage,
so it is avoided. Rewarming can lead to pain, so analgesics should be prescribed.
What is the anticipated therapeutic effect of an escharotomy?
a. Bleeding from the site
b. Formation of granulation
tissue c, Decreasing
edema formation d.
Return of distal pulses
d. Return of distal pulses
The purpose of escharotomy is to relieve compartment syndrome and facilitate the return of
distal pulses. Bleeding is considered to be a complication, not a therapeutic technique. Direct
pressure to the site will help to decreasing bleeding.
Your patient has sustained a burn from cutaneous exposure to lye. The patient received one hour
of irrigation at the site of the injury prior to coming to the emergency department. When you
assess the site what, finding tells you that the burn continues?
a. Eschar
b.Liquefaction necrosis
c. Cherry red, firm tissue
d. Intact blisters
,b.Liquefaction necrosis
Liquefaction necrosis is an indication that the chemical is still burning the patient. Exposure to
acids or heat causes thick, leathery eschars to form. Thermal injury can lead to cherry red, firm
tissue. Partial-thickness thermal injury leads to intact blisters.
Which of the following would you expect to see with second- and third-degree burns in the
emergent phase?
a. Decreased heart rate
b. Increased blood pressure
c. Elevated hematocrit levels
d. Increased urinary output
c. Elevated hematocrit levels
One would expect to find elevated hematocrit levels in a patient in the emergent phase of second-
or third-degree burns. 48 to 72 hours after injury, the emergent phase ends with the restoration of
capillary permeability. Hemoconcentration from large fluid shifts leads to increased hematocrit.
You have delegated care of a patient in restraints to a nursing assistant. How often should the
nursing assistant inspect skin integrity for this patient?

b. Every 2 hours
c. Every 3 hours
d. Every 4 hours
