A patient presents with a localized infection under the skin that
resembles a blister or pimple filled with fluid or pus. Which condition
does this describe?
a. Hematoma
b. Abscess
c. Aneurysm
d. Ecchymosis
✔️ Correct Answer: B
Rationale:
An abscess is an infection under the skin that looks like a blister or
pimple filled with fluid or pus (Option B). In dialysis patients, abscesses
are a significant concern because if needles are inserted into or near an
abscess, infection of the dialysis access or other tissues may occur.
Abscesses require prompt medical attention and should never be
cannulated. The presence of an abscess near a vascular access site is a
contraindication for dialysis treatment until the infection is resolved.
Option A is incorrect because a hematoma is a collection of blood under
the skin, not an infection. Option C is incorrect because an aneurysm is
a ballooning or bulging of a weak spot in a blood vessel. Option D is
incorrect because ecchymosis is bruising or bleeding under the skin.
,A hemodialysis patient requires access to the bloodstream for
treatment. Which of the following describes a vascular access that is
created by surgically connecting a vein directly to an artery?
a. Graft
b. Catheter
c. Fistula
d. Shunt
✔️ Correct Answer: C
Rationale:
A fistula (Option C) is a permanent vascular access created by surgically
connecting a vein directly to an artery, allowing the vein to enlarge and
thicken over time. This direct connection, also known as an
arteriovenous (AV) fistula, provides the best long-term access for
hemodialysis with the lowest rate of complications. The fistula must
"mature" for several weeks to months before it can be used for dialysis.
Once mature, it can be punctured with dialysis needles and will allow
the blood flow rates needed for effective treatment.
Option A is incorrect because a graft uses a piece of synthetic tubing to
connect an artery to a vein, rather than using the patient's own vessels.
Option B is incorrect because a catheter is a plastic tube placed in a
large central vein for short-term or temporary access. Option D is
incorrect because a shunt was the first permanent vascular access used
in 1960 but is no longer commonly used.
A dialysis patient's laboratory results show a serum albumin level of 2.8
g/dL. Which condition does this finding most likely indicate?
,a. Anemia
b. Malnutrition
c. Hyperkalemia
d. Fluid overload
✔️ Correct Answer: B
Rationale:
Low serum albumin levels (<3.5 g/dL) may indicate that a patient is
undernourished or malnourished (Option B). Albumin is a blood protein
that serves as an important marker of nutritional status in dialysis
patients. Malnutrition is common in dialysis patients and raises their
risk of death. The target serum albumin level for dialysis patients is 4.0
g/dL or higher. Low albumin levels may result from inadequate protein
intake, inflammation, or protein loss during dialysis. Monitoring
albumin levels is essential for assessing nutritional status and guiding
dietary interventions.
Option A is incorrect because anemia is a shortage of red blood cells,
assessed by hemoglobin and hematocrit levels. Option C is incorrect
because hyperkalemia refers to elevated potassium levels. Option D is
incorrect because fluid overload is assessed by weight gain, edema, and
blood pressure changes.
A hemodialysis patient experiences severe fatigue, trouble with mental
focus, and reduced immune function. Laboratory tests reveal a shortage
of oxygen-carrying red blood cells. Which condition is the patient most
likely experiencing?
a. Hyperkalemia
b. Anemia
, c. Malnutrition
d. Uremia
✔️ Correct Answer: B
Rationale:
Anemia is a shortage of oxygen-carrying red blood cells that causes
severe fatigue, trouble with mental focus, reduced immune function,
and many other problems (Option B). Anemia is common in kidney
failure due to reduced production of erythropoietin (EPO) by the failing
kidneys, iron deficiency, and loss of blood through tests and dialysis
itself. The kidneys normally produce EPO, which tells the bone marrow
to make red blood cells. When kidney function declines, EPO production
decreases, leading to anemia. Treatment may include iron
supplementation and erythropoiesis-stimulating agents.
Option A is incorrect because hyperkalemia refers to elevated
potassium levels, which can cause muscle weakness and cardiac
arrhythmias. Option C is incorrect because malnutrition is assessed by
low albumin levels. Option D is incorrect because uremia is a build-up of
wastes in the blood.
A dialysis patient is scheduled for a procedure to open a narrowed
blood vessel in their vascular access. A small balloon is threaded
through the vessel and gently inflated to push the vessel walls open.
What is this procedure called?
a. Angioplasty
b. Thrombectomy
c. Anastomosis
d. Stent placement
