ANSWERS
1. Metabolic syndrome is characterized by:
a. Abdominal obesity, decreased triglyceride level, increased
HDL level, and hypertension.
b. Hypertension, abdominal obesity, and increased HDL level.
c. Abdominal obesity, increased triglyceride level, decreased
HDL level, and increased fasting blood glucose level.
d. Hypotension, decreased fasting blood glucose level, increased
triglyceride level, and decreased HDL level. - ANSWER C:
Metabolic syndrome (insulin resistance) puts people at risk for
the development of diabetes mellitus and cardiovascular disease,
and is characterized by abdominal obesity (>35 inches in women
and >40 inches in men), increased triglycerides (150), decreased
HDL level (<40 mm Hg in men and <50 mm Hg in women),
elevation of blood pressure (130/ 85 mm Hg), and increased
fasting glucose ( 110 mg/dL). Other indicators include elevation
of C-reactive protein (evidence of a proinflammatory state) and
high levels of fibrinogen (evidence of a prothrombotic state).
2.Parenteral nutrition with a total nutrient admixture that
includes lipids has been ordered for a burn patient for
administration throughout a 24-hour period. When preparing to
administer the solution, the nurse observes that the oil has
separated, forming an obvious layer. Which of the following
options is the correct action to take?
,a. Administer the solution, as oil separation is normal.
b. Mix the solution by shaking the bag until no oil separation is
noticeable.
c. Discard the solution.
d. Return the solution to the pharmacy for the addition of added
emulsifier. - ANSWER C: The total nutrient admixture should
be discarded if there is "cracking" of the lipid emulsion and the
oil separates into a layer. With TNA, all the components of
parenteral nutrition and lipids are admixed together in one
container to create a 3-in-1 formula. Components of parenteral
nutrition generally include proteins, carbohydrates, fats,
electrolytes, vitamins, sterile water, and trace vitamins. While
most postoperative patients need 1500 calories per day to
prevent protein breakdown, those with fever, burns, major
surgery, trauma, or hypermetabolic disease may need up to
10,000 more calories daily.
3. A 30-year-old patient complains of post-operative pain at 8
on a 1-to-10 scale 12 hours after surgery, but is not moaning,
grimacing, or exhibiting any standard physical signs of pain.
The patient last received pain medication 6 hours earlier, and
has orders for morphine every 4 hours as needed and ibuprofen
every 6 hours as needed. Which is the most appropriate action?
a. Administer ibuprofen.
b. Administer morphine.
c. Administer ibuprofen, and if the patient does not feel relief
after one hour post-dose, then administer morphine.
d. Question present family members about the patient's pain
tolerance before making a decision. - ANSWER B: The nurse
,should give morphine, as 8 on a 1 to 10 scale is representative of
severe pain, not uncommon in the first 24 hours after surgery.
Patients have a right to pain control, and the nurse should trust
that the pain is what the patient says it is. Patients may show
very different behavior when they are in pain. Some may cry
and moan with minor pain, and others may exhibit little
difference in behavior when truly suffering. Thus, judging pain
by behavior can lead to the wrong conclusions. Questioning
family members is not appropriate.
4. Q-wave myocardial infarction is characterized by:
a. ST-T wave changes with ST depression that reverses within a
few days.
b. Small infarct size-due to spontaneous reperfusion.
c. Peak CK levels in 12 to 13 hours.
d. Complete coronary occlusion in 80% to 90% of patients. -
ANSWER D: Q-wave myocardial infarction is characterized by
complete coronary occlusion in 80% to 90% of patients.
Abnormal Q waves (wider and deeper) are especially common
in the morning. Infarction is usually prolonged, resulting in
transmural necrosis. Peak CK levels occur in approximately 27
hours. Non-Q-wave myocardial infarction is characterized by ST
changes with ST depression. Infarct is typically non-transmural
and small with coronary occlusion in only 20% to 30% of
patients. Peak CK levels occur in approximately 12 to 13 hours.
5. A nursing team leader delegates a task to an unlicensed
assistive member of the personnel. Who is responsible for
patient outcomes?
, a. The unlicensed person who completes the task
b. Both the team leader and the unlicensed person who
completes the task
c. The team leader who delegates the task
d. The administrative staff - ANSWER C: The nurse who
delegates remains accountable for patient outcomes and for
supervision of the person to whom the task was delegated. The
scope of nursing includes delegation of tasks to unlicensed
assistive personnel, providing those personnel have adequate
training and knowledge. Delegation can be used to manage the
workload and to provide adequate and safe care. Delegation
should be done in a manner that reduces liability by providing
adequate communication.
6. A patient with acute lung injury has crackling, tachypnea,
and cyanosis. Oxygen therapy is instituted to maintain oxygen
saturation at:
a. 85%
b. >90%
c. >95%
d. 98% - ANSWER B: Acute lung injury results in severely
compromised lungs with crackling and wheezing, decreased
pulmonary compliance, and cyanosis, so oxygen therapy is
provided to maintain oxygen saturation >90%. Oxygen should
be administered at 100% because of the mismatch between
ventilation (V) and perfusion (Q), which can result in hypoxia
upon change in positioning. Endotracheal intubation may be
needed if oxygen saturation falls or carbon dioxide levels rise.
7. The normal blood, urea, nitrogen (BUN)/creatinine ratio is:
