NUR 204 Exam 3 TestBank Questions With Complete
Solutions
____________________ are substances that develop an
electrical charge when dissolved in water. - ANS: Electrolytes
____________________ is the movement of air into and out of
the lungs through the act of breathing. ____________________
refers to the exchange of gases (oxygen and carbon dioxide) in
the lungs. - ANS: Ventilation; Respiration
Pulmonary ventilation (breathing) is the movement of air into
and out of the lungs. Oxygenation of the blood, and ultimately
of organs and tissues, depends on adequate ventilation.
Respiration refers to gas exchangethat is, the oxygenation of
blood and elimination of carbon dioxide in the lungs. Although
the plural form respirations is used to mean breaths when taking
vital signs, this is a misnomer: You cannot measure gas
exchange by counting breaths per minute.
A 62-year-old man with emphysema says, My doctor wants me
to quit smoking. It's too late now, though; I already have lung
problems. Which of the following would be the best response to
his statement?
1) You should quit so your family does not get sick from
exposure to secondhand smoke.
2) You will need to use oxygen, but remember it is a fire hazard
to smoke with oxygen in your home.
3) Once you stop smoking, your body will begin to repair some
of the damage to your lungs.
4) You should ask your primary care provider for a prescription
for a nicotine patch to help you quit. - ANS: 3
,The nurses response should focus on correcting the patients
misinformation rather than on convincing him to stop smoking.
Once a person stops smoking, the body begins to repair the
damage. During the first few days, the person will cough more
as the cilia begin to clear the airways. Then the coughing
subsides, and breathing becomes easier. Even long-time smokers
can benefit from smoking cessation. The suggestions that the
patients family will become ill and that oxygen is a fire hazard
appear to be scare tactics, which can be seen as coercive, and
would not be effective in motivating the patient to stop smoking.
Although asking the primary care provider for a prescription
may help the patient to stop smoking, it does not address his
incorrect belief that it is too late for him to do so.
A client is admitted to the emergency department (ED) in
respiratory distress. The results of his arterial blood gases are the
following: pH = 7.30; PCO2 = 40; HCO3 = 19 mEq/L; PO2 =
80. The nurse interprets the findings as which of the following?
1) Respiratory acidosis with normal oxygen levels
2) Respiratory alkalosis with hypoxia
3) Metabolic acidosis with normal oxygen levels
4) Metabolic alkalosis with hypoxia - ANS: 3
The pH is acidotic. The HCO3 of 19 mEq/L is low and has
moved in the same direction as the pH, indicating a metabolic
disorder. The PCO2 is within normal range with no signs of
compensation. The PO2 level is normal.
A healthcare provider prescribes 250 mL of 0.9% sodium
chloride to be infused over 2 hours. A microdrip infusion set is
being used. What is the drip rate (drops/min) that the nurse
should monitor?
,1) 60
2) 75
3) 125
4) 250 - ANS: 3
Calculate the drip rate by multiplying the number of milliliters
to be infused per hour (hourly rate) by the drop factor in
drops/mL, divided by 60 minutes. An infusion of 250 mL in 2
hours results in an hourly rate of 125 mL/hr.
125 (mL/hr) 60 (drops/mL) = 125 drops/min

A mother of a school-age child seeks healthcare because her
child has had diarrhea after being ill with a viral infection. The
patient states that after vomiting for 24 hours, his appetite has
returned. Which recommendation should the nurse make to this
mother?
1) Consume a diet consisting of bananas, white rice, applesauce,
and toast.
2) Drink large quantities of water regularly to prevent
dehydration.
3) Take loperamide (an antidiarrheal) as needed to control
diarrhea.
4) Increase the consumption of raw fruits and vegetables. -
ANS: 1
The nurse should encourage the patient with diarrhea who has an
appetite to consume a diet that consists of bananas, white rice,
applesauce, and toast. These foods are easy to digest, provide
calories for energy, and help provide a source of calcium. The
patient should sip liquids frequently to prevent dehydration;
large quantities might worsen diarrhea. Medication, such as
, loperamide (Imodium), is usually reserved for chronic diarrhea.
Raw fruits and vegetables may worsen diarrhea.
A mother tells the nurse at an annual well-child checkup that her
6-year-old son occasionally wets himself. Which response by
the nurse is appropriate?
1) Explain that occasional wetting is normal in children of this
age.
2) Tell the mother to restrict her child's activities to avoid
wetting.
3) Suggest time out to reinforce the importance of staying dry.
4) Inform the mother that medication is commonly used to
control wetting. - ANS: 1
The nurse should explain that occasional wetting is normal in
children during the early school years. The mother should
handle the situation calmly and avoid punishing the child.
Medications are occasionally prescribed for nocturnal enuresis
when the child is older and not sleeping at home, but not for
occasional daytime wetting.
A nurse is caring for a patient with a peripheral IV line located
in the right forearm. The patient informs the nurse that the IV
site is burning. Upon assessment the nurse determines that the
IV solution has infiltrated. What site(s) is/are appropriate to
consider when restarting the IV line? Choose all that apply.
1) Left hand
2) Right wrist
3) Right antecubital area
4) Right saphenous vein - ANS: 1, 3
When restarting an IV line after an infiltration, you must restart
above the site of infiltration. As a result, the right antecubital
