ANSWERED QUESTIONS
The nurse is caring for an older client who had a large volume of intravenous
solution infused rapidly. What findings should the nurse now anticipate?
A. Lowered blood pressure, thready pulse, hypoventilation
B. Lethargy, tachycardia, diaphoresis
C. Edema, fluctuating blood pressure, glucosuria
D. Elevated blood pressure, bounding pulse, dyspnea - correct-answer -Answer: D.
Elevated blood pressure, bounding pulse, dyspnea
Early findings of fluid volume excess include elevated blood pressure, bounding
pulse, and dyspnea. Severe fluid volume overload leads to heart failure and
pulmonary edema. Sometimes, when you are dealing with options that contain a
series on each line, it helps to compare each item in the series by reading
vertically. For example, you would read: "elevated blood pressure, lowered blood
pressure, edema, and lethargy." Because the client received too much fluid, you
would expect an increase in any findings, so you can eliminate the options with
lowered blood pressure and lethargy. Then read bounding pulse with fluctuating
blood pressure. And lastly compare dyspnea with glucosuria; you can eliminate
the one option with "glucose" because this is new information not given in the
question.

A client is scheduled for an intravenous pyelogram (IVP). After the contrast
material is injected, which client reaction requires an immediate intervention?
A. Salty taste
B. Face flushing
C. Feeling warm
D. Hives - correct-answer -Answer: D. Hives
Hives are one sign of anaphylaxis and require immediate action with an injection
of epinephrine. The other listed reactions are normal (expected), and the client
should be reminded that they may occur.
The nurse provides regular mouth care to the hospice client who is actively dying
at home. The family wants to know why the doctor doesn't order an IV since the
client's mouth seems so dry. What information can the nurse provide to the family
that best answers their question?
A. The client will need to be hospitalized if an IV is started
B. The client will need to have an indwelling catheter inserted if an IV is started
C. Intravenous hydration will increase episodes of delirium
D. Intravenous hydration can delay death - correct-answer -Answer: D.
Intravenous hydration can delay death

Dehydrated clients may experience delirium and may benefit from IV therapy.
However, intravenous hydration does not improve dry mouth and can even delay
death. The nurse should explain that the client's comfort can be enhanced by
providing frequent mouth care and that decreased oral intake is a natural and
non-painful part of the dying process.
The client, diagnosed with an acute myocardial infarction (MI), is admitted to the
cardiac care unit. There is an order for oxygen at 4L/min per nasal cannula. What
is the best rationale for administering oxygen?
A. Saturate the red blood cells
B. Relieve dyspnea on exertion
C. Increase oxygen to ischemic cardiac cells
D. Return skin color to normal tones - correct-answer -Answer: C. Increase oxygen
to ischemic cardiac cells
Anoxia of the myocardium occurs in MI. Oxygen administration may help relieve
dyspnea on exertion and cyanosis associated with the condition. However, the
major purpose is to increase the oxygen concentration in the ischemic, damaged
myocardial cells.
A client with moderate persistent asthma is admitted for a minor surgical
procedure. On admission, the peak flow meter is measured at 480 litres/minute.
Postoperatively the client reports having chest tightness. The peak flow is now 200
litres/minute. What should the nurse do first?
, 4|Page
A. Repeat the peak flow reading in 30 minutes
B. Notify the doctor
C. Administer the PRN dose of albuterol
D. Apply oxygen at 2 litres per nasal cannula - correct-answer -Answer: C.
Administer the PRN dose of albuterol
Peak flow monitoring during exacerbations of asthma is recommended for clients
with moderate-to-severe persistent asthma. This will help determine the severity
of the exacerbation and guide the treatment. A peak flow reading of less than 50%
of the client's baseline reading is a medical alert condition and a short-acting beta-
agonist (such as albuterol) should be taken immediately.
The nurse checks a client diagnosed with chronic obstructive pulmonary disease
(COPD). The client is using oxygen per nasal cannula. Which action would be a
priority for the nurse?
A. Monitor activity tolerance
B. Check for digital clubbing
C. Evaluate SaO2 levels
D. Observe skin color for changes - correct-answer -Answer: C. Evaluate SaO2
levels
The best method for the nurse to use in evaluating a client's oxygenation is to
evaluate the SaO2 using a pulse oximeter. This is an effective alternative to arterial
