CRT Exam 1A Questions and Answers
100% Solved | Latest Update
You come upon a patient who is unresponsive and is not breathing. You
had heard from her nurse that she had discussed a do not resuscitate
(DNR) order with her physician. You should - ✔✔Immediate call a code and
begin resuscitation efforts
If there is any doubt regarding a do not resuscitate (DNR) order or when
written orders are not present, resuscitation efforts should be begun.
Formal or informal directives such as "slow code" or "code gray" bypass
the patient's rights and are generally
If the pH of a patient's blood falls below normal: - ✔✔the hemoglobin
saturation for a given PO2 falls. the affinity of hemoglobin for O2 decreases
The impact of variations in blood pH on the affinity of Hb for oxygen is
called the Bohr effect. According to the Bohr effect, a decrease in pH shifts
the oxyhemoglobin dissociation curve to the right. This right shift results in
a decreased Hb affinity for O2, as manifested by a drop in the Hb
saturation for a given PO2.

,While examining a patient in the ICU, you note that they appear somewhat
edematous and the nurse has indicated that the patient's urine output is
"minimal." In what section of the medical record would you check to
determine the patient's fluid balance (intake vs. output)? - ✔✔nurses' notes
and flowsheet
A patient's fluid balance is the relationship between fluid intake and outputs
primarily from urination. It is normally noted in the nurses notes and
flowsheet section of the medical record. The normal fluid intake and output
for adults is 1 to 2 liters per day, or 25 to 50 ml per hour. A positive fluid
balance results from excessive intake and/or decreased output and may
contribute to pulmonary or peripheral edema and hypertension. A negative
fluid balance is generally due to insufficient hydration and/or excessive
urination from medications such as diuretics or theophylline and may lead
to hypotension and low cardiac output.
The normal range for vital capacity in a young healthy male of average size
is:
Choose one answer. - ✔✔4000 to 5000 ml
The normal range for vital capacity is 4000-5000 ml, representing about
80% of the total lung capacity. Normal values vary significantly depending

, on age, sex, and test position. Weight is not a factor in predicting normal
values. Various nomograms are available for predicting normal values.
Incorrect
Compensation for metabolic acidosis occurs via:
Choose one answer. - ✔✔a decrease in blood CO2 levels
In compensatory processes, the system not primarily affected assumes
responsibility for returning the pH to normal. Thus compensation for
metabolic acidosis would occur via changes in blood CO2 levels, as
regulated by the lungs. Specifically, the lungs would increase excretion of
CO2 (by hyperventilation) to offset the drop in HCO3 (base), thus restoring
the pH toward normal.
The diagnostic procedure most likely to confirm the presence of
bronchogenic carcinoma is: - ✔✔tissue biopsy via fiberoptic bronchoscopy
About three-quarters (75-80%) of all bronchogenic carcinomas are
diagnosed by tissue biopsy obtained via fiberoptic bronchoscopy. Cytologic
examination of the sputum is an alternative diagnostic method, but is only
40-60% diagnostic.
Diagnosis of myasthenia gravis may be confirmed via:
Choose one answer. - ✔✔injection of edrophonium (Tensilon)
