A patient is admitted to the ICU after sustaining a concussion and blunt abdominal trauma to the right upper
quadrant in a domestic dispute. The patient's vital signs are BP 145/86 mm Hg, pulse 86 beats/min, respiration 15
breaths/min, and temperature 98.8° F. The nurse is monitoring the patient's bowel sounds, abdominal
tenderness, and abdominal girth frequently. Which of the following laboratory parameters is especially important
for the nurse to closely monitor for bleeding in this patient?
A.
Platelet count
B.
Protime
C.

Hematocrit
D.
Mean corpuscular volume –
Correct Answer :C. Hematocrit
Common injuries resulting from blunt abdominal trauma can include injury to the liver, spleen, mesenteric
vessels, pancreas, or kidneys. In a nonoperative approach to blunt abdominal trauma, observation and
monitoring include serial hematocrits to evaluate for intra-abdominal bleeding. The platelet count does not
fluctuate unless there is a disease process (e.g. cirrhosis, leukemia) or significant blood loss. Protime is a monitor
of coagulation status and can be prolonged without active bleeding. Mean corpuscular volume measures the
average volume or size of a single RBC and is used in classifying anemias.
Which of the following is associated with chest pain, confusion, and petechiae?
A.
Dissecting aneurysm
B.
Fat embolism
C.
Pneumothorax
D.
Myocardial infarction - Correct Answer :B. Fat embolism
Chest pain, confusion, and petechiae are suggestive of a fat embolism, especially within the first 48 to 72 hours
after a long-bone fracture.
The clincher is the petechiae. None of the other choices would cause petechiae.
Which type of shock is most likely to be iatrogenic?
P 2
, • CCRN test bank 09/06/2026
A.
Hypovolemic
B.
Cardiogenic
C.
Septic
D.
Neurogenic - Correct Answer :C. Septic
Iatrogenic means caused by treatment or diagnostic procedures or medically induced. Septic shock is the type of
shock most likely to be iatrogenic. Significant contributors include immunosuppressive medications and
therapies and invasive procedures.
A patient had a craniotomy 2 days ago for removal of a tumor. He is awake and talking to the nurse and
demonstrates no neurologic deficit. Blood pressure is 110/80 mm Hg, pulse is 92 beats/min, and respiratory rate
is 22 breaths/min. Urine outputs have been approximately 60 ml/hr over the last 2 days, but he has had a recent
change. He has had 300 to 400 ml/hr of urine output over the last several hours. The urine has a specific gravity
of 1.002. The nurse checks his serum glucose and finds that it is 100 mg/dl. The cause of hypernatremia in this
patient is:
A.
sodium retention.
B.
water loss.
C.
water gain.
D.
aldosterone excess. - Correct Answer :B. water loss

This case is an example of diabetes insipidus, which is caused by a lack of antidiuretic hormone (ADH). ADH
causes water retention in the renal tubules but not sodium retention, so eliminate sodium retention. A lack of
ADH causes water loss not water gain, so eliminate water gain. Diabetes insipidus does not have anything to do
with aldosterone. The hypernatremia is a concentration effect caused by water loss. This sometimes is called
hypovolemic hypernatremia.
If a patient has a palpable radial pulse, the systolic blood pressure (BP) is at least:
A.
50 mm Hg.
B.
60 mm Hg.
C.
70 mm Hg.
D.
80 mm Hg. - Correct Answer :D. 80 mm Hg.
If the radial artery can be palpated, the systolic BP is at least 80 mm Hg. If the brachial artery can be palpated,
the systolic BP is at least 70 mm Hg. If only the carotid artery can be palpated, the systolic BP is approximately
60 mm Hg.
Your patient has an increase in venous oxygen saturation (SvO2) along with a decrease in oxygen consumption
(VO2) and pH. What do you suspect?
A.
Early septic shock
B.
Cardiogenic shock
C.
Hemorrhagic shock
D.
