The blood pH is a measure of which of the following?
A.
P 1
, • CCRN PRACTICE 09/09/2026
EXAM
Ability of the lungs to eliminate carbon dioxide
B.
Ability of the kidneys to eliminate nonvolatile acids
C.
The hydrogen ion concentration in the blood
D.
The balance between carbonic acid and hydrogen ions –
Correct Answer :C. The hydrogen ion concentration in the blood
The blood pH is an indirect and inverse measurement of the hydrogen ion concentration. If the pH goes up (i.e.,
alkalosis), the hydrogen concentration is down. If the pH goes down (i.e., acidosis), the hydrogen concentration
is up. Blood pH is a reflection of the balance between carbonic acid (acid regulated by the lungs) and
bicarbonate (base regulated by the kidneys)
A 45-year-old woman is admitted with deep venous thrombosis and pulmonary embolism. She has received a
heparin bolus and has been on a continuous heparin drip for 3 days. If the patient develops heparin-induced
thrombocytopenia (HIT), what clinical sign would the nurse expect to see first?
A.
Surface bleeding from wounds and IV sites
B.
Hematuria
C.
Petechiae
D.
Bleeding from gums - Correct Answer :C. Petechia
HIT is an immune-mediated adverse effect of heparin. It causes thrombosis and thrombocytopenia. The first
clinical sign of a decrease in platelet quantity or quality is petechiae.

Which of the following assessment findings is specific to hemothorax rather than pneumothorax?
A.
Chest or shoulder pain
B.
Diminished or absent breath sounds
C.
Tachypnea
D.
Dullness to percussion - Correct Answer :D. Dullness to prercussion
Percussion helps to differentiate various densities such as fluid versus air.
Which of the following would be the earliest auscultatory finding in left ventricular failure (LVF)?
A. Crackles
B. S3
C. Murmur of mitral regurgitation
D. Pericardial friction rub - Correct Answer :B. S3
LVF would be the most subtle because early changes are usually subtle changes. Choose "S3."
A patient with a triple-lumen subclavian catheter has been receiving total parenteral nutrition, maintenance
fluids, and antibiotics by the catheter. He has been slightly confused. Suddenly he grasps the catheter and pulls it
out. He then complains of shortness of breath, and his pulse oximetry indicates an SpO2 of 84%. How should this
patient be positioned?
A. Head down, left side
P 3
, • CCRN PRACTICE 09/09/2026
EXAM
B. Head down, right side
C. Head of bed elevated, left side
D. Head of bed elevated, right side - Correct Answer :A. Head down, left side
Envision a big air bubble in the patient's heart. Think: what position would decrease the movement of the air
embolism out of the right side of the heart. Chose "Head down, left side."
Oxygen delivery (DO2) is the product of which of the following?
A.
PaO2, hemoglobin, mean arterial pressure
B.
SaO2, hemoglobin, cardiac output
C.
SvO2, cardiac index, SaO2
D.
PaO2, mean arterial pressure, SvO2 - Correct Answer :B. SaO2, hemoglobin, cardiac output
Oxygen is delivered from the arterial end, so choose an option that has SaO2
Which of the following is the most significant complication of status asthmaticus?
A.
Pulmonary embolism
B.
Acute respiratory failure
C.
P 4
