Question 1
A nurse is reviewing the arterial blood gas (ABG) results of a client who has
been admitted with respiratory distress. Use the following diagram to identify
the normal reference ranges for arterial blood gas values.

+----------------------------------------------------------+
| ARTERIAL BLOOD GAS (ABG) NORMAL VALUES |
+----------------------------------------------------------+
| |
| pH [ ? ] ---- [ ? ] |
| |
| PaCO2 [ ? ] ---- [ ? ] mm Hg |
| |
| HCO3- [ ? ] ---- [ ? ] mEq/L |
| |
| PaO2 [ ? ] ---- [ ? ] mm Hg |
| |
| SaO2 [ ? ] ---- [ ? ] % |
| |

,+----------------------------------------------------------+
Based on the diagram above, which of the following sets of values represents
the correct normal ABG reference ranges?
A. pH 7.25–7.35; PaCO2 45–55 mm Hg; HCO3- 18–22 mEq/L; PaO2 60–70 mm
Hg; SaO2 85–90%
B. pH 7.35–7.45; PaCO2 35–45 mm Hg; HCO3- 22–26 mEq/L; PaO2 80–100
mm Hg; SaO2 95–100%
C. pH 7.45–7.55; PaCO2 25–35 mm Hg; HCO3- 26–30 mEq/L; PaO2 100–120
mm Hg; SaO2 90–95%
D. pH 7.30–7.40; PaCO2 40–50 mm Hg; HCO3- 20–24 mEq/L; PaO2 70–80
mm Hg; SaO2 88–92%

B. pH 7.35–7.45; PaCO2 35–45 mm Hg; HCO3- 22–26 mEq/L; PaO2 80–100
mm Hg; SaO2 95–100%

RATIONALE: The normal arterial blood gas reference ranges are: pH 7.35–
7.45, PaCO2 35–45 mm Hg, HCO3- 22–26 mEq/L, PaO2 80–100 mm Hg, and
SaO2 95–100%. These values reflect normal acid-base balance and
oxygenation status. Option B correctly identifies all five normal reference
ranges as shown in the diagram.
Question 2
A nurse is interpreting the ECG rhythm strip shown in the diagram below. Use
the diagram to identify the cardiac rhythm.

| Each small box = 0.04 sec Each large box = 0.20 sec |
| |
| R-R interval = 4 large boxes = 0.80 sec |
| P wave present before each QRS |
| PR interval = 3 small boxes = 0.12 sec |
| QRS duration = 2 small boxes = 0.08 sec |

Based on the ECG rhythm strip diagram above, which cardiac rhythm is
displayed?
A. Sinus bradycardia
B. Normal sinus rhythm
C. Sinus tachycardia
D. Atrial fibrillation

, B. Normal sinus rhythm

RATIONALE: The ECG strip shows a regular rhythm with a rate of
approximately 75 beats per minute (60 ÷ 0.80 sec = 75 bpm), which falls
within the normal adult range of 60–100 bpm. There is a P wave present
before each QRS complex, a PR interval of 0.12 sec (normal 0.12–0.20 sec), and
a QRS duration of 0.08 sec (normal less than 0.12 sec). These characteristics
are consistent with normal sinus rhythm.
Question 3
A nurse is reviewing the diagram below, which illustrates the pain assessment
tool known as the Wong-Baker FACES Pain Rating Scale. Use the diagram to
answer the question that follows.
