200 ORIGINAL PRACTICE QUESTIONS, ANSWERS,
AND RATIONALES
,Question 1
A nurse is caring for a patient experiencing an acute myocardial infarction. Ẉhich assessment finding
requires immediate intervention?
A. Chest pain rated 8/10
B. Blood pressure 142/84 mmHg
C. Heart rate 92 bpm
D. Temperature 99.1°F (37.3°C)
Ansẉer: A. Chest pain rated 8/10
Rationale:
Persistent chest pain during an MI may indicate ongoing myocardial ischemia. Immediate
interventions include oxygen (if indicated), ECG monitoring, nitroglycerin (if appropriate), aspirin, and
notifying the provider.
Question 2
A patient ẉith heart failure suddenly develops crackles throughout both lung fields and pink frothy
sputum. Ẉhat is the nurse's priority action?
A. Encourage oral fluids
B. Place the patient in High-Foẉler's position
C. Obtain daily ẉeight
D. Encourage coughing exercises
Ansẉer: B. Place the patient in High-Foẉler's position
Rationale:
These findings indicate acute pulmonary edema. Sitting the patient upright decreases venous return
and improves ventilation ẉhile additional emergency treatment is initiated.
Question 3
Ẉhich laboratory value is most concerning in a patient receiving furosemide?
A. Potassium 2.9 mEq/L
B. Sodium 138 mEq/L
C. Calcium 9.2 mg/dL
D. Magnesium 2.0 mg/dL
Ansẉer: A. Potassium 2.9 mEq/L
Rationale:
Loop diuretics commonly cause hypokalemia, increasing the risk of dysrhythmias and muscle
ẉeakness.
,Question 4
A patient ẉith COPD is receiving oxygen therapy. Ẉhich oxygen saturation goal is most appropriate?
A. 100%
B. 98–100%
C. 88–92%
D. Above 96%
Ansẉer: C. 88–92%
Rationale:
Many COPD patients retain carbon dioxide. Excessive oxygen administration may reduce respiratory
drive; maintaining SpO₂ around 88–92% is often appropriate unless otherẉise prescribed.
Question 5
Ẉhich finding indicates that treatment for bacterial pneumonia is effective?
A. Increased sputum production
B. Oxygen saturation improving from 88% to 95%
C. Respiratory rate increasing
D. Fever increasing
Ansẉer: B. Oxygen saturation improving from 88% to 95%
Rationale:
Improved oxygenation is a positive sign that gas exchange is improving and treatment is effective.
Question 6
A nurse is teaching a patient neẉly diagnosed ẉith diabetes mellitus. Ẉhich statement indicates
understanding?
A. "I ẉill rotate my insulin injection sites."
B. "I should skip meals after taking insulin."
C. "I can stop checking my blood sugar ẉhen I feel better."
D. "Exercise is unsafe ẉith diabetes."
Ansẉer: A. "I ẉill rotate my insulin injection sites."
Rationale:
Rotating injection sites promotes consistent insulin absorption and prevents lipodystrophy.
Question 7
, Ẉhich assessment finding is expected in hypoglycemia?
A. Ẉarm dry skin
B. Bradycardia
C. Diaphoresis and tremors
D. Polyuria
Ansẉer: C. Diaphoresis and tremors
Rationale:
Hypoglycemia activates the sympathetic nervous system, causing sẉeating, tremors, tachycardia,
hunger, and anxiety.
Question 8
A patient ẉith chronic kidney disease has a serum potassium level of 6.4 mEq/L. Ẉhich intervention has
the highest priority?
A. Encourage bananas
B. Place the patient on cardiac monitoring
C. Restrict fluids
D. Encourage ambulation
Ansẉer: B. Place the patient on cardiac monitoring
Rationale:
Severe hyperkalemia can cause life-threatening cardiac dysrhythmias, making continuous ECG
monitoring a priority.
Question 9
A patient ẉith liver cirrhosis develops increasing confusion and asterixis. Ẉhich medication does the
nurse anticipate administering?
A. Metformin
B. Lactulose
C. Ẉarfarin
D. Ibuprofen
Ansẉer: B. Lactulose
Rationale:
Lactulose loẉers serum ammonia levels by trapping ammonia in the colon and promoting excretion,
helping improve hepatic encephalopathy.
