Comprehensive REVIEW EXAM
GRADED A+ (2026/2027) WITH
ASWERS AND RATIONALE
(VERIFIED) 98% AND ABOVE
CORRECT SCORE.
Question 1
A nurse is caring for a client with heart
failure. Which assessment finding requires
immediate intervention?
A. Weight gain of 2 lb in 24 hours
B. Crackles in bilateral lung bases
,C. Heart rate of 88 bpm
D. Blood pressure of 138/84 mm Hg
Correct Answer: B
Rationale (Blue Highlight):
Crackles in the lung bases indicate fluid
accumulation and possible pulmonary
edema, which can rapidly compromise
oxygenation and requires immediate
intervention. Weight gain is important but
less urgent.
Question 2
A client with diabetes asks why insulin
should be rotated between injection sites.
The nurse should respond:
,A. To reduce the chance of infection
B. To improve insulin absorption
C. To prevent pain during injection
D. To reduce medication cost
Correct Answer: B
Rationale (Blue Highlight):
Rotating insulin injection sites helps prevent
lipodystrophy, which can interfere with
insulin absorption. Consistent absorption
improves glucose control.
Question 3
Which laboratory value should the nurse
report immediately?
A. Potassium 2.9 mEq/L
B. Sodium 136 mEq/L
, C. Hemoglobin 13 g/dL
D. Calcium 9.2 mg/dL
Correct Answer: A
Rationale (Blue Highlight):
A potassium level of 2.9 mEq/L indicates
hypokalemia, which can cause dangerous
cardiac dysrhythmias and requires prompt
intervention.
Question 4
A postoperative client reports sudden
shortness of breath and chest pain. What is
the nurse’s priority action?
A. Encourage deep breathing
B. Apply oxygen
