ADULT HEALTH 1 — D444 OBJECTIVE ASSESSMENT COMPLETE TEST BANK | 200
QUESTIONS | GRADED A+
1. A nurse is caring for a patient with heart failure who has an ejection
fraction of 35%. Which finding should the nurse expect?
A. Bounding peripheral pulses
B. Increased urine output
C. Dry, warm skin
D. Bilateral crackles in the lung bases
E. Bradycardia with regular rhythm
Correct Answer: D. Bilateral crackles in the lung bases
EXPERT RATIONALE: In left-sided heart failure with reduced ejection fraction,
the left ventricle cannot pump blood effectively, causing fluid to back up into the
pulmonary circulation. This leads to pulmonary edema, which presents as bilateral
crackles (rales) heard at the lung bases.
2. A nurse is assessing a patient who is postoperative following a bowel
resection. Which finding requires immediate intervention?
,A. Serosanguineous drainage on the dressing
B. Pain rated 5/10 at the incision site
C. Absent bowel sounds with abdominal rigidity
D. Urinary output of 35 mL/hr
E. Oral temperature of 37.6°C
Correct Answer: C. Absent bowel sounds with abdominal rigidity
EXPERT RATIONALE: Absent bowel sounds combined with abdominal rigidity
suggest peritonitis or paralytic ileus with complications — both surgical
emergencies. Immediate provider notification is required.
3. A nurse is educating a patient newly diagnosed with Type 2 diabetes. Which
statement by the patient indicates a need for further teaching?
A. "I will check my blood glucose before meals."
B. "I should exercise regularly to help control my blood sugar."
C. "I can stop taking my metformin once my glucose is normal."
D. "I need to inspect my feet daily."
E. "I should avoid skipping meals."
Correct Answer: C. "I can stop taking my metformin once my glucose is
normal."
EXPERT RATIONALE: Metformin is a long-term medication for Type 2 diabetes
management. Patients should never self-discontinue medication without provider
guidance, even when glucose levels appear normal.
4. A patient with COPD is receiving oxygen therapy. Which oxygen delivery
method is most appropriate for precise oxygen delivery?
A. Nasal cannula at 6 L/min
,B. Simple face mask at 8 L/min
C. Venturi mask
D. Non-rebreather mask
E. High-flow nasal cannula at 15 L/min
Correct Answer: C. Venturi mask
EXPERT RATIONALE: The Venturi mask delivers precise, controlled FiO₂
concentrations, which is critical for COPD patients who may rely on hypoxic drive.
Too much oxygen can suppress their respiratory drive.
5. A nurse is caring for a patient with a potassium level of 2.9 mEq/L. Which
clinical manifestation should the nurse anticipate?
A. Hypertension
B. Bradycardia
C. Muscle weakness and leg cramps
D. Peaked T waves on ECG
E. Hyperreflexia
Correct Answer: C. Muscle weakness and leg cramps
EXPERT RATIONALE: Hypokalemia (K⁺ < 3.5 mEq/L) causes muscle weakness,
cramps, fatigue, and cardiac dysrhythmias. Peaked T waves are associated with
hyperkalemia, not hypokalemia.
6. A patient is admitted with deep vein thrombosis (DVT). Which intervention
is the priority?
A. Massage the affected leg to promote circulation
B. Administer anticoagulant therapy as prescribed
C. Apply ice packs to the affected extremity
, D. Encourage ambulation immediately
E. Elevate the head of the bed to 90 degrees
Correct Answer: B. Administer anticoagulant therapy as prescribed
EXPERT RATIONALE: Anticoagulation is the cornerstone of DVT treatment to
prevent clot propagation and pulmonary embolism. Massaging the leg is
contraindicated as it can dislodge the clot.
7. A nurse is preparing to administer a blood transfusion. Which action is the
highest priority before initiation?
A. Obtain vital signs 30 minutes into the transfusion
B. Verify the blood type and patient identification with another nurse
C. Flush the IV line with dextrose solution
D. Administer diphenhydramine prophylactically
E. Pre-warm the blood product in a microwave
Correct Answer: B. Verify the blood type and patient identification with
another nurse
EXPERT RATIONALE: Two nurses must verify blood product compatibility and
patient identity to prevent a potentially fatal hemolytic transfusion reaction. This is
the highest safety priority before transfusion initiation.
8. A patient with acute myocardial infarction (MI) is prescribed aspirin. What
is the primary purpose of this medication?
A. Relieve chest pain
B. Inhibit platelet aggregation
C. Reduce cardiac workload
D. Lower blood pressure
