1. Which of the following are components of evidence-based
practice?
A. Clinical expertise
B. Patient preferences and values
C. Best available research evidence
D. Institutional policies only
Answer: A, B, C
Rationale: Evidence-based practice combines clinical expertise,
patient preferences, and current research. Institutional policies
may guide practice but are not core components.
2. A nurse is caring for a patient with impaired gas exchange.
Which interventions are appropriate?
A. Encourage deep breathing exercises
B. Administer oxygen as prescribed
C. Restrict fluid intake completely
D. Monitor oxygen saturation regularly
Answer: A, B, D
Rationale: Deep breathing, supplemental oxygen, and
,monitoring oxygen saturation improve gas exchange. Complete
fluid restriction is not indicated unless medically prescribed.
3. Which of the following are signs of fluid volume overload?
A. Peripheral edema
B. Hypertension
C. Dry mucous membranes
D. Jugular vein distention
Answer: A, B, D
Rationale: Fluid overload manifests as edema, elevated blood
pressure, and jugular vein distention. Dry mucous membranes
indicate dehydration.
4. A patient with type 2 diabetes is learning self-
administration of insulin. What should the nurse include?
A. Rotate injection sites
B. Inject insulin into muscle tissue
C. Check blood glucose before injection
D. Store insulin in a freezer
Answer: A, C
Rationale: Rotating injection sites prevents lipohypertrophy,
and checking glucose ensures correct dosing. Insulin should not
be injected into muscle or frozen.
,5. Which of the following indicate effective pain management
in a postoperative patient?
A. Pain score reduction
B. Improved mobility
C. Decreased use of analgesics
D. Patient verbalizes comfort
Answer: A, B, D
Rationale: Pain management is effective when pain decreases,
mobility improves, and the patient feels comfortable. Reduced
analgesic use is not always an indicator.
6. Which are normal vital signs for an adult at rest?
A. Temperature 37°C
B. Heart rate 85 bpm
C. Respiratory rate 20/min
D. Blood pressure 150/95 mmHg
Answer: A, B, C
Rationale: Normal adult vitals include temp 36–37.5°C, HR 60–
100 bpm, RR 12–20/min, BP 90–120/60–80 mmHg. 150/95
mmHg is hypertensive.
7. Which nursing actions prevent infection in a hospitalized
patient?
A. Hand hygiene before and after patient contact
B. Using sterile technique for invasive procedures
, C. Administering antibiotics prophylactically to all patients
D. Cleaning equipment between uses
Answer: A, B, D
Rationale: Proper hygiene, sterile technique, and cleaning
reduce infection. Routine antibiotics are not recommended due
to resistance risk.
8. Which lab values indicate dehydration?
A. Elevated hematocrit
B. Low serum sodium
C. Increased blood urea nitrogen (BUN)
D. Low urine specific gravity
Answer: A, C
Rationale: Dehydration causes hemoconcentration (high
hematocrit) and elevated BUN. Sodium may increase, and urine
specific gravity rises.
9. A patient with chronic pain is prescribed an opioid. What
should the nurse monitor?
A. Respiratory rate
B. Blood pressure
C. Level of consciousness
D. Pain intensity
Answer: A, C, D
Rationale: Opioids can depress respiration and consciousness;
