client. Which site is most appropriate to use?
A. Dorsogluteal muscle
B. Deltoid muscle
C. Vastus lateralis muscle
D. Ventrogluteal muscle
Correct Answer: D. Ventrogluteal muscle
Rationale: The ventrogluteal site is preferred in adults because it is free of major
nerves and blood vessels and provides adequate muscle mass.
2. A nurse is caring for a client with a pressure injury on the sacrum. Which
nursing intervention best promotes wound healing?
A. Keeping the wound open to air
B. Repositioning the client every 2 hours
C. Massaging the reddened area

preventing the spread of infection?
,A. Wearing gloves at all times

B. Blood pressure of 130/80 mmHg
C. Respiratory rate of 18/min
D. Potassium level of 4.0 mEq/L

(COPD). Which intervention is the priority?
,A. Encourage fluid intake
B. Monitor oxygen saturation
C. Teach pursed-lip breathing
D. Assist with ambulation

B. Warm, flushed skin
C. Decreased urine output
D. Elevated blood pressure

the highest priority?
A. Administer the medication by IV push
B. Ensure adequate urine output
C. Dilute the medication with normal saline

hypoglycemia?
A. Polyuria
B. Fruity breath odor
C. Diaphoresis and shakiness
D. Deep, rapid respirations
