Board Preparation
Question 1
A physician orders nutritional therapy administered via a central vein for a client who
cannot take food orally. What is the correct term for this intervention?
A. Enteral feeding
B. Peripheral parenteral nutrition
C. Total parenteral nutrition
D. Tube feeding
Correct Answer: C. Total parenteral nutrition
Rationale:
Total parenteral nutrition (TPN) is a method of delivering complete nutritional
support intravenously through a central vein when the gastrointestinal tract cannot be
used. Enteral feeding (A) uses the GI tract and is not appropriate when oral intake is
impossible. Peripheral parenteral nutrition (B) is less concentrated and not suitable for
long-term or full nutritional needs. Tube feeding (D) still requires a functioning GI
tract, so it is inappropriate in this case.
Question 2
Which client is most appropriate for total parenteral nutrition (TPN)?
A. A client with controlled hypertension
B. A client with colitis and severe bloody diarrhea
C. A client recovering from minor surgery
D. A client with mild dehydration
Correct Answer: B. A client with colitis and severe bloody diarrhea
Rationale:
TPN is indicated when the gastrointestinal tract cannot adequately absorb nutrients.
Severe colitis with bloody diarrhea suggests significant GI dysfunction. The other
options involve conditions where the GI tract is still functional, meaning oral or
enteral nutrition would be preferred.

Question 3
Which nursing interventions help prevent pressure injuries? (Select all that apply)
A. Turn the client every 2 hours
B. Provide incontinence care regularly
C. Encourage fluids every 2 hours
D. Restrict mobility completely
Correct Answer: A, B, C
Rationale:
Frequent repositioning (A), hygiene and moisture control (B), and adequate hydration
(C) reduce pressure injury risk by improving tissue perfusion and skin integrity.
Restricting mobility (D) increases risk and is contraindicated.
Question 4
Which interventions correctly demonstrate safe use of heat or cold therapy? (Select all
that apply)
A. Checking skin frequently in elderly patients using heating pads
B. Filling ice bags completely to maximize cooling
C. Covering cold packs with protective material
D. Applying heat continuously for 12 hours
Correct Answer: A, C
Rationale:
Elderly clients are at increased risk of burns (A), and cold packs should be covered to
prevent tissue damage (C). Overfilling ice bags (B) and prolonged heat application (D)
increase risk of tissue injury and are unsafe.
Question 5
A client with an ankle sprain states: “I will place cloth between my skin and the ice
pack.” What does this indicate?
A. Ineffective teaching
B. Correct understanding
C. Need for analgesics
D. Risk of infection
Correct Answer: B. Correct understanding
,2026/2027
Rationale:
Placing a barrier between skin and ice prevents frostbite and tissue damage, indicating
proper understanding. No evidence suggests infection risk or need for medication
based on this statement.
Question 6
Which interventions help prevent thrombophlebitis in postoperative clients? (Select
all that apply)
A. Early ambulation
B. SCDs and compression stockings
C. Prolonged bed rest
D. Range of motion exercises
Correct Answer: A, B, D
Rationale:
Movement, compression devices, and ROM exercises promote venous return and
prevent clot formation. Prolonged immobility (C) increases thrombus risk.
Question 7
A client independently moves all joints through full motion. What type of range of
motion is this?
A. Passive ROM
B. Active ROM
C. Assisted ROM
D. Limited ROM
Correct Answer: B. Active ROM
Rationale:
Active ROM occurs when the client moves their joints independently. Passive ROM
requires caregiver assistance. Assisted ROM involves shared effort.
Question 8
A stroke client requires long-term tube feeding. Which tube is most appropriate?
A. Nasogastric tube
B. Orogastric tube
C. Gastrostomy tube
D. Endotracheal tube
, 2026/2027
Correct Answer: C. Gastrostomy tube
Rationale:
Gastrostomy tubes are ideal for long-term feeding because they bypass the upper GI
tract safely and reduce irritation compared to nasal tubes.
Question 9
What is the most appropriate action if a UAP is unsure about safely ambulating an
obese client?
A. Allow UAP to proceed alone
B. Ask another UAP to assist
C. RN assists the UAP
D. Cancel ambulation
Correct Answer: C. RN assists the UAP
Rationale:
Safety requires proper staffing and supervision. The RN must ensure safe mobility
techniques are used. Delegating without support increases risk of falls.
Question 10
A client reports pain before scheduled ambulation. What is the best nursing action?
A. Force ambulation
B. Delay ambulation and medicate
C. Cancel ambulation permanently
D. Ignore pain complaint
Correct Answer: B. Delay ambulation and medicate
Rationale:
Pain must be controlled before mobility to ensure safety and cooperation. Ambulation
should not be forced or permanently canceled.
Question 11
What is the first safety action when an older adult requests assistance to the bathroom?
A. Provide walker
B. Assess need for assistance
C. Call physiotherapy
D. Encourage independence
