Q1.
Which type of diet would the nurse expect the primary health care
provider to prescribe for a client diagnosed with rheumatoid arthritis?
A. High-protein ketogenic diet
B. Low-carbohydrate diet
C. Regular diet with vitamins and minerals
D. Liquid-only diet
Correct Answer: C
Rationale:
Clients with rheumatoid arthritis need balanced nutrition to support
immune function and reduce inflammation. A regular diet with adequate
vitamins and minerals prevents deficiencies and supports joint health.
,Highly restrictive diets may worsen fatigue and muscle loss. Proper
nutrient intake improves overall physical resilience.
Q2.
After teaching an obese client how to calculate BMI, which statement
indicates effective learning?
A. “I should lose at least half a pound to one pound each week.”
B. “I will skip meals to lose weight faster.”
C. “I should avoid drinking water during meals.”
D. “I will take diet pills daily.”
Correct Answer: A
Rationale:
A safe and sustainable weight loss goal is 0.5–1 pound per week. Rapid
weight loss can cause muscle wasting and metabolic imbalance. The
statement reflects understanding of healthy weight management
principles. This demonstrates effective learning of BMI-guided goals.
Q3.
Which information should the nurse include in the teaching plan for a
client who will receive TPN at home?
A. How to prepare solid meals
B. Demonstrating how to test capillary glucose levels
C. How to insert the IV catheter
D. How to mix TPN solutions
Correct Answer: B
Rationale:
TPN solutions contain high glucose concentrations, increasing risk for
,hyperglycemia. Clients must monitor blood glucose to detect
complications early. Catheter insertion and solution preparation require
sterile clinical training and are not patient responsibilities. Glucose
monitoring promotes safe home management.
Q4.
Which criteria for bariatric surgery would the nurse explain to an
adolescent expressing desire for the procedure?
A. Ability to run one mile
B. BMI of at least 40 with severe obesity
C. Daily vitamin intake only
D. No family history of obesity
Correct Answer: B
Rationale:
Bariatric surgery eligibility typically requires a BMI ≥40 or ≥35 with
comorbidities. This ensures surgery is medically necessary and
beneficial. Physical ability or family history alone does not determine
eligibility. Meeting BMI criteria reduces surgical risk and improves
outcomes.
Q5.
Which information would the nurse include when teaching parents about
developmental nutritional needs of adolescents?
A. Adolescents need fewer calories than adults
B. Adolescents require iron daily
C. Adolescents should avoid carbohydrates
D. Adolescents no longer need calcium
Correct Answer: B
, Rationale:
Adolescents experience rapid growth requiring increased iron for blood
volume expansion and muscle development. Iron deficiency is common
during this stage. Avoiding iron can lead to anemia and fatigue. Daily
iron intake supports healthy maturation.
Q6.
Which action would the nurse take when a client is receiving TPN?
A. Monitor weight daily
B. Allow solution to hang longer than 24 hours
C. Discontinue vital sign monitoring
D. Encourage oral fluids only
Correct Answer: A
Rationale:
Daily weight monitoring evaluates hydration and effectiveness of
nutritional therapy. TPN solutions must be discarded after 24 hours to
prevent infection. Vital signs remain essential to detect complications.
Weight trends provide direct insight into fluid balance.
Q7.
Which nursing action addresses nutritional needs for a depressed client
who sits alone and shows no interest in eating?
A. Force the client to eat
B. Stay with the client during meals
C. Offer only snacks
D. Delay meals
Correct Answer: B
