Nursing Elites

1. Which neurotransmitter is most closely associated with mood regulation and is targeted by antidepressants?

• A. Serotonin
• B. Dopamine
• C. GABA
• D. Acetylcholine

Correct answer: A

Rationale: The correct answer is A: Serotonin. Serotonin plays a vital role in mood regulation, and its imbalance is often associated with depression. Many antidepressants function by boosting serotonin levels in the brain. Dopamine (Choice B) is more linked to reward and pleasure pathways in the brain, not primarily targeted for mood regulation. GABA (Choice C) is an inhibitory neurotransmitter that helps reduce neuronal excitability, not primarily associated with mood regulation. Acetylcholine (Choice D) is involved in muscle movement and cognitive functions, not the primary target of antidepressants for mood regulation.

2. An 8-year-old is placed in 90-90 traction for a fractured femur resulting from a motor vehicle collision. Which finding requires further action by the nurse?

• A. No bowel movement for two days
• B. Mother assists child in changing positions
• C. Weights are touching the foot of the bed
• D. Child is able to move the toes freely when tickled

Correct answer: C

Rationale: The correct answer is C. In 90-90 traction, the weights should hang freely and not touch the foot of the bed to maintain proper traction and bone alignment. Option A is not necessarily a concern as bowel movements can be influenced by various factors, including diet changes and pain medication. Option B indicates good caregiver involvement, promoting comfort and preventing complications. Option D demonstrates neurovascular function, which is a positive finding. Therefore, the weights touching the foot of the bed is the finding that requires immediate attention to ensure the effectiveness of the traction.

3. Based on the principle of asepsis, which situation should the nurse consider to be sterile?

• A. A one-inch border around the edges of a sterile field set up in the operating room
• B. A sterile glove that the nurse thinks might have touched her hair
• C. A wrapped, unopened sterile 4x4 gauze pad placed on a damp tabletop
• D. An open sterile Foley catheter kit set up on a table at the nurse's waist level

Correct answer: D

Rationale: The correct answer is D because an open sterile Foley catheter kit set up at waist level is considered sterile if it has not been contaminated. Choice A is incorrect because the one-inch border around a sterile field is considered non-sterile. Choice B is incorrect because a sterile glove that might have touched the nurse's hair is likely contaminated. Choice C is incorrect because a wrapped, unopened sterile gauze pad placed on a damp tabletop may have become contaminated.

4. A child with glomerulonephritis is admitted in the acute edematous phase. Based on this diagnosis, which nursing intervention should the nurse plan to include in the child's plan of care?

• A. Recommend parents bring favorite snacks
• B. Encourage ambulation daily to the playroom
• C. Measure blood pressure every 4 to 6 hours
• D. Offer a selection of fresh fruit for each meal

Correct answer: C

Rationale: The correct answer is to measure blood pressure every 4 to 6 hours. Monitoring blood pressure frequently is crucial in managing glomerulonephritis, as hypertension is a common complication during the acute edematous phase. Choice A is incorrect as it does not address the specific needs of a child with glomerulonephritis. Choice B is incorrect as excessive activity may not be suitable during the acute phase, as rest and monitoring are more important. Choice D is incorrect as the focus should be on monitoring vital signs rather than meal options.

5. A client is recovering from abdominal surgery and has a nasogastric (NG) tube in place. The nurse notes that the client is experiencing nausea despite the NG tube being patent. What is the nurse's best action?

• A. Increase the suction on the NG tube.
• B. Administer an antiemetic as prescribed.
• C. Irrigate the NG tube with saline.
• D. Reposition the client to the left side.

Correct answer: B

Rationale: Administering an antiemetic as prescribed is the best action for the nurse to take when a client with a patent NG tube is experiencing nausea. This intervention can help relieve nausea effectively. Increasing suction on the NG tube (Choice A) may not address the underlying cause of the nausea and could potentially lead to complications. Irrigating the NG tube with saline (Choice C) is not indicated for addressing nausea in this scenario. Repositioning the client to the left side (Choice D) is not the priority intervention for nausea in a client with a patent NG tube.
