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. A client who had a left hemicolectomy is experiencing a low-grade fever on post-operative day three. What is the nurse's best action?

• A. Encourage deep breathing and the use of the incentive spirometer.
• B. Administer antipyretic medication as prescribed.
• C. Notify the healthcare provider immediately.
• D. Increase the client’s fluid intake.

Correct answer: A

Rationale: A low-grade fever on post-operative day three can be a sign of atelectasis, a common post-operative complication. Encouraging deep breathing and the use of the incentive spirometer can help prevent and treat this condition. Atelectasis is often due to shallow breathing, so option A is the best initial action to promote lung expansion. Administering antipyretic medication (option B) may help reduce the fever but does not directly address the underlying cause. Notifying the healthcare provider immediately (option C) is not necessary at this point unless other concerning symptoms are present. Increasing the client’s fluid intake (option D) is important for overall recovery but is not the priority in this scenario.

3. The UAP is caring for a male resident of a long-term care facility who has an external urinary catheter. Which finding should the PN instruct the UAP to report immediately?

• A. Swollen and discolored penile shaft
• B. Prepuce extends over the head of the penis
• C. Leaking urine around the top of the catheter
• D. Moist and excoriated perineal skin folds

Correct answer: A

Rationale: The correct answer is A: Swollen and discolored penile shaft. Swelling and discoloration of the penile shaft may indicate an infection or other complications requiring immediate attention. Prompt reporting allows for timely intervention to prevent further harm to the client. Choice B is incorrect because the prepuce extending over the head of the penis is not an urgent issue. Choice C, leaking urine around the catheter, may require intervention but is not as urgent as the swelling and discoloration described in choice A. Choice D, moist and excoriated perineal skin folds, also needs attention but is not as concerning as the potential complications indicated by the findings in choice A.

4. Which of the following is the best method for confirming nasogastric tube placement?

• A. Auscultating over the stomach while injecting air
• B. Checking the pH of the aspirate
• C. Observing the patient’s response during feeding
• D. Measuring the external length of the tube

Correct answer: B

Rationale: Checking the pH of the aspirate is the most reliable method to confirm nasogastric tube placement as it provides direct evidence of the tube's location in the stomach. When the pH is acidic (pH < 5), it indicates that the tube is correctly placed in the stomach. Auscultating over the stomach while injecting air may not always be accurate, as the sound can be misleading due to various factors. Observing the patient’s response during feeding is not a definitive method for confirming tube placement, as it can be influenced by other factors. Measuring the external length of the tube does not ensure correct placement within the GI tract and can be affected by external factors like patient anatomy.

5. A client is recovering from a right-sided mastectomy and is concerned about lymphedema. What should the nurse include in the discharge teaching to minimize this risk?

• A. Encourage wearing tight clothing on the affected arm.
• B. Advise against lifting heavy objects with the affected arm.
• C. Recommend the client sleep on the affected side.
• D. Suggest frequent massage of the affected arm.

Correct answer: B

Rationale: The correct answer is B: Advise against lifting heavy objects with the affected arm. Lifting heavy objects with the affected arm can increase the risk of lymphedema. It is important for clients to avoid activities that strain the affected arm to minimize the risk of developing lymphedema. Choices A, C, and D are incorrect because wearing tight clothing on the affected arm, sleeping on the affected side, and frequent massage of the affected arm can potentially worsen lymphedema or impede the recovery process. Tight clothing can impede lymphatic flow, sleeping on the affected side can restrict circulation, and frequent massage can exacerbate swelling in the arm.
