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. When caring for a client with colostomy, which topical skin preparation should the PN apply around the stoma?

• A. Antiseptic cream
• B. Petroleum jelly
• C. Cornstarch
• D. Stomadhesive

Correct answer: D

Rationale: The correct answer is 'Stomadhesive.' Stomadhesive is a protective barrier used around the stoma to prevent skin irritation and to secure the colostomy bag. This preparation helps to maintain skin integrity and prevent complications such as skin breakdown. Antiseptic cream (Choice A) is not typically used around the stoma as it can irritate the skin. Petroleum jelly (Choice B) is also not recommended as it can interfere with the adhesive properties of the colostomy appliance. Cornstarch (Choice C) is not suitable for application around the stoma as it can promote moisture and lead to skin irritation.

3. 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.

4. Which of the following is MOST LIKELY to increase the risk of a medication error?

• A. Not using abbreviations for medications
• B. Errors in the calculation of medication dosages
• C. Barcoding medication orders
• D. Utilizing unit dose dispensers

Correct answer: B

Rationale: Errors in the calculation of medication dosages are a significant risk factor for medication errors. When dosage calculations are incorrect, it can lead to administering the wrong amount of medication, posing serious harm to the patient. Avoiding abbreviations for medications, barcoding medication orders, and utilizing unit dose dispensers are all strategies aimed at reducing medication errors by enhancing accuracy and safety. Therefore, choices A, C, and D are incorrect as they are practices that help decrease, rather than increase, the risk of medication errors.

5. When administering an analgesic to a client with low back pain, which intervention should the practical nurse implement to promote the effectiveness of the medication?

• A. Massage the lower back and position the client in proper alignment
• B. Encourage the client to ambulate frequently and take deep breaths
• C. Assist the client in performing passive and active range of motion exercises
• D. Give medication with a full glass of water and offer high-fiber foods

Correct answer: A

Rationale: Massaging the lower back and positioning the client in proper alignment can help relieve muscle tension and enhance the effectiveness of analgesics by providing additional comfort and promoting better pain management. This intervention directly addresses the site of pain and can improve the medication's efficacy. Choices B, C, and D are incorrect because while they may have benefits in other situations, they are not directly related to promoting the effectiveness of analgesics in clients with low back pain. Encouraging ambulation and deep breathing, assisting with range of motion exercises, and offering water and high-fiber foods are important for overall patient care but are not specific to enhancing analgesic effectiveness in this context.
