PN Exit Exam 2023 Quizlet

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.

Correct Answer: D

Rationale: Providing information about palliative and hospice care services can help the spouse understand the options for managing the client's symptoms and improving the quality of life. This also provides support and guidance during a difficult time. Consulting with the case manager and hospital chaplain may be beneficial for emotional support but may not address the practical aspects of care. Visiting after procedures are done to avoid seeing the client in pain may not foster open communication and support. While participating in the client's care is important, providing information about palliative and hospice care services is the most helpful intervention in this scenario.

Correct Answer: B

Rationale: A heart rate of 120 beats per minute is within the normal range for a 2-month-old infant. Therefore, it is safe to administer the digoxin and document the heart rate as part of routine care. Choice A is incorrect as withholding the medication is not necessary since the heart rate is normal. Choice C is incorrect as there is no need to delay the administration until the next scheduled dose when the heart rate is within the normal range. Choice D is incorrect as the primary nurse is not needed to administer the medication since the heart rate is normal and falls within the safe range for administration.

Acetylcholine (Choice D) is involved in muscle movement and cognitive functions, not the primary target of antidepressants for mood regulation.

Correct Answer: C

Rationale: Having the client sit down in the hallway is the first action the nurse should implement. This is crucial to prevent further strain on the heart and to provide a safer environment for assessment and potential emergency intervention. Administering sublingual nitroglycerin (Choice A) may be appropriate later but should not precede ensuring the client's immediate safety. Assisting the client back to the room (Choice B) may not be advisable if the client is experiencing chest tightness and shortness of breath. Obtaining a 12-lead electrocardiogram (Choice D) is important but would not be the initial action to address the client's immediate symptoms.
