Which neurotransmitter mediates the sympathetic response?

Correct Answer: A

Rationale: The sympathetic nervous system is responsible for our "fight or flight" response to stressful situations. Norepinephrine is the primary neurotransmitter that mediates the sympathetic response, acting on adrenergic receptors in various target tissues. It helps to increase heart rate, elevate blood pressure, dilate air passages in the lungs, and mobilize energy stores in the body to prepare for physical exertion or stress. Acetylcholine is another neurotransmitter involved in the sympathetic nervous system, but norepinephrine is the primary mediator of the fight or flight response.

Correct Answer: C

Rationale: Feeling very sad or withdrawn for more than 2 months is part of the Mental Health Action Signs, but the phrase 'for more than 2 months' is not accurate as symptoms lasting 2 weeks can already be significant.

Correct Answer: D

Rationale: Both lamb and peaches are rich sources of iron. Lamb is a type of red meat that is high in heme iron, which is a form of iron that is easily absorbed by the body. Peaches, on the other hand, are a fruit that contains non-heme iron, which is not as easily absorbed but can still contribute to increasing iron levels in the body. Including these iron-rich foods in the diet of an anemic client can help improve their iron levels and overall health.

Correct Answer: C

Rationale: Early activation of the pediatric basic life support chain, including CPR and early defibrillation, significantly improves survival rates in cardiac arrest.
