Correct Answer: B

Rationale: Limiting sodium intake to 2 grams per day (B) is a crucial dietary instruction for clients with heart failure. It helps manage fluid retention and reduces the workload on the heart. Increasing fluid intake (A), avoiding potassium (C), and increasing protein intake (D) are not appropriate dietary instructions for heart failure management.

Correct Answer: B

Rationale: When a client expresses the desire to not be resuscitated, it is essential to inquire if this decision has been discussed with their healthcare provider. This is important to ensure that the client's wishes are appropriately documented and legally binding through the healthcare provider's guidance. It is crucial that healthcare decisions, especially those involving life-saving measures, are well-communicated and documented to respect the client's autonomy and ensure their wishes are honored.

Correct Answer: C

Rationale: When the nurse observes that the client's skin over the sternum 'tents' when gently pinched, it is a classic sign of fluid volume deficit. The appropriate action for the nurse in this situation is to continue the planned nursing interventions aimed at restoring the client's fluid volume. This finding reinforces the need to address the fluid deficit and support the client's recovery.

Correct Answer: D

Rationale: Teaching coping strategies is an appropriate first intervention for a client experiencing sleep difficulties and stress. It can help manage stress and improve sleep without immediately resorting to medication. By teaching coping strategies, the nurse empowers the client to address the underlying issues contributing to his sleep problems rather than just providing a temporary solution. Referring for a sleep study and neurological follow-up may be considered later if the client's sleep issues persist despite implementing coping strategies.

Correct Answer: D

Rationale: Vitamin B12 is an essential nutrient that is predominantly found in animal products. Since individuals following a vegan diet do not consume animal products, they are at a higher risk of vitamin B12 deficiency. Therefore, it is crucial for vegans to include a vitamin B12 supplement in their dietary plan to prevent deficiency-related health issues.
