A nurse is reinforcing teaching about dietary modifications to help control blood pressure with a client who has hypertension. Which of the following food choices by the client indicates an understanding of the teaching?

A. Use the client's left arm to obtain blood samples: This is correct as using the arm on the opposite side of the mastectomy helps avoid additional stress or injury to the affected arm, which can help prevent lymphedema.
B. Keep both arms below the level of the client's heart: This is not recommended as elevating the affected arm can help reduce swelling and promote lymphatic drainage.
C. Limit range-of-motion exercises with the affected arm: This is incorrect as range-of-motion exercises are important to prevent stiffness and promote circulation, which helps reduce the risk of lymphedema.
D. Obtain blood pressure readings using the client's right arm: This is incorrect as obtaining blood pressure on the affected side could increase the risk of lymphedema.

A. A client who has Alzheimer's disease and requires assistance to the bathroom: This is important but less urgent compared to the risk of worsening condition in a client with a decreased level of consciousness.
B. A client who has diverticulitis and a temperature of 38.3° C (100.9° F): This is a concern, but it is not as immediately critical as a decreased level of consciousness, which may indicate a more severe underlying issue.
C. A client who has a prescription for a sputum specimen to be obtained before breakfast: While important for diagnostic purposes, this is less urgent compared to a decreased level of consciousness.
D. A client who sustained a head injury 2 days ago and has a decreased level of consciousness: This is correct because a decreased level of consciousness in a client with a recent head injury could indicate a serious complication, such as increased intracranial pressure or worsening of their condition, requiring immediate assessment and intervention.
