Correct Answer: B

Rationale: The correct answer is B: Maintain two points of support on the ground at all times. When using a cane for left-leg weakness, the client should hold the cane in the right hand and advance the cane and the weak leg simultaneously. This technique provides the necessary support and stability. Option A is incorrect because the cane should be used on the side opposite the weakness to provide support. Option C is incorrect as advancing the cane too far with each step may cause the client to lose balance. Option D is incorrect because advancing the cane and the strong leg simultaneously does not provide the needed support for the weakened leg.

Correct Answer: B

Rationale: The correct answer is B: Limit alcohol consumption. Alcohol can irritate the stomach lining and worsen peptic ulcer disease. Avoiding dairy products is not necessary unless the client is lactose intolerant. Using antacids frequently may provide symptomatic relief but does not address the root cause of the condition. Drinking coffee can actually stimulate acid production and potentially aggravate peptic ulcers.

Correct Answer: B

Rationale: To administer 10 mg of metoclopramide, the nurse should administer 2 mL (10 mg / 5 mg per mL). Therefore, the correct answer is 2 mL. Choice A (1 mL) is incorrect because it would only deliver 5 mg of metoclopramide, which is half the required dose. Choice C (3 mL) and D (4 mL) are incorrect as they would provide more than the required dose of 10 mg.

Correct Answer: B

Rationale: The correct answer is to advise the client to avoid caffeinated drinks. Caffeine can temporarily increase blood pressure, so avoiding caffeinated drinks can help manage hypertension. Encouraging a low-sodium diet (Choice A) is essential for hypertension management as excess sodium can raise blood pressure. Increasing high-protein foods (Choice C) is not a primary focus in managing hypertension. While reducing fat intake (Choice D) can be beneficial for overall health, it is not the priority in lifestyle modifications for hypertension.

Correct Answer: B

Rationale: Irritability is an early indicator that suctioning is necessary for a client with a tracheostomy. Irritability can signal discomfort or difficulty breathing, which may be due to the need for suctioning to clear the airway. Decreased respiratory rate, bradycardia, and decreased oxygen saturation are not typically early indicators that suctioning is needed in a client with a tracheostomy. These symptoms may occur later if the airway is not cleared promptly.
