Correct Answer: A

Rationale: Shortness of breath is a primary symptom of left-sided heart failure. In this condition, the heart's inability to pump effectively leads to fluid backing up into the lungs, causing difficulty breathing. Edema (swelling), rapid heartbeat, and confusion are more commonly associated with other conditions or right-sided heart failure. Edema is often seen in right-sided heart failure due to fluid accumulation in the body, rapid heartbeat can be a general sign of heart issues, and confusion is more related to decreased brain perfusion in severe heart failure cases.

Correct Answer: A

Rationale: The correct answer is to use the cane on the stronger side. By doing so, the client will have better support and balance. Choice B is incorrect because advancing the cane and the weaker leg at the same time may lead to instability and falls. Choice C is incorrect as using the cane on the weaker side does not provide optimal support. Choice D is incorrect as advancing the cane 30 to 45 cm (12-18 in) with each step is not a standard recommendation for cane use.

Correct Answer: C

Rationale: Cold extremities are a critical sign of impending death as they indicate decreased circulation, leading to poor perfusion to the extremities. This phenomenon occurs as the body redirects blood flow to vital organs, preparing for the end of life. Hypertension and tachycardia are less likely to be seen in the terminal phase and are usually associated with other conditions like shock or sepsis. Diaphoresis, or excessive sweating, may occur in various situations but is not a specific indicator of impending death in this context.

Correct Answer: B

Rationale: The correct instruction when using a cane due to leg weakness is to maintain two points of support on the floor at all times. This provides stability and support while walking. Choice A is incorrect because the cane should be used on the weaker side to provide assistance. Choice C is incorrect as the cane and weak leg should move together for support. Choice D is incorrect as advancing the cane too far with each step may compromise balance and stability.

Correct Answer: D

Rationale: The correct recommendation is to walk for at least 30 minutes every day. Walking stimulates intestinal motility, which can help relieve constipation during pregnancy. Option A is important for overall hydration but may not directly address constipation. Option B is not recommended without healthcare provider approval as some laxatives are contraindicated in pregnancy. Option C, increasing intake of refined grains, may exacerbate constipation due to lower fiber content.
