Signs of constipation include

Correct Answer: D

Rationale: The correct answer is D: Irritability. Constipation can lead to discomfort and irritability due to the buildup of stool in the intestines. Liquid or frequent stools (A) are typically associated with diarrhea, not constipation. Rapid heart rate (B) is not a common sign of constipation. Fecal incontinence (C) refers to the inability to control bowel movements, which is the opposite of constipation. Therefore, irritability (D) is the most relevant sign of constipation.

Correct Answer: A

Rationale: The correct answer is A: It strengthens their effects. Moisture enhances the transfer of heat/cold to the body, intensifying the effects of warm/cold applications. This accelerates the desired therapeutic outcome. Choices B, C, and D are incorrect. B is inaccurate because moisture does not reduce the effects but rather enhances them. C is irrelevant as moisture does not affect the likelihood of causing injury. D is incorrect as the duration of application is not solely determined by moisture.

Correct Answer: A

Rationale: Step-by-step rationale: 1. Oxygen supports combustion, increasing fire risk. 2. Open flames near oxygen can lead to fires. 3. Nursing assistants must ensure safety by preventing open flames. 4. Oxygen levels should be adjusted by licensed healthcare professionals, not nursing assistants. 5. Clogged tubing requires replacement, not just cleaning. 6. Skin problems require evaluation and intervention by healthcare providers, not nursing assistants. Summary: Choice A is correct as it addresses the critical safety concern of fire hazard with oxygen equipment. Choices B, C, and D are incorrect as they involve tasks that are beyond the scope of practice for nursing assistants.

Correct Answer: B

Rationale: The correct answer is B: Some memory loss occurs. As people age, it is normal for memory to decline slightly due to changes in the brain structure and function. This is a common age-related change supported by research and clinical observations. Responses and reflexes do not speed up with age (A), they actually tend to slow down. Sensitivity of nerve endings in skin typically decreases, not increases (C). Lastly, while vision and taste may weaken with age, they do not become stronger (D). Therefore, the correct answer is B based on the known physiological changes associated with aging.

Correct Answer: B

Rationale: The correct answer is B: Medication and psychotherapy. This is the common set of treatments for anxiety disorders because medication helps manage symptoms by altering brain chemistry, while psychotherapy addresses underlying causes and teaches coping strategies. Choice A is incorrect because electroconvulsive therapy and psychosurgery are not typically used for anxiety disorders. Choice C is incorrect as psychosurgery is not a common treatment for anxiety disorders. Choice D is incorrect because electroconvulsive therapy is not a primary treatment for anxiety disorders. Overall, medication and psychotherapy are the recommended and evidence-based treatments for anxiety disorders due to their effectiveness in addressing both symptoms and root causes.
