Signs and symptoms of congestive heart failure include

Correct Answer: C

Rationale: The correct answer is C: Swelling in the ankles. In congestive heart failure, the heart's inability to pump effectively leads to fluid buildup in the body, causing swelling in the ankles (edema). Decreased urination (A) is a symptom of kidney dysfunction in heart failure. Weight loss (B) is not typical in heart failure due to fluid retention. Decreased pulse (D) is not a common sign of heart failure; in fact, heart failure can lead to a rapid or irregular pulse.

Correct Answer: C

Rationale: The correct answer is C: Hormones. Hormones are chemical substances produced by the body's endocrine glands that regulate various physiological functions. They act as messengers, controlling processes such as metabolism, growth, and reproduction. Nutrients (A), Minerals (B), and Vitamins (D) are essential for the body but do not regulate bodily functions in the same way as hormones do. Nutrients provide energy and building blocks for the body, minerals are important for various bodily functions, and vitamins play crucial roles in metabolism and overall health. However, hormones specifically serve as signaling molecules that coordinate and control the activities of different organs and systems in the body.

Correct Answer: B

Rationale: The correct answer is B: Rheumatoid arthritis. This is an autoimmune disease where the immune system mistakenly attacks the joints, leading to inflammation and joint damage. Hypothyroidism (Choice A) is a thyroid disorder, not an autoimmune disease. Hepatitis (Choice C) is a viral infection affecting the liver. Gonorrhea (Choice D) is a sexually transmitted bacterial infection, not an autoimmune disease. Rheumatoid arthritis fits the criteria of an autoimmune disease as it involves the immune system attacking the body's own tissues.

Correct Answer: B

Rationale: The correct answer is B: Gastric suctioning. Gastric suctioning involves removing toxins from the stomach by inserting a tube through the nose or mouth. This method is effective in removing ingested poisons before they are absorbed into the bloodstream. Bladder suctioning (A), endotracheal suctioning (C), and intravenous suctioning (D) are not appropriate methods for removing toxins from the body. Bladder suctioning is for draining urine, endotracheal suctioning is for clearing secretions from the airway, and intravenous suctioning does not exist as a valid medical procedure.

Correct Answer: B

Rationale: The correct answer is B because seeking help from a supervisor is an appropriate way for a nursing assistant to reduce and manage stress. By reaching out to a supervisor, the nursing assistant can receive guidance, support, and resources to address the sources of stress effectively. This can help in developing coping strategies and creating a healthier work environment. Talking to a resident about her stress (choice A) may not be appropriate as it can blur professional boundaries. Multitasking excessively (choice C) can lead to increased stress and decreased efficiency. Increasing caffeine intake (choice D) is not a healthy or sustainable way to manage stress.
