Which of the following responses indicates sympathetic nervous system function?

Correct Answer: A

Rationale: The sympathetic nervous system is responsible for the body's "fight or flight" response. Tachycardia (increased heart rate) and dilated pupils are classic responses of the sympathetic nervous system activation during times of stress or danger. These physiological responses prepare the body for action, such as running away from a threat.

Correct Answer: A

Rationale: Nursing care for a patient being prepared for surgery includes conducting a careful assessment of neurologic signs to establish baseline data for post-operative care. Assessing the patient's neurologic status preoperatively is important for early detection of any post-operative complications such as changes in consciousness, sensation, or movement. This baseline data will be used to monitor and evaluate the patient's recovery and response to the surgery, anesthesia, and post-operative care interventions. Planning activities, administering enemas, and explaining post-operative complications are also important aspects of nursing care but assessing neurologic signs is the priority in this scenario.

Correct Answer: D

Rationale: Arcus senilis is a condition characterized by a white or gray ring forming around the cornea and does not typically cause visual problems. It is a common and benign condition often seen in older adults. On the other hand, glaucoma, macular degeneration, and cataracts are all eye conditions that can significantly affect vision and lead to visual impairments in older adults. Therefore, in planning safe care for the older adult, the nurse should recognize that Arcus senilis would not cause visual problems unlike the other conditions mentioned.

Correct Answer: C

Rationale: Halos around lights are a common symptom observed in patients experiencing acute angle-closure glaucoma. This occurs due to the increased intraocular pressure causing corneal edema, which leads to light scattering and the appearance of halos. Other symptoms may include severe eye pain, redness in the eye, decreased vision, and headache. It is important for the nurse to recognize these symptoms promptly as acute angle-closure glaucoma is a medical emergency that requires immediate treatment to prevent permanent vision loss.

Correct Answer: C

Rationale: The nursing care for a client in Addisonian crisis, also known as adrenal crisis, should include offering extra blankets and raising the heat in the room to keep the client warm. Addisonian crisis is a life-threatening condition that occurs when the body does not have enough cortisol and aldosterone, which are hormones produced by the adrenal glands. Symptoms of Addisonian crisis include severe weakness, fatigue, abdominal pain, nausea, vomiting, and low blood pressure. By offering extra blankets and raising the room temperature, the nurse can help prevent hypothermia, which can worsen the client's condition. It is important to maintain the client's body temperature to promote comfort and prevent further complications during Addisonian crisis.
