Which of the following responses indicates sympathetic nervous system function?

Correct Answer: A

Rationale: The correct answer is A because tachycardia (increased heart rate) and dilated pupils are classic responses of the sympathetic nervous system activation. Sympathetic nervous system is responsible for the fight or flight response, leading to increased heart rate and dilated pupils to prepare the body for quick action. Choice B is incorrect because hypoglycemia and headache are not specific to sympathetic nervous system function. Choice C is incorrect because increased peristalsis and abdominal cramping are more indicative of parasympathetic nervous system activity. Choice D is incorrect because pupil constriction and bronchoconstriction are actions of the parasympathetic nervous system, responsible for rest and digest functions.

Correct Answer: D

Rationale: The correct answer is D, suggesting the use of glasses or contact lenses. This is because as older clients experience lens changes associated with aging, they may develop presbyopia or other vision issues that can be corrected with corrective lenses. Glasses or contact lenses can help improve their vision and quality of life. A, offering teaching aids with large-sized letters, may be helpful for clients with visual impairments but may not directly address the specific lens changes associated with aging. B, suggesting reduced visual activity, is not beneficial as it may further limit the client's engagement in daily activities and social interactions. C, suggesting the use of eye drops for comfort, may provide temporary relief for dry eyes but does not address the underlying lens changes affecting vision.

Correct Answer: A

Rationale: The presence of redness, swelling, and induration at the wound site are indicative of infection. Redness and swelling suggest inflammation, while induration indicates tissue hardening and can be a sign of infection spreading. Infection can delay healing and lead to complications if not treated promptly. Evisceration refers to wound opening with protrusion of internal organs, not indicated by the symptoms. Dehiscence is the partial or complete separation of wound layers, not represented by the symptoms. Hemorrhage involves excessive bleeding, which is not described in the scenario. Therefore, choice A is correct as it aligns with the signs observed and is the most appropriate response for the situation.

Correct Answer: D

Rationale: Autoimmunity is when the immune system mistakenly attacks the body's own cells. Choice D is correct because it reflects this key feature - the inability to differentiate self from nonself. This leads to the immune system targeting healthy tissues. Choices A, B, and C are incorrect as they do not accurately describe autoimmunity. Choice A refers to endotoxins destroying B cells, which is not the definition of autoimmunity. Choice B mentions overproduction of reagin antibody, which is not related to autoimmunity. Choice C is incorrect as autoimmunity does not involve depression of the immune response but rather an inappropriate immune response.

Correct Answer: C

Rationale: The correct answer is C because performing a physical examination is the method nurses use to establish a patient's database. This involves directly assessing the patient's physical condition, gathering data on their health status, and identifying any abnormalities or concerns. Reviewing literature (A) is important but not a direct method of collecting patient data. Checking orders for tests (B) is part of data collection but not the initial step. Ordering medications (D) is a treatment action, not data collection.

Correct Answer: C

Rationale: The correct answer is C: He walked home in a cold rain. Walking in cold rain can lead to vasoconstriction, which impairs blood flow, increasing the likelihood of a sickle cell crisis in individuals with sickle cell disease. This can cause red blood cells to sickle and block blood vessels, leading to pain and tissue damage. Choices A, B, and D do not directly affect the physiology of sickle cell disease and are less likely to trigger a crisis.

Correct Answer: C

Rationale: The correct answer is C: Urine output increases. This indicates digoxin's effectiveness as it improves cardiac output by enhancing contraction strength. Increased urine output signifies improved kidney perfusion due to enhanced cardiac function. Option A is incorrect as decreased urine output indicates poor kidney perfusion. Option B is incorrect as digoxin aims to regulate heart rate, not necessarily make it higher than 95. Option D is incorrect as a heart rate lower than 50 could indicate digoxin toxicity.

Correct Answer: B

Rationale: The correct answer is B because rifampin can cause discoloration of bodily fluids, including tears. If clients wear contact lenses, they need to be informed that the lenses may become colored due to this medication. This is important for the client's awareness and to prevent any potential harm to their eyes. A: Taking medication with meals is not necessary for rifampin administration. C: Avoiding wearing glasses is not relevant to rifampin treatment. D: Avoiding tuna, aged cheese, and red wine is not specifically related to rifampin use.

Correct Answer: D

Rationale: The correct answer is D: Strawberries. Strawberries are a common allergen due to their high allergenic potential. When taking a dietary history, it is important to identify potential allergens to prevent adverse reactions. Oranges, carrots, and bread are not as commonly associated with allergies compared to strawberries. Identifying common allergens helps in providing safe and appropriate dietary recommendations for clients.
