After surgery the nurse notes that the patient’s urine is dark amber and concentrated. Which of the following does the nurse understand may be the reason for this?

Correct Answer: A

Rationale: The correct answer is A: The sympathetic nervous system saves fluid in response to the stress of surgery. The sympathetic nervous system is responsible for the "fight or flight" response, which includes the conservation of fluids during stressful situations. Dark amber and concentrated urine indicates dehydration, which can be a result of the sympathetic nervous system conserving fluids. B: The sympathetic nervous system does not "diereses" (increase urination) in response to stress. C: The parasympathetic nervous system is not involved in fluid conservation during stress. D: The parasympathetic nervous system does not "diereses" fluid in response to stress.

Correct Answer: C

Rationale: The correct answer is C: 2, 3, and 4. High cholesterol, cigarette smoking, and a sedentary lifestyle are modifiable risk factors for developing hypertension. High cholesterol can lead to atherosclerosis, increasing blood pressure. Smoking can constrict blood vessels, raising blood pressure. Sedentary lifestyle can lead to obesity and overall poor cardiovascular health, contributing to hypertension. Race and age are non-modifiable risk factors. Choice A is incorrect because it includes race, a non-modifiable factor. Choice B is incorrect because it includes age, which is also non-modifiable. Choice D is incorrect because it includes all factors, including non-modifiable ones.

Correct Answer: A

Rationale: The correct answer is A: Postural hypotension. This condition is characterized by a drop in blood pressure upon standing, leading to dizziness. The client's symptoms of dizziness upon standing, along with nosebleeds and blurred vision, are indicative of low blood pressure. Postural hypertension (B) is not a recognized medical condition; White coat hypertension (C) refers to elevated blood pressure readings in a medical setting due to anxiety; White coat hypotension (D) is not a recognized medical condition.

Correct Answer: C

Rationale: The correct answer is C: To comply with the medication regimen. Teaching the older client with TIA to comply with medication regimen is crucial in preventing further TIAs or strokes. Medications like antiplatelets or anticoagulants are often prescribed to manage TIA. This education empowers the client to actively participate in their own health management. Incorrect choices: A: Not to worry about the symptoms that are part of the normal aging process - This is incorrect as TIA symptoms are not considered a normal part of aging and should not be ignored. B: To admit oneself to a rehabilitation center or a nursing home for rehabilitation - This is incorrect as it is not the primary intervention for managing TIA. D: To observe any changes in the nails and skin - This is incorrect as it is not directly related to managing TIA.

Correct Answer: C

Rationale: The correct answer is C: Bacon. Bacon contains the highest kilocalorie among the given choices due to its high fat content. Fat provides 9 kilocalories per gram, while carbohydrates (like in bread and apple) provide 4 kilocalories per gram and protein (like in chicken) provides 4 kilocalories per gram. Bacon, being high in fat, has more kilocalories compared to the other choices. Summary: A: Apple - Low in fat, primarily consists of carbohydrates, hence lower in kilocalories. B: Chicken - Contains protein, lower in kilocalories compared to fat, hence not the highest kilocalorie choice. D: Bread - Mainly consists of carbohydrates, lower in kilocalories compared to fat, making it not the highest kilocalorie choice.
