Correct Answer: B

Rationale: Step 1: Providing a solution of hydrogen peroxide and water as a mouth rinse helps in reducing the pain of stomatitis by promoting oral hygiene and preventing infections. Step 2: Hydrogen peroxide has antimicrobial properties that can help in reducing bacteria in the mouth, which can worsen stomatitis. Step 3: Rinsing with this solution can also help in cleansing the oral mucosa and reducing inflammation, thereby decreasing pain. Step 4: This intervention directly addresses the nursing diagnosis of impaired oral mucous membrane and is focused on symptom management. Summary: A: Recommending the client to discontinue chemotherapy is not a feasible option as it is essential for treating cancer. C: Monitoring platelet and leukocyte counts is important but does not directly address the pain of stomatitis. D: Checking for signs and symptoms is necessary but does not provide direct relief for the pain of stomatitis.

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: 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: B

Rationale: The correct answer is B: Lung cancer. Lung cancer causes the most deaths in women due to its high mortality rate. It is often diagnosed at an advanced stage, leading to poorer outcomes. Breast cancer, although common, has a lower mortality rate compared to lung cancer. Brain cancer is relatively rare in comparison. Colon and rectal cancer, while significant, do not surpass lung cancer in terms of causing the most deaths in women.

Correct Answer: B

Rationale: To calculate the mL needed for the injection, divide the prescribed dose by the concentration of the medication. In this case, 30 mg ÷ 50 mg/mL = 0.6 mL. However, since the nurse should round up to ensure the full dose is administered, the correct answer is 0.7 mL. Choice A is incorrect as it is rounded down. Choice C is incorrect as it is the exact division without rounding up. Choice D is incorrect as it is rounded up too much.
