test bank foundations of nursing

Correct Answer: A

Rationale: The correct answer is A: Drink more water to prevent further dehydration. Given the patient's fair skin turgor, fatigue, weakness, warm and dry skin, elevated pulse rate, and slightly elevated urinary sodium level, these are signs of dehydration. Increasing water intake would help improve the patient's hydration status. Other choices are incorrect because B (calorie-dense fluids) does not address the dehydration issue, C (milk and dairy products) does not directly address the symptoms presented, and D (grapefruit juice) is not essential for hydration in this case.

Correct Answer: C

Rationale: The correct answer is C: Baked apricot chicken and steamed broccoli. This menu selection is the best choice for potentially reducing the risks of cancer due to several reasons. Baked apricot chicken is a lean protein source without the harmful effects of excessive red or processed meats, which are linked to an increased cancer risk. Apricots are rich in antioxidants like Vitamin C and beta-carotene, which can help protect cells from damage that may lead to cancer. Broccoli is a cruciferous vegetable containing compounds like sulforaphane that have anti-cancer properties. Steaming broccoli helps retain its nutrients better compared to frying or overcooking. Therefore, this menu selection is a balanced, nutritious choice that includes cancer-fighting ingredients and avoids potentially harmful foods like red meats or fried items.

Correct Answer: C

Rationale: The correct answer is C: anticonvulsant. Magnesium sulfate is used in the treatment of preeclampsia to prevent seizures, making it an anticonvulsant. It works by reducing neuromuscular excitability and stabilizing nerve cell membranes. Choice A (diuretic) is incorrect because magnesium sulfate does not primarily promote diuresis. Choice B (tocolytic) is incorrect as it does not inhibit uterine contractions. Choice D (antihypertensive) is incorrect because although magnesium sulfate can help lower blood pressure in preeclampsia, its primary indication in this case is for seizure prophylaxis.

Correct Answer: B

Rationale: The correct answer is B: TPN administered via a peripherally inserted central catheter. TPN provides comprehensive nutrition intravenously, bypassing the GI tract, which is important for patients unable to tolerate oral intake. A peripherally inserted central catheter allows for long-term TPN administration. A: Administration of parenteral feeds via a peripheral IV is not ideal for long-term nutrition as it may not provide complete nutrition. C: Insertion of an NG tube may not be feasible due to the tumor location and the patient's inability to tolerate oral intake. D: Maintaining NPO status and IV hydration alone may lead to malnutrition over time as it does not provide adequate nutrition.

Correct Answer: D

Rationale: The correct answer is D because being aware of patients' medication regimens allows nurses to identify and monitor ototoxic medications that can cause hearing loss. By collaborating with other professionals, nurses can adjust medications or recommend alternative treatments to prevent or minimize ototoxicity. This proactive approach directly targets the root cause of potential hearing loss. A: Understanding types of hearing loss is important but does not directly prevent ototoxicity. B: Educating about age-related changes in hearing does not address ototoxicity prevention. C: Educating about noise exposure risks is important for overall hearing health but does not specifically prevent ototoxicity.
