Correct Answer: A

Rationale: The correct answer is A because removing sequential compression devices could increase the risk of thromboembolism, making it the priority. Choice B involves assisting with ambulation, which can be done after addressing the urgent need of the client in choice A. Choice C and D involve non-urgent tasks compared to the potential risks associated with not removing sequential compression devices promptly.

Correct Answer: A

Rationale: The correct answer is A. Hospitalized patients are at greater risk for drug-nutrient interactions because they are more acutely ill, often having multiple conditions and treatments that increase the risk of such interactions. Choice B is incorrect as hospital routines interfering with medication timing are not directly related to drug-nutrient interactions. Choice C is incorrect as the toxicity and side effects of drugs do not necessarily relate to interactions with nutrients. Choice D is incorrect as shared responsibility for monitoring does not directly contribute to the increased risk of drug-nutrient interactions in hospitalized patients.

Correct Answer: D

Rationale: The correct answer is D. Under the health services support area concept, the medical care under the MEDCOM is divided into eight geographical areas of responsibility designated as health services support regions, each of which is further subdivided into two or more health service areas. This structure allows for a more organized and efficient delivery of medical care across different regions. Choices A, B, and C are incorrect because they do not accurately describe how medical care under the MEDCOM is divided according to the concept of health services support areas.

Correct Answer: A

Rationale: To obtain accurate cultures of urethral and bladder urine, the nurse should instruct the patient to collect the first 15 mL of urine in one container and the subsequent 50 mL in another. This method ensures that the specimens are separated appropriately for analysis. Choices B, C, and D are incorrect because collecting three early morning urine specimens, massaging the prostate, or collecting a routine urine specimen would not provide the specific separation of urethral and bladder urine required for this particular test.

Correct Answer: C

Rationale: The correct answer is C: Fat-soluble vitamins. Neomycin is known to interfere with the absorption of fat-soluble vitamins. This is because neomycin can disrupt the normal gut flora responsible for the absorption of these vitamins. Choices A, B, and D are incorrect because neomycin primarily affects the absorption of fat-soluble vitamins, not minerals, proteins, amino acids, or water-soluble vitamins.
