Residents with the abbreviation _____ on their diet cards cannot have anything to eat or drink by mouth.

Correct Answer: A

Rationale: The correct answer is A: NPO. NPO stands for "nil per os," which means nothing by mouth. This abbreviation is used to indicate that a patient should not have anything to eat or drink orally. It is crucial in situations where oral intake needs to be restricted for medical reasons. Explanation for why the other choices are incorrect: B: NCS - NCS stands for "no concentrated sweets" and relates to dietary restrictions for patients with diabetes. It does not indicate complete restriction from oral intake. C: LCS - LCS stands for "low-calorie sweeteners" and is related to artificial sweeteners. It does not indicate complete restriction from oral intake. D: ADA - ADA stands for American Diabetes Association and is an organization related to diabetes management. It does not indicate any restriction from oral intake.

Correct Answer: B

Rationale: The correct answer is B (30 minutes) as it allows enough time for fluids to be absorbed and reach the bladder, prompting the need for voiding. Waiting only 10 minutes (A) may not give the body enough time to process fluids. Waiting longer than 30 minutes (C and D) may result in discomfort or accidents. Optimal timing ensures the resident's comfort and promotes continence.

Correct Answer: D

Rationale: Certainly! The correct answer is D because applying heat to the body dilates blood vessels, increasing blood flow and facilitating the movement of oxygen and nutrients into the tissues, promoting healing and reducing muscle tension. Choice A is incorrect because heat can dilate blood vessels, increasing bleeding. Choice B is incorrect as heat actually helps to relax muscles, reducing tension. Choice C is incorrect as heat causes vasodilation, increasing blood flow rather than decreasing it.

Correct Answer: C

Rationale: The correct answer is C: Failure to finish the medication makes the person more likely to spread the disease to others. This is because TB is a contagious disease, and incomplete treatment can lead to drug-resistant strains, making the person more infectious. Choosing option A is incorrect because the cost of medication is not the primary reason for completing the treatment. Option B is incorrect as Medicare funding is not directly linked to individual patient adherence. Option D is incorrect as the main concern with not completing TB medication is the risk of treatment failure and spreading the disease, not the impact on the musculoskeletal system.

Correct Answer: D

Rationale: The correct answer is D because the nervous system is responsible for sensing stimuli from the external environment and interpreting that information. This process involves receptors that detect various stimuli such as touch, taste, smell, sound, and sight. The sensory information is then transmitted to the brain for processing and interpretation. This function allows the body to respond appropriately to changes in the environment, ensuring survival and adaptation. Choices A, B, and C are incorrect: A: Giving the body shape and structure is primarily the role of the skeletal system. B: Providing a protective covering to the body is the function of the integumentary system (skin). C: Producing antibodies and infection-fighting blood cells is the role of the immune system, not the nervous system.
