The nurse is teaching a review class on the lymphatic system. A participant shows correct understanding of the material with which statement?

Correct Answer: B

Rationale: The correct answer is B: "The flow of lymph is slow, compared with that of the blood." Rationale: 1. Lymphatic vessels lack a central pump like the heart, which results in slower lymph flow compared to blood flow. 2. The slow movement allows for thorough filtration and immune surveillance within lymph nodes. 3. The statement reflects an accurate understanding of the physiological differences between the lymphatic and circulatory systems. Summary: A: Incorrect - Lymph flow is not propelled by the contraction of the heart; it is propelled by skeletal muscle contractions and respiratory movements. C: Incorrect - Lymph's main function is to collect excess tissue fluid and return it to the bloodstream, not to absorb lipids from the biliary tract. D: Incorrect - Lymph vessels do have one-way valves that prevent backflow, ensuring the proper direction of lymph flow.

Correct Answer: C

Rationale: The correct answer is C: Give the patient information about reduction of fat, cholesterol, and calories because he is overweight. Rationale: 1. BMI of 26.0 kg/m2 indicates the patient is overweight, not underweight (anorexic) (Choice A) or obese (Choice D). 2. Patient's concern about weight indicates the need for guidance on healthy habits. 3. Providing information on reducing fat, cholesterol, and calories aligns with addressing weight concerns. Incorrect Choices: A: Refer the patient to a nutritionist because he is anorexic - Incorrect because the patient is overweight, not anorexic. B: Reassure the patient that he has a normal body weight - Incorrect as BMI of 26.0 kg/m2 indicates overweight, not normal weight. D: Give the patient information about reduction of fat and cholesterol because he is obese - Incorrect as the patient is overweight, not obese.

Correct Answer: A

Rationale: The correct answer is A: Complete database. During the first visit for a checkup, a complete database is necessary to gather comprehensive information about the patient's medical history, current health status, family history, medications, allergies, and lifestyle factors. This type of data collection allows the healthcare provider to establish a baseline for the patient's health and identify any potential risks or issues. Choice B (Focused or problem-centered database) would not be appropriate for the first visit as it involves gathering information related to a specific health issue or concern, which may not capture all relevant information for a new patient. Choice C (Follow-up database) is used to track changes or progress over time for established patients, so it is not suitable for the initial visit. Choice D (Emergency database) is designed for urgent situations where quick access to critical information is needed, which is not the case for a routine checkup.

Correct Answer: B

Rationale: The correct answer is B: Nontherapeutic. This statement is nontherapeutic because it dismisses the client's feelings and concerns by invalidating them with a superficial reassurance. It does not address the client's emotions or provide meaningful support. Other choices are not applicable as only the therapeutic vs. nontherapeutic aspect is being evaluated here.

Correct Answer: A

Rationale: The correct answer is A: Posterior interosseous nerve. Compression of this nerve can mimic lateral epicondylitis due to similar symptoms like wrist and finger extension weakness. The other choices are incorrect because: B: Anterior interosseous nerve compression presents with different symptoms, C: Median nerve compression typically causes different symptoms like carpal tunnel syndrome, and D: C8/T1 nerve roots are associated with different conditions like thoracic outlet syndrome.
