Correct Answer: D

Rationale: The correct answer is D: Subclavian veins. Lymph returns to the blood through the subclavian veins because they receive lymphatic drainage from the thoracic duct and right lymphatic duct. Lymphatic vessels merge into lymphatic ducts, which empty into the subclavian veins, allowing lymph to re-enter the bloodstream. The carotid arteries (A) carry oxygen-rich blood to the brain, the aorta (C) is the main artery of the body carrying oxygenated blood from the heart, and the inferior vena cava (B) returns deoxygenated blood from the lower body to the heart. Therefore, choices A, B, and C are incorrect as they are not involved in the return of lymph to the blood.

Correct Answer: A

Rationale: The correct answer is A: It is associated with stages 1 and 2 hypertension. Smoking is a major risk factor for developing hypertension, especially stages 1 and 2. Nicotine in cigarettes can lead to vasoconstriction, increased heart rate, and overall elevated blood pressure. This information is crucial for patients to understand the direct impact of smoking on their blood pressure levels. Choice B is incorrect because smoking does indeed affect BP regulation by causing vasoconstriction and elevated heart rate. Choice C is incorrect as smoking actually causes vasoconstriction rather than vasodilation. Choice D is incorrect because smoking does lead to sustained elevation of blood pressure, especially in the long term.

Correct Answer: C

Rationale: The correct answer is C: "You may feel a burning sensation when the dye is injected." This is important to include in preprocedure teaching for carotid angiography because it prepares the patient for a common sensation they may experience during the procedure. Providing this information helps manage expectations and reduce anxiety. Choice A is incorrect because carotid angiography is typically done with the patient awake. Choice B is incorrect as carotid angiography usually takes around 30-60 minutes. Choice D is incorrect because there can be complications associated with carotid angiography, such as allergic reactions or damage to blood vessels.

Correct Answer: D

Rationale: The correct answer is D because a normal corneal light reflex involves light being reflected at the same spot in both eyes. This indicates that both eyes are aligned properly and focusing light in the same direction. Choice A is incorrect because it refers to accommodation, not the corneal light reflex. Choice B is incorrect as convergence is related to eye movement, not the corneal light reflex. Choice C is incorrect as pupil constriction in response to light is known as the pupillary light reflex, not the corneal light reflex.

Correct Answer: C

Rationale: The correct answer is C: Health promotion. The nurse wrote a diagnosis of Readiness for enhanced urinary elimination, which indicates the patient's willingness to improve their urinary elimination abilities. Health promotion diagnoses focus on improving the client's well-being and enhancing their health potential. In this scenario, the patient's desire to learn self-catheterization aligns with health promotion as it involves empowering the patient to take an active role in their care. Choice A (Risk) is incorrect because the patient is not currently at risk for urinary elimination issues, but rather seeking to enhance their abilities. Choice B (Problem focused) is incorrect as the diagnosis is not about addressing a current problem but rather focusing on potential improvement. Choice D (Collaborative problem) is incorrect as it does not involve collaboration between healthcare providers but rather focuses on the patient's readiness and willingness to enhance their own health outcomes.
