Correct Answer: D

Rationale: The correct answer is D because Huntington's disease is a neurodegenerative disorder that presents with a triad of symptoms: abnormal involuntary movements (chorea), intellectual decline, and emotional disturbances. Abnormal involuntary movements are a hallmark feature, while cognitive decline and emotional disturbances are also commonly observed. Therefore, all three manifestations are typically present in individuals with Huntington's disease. Choices A, B, and C are incorrect because each of these symptoms alone does not encompass the full spectrum of clinical manifestations seen in Huntington's disease.

Correct Answer: A

Rationale: The correct answer is A, below 70mg/dl, for a hypoglycemic client. Hypoglycemia is defined as low blood glucose levels, typically below 70mg/dl. Symptoms of hypoglycemia include confusion, sweating, shakiness, and palpitations. Treating hypoglycemia involves providing the client with a fast-acting source of glucose to raise their blood sugar levels quickly. Choices B, C, and D are incorrect as they indicate normal or elevated blood glucose levels, which are not characteristic of hypoglycemia. It is crucial for the nurse to recognize and promptly address hypoglycemia to prevent potential complications.

Correct Answer: C

Rationale: The correct initial action for the nurse is to choose option C: Notify the physician. Increasing oxygen without a healthcare provider's order can be harmful, especially in COPD patients prone to retaining carbon dioxide. The nurse should communicate the situation to the physician to assess the client's condition and adjust the oxygen therapy appropriately. Option A is incorrect as it neglects the potential risks of high oxygen levels. Option B is incorrect as immediate decrease without proper assessment can be dangerous. Option D is not the priority when the client's oxygen therapy needs evaluation.

Correct Answer: A

Rationale: The correct answer is A: Otorrhea. Otorrhea refers to the discharge of fluid from the ear, indicating an abnormal finding of ear drainage. This term specifically describes the symptom of ear drainage, making it the most appropriate choice for documenting this finding. Otalgia (choice B) refers to ear pain, ototoxic (choice C) refers to substances that are harmful to the ear, and tinnitus (choice D) refers to ringing in the ears, none of which accurately describe ear drainage. Therefore, the correct choice is A as it specifically addresses the symptom of ear drainage.

Correct Answer: B

Rationale: The correct answer is B: "There is an increase in the intraocular pressure." Glaucoma is a group of eye conditions that damage the optic nerve due to increased pressure within the eye. High intraocular pressure is a key factor in the development of glaucoma. Choice A is incorrect because glaucoma is not associated with an increase in vitreous humor. Choice C is incorrect as glaucoma is not related to a decrease in aqueous humor. Choice D is incorrect because glaucoma is characterized by an increase, not a decrease, in intraocular pressure. Therefore, the most accurate description to explain glaucoma to a patient is the one that mentions the increase in intraocular pressure.
