Following hypophysectomy, patients require extensive teaching regarding this major alteration in their lifestyle

Correct Answer: B

Rationale: The correct answer is B (Lifetime dependency on hormone replacement) because after hypophysectomy (removal of the pituitary gland), patients will no longer produce essential hormones like growth hormone, thyroid-stimulating hormone, etc. Therefore, they will require lifelong hormone replacement therapy to maintain normal bodily functions. A: Abnormal distribution of body hair is not directly related to hypophysectomy. C: While fluid intake may be important post-surgery, it is not the primary focus of teaching. D: There is typically no need for repeat surgical procedures after a hypophysectomy, as it is a one-time surgery to address specific issues. In summary, choice B is correct as it directly addresses the long-term implications of the surgery on hormone production and the need for replacement therapy, while the other choices are not directly relevant to the post-operative care of hypophysectomy patients.

Correct Answer: C

Rationale: Step-by-step rationale: 1. The cranial nerve responsible for facial expression is CN VII, the facial nerve. 2. When a neurologist asks a patient to smile, they are testing the function of CN VII. 3. CN II (optic nerve) is responsible for vision, not facial expression. 4. CN X (vagus nerve) is responsible for various functions like heart rate and digestion, not facial expression. 5. CN XI (accessory nerve) is responsible for shoulder movement, not facial expression. Summary: Testing a patient's ability to smile involves assessing the function of CN VII, the facial nerve. Choices A, B, and D are incorrect as they are associated with different functions and not responsible for controlling facial muscles.

Correct Answer: D

Rationale: Correct Answer: D - Lubricating eye drops Rationale: Lubricating eye drops help prevent complications such as corneal abrasions in patients with Bell's Palsy by keeping the eye moist and preventing dryness. Bell's Palsy can cause difficulty in closing the eye properly, leading to dryness and potential damage to the cornea. Using lubricating eye drops helps maintain eye health. Summary of Incorrect Choices: A: Megavitamin therapy - Not directly related to preventing complications in Bell's Palsy. B: Application of ice to the affected area - Ice may not address eye dryness or prevent corneal abrasions. C: Elastic bandages - Not relevant to preventing complications associated with Bell's Palsy.

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. Chorea is a hallmark feature of Huntington's disease, caused by damage to the basal ganglia. Intellectual decline includes cognitive impairments such as memory loss and executive dysfunction. Emotional disturbances involve mood swings, irritability, and apathy. Therefore, all three manifestations are commonly seen in individuals with Huntington's disease, making D the correct choice. Choices A, B, and C are incorrect individually because they do not encompass all the key clinical features of Huntington's disease.

Correct Answer: C

Rationale: The correct answer is C because in myasthenia gravis, which is characterized by muscle weakness and fatigue, the administration of edrophonium will temporarily improve muscle strength due to increased availability of acetylcholine at the neuromuscular junction. This improvement should be noted within 30 to 60 seconds after the administration of the medication. Choice A is incorrect because joint pain is not a typical response to edrophonium in the context of myasthenia gravis. Choice B is incorrect because feelings of faintness, dizziness, hypotension, and flushing are more indicative of a cholinergic crisis, which occurs when too much edrophonium is administered. Choice D is incorrect because an increase in muscle strength post-edrophonium administration would not be expected in a client with myasthenia gravis.
