You are conducting a cranial nerve assessment on a new patient. She cannot feel vibration of the tuning fork when the Weber test is performed. She exhibits a deficit of which cranial nerve?
- A. II
- B. III
- C. VI
- D. VIII
Correct Answer: D
Rationale: The Weber test assesses hearing and involves cranial nerve VIII (vestibulocochlear nerve). If the patient cannot feel vibration, it indicates a deficit in CN VIII. CN II (optic), CN III (oculomotor), and CN VI (abducens) are not involved in hearing.

What gland produces a secretion that causes fight-or-flight responses in effectors?
- A. adrenal medulla
- B. salivatory gland
- C. reproductive gland
- D. thymus
Correct Answer: A
Rationale: The correct answer is A: adrenal medulla. The adrenal medulla is part of the adrenal gland and secretes adrenaline and noradrenaline in response to stress, leading to fight-or-flight responses. The salivary gland produces saliva, the reproductive gland produces sex hormones, and the thymus produces T-cells for the immune system, none of which are related to fight-or-flight responses.
The nurse positions a client who is being treated for a fracture. Why should care be taken to position the client's joints in an anatomic alignment?

- B. To facilitate the lung expansion and prevent the pooling of secretions
- C. To prevent the escalation of the pain and swelling
- D. To prevent damage to the peripheral nerves and the blood vessels
Correct Answer: D

A patient recovering from an acute exacerbation of RA tells the nurse that she is too tired to bathe. What should the nurse do for this patient?

A patient with Guillain-Barré syndrome asks whether he is going to die as the paralysis spreads toward his chest. In responding to the patient, what should the nurse know to be able to answer this question?
- A. Patients who require ventilatory support almost always die.
- B. Death occurs when nerve damage affects the brain and meninges.
- C. Most patients with Guillain-Barré syndrome make a complete recovery.
- D. If death can be prevented, residual paralysis and sensory impairment are usually permanent.
Correct Answer: C
Rationale: Most patients recover fully, though some may have long-term deficits.
Which of the following is the causative agent of East African trypanosomiasis?
- A. Trypanosoma cruzi
- B. Trypanosoma vivax
- C. Trypanosoma brucei rhodanese
- D. Trypanosoma brucei gambiense
Correct Answer: C
Rationale: The correct answer is C: Trypanosoma brucei rhodanese. East African trypanosomiasis is caused by Trypanosoma brucei, specifically the subspecies Trypanosoma brucei rhodanese. This parasite is transmitted by tsetse flies and infects humans, causing sleeping sickness. Trypanosoma cruzi (Choice A) causes Chagas disease, not East African trypanosomiasis. Trypanosoma vivax (Choice B) causes a different form of animal trypanosomiasis. Trypanosoma brucei gambiense (Choice D) is responsible for West African trypanosomiasis, not the East African form. Therefore, the correct choice is C.
