A patient presents with acute onset of severe vertigo, nausea, vomiting, and nystagmus. Symptoms are worsened with head movement. Which of the following neurological conditions is most likely responsible for these symptoms?

Correct Answer: B

Rationale: Vestibular neuritis is a condition characterized by the acute onset of severe vertigo, nausea, vomiting, and nystagmus. These symptoms are typically worsened by head movement. Vestibular neuritis is caused by inflammation of the vestibular nerve, which plays a key role in balance and spatial orientation. The classic presentation of these symptoms, along with the absence of hearing loss (which is seen in labyrinthitis), points towards vestibular neuritis as the most likely cause in this scenario. Meniere's disease presents with recurrent episodes of vertigo, hearing loss, tinnitus, and sensation of fullness in the ear. Benign paroxysmal positional vertigo (BPPV) is characterized by brief episodes of vertigo triggered by changes in head position.

Correct Answer: C

Rationale: The salivary glands are responsible for the production of saliva, which aids in lubricating the oral cavity and initiating the digestion of carbohydrates. Saliva contains enzymes that begin the digestive process by breaking down carbohydrates into simpler sugars. The liver is involved in the production of bile, which aids in the digestion and absorption of fats. The gallbladder stores bile produced by the liver, which is released into the small intestine. The pancreas produces digestive enzymes that are released into the small intestine to aid in the digestion of proteins, fats, and carbohydrates.

Correct Answer: B

Rationale: When a patient with a suspected spinal injury is found unconscious, the priority action is to secure the airway without jeopardizing the cervical spine. A jaw thrust maneuver is the appropriate technique to open the airway in this situation because it allows for the maintenance of neutral alignment of the cervical spine while ensuring proper ventilation. Moving the patient to a flat surface or applying a cervical collar could potentially worsen the spinal injury if not done correctly, and checking for responsiveness should only be done after ensuring a patent airway. Therefore, the safest and most effective initial action is to perform a jaw thrust maneuver to establish a clear airway.

Correct Answer: C

Rationale: The patient's presentation of thyroid nodule with compression symptoms like difficulty swallowing and breathing, along with fine-needle aspiration biopsy showing a follicular pattern and colloid-filled spaces, is highly suggestive of a follicular adenoma. Follicular adenomas are benign thyroid tumors that can cause compression symptoms due to their growth and size, leading to pressure on surrounding structures in the neck area. The presence of colloid-filled spaces in the biopsy is characteristic of follicular adenomas.

Correct Answer: D

Rationale: When someone is bitten by a dog, the most important first aid step is to wash the wound thoroughly with running water. This helps to remove any dirt or bacteria from the wound, reducing the risk of infection. Washing the wound with garlic (choice A) is not recommended as it can irritate the skin and may not effectively clean the wound. Feeding the dog (choice B) is not relevant to treating the bite wound. Bleeding the bitten area (choice C) is also not necessary and can actually increase the risk of infection. Therefore, the best advice the nurse should give in case of a dog bite is to wash the wound thoroughly with running water.

Correct Answer: D

Rationale: Public Health Nursing is a specialized field of nursing that focuses on promoting and protecting the health of populations and communities rather than individuals. One of the key principles of Public Health Nursing is the emphasis on health promotion and disease prevention strategies. This involves educating and empowering individuals, families, and communities to adopt healthy behaviors and lifestyles in order to prevent illness and improve overall well-being. Public Health Nurses work to address the root causes of health disparities and advocate for policies and programs that promote the health of entire populations. While providing care to sick individuals may be a component of Public Health Nursing, the primary focus is on preventing illness and promoting health at the community level.

Correct Answer: B

Rationale: Delegation by succession involves passing on responsibility and authority to a designated successor when the delegator is temporarily unavailable. In this scenario, the unit manager is planning to take her regular official business leave and has recommended her assistant unit manager to assume her position during her absence. This act follows the principle of succession, where the deputy or next in line is entrusted with the duties and decision-making power of the manager. This ensures a smooth transition of responsibilities and allows the operations to continue efficiently in the manager's absence.

Correct Answer: C

Rationale: Chest pain, dyspnea, hypotension, and ST-segment elevation on an ECG in the inferior leads are classic signs of an acute myocardial infarction (MI). An acute MI occurs when there is a sudden blockage of blood flow to a part of the heart muscle, leading to tissue damage. This causes symptoms such as chest pain due to ischemia, dyspnea due to heart failure, and hypotension due to poor cardiac output. The ST-segment elevation seen on the ECG is indicative of significant myocardial injury. Prompt diagnosis and management are crucial in acute MI to prevent further complications and to minimize damage to the heart muscle. It is important to differentiate an acute MI from stable or unstable angina or other cardiovascular disorders, as the management and prognosis vary significantly.

Correct Answer: A

Rationale: For a preschooler, it is recommended that they get more than 8 hours of sleep each day. Adequate sleep is crucial for their physical development, overall health, and cognitive function. Preschoolers typically need around 10-13 hours of sleep per day to support their growth and development. Getting less than the recommended amount of sleep can lead to issues such as behavioral problems, difficulty concentrating, and poor physical development. Therefore, ensuring that a preschooler gets enough sleep is vital for their physical well-being.
