Correct Answer: B

Rationale: The correct answer is B: Nausea and vomiting. Chemotherapy commonly causes gastrointestinal side effects, such as nausea and vomiting, due to its impact on rapidly dividing cells in the digestive tract. This adverse effect can significantly impact a patient's quality of life and adherence to treatment. Pruritis (A), itching, is less common and usually not a primary side effect of chemotherapy. Altered glucose metabolism (C) is a potential effect of some chemotherapeutic agents but is not the most common adverse effect. Confusion (D) is not typically associated with chemotherapy and is more commonly seen with other medications or medical conditions.

Correct Answer: B

Rationale: The nurse sitting at the patient's bedside is using the personal zone of personal space, which ranges from 18 inches to 4 feet. This distance allows for a close interaction suitable for taking a nursing history while maintaining a professional yet personal connection. The socio-consultative zone (A) is 4-12 feet, more appropriate for professional interactions. The intimate zone (C) is 0-18 inches, too close for an initial nursing history. The public zone (D) is 12 feet or more, too distant for a personal conversation.

Correct Answer: D

Rationale: The correct answer is D: Labyrinthitis. This condition presents with sudden onset vertigo, nausea, vomiting, tinnitus, and hearing loss, which are all symptoms described by the patient. Labyrinthitis is commonly caused by a viral infection affecting the inner ear, leading to inflammation of the labyrinth. This inflammation disrupts the balance and hearing functions of the inner ear, resulting in the symptoms mentioned. A: Ossiculitis involves inflammation of the middle ear bones, typically causing conductive hearing loss, not the sudden onset of vertigo and other symptoms described. B: Mnire's disease is characterized by recurrent episodes of vertigo, tinnitus, and hearing loss, but it typically does not present with sudden onset incapacitating vertigo. C: Ototoxicity is caused by exposure to certain medications or chemicals that damage the inner ear structures, leading to hearing loss. While hearing loss is a symptom, the sudden onset of vertigo is not typically associated with ototoxicity.

Correct Answer: B

Rationale: The correct answer is B: Diarrhea. In stage 3 HIV, gastrointestinal issues are common due to weakened immune system. Diarrhea can lead to dehydration and electrolyte imbalances, making it the priority nursing diagnosis. Acute Abdominal Pain (A) may be a symptom but not the priority. Bowel Incontinence (C) and Constipation (D) are less likely in stage 3 HIV.

Correct Answer: B

Rationale: Interdisciplinary collaboration involves clinicians from different backgrounds integrating their separate plans of care, ensuring a holistic approach to patient care. This fosters a comprehensive understanding of the patient's needs and individualized care. In contrast, multidisciplinary practice involves clinicians working independently without integrating their plans, potentially leading to fragmented care. Choice A is incorrect as interdisciplinary collaboration does have a team leader to coordinate and facilitate communication among team members. Choice C is incorrect because while communication and cooperation are essential in interdisciplinary collaboration, the key distinction is the integration of different perspectives and plans of care. Choice D is incorrect as interdisciplinary collaboration goes beyond just medical expertise and patient preference, involving professionals from various disciplines working together to address all aspects of patient care.
