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.

Correct Answer: A

Rationale: Naloxone is a medication used to reverse the effects of an opioid overdose by binding to opioid receptors and displacing the opioids. Administering naloxone intravenously is the recommended intervention for managing a patient with a suspected opioid overdose as it can quickly reverse respiratory depression, sedation, and other effects of opioids. This intervention can be life-saving in cases of opioid overdose and is a critical step in the management of such patients. Providing respiratory support with bag-valve-mask ventilation may be necessary in addition to naloxone administration to ensure adequate oxygenation, but naloxone remains the primary intervention to reverse the effects of opioids. Encouraging the patient to drink fluids rapidly or administering benzodiazepines for sedation are not recommended interventions for managing a suspected opioid overdose.

Correct Answer: B

Rationale: The patient's presentation of well-demarcated, erythematous plaques with silvery scales on the trunk and extensor surfaces of the limbs is classic for psoriasis. Additionally, the family history of similar skin lesions further supports the diagnosis of psoriasis, as it is a condition with a genetic predisposition. Pityriasis rosea typically presents with a herald patch followed by oval, scaly lesions in a Christmas tree pattern. Erythema multiforme is characterized by target-like lesions. Lichen planus presents as purple, polygonal, flat-topped papules that may have fine white lines on their surface known as Wickham striae.

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: When a pregnant woman is diagnosed with preeclampsia, the focus of health care shifts to the individual woman herself. Preeclampsia is a serious condition that affects the health of the pregnant woman and her unborn child. The healthcare team will prioritize the care and treatment of the woman to ensure her well-being and safety. In this scenario, the emphasis is on providing personalized and targeted care to address the needs of the individual patient, rather than a broader focus on population groups, communities, or families.
