A patient presents with well-demarcated, erythematous plaques with silvery scales on the trunk and extensor surfaces of the limbs. The patient reports a family history of similar skin lesions. Which of the following conditions is most likely responsible for this presentation?

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: A

Rationale: The patient is exhibiting signs and symptoms of alcohol withdrawal, such as tremors, diaphoresis, hyperactivity, elevated blood pressure, and tachycardia. Lorazepam, which is a benzodiazepine, is commonly used to manage alcohol withdrawal symptoms. It helps alleviate symptoms such as anxiety, agitation, tremors, and seizures by acting on the same brain receptors affected by alcohol. It has sedative, anxiolytic, and anticonvulsant properties which can help stabilize the patient and prevent potential complications of alcohol withdrawal, such as seizures. Haloperidol is an antipsychotic medication used for conditions like schizophrenia and acute psychosis; therefore, it would not be appropriate for alcohol withdrawal. Naloxone is used to reverse opioid overdose, and Benztropin is used to treat Parkinson's disease and extrapyramidal symptoms, so they are not indicated for alcohol

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: A

Rationale: The liver is responsible for secreting bile, which aids in the emulsification and digestion of fats. Bile is produced by the liver and is stored and concentrated in the gallbladder before being released into the small intestine to help with the breakdown of fats during the digestion process. The gallbladder functions as a storage organ for bile produced by the liver. The pancreas secretes digestive enzymes and bicarbonate to aid in the digestion process, while the spleen is mainly involved in immune function and blood storage.

Correct Answer: D

Rationale: The diagnosis of gestational diabetes mellitus (GDM) is typically confirmed through an oral glucose tolerance test (OGTT) during pregnancy. In GDM, the 2-hour plasma glucose level during the OGTT is equal to or greater than 140 mg/dL. This finding is characteristic of GDM and distinguishes it from other types of diabetes. Fasting blood glucose ≥126 mg/dL is diagnostic of diabetes mellitus outside of pregnancy, not specifically GDM. Random plasma glucose ≥200 mg/dL is indicative of uncontrolled diabetes in general. Hemoglobin A1c (HbA1c) ≥6.5% is used for diagnosing diabetes outside of pregnancy and is not specific to GDM.

Correct Answer: E

Rationale: All of the statements (A-D) are true when discussing the testing of vision in infants and children separately from testing in adults. However, statement E is NOT true. The course of visual and cognitive development MUST be taken into account in evaluating infants and children's visual abilities. It is crucial to consider the stage of development a child is in when evaluating their vision, as their visual abilities can change rapidly during early childhood. Ignoring the course of development could lead to incorrect assessments and misunderstandings about the child's visual capabilities.

Correct Answer: D

Rationale: The presentation described, including a well-demarcated, hyperpigmented patch with irregular borders, asymmetric color distribution, and increase in size over a short period, is concerning for melanoma. Melanoma is a type of skin cancer that arises from melanocytes, the cells that produce pigment in the skin. The irregular borders, color variation, and growth over time are classic signs of melanoma. Melanomas are potentially dangerous and should be evaluated promptly by a healthcare provider for proper diagnosis and treatment. It is important to distinguish melanoma from other benign lesions like melanocytic nevus (mole), lentigo simplex, and seborrheic keratosis, as early detection and treatment of melanoma can significantly impact patient outcomes.

Correct Answer: D

Rationale: The most appropriate diagnostic examination to confirm the incidence of hypertension among residents is blood pressure (BP) monitoring. Hypertension is defined by elevated blood pressure readings consistently measured over time. Monitoring of blood pressure is essential for diagnosing hypertension and determining the severity of the condition. Chest x-ray, ultrasound, and electrocardiogram are not specific tests for diagnosing hypertension. While these tests may be useful in assessing potential complications or causes of hypertension, they do not directly confirm the presence of high blood pressure. Regular BP monitoring with the use of a sphygmomanometer or automated blood pressure device is crucial in diagnosing and managing hypertension.

Correct Answer: C

Rationale: Choosing option C, asking the patient about their cultural beliefs and preferences related to pain, demonstrates cultural competence in pain assessment. Pain experiences can vary greatly across different cultures, and a patient's cultural background can influence how they perceive and express pain. By inquiring about the patient's cultural beliefs and preferences, the nurse can gain a better understanding of the patient's perspective on pain. This information is crucial for providing individualized and culturally sensitive pain management interventions. It also shows respect for the patient's unique cultural background and helps build a trusting and collaborative relationship between the nurse and the patient.
