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: B

Rationale: Administering ice packs to the perineum is the priority nursing intervention to provide relief for perineal pain and discomfort in a postpartum client. Ice packs help to reduce swelling and inflammation in the perineal area, which can help alleviate pain. It is a safe and effective method to provide immediate relief and promote comfort for the client. Other interventions such as encouraging ambulation, administering analgesics, and recommending warm sitz baths can also be beneficial, but in the initial management of perineal pain, ice packs are the most appropriate choice.

Correct Answer: B

Rationale: In the community setting, the essential record about the patient is the patient's chart. This chart contains all important information about the patient, including medical history, treatment plans, medications, progress notes, and any other pertinent information related to the patient's care. It serves as a crucial document for healthcare providers to track and monitor the patient's health status, facilitate communication among team members, ensure continuity of care, and make informed clinical decisions. The patient's chart is a comprehensive and centralized source of information that guides the delivery of quality care in the community setting.

Correct Answer: D

Rationale: Transcription errors are typically associated with issues such as illegible handwriting, misinterpretation of directions, and the use of unapproved abbreviations. However, the wrong route of medication administration is not specifically related to transcription errors but rather falls under the category of medication administration errors. Administering medication via the wrong route can lead to serious consequences for the patient and is a separate issue from the act of transcribing doctor's orders.

Correct Answer: B

Rationale: The presentation of a patient with diabetes mellitus showing symptoms of polyuria, polydipsia, nocturia, and fatigue along with laboratory findings of hyperglycemia, glycosuria, and ketonuria is indicative of diabetic ketoacidosis (DKA). DKA is a serious complication of diabetes characterized by hyperglycemia, metabolic acidosis, and ketosis. The increased glucose levels lead to glycosuria, causing osmotic diuresis resulting in polyuria, polydipsia, and nocturia. The body starts breaking down fats for energy in the absence of sufficient insulin, leading to the production of ketones causing ketonuria. The patient may also experience fatigue due to the metabolic abnormalities present in DKA.
