Correct Answer: A

Rationale: In the case of a woman in active labor with placenta previa, the priority nursing intervention is to prepare for an immediate cesarean section. Placenta previa is a condition in which the placenta covers part or all of the cervix, which can lead to severe bleeding during labor and delivery. The risk of hemorrhage is significant, making a cesarean section the safest option for both the mother and the baby in this situation. It is crucial to act promptly to prevent complications and ensure the well-being of both the mother and the baby. Administering intravenous oxytocin to augment labor or inserting a Foley catheter to monitor urine output would not address the immediate risk of hemorrhage associated with placenta previa. Implementing bed rest and continuous fetal monitoring may be part of the overall care plan but not the priority intervention in this urgent situation.

Correct Answer: B

Rationale: A vegetative state, now more commonly referred to as unresponsive wakefulness syndrome, describes a condition where the patient is awake but with no awareness of themselves or their surroundings. This state usually follows a severe brain injury, such as traumatic brain injury. Patients in a vegetative state may have sleep-wake cycles, open their eyes, and even exhibit reflex movements, but they do not demonstrate any meaningful interaction with the environment. Differentiating between coma and vegetative state is important, as coma implies a complete lack of consciousness, while patients in a vegetative state have preserved wakefulness without awareness. Minimally conscious state (choice C) refers to a condition where there are some minimal signs of awareness or purposeful interaction, making it a different state than the one described in the scenario. Locked-in syndrome (choice D) is a condition where the patient is conscious and aware but unable to move or communicate due to paralysis, which is not consistent

Correct Answer: D

Rationale: Demerol (meperidine hydrochloride) is an opioid analgesic commonly used as a preoperative medication to decrease intra-operative anesthetic requirements and provide analgesia. Opioids like Demerol act on the central nervous system to reduce pain sensations, making it an effective choice for preoperative pain management. This can help decrease the amount of anesthesia needed during surgery, leading to better pain control and overall patient comfort during and after the procedure. Celebrex, acetaminophen, and ibuprofen are also used for pain management, but they do not have the same potency and mechanism of action as opioids like Demerol for reducing intra-operative anesthetic requirements.

Correct Answer: A

Rationale: Troponin is the most specific cardiac biomarker for myocardial injury. Troponin I and Troponin T are proteins released into the bloodstream when there is damage to the heart muscle, making them highly indicative of myocardial infarction. Troponin levels rise within a few hours of cardiac injury, peak within 24-48 hours, and can remain elevated for up to 2 weeks. Troponin is considered the gold standard biomarker for the diagnosis of acute myocardial infarction due to its high specificity and sensitivity for cardiac injury. In contrast, Creatine kinase-MB (CK-MB) and myoglobin are also used in diagnosing myocardial infarction but are less specific than troponin. Brain natriuretic peptide (BNP) is primarily used in heart failure diagnosis and management, and its levels are not specific to myocardial injury.

Correct Answer: C

Rationale: A Likert Scale is typically used to measure the degree of agreement or disagreement with a set of statements or questions. Respondents are asked to indicate their level of agreement or disagreement using a scale that ranges from, for example, "strongly agree" to "strongly disagree". This makes it a suitable tool for assessing the degree of agreement and disagreement among individuals on various topics or statements. While a Likert Scale can potentially measure other constructs such as satisfaction or acceptance, its primary purpose and most common application involve determining the degree of agreement and disagreement.
