Correct Answer: B

Rationale: The correct answer is B: Acute myocardial infarction (MI) is the most common cause of cardiogenic shock. During an MI, there is significant damage to the heart muscle, leading to a decrease in cardiac output and subsequent shock. This results in inadequate tissue perfusion and oxygen delivery. Choices A, C, and D are incorrect because decreased hemoglobin level (A) may lead to anemia but is not the most common cause of cardiogenic shock. Hypotension (C) is a symptom of shock, not the cause. Coronary artery disease (D) is a risk factor for MI but not the direct cause of cardiogenic shock.

Correct Answer: A

Rationale: The correct answer is A: Amoxicillin. Amoxicillin is the first-line treatment for GAS pharyngitis due to its effectiveness against Streptococcus bacteria. It is a penicillin-class antibiotic recommended by guidelines. Azithromycin is an alternative for patients allergic to penicillin. Cephalexin is not the first-line choice for GAS. Clindamycin is reserved for patients allergic to both penicillin and macrolides.

Correct Answer: C

Rationale: The correct answer is C: Systematic sampling. Nurse Sandy is adopting systematic sampling by selecting every third patient with MI after a random start. This method ensures equal chance of selection for each patient and maintains randomness. In contrast, simple random sampling (A) entails each patient having an equal chance of being selected independently. Stratified sampling (B) divides patients into groups based on certain characteristics, which is not the case here. Cluster sampling (D) involves grouping patients and selecting entire groups, which is different from the individual selection in this scenario.

Correct Answer: D

Rationale: The correct immediate action for the nurse is to notify the anesthesia provider immediately (Option D). This is crucial because a sudden change in the patient's level of consciousness during surgery could indicate a serious issue related to anesthesia administration. Notifying the anesthesia provider promptly allows for quick assessment and intervention to address the underlying cause, potentially preventing complications or even saving the patient's life. Administering a reversal agent (Option A) without proper evaluation by the anesthesia provider could be dangerous. Documenting the change in the patient's chart (Option B) is important but not the most immediate action. Checking the patient's vital signs (Option C) is also important but may not provide immediate insight into the cause of the change in consciousness.

Correct Answer: B

Rationale: The correct answer is B because an empowered nurse feels in control and valued, leading to job satisfaction. Enthusiasm shows motivation and engagement with their work. Being ethical indicates a commitment to moral principles, contributing to a sense of fulfillment. Choice A is incorrect as competitiveness and self-centeredness do not necessarily equate to job satisfaction. Euphoria may not be a sustainable indicator of satisfaction. Choice C is incorrect because being a loner and egoistic are not traits associated with job satisfaction. Reactivity may suggest a lack of control or frustration. Choice D is incorrect as being outgoing and competitive might not directly translate to job satisfaction. Sensitivity alone does not guarantee satisfaction in the workplace.
