A patient presents with chest pain that occurs during emotional stress and resolves spontaneously. An electrocardiogram (ECG) may show transient ST-segment elevation. Which cardiovascular disorder is most likely responsible for these symptoms?

Correct Answer: D

Rationale: Takotsubo cardiomyopathy, also known as stress-induced cardiomyopathy or broken heart syndrome, presents with symptoms similar to acute coronary syndrome, such as chest pain and ECG changes. In Takotsubo cardiomyopathy, chest pain typically occurs during emotional stress and resolves spontaneously, similar to the scenario described in the question. The ECG may show transient ST-segment elevation. This condition is characterized by a reversible left ventricular dysfunction that can mimic a myocardial infarction. Unlike stable angina (Choice A) and unstable angina (Choice B), Takotsubo cardiomyopathy is not related to coronary artery disease. Acute myocardial infarction (Choice C) typically presents with persistent ST-segment elevation on ECG and is caused by atherosclerotic plaque rupture leading to myocardial infarction, which is not consistent with the transient ST-segment elevation seen in

Correct Answer: C

Rationale: In this scenario, the action that violates a psychiatric patient's rights is option C, where staff members confiscated written letters done by patients addressed to the local newspaper. Patients have the right to communicate freely and express their thoughts and feelings through various means, such as letter-writing. Confiscating these letters is a violation of their rights to free expression and communication. It is essential to respect and uphold the rights of psychiatric patients, including their right to communicate with others.

Correct Answer: D

Rationale: Referring the client to a lactation consultant for specialized support should be prioritized to support successful breastfeeding in this situation. Breast augmentation surgery may impact milk production, let-down reflex, and proper latch due to alterations in breast tissue and nerve pathways. A lactation consultant can provide individualized guidance and support to address these specific challenges. Additionally, the consultant can assist in establishing a breastfeeding plan tailored to the client's unique needs, helping to optimize the breastfeeding experience for both the mother and the baby. It is crucial to seek expert assistance in navigating any potential difficulties that may arise from breastfeeding after breast augmentation to promote successful breastfeeding outcomes.

Correct Answer: B

Rationale: The research design being referred to in the question is an experimental design. An experimental study involves the manipulation of an independent variable, which is the intervention in this case, to determine its effect on a dependent variable. "Blinding" in research refers to the practice of withholding information about the intervention from certain individuals involved in the study, such as researchers, participants, or outcome assessors. Blinding is commonly used in experimental studies to reduce bias and ensure the integrity of the study results. This combination of intervention and blinding is a hallmark of experimental research designs.

Correct Answer: D

Rationale: Quality improvement focuses on proactive measures rather than reactive responses. The medical director would be more interested in establishing processes and systems that prevent issues from occurring in the first place, rather than just reacting to problems as they arise. Continuous improvement involves identifying problems, analyzing root causes, and implementing long-term solutions to prevent the issues from recurring. Therefore, reacting to correct or bad situations is not a characteristic of quality improvement that the medical director would prioritize.

Correct Answer: B

Rationale: Uterine hyperstimulation, also known as tachysystole, is a condition characterized by frequent and intense uterine contractions with minimal rest intervals. This can lead to maternal fatigue and decreased fetal oxygenation due to the insufficient time for the uterus to relax and refill with oxygenated blood between contractions. Uterine hyperstimulation can be caused by various factors such as excessive use of uterotonics (oxytocin or prostaglandins), improper labor induction techniques, or maternal conditions like previous uterine surgery. It is essential for the nurse to assess for signs of uterine hyperstimulation and take appropriate interventions to prevent potential complications for both the mother and the baby.

Correct Answer: A

Rationale: The healthcare team should prioritize administering lactulose or other ammonia-lowering agents to manage hepatic encephalopathy in a patient with acute liver failure. Hepatic encephalopathy is a neuropsychiatric syndrome that occurs in patients with liver dysfunction, leading to the accumulation of ammonia and other neurotoxic metabolites in the bloodstream. Lactulose works by acidifying the colon, which promotes the conversion of ammonia to ammonium, a less toxic form that can be excreted in the stool. By reducing the levels of ammonia, lactulose helps improve the neurological symptoms associated with hepatic encephalopathy.

Correct Answer: C

Rationale: A dental abscess is a condition characterized by inflammation and infection of the soft tissues surrounding the apex of a tooth root. This infection can result from untreated dental decay, trauma to the tooth, or periodontal disease. The abscess can cause pain, swelling, redness, and even pus formation. Treatment typically involves draining the abscess, removing the source of infection, and possibly prescribing antibiotics to address the infection. If left untreated, a dental abscess can lead to serious complications and spread to other parts of the body.

Correct Answer: C

Rationale: The nurse should prioritize checking the patency of the NG tube by aspirating gastric contents before initiating tube feeding. This is important to ensure that the NG tube is in the correct position and that it is functioning properly. By aspirating gastric contents, the nurse can confirm that the tube is in the stomach and not in the lungs or surrounding tissues. If no gastric contents are obtained upon aspiration, it may indicate that the tube is not properly placed or may be occluded, which would require further assessment and intervention before proceeding with tube feeding. Checking the patency of the NG tube is a crucial step in ensuring the safety and effectiveness of enteral nutrition delivery.
