Correct Answer: A

Rationale: The nurse recommends regular monitoring of the patient's blood cholesterol levels to prevent complications from their heart disease. High levels of cholesterol can lead to the buildup of plaque in the arteries, increasing the risk of heart problems such as heart attacks and strokes. Monitoring cholesterol levels allows healthcare providers to assess the patient's risk and make appropriate recommendations for managing their heart disease. Regular monitoring can help track the effectiveness of lifestyle changes or medications in lowering cholesterol levels and reducing the risk of complications.

Correct Answer: D

Rationale: The clinical presentation of chest pain, dyspnea, and a friction rub heard on auscultation is suggestive of pericarditis. The diffuse ST-segment elevation seen on the electrocardiogram (ECG) is a classic finding in pericarditis, known as the "universal sign." In contrast, stable angina typically presents with chest pain on exertion that is relieved by rest or nitroglycerin, while unstable angina presents with chest pain at rest or with minimal exertion. Acute myocardial infarction would typically present with ST-segment elevation in specific leads correlating with the area of myocardial ischemia/infarction. However, in the context of diffuse ST-segment elevation and symptoms suggestive of inflammation (friction rub), the most likely diagnosis is pericarditis.

Correct Answer: C

Rationale: By endorsing a detergent product on a TV commercial wearing a mini skirt and a plunging neckline shirt, Ms. Sanchez is violating the code of ethics for nurses. The code of ethics for nurses includes provisions that promote professionalism, respect, and integrity in the nursing profession. As a new nursing graduate, Ms. Sanchez has a responsibility to uphold the dignity and reputation of the nursing profession, and endorsing a product in a manner that may compromise her professional image goes against these principles. Nurses are expected to maintain a professional appearance and behavior that reflects positively on the profession and does not undermine public trust in their abilities as healthcare providers. Therefore, Ms. Sanchez's actions in this scenario are in violation of the code of ethics for nurses.

Correct Answer: A

Rationale: The clinical presentation of recurrent fever, sore throat, cervical lymphadenopathy, leukocytosis with atypical lymphocytes, and positive heterophile antibody test (Monospot test) is highly indicative of infectious mononucleosis caused by the Epstein-Barr virus (EBV). EBV is a member of the herpesvirus family and is a common cause of infectious mononucleosis. The atypical lymphocytes seen on peripheral blood smear are reactive T lymphocytes responding to the EBV infection. The Monospot test detects heterophile antibodies produced in response to EBV infection.

Correct Answer: D

Rationale: Bronze baby syndrome is the term used to describe the transient discoloration of a baby's skin while undergoing phototherapy treatment for jaundice. This phenomenon typically occurs in preterm infants and is believed to be caused by the breakdown of bilirubin into colored pigments during phototherapy. The discoloration can range from a bronze or brownish color to a grayish-green hue. One key characteristic of bronze baby syndrome is that the discoloration is reversible once phototherapy is complete and does not indicate any underlying health concerns. It is important for healthcare providers to be aware of this phenomenon to avoid unnecessary interventions or alarm to the caregivers.
