A patient presents with chest pain that worsens with exertion and improves with rest. An electrocardiogram (ECG) shows ST-segment depression. Which cardiovascular disorder is most likely responsible for these symptoms?

Correct Answer: A

Rationale: The patient is presenting with chest pain that worsens with exertion and improves with rest, which is characteristic of stable angina. Additionally, ST-segment depression on ECG is a common finding in patients with stable angina. Stable angina is typically caused by coronary artery disease, which leads to partial obstruction of the coronary arteries resulting in inadequate blood flow to the heart muscle during periods of increased demand (such as exertion). The chest pain is usually predictable and reproducible, occurring with similar intensity and duration during episodes of exertion. Rest or nitroglycerin can help relieve the symptoms by increasing coronary blood flow. It is important to differentiate stable angina from unstable angina and acute myocardial infarction, which have different management and prognostic implications.

Correct Answer: C

Rationale: Intracerebral hemorrhage occurs when there is bleeding directly into the brain tissue, often due to conditions such as hypertension or vascular malformations. The sudden-onset severe headache, altered mental status, and focal neurological deficits described in the patient are typical symptoms of an intracerebral hemorrhage. The location of the hemorrhagic lesion within the right basal ganglia corresponds to the clinical presentation. Ischemic stroke, subarachnoid hemorrhage, and transient ischemic attack (TIA) typically have different presentations and imaging findings compared to an intracerebral hemorrhage. Therefore, in this scenario, intracerebral hemorrhage is the most likely cause of the patient's symptoms.

Correct Answer: A

Rationale: Aplastic anemia is a condition characterized by a reduction in the number of all three blood cell types: red blood cells, white blood cells, and platelets. The patient's presentation of bone pain, fatigue, frequent infections, pancytopenia (decreased counts of all blood cell types), hypocellular bone marrow (reduced cellularity in the bone marrow), and absence of reticulocytes is indicative of aplastic anemia.

Correct Answer: A

Rationale: The nurse should inform the public that rabies can be prevented. This is an extremely important piece of information to help raise awareness about the disease and promote preventive measures such as timely vaccination of both animals and humans. Rabies is a deadly viral infection that affects the central nervous system, and prevention through vaccination is highly effective in controlling its spread. By emphasizing the preventability of rabies, the nurse can educate the public on the importance of taking proactive steps to avoid contracting the disease.

Correct Answer: C

Rationale: If Jose is complaining of dyspnea despite continuous oxygen therapy, the nurse's initial intervention should be to assess the patency of the tubing delivering the oxygen. A blockage in the tubing could restrict the flow of oxygen to the patient, leading to inadequate oxygen delivery and worsening dyspnea. By ensuring the tubing is clear and functioning properly, the nurse can address a potential issue with oxygen delivery before considering other interventions like giving PRN medication or involving the physician. Re-assessing the patient would also be important after ensuring the tubing's patency to evaluate the effectiveness of the intervention.

Correct Answer: A

Rationale: The correct practice in this situation would be to have a dedicated fire extinguisher in every strategic location throughout the hospital. Having fire extinguishers readily available in key areas ensures that they can be accessed quickly in case of a fire emergency. Placing one fire extinguisher between two units may not be sufficient as it may not be easily accessible in the event of a fire. Fire extinguishers should not be replaced with fire sensors as these serve different functions. Additionally, borrowing fire extinguishers may not be a safe or reliable practice, as they should be properly maintained and placed according to safety standards. Therefore, having dedicated fire extinguishers in every strategic location is the best practice to ensure the safety and well-being of individuals in the hospital.

Correct Answer: B

Rationale: The presentation of a pruritic, erythematous rash with edematous plaques and vesicles on the hands and fingers in a patient with a history of exposure to detergents and frequent hand washing is most indicative of contact dermatitis. Contact dermatitis can be caused by direct contact with irritants such as detergents or chemicals, leading to skin irritation and inflammation. In this case, the history of exposure to detergents and hand washing suggests that the rash is likely due to irritant contact dermatitis. Atopic dermatitis, psoriasis, and pityriasis rosea do not typically present with the same pattern of rash in response to irritant exposure.

Correct Answer: B

Rationale: Sunken fontanels are one of the earliest signs of dehydration in infants. Fontanels are soft spots on an infant's head where the skull bones have not yet fused together. If a baby's fontanel appears sunken, it indicates that the baby is likely dehydrated. This occurs because when there is a lack of fluid in the body, the soft spots on the head will appear depressed or sunken. It is crucial for Nurse Juvy to closely monitor the fontanels of Baby Sharon, as identifying dehydration early is essential for prompt intervention and preventing complications.

Correct Answer: A

Rationale: Prolonged rupture of membranes (>24 hours) increases the risk of intrauterine infection for both the mother and the fetus. When the amniotic sac has been ruptured for an extended period, there is a higher likelihood of bacteria entering the uterus, leading to chorioamnionitis (inflammation of the fetal membranes due to infection). Intrauterine infection can be dangerous for both the mother and fetus, potentially causing sepsis, preterm labor, and other complications. Therefore, it is crucial for the nurse to assess for signs and symptoms of infection in both the mother and fetus when managing a woman in active labor with prolonged rupture of membranes.
