A patient presents with chest pain that worsens with swallowing and is relieved by leaning forward. An electrocardiogram (ECG) shows diffuse ST-segment elevation. Which cardiovascular disorder is most likely responsible for these symptoms?
- A. Stable angina
- B. Unstable angina
- C. Acute myocardial infarction
- D. Pericarditis
Correct Answer: D
Rationale: The given clinical presentation of chest pain that worsens with swallowing and is relieved by leaning forward along with diffuse ST-segment elevation on an ECG is highly suggestive of pericarditis. Pericarditis is the inflammation of the pericardium, the thin sac surrounding the heart. The symptoms of pericarditis can mimic those of myocardial infarction (heart attack) but can also be differentiated by certain characteristics such as the described positional chest pain, which is worsened by swallowing and relieved by leaning forward.

A patient expresses concerns about the potential side effects of a prescribed medication. What is the nurse's best approach to address these concerns?
- A. Dismiss the patient's concerns and reassure them that side effects are unlikely.
- B. Provide the patient with accurate information about potential side effects and management strategies.
- C. Ignore the patient's concerns and focus solely on administering the medication.
- D. Tell the patient that side effects are common and unavoidable.
Correct Answer: B
Rationale: The nurse's best approach to address a patient's concerns about the potential side effects of a prescribed medication is to provide the patient with accurate information about potential side effects and management strategies. It is important for the nurse to acknowledge the patient's concerns, listen attentively, and offer clear explanations to help alleviate any fears or uncertainties. Providing accurate information can empower the patient to make informed decisions about their healthcare and feel more confident in taking the prescribed medication. Dismissing or ignoring the patient's concerns can lead to mistrust and non-adherence to the treatment plan. It is essential for the nurse to prioritize open communication and patient education to ensure the patient's well-being and compliance with the prescribed medication regimen.
A patient admitted to the ICU develops acute exacerbation of chronic heart failure (CHF) with pulmonary edema and respiratory distress. What intervention should the healthcare team prioritize to manage the patient's exacerbation?
- A. Administer intravenous loop diuretics for fluid removal.
- B. Initiate positive pressure ventilation for respiratory support.
- C. Perform emergent pericardiocentesis for tamponade relief.
- D. Recommend inotropic medications to improve myocardial contractility.
Correct Answer: B
Rationale: In this scenario, the patient is presenting with acute exacerbation of chronic heart failure (CHF) complicated by pulmonary edema and respiratory distress. The priority intervention for managing this exacerbation is to initiate positive pressure ventilation for respiratory support. Positive pressure ventilation, such as non-invasive positive pressure ventilation (NIPPV) or invasive mechanical ventilation, can help improve oxygenation and decrease the work of breathing for the patient. By providing adequate respiratory support, ventilation can reduce the negative effects of pulmonary edema and respiratory distress due to CHF exacerbation. Administering intravenous loop diuretics (Choice A) might be necessary to address fluid overload, but it is not the initial priority as ensuring adequate ventilation is crucial. Emergent pericardiocentesis (Choice C) is not indicated in this scenario as there is no mention of cardiac tamponade. Inotropic medications (Choice D) may be considered in managing acute exacerbation of CHF but
A patient presents with foul-smelling diarrhea containing cysts upon microscopic examination. Which of the following parasites is most likely responsible for this infection?
- A. Giardia lamblia
- B. Entamoeba histolytica
- C. Cryptosporidium parvum
- D. Cyclospora cayetanensis
Correct Answer: B
Rationale: Entamoeba histolytica is a parasitic protist known to cause amoebiasis, a gastrointestinal infection that can lead to symptoms such as foul-smelling diarrhea containing cysts. Upon microscopic examination of the feces, the presence of Entamoeba histolytica cysts is a key diagnostic feature. This parasite can be transmitted through contaminated food or water, and individuals infected with Entamoeba histolytica may experience abdominal pain, bloody diarrhea, and weight loss. Proper diagnosis and treatment are essential to manage this infection and prevent complications.
Which of the following herbal medicines is recommended by the department for cough?
- A. Sambong
- B. Bawang
- C. Guava
- D. Lagundi
Correct Answer: D
Rationale: The herbal medicine recommended by the Department of Health for cough is Lagundi (scientific name: Vitex negundo). Lagundi has been found to have properties that can help relieve cough, asthma, and other respiratory conditions. It has been traditionally used as a natural remedy for these purposes and has gained recognition for its effectiveness in managing cough symptoms. Additionally, Lagundi is also known for its anti-inflammatory and analgesic properties, further supporting its use in addressing respiratory ailments.
A patient presents with generalized weakness, headache, and difficulty concentrating. Laboratory tests reveal normocytic normochromic anemia, normal iron studies, and elevated serum erythropoietin levels. Which of the following conditions is most likely to cause these findings?
- A. Chronic kidney disease (CKD)
- B. Iron deficiency anemia
- C. Thalassemia
- D. Aplastic anemia
Correct Answer: A
Rationale: The patient in this scenario presents with normocytic normochromic anemia, normal iron studies, and elevated serum erythropoietin levels. These findings are characteristic of anemia of chronic disease, which is commonly seen in patients with chronic kidney disease (CKD). In CKD, there is a decrease in renal production of erythropoietin, leading to reduced stimulation of erythropoiesis and subsequent anemia. The normocytic normochromic anemia pattern is typical in anemia of chronic disease, as opposed to microcytic hypochromic anemia seen in iron deficiency anemia and thalassemia. Aplastic anemia is characterized by pancytopenia, which is not described in the scenario. Therefore, the most likely cause of the patient's presentation is chronic kidney disease.
