A patient presents with fever, chills, headache, and myalgia after returning from a trip to sub-Saharan Africa. Laboratory tests reveal intraerythrocytic ring forms and trophozoites on blood smear examination. Which of the following is the most likely causative agent?
- A. Plasmodium falciparum
- B. Trypanosoma cruzi
- C. Borrelia burgdorferi
- D. Leishmania donovani
Correct Answer: A
Rationale: The most likely causative agent in this scenario is Plasmodium falciparum, a protozoan parasite that causes malaria. The patient's symptoms of fever, chills, headache, and myalgia align with the typical presentation of malaria. Additionally, the presence of intraerythrocytic ring forms and trophozoites on blood smear examination is characteristic of Plasmodium species, particularly P. falciparum, which causes the most severe form of malaria.

Patients like Emmy who have experienced delayed hypersensivity to latex FREQUENTLY complains of ______.
- A. flushing, bronchospasm
- B. urticaria, laryngeal edema
- C. rhinitis, conjunctivitis, blisters
- D. papules, vesicles, pruritus
Correct Answer: C
Rationale: Patients like Emmy who have experienced delayed hypersensitivity to latex typically present with symptoms such as rhinitis (runny or stuffy nose) and conjunctivitis (inflammation of the eyes). In addition, delayed hypersensitivity reactions often involve skin manifestations, such as blisters. These symptoms are reflective of the inflammatory response triggered by exposure to latex in individuals with delayed hypersensitivity. Symptoms like flushing, bronchospasm, urticaria, laryngeal edema, papules, vesicles, and pruritus are more commonly associated with immediate-type hypersensitivity reactions rather than delayed hypersensitivity reactions in latex-sensitive individuals.
When a patient is diagnosed to have pneumonia, the breath sounds detected by the nurse on auscultation of the affected area would be ______.
- A. wheezing sounds
- B. fine crackles
- C. stridor
- D. deep and low-pitched breath sounds
Correct Answer: B
Rationale: When a patient is diagnosed with pneumonia, the breath sounds detected by the nurse on auscultation of the affected area would typically include fine crackles. Fine crackles are discontinuous, high-pitched crackling or rattling sounds heard during inspiration that indicate the presence of fluid in the small airways or alveoli. These crackles are caused by the movement of secretions or exudate within the bronchioles or alveoli, which is a common characteristic of pneumonia. Wheezing sounds are usually associated with conditions such as asthma, bronchitis, or COPD and are caused by narrowed airways. Stridor is a high-pitched, crowing sound that typically indicates an obstruction in the upper airway and is often heard in cases of laryngeal inflammation or foreign body aspiration. Deep and low-pitched breath sounds are more characteristic of conditions like chronic bronchitis.
A patient presents with crushing chest pain that lasts longer than 20 minutes, diaphoresis, and dyspnea. An electrocardiogram (ECG) shows ST-segment elevation in the anterior leads. Which cardiovascular disorder is most likely responsible for these symptoms?
- A. Stable angina
- B. Unstable angina
- C. Acute myocardial infarction
- D. Prinzmetal's angina
Correct Answer: C
Rationale: The patient is most likely experiencing an acute myocardial infarction (MI) based on the presentation of crushing chest pain lasting longer than 20 minutes, diaphoresis, dyspnea, and ST-segment elevation on the ECG. These symptoms are consistent with the classic presentation of an ST-segment elevation myocardial infarction (STEMI), which is a type of acute MI that is characterized by prolonged ischemia leading to myocardial cell death. In this case, the ST-segment elevation in the anterior leads indicates myocardial damage in the corresponding area of the heart supplied by the affected coronary artery. This is a medical emergency that requires urgent intervention to restore blood flow to the affected myocardium and prevent further complications.
Mang Emilio refuses to take his daily medication for hypertension. Which of the following actions should Nurse Pedrito take at this time?
- A. Tell MangEmilio that he will suffer from stroke.
- B. Explore the reason for the client's refusal to take the medication.
- C. Administer the medication by injection.
- D. Obtain help from relatives in administering the medication.
Correct Answer: B
Rationale: The most appropriate action for Nurse Pedrito to take at this time is to explore the reason for Mang Emilio's refusal to take his daily medication for hypertension. By understanding the underlying cause of his refusal, Nurse Pedrito can address any concerns or barriers that may be preventing Mang Emilio from adhering to his medication regimen. This approach emphasizes the importance of patient-centered care and communication in promoting medication compliance and overall health outcomes. Additionally, it allows Nurse Pedrito to work collaboratively with Mang Emilio to find a solution that meets his needs and preferences.
Ella's feeling of joining lory in heaven is a manifestation of:
- A. Suicidal intent
- B. Paranoia
- C. Suicidal threat
- D. Suicidal ideation

In this scenario, Ella is not explicitly expressing any immediate intent to harm herself or others, nor is she exhibiting paranoia or making a direct threat. Instead, her mention of joining Lory in heaven suggests that she is contemplating the idea of death, which falls under the category of suicidal ideation. It is essential to take such thoughts seriously and seek appropriate help and support for the individual experiencing them.
