Correct Answer: D

Rationale: In the scenario described, the patient is experiencing severe hypoxemia refractory to conventional oxygen therapy, indicating a need for advanced respiratory support. When a patient with ARDS fails to respond to conservative management, including mechanical ventilation strategies, prone positioning, and recruitment maneuvers, the next step may involve extracorporeal membrane oxygenation (ECMO). ECMO provides a way to bypass the lungs and oxygenate the blood directly, allowing for enhanced gas exchange and support for severely compromised respiratory function. Therefore, in this critical situation, prioritizing the recommendation for ECMO can offer the patient the best chance of improving oxygenation and survival.

Correct Answer: A

Rationale: The patient's symptoms of fever, chills, headache, and myalgia after returning from sub-Saharan Africa are consistent with malaria. Intraerythrocytic ring forms and trophozoites observed on blood smear examination are characteristic of Plasmodium species, particularly Plasmodium falciparum, which is the most common and deadliest species causing malaria in sub-Saharan Africa. Plasmodium falciparum can lead to severe complications, such as cerebral malaria, if not promptly treated. Trypanosoma cruzi causes Chagas disease, not malaria. Borrelia burgdorferi is responsible for Lyme disease, which typically presents with a different set of symptoms like erythema migrans rash. Leishmania donovani causes visceral leishmaniasis, not malaria.

Correct Answer: B

Rationale: The medication given after a successful vaginal delivery that helps to hasten uterine contractility and control bleeding is typically an oxytocic agent, such as oxytocin. Oxytocin helps the uterus to contract effectively, which is important for preventing excessive bleeding after delivery. This medication is commonly used in the postpartum period to help the uterus return to its normal size and position. The supervisor reassured the newly hired nurse that everything will be fine because this medication will help promote uterine contractions and control bleeding, which are crucial steps in the postpartum management.

Correct Answer: A

Rationale: Research at work is an example of self-directed learning activity because it involves taking the initiative to seek out information, learn new skills, and solve problems independently within a workplace setting. This type of learning requires self-motivation, self-discipline, and autonomy to set goals, gather resources, and develop knowledge or expertise in a specific area. Individuals engage in research at work to enhance their professional growth, expand their skill set, or address challenges encountered in their job responsibilities. It is a proactive approach to learning where individuals take charge of their own development and continuously strive to improve their performance.
