A patient with chronic obstructive pulmonary disease (COPD) is admitted to the hospital with acute exacerbation and respiratory failure requiring mechanical ventilation. Which of the following ventilator settings is most appropriate for minimizing the risk of ventilator-induced lung injury (VILI) in this patient?

Correct Answer: A

Rationale: Patients with COPD are at increased risk for developing ventilator-induced lung injury (VILI) due to their underlying lung pathology. Using a low tidal volume strategy (6-8 ml/kg predicted body weight) has been shown to reduce the risk of VILI in these patients. Additionally, applying high positive end-expiratory pressure (PEEP) helps to recruit collapsed alveoli, improve oxygenation, and decrease the risk of barotrauma by keeping the alveoli open throughout the respiratory cycle. Therefore, the most appropriate ventilator settings to minimize the risk of VILI in a COPD patient with acute exacerbation and respiratory failure requiring mechanical ventilation would be low tidal volume and high PEEP.

Correct Answer: A

Rationale: The patient's presentation of a pruritic, annular rash with fine scaling and central clearing, affecting the trunk and proximal extremities, following exposure to a new soap and laundry detergent is most consistent with tinea corporis, commonly known as ringworm. Ringworm is a superficial fungal infection caused by dermatophytes that can present with circular or annular lesions with central clearing and scaling. The exposure to new soap and laundry detergent may have disrupted the skin's microbiome, making it more vulnerable to fungal infections like tinea corporis. Nummular eczema typically presents as coin-shaped plaques rather than annular lesions, while pityriasis rosea presents with a herald patch followed by smaller similar lesions in a "Christmas tree" distribution. Lichen planus would not typically be associated with exposure to new soap and laundry detergent but can have distinct purple, polygonal papules.

Correct Answer: A

Rationale: The best response is to ask Ms. C why she is running and trotting around the room. This approach is empathetic and allows for open communication to understand her behavior. It is important to gather information before jumping to conclusions or making threats about changing her exercise program or eating habits. By showing concern and curiosity, you can address the situation in a supportive and constructive manner.

Correct Answer: C

Rationale: The described presentation of a yellowish-white spot on the cornea with branching, filamentous opacities is characteristic of fungal keratitis. Fungal keratitis is typically associated with agricultural injuries, trauma involving plant material, or contact lens wear in agricultural environments. Fungal keratitis can be serious and may require intensive antifungal treatment to prevent vision loss. Prompt diagnosis and initiation of appropriate antifungal therapy are essential in managing fungal keratitis.

Correct Answer: C

Rationale: In qualitative research, a focus group discussion is a technique where a group of participants are brought together to discuss specific topics in depth. In this case, Nurse Carmi's plan to gather 6 participants who are victims of domestic violence aligns well with the focus group discussion technique. By involving multiple participants who have experienced domestic violence, she can facilitate a dynamic conversation to gather rich data and insights. This approach allows for the exploration of diverse perspectives, experiences, and opinions within the group setting, providing a deeper understanding of the issue at hand. Additionally, focus group discussions can be more cost-effective and efficient than conducting individual interviews when working with a small group of participants. Therefore, conducting a focus group discussion would be an appropriate qualitative research technique for Nurse Carmi's plan to gather data from victims of domestic violence for her questionnaires.

Correct Answer: A

Rationale: The Professional Regulation Commission (PRC) in the Philippines requires nurses like Nurse Merle to comply with 45 units of Continuing Professional Development (CPD) in order to renew their license and continually practice nursing. This is a mandatory requirement to ensure that nurses stay updated with the latest advancements, skills, and knowledge in the field of nursing. By completing the required CPD units, Nurse Merle can enhance her competency, maintain her license, and provide quality care to her patients.

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.

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: D

Rationale: A correlational research design is most appropriate when the aim is to find a relationship between two variables. Correlational studies examine how variables are related to each other without manipulating them. This design allows researchers to determine the strength and direction of the relationship between variables, providing valuable insights into the potential associations between different factors. Phenomenological studies focus on understanding individuals' experiences, exploratory studies investigate a topic without predefined hypotheses, and experimental studies involve manipulating variables to observe their effects. Therefore, in the context of aiming to find a relationship between two variables, a correlational research design is the most suitable choice.
