The first standard-step-in oxygen therapy that the nurse should do is which of the following?

Correct Answer: D

Rationale: Before initiating any oxygen therapy, it is crucial for the nurse to first assess the patient's condition. This step allows the nurse to determine the patient's oxygen saturation levels, respiratory rate, lung sounds, and overall respiratory status. Understanding the patient's baseline condition helps in selecting the appropriate oxygen delivery method and flow rate that will best meet the patient's needs. Additionally, assessing the patient's condition allows the nurse to monitor the effectiveness of the oxygen therapy and make any necessary adjustments throughout the treatment process. Therefore, assessing the patient's condition is the necessary first step in providing safe and effective oxygen therapy.

Correct Answer: C

Rationale: Nurse Ace submitting a report to the physician about committing an error in medication demonstrates accountability. Accountability in healthcare refers to the responsibility of individuals to answer for their actions, decisions, and behaviors in the professional setting. By taking ownership of the mistake and informing the physician, Nurse Ace is showing accountability for her actions, ensuring that patient safety remains a priority. Compliance with reporting errors is essential for quality improvement and patient safety in healthcare settings.

Correct Answer: A

Rationale: Assessing the infant's latch and feeding effectiveness should be prioritized as the initial nursing intervention to address the client's concerns about inadequate milk supply. Poor latch can lead to ineffective milk removal, which may result in decreased milk production. By ensuring the infant is latching correctly and effectively transferring milk, the client's milk supply can be optimized. Education about techniques to increase milk production can be provided following the assessment of feeding effectiveness. Referring to a lactation consultant may be necessary for further evaluation and support if issues persist despite correcting the latch. Supplemental formula feedings should be recommended as a last resort after all other interventions have been attempted and if there are concerns about inadequate nutrition for the infant.

Correct Answer: B

Rationale: The presentation of a pruritic rash with linear streaks and small, fluid-filled blisters following exposure to poison ivy is characteristic of allergic contact dermatitis. Poison ivy contains an oil called urushiol, which is known to cause this type of skin reaction in individuals who are sensitive to it. The linear streaks are often a result of the plant brushing against the skin. Pemphigus vulgaris is an autoimmune condition characterized by the formation of intraepidermal blisters, typically not associated with linear streaks or exposure to irritants like poison ivy. Bullous pemphigoid is characterized by subepidermal blisters, and herpes zoster presents with a painful rash following reactivation of the varicella-zoster virus in a dermatomal pattern, not typically in linear streaks.

Correct Answer: C

Rationale: Dendritic cells play a critical role in initiating adaptive immune responses by capturing antigens from pathogens, migrating to lymphoid organs, and presenting these antigens to naïve T cells. This activation of naïve T cells by dendritic cells is essential for the adaptive immune system to generate specific immune responses against pathogens. Dendritic cells act as professional antigen-presenting cells, which are specialized to capture, process, and present antigens to T cells, thereby facilitating the activation of T cells and the coordination of adaptive immune responses, such as the production of specific antibodies and the generation of memory T cells.

Correct Answer: C

Rationale: Bronchoscopy is a procedure that allows direct visualization of the inside of the airways in the lungs. It is considered the most definitive method to establish a diagnosis of lung cancer as it can directly visualize any abnormal growths or tumors in the bronchial tubes. During bronchoscopy, tissue samples can be collected for biopsy to confirm the presence of cancer cells. This procedure is more accurate compared to other diagnostic methods such as chest x-ray, CT scan, cytological study of sputum, or magnetic resonance imaging in confirming a diagnosis of lung cancer.

Correct Answer: A

Rationale: Nurse Cris should employ the communication technique of summarizing to successfully capture the details of the meeting. Summarizing involves condensing the information provided into a concise and organized form, which would help Nurse Cris remember and retain the key points discussed during the meeting. By summarizing the details, Nurse Cris can ensure that no important information is missed and can also confirm understanding by reflecting back the main points discussed. This technique promotes effective communication by enhancing clarity and reinforcing comprehension.

Correct Answer: A

Rationale: Clients who are taught skills such as measuring blood glucose, taking blood pressure, changing dressings, and bathing infants are learning skills that involve physical movement and coordination. These activities require the integration of mental and physical skills, and they fall under the psychomotor domain of learning. In this domain, individuals develop physical skills and coordination through practice and repetition. The psychomotor domain is one of the three domains of learning, along with the cognitive domain (which involves knowledge and intellectual skills) and the affective domain (which involves emotions, values, and attitudes).

Correct Answer: B

Rationale: When a patient with chronic kidney disease is prescribed erythropoietin-stimulating agents (ESAs) for anemia management, the parameter that should be monitored closely by the nurse is the hemoglobin levels. Hemoglobin levels indicate the patient's response to ESA therapy and are essential in assessing the effectiveness of the treatment in addressing anemia. Monitoring hemoglobin levels helps ensure that the patient's anemia is controlled within the target range to avoid both the risks of under-treatment (resulting in persistent anemia) and over-treatment (increased risk of adverse outcomes such as hypertension, stroke, or cardiovascular events).
