Correct answer:

Preventing asthma exacerbations in adolescents hinges on educating them to recognize and avoid triggers e.g., allergens (pollen, pets), irritants (smoke), or exercise reducing inflammation and bronchospasm risk. This proactive strategy, central to asthma action plans (e.g., GINA), empowers teens to modify environments (e.g., using air filters) and preempt attacks, cutting hospital visits by up to 50%. Corticosteroids aren't rescue drugs albuterol is; inhaled steroids are maintenance, not acute. Alternative therapies (e.g., acupuncture) lack robust evidence for asthma control, secondary to standard care. Immunizations prevent infections like flu, which may trigger asthma, but aren't the primary prevention tool. The educator's focus on trigger education interactive, teen-friendly builds self-management skills, key for this age group's independence and long-term asthma control.

Correct answer:

The correct answer is D because it directly addresses the nursing diagnosis of ineffective coping related to feelings of loneliness and isolation. By identifying two alternative methods of coping, the patient can develop healthier strategies to manage these emotions instead of resorting to overeating and vomiting. This outcome promotes long-term behavioral change and helps the patient build resilience. Choice A is incorrect because expressing angry feelings may not necessarily address the underlying issues of loneliness and isolation. Choice B is incorrect as verbalizing positive things about oneself may be beneficial but does not directly address coping mechanisms for loneliness and isolation. Choice C is also incorrect because understanding the importance of a balanced diet does not directly address coping strategies for managing emotions like loneliness and isolation.

Correct answer:

Qualitative research in nursing explores narratives and experiences, not numbers, offering depth into human perspectives. Examining issues with Native American/First Nation clients uses ethnography, studying cultural health contexts. Investigating past trends is historical research, tracing nursing's evolution through stories. Discovering how illness affects lives is phenomenological, capturing lived experiences like cancer's emotional toll. Examining intervention effects or cause-and-effect in labs is quantitative, focusing on measurable outcomes, not narratives. Qualitative methods generate rich, contextual knowledge like understanding tribal healing views enhancing culturally sensitive care. This contrasts with quantitative's statistical focus, giving nurses tools to address subjective client needs, vital for holistic practice and advancing nursing's interpretive science.

Correct answer:

The correct answer is A: Use of accessory muscles during respiration. This finding in a patient with asthma indicates a need for immediate intervention because it signifies severe respiratory distress and impending respiratory failure. Accessory muscle use suggests that the patient is struggling to breathe and is unable to maintain adequate oxygenation. This requires prompt medical attention to prevent further deterioration. Summary: B: Oxygen saturation of 92% on room air may indicate mild hypoxemia but is not as urgent as the use of accessory muscles. C: Mild expiratory wheezing is a common finding in asthma exacerbations and may not necessarily require immediate intervention. D: Peak expiratory flow rate of 85% of personal best indicates moderate airflow limitation but does not necessarily require immediate intervention unless accompanied by other severe symptoms.

Correct answer:

The preoperative period begins when the patient is scheduled for surgery and ends when they are transferred to the surgical suite . It is a phase focused on preparation, including establishing the need for surgery and providing testing and education (not listed but implied). Choice A is incorrect because the preoperative period does not start with a surgeon's appointment, which is part of the decision-making process, not the formal preoperative phase. Choice B is true but incomplete alone, while choice C is accurate but not the sole descriptor. Choice D is the most precise starting point, as scheduling initiates the preoperative timeline, during which assessments, consents, and preparations occur. This period ensures the patient is physically and mentally ready for surgery, with safety protocols like lab tests and patient education occurring systematically after scheduling.

Correct answer:

A blood pressure reading of 120/80 mm Hg is considered normal according to widely accepted medical guidelines, such as those from the American Heart Association. The systolic pressure (120 mm Hg) represents the force when the heart contracts, and the diastolic pressure (80 mm Hg) reflects the pressure when the heart is at rest. Normal blood pressure is typically defined as systolic less than 120 mm Hg and diastolic less than 80 mm Hg, making Normal, correct. Prehypertension, applies to readings like 120-129/<80 mm Hg, but 120/80 exceeds this slightly yet remains within normal limits in many contexts. Hypotensive, indicates low blood pressure (e.g., below 90/60 mm Hg), which 120/80 clearly is not. Hypertensive, refers to high blood pressure (e.g., 130/80 mm Hg or higher), which this reading does not meet. Therefore, C is the accurate answer based on standard classifications.

Correct answer:

Step-by-step rationale for why Choice C is correct: 1. Transmission-Based Precautions are specific measures used in addition to Standard Precautions. 2. Standard Precautions are basic infection control practices to prevent the spread of infection. 3. Transmission-Based Precautions are used for patients with known or suspected infections that require additional precautions. 4. Therefore, Choice C is correct as Transmission-Based Precautions are practiced in addition to Standard Precautions. Summary: - Choice A is incorrect because Standard Precautions should always be followed regardless of Transmission-Based Precautions. - Choice B is incorrect as Transmission-Based Precautions are not the same as Standard Precautions. - Choice D is incorrect because proper communication and documentation are essential in healthcare, including listing precautions in the care plan.

Correct answer:

Critical appraisal in nursing research evaluates evidence quality and relevance post-literature review, ensuring findings guide practice effectively. Asking 'What were the results of each study?' identifies outcomes like reduced infection rates while 'Are the results valid and reliable?' assesses methodological rigor, checking biases or sample issues. 'Will the results improve client care?' gauges practical impact, linking evidence to real-world benefits. 'How many studies were found?' or 'Where were they conducted?' provide context but don't appraise quality. This process filters robust evidence like a study on hand hygiene reducing infections ensuring nurses apply trustworthy, applicable insights. It's a gatekeeper, preventing flawed data from skewing care, and aligns research with nursing's goal of enhancing patient outcomes through science, not just volume or geography.

Correct answer:

The correct answer is D because it provides the most direct and hands-on assistance to ensure completion of the shower. By walking her to the shower, assisting with undressing, starting the water, and providing necessary supplies and instructions, the patient is guided through each step of the showering process. This approach is essential for someone with significant apraxia and poor hygiene due to Alzheimer's disease. Choice A is incorrect because simply reminding the patient every 30 minutes may not address the physical assistance needed for shower completion. Choice B is also incorrect as discussing the importance of showers may not be enough to overcome the challenges of apraxia and poor hygiene. Choice C is not as effective as choice D as occasional reminders may not provide the comprehensive assistance required for the patient to successfully complete the shower.

Correct answer:

The nursing process is a systematic approach to client care, beginning with assessment (A), which involves collecting data about the client's health status. Taking vital signs after a client reports abdominal pain and diarrhea is a clear example of assessment, as it gathers objective physiological data (e.g., temperature, pulse, blood pressure) to evaluate the client's condition. Diagnosis (B) follows assessment and involves analyzing data to identify health problems, which has not yet occurred here. Planning (C) entails setting goals and interventions based on the diagnosis, while implementation (D) is the execution of those interventions neither of which apply to simply taking vital signs. This initial data collection is foundational to understanding the client's condition, guiding subsequent steps, and ensuring accurate care, making A the correct phase in this scenario.
