Question 1 of 5
The researcher must critically appraise evidence following a literature review. Which questions should the researcher pose in this appraisal?
Correct Answer: C
Rationale: 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.
Question 2 of 5
A client has a Staphylococcus infection in a decubitus ulcer. In this case, Staphylococcus is the:
Correct Answer: B
Rationale: In the Agent-Host-Environment Model, Staphylococcus is the agent the causative factor triggering illness, here infecting a decubitus ulcer. The client is the host, whose skin integrity and immunity determine susceptibility. The environment bedridden conditions or hygiene sets the stage for infection. The disease is the resulting pathology, like the ulcer's worsening. This model dissects causation: Staphylococcus (bacteria) invades the host (client) in a conducive environment (immobility), driving nursing interventions cleaning wounds, repositioning to disrupt the triad. Understanding the agent's role guides targeted care, like antibiotics, breaking the infection cycle. It's a practical lens for nurses, pinpointing external triggers to prevent or manage illness effectively, especially in chronic wound scenarios.
Question 3 of 5
A nurse provides care to clients of a community clinic that serves a large immigrant population. Which intervention reflects primary prevention for this group?
Correct Answer: B
Rationale: Primary prevention stops illness before it starts, vital for immigrants facing unique risks. Providing vaccinations like measles or flu shots builds immunity, preventing outbreaks in a group often under-vaccinated due to access or prior country norms, a top nursing action in clinics. Screening for tuberculosis is secondary, catching disease early, common in immigrant health but not preventive. Referring hypertension cases or teaching diabetic foot care is tertiary, managing existing conditions, not averting onset. Vaccinations align with primary prevention's proactive stance data shows they cut infectious disease rates in such populations addressing environmental and social vulnerabilities. Nursing leverages this to protect community health, ensuring immigrants, often in crowded settings, dodge preventable illnesses, a practical, impactful step for this clinic's focus.
Question 4 of 5
The parents of a healthy 6-year-old ask the nurse for advice about preventing obesity in their child. Which response reflects health promotion?
Correct Answer: A
Rationale: For a healthy 6-year-old, health promotion prevents obesity by fostering active habits limiting screen time and encouraging outdoor play boosts physical activity, burning calories and building muscle, key to avoiding weight gain at this age. Evidence links sedentary screen hours to childhood obesity; play counters it, aligning with nursing's focus on lifestyle over surveillance. Monthly weighing is secondary, tracking not preventing, and may stress the child. Multivitamins don't prevent obesity caloric balance does while annual cholesterol checks detect, not avert, issues. The nurse's reply promotes wellness through fun, practical steps like biking or tag tailored to a child's energy, ensuring long-term health without medicalizing a well kid, a cornerstone of pediatric nursing's preventive approach.
Question 5 of 5
The nurse notes small, pimple-like pustules all over the newborn's body. When charting the integumentary assessment of this newborn, which normal finding does the nurse note?
Correct Answer: C
Rationale: Small, pimple-like pustules on a newborn's body suggest erythema toxicum (C), a benign, self-limiting rash common in the first week of life, often with erythematous macules and pustules. Strawberry hemangiomas (A) are vascular growths, not pustular. Port-wine stains (B) are flat, purple birthmarks. Telangiectatic nevi simplex (D) are salmon-colored patches, not pustules. C is correct. Rationale: Erythema toxicum affects up to 70% of newborns, caused by an immune response, resolving without treatment, distinct from vascular or permanent lesions, aligning with normal neonatal skin findings.
