Adult Health Nursing First Chapter Quizlet

Correct Answer: B

Rationale: Cohort studies are types of epidemiological studies that involve a group of individuals who share a common characteristic or experience and are followed over time to observe the development of a particular health outcome. This type of study is useful in determining the incidence of a disease, identifying risk factors, and studying the natural history of a disease. Cohort studies allow researchers to investigate the relationship between exposure and outcome by following participants forward in time. It helps in establishing causality and is particularly useful for studying rare exposures or outcomes. In contrast, cross-sectional studies involve collecting data from a population at a single point in time, experimental studies involve interventions and control groups, and case-control studies involve comparing individuals with a particular health outcome (cases) to those without the outcome (controls) retrospectively.

Correct Answer: C

Rationale: The described presentation of a yellowish-white spot on the cornea with a ring of inflammation, along with branching, filamentous opacities extending from the corneal lesion, is characteristic of fungal keratitis. Fungal keratitis typically presents with these specific features on clinical examination.

Correct Answer: B

Rationale: Digitalis therapy, commonly prescribed for heart conditions, is known for its narrow therapeutic range and potential for toxicity. In the case of Patient Lily, who has been on digitalis therapy since she was pregnant, the nurse would anticipate the continuation of the same dosage to maintain the therapeutic effects and reduce the risks of toxicity. It is essential to monitor the patient's digitalis levels regularly and adjust the dosage if necessary based on the patient's response and any changes in their clinical status. Switching to a more potent drug, changing the medication, or adding a diuretic would not be appropriate without further assessment and consultation with the healthcare provider managing Lily's digitalis therapy.

Correct Answer: A

Rationale: It is recommended for nurses to conduct physical assessments on school children at least three times a year, or thrice a year. This frequency allows nurses to monitor the children's growth and development, assess any changes in their health status, and provide early intervention if needed. Regular physical assessments help ensure that any health issues are identified promptly and addressed appropriately, promoting the overall well-being and academic performance of the students.

Correct Answer: A

Rationale: Following total hip arthroplasty (THA), patients are at an increased risk of developing deep vein thrombosis (DVT) due to factors such as immobility, surgery-related vascular damage, and hypercoagulability. DVT refers to the formation of blood clots in the deep veins, typically in the lower extremities. These clots can break loose and travel to the lungs, causing a potentially life-threatening condition called pulmonary embolism (PE). Therefore, monitoring for signs and symptoms of DVT is crucial in the immediate postoperative period to promptly detect and prevent the development of complications such as PE. Common signs of DVT include leg swelling, pain, warmth, and redness. Additionally, healthcare providers may employ preventive measures such as early ambulation, compression stockings, and anticoagulant therapy to reduce the risk of DVT post-THA surgery.
