A patient presents with gradual-onset weakness, spasticity, hyperreflexia, and positive Babinski sign. Imaging reveals demyelinating plaques in the white matter of the brain and spinal cord. Which of the following neurological conditions is most likely responsible for these symptoms?

Correct Answer: B

Rationale: The symptoms described - gradual-onset weakness, spasticity, hyperreflexia, positive Babinski sign, and demyelinating plaques in the white matter of the brain and spinal cord - are indicative of multiple sclerosis (MS). MS is an autoimmune disease where the body's immune system attacks the myelin sheath, leading to the formation of plaques in the central nervous system. The characteristic symptoms of MS include weakness, spasticity (stiffness in muscles), hyperreflexia (exaggerated reflex responses), and positive Babinski sign (upward movement of the big toe). While ALS (Amyotrophic lateral sclerosis) presents with progressive muscle weakness and atrophy without sensory involvement and demyelinating plaques, Guillain-Barré syndrome (GBS) is typically an acute inflammatory demyelinating polyneuropathy affecting peripheral nerves rather than the central nervous system, and myast

Correct Answer: B

Rationale: The Epidemiologic Triad model focuses on identifying the causative factors of diseases, particularly infectious diseases. The three components of the triad are the external agent, the susceptible host, and the environment. These factors interact to result in the occurrence of disease. Treatment Regimen, on the other hand, is not one of the causative factors but rather a response to manage and treat the disease once it has occurred. While treatment is essential, it is not part of the factors that contribute to the initial development of the disease within the Epidemiologic Triad model.

Correct Answer: D

Rationale: The correct approach for formulating statements of findings in a study is to extract meanings and themes from significant statements. This involves analyzing the data collected, identifying patterns or themes that emerge from the responses, and then formulating statements that encapsulate these findings. By doing so, the researcher can accurately capture the essence of the data and present meaningful conclusions based on the analysis. This process goes beyond merely summarizing or describing the responses and delves deeper into the interpretations and implications of the findings.

Correct Answer: C

Rationale: Ventricular tachycardia (VT) is a potentially life-threatening arrhythmia characterized by wide QRS complexes and absence of P waves on electrocardiogram (ECG). Patients with VT may present with symptoms such as chest pain, dyspnea, and syncope due to reduced cardiac output and ineffective pumping of the heart. VT is a serious condition that requires prompt treatment to prevent hemodynamic compromise and potential cardiac arrest. Stable angina typically presents with chest pain that is provoked by exertion and relieved by rest or nitroglycerin. Atrial fibrillation is characterized by an irregularly irregular rhythm with absent P waves on ECG. Supraventricular tachycardia typically presents with a narrow QRS complex on ECG.

Correct Answer: C

Rationale: Neuman's adaptation model, also known as the Neuman Systems Model, is a nursing theory that focuses on how individuals respond to stressors in their environment. The model views individuals as being in a constant state of dynamic equilibrium, where they are interacting with stressors that can disrupt their normal functioning. Nursing care, according to this model, is aimed at helping individuals maintain or restore their optimal level of wellness by assisting them in adapting to these stressors. Therefore, Nurse Sandy's selection of a framework that emphasizes the constant relationship between humans and stressors in the environment aligns best with Neuman's adaptation model.

Correct Answer: A

Rationale: The presentation described in the question is most consistent with anterior uveitis. Anterior uveitis, also known as iritis, is characterized by redness, pain, and photophobia in the affected eye. Slit-lamp examination typically reveals ciliary injection (reddening of the conjunctiva and episclera), corneal edema, and a mid-dilated pupil with a fixed reaction to light (miosis). This occurs due to inflammation within the anterior chamber of the eye involving the iris and ciliary body.

Correct Answer: D

Rationale: The bio-ethical principle of veracity pertains to honesty and truthfulness in healthcare communication. By providing fraudulent information about the patient's diagnosis and prognosis, the nurse would be violating the principle of veracity. It is crucial for healthcare providers to be honest and provide accurate information to patients in order to ensure informed decision-making and uphold the trust between healthcare professionals and their patients. Misleading a patient about their diagnosis and prognosis can have serious consequences on the patient's understanding of their condition, treatment decisions, and overall well-being. Therefore, maintaining honesty and truthfulness is essential in promoting ethical healthcare practices.

Correct Answer: B

Rationale: The nurse's priority action after noticing a sudden drop in blood pressure after administering anesthesia is to assess the patient's airway, breathing, and circulation (ABCs). This is crucial to determine the immediate cause of the sudden drop in blood pressure and to ensure the patient's safety and stability. Assessment of the ABCs will help identify any potential airway obstruction, respiratory distress, or circulatory issues that may be contributing to the drop in blood pressure. Once the assessment is done, appropriate interventions can be initiated to stabilize the patient's condition. Administering vasopressors, documenting the blood pressure readings, and notifying the anesthesiologist are important actions but assessing the ABCs takes precedence in this situation to ensure the patient's immediate needs are addressed.

Correct Answer: A

Rationale: A nursing assistant can be delegated the task of changing wound dressings because it is considered a basic nursing care activity that does not require specialized training or knowledge. Nursing assistants are trained to perform tasks related to personal care, hygiene, and basic wound care under the supervision of a registered nurse. Changing wound dressings is a routine nursing task that can be safely delegated to a nursing assistant, allowing the nurse to focus on other aspects of patient care that require specialized nursing skills and knowledge.
