A patient presents with gradual-onset memory loss, confusion, and difficulty with complex tasks such as managing finances and planning. Over time, the patient develops disorientation to time and place and requires assistance with activities of daily living. Which of the following neurological conditions is most likely responsible for these symptoms?

Correct Answer: A

Rationale: The patient's presentation of gradual-onset memory loss, confusion, difficulty with complex tasks, disorientation, and functional decline are all classic features of Alzheimer's disease. Alzheimer's disease is a progressive neurodegenerative disorder characterized by the accumulation of abnormal protein deposits in the brain, leading to widespread neuronal damage and cognitive decline. As the disease progresses, patients typically experience worsening memory loss, cognitive impairment, and deficits in activities of daily living, ultimately requiring full-time care and assistance. Other neurodegenerative diseases such as Parkinson's disease, Huntington's disease, and frontotemporal dementia may present with cognitive impairment and behavioral changes, but the specific constellation of symptoms described in the case is most indicative of Alzheimer's disease.

Correct Answer: B

Rationale: The correct action for the nurse to ensure patient safety during a bedside bronchoscopy procedure is to obtain informed consent from the patient or their legal representative. Informed consent is a vital ethical and legal requirement before any medical procedure. It ensures that the patient understands the risks, benefits, and alternatives of the procedure, as well as gives the patient the authority to make decisions about their healthcare. By obtaining informed consent, the nurse ensures that the patient has been properly informed and agrees to undergo the bronchoscopy, which promotes patient autonomy and safety. Administering sedation, using topical anesthesia, and restricting food intake are also important aspects of bronchoscopy preparation, but obtaining informed consent is the primary action to prioritize patient safety.

Correct Answer: C

Rationale: Deductive reasoning is a logical process in which conclusions are drawn from a set of premises or given information. In quantitative research, this type of reasoning is commonly used to test hypotheses and make predictions based on theories and existing knowledge. Researchers start with established theories or hypotheses and then collect data to either support or refute them. This structured approach aligns with the principles of deductive reasoning and is a key characteristic of quantitative research methodology.

Correct Answer: A

Rationale: In the case of a displaced fracture of the distal radius and ulna, the preferred initial treatment is typically closed reduction and splinting. Closed reduction involves manually realigning the fractured bones without the need for surgery. Splinting is then utilized to immobilize the wrist and forearm to allow for proper healing of the fracture. This approach is often effective in realigning the bones and stabilizing the injury, allowing for adequate healing without the need for more invasive interventions like surgery. Following the initial management with closed reduction and splinting, the patient's progress will be monitored, and further interventions may be considered based on the specific characteristics of the fracture and the patient's response to treatment.

Correct Answer: B

Rationale: Warming up ofloxacin eardrops before administering is done to prevent dizziness, which can occur if a cold solution is placed in the ear. Holding the bottle with hands for about 1 to 2 minutes is usually sufficient to warm up the solution to a comfortable temperature for the patient. Warming the solution for too long, such as 5-6 minutes, may not be necessary and could potentially waste time. So, the correct duration for warming up ofloxacin eardrops is 1 to 2 minutes.

Correct Answer: D

Rationale: The most likely cause of the sudden onset of severe abdominal pain and dark red vaginal bleeding with a tender, firm uterus at 28 weeks gestation is abruptio placentae. Abruptio placentae, also known as placental abruption, is the premature separation of the placenta from the uterine wall before delivery. This condition can be life-threatening to both the mother and the fetus, as it can lead to severe bleeding and compromise the oxygen and nutrients supply to the fetus. The presentation typically includes severe abdominal pain, dark red or maroon vaginal bleeding, uterine tenderness, and a firm uterus due to the blood accumulation behind the placenta. Prompt recognition and intervention are crucial to prevent adverse maternal and fetal outcomes.

Correct Answer: B

Rationale: In a patient with acute respiratory failure and hypercapnia due to a COPD exacerbation, the most appropriate intervention is the initiation of non-invasive positive pressure ventilation (NIPPV). NIPPV helps improve ventilation and oxygenation by providing mechanical support to the patient's breathing without the need for endotracheal intubation. It can reduce the work of breathing, decrease carbon dioxide retention, and improve respiratory muscle function. This intervention is particularly beneficial for COPD exacerbations as it can help alleviate hypercapnia and hypoxemia, leading to improved outcomes and potentially reducing the need for invasive ventilation methods. Therefore, NIPPV is the recommended management strategy in this scenario.

Correct Answer: B

Rationale: Option B, "Maintaining professional boundaries helps protect both patients and nurses," indicates an understanding of the importance of professional boundaries in nursing practice. Professional boundaries define the limits of the nurse-patient relationship and help ensure that interactions are safe, therapeutic, and based on the patient's best interest. By maintaining these boundaries, nurses can uphold ethical standards, prevent harm, and maintain trust with patients. It also helps prevent issues such as transference, countertransference, and breaches of confidentiality. Overall, understanding and respecting professional boundaries are essential for promoting the well-being of both patients and healthcare providers.

Correct Answer: A

Rationale: The inappropriate use of restraints or seclusion is considered a form of false imprisonment, which is an intentional tort. False imprisonment occurs when someone intentionally restricts another person's freedom of movement without their consent or legal justification. In healthcare settings, using restraints or seclusion inappropriately on a patient can constitute false imprisonment if it is not done for the safety of the patient or others and without proper authorization. This act can lead to legal consequences and liabilities for healthcare providers.
