Correct answer:

The correct answer is B because it is important for a nursing assistant to explain the procedure to be performed to ensure informed consent and promote resident autonomy. By explaining the procedure, the resident can understand what will happen and feel more comfortable and involved in their care. This fosters a trusting and respectful relationship between the nursing assistant and the resident. Choice A is incorrect because it assumes the resident knows who the nursing assistant is, which may not always be the case. Choice C is incorrect because reassuring the resident that she will not have to do anything during the procedure may not be necessary for all procedures and may not address the resident's specific concerns. Choice D is incorrect because withholding information from the resident can lead to mistrust and anxiety.

Correct answer:

Post-cardiac arrest with return of spontaneous circulation (ROSC) benefits from therapeutic hypothermia (32-36°C) to limit brain injury. Cooling lowers the cerebral metabolic rate, reducing oxygen and glucose demand, which curbs secondary damage from reperfusion. It also decreases intracranial pressure by minimizing edema and inflammation, preserving neurological function critical after hypoxia. Reducing stored energy use is a minor effect, not the primary goal. Redirecting blood flow isn't the mechanism; hypothermia globally slows metabolism. Cardiac output doesn't increase contractility may even decrease slightly but neuroprotection outweighs this. Per AHA guidelines, this intervention improves outcomes in comatose ROSC patients, targeting brain preservation over systemic effects, making it a cornerstone of post-arrest care.

Correct answer:

The correct answer is A because type 1 diabetes mellitus is a well-known risk factor for erectile dysfunction due to its impact on blood flow and nerve function. Diabetes can damage blood vessels and nerves that are essential for achieving and maintaining an erection. This patient's long history of type 1 diabetes increases the likelihood of developing erectile dysfunction. Choices B, C, and D are incorrect because urinary tract infections, blood pressure medications, and an enlarged prostate gland are not directly associated with erectile dysfunction. Urinary tract infections typically do not affect erectile function, blood pressure medications may have erectile dysfunction as a side effect but are not a direct risk factor, and an enlarged prostate gland is more related to urinary symptoms rather than erectile dysfunction.

Correct answer:

The correct answer is B because only advanced practice nurses, such as psychiatric nurse practitioners, have the authority to prescribe psychotropic medications. This action falls under their scope of practice and requires advanced education and training in pharmacology and mental health. Asking an advanced practice nurse to prescribe psychotropic medication ensures that patients receive appropriate and safe pharmacological interventions. A: Mental health assessment interviews can be performed by staff nurses, not limited to advanced practice nurses. C: Establishing therapeutic relationships is a fundamental nursing skill that all nurses, including staff nurses, should possess. D: Individualizing nursing care plans is a responsibility of all nurses and does not specifically require involvement of advanced practice nurses.

Correct answer:

The correct answer is C: Sitting while performing tasks like cooking or ironing. This strategy helps conserve energy by reducing the strain on the respiratory system, which is important for clients with chronic bronchitis. Sitting minimizes the energy expenditure required for these tasks, allowing the client to conserve energy for other activities. Choice A is incorrect because avoiding long periods of rest is not recommended for clients with chronic bronchitis as they need to conserve energy to prevent exacerbations. Choice B is incorrect because high-intensity exercises can actually worsen symptoms and strain the lungs in clients with chronic bronchitis. Choice D is incorrect because taking deep breaths before physical activity may not necessarily conserve energy and could potentially lead to increased respiratory effort.

Correct answer:

The correct answer is D: "Ensuring adequate oxygenation and ventilation" should be performed first in any patient with potential multiple closed extremity fractures. This is because prioritizing oxygenation and ventilation is crucial to prevent hypoxia and respiratory compromise, which can be life-threatening. Once the patient's oxygenation and ventilation are stabilized, further assessments and interventions can be performed. A: "A thorough assessment of four limb perfusion" may be important but ensuring adequate oxygenation and ventilation takes precedence. B: "Maneuvers to prevent necrosis of the skin" is not the immediate priority over ensuring oxygenation and ventilation. C: "Extremity compartment syndrome release" is a critical intervention but should be performed after ensuring adequate oxygenation and ventilation.

Correct answer:

The correct answer is A: Seborrheic keratosis. This diagnosis is likely due to the lesion's raised, rough, and wart-like appearance, which is characteristic of seborrheic keratosis. Seborrheic keratosis is a common benign skin growth that typically appears in older individuals and presents as brown, black, or tan growths with a waxy, stuck-on appearance. It is important to note that seborrheic keratosis is non-cancerous and does not require immediate medical treatment. Summary: - B: Basal cell carcinoma typically presents as a pearly or waxy bump, not a raised, rough lesion with a wart-like appearance. - C: Actinic keratosis is a precancerous skin condition characterized by rough, scaly patches, not a raised, wart-like lesion. - D: Squamous cell carcinoma usually appears as a firm red nodule or a flat lesion with a scaly

Correct answer:

Hand hygiene is considered the most effective method to prevent the spread of infection in a healthcare setting. Proper hand hygiene, including washing hands with soap and water or using hand sanitizer, is crucial in reducing the transmission of pathogens from one person to another. While wearing personal protective equipment, sterilizing equipment, and isolating infected patients are also important infection control measures, they are not as universally effective as hand hygiene in preventing the spread of infections. Personal protective equipment can prevent contact with infectious materials, sterilizing equipment reduces the risk of contamination, and isolating infected patients helps prevent the spread of specific infections, but they are more targeted approaches compared to the broad and essential practice of hand hygiene.

Correct answer:

The most critical action for the nurse to take when a client with diabetes mellitus presents with symptoms of hyperglycemia such as polyuria, polydipsia, and polyphagia is to monitor the client's blood glucose level. This action helps in assessing the client's current glycemic status and guides further interventions. Encouraging increased fluid intake (Choice B) may be beneficial in managing dehydration caused by polyuria, but it does not address the underlying cause of hyperglycemia. Administering insulin as prescribed (Choice C) may be necessary based on the blood glucose monitoring results, but monitoring should precede any medication administration. Assessing the client's urine output (Choice D) is important but does not directly address the primary concern of evaluating and managing hyperglycemia in a client with diabetes.

Correct answer:

The correct answer is C because the Affordable Care Act (ACA) expands the role of pharmacists in disease management and medication therapy management. This is achieved through provisions that promote team-based care, medication therapy management services, and collaborative practice agreements. Pharmacists are now able to provide more comprehensive care, leading to improved patient outcomes. Choice A is incorrect because the ACA aims to improve patient access to healthcare, not specifically medication therapies. Choice B is incorrect as the ACA focuses on increasing access to care rather than increasing prescription drug regulations or affecting pharmacy reimbursements. Choice D is incorrect as the ACA aims to improve access to medications and healthcare services, not reduce access or impose stricter medication regulations.
