What part of the body regulates calcium and phosphate in the bloodstream?

Correct Answer: D

Rationale: The correct answer is D) Parathyroid glands. The parathyroid glands are responsible for regulating calcium and phosphate levels in the bloodstream through the secretion of parathyroid hormone (PTH). PTH helps to increase calcium levels in the blood by acting on the bones, kidneys, and intestines. Option A) Thyroid gland is incorrect because while the thyroid gland plays a crucial role in regulating metabolism through the secretion of hormones like T3 and T4, it is not directly involved in calcium and phosphate balance. Option B) The pancreas is incorrect because it is responsible for producing insulin and glucagon to regulate blood sugar levels, not calcium and phosphate. Option C) Adrenal glands are incorrect because they produce hormones like cortisol and adrenaline to regulate stress response and metabolism, but they do not directly regulate calcium and phosphate levels in the bloodstream. Understanding the role of the parathyroid glands in calcium and phosphate regulation is essential in the care of patients with conditions like Alzheimer's disease, as imbalances in these minerals can impact bone health, nerve function, and overall health. Nurses and healthcare providers need to have a solid foundation in the endocrine system to provide comprehensive care to patients with complex conditions.

Correct Answer: A

Rationale: In the context of caring for a patient with Alzheimer's who requires tube feeding, it is crucial to understand the possible complications that may arise. The correct answer, option A) Aspiration, is a significant concern with tube feeding. Aspiration can occur when food or liquid enters the airway instead of the esophagus, leading to serious respiratory issues such as pneumonia, especially in patients with cognitive impairments like Alzheimer's who may have difficulty swallowing or managing their secretions. Option B) Cystitis is unlikely to result from tube feeding, as cystitis is an inflammation of the bladder typically caused by infection. Option C) Loose lead and option D) Phlebitis are also unlikely complications of tube feeding, as they are more related to issues with IV therapy rather than enteral feeding. Educationally, understanding the potential complications of tube feeding in patients with Alzheimer's is essential for nurses and caregivers to provide safe and effective care. Proper positioning, monitoring for signs of aspiration, ensuring tube patency, and following feeding protocols can help prevent complications and promote the well-being of patients with Alzheimer's who require tube feeding.

Correct Answer: C

Rationale: In this scenario, the correct answer is C) 12 months. This is because most states require nursing assistants to renew their certification every 12 months by completing a specified number of continuing education hours and working a minimum number of paid hours within that time frame. Option A) 16 months is incorrect because it exceeds the typical certification renewal period for nursing assistants. Option B) 24 months is also incorrect as it is longer than the standard certification renewal period. Option D) 36 months is incorrect as it extends beyond the typical timeframe for certification renewal. From an educational perspective, understanding the certification renewal requirements for nursing assistants is crucial for maintaining compliance with state regulations and ensuring the delivery of safe and competent care to patients, especially those with Alzheimer's disease. By selecting the correct answer, learners demonstrate their grasp of the necessary timeframe for certification renewal, which is essential for their professional development and the quality of care they provide.

Correct Answer: B

Rationale: The correct answer is B) Assess for the presence of anxiety, pain, or fatigue. This is the best next step because the patient's inability to perform leg exercises correctly could be due to underlying issues such as anxiety, pain, or fatigue. By assessing for these factors, the nurse can address the root cause of the problem and provide appropriate interventions to help the patient perform the exercises effectively. Option A) Encouraging the patient to practice at a later date may not address the underlying issue causing the incorrect performance of leg exercises. It is important to assess the patient first before suggesting further practice. Option C) Asking the patient why exercises are not being done may not reveal the underlying factors contributing to the incorrect performance of leg exercises. Direct questioning may not always yield accurate information. Option D) Evaluating the educational methods used to educate the patient is important but should come after addressing any immediate issues that may be hindering the patient from performing the exercises correctly. It is essential to prioritize assessing the patient's current condition first. In an educational context, this scenario highlights the importance of thorough assessment in patient care. Understanding the reasons behind a patient's inability to perform a task is crucial in providing individualized and effective care. It also emphasizes the need for nurses to look beyond surface-level observations and consider holistic factors that may impact a patient's ability to follow through with prescribed treatments or exercises.

Correct Answer: A

Rationale: In this scenario, the nurse should see the patient who had cataract surgery and is coughing first. The rationale behind this choice is based on the principle of ABC prioritization in nursing - Airway, Breathing, Circulation. Coughing could indicate a potential airway obstruction or respiratory distress, which requires immediate attention to ensure the patient's airway is clear and their breathing is adequate. The other options are not the priority because they do not pose an immediate threat to the patient's life or well-being. The patient who had vascular repair of the right leg not doing leg exercises may need encouragement and reinforcement of the importance of the exercises but does not require immediate attention. The patient after knee surgery with compression devices and heparin is stable and following the standard post-operative care protocol. The patient with vital signs taken at specific intervals is also stable and does not require immediate intervention. From an educational perspective, this question helps students understand the importance of prioritizing patient care based on the urgency of the situation. It reinforces the concept of triaging patients based on their condition and the potential risks involved. Understanding the rationale behind prioritization in nursing care is crucial for providing safe and effective patient care.
