A patient with chronic respiratory failure secondary to severe restrictive lung disease requires long-term oxygen therapy to maintain adequate oxygenation. Which of the following oxygen delivery devices is most appropriate for delivering continuous supplemental oxygen in this patient?

Correct Answer: D

Rationale: The most appropriate oxygen delivery device for a patient with chronic respiratory failure secondary to severe restrictive lung disease requiring continuous supplemental oxygen is a non-rebreather mask. A non-rebreather mask is designed to deliver high-flow oxygen and is typically used for short-term medical treatment in emergency situations or for critically ill patients. It is ideal for providing the highest concentration of oxygen available for inhalation, making it suitable for patients with severe hypoxemia.

Correct Answer: C

Rationale: The main source of nutrition for the baby during pregnancy is the placenta. The placenta is an organ that develops inside the uterus during pregnancy and provides essential nutrients and oxygen from the mother's blood to the baby through the umbilical cord. It acts as a barrier, protecting the baby from harmful substances while allowing necessary nutrients to pass through. The amniotic fluid serves as a protective cushion for the baby, the uterus provides the space for the baby to grow, and chorionic villi are small, hair-like structures on the placenta that aid in the exchange of nutrients and waste between the mother and the baby. However, the primary source of nutrition for the baby is the placenta, making option C the correct answer in this scenario.

Correct Answer: A

Rationale: Sherry is a type of fortified wine produced in Spain. It is not associated with the development of hyperkalemia, which is a condition characterized by high levels of potassium in the blood. Hyperkalemia is commonly caused by kidney dysfunction, certain medications, or excessive intake of potassium-rich foods. Drinking Sherry is not likely to cause hyperkalemia. On the other hand, Sherry consumption can potentially contribute to tooth decay, gastric ulcers, and rectal bleeding due to its acidity and alcohol content.

Correct Answer: D

Rationale: Upon clinical assessment, the nurse observes that the outstanding manifestation of the patient is edema. Edema is characterized by the accumulation of excess fluid in the body's tissues, leading to swelling. Edema can be a sign of various health conditions, such as heart failure, kidney disease, liver disease, or injury. It is crucial to identify and address the underlying cause of edema promptly to prevent complications and provide appropriate treatment for the patient.

Correct Answer: D

Rationale: A delimitation in a research study refers to setting specific boundaries or restrictions on the scope of the study. In this scenario, Gloria's decision to include only nurses with a minimum of three years experience as psychiatric nurses is a delimitation because it sets a specific criterion or boundary for the selection of participants. This helps to focus the study on a particular group of individuals who possess the required experience, ensuring the research is targeted and relevant to the topic being investigated.

Correct Answer: A

Rationale: ORNAP stands for Operating Room Nurses Association of the Philippines, which is an appropriate professional organization for Merle to actively join after 3 years of experience in the Operating Room. ORNAP is dedicated to promoting professional growth and development, advancing the standards of perioperative nursing practice, and providing a platform for networking and collaboration among operating room nurses in the Philippines. By becoming a member of ORNAP, Merle can stay updated on the latest trends and best practices in perioperative nursing, participate in continuing education opportunities, and connect with colleagues in the same field to enhance her skills and knowledge.

Correct Answer: C

Rationale: The symptoms described, including progressive weakness, muscle atrophy, fasciculations, dysphagia, and dysarthria primarily involving the upper and lower extremities, are classic features of amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease. ALS is a progressive neurodegenerative disorder that affects the motor neurons in the brain and spinal cord, leading to muscle weakness and atrophy. As the disease progresses, patients may develop difficulty swallowing (dysphagia) and speaking (dysarthria). In contrast, Parkinson's disease primarily involves movement-related symptoms such as tremors, muscle stiffness, and slow movements. Guillain-Barré syndrome (GBS) is an acute inflammatory demyelinating polyneuropathy that typically presents with ascending weakness and sensory abnormalities, often preceded by an infection. Myasthenia gravis is characterized by muscle weakness exacerbated by

Correct Answer: B

Rationale: Benign prostatic hyperplasia (BPH) is a condition characterized by an abnormal enlargement of the prostate gland, which is non-cancerous. This enlargement can lead to lower urinary tract symptoms such as urinary hesitancy (difficulty starting the urine stream), weak urinary stream, incomplete bladder emptying, frequent urination, urgency, and nocturia. BPH is a common condition in aging men and is not usually associated with prostate cancer. Other conditions like prostate cancer, prostatitis, and prostate adenoma may present with similar symptoms, but BPH is specifically characterized by the non-cancerous enlargement of the prostate gland. Treatment for BPH may include medications to improve symptoms or surgical procedures to reduce the size of the prostate gland.

Correct Answer: A

Rationale: Betamethasone (Celestone) is a corticosteroid medication that is commonly used to promote fetal lung maturity in pregnant women at risk of preterm delivery. Administering betamethasone to the mother helps accelerate the production of surfactant in the fetal lungs, which is essential for proper lung function and development. This medication is typically given to pregnant women between 24 and 34 weeks of gestation to reduce the risk of respiratory distress syndrome in preterm infants. It does not prevent premature closure of the ductus arteriosus, delay delivery, or stop premature uterine contractions.
