Question 1 of 5
It is considered as the bluntly rounded portion of the heart
Correct Answer: D
Rationale: The apex is the bluntly rounded portion of the heart located at the bottom. It is formed by the tip of the left ventricle and points slightly downward and to the left. The apex is essential in detecting the point of maximum intensity of the heartbeat, known as the apical impulse or point of maximal impulse (PMI). This is where the heart beats closest to the chest wall and can be felt or heard during a physical examination. The base of the heart, on the other hand, is the broader superior part of the heart where the major blood vessels enter and exit. The pericardium is the tough sac enclosing the heart, and the aorta is the main artery that carries oxygen-rich blood from the heart to the body.
Question 2 of 5
An infant with tetralogy of Fallot becomes cyanotic and dyspneic after a crying episode. To relieve the cyanosis and dyspnea, the nurse should place the infant in the:
Correct Answer: A
Rationale: The orthopneic position is the best position to relieve cyanosis and dyspnea in an infant with tetralogy of Fallot. This position involves sitting up and leaning forward, which helps improve lung expansion and oxygenation. Placing the infant in the orthopneic position will reduce the workload on the heart, improve oxygenation, and relieve symptoms of cyanosis and dyspnea associated with tetralogy of Fallot. It allows for better expansion of the lungs and improves ventilation-perfusion matching, thereby enhancing oxygen exchange and alleviating the cyanotic spell.
Question 3 of 5
The nurse is teaching the parent of a child newly diagnosed with JRA. The nurse would evaluate the teaching as successful when the parent is able to say that the disorder is caused by:
Correct Answer: D
Rationale: The correct answer is D. Juvenile rheumatoid arthritis (JRA) is caused by the immune-stimulated inflammatory response in the joints. In JRA, the body's immune system attacks its own healthy joint tissues, leading to inflammation, pain, and damage to the joints. This chronic inflammation can cause joint stiffness, swelling, and in severe cases, joint deformities. It is not caused by the breakdown of osteoclasts in the joint space (A), the loss of cartilage in the joints (B), or the buildup of calcium crystals in joint spaces (C).
Question 4 of 5
The nurse caring for a 14-year-old girl with DI understands which of the following about this disorder?
Correct Answer: C
Rationale: Diabetes Insipidus (DI) is a condition characterized by the inability of the kidneys to conserve water, leading to excessive thirst and excretion of large volumes of dilute urine. Central DI, the most common form in children, is treated with a synthetic form of the hormone vasopressin, also known as desmopressin. Vasopressin helps the kidneys to retain water, thereby reducing urine output and preventing excessive dehydration. Since DI is a chronic condition, treatment with vasopressin is typically required on a lifelong basis to manage symptoms and prevent complications. It is important for healthcare providers to understand the long-term nature of DI treatment in order to provide appropriate care and support to patients with this condition.
Question 5 of 5
a newborn has a meningomyelocele; the nurse should place him in which position:
Correct Answer: C
Rationale: A newborn with meningomyelocele should be placed in a prone position to prevent trauma or pressure on the lesion. Placing the newborn in the prone position helps prevent the lesion from coming in contact with surfaces and reduces the risk of infection and injury. By positioning the newborn prone, gravity will assist in closing the lesion and reducing the risk of complications. It is crucial to follow this positioning guideline to ensure the infant's safety and well-being.
