A nurse is planning a teaching session for parents of preschool children. Which statement explains why the nurse should include information about morbidity and mortality?

Correct Answer: D

Rationale: Including information about morbidity and mortality is important in a teaching session for parents of preschool children because it helps identify high-risk age groups for certain disorders or hazards. By understanding which age groups are more vulnerable to specific health issues, parents can take proactive steps to protect their children and promote their overall well-being. This information also enables parents to recognize signs and symptoms early on, leading to timely interventions and better outcomes for their children's health.

Correct Answer: C

Rationale: Leukemia is a type of cancer that affects the blood and bone marrow, leading to an overproduction of abnormal white blood cells. The symptoms of leukemia can include fatigue, weakness, weight loss, frequent infections, fever, bruising or bleeding easily, and bone pain. Given the vague presenting symptoms and the potential involvement of multiple bodily systems, leukemia is a condition that should be suspected and investigated further. Anemia, rheumatic arthritis, and systematic lupus erythematosus can also present with some similar symptoms, but for the given scenario, leukemia is the most probable condition to suspect.

Correct Answer: D

Rationale: The Tensilon test is used to confirm the diagnosis of myasthenia gravis, a condition characterized by muscle weakness and fatigue. In this test, the medication Tensilon (also known as edrophonium) is administered intravenously. If the patient has myasthenia gravis, there will be a rapid but temporary improvement in muscle strength after the Tensilon injection. This response helps to differentiate myasthenia gravis from other causes of muscle weakness. The other options mentioned (Mestinon test, pulmonary function studies, and quinine tolerance test) do not specifically confirm the diagnosis of myasthenia gravis.

Correct Answer: A

Rationale: Deferoxamine is a chelating agent used to treat iron overload in patients such as those with thalassemia. One of the serious side effects of deferoxamine is ototoxicity, which can manifest as decreased hearing or ringing in the ears. Therefore, if a child with thalassemia who is taking deferoxamine experiences a decrease in hearing, the nurse should promptly notify the physician for further evaluation and possible adjustment of the treatment plan to prevent further hearing damage. Hypertension, red urine, and vomiting are possible side effects of deferoxamine, but decreased hearing is the most concerning side effect that requires immediate attention due to the risk of permanent damage.

Correct Answer: A

Rationale: In a normal healthy individual, the rate of the radial pulse (peripheral pulse) and the heart rate (apical pulse) should be the same. This is because each heartbeat should result in a corresponding pulse felt at the radial artery in the wrist. The pulse is generated by the heart's contraction and the subsequent ejection of blood into the arteries, causing a wave of pressure that can be felt as the pulse. Therefore, in a healthy individual, the radial pulse rate should match the heart rate. If there is a significant difference between the two rates, it may indicate a cardiovascular abnormality or other underlying health condition that warrants further investigation.
