when a female carrier of hemophilia marries a male who is free of the disease, the risk to their off spring for each pregnancy is what:

Correct Answer: B

Rationale: Hemophilia is an X-linked recessive genetic disorder, meaning it is carried on the X chromosome. Females have two X chromosomes, while males have one X and one Y chromosome. In this scenario, the female carrier has one X chromosome with the hemophilia gene and one normal X chromosome. When she has children, she has a 50% chance of passing on the X chromosome with the hemophilia gene to her sons. Therefore, half the male children will inherit hemophilia, while half will not. Daughters, on the other hand, have a 50% chance of inheriting the X chromosome with the hemophilia gene but since it is a recessive disorder, they will be carriers of hemophilia rather than having the disease itself.

Correct Answer: C

Rationale: Systematic lupus erythematosus (SLE) is an autoimmune disease that primarily attacks various tissues and organs in the body, including the skin, joints, kidneys, and nervous system. In particular, SLE can affect the peripheral nervous system, leading to symptoms such as neuropathy, mononeuritis multiplex, and other neurological manifestations. Therefore, among the given options, the nerve is the tissue primarily targeted by SLE.

Correct Answer: D

Rationale: Asking the child to draw a picture can be the most helpful technique in this situation because it allows the child to express themselves visually, especially when verbal communication may be challenging. Drawing can serve as a form of communication that the child may find more comfortable and engaging. It provides the child with a non-verbal way to express their thoughts, feelings, and experiences, which can help the nurse better understand the child's perspective and potentially build a connection with them. Additionally, examining the child's drawings can provide valuable insights into their emotional state and concerns, facilitating more effective care and support.

Correct Answer: C

Rationale: Thalassemia major is a genetic disorder characterized by abnormal hemoglobin production. Individuals with thalassemia major require frequent blood transfusions to manage their anemia, leading to iron overload in the body. Over time, this excess iron can accumulate in various organs such as the liver, heart, and endocrine glands, causing damage and dysfunction. This condition is known as hemochromatosis. Long-term complications of hemochromatosis include liver cirrhosis, heart failure, diabetes, and endocrine disorders. Therefore, the long-term complications seen in thalassemia major are primarily associated with hemochromatosis rather than anemia, growth retardation, or splenomegaly.

Correct Answer: A

Rationale: Pursed lip breathing is a breathing technique commonly used to help improve breathing efficiency in individuals with respiratory conditions such as chronic obstructive pulmonary disease (COPD). By pursing the lips during exhalation, it creates back pressure that helps to keep the airways open longer. This results in slower and more controlled expiration, allowing the individual to exhale a smaller volume of air while maintaining adequate oxygen exchange. This can reduce the feeling of dyspnea (difficulty breathing) and help improve oxygen saturation levels in the blood.
