An adolescent brings a physician's note to school stating that he is not to participate in sports due to a diagnosis of Osgood-Schlatter disease. Which of the following statements about the disease is correct?

Correct Answer: C

Rationale: Osgood-Schlatter disease occurs in adolescents during the rapid growth phase when the infrapatellar ligament of the quadriceps muscle pulls on the tibial tubercle, causing pain and swelling in the inferior aspect of the knee. The condition is commonly caused by activities that require repeated use of the quadriceps, such as track and soccer. Choice A is incorrect because Osgood-Schlatter disease is not specifically linked to competitive swimming. Choice B is incorrect as surgical intervention is not usually necessary for this condition. Choice D is incorrect as the student is not trying to avoid physical education but is restricted from participating in sports due to the diagnosis of Osgood-Schlatter disease.

Correct Answer: C

Rationale: The correct answer is 'Developmental milestones may be slightly delayed but usually will require no additional intervention.' This statement is incorrect as delayed developmental milestones in a child with cerebral palsy require interventions and constant follow-ups. Developmental monitoring is essential to track a child's growth and development over time. If any concerns are raised during monitoring, a developmental screening test should be conducted promptly to address any developmental delays or issues. Regular interventions, therapies, and support are crucial to optimize the child's development and well-being. Therefore, it is important for parents to be aware that additional interventions may be necessary to support their child's development.

Correct Answer: A

Rationale: The correct answer is that Duchenne is an X-linked recessive disorder, meaning the affected gene is located on one of the two X chromosomes of a female carrier. If a son receives the X chromosome bearing the gene, he will develop the disease, giving him a 50% chance of being affected. Daughters, on the other hand, are not affected by Duchenne but have a 50% chance of being carriers since they inherit one copy of the defective gene from the mother. The other X chromosome is inherited from the father, who cannot be a carrier. Therefore, choice A is accurate. Choice B is incorrect because daughters do not develop the disease, and sons have a 50% chance of developing, not both having a 50% chance. Choice C is incorrect as it does not consider the X-linked inheritance pattern of Duchenne. Choice D is inaccurate as it incorrectly states that only sons have a 25% chance of developing the disorder, omitting the carrier status of daughters.

Correct Answer: D

Rationale: The correct answer is 'Risk for infection.' When membranes are ruptured for over 24 hours before delivery, there is a significantly increased risk of infection for both the mother and the newborn. Factors such as increased local cytokines, an imbalance in enzyme activity, and increased intrauterine pressure contribute to this risk. 'Altered tissue perfusion' is not the priority in this scenario as there is no indication of compromised blood flow. 'Risk for fluid volume deficit' is not the priority as there are no signs of excessive fluid loss. 'High risk for hemorrhage' is not the priority as the question does not suggest active bleeding as an immediate concern.

Correct Answer: A

Rationale: A non-rebreather mask is used for supplemental oxygen delivery for clients experiencing breathing difficulties. The non-rebreather mask includes a one-way valve that allows exhaled air to escape, preventing the rebreathing of carbon dioxide. The client inhales oxygenated air from a reservoir bag attached to the mask, providing high-concentration oxygen therapy. A non-rebreather mask can deliver FiO2 levels of up to 90%, making it an effective intervention for clients requiring high oxygen concentrations. Therefore, the statement that 'A non-rebreather can provide an FiO2 of 40%' is correct. Choices B, C, and D are incorrect because clients should breathe through their nose and mouth, the mask offers a reservoir for inhaling oxygen, and the mask should be assessed and potentially replaced if soiled or damaged, not routinely changed every 3 hours.
