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: 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: B

Rationale: In a hospitalized patient on prolonged bed rest, the most likely cause of sudden onset shortness of breath and chest pain is pulmonary embolism. Pregnancy and prolonged inactivity both increase the risk of clot formation in the deep veins of the legs, known as deep vein thrombosis (DVT). These clots can dislodge and travel to the lungs, causing a pulmonary embolism. Myocardial infarction (Choice A) is less likely in a young patient without a significant history of atherosclerosis. Anxiety attacks (Choice C) may present with similar symptoms but are less likely in this context. Congestive heart failure (Choice D) is less probable given the acute onset of symptoms and absence of typical signs like peripheral edema in this case.

Correct Answer: A

Rationale: A family history of heart disease is an inherited risk factor for developing atherosclerosis. This factor is not modifiable through lifestyle changes. Studies have shown that having a first-degree relative with heart disease significantly increases the individual's risk of developing atherosclerosis. Overweight, smoking, and age are not hereditary risk factors for atherosclerosis. Overweight and smoking are lifestyle-related risk factors, while age is a non-modifiable risk factor that increases with time but is not directly inherited.
