During an adolescent examination, the nurse asks a 13-year-old female to bend forward at the waist with arms hanging freely. Which of the following assessments is the nurse most likely conducting?

Correct Answer: D

Rationale: The correct answer is scoliosis. During the assessment for scoliosis, the nurse asks the adolescent to bend forward at the waist with arms hanging freely to observe for any lateral deviation of the spine, uneven rib levels, or asymmetry. This assessment is a routine part of an adolescent examination, especially in females, as scoliosis is more common in this population. Choices A, B, and C are incorrect. Spinal flexibility is usually assessed through different maneuvers, leg length disparity is evaluated by measuring the length of the legs, and hypostatic blood pressure refers to a decrease in blood pressure due to immobility.

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.

Correct Answer: A

Rationale: A remittent fever is characterized by temperature fluctuations where the fever spikes and then lowers but does not return to normal temperature. Option A best describes this pattern of fever. Option B describes a pattern of fever known as a biphasic fever, where the fever alternates between days of fever and normal temperature. Option C describes a pattern of fever that is more indicative of an intermittent fever, where the fever lasts for a specific duration followed by an interval of normal temperature. Option D does not accurately describe a remittent fever, as it suggests a persistent fever that has lasted over 24 hours, which is not specific to the remittent pattern.
