A newly diagnosed teenage girl with scoliosis asks the nurse what is Cobb’s angle? You know the nurse’s answer is correct when she says this:

Cobb’s angle is used as a pain management for scoliosis

Cobb’s angle is part of the treatment used to treat scoliosis

Cobb’s angle helps identify teens at risk for scoliosis

Cobb’s angle is the measurement used to evaluate the amount of curvature in the spine

Answer and Explanation

The Correct Answer is D

Choice A reason: Cobb’s angle is not used for pain management in scoliosis. It is a diagnostic measurement of spinal curvature on X-rays, quantifying the degree of lateral deviation. Pain management involves therapies like bracing or surgery, unrelated to this measurement tool.

Choice B reason: Cobb’s angle is not a treatment for scoliosis but a diagnostic tool. It measures the angle of spinal curvature on radiographs to assess severity and guide treatment decisions, such as bracing or surgery, making this statement inaccurate.

Choice C reason: Cobb’s angle does not identify teens at risk for scoliosis but evaluates existing curvature in diagnosed cases. Screening tools, like the forward bend test, identify risk, while Cobb’s angle quantifies confirmed spinal deformity, making this choice incorrect.

Choice D reason: Cobb’s angle is the standard measurement for scoliosis, calculated on X-rays by intersecting lines from the most tilted vertebrae, quantifying lateral spinal curvature in degrees. It determines severity (e.g., mild, moderate, severe) and guides treatment, making this the correct definition.

Correct Answer is B

Explanation

Choice A reason: Hyperkalemia is not typical in bulimia nervosa. Frequent vomiting causes electrolyte loss, particularly potassium, leading to hypokalemia due to hydrogen ion exchange in the kidneys. Hyperkalemia is more associated with renal failure or other conditions, not bulimia’s vomiting-induced losses.

Choice B reason: Dental decay is expected in bulimia nervosa due to frequent self-induced vomiting, which exposes teeth to gastric acid, eroding enamel. This acid exposure, often high in hydrogen ions, demineralizes teeth, causing cavities and sensitivity, a hallmark physical consequence of bulimia’s purging behavior.

Choice C reason: Amenorrhea is more associated with anorexia nervosa, where severe weight loss disrupts hormonal balance, halting menstruation. Bulimia patients often maintain normal weight, so menstrual cycles are typically preserved, making amenorrhea an unlikely finding in this condition.

Choice D reason: Lower than normal body weight is characteristic of anorexia nervosa, not bulimia nervosa, where patients often maintain normal or slightly above-normal weight due to binge-purge cycles. Weight fluctuations occur, but significant underweight status is not typical, unlike in anorexia.

A. Increased length of postoperative care in the health care facility B. Reduced postoperative respiratory function C. Reduced postoperative anxiety D. Increase in postoperative pain

Correct Answer is C

Explanation

Choice A reason: Preoperative teaching aims to optimize recovery, not increase postoperative care duration. By clarifying procedures and expectations, teaching reduces complications, promoting shorter hospital stays, making this outcome contrary to the goals of effective preoperative education.

Choice B reason: Reduced postoperative respiratory function is not a desired outcome. Preoperative teaching, including breathing exercises, aims to enhance respiratory function, preventing complications like atelectasis or pneumonia, making this outcome incorrect for the goals of preoperative education.

Choice C reason: Preoperative teaching reduces postoperative anxiety by educating the client about the procedure, recovery, and expectations, lowering stress hormone release (e.g., cortisol). This promotes psychological preparedness, improving coping and recovery, making it a primary and expected outcome of effective teaching.

Choice D reason: Increased postoperative pain is not an outcome of preoperative teaching. Teaching includes pain management strategies, aiming to reduce pain perception and improve comfort, making this outcome contrary to the educational goal of enhancing postoperative recovery and patient experience.
