Correct Answer: D

Rationale: The correct answer is D: Anxiety. Repetitive behaviors in OCD serve as a way for individuals to cope with their anxiety. These behaviors are often performed to reduce the distress caused by obsessive thoughts. Choice A, fearful situations, is incorrect because the behaviors are more related to managing anxiety rather than fear itself. Choice B, depression, is incorrect as OCD behaviors are not typically a method of coping with depression. Choice C, delusions, is also incorrect as these behaviors are not aimed at managing delusional thoughts but rather anxiety in OCD.

Correct Answer: A

Rationale: The correct answer is changing a colostomy bag. This task falls within the LPN's scope of practice. LPNs are trained to provide basic nursing care, including assisting with activities of daily living and certain medical procedures like changing ostomy bags. Hanging a new bag of TPN and drawing a peak antibiotic blood level from a central line are tasks that require a higher level of training and are typically performed by RNs due to their complexity and potential risks. Administering IV pain medication to a two-day post-op client is usually the responsibility of an RN as it involves close monitoring, assessment of the client's condition, and the administration of potent medications that require a higher level of clinical judgment and expertise.

Correct Answer: B

Rationale: Engaging in an aerobic exercise class every day is crucial in reducing the risk of coronary heart disease. Aerobic exercises help keep the heart in shape, lower blood pressure, and improve cholesterol levels. It is recommended to participate in at least 150 minutes of moderate-intensity aerobic exercise per week, which can be achieved by engaging in aerobic exercise daily. Choice A has been corrected to emphasize the frequency required to significantly reduce the risk of coronary heart disease. Choice C has been modified to suggest moderation in alcohol intake, as excessive alcohol consumption is harmful. Choice D is also incorrect as a balanced diet, not specifically high-protein, high-fat, is recommended to reduce the risk of coronary heart disease and maintain a healthy weight.

Correct Answer: D

Rationale: The correct action for the nurse to take next is to notify the physician immediately (stat). The client's symptoms of foot pain, pulselessness, pallor, and cold extremity suggest a potential vascular complication, such as arterial occlusion. Prompt notification of the physician is crucial as this condition requires urgent intervention to restore blood flow and prevent tissue damage. Administering an anticoagulant (Choice A) without physician evaluation could be harmful as the underlying cause needs to be determined first. Warming the room and re-assessing (Choice B) may delay necessary treatment. Increasing IV fluids (Choice C) is unlikely to address the urgent vascular issue indicated by the symptoms described.

Correct Answer: A

Rationale: The client presenting with recurring crushing chest pain should be seen first as this symptom could indicate a myocardial infarction (MI), which is a life-threatening condition requiring immediate attention. Assessing and managing potential cardiac issues take priority over other concerns like needing an IV for surgery, pain control post-hysterectomy, or assistance with mobility. While all clients require care, addressing the chest pain promptly is crucial to ensure the client's safety and well-being.
