Correct Answer: A

Rationale: The correct answer is A because shortness of breath with minimal exertion indicates possible respiratory distress, which can be a sign of significant lung damage from smoking. This symptom suggests a decreased ability to exchange oxygen and carbon dioxide efficiently, potentially leading to serious health complications. Choice B is incorrect because an occasional cough with mucus production is common in smokers and may not be as alarming as shortness of breath. Choice C is incorrect as slight wheezing after physical activity could be due to exercise-induced asthma rather than solely smoking-related issues. Choice D is incorrect because even though the patient may not be experiencing symptoms related to smoking currently, it does not rule out potential underlying lung damage or future health risks associated with smoking.

Correct Answer: C

Rationale: The correct answer is C: Use less force to percuss over the abdomen. When percussing an obese patient's abdomen, more force may not be effective due to the increased tissue thickness. Using less force allows for better transmission of sound waves through the tissues, improving the nurse's ability to assess for changes in sound. Asking the patient to take deep breaths (choice A) may help relax the abdominal muscles but won't address the issue of increased tissue thickness. Considering it a normal finding (choice B) without attempting to improve assessment techniques could lead to missed abnormalities. Using more force (choice D) can be uncomfortable for the patient and may still not produce clear sounds due to the tissue barrier.

Correct Answer: A

Rationale: The correct answer is A: Blood pressure and heart rate. This is crucial in assessing the cardiac function of a patient with a history of myocardial infarction. Monitoring blood pressure and heart rate helps in evaluating cardiovascular status and detecting any potential complications. Abnormal values in these parameters can indicate inadequate perfusion to the heart or other organs, which can be life-threatening. Other choices are incorrect because: B: Temperature and respiratory rate are important assessments but not the priority for a patient with a history of myocardial infarction. C: Bowel sounds and abdominal girth are more relevant for gastrointestinal issues and not a priority in this scenario. D: Urine output and skin integrity are important assessments for overall health but do not directly relate to the cardiovascular status in a patient with a history of myocardial infarction.

Correct Answer: B

Rationale: The correct answer is B: Deep vein thrombosis (DVT). Post-operative hip replacement patients are at high risk for DVT due to immobility and surgical trauma. The nurse should monitor for signs such as swelling, redness, and pain in the affected leg. DVT can lead to serious complications like pulmonary embolism if not detected early. Choices A, C, and D are incorrect because while pneumonia, wound infection, and hypoglycemia are also potential post-operative complications, they are not as directly associated with hip replacement surgery as DVT.

Correct Answer: C

Rationale: The correct answer is C: Patient's level of consciousness. Assessing the patient's level of consciousness is crucial in a neurological assessment as it provides immediate information on the overall function of the brain. Changes in consciousness can indicate serious neurological issues such as head injuries or stroke. It is essential to prioritize assessing consciousness first to determine the urgency of the situation. Assessing reflexes (A), cranial nerve function (B), and pupil response (D) are also important in a neurological assessment but come after assessing the patient's level of consciousness, as they provide more specific and detailed information about the neurological status.
