A 60-year-old woman is undergoing a mammogram. The nurse explains that the procedure is done to:

Correct Answer: A

Rationale: The correct answer is A because mammograms are specifically designed to detect abnormal growths or tumors in the breast tissue, particularly in the early stages of breast cancer. This is crucial for early detection and effective treatment. Choice B is incorrect because mammograms are not used to identify changes in hormone levels. Choice C is incorrect because mammograms do not evaluate lung function related to breast cancer. Choice D is incorrect because mammograms do not assess for signs of osteoporosis; a bone density scan is typically used for that purpose.

Correct Answer: B

Rationale: The correct answer is B: Providing a source of fast-acting carbohydrate. In a hypoglycemic episode, the priority is to raise the blood sugar quickly to prevent further complications. Fast-acting carbohydrates such as glucose tablets or orange juice can rapidly increase blood sugar levels. Administering insulin (choice A) can further lower blood sugar, checking blood glucose levels (choice C) may delay treatment, and contacting the healthcare provider (choice D) is not necessary in the immediate management of hypoglycemia.

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: C

Rationale: The correct answer is C. After a stroke, patients need to be evaluated by a healthcare professional before resuming driving. This is crucial to ensure the safety of the patient and others on the road. Choice A shows medication compliance, B demonstrates follow-up care, and D emphasizes monitoring symptoms, all of which are essential post-stroke. However, choice C indicates a lack of understanding about the importance of medical clearance before driving, hence the need for further education.

Correct Answer: A

Rationale: The correct answer is A: Quadriceps setting exercises. These exercises help prevent complications by strengthening the quadriceps muscles, which are crucial for knee stability and joint support post-surgery. They also aid in preventing muscle atrophy and promoting blood circulation. Leg lifts with weights (B) may strain the knee joint, leading to complications. Isometric muscle contractions (C) involve static muscle contractions and do not provide the necessary range of motion needed post-knee surgery. Active range-of-motion exercises (D) may be beneficial but should be performed after quadriceps setting exercises to avoid unnecessary strain on the knee joint.
