A teenaged male patient who is on a wrestling team is examined by the nurse in the clinic. Which assessment finding would prompt the nurse to teach the patient about the importance of not sharing headgear to prevent the spread of pediculosis?

Correct Answer: B

Rationale: The correct answer is B because papular, wheal-like lesions with white deposits on the hair shaft are characteristic of pediculosis (lice infestation). The white deposits are lice eggs (nits) attached to the hair shaft, indicating the presence of lice. This finding would prompt the nurse to teach the patient about the importance of not sharing headgear to prevent the spread of lice. Sharing headgear can facilitate the transmission of lice from one person to another. Choice A is incorrect as ring-like rashes with red, scaly borders over the entire scalp are more indicative of ringworm (tinea capitis), a fungal infection, not pediculosis. Choice C is incorrect as patchy areas of alopecia with small vesicles and excoriated areas are more indicative of scalp folliculitis or herpes zoster, not pediculosis. Choice D is incorrect as red, hive-like papules and plaques with sharply circumscribed borders are

Correct Answer: A

Rationale: The correct answer is A: a fluid-filled sac found at some joints. Bursitis is an inflammation of the bursa, which is a fluid-filled sac located near joints that helps reduce friction between bones, tendons, and muscles. The bursa can become inflamed due to overuse, trauma, or infection, leading to pain and swelling. Choices B, C, and D are incorrect because bursitis specifically involves the bursa, not the synovial membrane, connective tissue, or fibrocartilage within the joint. It is essential for the nurse to accurately explain the condition to the patient to ensure understanding and proper management.

Correct Answer: A

Rationale: The correct answer is A because having a pacemaker can pose a significant risk during an MRI due to potential interference with the device's function. Pacemakers can malfunction or heat up during the MRI procedure, leading to serious complications. Consulting with the healthcare provider is crucial to determine if special precautions or alternative imaging methods are needed. Choices B, C, and D are incorrect because: B: Claustrophobia can be managed with medication or relaxation techniques, and open MRI machines are available for claustrophobic patients. C: Hearing aids are generally safe during an MRI, and can be removed before the procedure if necessary. D: Allergies to shellfish do not pose a direct risk during an MRI unless contrast dye containing shellfish is used, in which case alternative contrast agents can be used.

Correct Answer: B

Rationale: The correct answer is B: "You will begin work with a physical therapist tomorrow." This is the correct answer because early physical therapy is crucial for restoring range of motion and strength after rotator cuff surgery. The therapist will guide the patient in exercises to prevent stiffness and promote healing. Choice A is incorrect as it is overly pessimistic and does not reflect the potential for recovery with proper rehabilitation. Choice C is incorrect because immobilizing the shoulder for too long can lead to stiffness and reduced range of motion. Choice D is incorrect as the drop-arm test is used to assess rotator cuff tears before surgery, not to determine the success of surgery.

Correct Answer: A

Rationale: The correct answer is A: Assess for hip pain. This is because evaluating the patient's level of hip pain is a crucial indicator of the effectiveness of Buck's traction in managing the intracapsular fracture of the right femur. Decreased pain can suggest proper alignment and traction application. Checking peripheral pulses (B) is important for assessing circulation but not specific to evaluating traction. Assessing for contractures (C) is relevant for long-term care but not immediate effectiveness. Monitoring for hip dislocation (D) is important but not the primary indicator of traction effectiveness.
