The nurse is educating the patient about synovial joints in the body. Which joint can be included in this teaching? Select all that apply.

A. White flakes that are easily removed from hair shaft: This description is characteristic of seborrheic dermatitis or dandruff rather than Pediculosis humanus capitis. Lice nits are firmly cemented to the hair shaft by a chitinous substance and cannot be flicked or blown away. Ease of removal is a primary clinical differentiator from an active infestation.

B. Patchy bald spots over the scalp: Alopecia areata or tinea capitis typically cause localized hair loss and circular bald patches. While scratching from lice can cause secondary excoriation, it does not typically result in discrete areas of hair loss. Bald spots suggest a fungal infection or an autoimmune process rather than parasites.

C. Light brown colored dots attached to hair at nape of neck: These represent nits, which are the eggs of head lice, frequently found in warm areas like the nape of the neck or behind ears. Their firm attachment to the hair shaft and proximity to the scalp are definitive diagnostic markers. Identifying these is the standard for confirming a lice infestation.

D. Thick yellow crusts on the scalp: This finding is most often associated with "cradle cap" or severe seborrheic dermatitis, which involves an overproduction of sebum. It is an inflammatory skin condition rather than a parasitic infestation. While it may cause itching, it lacks the specific presence of nits or live lice.

D. Handwashing: This is the initial step to ensure infection control and prevent the transmission of nosocomial pathogens. It must precede any physical contact with the patient's integument or environment. Maintaining aseptic technique is fundamental to all nursing physical examination protocols.

C. Inspecting for position: Inspection provides visual data on patient distress or abdominal contour without disturbing the viscera. This non-invasive step allows the nurse to observe for signs of peritonitis, such as lying perfectly still. It must be performed before any manual manipulation of the abdomen.

F. Auscultating for bowel sounds: Auscultation follows inspection to ensure that bowel sounds are not artificially altered by manual manipulation or palpation. This sequence prevents the elicitation of false hyperactive or hypoactive sounds. It provides a baseline for peristaltic activity before the abdomen is touched.

E. Palpating lightly: Light palpation identifies areas of muscular guarding and superficial masses while minimizing patient discomfort. This step precedes deep palpation to prevent premature elicitation of severe pain. It helps localize the area of maximal tenderness mentioned in the clinical presentation.

B. Palpating for rebound tenderness: Deep palpation for rebound tenderness is performed last because it often causes significant pain and distress. This is a specific assessment for peritoneal irritation often seen in clinical cases of appendicitis. It provides the final physical evidence of an acute abdominal process.

A. Notifying the health care provider: Communication of findings to the physician is the final step after a comprehensive assessment is documented. This allows the nurse to provide a complete clinical picture, including vital signs and specific abdominal findings. Timely reporting facilitates urgent surgical or medical intervention.
