When performing a physical assessment, palpation reveals to the clinic nurse that a client has an enlarged thyroid gland. What action should the nurse take in response to this finding?

Choice A Reason:
History of a fractured patella is incorrect. While a history of a fractured patella may lead to some degree of crepitation in the knee joint, especially if there was damage to the articular surfaces during the injury, it is less likely to cause widespread crepitation with joint movement. Crepitation associated with a fractured patella would typically be localized to the site of injury rather than throughout the joint.
Choice B Reason:
Knee arthroplasty surgery is incorrect. Knee arthroplasty surgery involves the replacement of a damaged knee joint with an artificial prosthesis. While crepitation can occur in some cases following knee arthroplasty, it is less likely to be the cause of crepitation observed in this scenario, especially if the client's knee arthroplasty was successful and without complications.
Choice C Reason:
Degenerative disease is correct. Degenerative disease of the knee joint, such as osteoarthritis, is a common cause of crepitation during joint movement. Osteoarthritis is characterized by the breakdown of cartilage in the joints, leading to friction between bones and resulting in crepitus. This condition is often associated with aging, repetitive stress on the joints, or underlying joint abnormalities.

Choice D Reason:
Needle aspiration of the synovial space is incorrect. Needle aspiration of the synovial space is a procedure performed to remove excess fluid or to obtain a sample of synovial fluid for diagnostic purposes. While this procedure may be performed for various reasons, it is not directly associated with crepitation in the knee joint.

Choice A Reason:
Assessing conjunctival sacs of lower lids for pallor is incorrect. Pallor of the conjunctival sacs, or inner eyelids, may indicate anemia or decreased blood flow. While it can be a sign of various health conditions, it is not specific to jaundice. Jaundice is characterized by yellowing of the skin and sclerae (the white part of the eyes) due to elevated bilirubin levels in the blood, so assessing for pallor would not directly confirm jaundice.
Choice B Reason:
Observing the client's urine for dark orange color is incorrect. Dark orange urine may indicate concentrated urine or dehydration, but it is not specific to jaundice. Jaundice primarily manifests as yellowing of the skin and sclerae due to elevated bilirubin levels, rather than a change in urine color. While changes in urine color may occur in certain liver conditions, such as obstructive jaundice, it is not the most direct or reliable method to confirm jaundice.
Choice C Reason:
Examining client's sclera for icterus is correct. Icterus, or yellowing of the sclerae (the white part of the eyes), is a classic sign of jaundice. Elevated levels of bilirubin in the blood lead to the yellow discoloration of the sclerae, providing a direct visual confirmation of jaundice. Examining the sclerae for icterus is a quick and reliable method to confirm jaundice during a physical assessment.
Choice D Reason:
Reviewing recent serum bilirubin levels is incorrect. Reviewing recent serum bilirubin levels can provide objective data on bilirubin levels in the blood, which may support the diagnosis of jaundice. Elevated serum bilirubin levels are characteristic of jaundice. While this option provides valuable information, it may not be immediately available during a physical assessment and does not directly confirm jaundice visually, unlike examining the sclerae for icterus.
