Correct Answer is B
Explanation
A. Enlarged lymph nodes are associated with hypertensive heart disease is not a correct association. Hypertension does not directly cause lymph node enlargement.
B. They are most likely enlarged as a result of the throat infection is the correct answer. Enlarged lymph nodes, especially under the jaw, are commonly seen in response to infections, particularly in the throat (such as a viral or bacterial infection like pharyngitis).
C. You should probably see an oncologist to rule out lymphedema is an unnecessary response at this time. Lymphedema usually presents with other symptoms, and the patient's symptoms (fever, sore throat, and localized lymph node enlargement) suggest an infection rather than cancer.
D. You probably have a blockage in the thoracic lymph duct is not a common cause of localized lymph node enlargement. Blockages in the thoracic duct would affect lymphatic flow more generally and would present with more systemic symptoms.
Correct Answer is C
Explanation
A. Having the client take deep breaths is not typically necessary during carotid auscultation. Deep breathing could interfere with the ability to listen to the carotid sounds clearly.
B. Having the client lean forward and turn their head may improve access to the carotid arteries, but it is not the primary recommendation for auscultation.
C. Having the client hold their breath during auscultation is important as it helps eliminate any sounds caused by respiration, allowing the nurse to hear murmurs or bruits more clearly.
D. Coughing before auscultation is unnecessary and would not aid in accurately assessing the carotid arteries.
