A nurse is assessing a client who has myxedema. Which of the following findings should the nurse expect?

Tachycardia.

Diarrhea.

Facial edema.

Heat intolerance.

The correct answer is c) Facial edema.

Answer and Explanation

The Correct Answer is C

Choice A reason:
Tachycardia, or an abnormally rapid heart rate, is not a typical finding in myxedema. Myxedema is associated with hypothyroidism, which usually presents with bradycardia, or a slower than normal heart rate, due to the decreased metabolic demands on the body.
Choice B reason:
Diarrhea is not commonly associated with myxedema. Instead, patients with hypothyroidism and myxedema often experience constipation due to slowed gastrointestinal motility.
Choice C reason:
Facial edema, particularly around the eyes, is a classic sign of myxedema. Myxedema is a severe form of hypothyroidism that can cause mucopolysaccharide deposition in the skin, leading to non-pitting edema. This can be particularly noticeable in the face and periorbital area.
Choice D reason:
Heat intolerance is more commonly associated with hyperthyroidism, not hypothyroidism. Patients with myxedema typically have cold intolerance due to a decrease in basal metabolic rate and reduced heat production.

Correct Answer is A

Explanation

Choice a reason:
Resonance is the expected percussion note when percussing over normal, healthy lung tissue. This sound is produced due to the presence of air in the lung parenchyma, which allows for the transmission of sound waves through the air-filled spaces. In a healthy individual, the resonance indicates that the lungs are free from any significant abnormalities that could alter the sound, such as fluid or solid masses.
Choice b reason:
Tympanic notes are typically heard over hollow, air-containing structures like the stomach. This sound is not expected in lung percussion unless there is a large, air-filled cavity within the lung tissue, which would be abnormal and indicative of a pathological condition such as a pneumothorax.
Choice c reason:
A flat percussion note is usually heard over dense tissues where air is not present, such as over the thigh muscles or areas of the chest where lung tissue has been replaced by something more solid, like in the case of a pleural effusion or a lung mass.
Choice d reason:
Dullness on percussion usually indicates that the lung is not air-filled and may be suggestive of underlying conditions such as pneumonia, tumor, or atelectasis. It is a higher-pitched sound compared to flatness and is typically found in areas of the lung that are filled with fluid or solid tissue rather than air.

A. Assist the client to a sitting position. B. Percuss the region before auscultating. C. Reduce all environmental noise. D. Palpate the region before auscultating.

Correct Answer is C

Explanation

Choice a reason:
Assisting the client to a sitting position is not the best action to ensure that bowel sounds can be heard. For abdominal auscultation, the patient should be lying down in a supine position to relax the abdominal muscles, which facilitates the hearing of bowel sounds.

Choice b reason:
Percussion of the abdomen before auscultation is not recommended as the best initial action. Percussion can stimulate bowel motility, which may alter the natural bowel sounds that the nurse is attempting to assess.

Choice c reason:
Reducing all environmental noise is the best action to ensure that bowel sounds can be heard clearly. Environmental noise can mask the subtle sounds of bowel motility, and minimizing distractions allows for a more accurate assessment of bowel activity.

Choice d reason:
Palpating the region before auscultating is not the best action because palpation can also stimulate bowel motility and potentially alter the bowel sounds. Auscultation should be performed before palpation during the abdominal examination to avoid this issue.
