The nurse read the patient's health history cranial nerve III oculomotor paralysis. Which of the following would the nurse expect?

Муоріа

Normal eye movement

Ptosis will be evident and no pupillary constriction.

The eye cannot look to the outside side.

Answer and Explanation

The Correct Answer is C

(a) Mydriasis:

While mydriasis (dilated pupil) can be associated with cranial nerve III damage, it does not fully describe the range of symptoms expected with oculomotor paralysis. Cranial nerve III controls more functions than pupil dilation, such as eyelid elevation and certain eye movements.

(b) Normal eye movement:

Cranial nerve III paralysis would result in abnormal eye movement due to the loss of control over muscles responsible for moving the eye. Expecting normal eye movement would be incorrect since the paralysis affects the eye's ability to move properly.

Cranial nerve III (oculomotor nerve) paralysis leads to ptosis (drooping eyelid) because it innervates the levator palpebrae superioris muscle. It also affects the pupillary constrictor muscles, resulting in a dilated pupil (lack of pupillary constriction), making this the most comprehensive and accurate answer.

(d) The eye cannot look to the outside side:

Inability to look to the outside (lateral movement) is typically associated with cranial nerve VI (abducens nerve) paralysis, which controls the lateral rectus muscle. Cranial nerve III primarily affects vertical and medial movements, so this is not the expected finding.

Correct Answer is A

Explanation

A) Facial edema: Myxedema is a severe form of hypothyroidism that is often characterized by the accumulation of mucopolysaccharides in the skin and other tissues, leading to facial and peripheral edema. This is a classic symptom of myxedema and is expected in clients with this condition.

B) Diarrhea: Diarrhea is more commonly associated with hyperthyroidism rather than hypothyroidism. Clients with myxedema typically experience constipation due to slowed gastrointestinal motility.

C) Tachycardia: Tachycardia is associated with hyperthyroidism. In contrast, myxedema is associated with bradycardia or a slow heart rate because of the overall slowing of the body's metabolic processes.

D) Heat intolerance: Heat intolerance is a symptom of hyperthyroidism. Clients with myxedema usually experience cold intolerance due to decreased metabolic activity and impaired thermoregulation.

A. Mucous Membranes B. Dorsal surface of the hand C. Dorsal surface of the foot D. Pinnae of the ears

Correct Answer is A

Explanation

A. Mucous Membranes:

In clients with dark skin, mucous membranes such as the lips, tongue, and gums are the best sites to assess for cyanosis. These areas have less pigmentation and are more vascular, allowing for a more accurate evaluation of oxygenation and the presence of cyanosis.

B. Dorsal surface of the hand:

The dorsal surface of the hand can be used to assess for cyanosis in lighter-skinned individuals, but it is less reliable in dark-skinned clients due to the higher melanin content, which can obscure the bluish tint indicative of cyanosis.

C. Dorsal surface of the foot:

Similar to the dorsal surface of the hand, the dorsal surface of the foot is not an ideal site for assessing cyanosis in clients with dark skin. The presence of melanin can make it difficult to detect changes in skin color.

D. Pinnae of the ears:

The pinnae of the ears are also not the best sites for assessing cyanosis in dark-skinned clients. These areas can be highly pigmented, which can mask the bluish discoloration associated with cyanosis. The mucous membranes remain the most reliable site for this assessment.
