What are clinical manifestations of hypothyroidism? (Select all that apply)
Lethargy
Constipation
Restlessness
Intolerance to heat
The Correct Answer is A
Choice A reason: Lethargy is a common manifestation of hypothyroidism, resulting from slowed metabolism due to low thyroid hormone levels. It leads to fatigue and reduced energy, aligning with hypothyroid symptoms, making it a correct choice for clinical manifestations.
Choice B reason: Constipation is a hallmark of hypothyroidism, caused by decreased gastrointestinal motility from low thyroid hormone. This digestive slowing is a frequent complaint, making it a correct selection for hypothyroidism’s clinical manifestations.
Choice C reason: Restlessness is associated with hyperthyroidism, not hypothyroidism, which causes lethargy and slowed activity. Hypothyroid patients lack the agitation seen in hyperthyroid states, so this is incorrect for hypothyroidism manifestations.
Choice D reason: Intolerance to heat is a hyperthyroidism symptom, not hypothyroidism, where patients experience cold intolerance due to slowed metabolism. This is opposite to hypothyroid effects, so it’s incorrect for hypothyroidism’s clinical manifestations.

Correct Answer is C
Explanation
Choice A reason: Insufficient mast cell numbers are not a primary cause of impaired healing in older adults. Mast cells contribute to inflammation, but chronic diseases like diabetes disrupt multiple healing pathways more significantly, making this incorrect.
Choice B reason: Circulatory impairment, such as atherosclerosis, can delay healing by limiting oxygen and nutrient delivery. However, it’s often a consequence of chronic illnesses like diabetes, which broadly affect healing, making this less primary than chronic conditions.
Choice C reason: Underlying chronic illnesses, like diabetes or cardiovascular disease, impair inflammation and wound healing in older adults by disrupting immune function, collagen deposition, and perfusion. These prevalent conditions directly impact healing, making this the correct cause.
Choice D reason: Complement and chemotaxis deficiencies occur in specific immunodeficiencies, not commonly in aging. Chronic illnesses like diabetes more consistently impair healing through systemic effects, making this a less likely primary cause.
Correct Answer is A
Explanation
Choice A reason: Atherosclerosis erodes the vessel wall by forming plaques that weaken arterial layers, promoting aneurysm formation. This degenerative process destabilizes the wall, making it the correct effect in aneurysm development.
Choice B reason: Ischemia of the intima is not a primary atherosclerosis effect; plaques cause wall damage, not just intimal ischemia. Vessel wall erosion is more accurate for aneurysm formation, so this is incorrect.
Choice C reason: Atherosclerosis narrows vessels but doesn’t primarily obstruct them in aneurysm formation. Wall erosion and weakening lead to dilation, not blockage, so this is incorrect for aneurysm development.
Choice D reason: Atherosclerosis reduces nitric oxide, impairing vasodilation, but this isn’t directly linked to aneurysms. Vessel wall erosion by plaques is the key mechanism, so this is incorrect for the effect.
