Hi, can you help me with the following multiple choice questions: Thanks!! Z. is a 27-year-old man with readily apparent thyroid goiter. He comments that he gained 5 pounds in the last year, and you notice that his weight is approximately 20 pounds greater than normal. What can you conclude about this patient’s thyroid function? the goiter indicates that he is hyperthyroid the combination of excessive weight and goiter indicates that he is hypothyroid the combination of excessive weight and goiter indicates that he is hyperthyroid he is probably euthyroid, because the weight gain eliminates the possibility of hyperthyroidism it is not possible to make a conclusion from this information provided. For an answer to be correct, both the symptom and the explanation must be correct. Which answer is incorrect? the resting heart rate increases because circulating levels of catecholamines increase. Excess thyroid hormones stimulate the release of more adrenal catecholamines. myocardial contractility increases because thyroid hormones act directly on the heart and act indirectly by potentiating the effect of catecholamines on the myocardium. peripheral resistance decreases because of cutaneous vasodilation as a thermoregulatory response. the circulating half-lives of most exogenously administered drugs decrease because the rate of metabolism increases and drug inactivation is more rapid.

Hi, can you help me with the following multiple choice questions: Thanks!!

Z. is a 27-year-old man with readily apparent thyroid goiter. He comments that he gained 5 pounds in the last year, and you notice that his weight is approximately 20 pounds greater than normal. What can you conclude about this patient’s thyroid function?
1. the goiter indicates that he is hyperthyroid
2. the combination of excessive weight and goiter indicates that he is hypothyroid
3. the combination of excessive weight and goiter indicates that he is hyperthyroid
4. he is probably euthyroid, because the weight gain eliminates the possibility of hyperthyroidism
5. it is not possible to make a conclusion from this information provided.
For an answer to be correct, both the symptom and the explanation must be correct. Which answer is incorrect?
1. the resting heart rate increases because circulating levels of catecholamines increase. Excess thyroid hormones stimulate the release of more adrenal catecholamines.
2. myocardial contractility increases because thyroid hormones act directly on the heart and act indirectly by potentiating the effect of catecholamines on the myocardium.
3. peripheral resistance decreases because of cutaneous vasodilation as a thermoregulatory response.
4. the circulating half-lives of most exogenously administered drugs decrease because the rate of metabolism increases and drug inactivation is more rapid.
