Smoking, Diabetes, Atherosclerosis, and Weak pedal pulses.

Factors that contribute to poor circulation to the limb include:

Smoking: It can cause constriction and damage to the blood vessels, leading to poor circulation.
Diabetes: High blood sugar levels can damage blood vessels and nerves, leading to poor circulation.
Atherosclerosis: This is a condition where plaque builds up in the arteries, narrowing them and reducing blood flow.
Weak pedal pulses: This can be a sign of reduced blood flow to the lower extremities. A sodium-restricted diet (Choice B) is not typically associated with poor circulation.

Correct Answer is B

Explanation

A. The patient has a history of migraine headaches. B. The patient has a history of hypothyroidism. C. The patient has a history of hypertension. D. The patient has a history of bronchial asthma.

Correct Answer is D

Explanation

Choice A rationale

Propranolol is sometimes used to prevent migraines, so a history of migraines would not typically be a contraindication.

Choice B rationale

Hypothyroidism is not typically a contraindication for propranolol. However, propranolol can affect the metabolism of thyroid hormones and may mask signs of hyperthyroidism.

Choice C rationale

Propranolol is often used to treat hypertension, so a history of hypertension would not typically be a contraindication.

Choice D rationale

Propranolol is a non-selective beta-blocker, which means it blocks beta receptors in both the heart and the lungs. This can potentially cause bronchoconstriction and exacerbate asthma symptoms, so it should be used with caution in patients with a history of bronchial asthma.
