The nurse is caring for a patient who presents to the emergency department with right-sided weakness and dysphasia. Which type of stroke would the nurse suspect?
Transient ischemic attack
Basilar artery syndrome
Left middle cerebral artery syndrome
Right middle cerebral artery syndrome
The Correct Answer is C
A. Transient ischemic attack (TIA): A TIA might cause transient symptoms similar to a stroke, including weakness and dysphasia, but it would not explain why the symptoms are localized to the right side of the body. Additionally, TIA symptoms typically resolve within 24 hours.
B. Basilar artery syndrome: This type of stroke affects the brain stem, resulting in symptoms such as double vision, vertigo, and ataxia, rather than localized right-sided weakness and dysphasia.
C. Left middle cerebral artery syndrome: The left middle cerebral artery (MCA) supplies blood to the left hemisphere of the brain, including areas that control language and motor function on the right side of the body. Thus, an infarct in this area often leads to right-sided weakness and dysphasia, making it the most likely suspect.
D. Right middle cerebral artery syndrome: This would typically result in left-sided weakness and possibly neglect, but not right-sided symptoms

Correct Answer is B
Explanation
A. It increases formation of purines: This is incorrect. Allopurinol works by inhibiting the enzyme xanthine oxidase, which is involved in the conversion of purines to uric acid. Therefore, it reduces, rather than increases, uric acid formation.
B. It blocks formation of uric acid: This is correct. Allopurinol decreases uric acid production by inhibiting the enzyme xanthine oxidase, which converts xanthine to uric acid, thus helping to prevent gout attacks and manage chronic gout.
C. It increases metabolism of purines: Allopurinol does not increase the metabolism of purines. Instead, it reduces the conversion of purines to uric acid, which is the substance that accumulates and causes gout.
D. It excretes proteins: Allopurinol does not facilitate the excretion of proteins. Its primary action is to reduce the production of uric acid.
Correct Answer is D
Explanation
A. Report a headache immediately: Headaches are not a common side effect of propranolol and may not require immediate reporting unless they are severe or unusual in nature.
B. Heart palpitations are common: Beta blockers like propranolol generally help to control heart palpitations and irregular heartbeats rather than cause them.
C. Monitor for bleeding gums: This is not a typical side effect of propranolol. Bleeding gums might be more related to dental issues or other medications.
D. Rise slowly to prevent dizziness: Propranolol can cause orthostatic hypotension, which is a drop in blood pressure upon standing up. Patients should be advised to rise slowly to prevent dizziness or fainting, which is a common side effect of beta blockers.
