The nurse is caring for a 64-year-old male client with diabetes who is being treated with a nonselective beta-blocker. What health education should the nurse prioritize with this client?

The benefit to eating frequent small meals during the day

Perform more frequent blood glucose checks due to effects of the drug

The need to weight himself once per week at the same time of the day

The correct method for taking their own apical pulse

Answer and Explanation

The Correct Answer is A

A.   The benefit to eating frequent small meals during the day: Nonselective beta-blockers can mask symptoms of hypoglycemia, making it harder for patients with diabetes to recognize low
blood sugar levels. Eating frequent small meals can help stabilize blood sugar levels and reduce the risk of hypoglycemia.
B.   Perform more frequent blood glucose checks due to effects of the drug: While it's important for patients with diabetes to monitor their blood glucose levels regularly, this instruction doesn't directly address the potential masking of hypoglycemia symptoms by beta-blockers.
C.   The need to weight himself once per week at the same time of the day: Weight monitoring is important for overall health management but is not specifically related to the use of nonselective beta-blockers in diabetes management.
D.   The correct method for taking their own apical pulse: Knowing how to take one's own apical pulse is important for some individuals, but it's not directly related to the management of
diabetes with nonselective beta-blockers.

Correct Answer is A

Explanation

A. Carbidopa prevents the breakdown of levodopa in the periphery, specifically in the gastrointestinal tract and peripheral tissues, allowing more levodopa to reach the brain and be converted to dopamine. This enhances the effectiveness of levodopa therapy in managing the symptoms of Parkinson's disease.
B. Carbidopa is not the biologic precursor of dopamine. It is a peripheral decarboxylase inhibitor that does not cross the blood-brain barrier.
C. Carbidopa does not directly allow for larger doses of levodopa to be given. However, by

inhibiting the peripheral breakdown of levodopa, it enhances the availability of levodopa to the central nervous system, potentially improving therapeutic efficacy.
D. While levodopa-carbidopa combination therapy may have fewer drug-food interactions compared to levodopa alone, the primary reason for combining these medications is to enhance the effectiveness of levodopa by preventing its peripheral breakdown.

A. CT of the brain B. Electroencephalogram C. Brain stem reflexes D. Pupil response

Correct Answer is C

Explanation

A. CT of the brain can proceed regardless of atropine administration, as it does not directly affect the assessment of brain stem reflexes.
B. Electroencephalogram (EEG) can also proceed regardless of atropine administration, as it evaluates brain electrical activity rather than brain stem reflexes.
C. Assessment of brain stem reflexes should be postponed until all atropine is excreted and no

longer exerting its effects. Atropine can mask or alter the pupillary response and other brain stem reflexes, such as gag reflex and cough reflex, which are important indicators of neurological function.
D. Pupil response assessment should be postponed until atropine effects have dissipated, as

atropine can cause pupillary dilation, which may interfere with accurate assessment of pupil size and reactivity
