Match the following drug classification with the appropriate drug,

Listeriosis is a foodborne illness that can have severe consequences during pregnancy. To minimize the risk of listeriosis, a pregnant client should avoid certain foods that are more likely to be contaminated with the bacteria Listeria. The correct statement that indicates an understanding of the teaching is:

C) "I can eat grilled chicken on a bun at lunchtime."

Grilled chicken is a safe option, and as long as it's properly cooked, it's a suitable choice during pregnancy. The other options are not recommended during pregnancy:

A) Soft cheeses, like Brie or feta, can carry a risk of Listeria contamination, so they should be avoided.

B) Seafood salad from the grocery store may not be safe as it could contain seafood that's been sitting at improper temperatures, which can increase the risk of foodborne illness.

D) Hot dogs can also be a risk as they are often not served steaming hot, which is necessary to kill any potential Listeria contamination.

Class IV antidysrhythmics or calcium channel blockers decrease the flow of calcium ions into cardiac and vascular smooth muscle cells, thus decreasing heart rate and contractions.By reducing the calcium influx, they also decrease the slope of phase 0 and 4 and prolong phase 2 of the cardiac action potential.This results in vasodilation, reduced myocardial oxygen demand, and decreased conduction through the AV node.

Choice A is wrong because calcium channel blockers do not increase blood vessel spasm, but rather cause vasodilation.

Choice C is wrong because calcium channel blockers do not decrease refractory period, but rather prolong it by extending phase 2 of the cardiac action potential.

Choice D is wrong because calcium channel blockers do not increase heart rate, but rather decrease it by slowing down the pacemaker activity and AV nodal conduction.

Normal ranges for heart rate are 60 to 100 beats per minute, and for blood pressure are 120/80 mmHg or lower.
