Low-density lipoproteins (LDLs) are the so-called "bad" lipoproteins. Which statement best reflects why high levels of LDL are considered unhealthy?

A.

There is an increased risk of hyperthyroidism.

B.

There is an increased risk of heart disease.

C.

There is the possibility of digestive problems.

D.

There is an increased risk of rhabdomyolysis.

Answer and Explanation

The Correct Answer is B

A) There is an increased risk of hyperthyroidism:
High levels of LDL cholesterol are not associated with hyperthyroidism. Hyperthyroidism is a condition related to an overactive thyroid gland, which affects metabolism and hormone levels but does not directly impact LDL cholesterol levels.

 

B) There is an increased risk of heart disease:
LDL cholesterol, often referred to as "bad cholesterol," contributes to the buildup of fatty plaques in the walls of arteries, a process known as atherosclerosis. This buildup can narrow and harden the arteries, leading to reduced blood flow and increasing the risk of heart disease, including conditions such as coronary artery disease, heart attack, and stroke. High LDL levels are considered one of the most significant modifiable risk factors for cardiovascular disease.

C) There is the possibility of digestive problems:
While very high cholesterol levels can sometimes contribute to the formation of gallstones, high LDL cholesterol levels are not directly linked to digestive problems. The primary concern with high LDL is its contribution to cardiovascular disease rather than digestive health.

 

D) There is an increased risk of rhabdomyolysis:
Rhabdomyolysis is a condition caused by the breakdown of muscle tissue, which can lead to the release of muscle proteins into the bloodstream. While certain medications used to lower cholesterol, such as statins, can cause muscle pain and, in rare cases, lead to rhabdomyolysis, high LDL itself is not a direct cause of rhabdomyolysis. The main health concern with high LDL is its contribution to heart disease.

Correct Answer is B

Explanation

Given:

Volume of fluid: 100 mL

Infusion time: 4 hours

Drop factor: 60 gtt/mL

Formula:

Flow rate (gtt/min) = (Volume (mL) / Time (hr)) x Drop factor (gtt/mL) / 60 min/hr

Step 1: Calculate the infusion rate in mL/hr:

Infusion rate (mL/hr) = Volume (mL) / Time (hr)

Infusion rate (mL/hr) = 100 mL / 4 hr

Infusion rate (mL/hr) = 25 mL/hr

Step 2: Calculate the flow rate in gtt/min:

Flow rate (gtt/min) = (Infusion rate (mL/hr) x Drop factor (gtt/mL)) / 60 min/hr

Flow rate (gtt/min) = (25 mL/hr x 60 gtt/mL) / 60 min/hr

Flow rate (gtt/min) = 1500 gtt/hr / 60 min/hr

Flow rate (gtt/min) = 25 gtt/min

Correct Answer is A

Explanation

Convert the dosage to mcg per hour:

15mcg/min×60min/hr=900mcg/hr15

Convert the available nitroglycerin concentration to mcg/mL:

25mg=25,000mcg

Theconcentrationis(25,000mcg/250mL)=100mcg

Calculate the flow rate in mL per hour using the dosage and concentration:

Flowrate(mL/hr)=(900mcg/hr100mcg/mL)=9mL/hr
