Low-density lipoproteins (LDLs) are the so-called "bad" lipoproteins. Which statement best reflects why high levels of LDL are considered unhealthy?
There is an increased risk of hyperthyroidism.
There is an increased risk of heart disease.
There is the possibility of digestive problems.
There is an increased risk of rhabdomyolysis.
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 C
Explanation
Given:
Ordered dose of acetaminophen: 10 mg/kg
Child's weight: 22 lb
Concentration of acetaminophen liquid: 160 mg/5 mL
Step 1: Convert child's weight from pounds to kilograms:
1 pound (lb) = 0.453592 kilograms (kg)
Child's weight in kg = 22 lbs x 0.453592 kg/lb = 9.976824 kg
Step 2: Calculate the total dose of acetaminophen:
Total dose (mg) = Ordered dose (mg/kg) x Child's weight (kg)
Total dose (mg) = 10 mg/kg x 9.976824 kg
Total dose (mg) = 99.76824 mg
Step 3: Calculate the volume to be administered:
Volume (mL) = Total dose (mg) / Concentration (mg/mL)
Volume (mL) = 99.76824 mg / 160 mg/5 mL
Volume (mL) = 99.76824 mg x (5 mL / 160 mg)
Volume (mL) = 3.1177575 mL
Step 4: Round to the nearest tenth:
Volume (mL) ≈ 3.1 mL
