1. Why are LDLs known as the 'bad' type of cholesterol?

A. LDL (Low-Density Lipoprotein) is considered 'bad' cholesterol because it deposits cholesterol on the walls of arteries, leading to plaque formation and narrowing of the arteries (atherosclerosis).
B. Both the statement and the reason are correct but are not related
C. The statement is correct, but the reason is not correct
D. The statement is not correct, but the reason is correct

Correct answer: A

Rationale: LDL (Low-Density Lipoprotein) is known as the 'bad' type of cholesterol because it deposits cholesterol on the walls of arteries, leading to plaque formation and narrowing of the arteries (atherosclerosis). This narrowing can restrict blood flow and increase the risk of serious cardiovascular conditions. The statement and the reason are directly related because the adherence of LDL to arterial walls and the subsequent narrowing of the lumen are the primary reasons why it is considered detrimental to heart health. Choice B is incorrect because the statement and reason are related. Choice C is incorrect because both the statement and the reason are correct. Choice D is incorrect because the statement correctly identifies LDL as the 'bad' type of cholesterol due to its actions in the arteries.

2. Mrs. Pichay who is for thoracentesis is assigned by the nurse to any of the following positions, EXCEPT:

A. straddling a chair with arms and head resting on the back of the chair
B. lying on the unaffected side with the bed elevated 30-40 degrees
C. lying prone with the head of the bed lowered 15-30 degrees
D. sitting on the edge of the bed with her feet supported and arms and head on a padded overhead table

Correct answer: D

Rationale: Understanding the underlying pathology and therapeutic techniques ensures that nursing care is not only reactive but also preventative, reducing the risk of complications.

3. Each statement is true of water-soluble vitamins, except one. Which is it?

A. Act as coenzymes
B. Deficiencies develop rapidly
C. Daily intake is necessary
D. Absorbed in the jejunum

Correct answer: B

Rationale: The correct answer is B. Water-soluble vitamins do not develop deficiencies rapidly because the body does not store them for long periods. They must be obtained through food constantly. Choice A is correct because water-soluble vitamins often act as coenzymes in various metabolic reactions. Choice C is correct as daily intake of water-soluble vitamins is necessary since they are not stored in the body. Choice D is incorrect as water-soluble vitamins are absorbed primarily in the small intestine, particularly in the duodenum and ileum, not the jejunum.

4. You are on duty in the medical ward. The mother of your patient who is also a nurse, came running to the nurses station and informed you that Fiolo went into cardiopulmonary arrest.

A. Start basic life support measures
B. Call for the Code
C. Bring the crash cart to the room
D. Go to see Fiolo and assess for airway patency and breathing problems

Correct answer: C

Rationale: Effective nursing care involves comprehensive assessments that address all aspects of a patient's condition, ensuring that interventions are appropriately targeted and outcomes are optimized.

5. What is a likely effect on a patient whose lab results reveal hypoalbuminemia?

A. Infection
B. Rickets
C. Hypertension
D. Edema

Correct answer: D

Rationale: Hypoalbuminemia, which refers to low albumin levels in the blood, is often associated with edema. Albumin helps maintain oncotic pressure, which keeps fluid within blood vessels. When albumin levels are low, this pressure decreases, leading to fluid leakage from the blood vessels into the surrounding tissues, resulting in edema. The other choices are less likely effects of hypoalbuminemia. Hypoalbuminemia doesn't directly cause infections (Choice A), rickets (Choice B) caused by vitamin D deficiency, or hypertension (Choice C) associated with factors like high sodium intake, obesity, and genetic predisposition.
