Nursing Battery Exam Practice Question by M.L and A.R (SFC-CON)

Eugene has been choosing which particular program he will pursue. One thing on his mind is that he is interested in pursuing the science of the chemical basis of life. What program is he likely to pursue in college?

• Analytical Chemistry

• Biochemistry

• Organic Chemistry

• Inorganic Chemistry

Answer explanation

Eugene is interested in the chemical basis of life, which aligns with biochemistry. This field studies the chemical processes within and related to living organisms, making it the most suitable choice for his interests.

Anna poured coconut oil into a water solution. She noticed that the coconut oil stays suspended above the water. What characteristic of the coconut oil is observed?

• Coconut oil is hydrophilic

• Coconut oil has higher polarity than water

• Coconut oil is composed of a hydrophobic head

• Coconut oil is hydrophobic

Answer explanation

Coconut oil is hydrophobic, meaning it does not mix with water. This is why it stays suspended above the water instead of dissolving, indicating its non-polar nature compared to water's polarity.

During cell division, the chromatin turns into what molecule?

• Deoxyribonucleic Acid

• Ribonucleic Acid

• Nucleotides

• Chromosomes

Answer explanation

During cell division, chromatin condenses and organizes into chromosomes, which are the structures that carry genetic information. Therefore, the correct answer is chromosomes.

What enzyme dissolves polysaccharides?

• Salivary amylase

• Peptin

• Pancreatic amylase

• Both A and C

Answer explanation

Both salivary amylase and pancreatic amylase are enzymes that break down polysaccharides into simpler sugars. Therefore, the correct answer is 'Both A and C'.

All but one of the following is not true regarding polysaccharides. Which one is not a polysaccharide?

• Glycogen

• Chitin

• Lactose

• Cellulose

Answer explanation

Lactose is a disaccharide, composed of two monosaccharides (glucose and galactose), while glycogen, chitin, and cellulose are polysaccharides made of long chains of monosaccharides.

Madam Charlene Bulan asked a nursing student about the best way to describe an amino acid. What would you answer if you were in the nursing student's situation?

• Amino acids are the building blocks of proteins.

• Amino acids are components of hemoglobin.

• Amino acids are bonded with hydrogen bonds.

• None of the above

Answer explanation

Amino acids are indeed the building blocks of proteins, which is their primary role in biology. The other options are either too specific or incorrect, making the first choice the best description.

Mark is a nursing student who is tasked with enumerating the elements that build nucleic acids. What should Mark enumerate in front of the class?

• Nucleic acid is made up of carbon, hydrogen, oxygen, nitrogenous base

• Nucleic acid is made up of carbon, hydrogen, oxygen, nitrogenous base, phosphate

• Nucleic acid is made up of carbon, hydrogen, oxygen, nitrogenous base, phosphate, sugar

• Nucleic acid is made up of carbon, hydrogen, oxygen, nitrogenous base, phosphate, sugar, and ribose

Answer explanation

Nucleic acids are composed of nucleotides, which include a nitrogenous base, a sugar (ribose or deoxyribose), and a phosphate group. Therefore, the correct enumeration includes carbon, hydrogen, oxygen, nitrogenous base, phosphate, and sugar.

Among the following, which function is not associated with lipids?

• Energy reserve

• Energy source for muscles

• Component of cell membrane

• None of the Above

Answer explanation

All listed functions are associated with lipids: they serve as energy reserves, provide energy for muscles, and are key components of cell membranes. Therefore, the correct answer is 'None of the Above'.

It is a mechanism that regulates

the pH level of the blood in the human body.

• Negative feedback mechanism

• Positive feedback mechanism

• Bicarbonate buffer system

• None of the Above

Answer explanation

The bicarbonate buffer system is crucial for regulating blood pH by neutralizing excess acids or bases, maintaining homeostasis. Unlike feedback mechanisms, it directly stabilizes pH levels in the body.

What speeds up a chemical reaction?

• Enzyme

• Catalase

• Lipase

• Heat

Answer explanation

Enzymes are biological catalysts that speed up chemical reactions by lowering the activation energy required. Catalase and lipase are specific types of enzymes, while heat can also increase reaction rates but is not a catalyst.
