Sample UATF Enfermería PSA Practice Questions

Try these sample questions to test your UATF Enfermería PSA exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 79+ question experience with AI tutoring.

1Which cellular organelle is responsible for synthesizing ATP through oxidative phosphorylation?
A.Mitochondria
B.Ribosome
C.Golgi apparatus
D.Lysosome
Explanation: Mitochondria are the powerhouses of eukaryotic cells, generating the vast majority of cellular adenosine triphosphate (ATP) via the Krebs cycle and electron transport oxidative phosphorylation.
2What is the primary function of ribosomes in eukaryotic and prokaryotic cells?
A.Protein synthesis
B.Lipid storage
C.DNA replication
D.Cellular waste degradation
Explanation: Ribosomes are ribonucleoprotein complexes that translate genetic instructions from mRNA into polypeptide chains (proteins).
3When a human red blood cell is placed in a hypertonic solution, what physiological phenomenon occurs?
A.Crenation (cell shrinkage due to water exiting by osmosis)
B.Hemolysis (cell swelling and bursting due to water entering)
C.Plasmolysis with cell wall detachment
D.No net movement of water across the membrane
Explanation: In a hypertonic environment (higher solute concentration outside), water moves out of the erythrocyte by osmosis along its concentration gradient, causing the cell to shrink and develop notched edges (crenation).
4Which of the following transport mechanisms across the plasma membrane requires metabolic energy in the form of ATP?
A.Sodium-potassium pump (Na+/K+-ATPase)
B.Simple diffusion of oxygen
C.Facilitated diffusion of glucose through GLUT transporters
D.Osmosis of water molecules
Explanation: The sodium-potassium pump is a primary active transport mechanism that hydrolyzes ATP to move 3 Na+ ions out of the cell and 2 K+ ions into the cell against their respective electrochemical gradients.
5What type of chemical bond links individual amino acids together to form a polypeptide chain?
A.Peptide bond (covalent amide linkage)
B.Glycosidic bond
C.Phosphodiester bond
D.Ester bond
Explanation: Amino acids are joined by covalent peptide bonds formed between the carboxyl group (-COOH) of one amino acid and the amino group (-NH2) of another through a dehydration synthesis reaction.
6Which biomolecule constitutes the primary structural component of the lipid bilayer of biological membranes?
A.Phospholipids
B.Triglycerides
C.Glycogen
D.Collagen
Explanation: Phospholipids are amphipathic molecules with hydrophilic phosphate heads and hydrophobic fatty acid tails that spontaneously form a bilayer in aqueous environments.
7During which phase of mitosis do sister chromatids separate and move toward opposite poles of the cell?
A.Anaphase
B.Prophase
C.Metaphase
D.Telophase
Explanation: In anaphase, the centromeres divide and the sister chromatids (now individual chromosomes) are pulled by mitotic spindle fibers toward opposite centrosome poles.
8What is the net gain of ATP molecules produced per molecule of glucose during anaerobic glycolysis?
A.2 ATP
B.4 ATP
C.32 ATP
D.38 ATP
Explanation: Glycolysis consumes 2 ATP in its preparatory phase and generates 4 ATP in the payoff phase, resulting in a net yield of 2 ATP (and 2 NADH) per glucose molecule under anaerobic conditions.
9Which enzyme is responsible for unwinding the double helix during DNA replication?
A.Helicase
B.DNA Polymerase
C.Ligase
D.Topoisomerase
Explanation: DNA helicase breaks the hydrogen bonds between complementary nitrogenous bases, unwinding the double-stranded DNA molecule at the replication fork.
10Which nitrogenous base is present in RNA but absent in DNA?
A.Uracil
B.Thymine
C.Guanine
D.Cytosine
Explanation: RNA contains uracil (U), which pairs with adenine (A), whereas DNA contains thymine (T) in place of uracil.

About the UATF Enfermería PSA Exam

The Prueba de Suficiencia Académica (PSA) is a current admission route for the Carrera de Enfermería at Universidad Autónoma Tomás Frías (UATF) in Potosí. This independent English-language MCQ study adaptation uses the university's published Enfermería guide, labeled PSA-2018, for Biología, Química, Lenguaje, and Matemáticas. It is not an official translation, a current-format simulation, or a claim that the older guide is a 2026 convocatoria.

Assessment

Career-designed PSA knowledge questionnaire. UATF currently lists PSA as an Enfermería entry route; its published career guide, labeled PSA-2018, covers Biología, Química, Lenguaje, and Matemáticas. A newer 2026 weighting, item type, or section-level threshold was not published in the reviewed materials.

Frequently Asked Questions

What subjects are tested on the UATF Enfermería PSA?

The official UATF nursing syllabus specifies four assessable areas: Biología, Química, Lenguaje, and Matemáticas.

What is the minimum passing score for admission?

A current Enfermería passing threshold was not published in the reviewed UATF DSA, career page, or subject guide. Applicants should use the active career convocatoria rather than assume a university-wide score.

Is this practice bank an official UATF test?

No. It is an independent English-language MCQ study adaptation designed to reinforce the official syllabus topics published by UATF DSA.
