Question 1:
The body, at all times, attempts to maintain homeostasis. The best definition of homeostasis is:
A) a process that maintains the stability of the human body’s internal environment in response to changes in internal and external conditions
B) a function via which the body breaks down glucose to use as energy
C) a process that maintains the immune system’s defenses
D) a process in which the body resists change to genetic structure
Answer:
A) a process that maintains the stability of the human body’s internal environment in response to changes in internal and external conditions
Explanation:
Homeostasis refers to the body’s ability to maintain a stable internal environment, which is crucial for normal functioning. This process regulates temperature, pH, and other factors to keep everything balanced.
Question 2:
A warehouse worker ships 25 boxes each day. Every box contains 3 shipping labels. Inventory has 500 shipping labels. How many days will it take to use the inventory of shipping labels? Round to the nearest whole.
A. 7 days
B. 8 days
C. 20 days
D. 6 days
Answer: B) 8 days
Explanation: Each day, the worker ships 25 boxes, each containing 3 labels. So, the worker uses 25 x 3 = 75 labels per day. To find how many days it will take to use the 500 labels, divide the total labels by the daily usage:
500 ÷ 75 = 6.67.
Rounding to the nearest whole number, it will take approximately 8 days to use the inventory.
Question 3:
The largest organ in the body is the ________.
A) skin
B) GI tract
C) femur
D) stomach
Answer:
A) skin
Explanation:
The skin is the largest organ in the body, and it plays an essential role in protecting the body, regulating temperature, and providing sensory input.
Question 4:
What is Erythropoiesis?
A) red blood cell formation
B) white blood cell formation
C) the destruction of red blood cells
D) the destruction of white blood cells
Answer:
A) red blood cell formation
Explanation:
Erythropoiesis is the process by which new red blood cells are produced in the bone marrow. This process is essential for maintaining adequate oxygen levels in the body.
Question 5:
What is the relationship between sarcomeres and muscle cells?
A) sarcomeres are muscle cells
B) sarcomeres contain muscle cells
C) muscle cells contain myofibrils, which in turn are made up of sarcomeres
D) muscle cells contain sarcomeres, which in turn are made up of myofibrils
Answer:
C) muscle cells contain myofibrils, which in turn are made up of sarcomeres
Explanation:
Sarcomeres are the basic functional units of muscle contraction, and they are found within myofibrils. Myofibrils, in turn, are the structural components of muscle cells.
Question 6:
A vitamin’s expiration date has passed. It was supposed to contain 500 mg of Calcium, but it has lost 325 mg of Calcium. How many mg of Calcium is left?
A. 175 mg
B. 135 mg
C. 185 mg
D. 200 mg
Answer:
A) 175 mg
Explanation:
To find out how much Calcium is left, subtract the amount lost from the original amount:
500 mg – 325 mg = 175 mg.
So, 175 mg of Calcium is left in the vitamin.
Question 7:
Cyclic adenosine monophosphate is a substance that performs which of the following?
A) acts as part of the cell membrane
B) acts as energy for the cell
C) acts as a secondary messenger
D) acts as a hormone
Answer:
C) acts as a secondary messenger
Explanation:
Cyclic adenosine monophosphate (cAMP) acts as a secondary messenger in the cell, helping to relay signals from hormones and other molecules to trigger responses within the cell.
Question 8:
The neuron is composed of a(n) ________, which transmits signals toward the cell body, and a(n) ________, which transmits signals away from the cell body.
Answer:
Dendrite; Axon
Explanation:
The dendrite receives signals from other cells and transmits them toward the cell body, while the axon transmits signals away from the cell body to other neurons or muscles.
Question 9:
Moving the arm toward the body would be described as a ________ movement, rather than a _________ movement.
A) adduction; abduction
B) abduction; adduction
C) flexion; extension
D) extension; flexion
Answer:
A) adduction; abduction
Explanation:
Adduction refers to moving a limb toward the body’s midline, while abduction refers to moving it away from the body.
Question 10:
Which of the following describes the function of the mitochondria in a cell?
A) Protein synthesis
B) Energy production
C) DNA replication
D) Waste removal
Answer:
B) Energy production
Explanation:
Mitochondria are the powerhouse of the cell, responsible for generating energy in the form of ATP, which fuels cellular functions.

HESI A2 Practice Tests: Sample Questions & Answers
Sample Question 1
You have orders to give a patient 20 mg of a certain medication. The medication is stored 4 mg per 5-mL dose. How many milliliters will need to be given?
A. 30 mL
B. 25 mL
C. 20 mL
D. 15 mL
Answer:
B) 25 mL
Explanation:
The medication is stored at 4 mg per 5 mL dose. To calculate how many milliliters are needed for a 20 mg dose, first divide the prescribed amount (20 mg) by the amount in each dose (4 mg).
20 mg ÷ 4 mg = 5 doses.
Now, since each dose is 5 mL, multiply the number of doses (5) by 5 mL:
5 doses x 5 mL = 25 mL.
So, the correct answer is B) 25 mL.
Sample Question 2
A patient is prescribed lorazepam (Ativan) for anxiety. What is the primary therapeutic effect of lorazepam?
A) Reduce blood pressure
B) Increase dopamine levels
C) Provide sedation and reduce anxiety
D) Stimulate the central nervous system
Answer:
C) Provide sedation and reduce anxiety
Explanation:
Lorazepam is a benzodiazepine that works by providing sedation and reducing anxiety. It enhances the effect of a neurotransmitter called gamma-aminobutyric acid (GABA) in the brain, which has a calming effect.
Sample Question 3
A nurse is administering insulin to a diabetic patient. What is the most appropriate action to take before administering the insulin injection?
A) Shake the insulin vial vigorously
B) Check the expiration date on the vial
C) Store the insulin at room temperature for 2 hours
D) Perform a blood sugar test immediately before giving the injection
Answer:
B) Check the expiration date on the vial
Explanation:
Before administering insulin, the nurse should always check the expiration date to ensure the medication is still effective. Shaking insulin can cause air bubbles, and a blood sugar test should be done prior to administration, but the expiration date is a critical first step.
Sample Question 4
Jenny lost 3.2 lb each month for 6 months. How much weight has Jenny lost?
Answer:
19.2 lb
Explanation:
To find the total weight Jenny has lost, multiply the weight lost per month (3.2 lb) by the number of months (6):
3.2 lb x 6 = 19.2 lb.
So, Jenny has lost 19.2 lb.
Sample Question 5
A patient is prescribed amlodipine for hypertension. Which of the following is the most common side effect of this medication?
A) Dizziness
B) Hypoglycemia
C) Tachycardia
D) Diarrhea
Answer:
A) Dizziness
Explanation:
Amlodipine is a calcium channel blocker used to treat high blood pressure. The most common side effect is dizziness due to the blood pressure-lowering effect of the medication. Patients should be advised to rise slowly from a sitting position to avoid dizziness.
Sample Question 6
Fried’s rule for computing an infant’s dose of medication is:
infant’s dose = (Child’s age in months x adult dose) / 150
If the adult dose of medication is 15 mg, how much should be given to a 2-year-old child?
A. 2.4
B. 3.6
C. 48
D. 1.2
Answer:
A) 2.4
Explanation:
First, convert the child’s age to months:
2 years x 12 months = 24 months.
Now, apply Fried’s rule:
infant’s dose = (24 months x 15 mg) / 150
infant’s dose = 360 / 150
infant’s dose = 2.4 mg
So, the correct answer is A) 2.4 mg.
Sample Question 7
A nurse is teaching a patient about taking warfarin (Coumadin). Which of the following statements indicates the need for further teaching?
A) “I will avoid eating foods rich in vitamin K.”
B) “I will monitor my INR levels regularly.”
C) “I can take aspirin if I develop a headache.”
D) “I will wear a medic-alert bracelet.”
Answer:
C) “I can take aspirin if I develop a headache.”
Explanation:
Patients on warfarin should avoid aspirin because it can increase the risk of bleeding. Warfarin works by inhibiting the clotting process, and combining it with aspirin can exacerbate this effect. The other statements reflect correct patient education for warfarin therapy.
