HESI PN Nutrition Practice Exam Questions

Question 1 of 5

Why is randomization important in a scientific experiment?

Correct Answer: B

Rationale: Randomization is crucial in a scientific experiment to eliminate bias in the assignment of subjects to groups. By randomly assigning subjects, it helps ensure that any differences observed in the outcomes are due to the experimental treatment and not to preexisting differences between groups. Choice A is incorrect because randomization does not guarantee representativeness but rather minimizes the impact of confounding variables. Choice C is not entirely accurate; while randomization can contribute to accuracy and validity, its primary purpose is to reduce bias. Choice D is incorrect as the goal of randomization is not to balance the number of subjects but to prevent systematic differences between groups.

Question 2 of 5

After surgical repair of a cleft palate, what should be used to prevent injury to the suture line?

Correct Answer: C

Rationale: The correct answer is C: Syringe. Using a syringe helps in feeding without causing injury to the suture line after cleft palate repair because it avoids direct contact with the suture area. Straws and spoons can potentially put pressure on the suture line, leading to injury. Cups may not provide the necessary control to prevent contact with the suture line, unlike a syringe.

Question 3 of 5

How many minerals are known to be essential for human nutrition?

Correct Answer: C

Rationale: There are 16 essential minerals required for human nutrition. These minerals include calcium, potassium, iron, and others. Choice A (8) is incorrect as it underestimates the number of essential minerals. Choice B (12) is also incorrect as it does not encompass the full count of essential minerals. Choice D (20) is incorrect as it overestimates the number of essential minerals.

Question 4 of 5

What is a common symptom of congenital heart disease in infants?

Correct Answer: B

Rationale: Difficulty breathing is a common symptom of congenital heart disease in infants. Infants with congenital heart disease may experience difficulty breathing due to impaired cardiac function, which affects the heart's ability to pump blood effectively. This symptom is often due to issues like heart failure or fluid accumulation in the lungs. Excessive weight gain (Choice A) is not typically associated with congenital heart disease in infants. High blood pressure (Choice C) is less common in infants with congenital heart disease compared to adults. Increased appetite (Choice D) is not a typical symptom of congenital heart disease in infants.

Question 5 of 5

What is one characteristic that differentiates vitamins from minerals?

Correct Answer: A

Rationale: The correct answer is A. Vitamins are organic compounds, containing carbon, which is a key characteristic that differentiates them from minerals. Choice B is incorrect because vitamins do not provide energy; they are not a source of calories. Choice C is incorrect as both vitamins and minerals are considered micronutrients due to being essential in small amounts. Choice D is incorrect because while it is true that vitamins are needed in small amounts, this is not the characteristic that sets them apart from minerals.
