HESI RN
HESI Nutrition Practice Exam
1. A nurse is reinforcing teaching with a group of older adults about oil-rich foods. The nurse should include which of the following foods as the equivalent of 4 tsp of oil?
- A. 1 tbsp of soft margarine
- B. ½ oz of nuts
- C. 2 tbsp of peanut butter
- D. 1 oz of sunflower seeds
Correct answer: C
Rationale: The correct answer is C: 2 tbsp of peanut butter. Two tablespoons of peanut butter is approximately equivalent to 4 teaspoons of oil, providing healthy fats in the diet. Choice A, 1 tbsp of soft margarine, is not equivalent to 4 tsp of oil as margarine contains additional ingredients. Choice B, ½ oz of nuts, and choice D, 1 oz of sunflower seeds, do not provide an equivalent amount of oil as requested in the question.
2. Which of the following is a common presentation in women with polycystic ovarian syndrome?
- A. Oligomenorrhea, obesity, and hirsutism
- B. Amenorrhea, generalized hair loss, and weight gain
- C. Repeated ectopic pregnancies and chronic pelvic pain
- D. Fatigue, body aches, and menorrhagia
Correct answer: A
Rationale: The correct answer is A: Oligomenorrhea, obesity, and hirsutism. Polycystic ovarian syndrome (PCOS) commonly presents with irregular periods (oligomenorrhea), obesity, and increased hair growth (hirsutism) due to hormonal imbalances. Choice B is incorrect as amenorrhea (absence of periods), generalized hair loss, and weight gain are not typical features of PCOS. Choice C is incorrect as repeated ectopic pregnancies and chronic pelvic pain are not characteristic of PCOS. Choice D is incorrect as fatigue, body aches, and menorrhagia (excessive menstrual bleeding) are not primary symptoms seen in PCOS.
3. Which of the following is a lipid that is a membrane component and a precursor to significant hormones?
- A. Nucleic acids
- B. Proteins
- C. Carbohydrates
- D. Steroids
Correct answer: D
Rationale: The correct answer is D, Steroids. Steroids are a type of lipid that function as essential components of cell membranes and serve as precursors for significant hormones like estrogen and testosterone. Nucleic acids (choice A) are not lipids but are molecules like DNA and RNA that store genetic information. Proteins (choice B) and carbohydrates (choice C) are biomolecules but are not lipids and do not serve as precursors for hormones or membrane components.
4. A healthcare professional is focusing on improving the ability to multitask without losing focus and to turn problems into opportunities. Which of the following leadership theories describes the professional's focus?
- A. Emotional intelligence
- B. Motivation theory
- C. Situational leadership theory
- D. Transformational leadership theory
Correct answer: B
Rationale: Motivation theory explains that individuals act based on what they want to achieve, focusing on goals and desires. In this scenario, the healthcare professional's emphasis on improving multitasking skills and problem-solving aligns with the essence of motivation theory. Emotional intelligence primarily pertains to understanding and managing emotions, not specifically related to multitasking and problem-solving. Situational leadership theory emphasizes adapting leadership styles based on the situation and followers, not directly related to individual focus improvement. Transformational leadership theory focuses on inspiring and motivating followers to achieve common goals rather than individual task management and problem-solving skills.
5. A 2-year-old is admitted to the hospital with possible encephalitis, and a lumbar puncture is scheduled. Which information should the nurse provide this child concerning the procedure?
- A. Describe the side-lying, knees-to-chest position that must be assumed during the procedure.
- B. Explain that fluids cannot be taken for 8 hours before the procedure and for 4 hours after the procedure.
- C. Reassure the child that there will be no restrictions on activity after the procedure is completed.
- D. Tell the child to expect loud clicking noises during the procedure that may be slightly annoying.
Correct answer: A
Rationale: Children, especially young ones, benefit from knowing what position they will be in during a procedure as it helps them understand and feel more in control. Describing the side-lying, knees-to-chest position can reduce anxiety and promote cooperation during the lumbar puncture. Choice B is incorrect because the question is about preparing the child for the procedure, not about pre-procedure fasting requirements. Choice C is incorrect because there may be restrictions on activity after the procedure. Choice D is incorrect because mentioning loud clicking noises may increase the child's anxiety and fear.
