HESI PN Nutrition Practice Exam
1. What is the term for the amount of heat required to raise the temperature of one kilogram of water by one degree Celsius?
- A. Calorie
- B. Joule
- C. Kilojoule
- D. Kilocalorie
Correct answer: D
Rationale: The correct answer is D, Kilocalorie. The term kilocalorie, often referred to as a calorie, is the amount of heat required to raise the temperature of one kilogram of water by one degree Celsius. While Choice A, Calorie, is technically correct, it is not the most specific term for the described amount of heat. Choice B, Joule, is a unit of energy but not specifically related to the amount of heat required to raise the temperature of water. Choice C, Kilojoule, is also a unit of energy but not the precise term for the heat required to raise the temperature of water by one degree Celsius.
2. A client with rheumatoid arthritis is prescribed methotrexate. What is the most important instruction the practical nurse (PN) should provide to the client?
- A. Take the medication on an empty stomach.
- B. Avoid taking folic acid supplements.
- C. Report any signs of infection immediately.
- D. Increase intake of vitamin C-rich foods.
Correct answer: C
Rationale: Correct Answer: The most important instruction for a client taking methotrexate is to report any signs of infection immediately. Methotrexate can suppress the immune system, making the client more susceptible to infections. Early detection and treatment of infections are crucial to prevent complications. Instructing the client to be vigilant for signs of infection empowers them to take prompt action, enhancing their overall safety and well-being.
3. What is a common symptom of congenital heart disease in infants?
- A. Excessive weight gain
- B. Difficulty breathing
- C. High blood pressure
- D. Increased appetite
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.
4. A 25-year-old primigravida at 16 weeks gestation is admitted to the hospital with a diagnosis of hyperemesis gravidarum. Which nursing diagnosis should have the highest priority?
- A. Fluid volume deficit
- B. Altered nutrition: less than body requirements
- C. Anxiety related to new situational crisis
- D. Activity intolerance related to fatigue
Correct answer: A
Rationale: In a case of hyperemesis gravidarum, the priority nursing diagnosis should be addressing the Fluid volume deficit. This condition can lead to serious complications such as electrolyte imbalances and dehydration, which can endanger both the mother and the fetus if not managed promptly. Altered nutrition: less than body requirements is important but addressing the fluid volume deficit takes precedence as it poses an immediate threat. Anxiety related to new situational crisis and Activity intolerance related to fatigue are valid concerns, but they are secondary to the critical issue of fluid volume deficit in this scenario.
5. The nurse is discharging an adult woman who was hospitalized for 6 days for treatment of pneumonia. While the nurse is reviewing the prescribed medications, the client appears anxious. What action is most important for the nurse to implement?
- A. Instruct the client to repeat the medication plan
- B. Encourage the client to take a PRN antianxiety drug
- C. Provide written instructions that are easy to follow
- D. Include a family member in the teaching session
Correct answer: D
Rationale: Including a family member in the teaching session is the most important action for the nurse to implement in this scenario. By involving a family member, the nurse can ensure that there is additional support and reinforcement of the medication plan. This can help the client and family better understand and adhere to the prescribed medications, reducing the client's anxiety. Instructing the client to repeat the medication plan (Choice A) may not address the client's anxiety effectively. Encouraging the client to take a PRN antianxiety drug (Choice B) should not be the first intervention without exploring other supportive measures. Providing written instructions (Choice C) alone may not offer the immediate support and reassurance needed for the anxious client.
