HESI Fundamental Practice Exam
1. A charge nurse is teaching a newly licensed nurse about the care of a client who has methicillin-resistant Staphylococcus aureus (MRSA). Which of the following statements should the charge nurse identify as an indication that the newly licensed nurse understands the teaching?
- A. I should obtain a specimen for culture and sensitivity after the first dose of an antimicrobial.
- B. MRSA is usually resistant to vancomycin, so another antimicrobial will be prescribed.
- C. I will protect others from exposure when I transport the client outside the room.
- D. To decrease resistance, antimicrobial therapy is discontinued when the client is no longer febrile.
Correct answer: C
Rationale: The correct answer is C. Protecting others from exposure when transporting a client with MRSA is crucial in preventing the spread of infection. This statement demonstrates understanding of infection control measures. Stating that MRSA is usually resistant to vancomycin (choice B) is incorrect; vancomycin is often effective against MRSA. Obtaining a specimen for culture and sensitivity after the first dose of an antimicrobial (choice A) is unnecessary and not indicated. Discontinuing antimicrobial therapy when the client is no longer febrile (choice D) is incorrect because antimicrobial therapy should be completed as prescribed to prevent the development of resistant strains.
2. A client with chronic obstructive pulmonary disease (COPD) is prescribed albuterol. The nurse should monitor for which potential side effect?
- A. Tachycardia
- B. Nausea
- C. Dry mouth
- D. Weight gain
Correct answer: A
Rationale: Correct Answer: A. Albuterol, a bronchodilator commonly used in COPD, can cause tachycardia as a potential side effect due to its beta-agonist properties that can stimulate the heart. Nausea (Choice B), dry mouth (Choice C), and weight gain (Choice D) are less likely associated with albuterol use. Nausea and dry mouth are not common side effects of albuterol, and weight gain is not typically linked to its use. Therefore, the nurse should primarily monitor for tachycardia when a client is prescribed albuterol for COPD.
3. A nurse plans to talk to the parents of a toddler about toilet training. What should the nurse explain is the most important factor in the process of toilet training?
- A. Parents' attitude about it
- B. Child's desire to remain dry
- C. Child's ability to sit still on the toilet
- D. Parents' willingness to work at the toilet training
Correct answer: D
Rationale: The most crucial factor in the process of toilet training is the parents' willingness to consistently engage and work with their child. While parents' attitude and the child's desire to remain dry can influence the process, the key to successful toilet training lies in the parents' commitment and effort. The child's ability to sit still on the toilet is important but not as critical as the parents' active involvement and support in guiding and encouraging the child through the training process.
4. Which toy is most appropriate for an 18-month-old child?
- A. A pull toy
- B. A puzzle with large pieces
- C. A book with large pictures
- D. A doll with small clothes
Correct answer: A
Rationale: A pull toy is the most appropriate choice for an 18-month-old child. At this age, children are developing their motor skills and coordination, and a pull toy can help with these aspects by encouraging movement and coordination. Puzzle with large pieces (Choice B) may pose a choking hazard for a child of this age due to small parts. While a book with large pictures (Choice C) can be engaging and beneficial for language development, a pull toy is more suitable for promoting physical development in an 18-month-old. A doll with small clothes (Choice D) is not ideal for this age group as small parts can be a choking hazard.
5. Which vitamin deficiency is most associated with night blindness?
- A. Vitamin A
- B. Vitamin B12
- C. Vitamin C
- D. Vitamin D
Correct answer: A
Rationale: The correct answer is Vitamin A. Vitamin A deficiency leads to night blindness because this vitamin is crucial for the formation of rhodopsin, a photopigment in the retina. Rhodopsin is essential for vision in low-light conditions. Vitamin B12 deficiency can lead to anemia and neurological issues but is not directly related to night blindness. Vitamin C deficiency can cause scurvy, affecting connective tissues, but not night vision. Vitamin D deficiency can lead to bone disorders but is not primarily associated with night blindness.
