HESI Fundamentals Practice Questions
1. When reviewing EBP about the administration of O2 therapy, what is the recommended maximum flow rate for regulating O2 via nasal cannula?
- A. Regulate O2 via nasal cannula no more than 6L
- B. Regulate O2 via nasal cannula no more than 2L
- C. Regulate O2 via nasal cannula no more than 4L
- D. Regulate O2 via nasal cannula no more than 8L
Correct answer: A
Rationale: The correct answer is to regulate O2 via nasal cannula no more than 6L. This flow rate is generally recommended to ensure adequate oxygen delivery without causing discomfort or potential harm to the patient. Choices B, C, and D are incorrect as they suggest flow rates that are either too low (2L, 4L) or too high (8L). A flow rate of 2L might not provide sufficient oxygen, while 4L could be inadequate for some patients. On the other hand, a flow rate of 8L could be excessive and potentially harmful, leading to complications like oxygen toxicity. Therefore, the optimal recommendation is to regulate O2 via nasal cannula at a maximum of 6L to balance effectiveness and safety.
2. When assessing a patient's feet, the nurse notices that the toenails are thick and separated from the nail bed. What does the nurse most likely suspect is the cause of this condition?
- A. Fungi
- B. Friction
- C. Nail polish
- D. Nail polish remover
Correct answer: A
Rationale: The nurse would most likely suspect fungi as the cause of thickened and separated toenails. Fungal infections can lead to changes in the nail structure, causing them to thicken and separate from the nail bed. Friction, nail polish, and nail polish remover are less likely to cause these specific nail changes. Friction typically leads to calluses or blisters, while nail polish and nail polish remover do not commonly result in thickened and separated toenails.
3. A nurse in a provider's office is assessing a client who has heart failure. The client has gained weight since her last visit, and her ankles are edematous. Which of the following findings by the nurse is another clinical manifestation of fluid volume excess?
- A. Bounding pulse
- B. Decreased blood pressure
- C. Dry mucous membranes
- D. Weak pulse
Correct answer: A
Rationale: A bounding pulse is indicative of fluid volume excess. In this case, the client's weight gain and edematous ankles already suggest fluid volume overload. A bounding pulse occurs due to increased blood volume and pressure. Choices B, C, and D are not indicative of fluid volume excess. Decreased blood pressure, dry mucous membranes, and weak pulse are more commonly associated with conditions such as dehydration or hypovolemia, where there is a decrease in fluid volume rather than an excess.
4. A client has C-diff infection. Which of the following actions should the nurse take?
- A. Give the client chlorhexidine gluconate for hand hygiene.
- B. Remove the protective gown first when exiting the client's room.
- C. Use alcohol-based hand rub when caring for the client.
- D. Initiate contact precautions when providing client care.
Correct answer: D
Rationale: The correct answer is to initiate contact precautions when providing client care. C-diff (Clostridium difficile) is highly contagious, and contact precautions are necessary to prevent its spread. Giving the client chlorhexidine gluconate for hand hygiene (Choice A) is not specific to managing C-diff. Removing the protective gown first when exiting the client's room (Choice B) may increase the risk of contaminating oneself and the environment. Using alcohol-based hand rub when caring for the client (Choice C) is not sufficient to prevent the transmission of C-diff, as soap and water are more effective against this particular pathogen.
5. A healthcare professional is preparing to administer 750 mL of 0.9% sodium chloride IV to infuse over 7 hours. The healthcare professional should set the pump to deliver how many mL/hr?
- A. 107 mL/hr
- B. 75 mL/hr
- C. 90 mL/hr
- D. 60 mL/hr
Correct answer: A
Rationale: To calculate the mL/hr rate for the infusion, divide the total volume (750 mL) by the total time (7 hours). 750 mL รท 7 hours = 107 mL/hr. This means that the pump should be set to deliver approximately 107 mL/hr. Choice B (75 mL/hr) is incorrect because it does not reflect the correct calculation. Choice C (90 mL/hr) is incorrect as it does not align with the accurate calculation. Choice D (60 mL/hr) is incorrect as it does not match the correct mL/hr rate obtained through the calculation.
