HESI Fundamentals
1. The healthcare professional retrieves hydromorphone 4mg/mL from the Pyxis MedStation, an automated dispensing system, for a client who is receiving hydromorphone 3 mg IM 6 hours PRN for severe pain. How many mL should the healthcare professional administer to the client? (Enter the numerical value only. If rounding is required, round to the nearest tenth)
- A. 0.8 mL
- B. 0.75 mL
- C. 0.7 mL
- D. 0.9 mL
Correct answer: A
Rationale: To calculate the mL to administer, divide the ordered dose (3 mg) by the concentration (4 mg/mL). 3 mg ÷ 4 mg/mL = 0.75 mL. Rounding to the nearest tenth, the correct dose to administer is 0.8 mL.
2. A 3-year-old with HIV infection is staying with a foster family who is caring for 3 other foster children in their home. When one of the children acquires pertussis, the foster mother calls the clinic and asks the nurse what she should do. Which action should the nurse take first?
- A. Remove the child with HIV from the foster home.
- B. Report the exposure of the child with HIV to the health department.
- C. Place the child with HIV in reverse isolation.
- D. Review the immunization documentation of the child with HIV.
Correct answer: D
Rationale: The priority action for the nurse is to review the immunization documentation of the child with HIV. This step ensures that the child has received the necessary vaccines to protect against pertussis and other preventable diseases. It is essential to verify the immunization status to provide appropriate care and prevent further transmission of infectious diseases within the foster home. Removing the child from the foster home (Choice A) may not be necessary if the child is adequately protected through immunization. Reporting the exposure to the health department (Choice B) is important but not the first action. Placing the child in reverse isolation (Choice C) is not indicated for pertussis exposure.
3. When preparing to examine a client’s skin using a Wood light, what should the nurse do to facilitate this procedure?
- A. Darken the examining room
- B. Administer a local anesthetic
- C. Obtain a signed informed consent
- D. Shave the skin and scrub it with povidone-iodine (Betadine)
Correct answer: A
Rationale: When using a Wood light to examine the skin, the nurse should darken the examining room. This is necessary because the Wood light emits long-wavelength UV light, which is better visualized in a darkened environment. Administering a local anesthetic (Choice B) is not needed for this procedure. Obtaining a signed informed consent (Choice C) is not directly related to using a Wood light for skin examination. Shaving the skin and scrubbing it with povidone-iodine (Betadine) (Choice D) is not required and may not be appropriate for this type of skin examination.
4. A client with emphysema reports shortness of breath. What is the nurse's priority action?
- A. Administer oxygen therapy.
- B. Assess the client’s respiratory rate and effort.
- C. Prepare the client for intubation.
- D. Increase the client's oxygen flow rate.
Correct answer: B
Rationale: Shortness of breath in a client with emphysema may indicate respiratory distress. Assessing the client’s respiratory rate and effort is the first priority to determine the severity of the distress and guide appropriate interventions. Administering oxygen therapy (Choice A) could be necessary, but assessing the client first is crucial to tailor the intervention. Intubation (Choice C) is an invasive procedure that is not the initial priority. Increasing oxygen flow rate (Choice D) should only be done after a thorough assessment to avoid potential harm.
5. The healthcare provider is caring for a patient who is receiving an intravenous antibiotic. The patient has a serum drug trough of 1.5 mcg/mL. The normal trough for this drug is 1.7 mcg/mL to 2.2 mcg/mL. What will the healthcare provider expect the patient to experience?
- A. Inadequate drug effects
- B. Increased risk of superinfection
- C. Minimal adverse effects
- D. Slowed onset of action
Correct answer: A
Rationale: A serum drug trough level below the normal range (1.7 mcg/mL to 2.2 mcg/mL) indicates that the medication concentration is insufficient to provide therapeutic effects, leading to inadequate drug effects. A low trough level does not directly correlate with an increased risk of superinfection, minimal adverse effects, or a slowed onset of action, as these are more related to the drug's concentration within the therapeutic range.
