HESI LPN
HESI Practice Test for Fundamentals
1. A nurse is reviewing the correct use of a fire extinguisher with a client. Which of the following actions should the nurse direct the client to take first?
- A. Remove the safety pin from the extinguisher.
- B. Aim the extinguisher at the base of the fire.
- C. Squeeze the handle to release the extinguishing agent.
- D. Sweep the extinguisher from side to side.
Correct answer: A
Rationale: The correct first step in using a fire extinguisher is to remove the safety pin. This action enables the extinguisher to be activated and used effectively. Choice B, aiming the extinguisher at the base of the fire, comes after removing the safety pin. Choice C, squeezing the handle to release the extinguishing agent, and choice D, sweeping the extinguisher from side to side, are subsequent steps in using a fire extinguisher and should follow removing the safety pin.
2. A nurse is preparing to administer enoxaparin subcutaneously. Which of the following actions should the nurse take?
- A. Administer the medication with the needle at a 45-degree angle.
- B. Administer the medication with the needle at a 90-degree angle.
- C. Administer the medication with the needle at a 30-degree angle.
- D. Administer the medication with the needle at a 15-degree angle.
Correct answer: B
Rationale: Enoxaparin should be administered with the needle at a 90-degree angle to ensure proper subcutaneous delivery. Choice B is correct as it aligns with the recommended angle for subcutaneous injections. Administering enoxaparin at a 45-degree angle (Choice A), 30-degree angle (Choice C), or 15-degree angle (Choice D) would not be appropriate and may lead to improper administration or absorption of the medication.
3. The clinician is assessing a client with a Stage 2 skin ulcer. Which of the following treatments is most effective to promote healing?
- A. Covering the wound with a dry dressing
- B. Using hydrogen peroxide soaks
- C. Leaving the area open to dry
- D. Applying a hydrocolloid or foam dressing
Correct answer: D
Rationale: Applying a hydrocolloid or foam dressing is the most effective treatment to promote healing for a Stage 2 skin ulcer. These dressings create a moist environment that supports healing and prevents further tissue damage. Option A (covering the wound with a dry dressing) can lead to drying out the wound bed, hindering healing. Option B (using hydrogen peroxide soaks) can be too harsh and may damage the surrounding healthy tissue. Option C (leaving the area open to dry) can delay healing as it does not provide the necessary moist environment for optimal wound healing.
4. The patient is receiving chemotherapy for breast cancer. Which of the following laboratory values would be most important to monitor?
- A. White blood cell count
- B. Hemoglobin level
- C. Serum creatinine
- D. Blood glucose level
Correct answer: A
Rationale: Monitoring the white blood cell count is crucial when a patient is undergoing chemotherapy for breast cancer. Chemotherapy can lead to neutropenia, a condition of low white blood cell count, which significantly increases the risk of infections. Monitoring white blood cell count helps healthcare providers intervene promptly to prevent severe infections. Hemoglobin level, while important in assessing oxygen-carrying capacity, is not the priority in this scenario. Serum creatinine and blood glucose levels are not directly impacted by chemotherapy for breast cancer.
5. 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.
