HESI LPN
HESI Practice Test for Fundamentals
1. A client has a new prescription for a metered-dose inhaler. Which of the following instructions should the nurse include?
- A. Inhale quickly and deeply while pressing down on the inhaler.
- B. Hold your breath for 10 seconds after inhaling the medication.
- C. Exhale immediately after inhaling the medication.
- D. Shake the inhaler before each use.
Correct answer: B
Rationale: The correct instruction for using a metered-dose inhaler is to hold your breath for 10 seconds after inhaling the medication. This allows the medication to be absorbed more effectively in the lungs. Inhaling quickly and deeply while pressing down on the inhaler (Choice A) may cause the medication to deposit in the mouth and throat rather than reaching the lungs. Exhaling immediately after inhaling the medication (Choice C) may also lead to medication wastage. Shaking the inhaler before each use (Choice D) is not necessary for all types of inhalers and can sometimes cause improper drug delivery.
2. A nurse questions a medication prescription as too extreme in light of the client’s advanced age and unstable status. The nurse understands that this action is an example of which of the following ethical principles?
- A. Fidelity
- B. Autonomy
- C. Justice
- D. Nonmaleficence
Correct answer: D
Rationale: The correct answer is D, Nonmaleficence. Nonmaleficence refers to the principle of 'do no harm.' In this scenario, questioning a potentially harmful prescription for a client with advanced age and unstable status aligns with the principle of nonmaleficence, as the nurse is advocating for the client's safety and well-being. Choice A, Fidelity, refers to being faithful and keeping promises, which is not directly related to the situation described. Choice B, Autonomy, pertains to respecting a patient's right to make their own decisions, which is not the focus of the nurse questioning the prescription. Choice C, Justice, involves fairness and equal treatment, which is not the primary ethical principle at play in this situation.
3. The healthcare provider prescribes morphine sulfate 4mg IM STAT. Morphine comes in 8 mg per ml. How many ml should the LPN/LVN administer?
- A. 0.5 ml
- B. 1 ml
- C. 1.5 ml
- D. 2 ml
Correct answer: A
Rationale: To administer 4 mg of morphine, as prescribed, the LPN/LVN needs to calculate the correct volume based on the concentration provided (8 mg per ml). Since the desired dose is 4 mg, half of 8 mg (0.5 ml) is required to administer the correct amount. Therefore, the correct answer is 0.5 ml. Choices B, C, and D are incorrect as they would either underdose or overdose the patient.
4. The LPN/LVN is caring for a client with chronic obstructive pulmonary disease (COPD) who is receiving oxygen therapy. Which observation indicates that the client is experiencing oxygen toxicity?
- A. Nasal congestion
- B. Cough
- C. Sore throat
- D. Fatigue
Correct answer: C
Rationale: The correct answer is 'C: Sore throat.' Oxygen toxicity can manifest with symptoms like a sore throat, cough, chest pain, difficulty breathing, and fatigue. However, a sore throat can be an early indicator of oxygen toxicity and should prompt immediate attention. Nasal congestion, cough, and fatigue are not specific indicators of oxygen toxicity but could be related to other factors in a client with COPD receiving oxygen therapy.
5. The patient is being treated for cancer with weekly radiation therapy to the head and intravenous chemotherapy treatments. Which assessment is the priority?
- A. Feet
- B. Nail beds
- C. Perineum
- D. Oral cavity
Correct answer: D
Rationale: The correct answer is the oral cavity. During cancer treatment involving radiation to the head and intravenous chemotherapy, the oral cavity is a priority assessment area. Radiation can reduce salivary flow and lower the pH of saliva, which can lead to stomatitis and tooth decay. Assessing the oral cavity allows for the early identification and management of potential complications. Choice A, assessing the feet, is not the priority in this scenario as it is not directly impacted by the described cancer treatments. Choice B, assessing the nail beds, is not the priority compared to the oral cavity. Nail bed assessment may be relevant for certain conditions, but in this case, the oral cavity is of higher priority due to the specific treatment effects. Choice C, assessing the perineum, is also not the priority in this situation as it is not directly affected by the described cancer treatments, unlike the oral cavity.
