HESI Fundamentals 2023 Quizlet
1. A client with diabetes mellitus is being taught by a nurse how to perform a capillary blood glucose test. Which of the following instructions should the nurse include in the teaching?
- A. Don sterile gloves after cleansing the site
- B. Puncture the site after cleansing and before the antiseptic dries
- C. Gently wipe the puncture site until a large droplet of blood forms
- D. Hold the finger below the heart level to puncture
Correct answer: B
Rationale: The correct instruction is to puncture the site after cleansing and before the antiseptic dries. This sequence helps ensure proper blood collection without introducing contaminants. Choice A is incorrect because wearing sterile gloves is not necessary for capillary blood glucose testing. Choice C is incorrect as wiping the puncture site can introduce contaminants and alter the blood sample. Choice D is incorrect as holding the finger below the heart level is not required for a capillary blood glucose test.
2. A family has decided to withhold “extraordinary care” for a newborn with severe abnormalities. How should the nurse interpret this decision?
- A. The newborn has no rights.
- B. It is the same as euthanasia.
- C. It is illegal professional practice.
- D. The newborn is being allowed to die.
Correct answer: D
Rationale: Withholding extraordinary care in cases of severe abnormalities is a legal and ethical decision. It allows the newborn to die naturally without aggressive interventions. Choice A is incorrect because all individuals, including newborns, have rights. Choice B is incorrect because withholding extraordinary care is not equivalent to euthanasia, which involves actively ending a life. Choice C is incorrect because such decisions are legally and ethically permissible when made in consideration of the best interests of the newborn.
3. A client who is 24 weeks pregnant presents with a complaint of feeling dizzy when lying on her back. What is the best response by the nurse?
- A. Advise the client to lie on her side
- B. Encourage the client to drink more fluids
- C. Suggest the client elevate her legs when lying down
- D. Recommend the client take short walks throughout the day
Correct answer: A
Rationale: The correct answer is to advise the client to lie on her side. Lying on the side can prevent the compression of the vena cava, which can cause dizziness in pregnant women. Encouraging the client to drink more fluids (Choice B) may be beneficial for other conditions but is not the best response for dizziness when lying on her back. Suggesting the client elevate her legs when lying down (Choice C) is not directly related to the issue described by the client. Recommending the client take short walks throughout the day (Choice D) may be helpful for other pregnancy-related symptoms but is not the most appropriate action for dizziness when lying on her back.
4. A client with asthma has low-pitched wheezes present on the final half of exhalation. One hour later the client has high-pitched wheezes extending throughout exhalation. This change in assessment indicates to the nurse that the client
- A. Has increased airway obstruction
- B. Has improved airway obstruction
- C. Needs to be suctioned
- D. Exhibits hyperventilation
Correct answer: A
Rationale: The correct answer is A: 'Has increased airway obstruction.' High-pitched wheezes extending throughout exhalation indicate a worsening airway obstruction, leading to increased resistance in the airways. Low-pitched wheezes present on the final half of exhalation may suggest some level of obstruction, but the change to high-pitched wheezes throughout exhalation indicates a progression in the obstruction. Choice B is incorrect as the change in wheeze characteristics signifies deterioration rather than improvement. Choice C is incorrect as suctioning is not indicated based on the wheeze assessment findings. Choice D is incorrect as hyperventilation does not typically present with wheezes and is not supported by the information provided.
5. An unlicensed assistive personnel (UAP) reports to the nurse that a client with a postoperative wound infection has a temperature of 103.8°F, blood pressure 90/70, pulse 124 beats/min, and respirations of 28 breaths/min. When the nurse assesses the client's findings, they include a mottled skin appearance and confusion. Which action should the nurse take first?
- A. Obtain a wound specimen for culture.
- B. Initiate an infusion of intravenous (IV) fluids.
- C. Transfer the client to the ICU.
- D. Assess the client's core temperature.
Correct answer: B
Rationale: The correct action for the nurse to take first is to initiate an infusion of intravenous (IV) fluids. In this scenario, the client is showing signs of sepsis, indicated by a high temperature, low blood pressure, rapid heart rate, and increased respiratory rate. Mottled skin appearance and confusion are also signs of poor perfusion. Initiating IV fluids is crucial in treating sepsis to maintain blood pressure and perfusion. Obtaining a wound specimen for culture (Choice A) can be important but is not the priority at this moment. Transferring the client to the ICU (Choice C) can be considered after stabilizing the client. Assessing the client's core temperature (Choice D) is not the immediate priority compared to addressing the signs of sepsis and poor perfusion.
