HESI Leadership and Management Quizlet
1. Insulin forces which of the following electrolytes out of the plasma and into the cells?
- A. Calcium
- B. Magnesium
- C. Phosphorus
- D. Potassium
Correct answer: D
Rationale: Insulin forces potassium out of the plasma and into the cells, which can cause hypokalemia. This is because insulin enhances the activity of the sodium-potassium pump in cell membranes, promoting the movement of potassium from the extracellular fluid into the cells. Choices A, B, and C are incorrect as insulin does not directly influence the movement of calcium, magnesium, or phosphorus in the same manner as it does with potassium.
2. What are neurotransmitters?
- A. Chemical messengers that cause brain cells to turn on or off.
- B. Areas of the brain that are responsible for controlling emotions.
- C. Clumps of cells that alert the other brain cells to receive messages.
- D. Web-like structures that provide connections among parts of the brain.
Correct answer: A
Rationale: Neurotransmitters are chemicals in the brain that act as messengers between neurons, influencing various psychological functions. Choice A correctly defines neurotransmitters by stating that they are chemical messengers that cause brain cells to turn on or off. This is the function of neurotransmitters in transmitting signals between neurons. Choices B, C, and D are incorrect because they do not accurately describe neurotransmitters and their role in the brain.
3. You have a patient who has just had a diagnostic arthroscopy. You are instructing him about what to do when he gets home. Which of the following would you NOT instruct him to do?
- A. Resume normal activities within 12 hours so as to help reduce the swelling
- B. Elevate the extremity for 24 – 48 hours
- C. Apply ice to the area involved intermittently
- D. Report severe pain to the physician immediately
Correct answer: A
Rationale: Patients should rest and avoid normal activities for a short period after arthroscopy to allow healing and prevent swelling, which could worsen with early activity. Elevation and icing are recommended post-procedure to reduce swelling and pain. Instructing the patient to resume normal activities within 12 hours could lead to increased swelling and delayed healing. Reporting severe pain is crucial as it could indicate a complication. Therefore, the correct instruction is not to resume normal activities immediately after arthroscopy.
4. A client is recovering from a right-sided mastectomy and is concerned about lymphedema. What should the nurse include in the discharge teaching to minimize this risk?
- A. Encourage wearing tight clothing on the affected arm.
- B. Advise against lifting heavy objects with the affected arm.
- C. Recommend the client sleep on the affected side.
- D. Suggest frequent massage of the affected arm.
Correct answer: B
Rationale: The correct answer is B: Advise against lifting heavy objects with the affected arm. Lifting heavy objects with the affected arm can increase the risk of lymphedema. It is important for clients to avoid activities that strain the affected arm to minimize the risk of developing lymphedema. Choices A, C, and D are incorrect because wearing tight clothing on the affected arm, sleeping on the affected side, and frequent massage of the affected arm can potentially worsen lymphedema or impede the recovery process. Tight clothing can impede lymphatic flow, sleeping on the affected side can restrict circulation, and frequent massage can exacerbate swelling in the arm.
5. Before administering an intramuscular injection, the nurse's finger is stuck with the needle. Which action should the nurse take?
- A. Go to the emergency room to have blood drawn
- B. Prepare the medication using a new syringe
- C. Apply clean gloves before giving the medication
- D. Review the medical history in the client's chart
Correct answer: B
Rationale: In this scenario, if the nurse's finger is stuck with the needle before administering the injection, the correct action is to prepare the medication using a new syringe. This step is crucial to prevent contamination and ensure the safety of the patient. Going to the emergency room to have blood drawn is unnecessary and does not address the immediate issue of contamination. Applying clean gloves is important for infection control but does not address the potential contamination from the needlestick. Reviewing the medical history in the client's chart is important for overall patient care but is not the priority in this situation where immediate action is required to prevent harm.
