HESI Fundamentals 2023 Quizlet
1. When parents call the emergency room to report that a toddler has swallowed drain cleaner, the nurse instructs them to call for emergency transport to the hospital. While waiting for an ambulance, what substance should the nurse suggest the parents give the child sips of?
- A. Tea
- B. Water
- C. Milk
- D. Soda
Correct answer: B
Rationale: The correct answer is B: Water. Giving sips of water can help dilute the drain cleaner while waiting for emergency transport, which may help reduce the potential harm caused by the ingestion. Choices A, C, and D are incorrect because tea, milk, and soda can interact with the chemicals in the drain cleaner or increase the risk of vomiting, which is not recommended in this situation.
2. The nurse is assessing a client with Addison's disease who is weak, dizzy, disoriented, and has dry oral mucous membranes, poor skin turgor, and sunken eyes. Vital signs are blood pressure 94/44, heart rate 123 beats/minute, respiration 22 breaths/minute. Which intervention should the nurse implement first?
- A. Assess extremity strength and resistance
- B. Report a sodium level of 132 mEq/L or mmol/L (SI units)
- C. Measure and record the cardiac QRS complex
- D. Check current finger stick glucose
Correct answer: D
Rationale: The client’s symptoms suggest possible adrenal crisis or hypoglycemia. Checking glucose is a priority to rule out hypoglycemia, which requires immediate intervention. The client is presenting with symptoms indicative of hypoglycemia, which can be life-threatening if not promptly addressed. Assessing extremity strength, reporting sodium levels, or measuring the cardiac QRS complex are not the most urgent actions in this scenario.
3. What is the best initial action for the nurse to take with a manic depressive male client who becomes loud and verbally aggressive towards a nurse?
- A. Have the staff escort the client to his room.
- B. Tell the client that his behavior will be recorded in his record.
- C. Redirect the client by asking him to engage in a game with peers.
- D. Review the medication record for an antipsychotic drug.
Correct answer: C
Rationale: In dealing with a manic depressive client who is being verbally aggressive, the best initial action for the nurse is to redirect the client by engaging him in a more constructive activity, such as playing card games with peers. This approach can help de-escalate the situation, shift the client's focus positively, and provide a distraction from the current behavior. Having the staff escort the client to his room may escalate the situation further. Threatening to record the behavior in his record is not likely to be effective in managing the immediate situation. Reviewing the medication record for an antipsychotic drug is important but would not be the best initial action in this scenario when the client is being verbally aggressive.
4. A nurse reviews the electrolyte results of an assigned client and notes that the potassium level is 5.4 mEq/L. Which of the following would the nurse expect to note on the electrocardiogram as a result of the laboratory value?
- A. ST depression
- B. Inverted T wave
- C. Prominent U wave
- D. Tall peaked T waves
Correct answer: D
Rationale: The correct answer is 'Tall peaked T waves.' Tall peaked T waves are characteristic ECG changes associated with hyperkalemia. In hyperkalemia, the elevated potassium levels affect the myocardium, leading to changes in the ECG. ST depression (Choice A) is more commonly associated with myocardial ischemia or infarction. Inverted T wave (Choice B) is seen in conditions like myocardial ischemia or CNS events. Prominent U wave (Choice C) is typically associated with hypokalemia or certain medications. Therefore, in this scenario, the nurse would expect to note tall peaked T waves on the electrocardiogram due to the elevated potassium level.
5. Which field of biology studies heredity?
- A. Etiology.
- B. Ecology.
- C. Genetics.
- D. Eugenics.
Correct answer: C
Rationale: Genetics is the branch of biology that focuses on the study of heredity and variation in organisms. Etiology (choice A) deals with the causes of diseases, not heredity. Ecology (choice B) is concerned with the relationships between organisms and their environment, not specifically heredity. Eugenics (choice D) is a controversial field that involves improving the genetic quality of the human population through selective breeding, which is different from the study of heredity itself.
