HESI RN Exit Exam 2023 Capstone
1. Which medication should the nurse withhold if the client's serum potassium level is 6.2 mEq/L?
- A. Losartan
- B. Spironolactone
- C. Metoprolol
- D. Furosemide
Correct answer: B
Rationale: The correct answer is B: Spironolactone. Spironolactone is a potassium-sparing diuretic that can lead to hyperkalemia. With potassium levels already elevated at 6.2 mEq/L, withholding Spironolactone is essential to prevent further increase in potassium levels, which could result in dangerous cardiac arrhythmias. Losartan (Choice A) is an angiotensin receptor blocker and does not directly affect potassium levels. Metoprolol (Choice C) is a beta-blocker and also does not impact potassium levels significantly. Furosemide (Choice D) is a loop diuretic that can actually lower potassium levels, so it would not be the medication to withhold in this case.
2. After an older client receives treatment for drug toxicity, the healthcare provider prescribes a 24-hour creatinine clearance test. Before starting the urine collection, the nurse noted that the client's serum creatinine was 0.3 mg/dL. Which action should the nurse implement?
- A. Check the client's urine output hourly
- B. Instruct the client to increase fluid intake
- C. Notify the healthcare provider of the results
- D. Start the 24-hour urine collection
Correct answer: C
Rationale: A serum creatinine level of 0.3 mg/dL is abnormally low, indicating potential issues with the interpretation of the creatinine clearance test. It is crucial for the nurse to notify the healthcare provider of this result before proceeding with the 24-hour urine collection. Checking urine output, instructing the client to increase fluid intake, or starting the urine collection without consulting the healthcare provider could lead to incorrect test results and misinterpretation of the client's renal function.
3. The nurse is conducting intake interviews of children at a city clinic. Which child is most susceptible to contracting lead poisoning?
- A. An 8-year-old living in a housing project.
- B. A 2-year-old playing on aging playground equipment.
- C. An adolescent working in a paint factory.
- D. A 10-year-old with Type 1 diabetes.
Correct answer: B
Rationale: The correct answer is B. Young children, like the 2-year-old playing on aging playground equipment, are more susceptible to lead poisoning from environmental sources due to their behaviors like hand-to-mouth contact and exploratory behaviors. Choices A, C, and D are less likely to be at high risk for lead poisoning compared to young children due to differences in exposure levels and behaviors related to potential sources of lead contamination.
4. The nurse is administering an IV medication to a client with a history of anaphylaxis. Which intervention is most important for the nurse to implement?
- A. Stay with the client throughout the infusion.
- B. Keep emergency resuscitation equipment at the bedside.
- C. Obtain the client's allergy history.
- D. Ask the client about past allergic reactions to medications.
Correct answer: B
Rationale: Keeping emergency resuscitation equipment at the bedside is crucial in case the client experiences anaphylaxis during the infusion. While staying with the client throughout the infusion (Choice A) is important, having immediate access to emergency equipment takes priority in this situation. Obtaining the client's allergy history (Choice C) and asking about past allergic reactions to medications (Choice D) are relevant but do not address the immediate need for emergency intervention in case of anaphylaxis.
5. While auscultating the lung sounds of a 5-year-old Chinese boy who recently completed antibiotic therapy for pneumonia, the nurse notices symmetrical, round, bruise-like blemishes on his chest. What action is best for the nurse to take?
- A. Identify the antibiotics used for treating the pneumonia.
- B. Inquire about the use of alternative treatment methods.
- C. Ask the parents if the child has been in a recent accident.
- D. Report suspected child abuse to the authorities.
Correct answer: B
Rationale: Inquiring about the use of alternative treatment methods is essential to understand cultural practices and provide holistic care. It allows the nurse to gather more information about the blemishes and potentially uncover traditional or alternative healing approaches that the family may have used. This approach demonstrates cultural sensitivity and a comprehensive assessment before making assumptions or taking further actions. Identifying the antibiotics used for treating pneumonia (Choice A) is not immediately necessary in this context as the focus is on the blemishes. Asking about a recent accident (Choice C) assumes a traumatic cause without evidence. Reporting suspected child abuse (Choice D) is premature without further assessment or evidence of abuse.
