HESI RN CAT Exit Exam
1. A college student who is diagnosed with a vaginal infection and vulva irritation describes the vaginal discharge as having a 'cottage cheese' appearance. Which prescription should the nurse implement first?
- A. Cleanse the perineum with warm soapy water 3 times per day
- B. Instill the first dose of nystatin (Mycostatin) vaginally per applicator
- C. Perform a glucose measurement using a capillary blood sample
- D. Obtain a blood specimen for sexually transmitted diseases (STDs)
Correct answer: B
Rationale: The correct answer is to instill the first dose of nystatin vaginally per applicator. Nystatin is an antifungal medication used to treat yeast infections, which are characterized by 'cottage cheese' discharge. Cleansing the perineum with warm soapy water may help with hygiene but does not address the underlying infection. Performing a glucose measurement is not relevant to the diagnosis of a vaginal infection. Obtaining a blood specimen for STDs is not the priority in this scenario as the symptoms described are indicative of a yeast infection.
2. A client with type 1 diabetes is admitted with diabetic ketoacidosis (DKA). Which clinical finding is most concerning?
- A. Serum glucose of 500 mg/dL
- B. Serum glucose of 600 mg/dL
- C. Serum potassium of 5.5 mEq/L
- D. Serum bicarbonate of 18 mEq/L
Correct answer: D
Rationale: A serum bicarbonate level of 18 mEq/L is most concerning in a client with DKA as it indicates metabolic acidosis, requiring immediate intervention. In DKA, the body produces excess ketones, leading to metabolic acidosis. A low serum bicarbonate level is a key indicator of this acid-base imbalance. Elevated serum glucose levels are expected in DKA but are managed through insulin therapy. Serum potassium levels can fluctuate in DKA due to insulin deficiency, but a value of 5.5 mEq/L is not as immediately concerning as metabolic acidosis. Therefore, the most critical finding in this scenario is the low serum bicarbonate level.
3. The healthcare provider is preparing to administer a scheduled dose of digoxin to a 4-year-old child with heart failure. The healthcare provider notes that the child’s heart rate is 70 beats per minute. What should the healthcare provider do next?
- A. Administer the medication as prescribed
- B. Hold the medication and notify the healthcare provider
- C. Recheck the heart rate in 30 minutes
- D. Administer half of the prescribed dose
Correct answer: B
Rationale: In pediatric patients, digoxin administration is guided by the heart rate. If the child's heart rate is below the established threshold, which is typically 90-100 beats per minute in a 4-year-old, the medication should be withheld, and the healthcare provider should be notified for further evaluation and instructions. Choice A is incorrect because administering the medication when the heart rate is low can lead to adverse effects. Rechecking the heart rate in 30 minutes (Choice C) may delay necessary intervention if the heart rate remains low. Administering half of the prescribed dose (Choice D) is not recommended without healthcare provider guidance.
4. Which of the following is a common cause of chronic liver disease?
- A. Alcohol abuse.
- B. Hepatitis C infection.
- C. Obesity.
- D. Smoking.
Correct answer: B
Rationale: Hepatitis C infection is a common cause of chronic liver disease due to its long-term effects on the liver. Hepatitis C can lead to liver inflammation, fibrosis, cirrhosis, and even liver cancer. Alcohol abuse can also cause liver damage, but hepatitis C infection is specifically known for its chronic impact on liver health. Obesity and smoking, while detrimental to overall health, are not typically direct causes of chronic liver disease like hepatitis C infection.
5. The nurse is preparing a discharge teaching plan for a liver transplant client. Which instruction is most important to include in this plan?
- A. Ensure daily follow-up with the healthcare provider
- B. Take immunosuppressant medications as prescribed
- C. Avoid crowds for the first two months after surgery
- D. Return to work in three months
Correct answer: B
Rationale: The most critical instruction to include in the discharge teaching plan for a liver transplant client is to take immunosuppressant medications as prescribed. This is vital to prevent organ rejection and ensure the success of the transplant. While ensuring daily follow-up with the healthcare provider is important for monitoring progress, avoiding crowds for the first two months after surgery helps reduce the risk of infections but is not as crucial as medication adherence. Returning to work in three months is a consideration but not the most important aspect immediately post-transplant.
