HESI 799 RN Exit Exam
1. The nurse is caring for a client with a history of myocardial infarction who is complaining of chest pain. Which intervention should the nurse implement first?
- A. Administer oxygen therapy as prescribed.
- B. Administer nitroglycerin sublingually as prescribed.
- C. Obtain an electrocardiogram (ECG).
- D. Assess the client's level of consciousness.
Correct answer: C
Rationale: Obtaining an electrocardiogram (ECG) is the first priority in assessing for ischemia or infarction in a client with chest pain and a history of myocardial infarction. This diagnostic test provides crucial information about the heart's electrical activity and helps in identifying any acute cardiac changes. Administering oxygen therapy and nitroglycerin can be important interventions, but obtaining an ECG takes precedence as it directly assesses the client's cardiac status. Assessing the client's level of consciousness is also essential, but in this scenario, assessing for cardiac indications through an ECG is the initial step.
2. The nurse is caring for a client with chronic kidney disease (CKD) who is receiving erythropoietin therapy. Which laboratory value should be monitored closely?
- A. Serum potassium
- B. Hemoglobin
- C. Serum sodium
- D. White blood cell count
Correct answer: A
Rationale: The correct answer is A: Serum potassium. When a client with chronic kidney disease is undergoing erythropoietin therapy, monitoring serum potassium levels is crucial. Erythropoietin can stimulate red blood cell production, which may lead to an increase in potassium levels, predisposing the client to hyperkalemia. Monitoring serum potassium levels helps in early detection of hyperkalemia and appropriate intervention. Choices B, C, and D are incorrect because although hemoglobin, serum sodium, and white blood cell count are important parameters to monitor in various clinical conditions, they are not specifically associated with erythropoietin therapy in chronic kidney disease.
3. The nurse is assessing a client with left-sided heart failure. Which laboratory value is most concerning?
- A. Serum creatinine of 1.5 mg/dL
- B. Serum sodium of 136 mEq/L
- C. Serum potassium of 5.5 mEq/L
- D. Hemoglobin of 12 g/dL
Correct answer: C
Rationale: A serum potassium level of 5.5 mEq/L is most concerning in a client with left-sided heart failure as it indicates hyperkalemia, requiring immediate intervention. Hyperkalemia can lead to life-threatening cardiac arrhythmias, which can exacerbate heart failure. Serum creatinine of 1.5 mg/dL is slightly elevated but not as immediately concerning as hyperkalemia. Serum sodium of 136 mEq/L is within the normal range. Hemoglobin of 12 g/dL is also within the normal range and not directly related to the client's left-sided heart failure.
4. The nurse plans to administer a scheduled dose of metoprolol (Toprol SR) at 0900 to a client with hypertension. At 0800, the nurse notes that the client's telemetry pattern shows a second-degree heart block with a ventricular rate of 50. What action should the nurse take?
- A. Administer the Toprol immediately and monitor the client until the heart rate increases.
- B. Provide the dose of Toprol as scheduled and assign a UAP to monitor the client's BP q30 minutes.
- C. Give the Toprol as scheduled if the client's systolic blood pressure reading is greater than 180.
- D. Hold the scheduled dose of Toprol and notify the healthcare provider of the telemetry pattern.
Correct answer: D
Rationale: In clients with second-degree heart block, beta blockers such as metoprolol (Toprol SR) are contraindicated as they can further decrease the heart rate. Administering metoprolol in this situation can lead to serious complications. The correct action for the nurse to take is to hold the scheduled dose of Toprol and promptly notify the healthcare provider of the telemetry pattern. This ensures patient safety and appropriate management of the cardiac condition. Choices A, B, and C are incorrect because administering Toprol despite the heart block can worsen the condition and pose a risk to the client's health.
5. The mother of an adolescent tells the clinic nurse, 'My son has athlete's foot. I have been applying triple antibiotic ointment for two days, but there has been no improvement.' What instruction should the nurse provide?
- A. Antibiotics take two weeks to become effective against fungal infections like athlete's foot.
- B. Continue using the ointment for a full week, even after the symptoms disappear.
- C. Applying too much ointment can reduce its effectiveness. Apply a thin layer to prevent maceration.
- D. Stop using the ointment and encourage complete drying of the feet and wearing clean socks.
Correct answer: D
Rationale: The correct answer is D. Athlete's foot (tinea pedis) is a fungal infection, not a bacterial infection that would respond to antibiotics. The primary management involves keeping the feet well-ventilated, dry after bathing, and wearing clean socks to prevent moisture buildup, which promotes fungal growth. Using an antibiotic ointment like triple antibiotic ointment is not effective for treating athlete's foot. Therefore, the nurse should advise the mother to stop using the antibiotic ointment and focus on promoting proper foot hygiene to manage the fungal infection. Choices A, B, and C are incorrect as they do not address the fungal nature of athlete's foot and the ineffectiveness of antibiotic ointments in its treatment.
