HESI RN Nursing Leadership and Management Exam 6
1. A client with type 1 diabetes mellitus presents to the emergency department with symptoms of diabetic ketoacidosis (DKA). Which of the following interventions should the nurse implement first?
- A. Administer intravenous insulin
- B. Start an intravenous line and infuse normal saline
- C. Monitor serum potassium levels
- D. Obtain an arterial blood gas (ABG)
Correct answer: B
Rationale: The correct first intervention in a client with DKA is to start an intravenous line and infuse normal saline for fluid resuscitation. This is crucial to restore intravascular volume and improve perfusion, addressing the dehydration and electrolyte imbalances commonly seen in DKA. Administering insulin without addressing the dehydration can lead to further complications. Monitoring serum potassium levels is important but is not the first priority; potassium levels can shift with fluid resuscitation. Obtaining an arterial blood gas (ABG) is helpful in assessing acid-base status but is not the initial priority compared to fluid resuscitation.
2. 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.
3. A client with chronic kidney disease is prescribed erythropoietin. What lab value should the nurse monitor to evaluate the effectiveness of the therapy?
- A. White blood cell count.
- B. Hemoglobin level.
- C. Serum creatinine level.
- D. Platelet count.
Correct answer: B
Rationale: Erythropoietin therapy stimulates red blood cell production in clients with chronic kidney disease. Hemoglobin levels should be monitored to assess the effectiveness of the therapy and ensure the client is not developing anemia. Increased hemoglobin levels indicate successful treatment, whereas very high levels may suggest erythropoietin is overcorrecting the anemia. Monitoring the white blood cell count is not directly related to erythropoietin therapy for anemia. Serum creatinine level is used to assess kidney function rather than the effectiveness of erythropoietin therapy. Platelet count is not typically affected by erythropoietin therapy and is not a key indicator of its effectiveness.
4. During the infusion of a second unit of packed red blood cells, the client's temperature increases from 99 to 101.6 F. Which intervention should the nurse implement?
- A. Stop the transfusion and start a saline infusion.
- B. Administer antipyretics and continue the transfusion.
- C. Monitor the client’s vital signs every 15 minutes.
- D. Notify the healthcare provider and continue the transfusion.
Correct answer: A
Rationale: An increase in temperature during a transfusion may indicate a transfusion reaction, which can be serious. Stopping the transfusion and starting a saline infusion is the priority action to prevent further complications and address the potential adverse reaction. Administering antipyretics (choice B) may mask the symptoms of a transfusion reaction, delaying appropriate treatment. While monitoring vital signs (choice C) is important, stopping the transfusion takes precedence to prevent harm. Notifying the healthcare provider (choice D) is essential but should not delay the immediate intervention of stopping the transfusion and starting a saline infusion.
5. Which of the following hormone ratios is MOST likely to be increased in a patient with PCOS?
- A. Progesterone/estrogen
- B. LH/FSH
- C. FSH/LH
- D. Glucagon/insulin
Correct answer: B
Rationale: In patients with Polycystic Ovary Syndrome (PCOS), the LH/FSH ratio is most likely to be increased. This hormonal imbalance is a key characteristic of PCOS, where elevated LH levels relative to FSH contribute to the pathophysiology of the condition. Choice A, progesterone/estrogen ratio, is not typically a defining feature of PCOS. Choice C, FSH/LH ratio, is the reverse of what is commonly observed in PCOS. Choice D, glucagon/insulin ratio, is not directly related to the hormonal imbalances seen in PCOS.
