HESI 799 RN Exit Exam Capstone
1. An adolescent who was diagnosed with diabetes mellitus Type 1 at the age of 9 is admitted to the hospital in diabetic ketoacidosis. Which occurrence is the most likely cause of ketoacidosis?
- A. Had a cold and ear infection for the past two days
- B. Missed a dose of insulin
- C. Did not follow dietary restrictions
- D. Overexerted during exercise
Correct answer: A
Rationale: The correct answer is A. Infections, like a cold and ear infection, increase the body's metabolic needs and insulin resistance, making diabetic ketoacidosis (DKA) more likely. While missing insulin doses or not following dietary restrictions can trigger DKA, an illness is the most common precipitating factor in pediatric Type 1 diabetes. Option B is less likely as missing insulin can lead to hyperglycemia but might not be the immediate cause of ketoacidosis. Option C can contribute to DKA over time, but the acute trigger is usually an illness. Option D, overexertion during exercise, is less likely to cause DKA compared to an infection.
2. A client with a history of adrenal insufficiency is admitted with acute adrenal crisis. The client complains of nausea and joint pain, vital signs show a temperature of 102°F, heart rate of 138, and blood pressure of 80/60. Which intervention should the nurse implement first?
- A. Obtain an analgesic prescription.
- B. Infuse an intravenous fluid bolus.
- C. Administer PRN oral antipyretic.
- D. Cover the client with a cooling blanket.
Correct answer: B
Rationale: In acute adrenal crisis, the priority intervention is to infuse an intravenous fluid bolus to address the hypotension (blood pressure of 80/60) and help stabilize the client's condition. Adequate fluid volume is crucial in managing adrenal insufficiency crisis. Options A, C, and D do not directly address the hypotension and fluid volume depletion that are critical in this situation. Analgesics, antipyretics, and cooling blankets may be considered later, but the immediate focus should be on fluid resuscitation.
3. A client with heart failure is prescribed furosemide. The nurse notes that the client's potassium level is 3.1 mEq/L. What is the nurse's priority action?
- A. Administer a potassium supplement
- B. Encourage the client to eat potassium-rich foods
- C. Hold the next dose of furosemide
- D. Increase the client's fluid intake
Correct answer: A
Rationale: A potassium level of 3.1 mEq/L is considered low, indicating hypokalemia. Administering a potassium supplement is the nurse's priority action to prevent complications such as cardiac arrhythmias associated with low potassium levels. Encouraging the client to eat potassium-rich foods is beneficial in the long term but may not rapidly correct the low potassium level. Holding the next dose of furosemide may worsen the client's heart failure symptoms. Increasing the client's fluid intake is not the priority action in this situation; addressing the low potassium level takes precedence to prevent potential serious complications.
4. The nurse is caring for a client with chronic obstructive pulmonary disease (COPD) who is receiving oxygen therapy. Which assessment finding indicates that the client's oxygenation is improving?
- A. Pulse oximetry reading of 94%
- B. Heart rate increases from 80 to 90 beats per minute
- C. Respiratory rate increases from 16 to 20 breaths per minute
- D. Client reports increased energy levels
Correct answer: A
Rationale: A pulse oximetry reading of 94% indicates adequate oxygenation. Monitoring oxygen saturation is the most objective way to assess the effectiveness of oxygen therapy. Choices B, C, and D do not directly reflect the client's oxygenation status. An increase in heart rate or respiratory rate may indicate increased work of breathing or stress on the body. The client reporting increased energy levels is subjective and may not directly correlate with improved oxygenation.
5. A client with a venous leg ulcer is receiving compression therapy. What assessment finding requires immediate intervention?
- A. Decreased pain and increased redness around the ulcer.
- B. Increased serous drainage from the ulcer site.
- C. Cool extremities and weak peripheral pulses.
- D. Pitting edema around the ulcer site.
Correct answer: C
Rationale: The correct answer is C. Cool extremities and weak peripheral pulses indicate compromised circulation, possibly due to inadequate arterial blood supply. This finding requires immediate intervention to prevent further complications such as tissue damage or non-healing ulcers. Option A, decreased pain and increased redness, can be a sign of improving wound condition. Option B, increased serous drainage, may indicate a normal part of the healing process. Option D, pitting edema, is common in venous leg ulcers and may not require immediate intervention unless severe and accompanied by other concerning symptoms.
