1. What action should the nurse take for a patient admitted with diabetic ketoacidosis exhibiting rapid, deep respirations?
- A. Administer the prescribed PRN lorazepam (Ativan).
- B. Start the prescribed PRN oxygen at 2 to 4 L/min.
- C. Administer the prescribed normal saline bolus and insulin.
- D. Encourage the patient to practice guided imagery for relaxation.
Correct answer: C
Rationale: The correct action for a patient with diabetic ketoacidosis and rapid, deep (Kussmaul) respirations is to administer a normal saline bolus and insulin. The rapid, deep respirations indicate a metabolic acidosis, which requires correction with a saline bolus to prevent hypovolemia and insulin to facilitate glucose re-entry into cells. Oxygen therapy is not necessary since the increased respiratory rate is compensatory and not due to hypoxemia. Encouraging relaxation techniques or administering lorazepam are inappropriate as they can worsen the acidosis by suppressing the compensatory respiratory effort.
2. A client with diabetes has a new prescription for 14 units of regular insulin and 28 units of NPH insulin subcutaneously at breakfast daily. What is the total number of units of insulin that should be prepared in the insulin syringe?
- A. 42 units
- B. 14 units
- C. 28 units
- D. 32 units
Correct answer: A
Rationale: To calculate the total number of units of insulin, you need to add the 14 units of regular insulin to the 28 units of NPH insulin, which equals 42 units. Therefore, the nurse should prepare 42 units of insulin in the syringe for the client.
3. A client's telemetry monitor indicates the sudden onset of ventricular fibrillation. Which assessment finding should the nurse anticipate?
- A. Bounding erratic pulse.
- B. Regularly irregular pulse.
- C. Thready irregular pulse.
- D. No palpable pulse.
Correct answer: D
Rationale: Ventricular fibrillation is a life-threatening arrhythmia characterized by chaotic, asynchronous contractions of the ventricles, resulting in ineffective cardiac output. This leads to the absence of a palpable pulse. Nurses should be prepared to initiate immediate interventions such as defibrillation to restore normal cardiac rhythm in a client experiencing ventricular fibrillation.
4. A patient with chronic heart failure is prescribed furosemide. What is the primary action of this medication?
- A. Increase cardiac output
- B. Reduce fluid retention
- C. Decrease heart rate
- D. Lower blood pressure
Correct answer: B
Rationale: Furosemide is a loop diuretic that acts by inhibiting sodium and chloride reabsorption in the loop of Henle, leading to increased diuresis. By reducing fluid retention, furosemide helps decrease the workload on the heart in patients with chronic heart failure. This medication does not directly increase cardiac output, decrease heart rate, or lower blood pressure as its primary action.
5. An elderly female client comes to the clinic for a regular check-up. The client tells the nurse that she has increased her daily doses of acetaminophen (Tylenol) for the past month to control joint pain. Based on this client's comment, what previous lab values should the nurse compare with today's lab report?
- A. Look at last quarter's hemoglobin and hematocrit to assess for dehydration.
- B. Look for an increase in today's LDH compared to the previous one to assess for possible liver damage.
- C. Expect to find an increase in today's APTT compared to last quarter's due to bleeding.
- D. Determine if there is a decrease in serum potassium due to renal compromise.
Correct answer: B
Rationale: When a client increases their daily doses of acetaminophen for joint pain, it raises concerns about possible liver damage due to acetaminophen overdose. LDH (Lactate Dehydrogenase) levels can indicate liver function, so comparing today's levels with previous ones can help assess for liver damage caused by acetaminophen overuse.
