Nokea
The nurse has been assigned the following patients. Which patients require assessment of blood glucose control as a nursing priority? (Select all that apply.)
- A. 18-year-old male who has undergone surgical correction of a fractured femur
- B. 29-year-old female who is undergoing evaluation for pheochromocytoma
- C. 43-year-old male with acute pancreatitis who is receiving total parenteral nutrition (TPN)
- D. 62-year-old morbidly obese female who underwent a hysterectomy for ovarian cancer
Correct Answer: C
Rationale: The correct answer is C because the patient with acute pancreatitis receiving TPN is at risk for hyperglycemia due to the high glucose content in TPN. Monitoring blood glucose levels is crucial to prevent complications.
Explanation for why other choices are incorrect:
A: The 18-year-old male post-surgery for a fractured femur does not have a direct correlation to blood glucose control assessment.
B: The 29-year-old female undergoing evaluation for pheochromocytoma is not directly related to blood glucose control assessment.
D: The 62-year-old morbidly obese female post-hysterectomy for ovarian cancer does not specifically require immediate blood glucose control assessment.

The patient has a temporary percutaneous catheter in place for treatment of acute kidney injury. The catheter has been in place for 5 days. The nurse should
- A. prepare to assist with a routine dialysis catheter change.
- B. evaluate the patient for signs and symptoms of infection.
- C. teach the patient that the catheter is designed for long-term use.
- D. use one of the three lumens for fluid administration.
Correct Answer: B
Rationale: The correct answer is B: evaluate the patient for signs and symptoms of infection. After 5 days, infection risk increases. Signs of infection include fever, redness, swelling, and tenderness at the catheter site. Monitoring for these signs is crucial to prevent complications. A: Routine dialysis catheter change is not indicated after 5 days. C: Teaching long-term use is incorrect as temporary catheters are not meant for extended use. D: Using lumens for fluid administration can increase infection risk and is not recommended.
Continuous renal replacement therapy (CRRT) differs from conventional intermittent hemodialysis in that
- A. a hemofilter is used to facilitate ultrafiltration.
- B. it provides faster removal of solute and water.
- C. it does not allow diffusion to occur.
- D. the process removes solutes and water slowly.
Correct Answer: D
Rationale: Step-by-step rationale:
1. CRRT removes solutes and water slowly to avoid hemodynamic instability.
2. Slow removal better tolerates fluid and electrolyte shifts in critically ill patients.
3. Unlike intermittent hemodialysis, CRRT provides continuous, gentle therapy.
4. Choice A is incorrect as both CRRT and intermittent hemodialysis use a hemofilter.
5. Choice B is incorrect as CRRT does not provide faster solute and water removal.
6. Choice C is incorrect as CRRT allows for diffusion to occur, albeit at a slower rate.
Summary:
Continuous renal replacement therapy (CRRT) removes solutes and water slowly to prevent hemodynamic instability, making it a gentler and more continuous process compared to intermittent hemodialysis. The other choices are incorrect as CRRT does use a hemofilter, does not provide faster removal, and still allows for diffusion to occur.
A college student was admitted to the emergency department after being found unconscious by a roommate. The roommate informs emergency medical personnel that the student has diabetes and has been experiencing flulike symptoms, including vomiting, since yesterday. The patient had been up all night studying for exams. The patient used the last diabetes testing supplies 3 days ago and has not had time to go to the pharmacy to refill prescription supplies. Based upon the history, which laboratory findings would be anticipated in this client? (Select all that apply.)
- A. Blood glucose: 43 mg/dL
- B. Blood glucose: 524 mg/dL
- C. HCO —: 10 mEq/L
- D. PaCO : 37 mm Hg
Correct Answer: B
Rationale: The correct answer is B: Blood glucose: 524 mg/dL. The patient likely has diabetic ketoacidosis (DKA) due to missed insulin doses, stress, and illness leading to high blood glucose levels. DKA is characterized by hyperglycemia, ketosis, and metabolic acidosis. A low blood glucose level (Choice A) is not consistent with DKA. HCO3- of 10 mEq/L (Choice C) indicates metabolic acidosis, but it's not specific to DKA. A PaCO2 of 37 mm Hg (Choice D) is within the normal range and not directly related to DKA.
The patient has been admitted to the hospital with nausea and vomiting that started 5 days earlier. Blood pressure is 80/44 mm Hg and heart rate is 122 beats/min; the patient has not voided in 8 hours, and the bladder is not distended. The nurse anticipates a prescription for “stat” administration of
- A. a blood transfusion.
- B. fluid replacement with 0.45% saline.
- C. infusion of an inotropic agent.
- D. an antiemetic.
Correct Answer: B
Rationale: The correct answer is B: fluid replacement with 0.45% saline. The patient's symptoms suggest dehydration and hypovolemia, indicated by low blood pressure, elevated heart rate, and lack of urine output. Fluid replacement with isotonic saline would help restore intravascular volume and improve blood pressure. Blood transfusion (A) is not indicated without evidence of significant blood loss. Inotropic agents (C) are used to improve cardiac function, which is not the primary issue in this case. Antiemetics (D) may help with nausea and vomiting but do not address the underlying cause of hypovolemia.
The nurse is assessing a patient with a new arteriovenous fistula, but does not hear a bruit or feel a thrill. Pulses distal to the fistula are not palpable. The nurse should
- A. reassess the patient in an hour.
- B. raise the arm above the level of the patient’s heart.
- C. notify the provider immediately.
- D. apply warm packs to the fistula site and reassess.
Correct Answer: C
Rationale: The correct answer is C: notify the provider immediately. Lack of bruit, thrill, and distal pulse indicates potential complications like thrombosis or occlusion in the arteriovenous fistula. Prompt provider notification is crucial for timely intervention to prevent further complications such as ischemia or access failure. Reassessing the patient in an hour (A) may delay necessary intervention. Raising the arm above the level of the patient's heart (B) does not address the underlying issue. Applying warm packs (D) could worsen the situation if there is a clot present.
