A client is postoperative following cataract surgery. Which of the following instructions should the nurse include?
- A. Avoid lying flat for 24 hours after surgery.
- B. Avoid bending at the waist.
- C. Wear an eye patch at night for 1 week.
- D. Sleep on your affected side to reduce discomfort.
Correct Answer: B
Rationale: The correct instruction that the nurse should include for a client postoperative following cataract surgery is to avoid bending at the waist. Bending at the waist can increase intraocular pressure, which is not recommended after cataract surgery. Choices A, C, and D are incorrect because lying flat for 24 hours after surgery may not be necessary, wearing an eye patch at night for a week is not a standard postoperative instruction for cataract surgery, and sleeping on the affected side may not necessarily reduce discomfort and can increase pressure on the eye.

What is the best way to monitor for infection in a patient with a central line?
- A. Check the central line site daily
- B. Monitor the patient's vital signs
- C. Check the central line dressing every other day
- D. Check for signs of sepsis
Correct Answer: A
Rationale: The correct answer is A: Check the central line site daily. Monitoring the central line site daily is crucial in detecting early signs of infection, such as redness, swelling, tenderness, or drainage. By checking the site regularly, healthcare providers can take prompt action to prevent complications. Choice B, monitoring the patient's vital signs, while important in assessing overall health, may not specifically indicate an infection related to the central line. Choice C, checking the central line dressing every other day, may not be frequent enough to catch early signs of infection. Choice D, checking for signs of sepsis, is important but represents a more severe stage of infection and may occur after local signs at the central line site have already manifested.
A healthcare provider is reviewing laboratory results for a client who is receiving heparin therapy. Which of the following results indicates that the medication is effective?
- A. Platelets 250,000/mm³
- B. aPTT 60 seconds
- C. Hemoglobin 15 g/dL
- D. INR 1.5
Correct Answer: B
Rationale: An aPTT of 60 seconds indicates that the client is receiving an effective dose of heparin. The activated partial thromboplastin time (aPTT) measures the time it takes for blood to clot and is used to monitor heparin therapy. A therapeutic range for aPTT during heparin therapy is usually 1.5 to 2 times the control value, which is around 25-35 seconds. Platelets, hemoglobin, and INR values are not direct indicators of the effectiveness of heparin therapy.
A nurse is caring for a client who has deep vein thrombosis. Which of the following instructions should the nurse include in the plan of care?
- A. Limit the client's fluid intake to 1500 mL per day.
- B. Avoid massaging the affected extremity to relieve pain.
- C. Do not apply cold packs to the client's affected extremity.
- D. Elevate the client's affected extremity when in bed.
Correct Answer: D
Rationale: The correct answer is to elevate the client's affected extremity when in bed. Elevating the extremity helps to reduce swelling and improve venous return in clients with DVT. Limiting fluid intake to 1500 mL per day (Choice A) is not directly related to managing DVT. Massaging the affected extremity (Choice B) can dislodge a clot and lead to serious complications. Applying cold packs (Choice C) can vasoconstrict blood vessels, potentially worsening the condition by reducing blood flow.
Which lab test is used to assess renal function?
- A. Check blood glucose levels
- B. Monitor serum creatinine
- C. Monitor BUN
- D. Check electrolyte levels
Correct Answer: B
Rationale: The correct answer is B: Monitor serum creatinine. Serum creatinine is a key indicator of renal function as it reflects the glomerular filtration rate. An increase in serum creatinine levels indicates impaired kidney function. Checking blood glucose levels (choice A) is not specific to assessing renal function but is used to diagnose diabetes. Monitoring BUN (choice C) is important but not as specific as serum creatinine in assessing renal function. Checking electrolyte levels (choice D) is essential in assessing kidney function but is not as specific as monitoring serum creatinine.
A healthcare professional is reviewing the laboratory data of a client who has diabetes mellitus. Which of the following laboratory tests is an indicator of long-term disease management?
- A. Postprandial blood glucose
- B. Glycosylated hemoglobin (HbA1c)
- C. Glucose tolerance test
- D. Fasting blood glucose
Correct Answer: B
Rationale: Glycosylated hemoglobin (HbA1c) is the most accurate test for long-term management of blood glucose levels in individuals with diabetes mellitus. HbA1c reflects average blood glucose levels over the past 2-3 months, providing valuable information on the effectiveness of treatment and disease control. Postprandial blood glucose, glucose tolerance test, and fasting blood glucose are essential for monitoring blood glucose levels at specific times but do not offer the same insight into long-term disease management as HbA1c.
