Nursing Elites

1. A nurse cares for a client with diabetes mellitus who is prescribed metformin (Glucophage) and is scheduled for an intravenous urography. Which action should the nurse take first?

• A. Contact the provider and recommend discontinuing the metformin.
• B. Keep the client NPO for at least 6 hours prior to the examination.
• C. Check the client’s capillary artery blood glucose and administer prescribed insulin.
• D. Administer intravenous fluids to dilute and increase the excretion of dye.

Correct answer: A

Rationale: Metformin can cause lactic acidosis and renal impairment as the result of an interaction with the dye. This drug must be discontinued for 48 hours before the procedure and not started again after the procedure until urine output is well established. The client’s health care provider needs to provide alternative therapy for the client until the metformin can be resumed. Keeping the client NPO, checking the client’s blood glucose, and administering intravenous fluids should be part of the client’s plan of care, but are not the priority, as the examination should not occur while the client is still taking metformin.

2. The client with chronic renal failure is receiving peritoneal dialysis. Which of the following is the most important action for the nurse to take?

• A. Administer the prescribed antibiotics.
• B. Monitor for signs of infection.
• C. Encourage the client to increase fluid intake.
• D. Monitor the client's weight daily.

Correct answer: B

Rationale: Monitoring for signs of infection is crucial in clients undergoing peritoneal dialysis. Peritonitis is a severe complication associated with peritoneal dialysis, making it essential to promptly identify any signs of infection, such as abdominal pain, cloudy dialysate, fever, and an elevated white blood cell count. Administering antibiotics without proper assessment can lead to antibiotic resistance and should not be the initial action. Encouraging increased fluid intake may not be appropriate without assessing the client's fluid status. Monitoring weight alone does not address the immediate risk of peritonitis in a client undergoing peritoneal dialysis.

3. Which of the following lab values would be most concerning in a patient receiving heparin therapy?

• A. Elevated hemoglobin levels.
• B. Low platelet count.
• C. High potassium levels.
• D. Low sodium levels.

Correct answer: B

Rationale: A low platelet count is most concerning in patients receiving heparin therapy due to the risk of heparin-induced thrombocytopenia. Heparin can sometimes cause a drop in platelet count, leading to a potentially serious condition where blood does not clot as it should. This can result in excessive bleeding or clot formation in blood vessels. Elevated hemoglobin levels, high potassium levels, and low sodium levels are not typically associated with heparin therapy and are less likely to cause immediate concerns or complications in this context.

4. Which of the following is a common sign of meningitis?

• A. Joint pain.
• B. Severe headache.
• C. Stiff neck.
• D. Coughing up blood.

Correct answer: C

Rationale: A stiff neck is a common sign of meningitis due to inflammation of the meninges. Meningitis typically presents with symptoms such as fever, severe headache, nausea, vomiting, sensitivity to light, and a stiff neck. Joint pain (Choice A) is not a typical symptom of meningitis and is more commonly associated with other conditions. While severe headache (Choice B) can be a symptom of meningitis, it is not as specific as a stiff neck. Coughing up blood (Choice D) is not a typical sign of meningitis and may indicate other respiratory or cardiovascular issues.

5. The healthcare provider notes a blood pressure of 160/90 mm Hg in a patient taking a thiazide diuretic. The patient reports taking an herbal medication that a friend recommended. Which herbal product is likely, given this patient’s blood pressure?

• A. Ginkgo
• B. Hawthorn
• C. Licorice
• D. St. John’s wort

Correct answer: A

Rationale: The correct answer is A: Ginkgo. Increased blood pressure can result when ginkgo is used in combination with a thiazide diuretic. Option B (Hawthorn) is incorrect because hawthorn is more commonly associated with lowering blood pressure. Option C (Licorice) is incorrect because licorice can lead to sodium and water retention, potentially exacerbating hypertension. Option D (St. John’s wort) is incorrect as it is not typically associated with significant blood pressure effects.
