A nurse is caring for a client who is taking triamterene.
For which of the following laboratory values should the nurse withhold the medication?

Sodium 142 mEq/L.

BUN 16 mg/dL.

Potassium 5.3 mEq/L.

Albumin 4 g/dL.

Answer and Explanation

The Correct Answer is C

This is a high level of potassium in the blood (the normal range is 3.5 to 5 mEq/L) and can be dangerous for the heart.

Triamterene is a potassium-sparing diuretic that prevents the body from losing too much potassium in the urine. It can cause hyperkalemia (high potassium), especially in people with kidney disease, diabetes, or severe illness. The nurse should check the potassium level before giving triamterene and hold the medication if it is above 5 mEq/L.

The other choices are incorrect because:

Choice A: Sodium 142 mEq/L.

This is a normal level of sodium in the blood (the normal range is 135 to 145 mEq/L) and does not require withholding triamterene. Triamterene can cause hyponatremia (low sodium) by increasing the excretion of sodium in the urine. The nurse should monitor the sodium level during triamterene therapy and report any signs of low sodium such as confusion, weakness, or seizures.

Choice B: BUN 16 mg/dL.

This is a normal level of blood urea nitrogen (BUN) in the blood (normal range is 7 to 20 mg/dL) and does not require withholding

triamterene. BUN is a measure of kidney function and can be elevated in kidney disease or dehydration. Triamterene can cause an increase in BUN by reducing the blood flow to the kidneys or by interacting with other medications that affect the kidneys. The nurse should monitor the BUN level during triamterene therapy and report any signs of kidney impairment such as decreased urine output, swelling, or nausea. •

Choice D: Albumin 4 g/dL.

This is a normal level of albumin in the blood (the normal range is 3.4 to 5.4 g/dL) and does not require withholding triamterene. Albumin is a protein that helps maintain fluid balance and transport substances in the blood. Triamterene does not affect albumin levels directly, but it can cause fluid loss or retention that may alter albumin levels indirectly. The nurse should monitor the albumin level during triamterene therapy and report any signs of fluid imbalance such as weight changes, edema, or shortness of breath.

Correct Answer is A

Explanation

The nurse should advise the client to avoid taking St. John’s Wort with sertraline because it can increase the risk of a rare but serious condition called serotonin syndrome. Serotonin syndrome can cause symptoms such as confusion, hallucination, seizure, extreme changes in blood pressure, increased heart rate, fever, excessive sweating, shivering or shaking, blurred vision, muscle spasm or stiffness, tremor, incoordination, stomach cramp, nausea, vomiting, and diarrhoea.

Choice B. Black cohosh is wrong because it is a herbal supplement that is used to treat menopausal symptoms and has no known interaction with sertraline.

Choice C. Coenzyme Q is wrong because it is a natural substance that is involved in energy production and has no known interaction with sertraline.

Choice D. Ginger root is wrong because it is a spice that is used to treat nausea and has no known interaction with sertraline.

A. Apply pressure to the IV site. B. Elevate the extremity. C. Slow the infusion rate. D. Flush the IV catheter.

Correct Answer is B

Explanation

This will help reduce swelling and discomfort caused by the infiltration of fluid into the tissues. Elevating the extremity also promotes venous return and prevents further fluid accumulation.

Choice A is wrong because applying pressure to the IV site can increase the risk of tissue damage and infection.

Pressure can also obstruct blood flow and cause thrombophlebitis.

Choice C is wrong because slowing the infusion rate will not stop the infiltration of fluid into the tissues.

Slowing the infusion rate can also delay the delivery of medication or fluid to the client.

Choice D is wrong because flushing the IV catheter can worsen the infiltration of fluid into the tissues.

Flushing the IV catheter can also introduce air or bacteria into the bloodstream and cause complications.

Normal ranges for peripheral IV infusion are dependent on the type and volume of fluid, the size and location of the catheter, and the condition of the client. Generally, peripheral IV infusion rates should not exceed 100 mL/hr for adults and 60 mL/hr for children.
