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 C

Explanation

The correct answer is choice C. Keep the tablets at room temperature in their original glass bottle. Rationales: Choice A rationale: Taking one tablet each morning 30 minutes prior to eating is incorrect. Sublingual nitroglycerin is used to relieve acute angina attacks and is taken as needed rather than on a fixed schedule. Choice B rationale: Discarding any tablets not used every 6 months is incorrect. Sublingual nitroglycerin tablets should be replaced every 6 months to ensure potency, but this is not the main teaching point for safe storage. Choice C rationale: Keeping the tablets at room temperature in their original glass bottle is correct. Nitroglycerin tablets are sensitive to light and moisture, and the original glass bottle protects them from these elements, ensuring their effectiveness. Choice D rationale: Placing the tablet between the cheek and gum to dissolve is incorrect. Sublingual nitroglycerin tablets should be placed under the tongue where they dissolve and are absorbed quickly into the bloodstream for rapid relief of angina symptoms

A. Decrease in protein. B. Increase in BP. C. Oxygen saturation 96%. D. PaCO2, 30 mm Hg.

Correct Answer is B

Explanation

Albumin is a protein that helps maintain fluid balance in the body by drawing water into the blood vessels. Albumin infusion can increase the blood volume and blood pressure in patients who are in shock due to fluid loss or sepsis.

Choice A is wrong because albumin infusion does not decrease protein levels in the body.

Albumin is a protein itself and adding it to the blood increases the protein concentration.

Choice C is wrong because oxygen saturation of 96% is normal and does not indicate any improvement or deterioration in the patient’s condition.

Choice D is wrong because PaCO2 of 30 mm Hg is low and indicates respiratory alkalosis, which can be caused by hyperventilation, fever, or anxiety. Albumin infusion does not affect PaCO2 levels directly.
