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.
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 D
Explanation
The correct answer is d. Administer the medication over 2 hr.
Choice A reason: Discarding the medication if it is yellow is not necessary. The color of amphotericin B lipid complex does not indicate its effectiveness or safety.
Choice B reason: Using a gravity flow set is not specifically required for the administration of amphotericin B lipid complex. Gravity infusion can be used to administer fluids and drugs where the rate is not critical and serious adverse effects are not anticipated. However, the use of a gravity flow set is not specifically mentioned in the guidelines for administering amphotericin B lipid complex.
Choice C reason: Priming the tubing with 0.9% sodium chloride is not recommended for amphotericin B lipid complex. This is because amphotericin B lipid complex is incompatible with saline solutions and should be diluted only with 5% dextrose injection. Priming the tubing is a common practice in IV therapy to remove air from the tubing before attaching it to the patient.
Choice D reason: Administering the medication over 2 hr is the correct action. Amphotericin B lipid complex is typically administered over a longer period, often 2-6 hours. This allows for a slow and steady delivery of the medication, which can help to minimize potential side effects.
Correct Answer is B
Explanation
This is the recommended dosage for cyanocobalamin nasal spray for pernicious anaemia and vitamin B12 deficiency. Cyanocobalamin nasal gel is used to prevent a lack of vitamin B12 that may be caused by various factors.
Choice A is wrong because the duration of treatment depends on the individual’s response and blood levels of vitaminB. Some people may need to use this medication for longer than 6 months.
Choice C is wrong because there is no need to lie down for 1 hour after administering the medication.
This may cause nasal irritation or drainage.
Choice D is wrong because using a nasal decongestant 15 minutes before the medication may interfere with the absorption of cyanocobalamin. If you have a stuffy nose, you should talk to your doctor about alternative ways to take vitaminB.
