A nurse is preparing to administer digoxin 1.5 mg PO to a client. The amount available is digoxin 0.5 mg tablet. How many tablets should the nurse administer?

(Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Choice A reason: Asthma

Diphenhydramine is an antihistamine that can cause drying of the airways and thickening of bronchial secretions, which might exacerbate asthma symptoms. However, it is not strictly contraindicated in asthma patients. Instead, caution is advised, and it should be used under medical supervision if necessary.

Choice B reason: Hypertension

While diphenhydramine can cause mild increases in blood pressure due to its anticholinergic effects, it is not contraindicated in patients with hypertension. Patients with hypertension should use it cautiously and under medical advice, but it is not an absolute contraindication.

Choice C reason: Glaucoma

Diphenhydramine is contraindicated in patients with glaucoma, particularly closed-angle glaucoma. This is because diphenhydramine has anticholinergic properties that can increase intraocular pressure, potentially worsening the condition. Patients with glaucoma should avoid using diphenhydramine to prevent complications related to increased eye pressure.

Choice D reason: Depression

Diphenhydramine is not contraindicated in patients with depression. However, it can cause drowsiness and sedation, which might affect mood and energy levels. Patients with depression should use it cautiously and under medical supervision, but it is not an absolute contraindication.

Choice A Reason:

When calculating the fluid balance for a client undergoing continuous bladder irrigation (CBI), the irrigation solution must be deducted from the total urine output. This is because the irrigation fluid is not part of the client’s actual urine production but is an additional fluid introduced into the bladder to prevent or remove blood clots and ensure catheter patency. By deducting the irrigation solution from the total urine output, the nurse can accurately determine the client’s true urine output and fluid balance.

Choice B Reason:

Subtracting the irrigation solution from the intravenous flow sheet as output is incorrect. The intravenous flow sheet is used to document fluids administered intravenously, not those introduced into the bladder. Therefore, this choice does not apply to the management of continuous bladder irrigation.

Choice C Reason:

Documenting the intake hourly in the urine output column is also incorrect. The urine output column should reflect the actual urine produced by the client, not the irrigation solution. Including the irrigation solution in this column would lead to an inaccurate representation of the client’s urine output and fluid balance.

Choice D Reason:

Adding the irrigation solution to the oral intake column is incorrect as well. The oral intake column is designated for fluids consumed orally by the client. The irrigation solution is introduced directly into the bladder and should not be recorded as oral intake.
