A client is scheduled for a spiral computed topography (CT) scan with contrast to evaluate for pulmonary embolism. Which information in the client’s history requires follow-up by the nurse?
CT scan that was performed 6 months earlier.
Takes metformin hydrochloride for type 2 diabetes.
Metal hip prosthesis was placed two years ago.
Report on client’s sobriety for the last five years.
The Correct Answer is B
Metformin is a medication that can affect kidney function. Since contrast dye used in CT scans is processed through the kidneys, it is important for the nurse to follow up on the client’s use of metformin before the CT scan with contrast. The client may need to temporarily stop taking metformin before and after the procedure to prevent any potential harm to their kidneys.

Correct Answer is D
Explanation
The client is experiencing syncope (fainting) due to a drop in blood pressure to 70/40 mm Hg, which is too low. This suggests that the client's blood pressure medications are reducing their blood pressure too much, resulting in hypotension. The rationale for the nurse's decision to hold the client's scheduled antihypertensive medications is to prevent further hypotension and allow the client's blood pressure to stabilize at a safer level.
Option a is incorrect because diuresis (increased urine output) is not a likely cause of the client's hypotension.
Option b is incorrect because the client's symptoms suggest hypotension due to reduced blood pressure, rather than drug toxicity.
Option c is incorrect because the antagonistic interaction among blood pressure medications would result in reduced effectiveness but would not necessarily cause hypotension.
Correct Answer is A
Explanation
Gentamicin sulfate is an aminoglycoside antibiotic that can cause ototoxicity, which is damage to the inner ear leading to hearing loss or balance problems. Therefore, a decrease in hearing is an indication that the client may be experiencing an adverse effect of gentamicin.
Option b, decreased blood urea nitrogen, is not an adverse effect of gentamicin, but it may indicate improvement in kidney function, which can be a positive outcome of treatment.
Option c, a white blood cell count of 6,000/mm3 (6x109/L), is within the normal range and is not necessarily an adverse effect of gentamicin.
Option d, photophobia, is not a common adverse effect of gentamicin and may indicate a different condition or medication effect.
