A nurse is teaching a client who has benign prostatic hypertrophy and has a new prescription for finasteride. Which of the following instructions should the nurse include in the teaching?
Expect to see a response from the medication within one week.
Women should avoid touching this medication.
PSA levels will increase while taking this medication.
Avoid drinking grapefruit juice when taking this medication.
The Correct Answer is B
Choice A reason: This is incorrect because the patient may not see a response from the medication for at least six months. The patient should continue taking the medication as prescribed and follow up with the provider regularly.
Choice B reason: This is correct because finasteride can cause birth defects in male fetuses if it is absorbed through the skin or ingested by pregnant women. The patient should wear gloves when handling the tablets and avoid contact with crushed or broken tablets.
Choice C reason: This is incorrect because PSA levels will decrease while taking this medication. PSA stands for prostate-specific antigen, which is a marker for prostate cancer. The patient should inform the provider that they are taking finasteride before having a PSA test, as it may affect the results.
Choice D reason: This is incorrect because grapefruit juice does not interact with finasteride. However, the patient should avoid alcohol and other medications that may affect the liver while taking finasteride.

Correct Answer is C
Explanation
The correct answer is c. 2,525 mL.
Choice A reason:
1,350 mL is calculated by considering only the lactated Ringer’s IV intake. The calculation is as follows:
- Lactated Ringer’s IV at 150 mL/hr for 9 hr: 150 mL/hr × 9 hr = 1,350 mL. This option does not include the intake from cefazolin, packed RBCs, sodium chloride boluses, or famotidine.
Choice B reason:
1,600 mL is not a correct calculation based on the given intake. This value does not accurately sum up any combination of the provided intake components.
Choice C reason:
2,525 mL is the correct total intake. The detailed calculation is:
- Lactated Ringer’s IV at 150 mL/hr for 9 hr: 150 mL/hr × 9 hr = 1,350 mL.
- Cefazolin in 100 mL of 0.9% sodium chloride: 100 mL.
- Two units of packed RBCs: 275 mL + 250 mL = 525 mL.
- Two IV bolus infusions of 250 mL of 6.0% sodium chloride: 250 mL + 250 mL = 500 mL.
- Famotidine in 50 mL of 0.9% sodium chloride: 50 mL.
Adding these together: 1,350 mL + 100 mL + 525 mL + 500 mL + 50 mL = 2,525 mL.
Choice D reason:
2,100 mL is not a correct calculation based on the given intake. This value does not accurately sum up any combination of the provided intake components.
Correct Answer is D
Explanation
Choice A reason: This is incorrect because reporting symptoms that last longer than 2 days is not specific to guaifenesin. This is a general instruction for any patient with a sinus infection, regardless of the medication they are taking.
Choice B reason: This is incorrect because reporting clear-colored sputum to the prescriber is not necessary. Clear-colored sputum indicates that the infection is improving and the mucus is thinning. This is a desired effect of guaifenesin, not a problem that needs to be reported.
Choice C reason: This is incorrect because guaifenesin does not have sedating effects. Guaifenesin is an expectorant that helps to break up and expel mucus from the respiratory tract. It does not cause drowsiness or impair the ability to drive or operate machinery.
Choice D reason: This is correct because increasing fluid intake is an important instruction for a patient taking guaifenesin. Fluids help to hydrate the body and thin the mucus, making it easier to cough up and clear the sinuses. Fluids also help to prevent dehydration and dryness of the mucous membranes.
