The nurse will anticipate that a 61-year-old client who has an enlarged prostate detected by digital rectal exam (DRE) and an elevated prostate specific antigen (PSA) level will need teaching about
magnetic resonance imaging (MRI)
uroflowmetry studies
cystourethroscopy
transrectal ultrasonography (TRUS)
The Correct Answer is D
A. Magnetic resonance imaging (MRI) may be used in some cases, but TRUS is more commonly used to guide biopsies after concerns arise from DRE or PSA findings.
B. Uroflowmetry studies measure urine flow, which is not the primary concern in evaluating an enlarged prostate related to potential cancer.
C. Cystourethroscopy is used to evaluate the bladder or urethra and is not typically needed in the assessment of an enlarged prostate.
D. Transrectal ultrasonography (TRUS) is commonly used in the evaluation of prostate abnormalities, especially when there are concerns about prostate cancer due to an abnormal DRE or elevated PSA. It helps in visualizing the prostate and guiding biopsy.

Correct Answer is B
Explanation
A. Base deficit (HCO3): Acidosis: A base deficit indicates metabolic acidosis, but respiratory acidosis is more likely with the high rate of ventilation.
B. Acid excess (CO2): Acidosis: This is the correct answer. A high respiratory rate can lead to hyperventilation, decreasing CO2 levels and causing respiratory alkalosis, which may be a concern with an elevated rate.
C. Base excess (HCO3): Alkalosis: This would indicate metabolic alkalosis, but it is not as related to ventilator settings.
D. Acid deficit (CO2): Alkalosis: If the CO2 level is too low due to hyperventilation, this can lead to alkalosis, which the nurse is questioning here.
Correct Answer is ["937.5"]
Explanation
Calculate the fluid volume to be administered in the remaining 16 hours:
Total fluid volume - Fluid administered in the first 8 hours = Remaining fluid volume
30,000 mL - (1875 mL/hr * 8 hr) = 15,000 mL
Calculate the infusion rate for the remaining 16 hours:
Remaining fluid volume / Remaining time = Infusion rate
15,000 mL / 16 hr = 937.5 mL/hr
Therefore, the nurse should infuse the IV fluids at a rate of 937.5 mL/hr after the first 8 hours.
