Question 1 1 / 1 pts Men who are prescribed phosphodiesterase type 5 (PDE-5) inhibitors for erectile dysfunction should be educated regarding the adverse effects of the drug which includes the following: delayed ejaculation Correct! hearing loss hair loss hypertension Question 2 1 / 1 pts Which of the following factors influence medication adherence in pediatric patients? be the least concentrated form of the medication be administered 3 or 4 times a day have a short half-life Correct! be the best tasting of the effective drugs Question 3 1 / 1 pts In geriatric patients, the percentage of body fat is increased. What are the pharmacologic implications of this physiologic change? There are no pharmacological implications of this physiologic change. Correct! A lipid-soluble medication will accumulate in fat tissue and its duration of action may be prolonged. A lipid-soluble medication will be eliminated more quickly and not work as well. The bioavailability of the lipid-soluble drug will be increased in older adults. Question 4 1 / 1 pts Which of the following accurately describes the pharmacodynamic and pharmacokinetic changes that occur in older patients? Decreased CYP450 system function results in increased metabolic clearance of a drug. Decreased hepatic blood flow results in increased first-pass effect. Decrease renal mass results in increased renal clearance of a drug. Correct! Reduced thermoregulatory ability leads to an increased hypothermia risk. Question 5 1 / 1 pts Topical corticosteroids are prescribed cautiously in young children due to which of the following reasons? They may cause an intense hypersensitivity reaction. Corticosteroids are less effective in young children. Children absorb topical medications less readily than adults which can result in overprescribing. Correct! They may cause systemic hypothalamic-pituitary-adrenal axis suppression. Question 6 1 / 1 pts Education of parents regarding administering oral antibiotics to an infant includes which of the following? Calling for an antibiotic change if the infant chokes and sputters during administration. Correct! How to administer an oral drug using a medication syringe.

Which of the following may help in reducing them? pyridoxine (Vitamin B6) alcohol caffeine Correct! soy Question 8 1 / 1 pts When assessing a male for hypogonadism prior to prescribing testosterone replacement, serum testosterone levels should be drawn when? in the evening late afternoon Correct! first thing in the morning without regard to time of day Question 9 1 / 1 pts Which of the following is true regarding pharmacokinetic gender differences between men and women? Correct! Women have a higher proportion of body fat, which influences the volume of drug distribution. Men have higher levels of bile acids, which affect metabolism in the intestine. Women have more rapid gastric emptying times, which influences drug absorption and bioavailability. Men have lower organ blood flow rates, which influences drug excretion. Question 10 1 / 1 pts When prescribing phosphodiesterase type 5 (PDE-5) inhibitors such as sildenafil (Viagra) patients should be screened for use of which of the following? insulin diuretics statins Correct! nitrates Quiz Score: 10 out of 10
