NURS 6521 Week 1 Quiz 3.Q&A • Question 1 1 out of 1 points Tylenol 325 mg/tablet, patient needs 650 mg; how many tables should patient take? • Question 2 0 out of 1 points During a clinic visit, a patient complains of having frequent muscle cramps in her legs. The nurse's assessment reveals that the patient has been taking over-the-counter laxatives for the past 7 years. The nurse informed the patient that prolonged use of laxatives Response Feedback: Long-term intake of laxatives, antidepressants, and antibiotics has been found to deprive a person of most essential nutrients, such as vitamins. Prolonged use of laxatives is not known to turn urine acidic, cause urinary tract infections, counter the effect of other drugs, or inhibit the biotransformation of drugs. • Question 3 1 out of 1 points A 60-year-old African-American man lives with a number of chronic health problems. Genetic factors are likely to influence his etiology and/or treatment of Response Feedback: The incidence of hypertension is significantly higher among African-Americans than other ethnic groups. As well, African Americans respond to some antihypertensive drugs differently than whites. • Question 4 1 out of 1 points In response to a patient's nausea, the nurse has mixed a dose of an antiemetic with 50 mL of sterile normal saline and will administer the dose by IV piggyback. What is the rationale for the use of IV piggyback? Response Feedback: When the patient receives continuous IV fluids and is also receiving intermittent IV drug therapy, the drug is normally given through a secondary IV tubing. When a secondary IV tubing is used to administer an IV drug, the tubing is added to the main line tubing, usually at a Y port. Adding secondary tubing is called “piggybacking” because the tubing with the drug rides on top of the primary fluid tubing. Failure to adhere to a prescribed regimen, unstable electrolyte levels, and need for continuous monitoring are not rationales for the use of an IV piggyback. • Question 5 1 out of 1 points In light of her recent high blood pressure readings, a patient has been started on a thiazide diuretic and metoprolol (Lopressor), which is a beta-adrenergic blocker. What is the most likely rationale for using two medications to address the patient's hypertension? Response Feedback: A synergistic effect occurs when two or more “unlike” drugs (in terms of therapeutic effect or mechanism of action) are used together to produce a combined effect, and the outcome is a drug effect greater than either drug's activity alone. As a result, the patient's hypertension may be better treated than with a single drug. This does not necessarily reduce the risk of adverse reactions or increase compliance with the regimen. • Question 6 1 out of 1 points A patient with a variety of chronic health problems is being seen by her nurse practitioner, who is currently reviewing the patient's medication regimen. Which of the patient's medications should prompt the nurse to teach her to avoid drinking grapefruit juice? Response Feedback: Metabolism of many varied drugs such as calcium channel blockers (used to treat hypertension), statins (used to lower blood lipid levels), and antihistamines (used to prevent allergic reactions) is affected by grapefruit juice. • Question 7 1 out of 1 points A patient has been prescribed several drugs and fluids to be given intravenously. Before the nurse starts the intravenous administration, a priority assessment of the patient will be to note the Response Feedback: Baseline body weight and height, heart rate, and blood pressure are all important considerations during the assessment of a patient. However, if a patient has to be given drugs intravenously, it is important to inspect the skin for rashes, moles, or sores, so those areas can be avoided as an insertion or injection site. • Question 8 1 out of 1 points A patient has been prescribed 1 mg lorazepam (Ativan) sublingual prior to the scheduled insertion of a peripherally inserted central (PIC) line. How should the nurse direct the patient when administering this medication? Response Feedback: Sublingual tablets are placed under the tongue where they dissolve and are absorbed into the bloodstream. Swallowing the pill may render it less effective, but is not unsafe. It is not recommended to chew and hold sublingual medications nor to hold them in the mouth for length of time. ...........CONTINUED
