Question 1 of 5
The hospitalized client is prescribed to receive ferrous fumarate 200 mg oral daily. When transcribing the medication onto the client's MAR, at which time in military time should the nurse schedule the daily dose for best absorption?
Correct Answer: B
Rationale: A: 0830 is near the time of breakfast in a health care facility. Food reduces the absorption of iron. B: For best absorption and therapeutic effectiveness, the nurse should schedule ferrous fumarate (Feosol) at 1000. Iron preparations should be administered one hour before or two hours after a meal because food diminishes iron absorption. C: 1230 is near lunchtime in a health care facility. Food reduces the absorption of iron. D: 1730 is near the evening meal in a health care facility. Food reduces the absorption of iron.
Question 2 of 5
The nurse teaches the client with relapsing-remitting MS about glatiramer. Which information addressed by the client indicates that the nurse's teaching has been effective? Select all that apply.
Correct Answer: A,B,C
Rationale: A: Glatiramer is used to delay the progression of MS.
To maximize the therapeutic effects of glatiramer, it should be refrigerated and reconstituted correctly. B: Glatiramer is only administered subcutaneously; accidental IV administration must be avoided. C: Injection sites are rotated to prevent skin breakdown or lumps at the injection sites. D: Appropriate subcutaneous injection sites for glatiramer include the thigh, back of the hip, abdomen, and upper arm. E: Used syringes should be placed in a puncture-resistant container for proper disposal. Syringes and needles should not be reused.
Question 3 of 5
The 16-year-old is taking acyclovir. Which statement, if made by the adolescent, should indicate to the nurse that the medication is having the desired therapeutic effect?
Correct Answer: C
Rationale: A: A side effect of acyclovir is a change in the menstrual cycle; however, having a regular menstrual cycle is not the desired therapeutic effect. B: A bad odor from the vagina is a symptom of bacterial vaginosis or trichomoniasis vaginalis, and usually not a symptom of genital herpes simplex. C: Acyclovir (Zovirax), an antiviral medication, is indicated for the treatment of genital herpes simplex virus, shingles, or chicken pox. Labial sores are associated with genital herpes simplex. Improvement of labial sores indicates that acyclovir is having the desired therapeutic effect. D: A green vaginal discharge may be a symptom of Trichomonas, which is treated with metronidazole (Flagyl), an amebicide.
Question 4 of 5
The 40-year-old client is receiving levothyroxine for treatment of hypothyroidism. Which serum laboratory results should lead the nurse to conclude that the client's dose is adequate?
Correct Answer: B
Rationale: A: Cortisol levels are used to evaluate adrenal and not thyroid function. B: Restoration of normal laboratory values for TSH and free T4 indicates that the dose of levothyroxine (Synthroid) is therapeutic. C: T3 is used to evaluate the effectiveness of liothyronine and propylthiouracil, used in the treatment of thyroid disorders. D: The WBC count is used to determine if the client has an infection. Evaluation of serum glucose and potassium levels is unrelated to the use of levothyroxine.
Question 5 of 5
The HCP prescribes a second antihypertensive medication for the client who has poorly controlled BP on one medication. If prescribed, which medication combination should the nurse question?
Correct Answer: A
Rationale: A: The nurse should question this medication combination. When two medications are used to treat hypertension, each should be from different drug classifications. Atenolol (Tenormin) and metoprolol (Lopressor) are both beta-adrenergic blockers and have the same general mechanism of action. B: Metolazone (Zaroxolyn) is a thiazide-like diuretic, and valsartan (Diovan) is an ARB. C: Captopril (Capoten) is an ACE inhibitor, and furosemide (Lasix) is a loop diuretic. D: Bumetanide (Bumex) is a loop diuretic, and diltiazem (Cardizem) is a calcium channel blocker.
