The child with CF is prescribed vitamin A supplements. Which finding by the clinic nurse indicates that the vitamin has been effective?
- A. Skin is supple and healthy.
- B. Viscosity of secretions is decreased.
- C. Number of bleeding episodes is reduced.
- D. Pancreatic enzyme absorption is increased.
Correct Answer: A
Rationale: A: A water-miscible form of vitamin A is given in children diagnosed with CF because the uptake of the fat-soluble vitamins is decreased. One of the functions of vitamin A is to keep epithelial tissue healthy by aiding the differentiation of specialty cells. B: Other treatments for CF, such as bronchodilators and recombinant human deoxyribonuclease dornase alfa (Pulmozyme), decrease the viscosity of secretions. C: Vitamin K, another fat-soluble vitamin administered in CF, increases coagulation. D: Vitamin A has no effect on pancreatic enzyme absorption.

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?
- A. I am having a regular menstrual cycle now.
- B. That bad odor from my vagina is now gone.
- C. All those sores on my labia are getting better.
- D. I don't have that green vaginal discharge anymore.
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.

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?
- A. 830
- B. 1000
- C. 1230
- D. 1730
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.
