A 28-year-old patient has been prescribed penicillin for the first time. What nursing diagnosis would be most appropriate for this patient? A. Acute pain related to gastrointestinal (GI) effects of the drug B. Deficient knowledge regarding drug therapy C. Imbalance nutrition: less than body requirements related to multiple GI effects of the drug D. Constipation - ✔️ B. Because this is the first time the patient has taken penicillin, she is likely to have limited knowledge about the drug. She may not understand the importance of taking the medication as ordered to increase effectiveness of the drug or to report adverse effects. because the patient has not started the drug yet, there is no way to know what adverse effects, if any, she will experience. Only if she develops acute pain related to GI effects of the drug would this be appropriate. If GI symptoms develop it may lead to imbalanced nutrition, but that remains to be seen. No indication about constipation exists.
he mother of a 5-year-old asks the nurse why it seems amoxicillin is always prescribed when her child needs an antibiotic. What is the priority rationale the nurse should give the mother? A) It is better absorbed. B) It is less costly. C) It has a less frequent dosing schedule. D) It tastes better in oral form. - ✔️ Ans: A Feedback: Most penicillins are rapidly absorbed from the GI tract, reaching peak levels in 1 hour. Although amoxicillin is less expensive, that fact has far less impact on choosing the proper antibiotic than the effectiveness of the drug. Most oral antibiotics for children are available in pleasant tasting syrups so taste would not be a factor. Ampicillin is often given up to 4 times a day so it actually has a frequent dosing schedule.
C) Yeast infections are unlikely to occur with this medication because it is narrow spectrum. D) Appearance of a rash is common and does not indicate an allergic reaction. - ✔️ Ans: A Feedback: One of the adverse effects of ampicillin is blackening of the tongue but the discoloration goes away after stopping the drug. If it is accompanied by swelling, the patient should be instructed to call the prescribing health care provider immediately. Many penicillin-resistant pathogens exist, so if the infection does not seem to be responding to the drug, the patient should notify the health care provider because a different antibiotic may be required. Yeast infections are very likely after taking ampicillin because it is a broad-spectrum antibiotic. Appearance of a rash should be evaluated by a health care professional because allergic reactions to this class of antibiotic are very common.
A local bioterrorism medical team is learning about germ warfare. The team is instructed that a fluoroquinolone may be used to prevent an outbreak of anthrax infection. What fluoroquinolone would the nurse be most likely to administer for this purpose? A) Ciprofloxacin (Cipro) B) Gemifloxacin (Factive) C) Norfloxacin (Noroxin) D) Sparfloxacin (Zagam) - ✔️ Ans: A Feedback: Ciprofloxacin (Cipro) is the most widely used fluoroquinolone and is indicated for the prevention of anthrax infection. Gemifloxacin and sparfloxacin are most useful in treating acute episodes of chronic bronchitis and community-acquired pneumonia. Norfloxacin is recommended only for certain types of urinary tract infections.
The nurse is providing patient teaching before discharging a patient home. The patient is taking ciprofloxacin (Cipro). What would the nurse teach this patient is the best way to prevent crystalluria caused by ciprofloxacin (Cipro)? A. Eliminate red meat and seafood from the diet. B. Encourage at least 2 liters of fluid per day. C. Avoid caffeine and alcohol. D. Spend time in the sun each day to optimize vitamin D levels. - ✔️ B. Encourage at least 2 L of fluid per day Provide the following patient teaching: Avoid driving or operating dangerous machinery because dizziness, lethargy, and ataxia may occur; try to drink a lot of fluids and maintain nutrition (very important), even though nausea, vomiting, and diarrhea may occur. There is no need to eliminate red meat, seafood, caffeine, or alcohol from the diet, although alcohol may increase the risk of GI irritation. Patients should be taught to avoid the sun due to possible photosensitivity.
The nurse would question whether the child was ever given tetracycline because this drug is commonly associated with discoloration of secondary teeth when it is administered to children who still have their primary teeth.

The clinic nurse is providing health teaching to a patient who has been prescribed doxycycline (Doxycin). What is a priority teaching point for this patient? A) Stay out of the sun. B) Avoid sexual activity. C) Take an antacid with the drug if nausea occurs. D) Chew the tablets completely before swallowing. - ✔️ ANS: A
Encourage the patient to apply sunscreen and wear protective clothing if sun exposure cannot be avoided to protect exposed skin from rashes and sunburn associated with photosensitivity reactions. If the patient is a woman the nurse may advise the patient to use barrier methods of contraceptives (if she is taking oral contraceptives) due to the drugdrug interaction but the patient would not be told to avoid sexual activity. Antacid therapy and chewing the tablets would be inaccurate information.
