Before starting antimicrobial therapy, the nurse assesses a patient for possible drug allergy. Which of the following complaints should alert the nurse to a drug allergy?
Headaches
Hives or shortness of breath
Diarrhea
Nausea
The Correct Answer is B
A. Headaches:
Headaches are a common symptom that can occur for various reasons, including stress, tension, dehydration, or as a side effect of medications. While headaches can sometimes occur as a side effect of certain drugs, they are not specific indicators of a drug allergy. Allergic reactions to medications typically involve other symptoms such as rash, hives, itching, swelling, or respiratory symptoms.
B. Hives or shortness of breath:
Hives (urticaria) are raised, red, itchy welts on the skin that can occur as an allergic reaction to medications. They are a common manifestation of drug allergies. Shortness of breath (dyspnea) can occur as part of a severe allergic reaction known as anaphylaxis. Anaphylaxis is a life-threatening allergic reaction characterized by a rapid onset of symptoms, including difficulty breathing, swelling of the throat or tongue, rapid heart rate, and low blood pressure. Both hives and shortness of breath are significant signs of a potential drug allergy and require immediate attention.
C. Diarrhea:
Diarrhea can occur as a side effect of medications, including antibiotics. However, it is not typically a specific indicator of a drug allergy. Diarrhea is more commonly associated with gastrointestinal disturbances or as a reaction to changes in gut flora due to antibiotic use.
D. Nausea:
Nausea is a common side effect of many medications, including antibiotics. While it can be bothersome, nausea alone is not a specific indicator of a drug allergy. Allergic reactions to medications typically involve other symptoms such as rash, hives, itching, swelling, or respiratory symptoms.

Correct Answer is B
Explanation
A. “It’s fine for me to become pregnant while taking this medication.”
This statement is incorrect. Tetracycline is known to have teratogenic effects, meaning it can harm the developing fetus if taken during pregnancy. Women of childbearing age should use effective contraception while taking tetracycline and avoid becoming pregnant during treatment.
B. “I will need to postpone my vacation at the beach until I finish this medication."
This statement demonstrates an understanding of the discharge instructions. Tetracycline can increase the risk of sunburn and photosensitivity reactions. Therefore, it's advisable for the client to avoid prolonged sun exposure, particularly during peak sunlight hours, and to use sun protection measures such as wearing protective clothing, using sunscreen, and avoiding tanning beds or sunlamps. Postponing a vacation at the beach until after finishing the medication is a prudent precaution to minimize the risk of sun-related side effects.
C. “I am so glad to be leaving today because I have an appointment at the tanning salon."
This statement is incorrect. Tetracycline can increase the risk of sunburn and photosensitivity reactions. Visiting a tanning salon while taking tetracycline can further increase the risk of skin damage and should be avoided.
D. "I will stop taking this medication as soon as I feel better.”
This statement is incorrect. It's important for the client to complete the full course of tetracycline as prescribed by their healthcare provider, even if they start to feel better before finishing the medication. Stopping the medication prematurely can lead to incomplete treatment and potential recurrence of the infection.
Correct Answer is ["0.6"]
Explanation
To calculate the volume of diazepam solution needed, we can use the formula:
Volume (mL) = Total dose (mg) / Concentration (mg/mL)
Given:
Total dose = 3 mg
Concentration = 5 mg/mL
Plugging the values into the formula:
Volume (mL) = 3 mg / 5 mg/mL
Volume (mL) = 0.6 mL
The nurse should administer: 0.6 mL
