A nurse is caring for a client who has urticaria following administration of an antibiotic. Which of the following medications should the nurse prepare to administer?
Diphenhydramine
Hydralazine
Naloxone
Protamine
The Correct Answer is A
A. Diphenhydramine. Urticaria (hives) is a common allergic reaction often caused by medications like antibiotics. Diphenhydramine, an antihistamine, is used to treat allergic reactions by blocking histamine receptors, reducing itching, swelling, and rash.
B. Hydralazine. This is an antihypertensive medication used to treat high blood pressure, not allergic reactions. It has no effect on histamine or allergic symptoms.
C. Naloxone. Naloxone is an opioid antagonist used to reverse opioid overdose. It does not treat allergic reactions like urticaria unless the cause is opioid-induced (which is not indicated here).
D. Protamine. Protamine is used to reverse the effects of heparin. It has no role in treating allergic reactions to antibiotics.

Correct Answer is B
Explanation
A. Calories. Significant increases in caloric intake are not necessary during the first trimester. Most women do not require additional calories until the second and third trimesters, when fetal growth accelerates.
B. Folate. Folate (or folic acid) is crucial during early pregnancy, particularly in the first trimester, to prevent neural tube defects such as spina bifida. Women are advised to increase folate intake before conception and during early pregnancy.
C. Calcium. Calcium needs increase later in pregnancy when the fetus's bone development intensifies. While important throughout pregnancy, calcium is not the most critical nutrient to increase specifically in the first trimester.
D. Protein. Protein is essential for fetal growth, but increased protein needs become more important in the second and third trimesters when fetal tissue development peaks. Early pregnancy focuses more on folate supplementation for neural development.
Correct Answer is C
Explanation
A. "You will feel your baby moving within the next month." Fetal movement, or quickening, is typically felt between 16 and 20 weeks of gestation. At 9 weeks, it is too early for the client to detect fetal movement.
B. "Hormone shifts often cause vulvar itching." Vulvar itching is not a common or expected symptom of early pregnancy and may indicate an infection, such as a yeast infection, rather than a normal hormonal change.
C. "You should consume at least 3 liters of fluid each day." Adequate hydration is essential during pregnancy to support increased blood volume, amniotic fluid, and metabolic processes. A daily intake of about 3 liters of fluid helps prevent dehydration and constipation.
D. “Headaches are expected throughout pregnancy." While headaches can occur, especially in the first trimester due to hormonal changes, persistent or severe headaches may indicate complications like preeclampsia and should not be considered a normal, ongoing expectation.
