An 18-year-old pregnant adolescent in her third trimester has dyspepsia despite previous treatment with Maalox. A safe choice for the nurse practitioner to prescribe is:
ranitidine HC (Zantac).
sodium bicarbonate.
sodium citrate and citric acid (Bicitra).
aluminum, magnesium and simethicone (Gelusil).
The Correct Answer is A
Rationale:
A. Ranitidine HCl (Zantac), a histamine-2 receptor antagonist, is considered safe for use in pregnancy for treating dyspepsia and gastroesophageal reflux, particularly when antacids alone are insufficient. It reduces gastric acid production without significant risk to the fetus.
B. Sodium bicarbonate is generally avoided in pregnancy due to the risk of systemic alkalosis and fluid overload.
C. Sodium citrate and citric acid (Bicitra) are typically used to alkalinize urine or prevent aspiration during anesthesia, not for routine dyspepsia management in pregnancy.
D. Aluminum, magnesium, and simethicone (Gelusil) are generally safe in moderation, but they are less effective than H2 blockers for persistent symptoms and may cause constipation or diarrhea depending on the formulation.

Correct Answer is D
Explanation
Rationale:
A. Hypoxia may cause some stress responses but is not the most common cause of temperature instability in a newborn.
B. Congenital heart disease can affect perfusion but typically does not directly cause temperature instability.
C. Polycythemia may affect circulation but is not a primary cause of abnormal temperature regulation.
D. Sepsis is a common cause of temperature instability in newborns, manifesting as hypothermia or hyperthermia. Newborns have immature thermoregulatory systems, and infections can easily disrupt temperature homeostasis, making temperature instability an important early sign of neonatal sepsis.
Correct Answer is B
Explanation
Rationale:
A. Headaches and breast tenderness are more commonly associated with premenstrual syndrome (PMS) rather than dysmenorrhea.
B. Nausea, vomiting, and back pain are classic findings of dysmenorrhea, which is painful menstruation often caused by increased prostaglandin production leading to uterine contractions and associated systemic symptoms.
C. Urinary frequency and burning suggest a urinary tract infection rather than menstrual pain.
D. Vaginal dryness and pruritus are signs of irritation or hormonal changes, not dysmenorrhea.
