Loretta is taking oral contraceptives and is placed on a 10-day course of an antibiotic. The nurse plans education to include:
Discontinuing the oral contraceptives while receiving the antibiotic
Calling the HP to report increased hunger or fluid retention
Using an additional method of birth control for the remainder of the menstrual cycle and the antibiotics are completed
Taking the antibiotic two (2) hours after the oral contraceptive
The Correct Answer is C
A. Discontinuing oral contraceptives during antibiotic therapy is not recommended because abrupt cessation can disrupt hormonal regulation and does not reliably reduce interaction risk. Continuing the pills maintains cycle control, even if contraceptive effectiveness may be temporarily reduced.
B. Increased hunger or fluid retention are known side effects of hormonal contraceptives related to estrogen and progesterone effects on appetite and fluid balance. These findings are not associated with antibiotic use and do not indicate a clinically significant interaction requiring provider notification.
C. Some antibiotics can reduce the effectiveness of oral contraceptives by altering intestinal flora involved in estrogen reabsorption, leading to lower circulating hormone levels. Using a backup method such as condoms during antibiotic therapy and for the remainder of the cycle reduces the risk of unintended pregnancy.
D. Separating the timing of antibiotic and oral contraceptive doses does not prevent the interaction because the effect is related to hormone metabolism and enterohepatic circulation rather than direct absorption competition in the gastrointestinal tract.

Correct Answer is D
Explanation
A. Initiate an intravenous line: Establishing IV access is important for administering medications or fluids, but immediate oxygenation takes priority to prevent hypoxia and tissue damage in a suspected pulmonary embolism.
B. Assess the client's blood pressure: Monitoring vital signs, including blood pressure, is essential for detecting hemodynamic instability, but it is secondary to ensuring adequate oxygenation in the acute phase of a pulmonary embolism.
C. Prepare to administer Morphine sulfate: Morphine may relieve pain and anxiety, but it does not address the primary threat of hypoxemia or impaired oxygen delivery, making it a lower priority intervention.
D. Administer oxygen at 8 to 10L/min by face mask: Supplemental oxygen helps maintain adequate oxygen saturation, reduces hypoxemia, and supports vital organ perfusion. In a client with sudden dyspnea and tachycardia suggestive of a pulmonary embolism, rapid oxygen delivery is the immediate priority.
Correct Answer is B
Explanation
A. Turn the patient to semi-Fowler position: Changing maternal position can sometimes relieve cord compression, but the presence of a pulsating umbilical cord indicates umbilical cord prolapse, which is an obstetric emergency requiring immediate intervention beyond positioning.
B. Call for immediate assistance to prepare for delivery: A pulsating cord suggests cord prolapse or imminent compromise, placing the fetus at risk for hypoxia. Immediate activation of the obstetric team is the priority to expedite delivery, typically by cesarean section if vaginal birth is not imminent.
C. Oxygen at 2 L/min: Administering oxygen may support fetal oxygenation but is secondary to urgent delivery. Oxygen alone cannot resolve cord compression or prevent fetal compromise.
D. Placement of a Foley catheter: Bladder emptying may help facilitate cesarean delivery, but it is not the initial priority. The urgent focus is on activating the team and preparing for immediate delivery to prevent fetal hypoxia.
