Question 1 of 5
A nurse is preparing to administer methylergonovine IM for a client who had a vaginal delivery earlier that day. The nurse should explain to the client that this medication will help prevent which of the following?
Correct Answer: C
Rationale: The correct answer is C: Postpartum hemorrhage. Methylergonovine is a uterotonic medication used to prevent or manage postpartum hemorrhage by promoting uterine contractions and reducing the risk of excessive bleeding. It helps the uterus to contract and close off blood vessels, which can prevent excessive bleeding after delivery.
Incorrect choices:
A: Postpartum infection - Methylergonovine does not prevent postpartum infection; it is specifically indicated for preventing hemorrhage.
B: Hypertension - Methylergonovine may cause hypertension as a side effect, but it is not its primary purpose.
D: Thromboembolic events - Methylergonovine does not prevent thromboembolic events; it works on the uterus to prevent hemorrhage.
Question 2 of 5
A nurse is assisting with the preparation of an educational program about the use of oral contraceptives. The nurse should include that which of the following herbal supplements reduces the effectiveness of oral contraceptives?
Correct Answer: B
Rationale: The correct answer is B: St. John's wort. St. John's wort is known to induce drug-metabolizing enzymes, potentially reducing the effectiveness of oral contraceptives. It can decrease the blood levels of estrogen and progesterone, making the contraceptives less effective. Ginger root (
A), Gingko biloba (
C), and Glucosamine (
D) do not have known interactions with oral contraceptives. St. John's wort is the only choice that directly impacts the effectiveness of oral contraceptives.
Question 3 of 5
A nurse is reinforcing teaching with a client who has a prescription for lithium carbonate to treat bipolar disorder. Which of the following instructions should the nurse include?
Correct Answer: B
Rationale: The correct answer is B: Wait up to 3 weeks to see the full effects of the medication. This is because lithium carbonate, commonly used to treat bipolar disorder, takes time to reach therapeutic levels in the blood and for the client to experience the full benefits of the medication. It is important for the nurse to educate the client about this delayed onset of action to manage expectations and encourage adherence to the treatment plan.
A: Taking the medication on an empty stomach is not necessary for lithium carbonate.
C: Following a low-sodium diet is important to monitor for potential side effects, but it is not the most crucial instruction to include.
D: Limiting fluid intake to 800 ounces per day is excessive and could lead to dehydration, so this instruction is incorrect.
E, F, G: No additional options provided.
Question 4 of 5
A nurse is collecting data from client who has just begun therapy with alprazolam to treat anxiety. The nurse should observe the client for which of the following adverse effects of this medication?
Correct Answer: C
Rationale: The correct answer is C: Sedation. Alprazolam is a benzodiazepine commonly used to treat anxiety. Sedation is a common adverse effect of benzodiazepines due to their central nervous system depressant properties. This medication can cause drowsiness, fatigue, and impaired coordination. Monitoring for sedation is important to ensure the client's safety and to adjust the dosage if needed.
Choice A: Hypertension is not a common adverse effect of alprazolam. It is more likely to cause hypotension.
Choice B: Hearing loss is not a typical adverse effect of alprazolam.
Choice D: Bradycardia is not a common adverse effect of alprazolam. It is more likely to cause tachycardia as a side effect.

Correct Answer: C
Rationale: The correct answer is C. Yellow emesis is a common adverse effect of oral erythromycin due to its irritation of the gastrointestinal tract, leading to nausea and vomiting. This occurs because erythromycin stimulates gastrointestinal motility. A: Ringing in the ears is not a common adverse effect of erythromycin. B: Constipation with abdominal cramping is not a common adverse effect of erythromycin; rather, it can cause gastrointestinal upset. D: Swollen lips are not a common adverse effect of erythromycin; this may indicate an allergic reaction.
