Extract:
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 reinforcing teaching with a client who takes lithium carbonate for bipolar disorder. For which of the following findings should the nurse monitor as an adverse effect of lithium carbonate?
Correct Answer: A
Rationale: The correct answer is A: Thyroid enlargement. Lithium carbonate can lead to hypothyroidism, causing thyroid enlargement. The nurse should monitor for signs such as weight gain, fatigue, and cold intolerance.
Choice B, constipation, is not a common adverse effect of lithium.
Choice C, hyporeflexia, is not typically associated with lithium use.
Choice D, elevated blood pressure, is more commonly seen with other medications used for bipolar disorder.
Question 3 of 5
A nurse is collecting data from a client who takes several daily medications and states that he wants to ask the provider for a prescription for sildenafil. The nurse knows that sildenafil is contraindicated due to an interaction with which of the following client's medications?
Correct Answer: C
Rationale: The correct answer is C: Isosorbide. Sildenafil is contraindicated with nitrates like isosorbide due to the risk of severe hypotension. Nitrates and sildenafil both cause vasodilation, leading to a significant drop in blood pressure when taken together.
Choices A, B, and D do not have significant interactions with sildenafil.
Choice E, F, and G are irrelevant.
Question 4 of 5
A nurse is caring for a client who has schizophrenia and is receiving clozapine. For which of the following findings should the nurse monitor to determine if the medication is having a therapeutic effect?
Correct Answer: A
Rationale: The correct answer is A: Decreased auditory hallucinations. Clozapine is an antipsychotic medication commonly used to treat schizophrenia. Monitoring for decreased auditory hallucinations is essential to determine if the medication is effective in managing the client's psychotic symptoms. Auditory hallucinations are a prominent feature of schizophrenia, and reduction in these hallucinations indicates that the medication is helping to alleviate the positive symptoms of the disorder.
Choices B, C, and D are incorrect because control of seizure activity, weight gain, and decreased WBC count are not directly related to the therapeutic effect of clozapine in managing schizophrenia symptoms. Weight gain is a common side effect of clozapine, while monitoring for decreased WBC count is important due to the risk of agranulocytosis associated with clozapine.
Question 5 of 5
A nurse is reinforcing teaching with a client who has benign prostatic hypertrophy and has a new prescription for finasteride. Which of the following information should the nurse include in the teaching?
Correct Answer: A
Rationale: The correct answer is A: Decreased libido is an adverse effect of the medication. Finasteride is known to cause sexual side effects such as decreased libido, erectile dysfunction, and ejaculatory disorders. This information is crucial for the client to be aware of before starting the medication.
Choice B is incorrect because finasteride actually decreases PSA levels, so they would not increase while taking this medication.
Choice C is incorrect as there is no known interaction between finasteride and grapefruit juice.
Choice D is incorrect because it usually takes several months to see the full effects of finasteride on BPH symptoms, not just one week.
