1. A client with schizophrenia is prescribed risperidone. Which statement by the client indicates the need for further teaching?
- A. I can stop taking this medication once I feel better.
- B. This medication may cause drowsiness.
- C. This medication might make me feel drowsy.
- D. I should avoid alcohol while taking this medication.
Correct answer: A
Rationale: Clients should not stop taking risperidone abruptly once they feel better without consulting their healthcare provider.
2. A client has been diagnosed with open-angle glaucoma. The healthcare provider prescribes pilocarpine 1% eye drops. The nurse explains that which action of this drug makes it a useful treatment for the client's condition?
- A. The ciliary muscle contracts, increasing the outflow of aqueous humor in the eye.
- B. Ciliary muscles are paralyzed to decrease accommodation.
- C. Bilateral mydriasis with cycloplegia is accomplished.
- D. The production of aqueous humor in the eyes is decreased.
Correct answer: A
Rationale: Pilocarpine, a cholinergic agent, stimulates the ciliary muscle to contract, which opens the trabecular meshwork and facilitates the outflow of aqueous humor, reducing intraocular pressure. This mechanism helps in managing open-angle glaucoma by improving drainage and lowering pressure within the eye. Choice A is correct because the contraction of the ciliary muscle increases the outflow of aqueous humor, aiding in the treatment of open-angle glaucoma. Choices B, C, and D are incorrect because they do not describe the mechanism of action of pilocarpine in treating glaucoma.
3. When should a client receiving insulin lispro administer this medication?
- A. Before meals
- B. After meals
- C. At bedtime
- D. Before sleep
Correct answer: A
Rationale: Insulin lispro is a rapid-acting insulin that should be administered shortly before meals. This timing helps to synchronize the peak action of insulin with the rise in blood glucose levels after eating, effectively managing blood glucose levels in the body.
4. The practical nurse (PN) is obtaining the medical history of a client starting a new prescription for conjugated estrogens PO daily. Which medical condition is not treated by this medication?
- A. Menopausal symptoms
- B. Prostatic cancer
- C. Thromboembolic diseases
- D. Abnormal uterine bleeding
Correct answer: C
Rationale: Conjugated estrogens, such as Premarin, are not used in the treatment of thromboembolic diseases. These medications are contraindicated in conditions predisposing to thromboembolic diseases due to their association with an increased risk of thromboembolism, stroke, pulmonary embolism, and myocardial infarction. Choices A, B, and D are incorrect because conjugated estrogens are commonly prescribed for managing menopausal symptoms, abnormal uterine bleeding, and certain hormone-responsive cancers, but not for thromboembolic diseases.
5. Escitalopram is prescribed for a 16-year-old adolescent client who is clinically depressed. Five days later, the parent tells the practical nurse (PN) that the drug is not working because their child is not feeling any better. Which explanation should the PN provide?
- A. It takes 1 to 4 weeks for antidepressant medications to become effective.
- B. The dosage may need to be increased; I will contact your health care provider.
- C. Depression is difficult to treat with drugs alone. Therapy sessions would enhance their effectiveness.
- D. Based on your child's response to this drug, the health care provider is reviewing your medication regimen.
Correct answer: A
Rationale: Antidepressant medications typically require 1 to 4 weeks to reach their full therapeutic effect. It is crucial to educate the family that during the initial week of treatment, the child may experience heightened anxiety. Therefore, it is important to wait for the medication to take its full course before assessing its effectiveness.
