Nursing Elites

1. 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.

2. A client with a diagnosis of generalized anxiety disorder is prescribed lorazepam. The client should be informed that this medication may have which potential side effect?

• A. Drowsiness
• B. Dry mouth
• C. Nausea
• D. Headache

Correct answer: A

Rationale: The correct answer is A: Drowsiness. Lorazepam, a medication commonly used to treat anxiety disorders, can lead to drowsiness as a common side effect. It is important for clients to be aware of this potential effect, and they should be advised to avoid activities like driving until they understand how the medication affects them. Dry mouth, nausea, and headache are possible side effects of other medications but are less commonly associated with lorazepam.

3. A client who is obtunded arrives in the emergency center with a suspected drug overdose. Intravenous naloxone is given, but within a short period, the client's level of consciousness deteriorates. What action should the nurse take first?

• A. Initiate a second intravenous access site
• B. Prepare to initiate cardiopulmonary resuscitation
• C. Determine the results of the drug toxicity screen
• D. Administer an additional dose of naloxone

Correct answer: D

Rationale: Administering an additional dose of naloxone should be the first action taken by the nurse in this scenario. Naloxone is an opioid antagonist used to reverse the effects of opioid overdose. If the client's level of consciousness deteriorates after the initial dose, administering another dose can help further reverse the overdose effects and improve the client's condition. Once the additional naloxone dose is given, the nurse can then proceed to assess the client's response and consider other interventions as needed.

4. A client who received a prescription for cyclosporine ophthalmic emulsion for dry eyes asks the practical nurse (PN) if it is safe to continue using artificial tears. What information should the PN provide?

• A. Avoid using artificial tears because they decrease the efficacy of cyclosporine.
• B. Discontinue the use of both products if transient blurring occurs after administration.
• C. Allow a 15-minute interval between the administration of cyclosporine and artificial tears.
• D. Discontinue the use of cyclosporine and artificial tears when tear production reaches a normal level.

Correct answer: C

Rationale: The correct answer is to allow a 15-minute interval between the administration of cyclosporine and artificial tears. Cyclosporine, an ophthalmic emulsion that increases tear production, can be used in conjunction with artificial tears as long as the products are administered 15 minutes apart. This interval helps to prevent any potential interactions between the two products and ensures optimal effectiveness of cyclosporine for treating dry eyes.

5. A client with diabetes mellitus is prescribed insulin glargine. What information should the practical nurse (PN) provide to the client about this medication?

• A. Administer the insulin at mealtimes.
• B. Do not mix this insulin with other insulins.
• C. Shake the vial well before use.
• D. Store the insulin in the freezer.

Correct answer: B

Rationale: Insulin glargine is a long-acting insulin that should not be mixed with other insulins in the same syringe. Mixing it with other insulins can alter its pharmacokinetics and effectiveness. Insulin glargine is usually administered at the same time each day, often at bedtime, to provide a consistent basal level of insulin over 24 hours.
