1. A client has a prescription for Timolol eye drops for the treatment of glaucoma. Which of the following instructions should the nurse include?

A. Apply gentle pressure to the nasolacrimal duct for 30 to 60 seconds after application.
B. Avoid blinking immediately after instilling the drops.
C. Keep your eyes closed for 5 minutes after application.
D. Administer the drops directly onto the cornea.

Correct answer: A

Rationale: The correct instruction for the nurse to include is to apply gentle pressure to the nasolacrimal duct for 30 to 60 seconds after application. This technique helps prevent systemic absorption of the medication, reducing the risk of systemic side effects. By applying pressure, the drainage of the medication into the bloodstream through the nasolacrimal duct is minimized, enhancing the drug's local ocular effects. Choices B, C, and D are incorrect because blinking immediately after instilling the drops, keeping eyes closed for 5 minutes, and administering the drops directly onto the cornea are not recommended practices for administering Timolol eye drops.

2. Which of the following is not an effect of the drug isoflurane?

A. Elevated lipid levels
B. Nausea
C. Increased blood flow to the brain
D. Decreased respiratory function

Correct answer: A

Rationale: Isoflurane is not known to cause elevated lipid levels. Common effects of isoflurane include nausea, increased blood flow to the brain, and decreased respiratory function. Elevated lipid levels are not typically associated with the administration of isoflurane, making choice A the correct answer.

3. A client has a new prescription for Atenolol. Which of the following instructions should the nurse provide?

A. Take this medication with grapefruit juice.
B. Monitor your blood pressure and heart rate regularly.
C. You may experience a rapid heart rate.
D. Increase your intake of potassium-rich foods.

Correct answer: B

Rationale: The correct answer is B: 'Monitor your blood pressure and heart rate regularly.' Atenolol is a beta-blocker used to treat hypertension and other cardiovascular conditions. Patients should monitor their blood pressure and heart rate regularly to assess the medication's effectiveness and check for adverse effects like bradycardia or hypotension. Choice A is incorrect because Atenolol should not be taken with grapefruit juice, which can interfere with its absorption. Choice C is incorrect because Atenolol typically causes a decrease in heart rate, not a rapid heart rate. Choice D is incorrect because there is no specific need to increase potassium-rich foods while taking Atenolol.

4. What is the classification for the drug valproate?

A. Anti-diabetic
B. Anti-convulsant
C. Anti-ulcer agent
D. Anti-hypertensive

Correct answer: B

Rationale: Valproate is classified as an anticonvulsant. It is commonly used to treat epilepsy and bipolar disorder by stabilizing electrical activity in the brain. Therefore, the correct classification for valproate is as an anticonvulsant. Options A, C, and D are incorrect because valproate is not used to treat diabetes, ulcers, or hypertension.

5. A healthcare professional is reviewing a client's medication history and notes a new prescription for Enalapril. The healthcare professional should monitor the client for which of the following as an adverse effect of this medication?

A. Bradycardia
B. Hyperkalemia
C. Hypoglycemia
D. Hypocalcemia

Correct answer: B

Rationale: Enalapril, an ACE inhibitor, can cause hyperkalemia as an adverse effect due to decreased aldosterone levels, which leads to potassium retention. Monitoring potassium levels is essential to prevent potential complications associated with hyperkalemia. The other options, bradycardia, hypoglycemia, and hypocalcemia, are not typically associated with Enalapril use and are less likely to occur as adverse effects.
