1. What is the action of Metformin?

• A. Decreasing intestinal glucose absorption
• B. Increasing sensitivity to insulin
• C. Decreasing hepatic glucose production
• D. All of the above

Correct answer: D

Rationale: Metformin exerts its effects by decreasing hepatic glucose production, increasing sensitivity to insulin, and decreasing intestinal glucose absorption. These actions help in lowering blood glucose levels and improving insulin sensitivity in individuals with diabetes.

2. When instructing a client with a new prescription for Timolol on how to insert eye drops, which area should the nurse instruct the client to press on to prevent systemic absorption of the medication?

• A. Bony orbit
• B. Nasolacrimal duct
• C. Conjunctival sac
• D. Outer canthus

Correct answer: B

Rationale: Pressing on the nasolacrimal duct, located near the inner corner of the eye, blocks the lacrimal punctum and prevents the medication from entering the systemic circulation. This technique helps to ensure the medication stays localized in the eye, enhancing its therapeutic effect while minimizing systemic side effects. Choices A, C, and D are incorrect. The bony orbit is the eye socket and not a site to press for preventing systemic absorption. The conjunctival sac is where eye drops are instilled, not pressed on. The outer canthus is also not the correct area to press to prevent systemic absorption.

3. A healthcare provider is preparing to administer dextrose 5% in water (D5W) 750 mL IV to infuse over 6 hr. How many mL/hr should the IV pump be set to deliver?

• A. 125 mL/hr
• B. 100 mL/hr
• C. 150 mL/hr
• D. 200 mL/hr

Correct answer: A

Rationale: To calculate the flow rate, divide the total volume by the total time: (750 mL / 6 hr) = 125 mL/hr. Therefore, the IV pump should be set to deliver 125 mL/hr to infuse dextrose 5% in water (D5W) over 6 hours. Choice B, 100 mL/hr, is incorrect as it does not match the correct calculation. Choice C, 150 mL/hr, is incorrect as it is higher than the calculated flow rate. Choice D, 200 mL/hr, is incorrect as it is also higher than the calculated flow rate.

4. While collecting data from a client taking Gemfibrozil, a nurse should identify which of the following assessment findings as an adverse reaction to the medication?

• A. Mental status changes
• B. Tremor
• C. Jaundice
• D. Pneumonia

Correct answer: C

Rationale: Jaundice is an adverse reaction that the nurse should identify when assessing a client taking Gemfibrozil. It is associated with liver impairment, which can be a side effect of this medication. Mental status changes and tremors are not typically associated with Gemfibrozil use. Pneumonia is not a common adverse reaction to this medication, and its occurrence is not directly linked to Gemfibrozil use.

5. A client has a prescription for gentamicin for the treatment of an infection. Which finding indicates a potential adverse reaction to the medication?

• A. Blood pressure 160/90 mm Hg
• B. Presence of red blood cells in the urine
• C. Urine output of 35 mL/hr
• D. Respiratory rate of 22/min

Correct answer: B

Rationale: The presence of red blood cells in the urine can indicate nephrotoxicity, which is a potential adverse effect of gentamicin. Gentamicin can cause damage to the kidneys, leading to the presence of red blood cells in the urine as a sign of renal impairment. Monitoring for this finding is crucial to detect and manage adverse reactions promptly. High blood pressure (Choice A) is not typically associated with gentamicin use. Low urine output (Choice C) is more suggestive of kidney injury rather than nephrotoxicity specifically related to gentamicin. Respiratory rate (Choice D) is not a common indicator of adverse reactions to gentamicin.
