Nursing Elites

1. What is the antidote for copper toxicity?

• A. Glucagon
• B. Aminocaproic acid
• C. Atropine
• D. Penicillamine

Correct answer: D

Rationale: Penicillamine is the specific chelating agent used for copper toxicity. It forms stable complexes with copper, which are then excreted in the urine. Glucagon is used for treating hypoglycemia, aminocaproic acid is used to treat bleeding disorders, and atropine is used as an antidote for certain types of poisoning, such as organophosphate toxicity.

2. When teaching a client with a new prescription for Timolol how to insert eye drops, which instruction should the nurse include?

• A. Press your finger on the inside corner of your eye for 1 minute after application.
• B. Apply the eye drops directly on the cornea.
• C. Drop the prescribed amount of medication into the center of the conjunctival sac.
• D. Wipe your eyes gently with a tissue immediately after application.

Correct answer: C

Rationale: The correct way to administer eye drops is by instructing the client to drop the prescribed amount of medication into the center of the conjunctival sac. This technique helps in proper distribution and absorption of the medication. Choice A is incorrect as pressing the inside corner of the eye is not necessary. Choice B is incorrect because applying eye drops directly on the cornea can cause irritation and discomfort. Choice D is incorrect as wiping the eyes immediately after application can remove the medication and reduce its effectiveness.

3. A client is prescribed furosemide. Which of the following instructions should the nurse include in the teaching?

• A. Take this medication in the morning.
• B. Avoid eating foods high in potassium.
• C. You should take this medication on an empty stomach.
• D. Limit your fluid intake to 1 liter per day.

Correct answer: A

Rationale: The correct instruction for a client prescribed furosemide is to take the medication in the morning. Furosemide, a diuretic, is best taken in the morning to prevent nocturia, which is excessive urination at night. Taking it earlier in the day can help reduce disruptions to sleep patterns. Therefore, advising the client to take furosemide in the morning is crucial for optimal therapeutic effects. Choices B, C, and D are incorrect because furosemide does not require avoiding potassium-rich foods, does not need to be taken on an empty stomach, and does not mandate limiting fluid intake to 1 liter per day.

4. How do ACE inhibitors work?

• A. Block the vasoconstrictor and aldosterone effects of angiotensin II at the receptor site
• B. Block stimulation of beta 1 and beta 2 at the receptor sites
• C. Block the conversion of angiotensin I to the vasoconstrictor angiotensin II
• D. None of the above

Correct answer: C

Rationale: ACE inhibitors work by inhibiting the conversion of angiotensin I to angiotensin II. Angiotensin II is a potent vasoconstrictor, and by blocking its production, ACE inhibitors help dilate blood vessels, reduce blood pressure, and decrease the workload of the heart. Choice A is incorrect because it describes the mechanism of action of angiotensin receptor blockers (ARBs), not ACE inhibitors. Choice B is incorrect as it describes beta-blockers, not ACE inhibitors. Choice D is incorrect as ACE inhibitors do have a specific mechanism of action.

5. A healthcare professional is preparing to initiate IV therapy for an older adult client. Which of the following actions should the professional plan to take?

• A. Use an electric shaver to remove excess hair on the extremity.
• B. Select the antecubital area to insert the IV catheter.
• C. Distend the veins by using a blood pressure cuff.
• D. Instruct the client to keep the extremity still during the procedure.

Correct answer: C

Rationale: Distending the veins using a blood pressure cuff is essential for facilitating visualization and access to the veins during IV catheter insertion. This technique helps healthcare professionals identify suitable veins, reducing the risk of complications like infiltration or hematoma formation. Using an electric shaver to remove hair on the extremity (Choice A) may increase the risk of micro-cuts and introduce infection. Selecting the antecubital area (Choice B) may not always be appropriate, as vein condition and accessibility vary among older adult clients. Instructing the client to keep the extremity still (Choice D) is important but is not directly related to preparing for IV therapy.
