A nurse is preparing to perform ocular irrigation for a client following a chemical splash to the eye.

Which of the following actions should the nurse plan to take first?

Place a strip of pH paper onto the cul-de-sac of the affected eye.

Administer proparacaine eye drops into the affected eye.

Install 0.9% sodium chloride solution into the affected eye.

Collect information about the irritant that caused the injury.

Answer and Explanation

The Correct Answer is D

The first action the nurse should take is to collect information about the irritant that caused the injury.
This information is important because it can help determine the appropriate treatment and irrigation solution to use.
Choice A is incorrect because airborne precautions are used to prevent the spread of infectious diseases that are transmitted through the air, and are not necessary in this situation.
Choice B is incorrect because administering proparacaine eye drops into the affected eye is not the first action the nurse should take.
Proparacaine is a topical anesthetic that can be used to numb the eye before performing ocular irrigation, but it is not the first action the nurse should take.
Choice C is incorrect because installing 0.9% sodium chloride solution into the affected eye is not the first action the nurse should take; the nurse should first collect information about the irritant that caused the injury before performing ocular irrigation.

Correct Answer is A

Explanation

First-degree heart block is a type of atrioventricular (AV) block that involves the consistent prolongation of the PR interval (defined as >0.20 seconds) due to delayed conduction via the atrioventricular node.
This is seen on an ECG as a PR interval greater than 200 ms in length.
Choice B: Nondiscernible P waves are not an answer because it is not mentioned as a characteristic of first-degree heart block in my sources.
Choice C: More P waves than QRS complexes is not an answer because it is not mentioned as a characteristic of first-degree heart block in my sources.
Choice D: No correlation between P and QRS waves is not an answer because it is not mentioned as a characteristic of first-degree heart block in my sources.

A. Initiate an IV dopamine infusion. B. Begin an IV bolus of lactated Ringer's. C. Perform neurological assessments. D. Place the client supine.

Correct Answer is C

Explanation

A hypertensive crisis is an emergent situation in which a marked elevation in diastolic blood pressure can cause end-organ damage.
The nurse should perform neurological assessments to monitor for any changes in the patient’s level of consciousness and other neurological symptoms.
Choice A is incorrect because dopamine is not typically used to treat hypertensive crises.
Choice B is incorrect because lactated Ringer’s solution is not typically used to treat hypertensive crises.
Choice D is incorrect because placing the client supine may not be appropriate and could potentially worsen their condition.
