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. What information should the practical nurse provide to a female client who started taking an oral sulfonamide for a urinary tract infection the previous day and reports slight anorexia, while also experiencing urinary frequency?

• A. Take the medication with an antacid instead of cranberry juice to reduce the anorexia.
• B. Continue to take the medication with a sip of cranberry juice, restricting fluids until the frequency is controlled.
• C. Continue to drink cranberry juice, but take the medicine on an empty stomach with a full glass of water.
• D. Take the medication with a spoonful of ice cream or applesauce and avoid drinking cranberry juice.

Correct answer: C

Rationale: The practical nurse should advise the client to take sulfonamides with a full glass of water to help prevent crystalluria. It is essential to take the medication on an empty stomach, ideally 1 hour before eating or 2 hours after eating to maximize its absorption and effectiveness. Continuing to drink cranberry juice is beneficial, but it is important to take the medicine separately to enhance its therapeutic action.

3. A client is prescribed nitroglycerin sublingual tablets. The practical nurse should reinforce which instruction?

• A. Store the tablets in a cool, dry place.
• B. Take one tablet every 5 minutes until pain is relieved, up to three tablets.
• C. Swallow the tablets whole.
• D. Chew the tablets for faster relief.

Correct answer: A

Rationale: Nitroglycerin sublingual tablets are sensitive to heat and moisture, so they should be stored in a cool, dry place to maintain their efficacy. Storing them in a cool, dry place helps prevent degradation of the medication. Choice B is incorrect because nitroglycerin tablets should be taken as directed by the healthcare provider to avoid potential overdose or adverse effects. Choice C is incorrect because sublingual tablets should be placed under the tongue to dissolve and be absorbed, not swallowed, to ensure their quick action. Choice D is incorrect because sublingual tablets should not be chewed; they are meant to be absorbed through the tissues under the tongue, and chewing them may alter their effectiveness.

4. A client who is newly diagnosed with erosive esophagitis secondary to GERD experiences symptoms after taking lansoprazole PO for one full week. Which actions should the nurse take?

• A. Confirm that the client is taking the medication correctly
• B. Auscultate the client's bowel sounds and assess the apical pulse
• C. Advise the client that healing typically takes several weeks
• D. Notify the healthcare provider to consider a higher dose

Correct answer: C

Rationale: The correct action for the nurse to take in this situation is to advise the client that healing from erosive esophagitis typically takes several weeks. Providing this information helps manage the client's expectations and anxiety about treatment effectiveness. It is not necessary to confirm medication timing, assess bowel sounds, or measure the apical pulse at this point. Since symptoms persist after one week of lansoprazole, it may not be appropriate to immediately escalate to a higher dose without further assessment or guidance from the healthcare provider. Auscultating bowel sounds and assessing the apical pulse are not relevant to the client's symptoms related to erosive esophagitis and GERD.

5. A client has a prescription for heparin 1,000 units IV STAT. Several pre-filled syringes of low molecular weight heparin are available in the client's medication drawer. Which action should the nurse implement?

• A. Dilute the available heparin in 250ml of normal saline solution prior to IV administration
• B. Advise the pharmacy on the need to deliver a vial of heparin to the nursing unit immediately
• C. Calculate and administer the equivalent dose of the available low molecular weight heparin
• D. Request a prescription to change the route of administration and use the available heparin

Correct answer: B

Rationale: In this scenario, the nurse should contact the pharmacy to obtain the correct heparin formulation as the prescription calls for heparin 1,000 units IV STAT. Low molecular weight heparin is not the same as unfractionated heparin, and therefore, the nurse should not administer the available low molecular weight heparin without first obtaining the correct medication. Diluting the available heparin, calculating an equivalent dose, or changing the route of administration would not address the discrepancy between the prescribed heparin and the available low molecular weight heparin.
