Nursing Elites

1. Which of the following eye disorders manifests with red eye, pain, and visual acuity changes?

• A. Bacterial conjunctivitis
• B. Acute closed-angle glaucoma
• C. Chronic open-angle glaucoma
• D. Blepharitis

Correct answer: B

Rationale: Acute closed-angle glaucoma presents with symptoms such as a red eye, severe pain, and rapid visual acuity changes due to increased intraocular pressure. This condition is considered an ophthalmologic emergency. Bacterial conjunctivitis typically presents with redness, discharge, and irritation but is not associated with severe pain or visual changes. Chronic open-angle glaucoma is usually asymptomatic until advanced stages and does not typically present with acute pain. Blepharitis involves inflammation of the eyelid margins and is characterized by redness and irritation, but it does not cause severe pain or acute visual changes.

2. In Guillain-Barre syndrome, what pathophysiologic process underlies the deficits that accompany the degeneration of myelin in the peripheral nervous system (PNS)?

• A. The destruction of myelin results in a reduction in Schwann cell production in the client's PNS.
• B. The lack of myelin surrounding nerve cells compromises the axonal transport system.
• C. Without remyelination, the axon will eventually die.
• D. A deficit of myelin makes the client more susceptible to infection by potential pathogens.

Correct answer: C

Rationale: In Guillain-Barre syndrome, the destruction of myelin leads to axonal damage. If remyelination does not occur, the axon will eventually degenerate and die, impacting nerve function. Choice A is incorrect because the destruction of myelin does not affect Schwann cell production. Choice B is incorrect as the lack of myelin directly affects the conduction of nerve impulses, not the axonal transport system. Choice D is incorrect as a deficit of myelin does not predispose the client to infections by potential pathogens.

3. A patient with breast cancer is prescribed tamoxifen (Nolvadex). What critical information should the nurse provide during patient education?

• A. Tamoxifen may increase the risk of venous thromboembolism, so patients should be educated about the signs and symptoms of blood clots.
• B. Tamoxifen may decrease the risk of osteoporosis, so adequate calcium intake is important.
• C. Tamoxifen may cause weight gain, so patients should monitor their diet.
• D. Tamoxifen may increase the risk of breast cancer, so regular mammograms are essential.

Correct answer: A

Rationale: When a patient is prescribed tamoxifen, a critical piece of information that the nurse should provide during patient education is that tamoxifen may increase the risk of venous thromboembolism. Therefore, patients should be educated about the signs and symptoms of blood clots and advised to seek immediate medical attention if they occur. Choice B is incorrect because tamoxifen does not decrease the risk of osteoporosis. Choice C is incorrect as weight gain is a possible side effect of tamoxifen, but it is not a critical piece of information compared to the risk of venous thromboembolism. Choice D is incorrect because tamoxifen is actually used to treat breast cancer, not increase its risk.

4. A patient with hypogonadism is being treated with testosterone gel. What application instructions should the nurse provide?

• A. Apply the gel to the face and neck for maximum absorption.
• B. Apply the gel to the chest or upper arms and allow it to dry completely before dressing.
• C. Apply the gel to the genitals for improved results.
• D. Apply the gel to the scalp and back.

Correct answer: B

Rationale: The correct answer is B. Testosterone gel should be applied to the chest or upper arms and allowed to dry completely before dressing to avoid transfer to others. Applying the gel to the face, neck, genitals, scalp, or back is not recommended as these areas may lead to unintentional transfer to others, inappropriate absorption, or potential side effects. Choice A is incorrect as applying the gel to the face and neck can lead to unwanted transfer. Choice C is incorrect as applying the gel to the genitals is not the recommended site for application. Choice D is incorrect as the scalp and back are not appropriate sites for applying testosterone gel.

5. Why is it important for a patient to take a new oral contraceptive at the same time each day?

• A. Taking the medication at the same time each day helps maintain stable hormone levels, which is critical for preventing pregnancy.
• B. Taking the medication at the same time each day reduces the risk of breakthrough bleeding.
• C. Taking the medication at the same time each day ensures consistent absorption and effectiveness.
• D. Taking the medication at the same time each day is important, but missing a dose occasionally is not a concern.

Correct answer: A

Rationale: The correct answer is A. Taking oral contraceptives at the same time each day is crucial for maintaining stable hormone levels, which is essential for the contraceptive's effectiveness in preventing pregnancy. Choice B is incorrect because the primary reason for taking the medication consistently is hormone level stability, not specifically to reduce breakthrough bleeding. Choice C is incorrect as it focuses on absorption and effectiveness, which are important but do not address the main reason for consistent timing. Choice D is incorrect because missing doses can impact contraceptive efficacy, making consistent timing essential for optimal protection.
