Answer and Explanation

The Correct Answer is C

Metamucil Psyllium Fiber Supplement Sugar-Free Orange Smooth Powder - Shop Medicines & Treatments at H-E-B

The correct answer is c. The importance of consuming adequate amounts of water.

Rationale for Choice A:

Statement: The need to monitor for systemic side effects.
Rationale: It's not accurate to prioritize monitoring for systemic side effects when teaching a patient about psyllium (Metamucil). Psyllium is a bulk-forming laxative that primarily acts within the gastrointestinal tract, and systemic side effects are rare. While it's essential to be aware of potential side effects, focusing on them during initial teaching might cause unnecessary anxiety.

Rationale for Choice B:

Statement: The need to use the dry form of Metamucil to prevent cramping.
Rationale: This statement is incorrect. It's generally recommended to mix psyllium with water or another liquid before ingestion. Consuming the dry form can increase the risk of choking and might not adequately hydrate stool.

Rationale for Choice C:

Statement: The importance of consuming adequate amounts of water.
Rationale: This is the most crucial information to emphasize when teaching about psyllium. Psyllium works by absorbing water and forming a bulky gel that softens stool and promotes bowel movements. Without sufficient water intake, psyllium can cause constipation to worsen or lead to intestinal obstruction.

Rationale for Choice D:

Statement: The onset of action of 30 to 60 minutes after administration.
Rationale: This statement is inaccurate. Psyllium is not a fast-acting laxative. It typically takes 12-72 hours to produce a bowel movement. Informing patients about the expected time frame for results is essential to manage expectations and prevent unnecessary medication overuse.

Correct Answer is D

Explanation

Oxygen cannot diffuse rapidly across the membrane to tissues in the eye. Diabetic retinopathy is caused by damage to the blood vessels of the retina, which is the light-sensitive tissue at the back of the eye. This damage can reduce the oxygen supply to the retina and lead to vision problems.

Choice A is wrong because cells in the eye can reproduce normally, but they may not function properly due to high blood sugar levels or lack of oxygen.

Choice B is wrong because diabetic retinopathy does not affect the production of aqueous humor, which is the fluid that fills the front part of the eye.

However, diabetes can cause another eye condition called glaucoma, which is caused by increased pressure from too much aqueous humor.

Choice C is wrong because diabetic retinopathy does not affect the nerve innervations throughout the eye.

However, diabetes can cause another eye condition called diabetic neuropathy, which is caused by damage to the nerves that control eye movement and pupil dilation.

A. 08:00. B. 22:00. C. 06:00. D. 16:00.

Correct Answer is C

Explanation

This is because cortisol exhibits a proper 24-h circadian rhythm that affects the cardiovascular system and other organs. Cortisol levels are normally low at the beginning of sleep and high at the moment of awakening. Taking corticosteroids at this time mimics the natural cortisol rhythm and may reduce side effects such as adrenal suppression, sleep disturbances and cardiovascular complications.

Choice A is wrong because taking corticosteroids at 08:00 may not coincide with the client’s natural cortisol peak and may cause insomnia or unpleasant dreams.

Choice B is wrong because taking corticosteroids at 22:00 may disrupt the client’s sleep quality and increase the risk of nocturnal hypertension.

Choice D is wrong because taking corticosteroids at 16:00 may interfere with the client’s natural cortisol decline and cause hyperglycemia or dyslipidemia.
