1. Diabetes insipidus is the result of:

• A. A diet high in sugar and carbohydrates.
• B. A complicated pregnancy.
• C. A disorder of the pancreas.
• D. A disorder of the pituitary gland.

Correct answer: D

Rationale: Diabetes insipidus is caused by a disorder of the pituitary gland affecting ADH regulation. This disorder results in the decreased production or release of antidiuretic hormone (ADH), leading to the inability of the kidneys to concentrate urine properly. Choices A, B, and C are incorrect as they do not relate to the underlying cause of diabetes insipidus.

2. Rotating injection sites when administering insulin prevents which of the following complications?

• A. Insulin edema
• B. Insulin lipodystrophy
• C. Insulin resistance
• D. Systemic allergic reactions

Correct answer: B

Rationale: Rotating injection sites when administering insulin helps prevent insulin lipodystrophy, which is the abnormal distribution of fat at injection sites. Insulin edema (choice A) is not prevented by rotating injection sites; it is characterized by swelling at the site of insulin injection due to increased capillary permeability. Insulin resistance (choice C) is a condition where the body's cells become less responsive to insulin, and rotating injection sites does not directly prevent this. Systemic allergic reactions (choice D) are not specifically prevented by rotating injection sites; they are related to an allergic response to insulin.

3. What are the fine, down-like hairs on the newborn's ears, shoulders, lower back, and/or forehead known as?

• A. Vernix.
• B. Lanugo.
• C. Milia.
• D. Vibrissae.

Correct answer: B

Rationale: Lanugo is the term used to describe the fine, down-like hairs found on a newborn's ears, shoulders, lower back, and/or forehead. These hairs are different from vernix, which is a waxy or cheese-like white substance covering the skin of newborns. Milia are small, white, or yellowish cysts that commonly appear on a newborn's face, while vibrissae are the thick, stiff hairs commonly found around the nose and other parts of the face.

4. What percentage of term newborns have a congenital heart disease due to environmental risk factors such as maternal alcoholism or drug ingestion?

• A. 2% to 4%
• B. 10% to 20%
• C. 5% to 10%
• D. 7% to 9%

Correct answer: A

Rationale: The correct answer is A: 2% to 4%. According to research, 2% to 4% of term newborns have congenital heart disease due to environmental risk factors such as maternal alcoholism or drug ingestion. Choices B, C, and D provide percentages that are higher than the actual prevalence of congenital heart disease in newborns caused by environmental factors, making them incorrect.

5. Which statement about glaucoma is true and accurate?

• A. Acute angle-closure glaucoma is an ocular emergency.
• B. Acute angle-closure glaucoma leads to the loss of peripheral vision and tunnel vision.
• C. Primary open-angle glaucoma leads to eye pain, nausea, and vomiting, blurry vision, and halos.
• D. Bubbles are implanted to protect the retina from glaucoma.

Correct answer: A

Rationale: The correct answer is A: 'Acute angle-closure glaucoma is an ocular emergency.' Acute angle-closure glaucoma is indeed considered an ocular emergency that requires immediate attention to prevent vision loss. Choice B is incorrect because acute angle-closure glaucoma commonly presents with symptoms like severe eye pain, headache, blurred vision, and halos around lights. Choice C is incorrect as these symptoms are more indicative of acute angle-closure glaucoma rather than primary open-angle glaucoma. Choice D is incorrect since bubbles are not typically used to protect the retina from glaucoma; treatment usually involves medications, laser therapy, or surgery to manage intraocular pressure.
