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. 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.

3. A client has a new diagnosis of chlamydia. Which of the following actions should the nurse take?

A. Report the infection to the local health department
B. Apply an antiviral cream to lesions
C. Instruct the client to use condoms until the treatment is completed
D. Initiate contact precautions

Correct answer: A

Rationale: The correct answer is to report the infection to the local health department. Chlamydia is a reportable disease, meaning healthcare providers are required to report cases to public health authorities for tracking and control measures. Choice B is incorrect because chlamydia is a bacterial infection, not a viral infection, so antiviral cream would not be effective. Choice C is important advice for preventing the spread of chlamydia but is not the priority in this scenario. Choice D is not necessary for chlamydia, as it is primarily transmitted through sexual contact.

4. 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.

5. Which anatomic malformations are associated with Tetralogy of Fallot?

A. A sub-aortic septal defect, an overriding aorta, left ventricular hypertrophy, and right ventricular outflow
B. A sub-aortic septal defect, an overriding aorta, right ventricular hypertrophy, and left ventricular outflow
C. A sub-aortic septal defect, an overriding aorta, pulmonary atresia, and right ventricular outflow
D. A sub-aortic septal defect, an overriding aorta, right ventricular hypertrophy, and right ventricular outflow

Correct answer: D

Rationale: Tetralogy of Fallot is characterized by a combination of four heart defects: a sub-aortic septal defect, an overriding aorta, right ventricular hypertrophy, and right ventricular outflow obstruction. This leads to mixing of oxygen-poor and oxygen-rich blood, resulting in cyanosis. Therefore, the correct answer is D. Choices A, B, and C are incorrect because they do not accurately describe the specific combination of anatomic malformations seen in Tetralogy of Fallot.
