1. What is the most common cause of HHNS?

• A. Insulin overdose
• B. Removal of the adrenal gland
• C. Undiagnosed, untreated hyperpituitarism
• D. Undiagnosed, untreated diabetes mellitus

Correct answer: D

Rationale: The correct answer is D: Undiagnosed, untreated diabetes mellitus. Hyperosmolar hyperglycemic nonketotic syndrome (HHNS) is most commonly caused by undiagnosed and untreated diabetes mellitus. Insulin overdose (Choice A) is not a typical cause of HHNS; it is more related to hypoglycemia. Removal of the adrenal gland (Choice B) can lead to adrenal insufficiency but is not a common cause of HHNS. Undiagnosed, untreated hyperpituitarism (Choice C) is not a usual cause of HHNS; it is more related to pituitary hormone imbalances rather than hyperglycemia.

2. Which skin disorder most closely resembles and mimics dandruff?

• A. Lice infestation
• B. Scabies
• C. Dermatitis
• D. Acne vulgaris

Correct answer: C

Rationale: Dermatitis can closely resemble and mimic dandruff due to similar symptoms like flaking and itching. Lice infestation (choice A) is characterized by the presence of lice and their eggs attached to the hair shaft, different from dandruff. Scabies (choice B) is a contagious skin condition caused by mites, presenting as burrows, rashes, and intense itching, not typically resembling dandruff. Acne vulgaris (choice D) is a skin condition involving hair follicles and sebaceous glands, manifesting as pimples and inflammation, which is distinct from dandruff.

3. 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.

4. You are caring for a neonate who has a cleft palate. You should inform the mother that surgical correction will be done when the infant is:

• A. 8 to 12 months of age.
• B. 20 to 24 months of age.
• C. 16 to 20 months of age.
• D. 12 to 16 months of age.

Correct answer: A

Rationale: The correct answer is A: 8 to 12 months of age. Surgical correction for a cleft palate is typically performed around this age to optimize speech development and prevent feeding difficulties. Options B, C, and D suggest later ages for surgery, which may lead to speech and feeding issues due to the delay in correction.

5. Select the cranial nerve that is accurately paired with its name.

• A. The fourth cranial nerve: The trochlear nerve
• B. The twelfth cranial nerve: The hypoglossal nerve
• C. The tenth cranial nerve: The olfactory nerve
• D. The thirteenth cranial nerve: The auditory nerve

Correct answer: B

Rationale: The twelfth cranial nerve is the hypoglossal nerve, which controls the muscles of the tongue. The other choices are incorrect because the trochlear nerve is the fourth cranial nerve responsible for eye movement, the olfactory nerve is the first cranial nerve responsible for the sense of smell, and there are only twelve cranial nerves, so there is no thirteenth cranial nerve.
