health assessment practice questions

Correct Answer: C

Rationale: The correct answer is C: Bell's palsy. Bell's palsy is characterized by sudden weakness or paralysis of the facial muscles, resulting in drooping of the face, inability to raise the eyebrow or close the eye, and difficulty with facial expressions and functions like whistling. In this case, the patient's symptoms of left-sided facial paralysis point towards Bell's palsy as the likely diagnosis. Cushing's syndrome (A) is a hormonal disorder, Parkinson's syndrome (B) is a neurodegenerative disorder affecting movement, and a cerebrovascular accident (D) typically presents with more generalized neurological deficits rather than isolated facial paralysis.

Correct Answer: B

Rationale: The correct answer is B: Dehydration. Depressed and sunken fontanelles in an infant indicate dehydration due to decreased fluid volume. Dehydration causes a decrease in tissue turgor, leading to the fontanelles appearing sunken. Rickets (A) is a condition characterized by weak or soft bones due to vitamin D deficiency. Mental retardation (C) is a developmental disorder, not related to fontanelle appearance. Increased intracranial pressure (D) would cause bulging fontanelles, not depressed fontanelles. Therefore, the most likely condition in this case is dehydration.

Correct Answer: D

Rationale: The correct answer is D because testing for strabismus by performing the corneal light reflex test is crucial in diagnosing "lazy eye" or amblyopia in children. Strabismus is a condition where the eyes are misaligned, leading to poor vision in one eye. By performing the corneal light reflex test, the nurse can assess if the child's eyes are aligned or if there is deviation, which could indicate lazy eye. Options A, B, and C are incorrect as they do not specifically address the assessment of strabismus, which is the key indicator for lazy eye in this scenario.

Correct Answer: C

Rationale: The correct answer is C: Bell's palsy. Bell's palsy is characterized by sudden weakness or paralysis of the facial muscles, resulting in drooping of the face, inability to raise the eyebrow or close the eye, and difficulty with facial expressions and functions like whistling. In this case, the patient's symptoms of left-sided facial paralysis point towards Bell's palsy as the likely diagnosis. Cushing's syndrome (A) is a hormonal disorder, Parkinson's syndrome (B) is a neurodegenerative disorder affecting movement, and a cerebrovascular accident (D) typically presents with more generalized neurological deficits rather than isolated facial paralysis.

Correct Answer: C

Rationale: The correct answer is C: at the level of the C7 vertebra. The vertebra prominens refers to the spinous process of the C7 vertebra, which is the most prominent bony landmark at the base of the neck. Assessing this area allows the nurse to accurately locate and evaluate tenderness reported by the physician. Choices A, B, and D are incorrect as they do not correspond to the location of the vertebra prominens. Option A is too high, above the diaphragm; option B is too low, lateral to the knee cap; and option D is too low, at the level of the T11 vertebra.
