health assessment practice questions Questions
Question 1 of 5
A mother who has brought her newborn infant for assessment tells the nurse that she has noticed that whenever her newborn's head is turned to the right side, the baby straightens out the arm and leg on the same side and flexes the opposite arm and leg. After confirming this on examination, the nurse would tell the mother that this is:
Correct Answer: C
Rationale: Step 1: The described behavior is known as the asymmetric tonic neck reflex (ATNR), a normal infantile reflex. Step 2: The ATNR typically emerges around birth and should disappear between 3 and 4 months of age. Step 3: The reflex helps with hand-eye coordination and development of body awareness. Step 4: Choice A is incorrect as the behavior is not abnormal or related to atonic neck reflex. Step 5: Choice B is incorrect as the reflex typically disappears by 3-4 months, not by the first year of life. Step 6: Choice D is incorrect as it describes a different pattern of movement than what is observed in the ATNR. Summary: The correct answer is C because the behavior described is a normal infantile reflex that typically disappears between 3-4 months of age, aiding in the baby's development.
Question 2 of 5
During the assessment of an infant, the nurse notes that the fontanelles are depressed and sunken. Which condition does the nurse suspect?
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.
Question 3 of 5
During the examination of a patient in her third trimester of pregnancy, the nurse notices that the patient's thyroid gland is slightly enlarged. No enlargement had been noted previously. The nurse suspects that:
Correct Answer: C
Rationale: Step-by-step rationale for why choice C is correct: 1. Enlargement of the thyroid gland during pregnancy is a normal finding due to hormonal changes. 2. The thyroid gland enlarges to meet the increased demands of thyroid hormone production. 3. This condition is known as gestational thyrotoxicosis and is usually benign. 4. No further testing is needed for thyroid cancer unless other concerning symptoms are present. Summary: A: Not relevant as iodine deficiency is not typically associated with thyroid enlargement in pregnancy. B: Incorrect as early signs of goitre would involve more pronounced symptoms than just slight enlargement. D: Unnecessary as thyroid cancer is not a common concern in this scenario of a slightly enlarged thyroid in the third trimester of pregnancy.
Question 4 of 5
During an examination, the nurse finds that a patient's left temporal artery is more tortuous and feels hardened and tender compared with the right temporal artery. What condition does the nurse suspect?
Correct Answer: C
Rationale: The correct answer is C: Temporal arteritis. Temporal arteritis is characterized by inflammation of the temporal arteries, leading to symptoms such as tenderness, hardness, and tortuosity. The left temporal artery being more affected than the right is a common presentation. Crepitation (choice A) refers to a crackling sound or sensation, typically associated with bone or joint abnormalities, not arterial inflammation. Mastoiditis (choice B) is an infection of the mastoid bone behind the ear, not related to temporal arteries. Bell's palsy (choice D) is a condition affecting facial nerves, not arteries.
Question 5 of 5
When examining a patient's eyes, the nurse knows that stimulation of the sympathetic branch of the autonomic nervous system:
Correct Answer: C
Rationale: The correct answer is C because stimulation of the sympathetic branch of the autonomic nervous system results in the elevation of the eyelid (ptosis) and dilation of the pupil (mydriasis). This is due to the action of the dilator pupillae muscle and the superior tarsal muscle. Pupillary constriction (choice A) is controlled by the parasympathetic branch via the sphincter pupillae muscle. Adjusting the eye for near vision (choice B) is controlled by the ciliary muscle, which is under parasympathetic control, not sympathetic. Contraction of the ciliary body (choice D) is also controlled by the parasympathetic system for accommodation of near vision, not the sympathetic system.
