Question 1 of 5
The nurse is explaining the mechanism of the growth of long bones to a mother of a toddler. Where does lengthening of the bones occur?
Correct Answer: C
Rationale: The correct answer is C: Epiphyses. Epiphyses are the ends of long bones where longitudinal growth occurs through the proliferation of cartilage cells in the growth plate. This process is known as endochondral ossification. Bursa (A) is a fluid-filled sac near joints, not involved in bone growth. Calcaneus (B) is a bone in the heel, not directly related to longitudinal bone growth. Tuberosities (D) are bony prominences for muscle attachment, not sites of bone lengthening.
Question 2 of 5
A mother brings her newborn baby boy in for a checkup; she tells the nurse that he does not seem to be moving his right arm as much as his left and that he seems to have pain when she lifts him up under the arms. The nurse suspects a fractured clavicle and would observe for:
Correct Answer: C
Rationale: The correct answer is C: Limited range of motion during the Moro reflex. This reflex involves the baby's response to a sudden loss of support or a loud noise, where they spread their arms and then bring them back in. In a newborn with a fractured clavicle, limited range of motion during the Moro reflex may indicate pain or discomfort in the affected arm, leading to decreased movement. Choice A, Negative Allis test, is not relevant to assessing a fractured clavicle in a newborn. Choice B, Positive Ortolani sign, is related to hip dislocation, not a fractured clavicle. Choice D, Limited range of motion during Lasègue test, is used to assess for sciatic nerve irritation in adults and is not applicable to a newborn with a suspected fractured clavicle.
Question 3 of 5
When assessing muscle strength, the nurse observes that a patient has complete range of motion against gravity with full resistance... What grade of muscle strength should the nurse record using a 0- to 5-point scale?
Correct Answer: D
Rationale: The correct answer is D (5) because the patient demonstrates normal muscle strength with complete range of motion against gravity and full resistance. A grade of 5 signifies normal strength. Choice A (2) indicates poor muscle strength with partial range of motion, B (3) indicates fair strength against gravity but not resistance, and C (4) indicates good strength against some resistance but not full resistance.
Question 4 of 5
The nurse is assessing the joints of a woman who has stated, 'I have a long family history of arthritis, and my joints hurt.' The nurse suspects that she has osteoarthritis. Which of these are symptoms of osteoarthritis? Select all that apply.
Correct Answer: B
Rationale: The correct answer is B: Asymmetric joint involvement. Osteoarthritis commonly presents with asymmetric joint involvement, unlike rheumatoid arthritis which typically affects joints symmetrically. This pattern of joint involvement aligns with the woman's complaint of joint pain rather than a broader systemic issue. Additionally, osteoarthritis is characterized by pain with motion of affected joints due to cartilage degeneration, supporting choice C. Swelling with hard, bony protuberances (choice D) is more indicative of osteophyte formation in osteoarthritis. In summary, the correct answer (B) aligns with the typical presentation of osteoarthritis, while choices A and D are more characteristic of other types of arthritis, and choice C is a common symptom shared with osteoarthritis.
Question 5 of 5
A 30-year-old woman tells the nurse that she has been very unsteady and has had difficulty in maintaining her balance. Which area of the brain that is related to these findings would concern the nurse?
Correct Answer: C
Rationale: The correct answer is C: Cerebellum. The cerebellum is responsible for coordinating voluntary movements, balance, and posture. Dysfunction in the cerebellum can lead to symptoms like unsteadiness and difficulty in maintaining balance. The thalamus (A) is involved in relaying sensory and motor signals, not specifically related to balance. The brainstem (B) is important for basic involuntary functions like breathing and heart rate, not specifically balance. The extrapyramidal tract (D) is involved in motor control but not directly related to balance and coordination.
