Question 1 of 5
The functional units of the musculoskeletal system are the:
Correct Answer: A
Rationale: The correct answer is A: Joints. Joints are the functional units of the musculoskeletal system because they are the points where two or more bones meet and allow for movement. They are essential for flexibility and mobility. Bones (B) provide structure and support, muscles (C) generate movement, and tendons (D) connect muscles to bones, but joints are specifically responsible for facilitating movement and range of motion in the musculoskeletal system.
Question 2 of 5
A patient is able to flex his right arm forward without difficulty or pain but is unable to abduct his arm because of pain and muscle spasms. The nurse should suspect:
Correct Answer: B
Rationale: The correct answer is B: Rotator cuff lesions. The patient's ability to flex the arm without difficulty indicates intact muscles involved in flexion, ruling out crepitation. Inability to abduct due to pain and spasms points to rotator cuff involvement, not shoulder dislocation. Rheumatoid arthritis typically presents with symmetrical joint involvement, unlike the unilateral symptoms described.
Question 3 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 4 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 5 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.
