A nurse is explaining a patient's decreasing bone density in terms of the balance between bone resorption and formation. What dietary nutrients and hormones play a role in the resorption and formation of adult bones?
- A. Thyroid hormone
- B. Growth hormone
- C. Estrogen
- D. Vitamin B12
- E. Luteinizing hormone
Correct Answer: A,B,C
Rationale: The balance between bone resorption and formation is influenced by the following factors: physical activity; dietary intake of certain nutrients, especially calcium; and several hormones, including calcitriol (i.e., activated vitamin D), parathyroid hormone (PTH), calcitonin, thyroid hormone, cortisol, growth hormone, and the sex hormones estrogen and testosterone. Luteinizing hormone and vitamin B12 do not play a role in bone formation or resorption.

A patient has just had an arthroscopy performed to assess a knee injury. What nursing intervention should the nurse implement following this procedure?
- A. Wrap the joint in a compression dressing.
- B. Perform passive range of motion exercises.
- C. Maintain the knee in flexion for up to 30 minutes.
- D. Apply heat to the knee.
Correct Answer: A
Rationale: Interventions to perform following an arthroscopy include wrapping the joint in a compression dressing, extending and elevating the joint, and applying ice or cold packs. Passive ROM exercises, static flexion, and heat are not indicated.
A nurse is assessing a patient who is experiencing peripheral neurovascular dysfunction. What assessment findings are most consistent with this diagnosis?
- A. Hot skin with a capillary refill of 1 to 2 seconds
- B. Absence of feeling, capillary refill of 4 to 5 seconds, and cool skin
- C. Pain, diaphoresis, and erythema
- D. Jaundiced skin, weakness, and capillary refill of 3 seconds
Correct Answer: B
Rationale: Indicators of peripheral neurovascular dysfunction include pale, cyanotic, or mottled skin with a cool temperature; capillary refill greater than 3 seconds; weakness or paralysis with motion; and paresthesia, unrelenting pain, pain on passive stretch, or absence of feeling. Jaundice, diaphoresis, and warmth are inconsistent with peripheral neurovascular dysfunction.
A nurse is taking a health history on a patient with musculoskeletal dysfunction. What is the primary focus of this phase of the nurse's assessment?
- A. Evaluating the effects of the musculoskeletal disorder on the patient's function
- B. Evaluating the patient's adherence to the existing treatment regimen
- C. Evaluating the presence of genetic risk factors for further musculoskeletal disorders
- D. Evaluating the patient's active and passive range of motion
Correct Answer: A
Rationale: The nursing assessment of the patient with musculoskeletal dysfunction includes an evaluation of the effects of the musculoskeletal disorder on the patient. This is a vital focus of the health history and supersedes the assessment of genetic risk factors and adherence to treatment, though these are both valid inclusions to the interview. Assessment of ROM occurs during the physical assessment, not the interview.
An older adult patient has come to the clinic for a regular check-up. The nurse's initial inspection reveals an increased thoracic curvature of the patient's spine. The nurse should document the presence of which of the following?
- A. Scoliosis
- B. Epiphyses
- C. Lordosis
- D. Kyphosis
Correct Answer: D
Rationale: Kyphosis is the increase in thoracic curvature of the spine. Scoliosis is a deviation in the lateral curvature of the spine. Epiphyses are the ends of the long bones. Lordosis is the exaggerated curvature of the lumbar spine.
The nurse is performing an assessment of a patient's musculoskeletal system and is appraising the patient's bone integrity. What action should the nurse perform during this phase of assessment?
- A. Compare parts of the body symmetrically.
- B. Assess extremities when in motion rather than at rest.
- C. Percuss as many joints as accessible.
- D. Administer analgesia 30 to 60 minutes before assessment.
Correct Answer: A
Rationale: When assessing bone integrity, symmetric parts of the body, such as extremities, are compared. Analgesia should not be necessary and percussion is not a clinically useful assessment technique. Bone integrity is best assessed when the patient is not moving.
