Nokea
A client is experiencing muscle weakness in the upper extremities. The client raises an arm above the head but then loses the ability to maintain the position. Muscular dystrophy is suspected. Which diagnostic test would evaluate muscle weakness or deterioration?
- A. A serum calcium test
- B. An electromyography
- C. An arthroscopy
- D. A magnetic resonance imaging (MRI)
Correct Answer: B
Rationale: An electromyography tests the electrical potential of muscles and nerves leading to the muscles. It is done to evaluate muscle weakness or deterioration. A serum calcium test evaluates the calcium in the blood. An arthroscopy assesses changes in the joint. An MRI identifies abnormalities in the targeted area.

The nurse is teaching a nutrition class at the community center. Which instruction is most important to stress when teaching on calcium intake?
- A. Eat green, leafy vegetables.
- B. Drink calcium- and vitamin D-fortified orange juice
- C. Provide age-related calcium intake recommendations.
- D. Maintain dairy sources of calcium intake.
Correct Answer: C
Rationale: Providing accurate and specific age-related daily calcium intake guidelines empowers clients to meet those recommendations in a manner that fits their lifestyle. It is also important to emphasize that calcium intake guidelines increase to 1200 mg/day for those older than age 50 years. Eating green, leafy vegetables is an important source of calcium as well as drinking fortified orange juice. Dairy sources also provide calcium intake in varying degrees.
A nurse is preparing a presentation for a health class about ways to ensure bone health, including the need for an adequate calcium intake. The participants are high school-aged girls. The nurse would encourage them to consume adequate calcium to maximize peak bone mass by which age?
- A. 20 years
- B. 30 years
- C. 40 years
- D. 50 years
Correct Answer: B
Rationale: Peak bone mass is attained sometime around 30 years of age. An adequate calcium intake before that time helps to maximize peak bone mass. This would result in denser bones that would be less susceptible to fracture. Bone mass begins to decrease after age 30.
The nurse is reporting on the results of client blood work to the oncoming nurse. Upon reviewing the data, the nurse notes that the client has an elevated uric acid level. Which inflammatory process would the nurse screen for on shift rounds?
- A. Inflammation arthritis
- B. Lupus erythematous
- C. Osteoporosis
- D. Gout
Correct Answer: D
Rationale: Gout is a medical condition with symptoms of acute inflammatory arthritis that is caused by high levels of uric acid in the blood. The client has uric acid crystal deposits in the joint. The nurse would assess joint areas for pain, redness, and swelling. Rheumatoid arthritis is a chronic disease of joint inflammation and pain. Lupus erythematosus is a chronic tissue disorder of the connective tissue and is known to have an elevated antinuclear antibody level. Osteoporosis has a deficiency in the serum calcium level.
A nurse is caring for a client with an undiagnosed bone disease. When instructing on the normal process to maintain bone tissue, which process transforms osteoblasts into mature bone cells?
- A. Remodelling
- B. Resorption
- C. Ossification and calcification
- D. Epiphyses and diaphysis formation
Correct Answer: C
Rationale: Ossification and calcification transform osteoblasts into mature bone cells called osteocytes. Osteocytes are involved in maintaining bone tissue. Resorption and remodelling are involved in bone destruction. Epiphyses and diaphysis are bone tissues that provide strength and support to the human skeleton.
The nurse is providing client education on growth and development throughout the lifespan. When stating periods of most rapid bone growth, which period is the nurse most correct to state?
- A. Period of conception
- B. Prenatally
- C. From birth through puberty
- D. Throughout adulthood
Correct Answer: C
Rationale: The period of most rapid bone growth is in the period of birth through puberty. Cell division occurs in the period of conception. Growth and organ development occurs prenatally. Throughout adulthood, growth is limited and may decrease. Instruction on the foundation of bone health such as with adequate sources of calcium and vitamin D are essential.
