A 40-year-old client reports chronic lower back pain and stiffness. X-rays of the lumbar spine confirm the diagnosis of moderate to severe osteoarthritis. The nurse identifies which predisposing factor may have led to these degenerative changes?

Weekly aerobic exercise at a gym

Vitamin D deficiency

Weight of <60 kg

Trauma

Answer and Explanation

The Correct Answer is B

Choice A Reason:
Weekly aerobic exercise at a gym is generally beneficial for joint health and is not a predisposing factor for osteoarthritis. Regular physical activity helps maintain joint flexibility, muscle strength, and overall health, which can actually help prevent the development of osteoarthritis.

Choice B Reason:
Vitamin D deficiency has been associated with an increased risk of osteoarthritis. Vitamin D is essential for bone health, and a deficiency can lead to changes in bone structure and strength, potentially contributing to the development and progression of osteoarthritis.

Choice C Reason:
A weight of less than 60 kg does not typically predispose an individual to osteoarthritis. In fact, maintaining a healthy weight can reduce the risk of developing osteoarthritis, as excess body weight can increase the stress on joints.

Choice D Reason:
Trauma can lead to post-traumatic osteoarthritis, which is a form of osteoarthritis that develops after an injury to a joint. Traumatic injuries can damage the cartilage and bone, leading to degenerative changes and osteoarthritis.

Correct Answer is B

Explanation

Choice A Reason:
Asking the client to share the joke may imply that the nurse believes the client is laughing at a joke, which may not be the case. It's important to recognize that uncontrollable laughter can be a symptom of schizophrenia and not necessarily a response to humor.

Choice B Reason:
This response is open-ended and nonjudgmental, inviting the client to explain their behavior without making assumptions. It allows the client to share their experience, which could be related to an internal stimulus such as a hallucination or simply a response they cannot control.

Choice C Reason:
Asking "Why are you laughing?" could be perceived as confrontational or accusatory. It might make the client feel defensive or misunderstood, especially if the laughter is a symptom of their condition and not something they are doing voluntarily.

Choice D Reason:
Saying "I don't think I said anything funny" focuses on the nurse's perspective rather than the client's experience. It could inadvertently dismiss the client's behavior as inappropriate or unjustified, which is not supportive in a therapeutic relationship.

A. Give the ordered dose of dantrolene. B. Call the physician for an order for metoprolol. C. Increase the rate of lactated Ringer's. D. Ask the physician to order liver function tests.

Correct Answer is A

Explanation

Choice A Reason:
Dantrolene is used in the management of malignant hyperthermia, a life-threatening complication characterized by muscle rigidity and elevated temperature, often triggered by certain anesthetics. The patient's symptoms of muscle rigidity and brown urine, which may indicate myoglobinuria, along with elevated temperature and heart rate, are suggestive of this condition. Dantrolene acts by reducing calcium release from the sarcoplasmic reticulum of skeletal muscle, thereby reducing muscle contraction and metabolic demand.

Choice B Reason:
Metoprolol, a beta-blocker, is not the first-line treatment for symptoms suggestive of malignant hyperthermia. While it can reduce heart rate and blood pressure, it does not address the underlying pathophysiology of malignant hyperthermia and is not indicated in this scenario.

Choice C Reason:
Increasing the rate of lactated Ringer's solution is not the primary intervention for malignant hyperthermia. While maintaining hydration is important, it does not directly counteract the pathophysiological processes at play in malignant hyperthermia.

Choice D Reason:
While liver function tests can be important in assessing overall organ function post-operatively, they are not the immediate priority in a suspected case of malignant hyperthermia. The priority is to treat the acute and life-threatening symptoms first.
