A nurse is planning the care of an older adult client with osteomalacia. What action should the nurse recommend in order to promote vitamin D synthesis?
Ensuring adequate exposure to sunlight
Eating a low-purine diet
Performing cardiovascular exercise while avoiding weight-bearing exercises
Taking thyroid supplements as prescribed
The Correct Answer is A
A. Ensuring adequate exposure to sunlight: Sunlight exposure stimulates the skin to produce vitamin D, which is essential for calcium absorption and bone mineralization. Older adults with osteomalacia often have deficiencies due to limited sun exposure. Encouraging regular, safe time in natural sunlight helps improve vitamin D levels and supports bone health.
B. Eating a low-purine diet: A low-purine diet is typically recommended for clients with gout, not osteomalacia. It helps reduce uric acid levels but has no known benefits in enhancing vitamin D synthesis or improving bone mineralization in osteomalacia.
C. Performing cardiovascular exercise while avoiding weight-bearing exercises: Weight-bearing exercises are beneficial in osteomalacia as they help strengthen bones and prevent further demineralization. Avoiding these exercises could lead to worsening bone weakness.
D. Taking thyroid supplements as prescribed: Thyroid supplements are used to treat hypothyroidism and are unrelated to vitamin D metabolism. Taking these supplements does not contribute to vitamin D synthesis or address the pathophysiology of osteomalacia.

Correct Answer is A
Explanation
A. Providing ventilatory assistance: Myasthenic crisis involves severe muscle weakness, including the respiratory muscles, posing an immediate threat to airway and breathing. Ventilatory support is the highest priority to maintain oxygenation and prevent respiratory failure during this acute phase.
B. Facilitating ABG analysis: Arterial blood gas analysis is useful in evaluating respiratory status but does not take precedence over actually ensuring adequate ventilation. ABGs are diagnostic tools and should follow stabilization of the airway and breathing.
C. Suctioning secretions: Suctioning may be necessary, especially if the client has difficulty clearing secretions. However, suctioning is secondary to establishing ventilatory support, which addresses the root issue of respiratory insufficiency.
D. Administering tube feedings: Tube feeding is important for nutrition but is not an immediate concern in a myasthenic crisis. During respiratory compromise, maintaining a patent airway and supporting ventilation must come first before addressing nutritional needs.
Correct Answer is D
Explanation
A. Function of the spinal nerve: Spinal nerves control motor and sensory function throughout the body, but tongue movement is not associated with spinal nerve function. Testing tongue movement specifically assesses cranial nerve activity.
B. Function of the trochlear nerve: The trochlear nerve (cranial nerve IV) controls the superior oblique muscle of the eye, allowing for downward and inward eye movement. It does not influence tongue motion or position.
C. Function of the vagus nerve: The vagus nerve (cranial nerve X) controls parasympathetic functions and plays a role in swallowing, heart rate, and voice quality, but it does not govern voluntary tongue movements.
D. Function of the hypoglossal nerve: The hypoglossal nerve (cranial nerve XII) controls the muscles of the tongue, allowing for movement such as sticking it out and moving it side to side. This is the nerve specifically assessed by the described action.
