A nurse is preparing to administer ondansetron 4 mg IM stat.

The amount available is ondansetron for injection 2 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest whole number.

(Use a leading zero if it applies. Do not use a trailing zero)

Choice A rationale
Kernig’s sign is associated with meningitis, not hypocalcemia. It involves pain and resistance when attempting to extend the leg at the knee while the hip is flexed.
Choice B rationale
Brudzinski’s sign is also associated with meningitis, not hypocalcemia. It involves involuntary lifting of the legs when lifting a patient’s head.
Choice C rationale
Chvostek’s sign is a clinical sign of hypocalcemia. It involves twitching of the facial muscles in response to tapping over the facial nerve.
Choice D rationale
Cullen’s sign is associated with acute pancreatitis and involves bruising around the umbilicus. It is not related to hypocalcemia.

Choice A rationale
Providing a low protein diet is incorrect. Clients with COPD often require a high-protein diet to maintain muscle mass and support respiratory function. Protein is essential for the repair and maintenance of body tissues, including respiratory muscles. A low-protein diet could lead to muscle wasting and decreased respiratory function.
Choice B rationale
Instructing the client to cough every 4 hours is incorrect. Clients with COPD should be encouraged to perform controlled coughing techniques more frequently to clear secretions and prevent respiratory infections. Coughing every 4 hours may not be sufficient to maintain airway patency and prevent complications.
Choice C rationale
Advising the client to lie down after eating is incorrect. Clients with COPD should avoid lying down immediately after eating to prevent gastroesophageal reflux, which can exacerbate respiratory symptoms. Instead, they should remain upright for at least 30 minutes after meals to aid digestion and reduce the risk of aspiration.
Choice D rationale
Encouraging the client to drink 8 glasses of water a day is correct. Adequate hydration helps to thin mucus secretions, making them easier to expectorate. This can improve airway clearance and reduce the risk of respiratory infections. Additionally, staying hydrated supports overall health and well-being.
