The physician orders Ancef 500 mg IV for a urinary tract infection.
After reconstitution, the medication is available as 330 mg/mL. How many milliliters will the nurse administer?
The Correct Answer is ["1.52"]
Step 1 is: The physician ordered 500 mg and the available concentration is 330 mg/mL. To find the volume to administer, divide the ordered dose by the available concentration: 500 mg ÷ 330 mg/mL.
Step 2 is: 500 ÷ 330 = 1.5151.
Step 3 is: Round to the nearest hundredth as is common for medication administration: 1.52 mL.
Final answer: The nurse will administer 1.52 mL.

Correct Answer is C
Explanation
Choice A rationale
Trouble chewing foods such as meats and raw vegetables is more indicative of mechanical issues with chewing or dental problems rather than dysphagia, which primarily involves difficulty with swallowing. While chewing difficulties can sometimes coexist with dysphagia, the primary characteristic of dysphagia is impaired bolus transport from the mouth to the stomach.
Choice B rationale
Awakenings with a feeling of indigestion suggest issues related to gastric motility or acid reflux, not necessarily dysphagia. Indigestion involves discomfort in the upper abdomen, often related to the digestion of food in the stomach, whereas dysphagia is focused on the process of swallowing.
Choice C rationale
A feeling of choking after swallowing is a classic symptom of dysphagia. It indicates that food or liquid is not passing smoothly from the pharynx to the esophagus and may be entering the airway. This occurs due to impaired coordination or weakness of the muscles involved in swallowing.
Choice D rationale
Frequent burping, or eructation, is typically related to the release of excess gas from the stomach, often due to swallowed air or the breakdown of food. It is not a primary indicator of dysphagia, which is a disorder of the swallowing mechanism.
Correct Answer is ["A","D"]
Explanation
Choice A rationale
Vanilla pudding is often restricted in dysphagia diets due to its smooth, slippery texture, which can be difficult to control in the oral cavity and increases the risk of aspiration into the airway. Individuals with dysphagia may have impaired swallowing mechanisms, making thin, liquid-like consistencies particularly hazardous.
Choice B rationale
Cranberry juice is a thin liquid and poses a significant aspiration risk for a patient with dysphagia. Thin liquids are difficult to manage in the mouth and throat, increasing the likelihood of the liquid entering the trachea instead of the esophagus. Patients with swallowing difficulties often require thickened liquids to improve bolus control.
Choice C rationale
Beef broth is a clear liquid and, similar to cranberry juice, presents a high risk of aspiration for a patient with dysphagia. Its thin consistency makes it challenging for individuals with impaired swallowing to control its movement, potentially leading to it entering the airway and causing respiratory complications.
Choice D rationale
Orange gelatin, while seemingly semi-solid, often melts into a thin liquid in the mouth due to body temperature. This change in consistency makes it difficult to control and increases the risk of aspiration in patients with dysphagia. Gelatin's slippery texture further compounds this risk.
