The physician has ordered Zantac elixir 75 mg PO bid for heartburn.

The medication is supplied in 15 mg/mL. How many milliliters will the nurse administer? (Shade CUP #1 to correct dose & LABEL CORRECTLY TO RECEIVE CREDIT)

Choice A rationale

Documenting the error and notifying the supervisor are necessary steps, but they are not the most immediate or comprehensive actions. The priority in a medication error is patient safety, which requires immediate medical assessment and intervention. This step follows after direct patient care and notification of the physician.

Choice B rationale

Administering the original drug and observing for adverse reactions addresses part of the problem, but it does not prioritize immediate medical consultation regarding the mistakenly administered drug. The focus should be on the potential effects of the incorrect medication and timely intervention to mitigate harm.

Choice C rationale

The most appropriate and immediate action is to call the physician to inform them of the medication error. This allows the physician to assess the potential harm to the patient based on the specific drug, dosage, and patient's condition, and to order appropriate interventions. An incident report is crucial for organizational learning and quality improvement.

Choice D rationale

Deciding not to act based on a quick check of allergies or contraindications is highly negligent and unsafe. Even if there are no apparent immediate contraindications, any medication error carries inherent risks and requires a thorough medical evaluation by the physician. This approach prioritizes patient safety over documentation and investigation.

Choice A rationale

Dullness upon percussion indicates increased tissue density, such as in consolidation (e.g., pneumonia), pleural effusion, or a tumor. This occurs because the sound waves are attenuated and dampened by the solid or fluid-filled structures, resulting in a short, high-pitched, thudding sound.

Choice B rationale

Tympany is a drum-like, high-pitched, loud sound typically heard over air-filled organs like the stomach or intestines. When percussing the lungs, tympany suggests a large pneumothorax or a distended abdomen impinging on the thoracic cavity, indicating abnormal air accumulation.

Choice C rationale

Resonance is the expected percussive sound over healthy, air-filled lung tissue. It is a low-pitched, clear, hollow sound produced by the vibration of air within the alveoli and bronchi. This sound indicates normal lung aeration and the absence of significant pathology.

Choice D rationale

Hyperresonance is a louder, lower-pitched sound than normal resonance and suggests an increased amount of air in the lung or pleural cavity, such as in emphysema or pneumothorax. This hyperinflation causes greater vibration and a more boomy quality to the sound.
