A nurse is about to administer a daily dose of potassium chloride 20 mEq suspension orally.
The available amount is potassium chloride suspension 10 mEq/mL.
How many mL should the nurse administer?
The Correct Answer is ["2"]
Step 1: Determine the amount of medication needed. The order is for 20 mEq of potassium chloride. The available amount is 10 mEq/mL.
Step 2: Calculate the volume of medication to administer. Volume = Ordered dose ÷ Available concentration Volume = 20 mEq ÷ 10 mEq/mL = 2 mL So, the nurse should administer 2 mL of potassium chloride suspension.

Correct Answer is ["A","D"]
Explanation
Choice A rationale
Metoclopramide is a medication used for stomach and esophageal problems. It is commonly used to treat and prevent nausea and vomiting, to help with emptying of the stomach in people
with delayed stomach emptying, and to help with gastroesophageal reflux disease. The antiemetic action of metoclopramide is due to its antagonist activity at D2 receptors in the chemoreceptor trigger zone in the central nervous system — this action prevents nausea and vomiting triggered by most stimuli.
Choice B rationale
While metoclopramide does have an effect on the muscles of the gastrointestinal tract, it does not work by relaxing them. Instead, it works by blocking dopamine receptors, which in turn stimulates motility in the upper gastrointestinal tract without stimulating gastric, biliary, or pancreatic secretions. This increased motility helps to speed up the rate at which the stomach empties into the intestines.
Choice C rationale
Metoclopramide does not work by decreasing gastric acid secretions. In fact, one unique property of this drug is that it does not increase gastric acid secretion. Its primary mechanism of action is to block dopamine receptors, thereby increasing muscle contractions in the upper digestive tract.
Choice D rationale
This is correct. Metoclopramide enhances gastric emptying. It is used to treat conditions like gastroesophageal reflux disease and diabetic gastroparesis, where delayed gastric emptying is a problem. By blocking dopamine receptors, metoclopramide increases muscle contractions in the upper digestive tract, speeding up the rate at which the stomach empties into the intestines.
Correct Answer is B
Explanation
Choice A rationale
The Scale for Assessment of Negative Symptoms (SANS) is a tool used to assess negative symptoms in schizophrenia and is not typically used in the assessment of cognitive disorders.
Choice B rationale
The Mental Status Examination (MSE) is a key part of the clinical assessment process in psychiatric practice. It is a structured way of observing and describing a patient’s current state of mind, under the domains of appearance, attitude, behavior, mood and affect, speech, thought process, thought content, perception, cognition, insight, and judgement.
Choice C rationale
The Abnormal Involuntary Movements Scale (AIMS) is a rating scale that measures involuntary movements known as tardive dyskinesia (a side effect of long-term use of antipsychotic drugs). It is not typically used in the assessment of cognitive disorders.
Choice D rationale
The Mini-Mental State Examination (MMSE) is a commonly used test for complaints of memory problems or when a diagnosis of dementia is being considered. However, in this case, the MSE would be a more comprehensive tool.
