Which medication order is written appropriately?
Metformin 0.5 g PO
Methotrexate 15.0 mg PO
Meropenem 1.0 g IV
None of the above
The Correct Answer is C
Choice A rationale:
Incorrect dosage form: Metformin is typically administered orally as a tablet or liquid suspension, not as a powder for reconstitution (PO).
Missing route of administration: The medication order does not specify the route of administration, such as oral (PO), intravenous (IV), or intramuscular (IM).
Potential for medication errors: The lack of clarity in the medication order could lead to errors in administration, such as giving the wrong dose or administering the medication by the wrong route.
Choice B rationale:
Incorrect dosage unit: Methotrexate is typically administered in milligrams (mg), not grams (g).
Potential for overdose: The order for 15.0 g of methotrexate is a very high dose that could lead to serious adverse effects, including toxicity and death.
Choice C rationale:
Correctly written: The medication order specifies the drug name (meropenem), the dose (1.0 g), the dosage form (IV), and the route of administration (IV).
Appropriate dosage range: The dose of 1.0 g of meropenem is within the typical dosage range for this antibiotic.
Clear and concise: The medication order is clear, concise, and easy to understand, which helps to reduce the risk of medication errors.
Choice D rationale:
Incorrect: While choices A and B are both incorrect, choice C is a correctly written medication order.

Correct Answer is A
Explanation
Choice A rationale:
Hemorrhoids are swollen veins in the anus and rectum that can cause pain, itching, and bleeding. Sitz baths are a common and effective treatment for hemorrhoids because they can help to:
Reduce inflammation and pain Promote healing
Relax the anal sphincter muscles Cleanse the anal area
Warm water helps to increase blood flow to the area, which can help to reduce swelling and inflammation. The water also helps to soothe and cleanse the irritated tissues.
Sitz baths are typically taken for 10-15 minutes at a time, several times a day. They can be taken in a bathtub or a special sitz bath basin that fits over a toilet seat.
Choice B rationale:
A fractured right arm would not benefit from a sitz bath. Sitz baths are specifically for treating the anal and rectal area.
Choice C rationale:
An abscessed tooth would not benefit from a sitz bath. Sitz baths are specifically for treating the anal and rectal area.
Choice D rationale:
Painful back muscle spasms would not benefit from a sitz bath. Sitz baths are specifically for treating the anal and rectal area.
Correct Answer is ["B","C","E"]
Explanation
Choice B rationale:
Heart rate: During a stress response, the sympathetic nervous system is activated, leading to a release of hormones such as adrenaline and cortisol. These hormones increase heart rate, preparing the body for a "fight or flight" response. A heart rate of 132 beats per minute is significantly elevated compared to a normal resting heart rate of 60-100 beats per minute, suggesting a stress response.
Choice C rationale:
Pupil dilation: Pupil dilation is another physiological change associated with the activation of the sympathetic nervous system during stress. The dilation allows more light to enter the eyes, enhancing visual acuity and awareness of surroundings, which can be helpful in responding to potential threats.
Choice E rationale:
Difficulty sleeping: Stress can negatively impact sleep in several ways. It can cause racing thoughts, anxiety, and physical tension, making it difficult to fall asleep and stay asleep. Sleep disturbances are a common symptom of stress and can further exacerbate its effects.
Rationale for incorrect choices:
Choice A: Blood glucose level can be affected by stress, but a low blood glucose level of 36 mg/dL is more likely to be due to other causes such as hypoglycemia or insulin therapy. It's not a direct indicator of a stress response.
Choice D: Blood pressure can increase during stress, but a blood pressure of 104/56 mmHg is within the normal range and does not necessarily indicate a stress response.
