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 B
Explanation
Choice A rationale:
A lactose-free diet does not contraindicate acupuncture therapy. Lactose intolerance is a digestive condition that does not affect blood clotting or the ability to receive acupuncture safely.
Acupuncture needles are very fine and do not typically cause bleeding. Even if minor bleeding occurs, it is not a concern for individuals without bleeding disorders.
Therefore, a lactose-free diet does not pose a risk for acupuncture.
Choice B rationale:
Thrombocytopenia is a condition characterized by a low platelet count. Platelets are essential for blood clotting. Acupuncture involves the insertion of needles into the skin. This can cause minor bleeding, even when performed correctly.
In individuals with thrombocytopenia, even minor bleeding can be difficult to control and may lead to excessive bruising or hematoma formation.
Therefore, thrombocytopenia is a contraindication to acupuncture therapy due to the increased risk of bleeding complications.
Choice C rationale:
Herniated lumbar disks are a common condition that can cause back pain. Acupuncture is often used to treat back pain, including pain caused by herniated disks.
Studies have shown that acupuncture can be effective in reducing pain and improving function in patients with herniated disks.
Therefore, the presence of herniated lumbar disks does not contraindicate acupuncture therapy.
Choice D rationale:
Latex and strawberry allergies are not contraindications to acupuncture therapy. Acupuncture needles are typically made of stainless steel, which does not contain latex.
Additionally, acupuncture does not involve the use of strawberries or any other substances that are common allergens. Therefore, latex and strawberry allergies do not pose a risk for acupuncture.
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.
