A client is ordered to receive 1000ml of 0.9% saline over 4 hours. At what rate will the nurse set the IV pump in mL/hr? (Enter a number only).

A. "Take this medication with a small sip of water or on an empty stomach":
This response is not ideal for calcium carbonate. Calcium carbonate is typically taken with food to help increase its absorption and to reduce the risk of gastrointestinal discomfort, such as constipation or bloating. Taking it on an empty stomach could cause irritation and is not the standard guideline for this medication.

B. "This medication should be taken two hours before other medications":
This is the most appropriate response. Calcium carbonate can interfere with the absorption of other medications, particularly those that require an acidic environment for proper absorption, such as certain antibiotics (e.g., tetracyclines) and thyroid medications. Therefore, taking calcium carbonate two hours before or after other medications helps to prevent such interactions.

C. "Place this medication underneath your tongue and let it dissolve":
Calcium carbonate is typically taken orally in tablet form, not sublingually. The medication should not be dissolved under the tongue, as it is not designed for that route of administration. This would be an incorrect instruction.

D. "You can take as many doses of this medication as you need":
This statement is not accurate. Calcium carbonate should be taken as prescribed and in the correct dosage to avoid side effects such as hypercalcemia or kidney stones. Overuse of calcium supplements can lead to serious complications, and it should not be taken "as needed" without specific instructions from the healthcare provider.

A) Cut the 50 mcg/hr patch in half to obtain 25 mcg/hr dosing: Cutting a fentanyl patch in half is not recommended because it can lead to inconsistent dosing. The patches are designed to release medication at a controlled rate, and cutting them could cause the medication to be released too quickly or unevenly, which could result in overdose or insufficient relief of pain. It’s essential to follow the manufacturer's guidelines and avoid altering the patch.

B) Ask pharmacy to send a 25 mcg/hr transdermal patch: The best course of action is to ask the pharmacy to send the correct 25 mcg/hr transdermal patch. This ensures that the patient receives the prescribed dose in the most accurate and safe manner. The 25 mcg/hr patch is formulated to deliver the correct amount of medication, and it will avoid any risk associated with altering the patch.

C) Contact the healthcare provider and request to increase the dose to 50 mcg/hr: Requesting an increase in the dose is premature without a clear justification from the healthcare provider. The healthcare provider decreased the dose to 25 mcg/hr for a reason, possibly due to side effects, effectiveness, or other clinical factors. Altering the prescribed dose without a proper review would be inappropriate. The nurse should follow the current prescribed dose and resolve the issue by requesting the correct patch from the pharmacy.

D) Remove the previous patch and apply the 50 mcg/hr patch in a different location: Switching to the 50 mcg/hr patch without approval could lead to administering an incorrect dose of fentanyl, which can increase the risk of overdose or severe side effects like respiratory depression. The nurse should adhere to the prescribed 25 mcg/hr dose and request the correct patch from the pharmacy rather than substituting with a higher dose patch.
