The nurse prepares to administer a lidocaine infusion to deliver 3 mg/min. The solution available contains 2 grams of lidocaine in 500 mL of 5% dextrose. How many mL/hr should the nurse set the IV pump? Round to a whole number.
The Correct Answer is ["45"]
Step 1: Convert grams to milligrams
2 grams = 2,000 mg
Step 2: Determine the concentration
2,000 mg in 500 mL
Concentration = 2,000 ÷ 500
Concentration = 4 mg/mL
Step 3: Convert mg/min to mg/hr
3 mg/min × 60 min/hr = 180 mg/hr
Step 4: Calculate mL/hr
mL/hr = Dose (mg/hr) ÷ Concentration (mg/mL)
mL/hr = 180 ÷ 4
mL/hr = 45
Step 5: Round to the nearest whole number
45 = 45 mL/hr
Final Answer: 45 mL/hr

Correct Answer is C
Explanation
Rationale:
A. Although emphasizing privacy is important, this statement does not directly address the client’s cultural or religious preference for a female examiner. Simply stating that all providers respect privacy may be perceived as dismissive, and it fails to reassure the client that their specific request will be honored. Cultural sensitivity requires recognizing and validating the client’s values, not just general privacy assurances.
B. This statement minimizes the client’s cultural and religious beliefs by suggesting that covering the client compensates for the presence of a male examiner. In many Muslim traditions, modesty and gender-specific care are critical. Ignoring these preferences can cause distress, reduce trust in healthcare providers, and potentially discourage the client from seeking care in the future.
C. This response acknowledges and respects the client’s religious and cultural values. It communicates that the healthcare team is willing to accommodate the client’s preference for a female examiner whenever possible, without guaranteeing it in situations where staffing limitations may exist. This approach promotes cultural competence, patient-centered care, and trust in the healthcare relationship, while balancing clinical needs and practical limitations.
D. This response is culturally insensitive, dismissive, and likely to create conflict or distress for the client and their family. It fails to recognize the importance of religious beliefs in patient care, which is essential in culturally competent nursing practice. Such a statement can damage the nurse-client relationship and reduce patient cooperation.
Correct Answer is A
Explanation
Rationale:
A. Acute pancreatitis typically causes sudden, severe, and persistent abdominal pain in the epigastric or upper abdominal region, often radiating to the back. The pain is usually worse when lying flat and may improve slightly when the client leans forward or assumes a fetal position. This classic presentation helps differentiate pancreatitis from other causes of abdominal pain.
B. Pain in the left lower quadrant radiating to the groin is more characteristic of conditions such as diverticulitis, renal colic, or ureteral stones, not pancreatitis.
C. Burning or aching epigastric pain radiating to the umbilicus is more typical of gastritis, peptic ulcer disease, or early appendicitis, rather than the severe, constant pain of acute pancreatitis.
D. These descriptors are not consistent with pancreatitis. Pain in the left lower quadrant radiating to the hip suggests musculoskeletal, renal, or gastrointestinal conditions unrelated to the pancreas.
