The provider orders Ampicillin 0.4g IM every 6 hours, Pharmacy has provided 250 mg per mL. How many will the nurse administer?
The Correct Answer is ["1.6"]
Calculation:
- Convert the Ordered Dose from grams (g) to milligrams (mg).
Ordered Dose = 0.4 g
Conversion factor = 1 g = 1,000 mg
Ordered Dose (mg) = 0.4 g x 1,000 mg/g
= 400 mg
- Identify the Available medication:
Ordered Dose (D) = 400 mg
Available Dose (H) = 250 mg
Quantity (Q) = 1 mL
Volume (mL) = (Dose Ordered (D) / Dose Available (H)) x Quantity (Q)
= (400 mg / 250 mg) x 1 mL
= 1.6 x 1 mL
= 1.6 mL

Correct Answer is C
Explanation
A. Left groin has minimal bruising: Minimal bruising at the catheter insertion site is an expected finding after balloon angioplasty. It generally does not indicate a complication and can be monitored routinely.
B. Client reports a pain level of 3/10: Mild pain is expected post-procedure and is usually manageable with standard analgesics. While it should be addressed, it does not signal an acute vascular or procedural complication.
C. Left leg with weakened pedal pulse and is cool to the touch: These findings indicate possible arterial occlusion, compromised circulation, or thrombosis in the treated limb, which is a serious complication after angioplasty. Immediate assessment and intervention are required to prevent tissue ischemia and limb loss.
D. Blood pressure 154/78 mmHg: Mild to moderate hypertension may occur post-procedure but is not immediately life-threatening. Blood pressure should be monitored, but it is less urgent than signs of impaired perfusion in the affected limb.
Correct Answer is D
Explanation
A. “I am awakened by the need to urinate at night”: Nocturia can occur with both left- and right-sided heart failure but is not as specific for pulmonary congestion or left-sided failure. It is a secondary symptom.
B. “I have experienced blurred vision on several occasions”: Blurred vision may relate to hypertension or other conditions, but it is not a classic indicator of left-sided heart failure.
C. “I have been drinking more water than usual”: Increased thirst is not a hallmark of left-sided heart failure and may indicate other conditions such as diabetes or dehydration.
D. “I must stop halfway up the stairs to catch my breath”: Exertional dyspnea is a hallmark symptom of left-sided heart failure. It occurs due to pulmonary congestion and decreased cardiac output, making this statement the most concerning for left-sided HF.
