A client is ordered to receive 4 g of a medication. The pharmacy has the medication available in a concentration of 160 mg per 5 mL. How many mL should the client receive?
The Correct Answer is ["125"]
To calculate the amount of mL that the client should receive, we need to use the formula:
mL = (g * 5 mL) / mg
where g is the ordered dose of the medication, mg is the concentration of the medication, and mL is the volume of the solution.
Plugging in the given values, we get:
mL = (4 g * 5 mL) / 160 mg
Simplifying, we get:
mL = 0.125 g/mL
Multiplying by 1000 to convert grams to milligrams, we get:
mL = 125 mg/mL
Therefore, the client should receive 125 mL of the solution.

Correct Answer is D
Explanation
A. Coronary artery disease (CAD):
Coronary artery disease primarily affects the blood vessels supplying the heart muscle. Symptoms often include chest pain (angina) rather than pain in the lower extremities. The symptoms described in the scenario are not characteristic of CAD.
B. Arterial embolus:
An arterial embolus is a blood clot or debris that travels through the bloodstream and can block an artery. While it can cause decreased blood flow and pain, the presentation in the lower left leg and foot with relief of pain at rest is more suggestive of peripheral arterial disease (PAD) or intermittent claudication rather than an acute arterial embolus.
C. Raynaud disease:
Raynaud's disease is characterized by episodes of reduced blood flow to the extremities, usually triggered by cold or stress. It typically involves color changes (white, blue, red) in the fingers or toes. The symptoms described, including pain in the lower leg and foot during walking, are not typical of Raynaud's disease.
D. Intermittent claudication:
Intermittent claudication is a symptom associated with peripheral arterial disease (PAD). It involves pain or cramping in the legs during physical activity, such as walking, due to reduced blood flow to the muscles. Rest typically relieves the pain. The observation of a hairless leg and slight edema suggests potential vascular compromise in the lower extremity, supporting the diagnosis of intermittent claudication.
Correct Answer is A
Explanation
A. "Did you have rheumatic fever as a child?"
Rheumatic fever is an inflammatory condition that can affect the heart, especially the heart valves. Rheumatic fever is a known risk factor for the development of valvular heart disease. Asking about a history of rheumatic fever helps identify a potential cause for valve malfunction.
B. "Do you have a family history of valve problems?"
Family history can be relevant in understanding genetic predispositions to certain cardiac conditions. While it may contribute to the overall assessment of cardiac risk, it may not be as directly linked to valve malfunction as a history of rheumatic fever.
C. "Do you have a history of MRSA?"
MRSA (Methicillin-resistant Staphylococcus aureus) is a type of bacterial infection and is not directly associated with valve malfunction. This question may be relevant for other aspects of the client's health but is not specific to ruling out cardiac issues related to valve malfunction.
D. "What over-the-counter medications do you take?"
While knowing the medications a client takes is important for a comprehensive assessment, asking about over-the-counter medications may not be as directly related to ruling out cardiac issues related to valve malfunction. It is more relevant for assessing potential interactions or effects on cardiovascular health.
