A client is ordered to receive atropine 0.3 mg IV stat. Atropine 0.4 mg per mL is available. How many milliliters will the nurse administer?

Answer and Explanation

The Correct Answer is ["0.75"]

The nurse needs to calculate the correct dose of atropine for a client who has a prescription for 0.3 mg IV stat. The nurse knows that atropine is a medication that blocks the effects of the parasympathetic nervous system and is used to treat bradycardia, heart block, and some types of poisoning.

To find out how many milliliters of atropine the nurse will administer, the nurse can use the formula:

Dose ordered / Dose available = Volume to administer

Plugging in the values, the nurse gets:

0.3 mg / 0.4 mg per mL = 0.75 mL

Therefore, the nurse will administer 0.75 mL of atropine to the client IV stat.

Correct Answer is C

Explanation

A. Partial non-rebreathing mask:

This mask delivers higher concentrations of oxygen than a nasal cannula. It has a reservoir bag that allows the client to rebreathe some exhaled air, increasing the oxygen concentration delivered. However, it may not be necessary for a client with mild shortness of breath and slightly reduced oxygen saturation.

B. Simple (Oxy Plus) mask:

The simple mask provides a higher concentration of oxygen than a nasal cannula but lacks the reservoir bag found in the non-rebreathing mask. It is generally used for moderate oxygen needs. However, it might be more than what is required for a client with mild shortness of breath and slightly reduced oxygen saturation.

C. Nasal cannula:

Nasal cannulas are commonly used for clients with mild respiratory distress. They deliver a lower to moderate concentration of oxygen and are well-tolerated by most clients. They are suitable for individuals with mild shortness of breath and can be adjusted based on the required flow rate.

D. Non-rebreathing mask:

The non-rebreathing mask provides the highest concentration of oxygen among the options listed. It includes a reservoir bag to deliver a higher oxygen concentration. It is typically reserved for clients with higher oxygen requirements. For a client with mild shortness of breath and slightly reduced oxygen saturation, this may be more than necessary.

A. “Did you have rheumatic fever as a child?” B. “Do you have a family history of valve problems?” C. “Do you have a history of MRSA?” D. “What over-the-counter medications do you take?”

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.
