The prescription states: “Give drug D 0.5 mg/kg of body weight PO three times a day.” The client’s weight is 90 kg. Drug D is available from the pharmacy as 25 mg per 5 mL. How many mL will the client receive per 1 dose? (Use preceding zeros if necessary. Do not use trailing zeros. Round to the nearest tenth if necessary.)
The Correct Answer is ["9.0"]
Calculation and Answer
Step 1: Determine the total dose required per administration.
- Dose required = 0.5 mg/kg × 90 kg
- Dose required = 45 mg
Step 2: Determine the concentration of the drug.
- Concentration = 25 mg per 5 mL
Step 3: Calculate the volume needed to administer the required dose.
- Volume (mL) = Dose required ÷ Concentration
- Volume (mL) = 45 mg ÷ (25 mg ÷ 5 mL)
- Volume (mL) = 45 mg ÷ 5 mg/mL
- Volume (mL) = 9 mL
The client will receive 9.0 mL per dose.

Correct Answer is D
Explanation
Choice A reason: Asking if the client would like to see a member of the clergy to receive a blessing can be supportive, but it may not directly address the client’s immediate emotional needs. While spiritual support is important, the nurse should first focus on the client’s expressed concerns about their wife.
Choice B reason: Inquiring if the client has children who can help their wife is practical, but it may not address the client’s emotional distress. The nurse should prioritize providing emotional support and facilitating communication between the client and their family.
Choice C reason: Asking if the client has a living will is important for end-of-life planning, but it does not directly address the client’s emotional concerns. This question is more appropriate for a discussion about advance directives rather than an immediate response to the client’s expressed worries
Choice D reason: Encouraging the client to discuss their feelings with their wife is the most appropriate response. It addresses the client’s emotional needs and promotes open communication between the client and their spouse. This can help alleviate some of the client’s anxiety and ensure that their wife is aware of their feelings and concerns.
Correct Answer is B
Explanation
Choice A reason:
Fever and bradypnea are not typical manifestations of asthma. Fever is more commonly associated with infections, and bradypnea (abnormally slow breathing) is not a characteristic symptom of asthma.
Choice B reason:
Dyspnea (shortness of breath) and wheezing are hallmark symptoms of asthma. Asthma is characterized by inflammation and narrowing of the airways, which leads to difficulty breathing and a whistling sound (wheezing) when exhaling. These symptoms are often triggered by allergens, exercise, or respiratory infections.
Choice C reason:
Crackles and a productive cough are more indicative of conditions like pneumonia or chronic bronchitis rather than asthma. Asthma typically involves a dry cough rather than a productive one.
Choice D reason:
A normal chest shape and orthopnea (difficulty breathing when lying flat) are not specific to asthma. While some individuals with severe asthma may develop a barrel chest over time due to chronic overinflation of the lungs, this is not a typical early manifestation.
