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 a preceding zero if necessary. Do not use trailing zeros. Round to the nearest tenth if necessary)
The Correct Answer is ["9"]
Step 1: Calculate the prescribed dose in mg
Dose = 0.5 mg/kg × 90 kg = 45 mg per dose
Step 2: Use the concentration to find the volume (mL) needed
Drug D is available as 25 mg per 5 mL
Set up a proportion:
25 mg / 5 mL = 45 mg / x mL
Step 3: Solve for x
x = (45 × 5) ÷ 25 = 225 ÷ 25 = 9
Final Answer:
9 mL per dose

Correct Answer is B
Explanation
A. Have you tried videos or flash cards? People learn in different ways.: While videos or flashcards might be helpful tools for some, this response doesn't address the primary concern, which is consistency in the approach for memory recall. Reinforcing one method consistently is crucial for individuals with traumatic brain injuries (TBI) to help improve memory retention.
B. It is important to reinforce one consistent method due to the injury.: This is the best response. Individuals with brain injuries, especially those affecting memory, benefit from consistent, structured methods of learning and remembering. Changing the approach frequently can confuse the patient and hinder their progress. Reinforcing one method consistently will provide the brain with a routine to help it form connections and improve memory.
C. Does he have a favorite type of music? Background music helps with memory.: While music can sometimes be used in memory therapies, the suggestion of using music as background for memory enhancement is not a reliable or consistent approach. It doesn't address the need for a structured, consistent method that would be most beneficial in this case.
D. Maybe he is depressed due to the injury, Depression alters concentration.: While depression can affect cognitive functions such as concentration and memory, there is no direct indication in the partner’s statement that depression is the primary concern here. Focusing on consistent memory strategies is more appropriate as a first step.
Correct Answer is A
Explanation
A. A change in the pattern of shortness of breath can be a sign of worsening respiratory or cardiovascular status and may indicate a serious condition such as pulmonary embolism, heart failure, or a pneumothorax. This requires immediate assessment and further investigation to determine the cause.
B. While flank pain (7/10) after receiving oral analgesic could be concerning, the fact that the pain is still significant 15 minutes after medication administration suggests that the pain may not yet be well-controlled. However, this is not as immediately urgent as a change in breathing pattern, so this patient should be assessed after the one with respiratory concerns.
C. Serosanguinous drainage from a JP drain on postoperative day 3 is not uncommon, and this typically does not require immediate intervention unless the drainage increases significantly or becomes more sanguine. This patient should be assessed after the one with a change in shortness of breath.
D. Bilateral wheezes after walking 40 feet, with a pulse oximetry of 96% on room air, is concerning but not as urgent as a change in shortness of breath. The pulse oximetry is within the normal range, and wheezing could be related to mild exertion or an underlying chronic condition (like asthma), but the patient’s condition doesn’t seem to be immediately life-threatening. This patient should be assessed after the patient with shortness of breath.
