Calculate the initial rate for a Heparin infusion. The infusion is ordered as 18 units/kg/hr. The client weighs 90 kg. The concentration of the Heparin bag is 25,000 units/250 mL. You are administering the Heparin drip via an electronic infusion device. Calculate the infusion rate in mL/hr.
The Correct Answer is ["1.44"]
Step 1: Calculate the total units to be given per hour: 18 × 90 = 1620 units/hour Result = 1620 units/hour
Step 2: Determine the concentration of Heparin in 1 mL: 25000 ÷ 250 = 100 units/mL Result = 100 units/mL
Step 3: Calculate the required volume in mL/hr using total units per hour: (1620 ÷ 100) = 16.2 mL/hr Result = 16.2 mL/hr
Final answer 16.2 mL/hr
Question 47
Calculate the initial bolus of Heparin. Heparin is ordered as 80 units/kg. The client weighs 90 kg. How many mL would you administer using a vial of Heparin labeled Heparin 5000 units/mL?
The correct answer is 1.44 mL
Explanation:
Step 1: Calculate the total number of units required for the bolus: 80 × 90 = 7200 units Result = 7200 units
Step 2: Use the vial concentration to find out how many mL deliver 7200 units: (7200 ÷ 5000) = 1.44 mL Result = 1.44 mL
Final answer 1.44 mL

Correct Answer is B
Explanation
Choice A reason: An untidy house and yard may indicate poor organization or neglect but is not specific to hoarding. It could result from various factors, such as depression or physical limitations, and does not inherently pose a dangerous safety risk associated with hoarding behaviors.
Choice B reason: A single path through the yard and house indicates severe accumulation of items, characteristic of hoarding disorder. This creates significant safety hazards, such as fire risks, tripping hazards, or blocked exits, which can impede emergency access and pose immediate dangers to the client’s well-being.
Choice C reason: Neighbor complaints about cats may suggest pet hoarding, a subtype of hoarding disorder. However, without evidence of excessive clutter or unsafe living conditions, this alone is less indicative of dangerous hoarding compared to physical obstructions like a single path through the home.
Choice D reason: A collection of scattered magazines may suggest early hoarding tendencies but does not necessarily indicate a dangerous level of hoarding. It lacks the severity of safety risks, such as blocked pathways or fire hazards, associated with a single path through the home.
Correct Answer is A
Explanation
Choice A reason: Anorexia nervosa involves severe food restriction, leading to malnutrition and weight loss. Ensuring the client eats well and maintains weight directly addresses the core physiological issue, promoting recovery by restoring nutritional balance and supporting organ function, which is critical for effective treatment and long-term health.
Choice B reason: Eating meals together may foster a supportive environment but does not ensure nutritional adequacy or weight maintenance. It may provide emotional support, but without specific focus on the client’s dietary intake and weight restoration, it is less effective in addressing the primary physiological needs of anorexia nervosa.
Choice C reason: Negotiating family conflicts can reduce stress, which may exacerbate anorexia nervosa symptoms. However, it does not directly address the client’s nutritional or weight restoration needs, which are the primary focus in anorexia treatment. Emotional health is secondary to physical recovery in effective education.
Choice D reason: Reducing discussion about troublesome family members may decrease emotional tension but does not address the core issue of anorexia nervosa, which is severe food restriction and weight loss. This approach lacks direct impact on the physiological aspects of recovery, making it less relevant to effective education.
