A client has received a prescription for loratadine suspension, 10 mg to be taken orally once a day. The bottle is labeled as "Loratadine for Oral Suspension, USP 5 mg per 5 mL." How many teaspoons should the nurse instruct the client to take? (Please enter the numerical value only.)
The Correct Answer is ["2"]
Step 1: We need to find out how many mL contain 10 mg of loratadine. Since 5 mg of loratadine is in 5 mL, we can set up a proportion to find out how many mL contain 10 mg.
So, 5 mg is to 5 mL as 10 mg is to X mL.
This gives us the equation: (5 mg ÷ 5 mL) = (10 mg ÷ X mL)
Step 2: Solving for X gives us X = (10 mg × 5 mL) ÷ 5 mg
Step 3: Simplifying gives us X = 10 mL
So, the client needs to take 10 mL of the loratadine suspension to get a dose of 10 mg.
Now, we need to convert this volume in mL to teaspoons, using the conversion factor you provided (1 teaspoon = 5 mL).
Step 4: We set up the conversion as follows: 10 mL × (1 tsp ÷ 5 mL)
Step 5: Simplifying gives us 2 tsp
So, the nurse should instruct the client to take 2 teaspoons of the loratadine suspension.

Correct Answer is D
Explanation
Choice A reason: Avoiding sunscreen is not recommended as it increases the risk of skin cancer; vitamin D can be obtained safely through diet and supplements.
Choice B reason: While it is true that vitamin D and calcium are balanced with phosphorus, this statement does not directly encourage compliance with supplementation.
Choice C reason: Although calcium uses vitamin D produced by sunlight exposure, relying solely on sunshine is not sufficient, especially for individuals at risk of osteoporosis.
Choice D reason: Emphasizing that vitamin D enhances calcium absorption into the bone provides a clear rationale for the client to comply with the supplementation regimen.
Correct Answer is D
Explanation
Choice A reason: Elevated blood pressure is a concern but not as immediately threatening as some other symptoms associated with mitral valve stenosis.
Choice B reason: A rapid, irregular heart rate could indicate atrial fibrillation, which is common in mitral valve stenosis, but it is not as urgent as blood-tinged sputum.
Choice C reason: Swollen feet and ankles suggest fluid retention, which is a concern in mitral valve stenosis but not as immediate as hemoptysis.
Choice D reason: Blood-tinged sputum indicates hemoptysis, which can be a sign of pulmonary edema or other serious complications requiring immediate intervention. This symptom is the most urgent and could signify a potentially life-threatening condition.
