(Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["2"]

2 capsules

To calculate the number of capsules, use the formula:

capsules = (desired dose in mg / available dose in mg) x 1 capsule

Plug in the given values:

capsules = (300 mg / 150 mg) x 1 capsule

Simplify and solve:

capsules = 2 x 1 capsule

capsules = 2 capsules

Round to the nearest whole number and add a leading zero if needed:

capsules = 2 capsules

Correct Answer is ["10"]

Explanation

To calculate the amount of mL to administer, the nurse should use the following formula:

(mg ordered / mg available) x mL available = mL to administer

Substituting the values from the question, the nurse should do the following:

(500 mg / 250 mg) x 5 mL = 10 mL

Therefore, the nurse should administer 10 mL of amoxicillin suspension.

A. Provide the client with a low protein diet. B. Instruct the client to use pursed-lip breathing. C. Restrict the client's ﬂuid intake to less than 2 L/day. D. Have the client use the early-morning hours for exercise and activity.

Correct Answer is B

Explanation

Pursed-lip breathing is a technique that helps clients with COPD to exhale more eﬀectively and prevent air trapping in the lungs. It also reduces dyspnea and improves oxygenation.

a) A low protein diet is not recommended for clients with COPD, as they need adequate protein intake to maintain muscle mass and prevent malnutrition.

c) Fluid restriction is not necessary for clients with COPD, unless they have signs of ﬂuid overload or heart failure. Adequate hydration helps to thin secretions and facilitate expectoration.

d) Early-morning hours are not the best time for exercise and activity for clients with COPD, as they may experience more shortness of breath and fatigue due to diurnal variations in lung function. A better time would be mid-morning or afternoon, after taking bronchodilators and clearing secretions.
