(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 ["100"]

To calculate the infusion rate, use the formula:

mL/hr = (volume of solution in mL / time of infusion in hr) x 60 min/hr

Plug in the given values:

mL/hr = (50 mL / 0.5 hr) x 60 min/hr

Simplify and solve:

mL/hr = 100 x 60 min/hr

mL/hr = 100 mL/hr

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

mL/hr = 100 mL/hr

Correct Answer is C

Explanation

Increasing ﬂuid intake helps to hydrate the mucous membranes and thin the respiratory secretions, which facilitates expectoration and improves gas exchange.

Encourage coughing and deep breathing. This is beneficial for clearing the airways and preventing atelectasis, but it does not directly aﬀect the viscosity of the secretions.
Encourage regular use of the incentive spirometer. This is helpful for expanding the lungs and preventing complications such as pneumonia or pleural eﬀusion, but it does not inﬂuence the consistency of the secretions.
Encourage the client to ambulate frequently. This is important for promoting circulation and mobility, but it does not have a significant eﬀect on the thinning of the secretions.

Correct Answer is ["2"]

Explanation

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
