A nurse is preparing to titrate morphine 6 mg via IV bolus to a client. The amount available is morphine 8 mg/mL. How many mL should the nurse administer per dose?

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

Answer and Explanation

The Correct Answer is ["0.75"]

To calculate the volume of solution, use the formula:

mL = (desired dose in mg / available dose in mg) x 1 mL

Plug in the given values:

mL = (6 mg / 8 mg) x 1 mL

Simplify and solve:

mL = 0.75 x 1 mL

mL = 0.75 mL

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

mL = 0.75 mL

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

A. Remove the nasal cannula while the client eats. B. Attach a humidifier bottle to the base of the ﬂow meter. C. Secure the oxygen tubing to the bed sheet near the client's head. D. Apply petroleum jelly to the nares as needed to soothe mucous membranes.

Correct Answer is B

Explanation

A humidifier bottle adds moisture to the oxygen, which prevents drying and irritation of the nasal mucosa

and enhances gas exchange.

a. Remove the nasal cannula while the client eats. This is not advisable, as the client may become hypoxic during eating, especially if they have pneumonia and impaired lung function. The nurse should monitor the client's oxygen saturation and respiratory status during meals and adjust the oxygen delivery device as needed.

c. Secure the oxygen tubing to the bed sheet near the client's head. This is not safe, as it can cause entanglement, dislodgement, or kinking of the tubing, which can compromise oxygen delivery and cause injury to the client.

d. Apply petroleum jelly to the nares as needed to soothe mucous membranes. This is not recommended, as petroleum products can ignite in the presence of oxygen and cause burns or fire. A water-based lubricant should be used instead.
