(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 ["100"]

Explanation

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

A. Patency of the intravenous line. B. Need for suctioning. C. Integrity of the dressing. D. Level of pain.

Correct Answer is B

Explanation

Suctioning is the priority observation in the client's care, as it prevents airway obstruction and respiratory distress caused by blood, mucus, or secretions. The client has a permanent tracheostomy and cannot cough or clear the airway eﬀectively. The nurse should assess the need for suctioning frequently and perform it as needed, using sterile technique and maintaining oxygenation.

a) Patency of the intravenous line is important, but not the priority observation in the client's care. The intravenous line provides ﬂuids, electrolytes, and medications to the client, but it does not aﬀect the airway patency or oxygenation.
c) Integrity of the dressing is important, but not the priority observation in the client's care. The dressing protects the surgical site from infection and bleeding, but it does not aﬀect the airway patency or oxygenation.
d) Level of pain is important, but not the priority observation in the client's care. The pain can be managed with analgesics and nonpharmacological measures, but it does not aﬀect the airway patency or oxygenation.
