The prescription states: “Give drug D 0.5 mg/kg of body weight PO three times a day.” The client’s weight is 90 kg. Drug D is available from the pharmacy as 25 mg per 5 mL. How many mL will the client receive per 1 dose? (Use preceding zeros if necessary. Do not use trailing zeros. Round to the nearest tenth if necessary.)

Answer and Explanation

The Correct Answer is ["9.0"]

Calculation and Answer

Step 1: Determine the total dose required per administration.

Dose required = 0.5 mg/kg × 90 kg
Dose required = 45 mg

Step 2: Determine the concentration of the drug.

Concentration = 25 mg per 5 mL

Step 3: Calculate the volume needed to administer the required dose.

Volume (mL) = Dose required ÷ Concentration
Volume (mL) = 45 mg ÷ (25 mg ÷ 5 mL)
Volume (mL) = 45 mg ÷ 5 mg/mL
Volume (mL) = 9 mL

The client will receive 9.0 mL per dose.

Correct Answer is B

Explanation

Choice A reason: Elevating the client’s head of the bed to 45 degrees is important for promoting optimal lung expansion and reducing the risk of aspiration. However, it is not the first priority when preparing for tracheostomy care. Ensuring adequate oxygenation is more critical in the immediate preparation phase.

Choice B reason: Hyper-oxygenating the client using an Ambu bag is the first priority. This step is crucial to ensure that the client has sufficient oxygen reserves before the tracheostomy care procedure begins. Hyper-oxygenation helps prevent hypoxia during suctioning, which can be particularly important for clients with COPD who may already have compromised respiratory function.

Choice C reason: Opening the suction and tracheostomy kits is necessary for the procedure, but it should be done after ensuring the client is adequately oxygenated. Preparing the equipment is important, but patient safety and oxygenation take precedence.

Choice D reason: Suctioning the client using aseptic technique is a critical part of tracheostomy care to maintain a patent airway and prevent infection. However, this should be done after the client has been hyper-oxygenated to ensure they are stable and to minimize the risk of hypoxia during the procedure.

A. Apply an iodine-soaked sterile dressing. B. Irrigate the wound and apply a dry sterile dressing. C. Apply a dressing and notify the surgeon. D. Apply a sterile dressing soaked with normal saline.

Correct Answer is D

Explanation

Choice A Reason:

Applying an iodine-soaked sterile dressing is not the best initial action. Iodine can be irritating to exposed tissues and may not provide the necessary moisture to protect the underlying tissue. The primary goal is to keep the tissue moist and prevent further damage.

Choice B Reason:

Irrigating the wound and applying a dry sterile dressing is not appropriate in this situation. Irrigation might cause further damage to the exposed tissue, and a dry dressing will not keep the tissue moist, which is crucial for preventing desiccation and promoting healing.

Choice C Reason:

Applying a dressing and notifying the surgeon is important, but the type of dressing is crucial. A dry dressing or an inappropriate dressing material can harm the exposed tissue. The nurse should first apply a moist dressing to protect the tissue and then notify the surgeon.

Choice D Reason:

Applying a sterile dressing soaked with normal saline is the most appropriate initial action. This type of dressing keeps the exposed tissue moist, which is essential for preventing further damage and promoting healing. Normal saline is gentle and will not irritate the tissue, making it the best choice for initial wound care.
