The nurse explains to the client the different ways to administer inhalation medications. Which administration technique should be included in the teaching session?(Select All that Apply.)

Metered-dose inhaler

Nebulizer

Hypodermic syringe

Feeding tube syringe

Dry powder inhaler

Answer and Explanation

Correct Answer : A,B,E

A. Metered-dose inhaler (MDI): MDIs deliver a specific dose of medication in aerosol form. They consist of a pressurized canister containing medication and a mouthpiece or mask for inhalation. Patients must coordinate inhalation with actuation to ensure proper medication delivery to the lungs.

B. Nebulizer: Nebulizers convert liquid medication into a fine mist that can be inhaled directly into the lungs. They are commonly used for patients who have difficulty using MDIs or require higher doses of medication. Nebulizers are often used in acute care settings or at home for patients with chronic respiratory conditions.

C. Hypodermic syringe: Hypodermic syringes are used for administering injections subcutaneously, intramuscularly, or intravenously. They are not used for inhalation medication administration.

D. Feeding tube syringe: Feeding tube syringes are used for administering liquid medications or enteral feeds through feeding tubes directly into the gastrointestinal tract. They are not used for inhalation medication administration.

E. Dry powder inhaler (DPI): DPIs deliver medication in powdered form, which is activated by the patient's inhalation. Unlike MDIs, DPIs do not require coordination between actuation and inhalation. Instead, patients inhale forcefully to disperse the medication into their lungs.

Correct Answer is C

Explanation

A) Lowered heart rate:
Dopamine typically increases heart rate as it acts on beta-adrenergic receptors in the heart, leading to increased cardiac contractility and chronotropy. However, at low doses, the effect on heart rate may be minimal compared to higher doses.

B) Decreased conduction through the AV node:
Dopamine may have minimal effects on conduction through the atrioventricular (AV) node, especially at low doses. It primarily acts on adrenergic receptors to increase cardiac contractility and heart rate.

C) Increased urine output.
Dopamine is a medication commonly used to treat shock by improving cardiac output and blood pressure. At low doses, dopamine primarily acts on dopamine receptors in the renal blood vessels, causing vasodilation and increased renal blood flow. This increased renal blood flow leads to increased glomerular filtration rate (GFR) and urine output. Therefore, increased urine output is an expected effect of dopamine infusion at low doses in the treatment of shock.

D) Vasoconstriction of renal blood vessels:
At low doses, dopamine primarily acts on dopamine receptors in the renal blood vessels, causing vasodilation and increased renal blood flow. Vasoconstriction of renal blood vessels is more commonly associated with higher doses of dopamine or with other vasopressor medications such as norepinephrine or phenylephrine.

A. 250 mL/hr and 45 drops/min B. 200 mL/hr and 45 drops/min C. 200 mL/hr and 50 drops/min D. 250 mL/hr and 50 drops/min

Correct Answer is C

Explanation

To calculate the rate of administration in milliliters per hour (mL/hr):

First, find the total volume to be infused: 1000 mL

Next, divide the total volume by the total time in hours: 1000 mL ÷ 5 hours = 200 mL/hr

Therefore, you will administer the solution at a rate of 200 mL/hr.

To calculate the rate of administration in drops per minute (drops/min):

First, find the total drops: 1000 mL × 15 drops/mL = 15,000 drops

Next, divide the total drops by the total time in minutes: 15,000 drops ÷ (5 hours × 60 minutes/hour) = 50 drops/min

Therefore, you will administer the solution at a rate of 200 mL/hr and 50 drops/min.
