A nurse is preparing to administer regular and NPH insulin to a client. Which of the following actions should the nurse take?

Mix the medications in a 3-mL syringe.

Inject air into the regular vial first.

Administer the medications in two separate syringes.

Withdraw the NPH insulin last.

Answer and Explanation

The Correct Answer is D

D. Drawing the NPH last ensures that it does not contaminate the short acting insulin. The regular insulin should be drawn first.
A. Regular and NPH insulin should not be mixed together in a single syringe prior to administration. Mixing them could alter their action profiles and affect their effectiveness.
B. While injecting air into the vial before withdrawing medication helps prevent negative pressure and facilitates easy withdrawal of the medication, it should be done for each vial individually, not specifically for the regular insulin vial.
C. The medication should be drawn up into the same syringe before administration to the patient.

Correct Answer is A

Explanation

A. Renal function typically declines with age, leading to a decrease in glomerular filtration rate (GFR) and renal blood flow. As a result, medications may be excreted more slowly from the body, leading to an increased risk of drug accumulation and potential toxicity. Adjustments in medication dosages or dosing intervals may be necessary to account for this age-related change.
B. Brain receptors do not change significantly. However, older adults may require lower doses to achieve the same therapeutic effect due to reduced receptor sensitivity.
C. Gastric emptying tends to slow down with age rather than increase. Delayed gastric emptying can affect the absorption of orally administered medications, leading to unpredictable drug levels and potentially reduced efficacy.
D. Hepatic function generally decreases with age, leading to a decline in the metabolic capacity of the liver. This can result in slower drug metabolism and clearance, prolonging the duration of action of medications and increasing the risk of adverse effects.

A. Take your albuterol when you are having difficulty breathing.&quot B. Take the salmeterol 2 times each day.&quot C. Rinse out your mouth after taking the fluticasone

Correct Answer is ["A","B","C"]

Explanation

Albuterol belongs to a class of medications known as beta-adrenergic agonists, specifically beta-2 selective agonists. When inhaled, albuterol binds to beta-2 adrenergic receptors located on the smooth muscle cells lining the airways in the lungs. Activation of these receptors leads to relaxation of the smooth muscles surrounding the bronchial tubes, causing them to widen (bronchodilation). By dilating the airways, albuterol helps to reduce airway resistance and increase airflow into and out of the lungs, making it easier to breathe during an asthma attack.

One should hold breath for 5 to 10 seconds after inhalation of the puff.

Salmeterol is a long-acting beta-adrenergic agonist (LABA) bronchodilator commonly used for the maintenance treatment of asthma and chronic obstructive pulmonary disease (COPD). Salmeterol is usually prescribed for twice-daily dosing.

One should wait for 2 minutes between two puffs.

Fluticasone is a corticosteroid medication that is inhaled into the lungs to reduce inflammation in the airways. If these particles remain in the mouth, they can increase the risk of developing oral thrush, which is a fungal infection caused by Candida albicans. Rinsing the mouth with water after using the inhaler helps to remove any residual medication particles, reducing the risk of oral thrush.
