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.
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.
Correct Answer is B
Explanation
B. Maculopapular rash is a potential adverse effect of ceftriaxone. It is a type of skin rash characterized by flat, red areas (macules) and raised, bumpy areas (papules). If a client develops a rash while taking ceftriaxone, it should be reported to the healthcare provider for evaluation.
A. Constipation is not a common adverse effect of ceftriaxone. It is more commonly associated with other medications or medical conditions unrelated to ceftriaxone.
C. Pitting edema is not a common adverse effect of ceftriaxone. It may occur as a result of other medical conditions or medications, but it is not specifically associated with ceftriaxone.
D. Concentrated urine is not a common adverse effect of ceftriaxone.
