The home care nurse is caring for an older adult client who has type 1 diabetes. The client has visual impairment and cannot read the numbers on the syringe when preparing insulin for administration nor afford the cost of prefilled auto syringes.
What strategy might the nurse use to help this client comply with insulin needs between visits?

Prepare a week’s supply of syringes and refrigerate.

Ask a neighbor to come over every day to prepare the medication.

Have the client use a magnifying glass.

Change the client to oral antidiabetics.

Answer and Explanation

The Correct Answer is C

This strategy can help the client read the numbers on the syringe and prepare the correct dose of insulin. A magnifying glass is also an affordable and accessible tool for the client.

Choice A is wrong because preparing a week’s supply of syringes and refrigerating them can affect the potency and sterility of insulin.

It can also increase the risk of errors or confusion.

Choice B is wrong because asking a neighbor to come over every day to prepare the medication can compromise the client’s privacy and independence.

It can also be unreliable and inconvenient for both parties.

Choice D is wrong because changing the client to oral antidiabetics is not possible for type 1 diabetes.

People with type 1 diabetes need to take insulin for life because their pancreas cannot make insulin.

Oral antidiabetics are only effective for people with type 2 diabetes who have functioning pancreatic beta cells

Correct Answer is B

Explanation

This is because antiemetics should be given to prevent motion sickness rather than after nausea or vomiting develop. Taking the medication 30 minutes before departing allows enough time for the drug to be absorbed and reach its peak effect.

Choice A is wrong because avoiding eating or drinking for 6 hours before the trip may cause dehydration and low blood sugar, which can worsen nausea and vomiting.

It is better to eat a light meal or snack before the trip and avoid spicy, greasy, or acidic foods.

Choice C is wrong because taking two doses if relief is not achieved may cause overdose and adverse effects.

Antiemetics should be taken as prescribed and not exceeded without consulting a doctor.

Choice D is wrong because increasing fluid intake to prevent urinary retention is not relevant for motion sickness.

Urinary retention is a possible side effect of some antiemetics, such as anticholinergics, but it is not a common problem for most people.

Fluid intake should be moderate and not excessive to avoid stomach distension.

A. 08:00. B. 22:00. C. 06:00. D. 16:00.

Correct Answer is C

Explanation

This is because cortisol exhibits a proper 24-h circadian rhythm that affects the cardiovascular system and other organs. Cortisol levels are normally low at the beginning of sleep and high at the moment of awakening. Taking corticosteroids at this time mimics the natural cortisol rhythm and may reduce side effects such as adrenal suppression, sleep disturbances and cardiovascular complications.

Choice A is wrong because taking corticosteroids at 08:00 may not coincide with the client’s natural cortisol peak and may cause insomnia or unpleasant dreams.

Choice B is wrong because taking corticosteroids at 22:00 may disrupt the client’s sleep quality and increase the risk of nocturnal hypertension.

Choice D is wrong because taking corticosteroids at 16:00 may interfere with the client’s natural cortisol decline and cause hyperglycemia or dyslipidemia.
