An adult female client with type 1 diabetes mellitus is receiving NPH insulin 35 units each morning. Which finding should the practical nurse (PN) document as evidence that the amount of insulin is inadequate?
States her feet are constantly cold along with feeling numb
Consecutive evening serum glucose greater than 260 mg/dL
A wound on the ankle that starts to drain and becomes painful
Reports nausea in the morning but still able to eat breakfast
The Correct Answer is B
The correct answer and explanation is:
b) Consecutive evening serum glucose greater than 260 mg/dL.
This is the finding that the PN should document as evidence that the amount of insulin is inadequate for the client with type 1 diabetes mellitus. Consecutive evening serum glucose greater than 260 mg/dL indicates hyperglycemia, which means that the client's blood sugar is too high and not well controlled by the insulin dose.
The PN should report this finding to the healthcare provider and expect a possible adjustment in the insulin regimen.
a) States her feet are constantly cold along with feeling numb.
This is not the finding that the PN should document as evidence that the amount of insulin is inadequate for the client with type 1 diabetes mellitus.
States her feet are constantly cold along with feeling numb may indicate peripheral neuropathy, which is a complication of diabetes that affects the nerves in the feet and legs. It is caused by chronic high blood sugar levels over time, not by a single dose of insulin.
c) A wound on the ankle that starts to drain and becomes painful.
This is not the finding that the PN should document as evidence that the amount of insulin is inadequate for the client with type 1 diabetes mellitus. A wound on the ankle that starts to drain and becomes painful may indicate an infection, which is a risk factor for diabetic clients due to impaired wound healing and immune function. It is not directly related to the insulin dose, although it may affect the blood sugar levels and require more insulin.
d) Reports nausea in the morning but still able to eat breakfast.
This is not the finding that the PN should document as evidence that the amount of insulin is inadequate for the client with type 1 diabetes mellitus. Reports nausea in the morning but still able to eat breakfast may indicate morning sickness, which is a common symptom of pregnancy. It is not related to the insulin dose, although it may affect the blood sugar levels and require more frequent monitoring and adjustment.

Correct Answer is A
Explanation
Choice A rationale:
The client's statement, "I should avoid foods that are high in vitamin K," indicates an understanding of the medication. Warfarin is an anticoagulant medication that works by inhibiting vitamin K-dependent clotting factors. Consistent intake of vitamin K-containing foods helps maintain a stable INR (International Normalized Ratio) and warfarin's effectiveness. Clients on warfarin should be educated about avoiding drastic changes in their vitamin K intake.
Choice B rationale:
Taking warfarin with food or on an empty stomach doesn't significantly impact its efficacy. Therefore, this statement is not indicative of the client's understanding of the medication.
Choice C rationale:
The statement "I should report any unusual bleeding or bruising to my provider" is important but doesn't specifically reflect an understanding of warfarin. It's a general caution for anyone taking anticoagulants.
Choice D rationale:
While it's important to avoid excessive use of medications like aspirin that can increase the risk of bleeding, this statement doesn't directly demonstrate an understanding of warfarin itself.
Correct Answer is A
Explanation
Choice A rationale:
The combination of trimethoprim and sulfamethoxazole has a synergistic effect, which means that the two drugs work together to inhibit bacterial growth more effectively than either drug alone. This combination is commonly used to treat urinary tract infections (UTIs) caused by susceptible bacteria.
Choice B rationale:
The combination of trimethoprim and sulfamethoxazole does not have an additive effect that reduces the dosage and frequency of administration of each drug. Instead, it is prescribed as a fixed combination with specific dosages of each drug.
Choice C rationale:
The combination of trimethoprim and sulfamethoxazole does not have an antagonistic effect that prevents the development of resistance to either drug. In fact, the combination is chosen because it covers a broader spectrum of bacteria and reduces the likelihood of resistance development.
Choice D rationale:
The combination of trimethoprim and sulfamethoxazole does not have a selective effect that targets only the bacteria causing the UTI and spares the normal flora. It affects a wide range of bacteria, including both pathogenic and normal flora.
