Nursing Elites

1. A client is taking Humulin NPH insulin daily every morning. The nurse reinforces instructions for the client and tells the client that the most likely time for a hypoglycemic reaction to occur is:

• A. 2 to 4 hours after administration
• B. 4 to 12 hours after administration
• C. 16 to 18 hours after administration
• D. 18 to 24 hours after administration

Correct answer: B

Rationale: Humulin NPH is an intermediate-acting insulin with a peak action time of 4 to 12 hours after administration. During this period, the risk of hypoglycemic reactions is highest. It is important for the client to be aware of this timing to prevent, recognize, and manage hypoglycemia effectively.

2. A client with type 2 diabetes mellitus is prescribed metformin (Glucophage). Which instruction should the nurse include in the teaching plan?

• A. Take the medication with meals.
• B. Monitor for signs of hypoglycemia.
• C. Avoid alcohol while taking this medication.
• D. Take the medication at bedtime.

Correct answer: C

Rationale: Clients taking metformin (Glucophage) should avoid alcohol as it can increase the risk of lactic acidosis. Metformin should be taken with meals to reduce gastrointestinal upset. While hypoglycemia is less common with metformin compared to other diabetes medications, clients should still be aware of its symptoms.

3. A client with severe acne is seen in the clinic, and the healthcare provider prescribes isotretinoin. The nurse reviews the client's medication record and would contact the healthcare provider if the client is taking which medication?

• A. Vitamin A
• B. Digoxin (Lanoxin)
• C. Furosemide (Lasix)
• D. Phenytoin (Dilantin)

Correct answer: A

Rationale: Isotretinoin is a metabolite of vitamin A, which can lead to toxicity when taken together. Therefore, it is crucial to avoid concurrent use of vitamin A supplements with isotretinoin. Contacting the healthcare provider to discuss discontinuing vitamin A supplements is important to prevent potential adverse effects. Choices B, C, and D are incorrect as they are not known to interact significantly with isotretinoin.

4. Salicylic acid is prescribed for a client with a diagnosis of psoriasis. The nurse monitors the client, knowing that which of the following would indicate the presence of systemic toxicity from this medication?

• A. Tinnitus
• B. Diarrhea
• C. Constipation
• D. Decreased respirations

Correct answer: A

Rationale: The correct answer is A: Tinnitus. Salicylic acid can lead to systemic toxicity, known as salicylism, which may manifest with symptoms like tinnitus, dizziness, hyperventilation, and mental disturbances. Tinnitus is a common early sign of salicylism and should be monitored closely by the nurse to prevent further complications.

5. A client is prescribed warfarin (Coumadin) for atrial fibrillation. Which statement by the client indicates a need for further teaching?

• A. I will avoid foods high in vitamin K.
• B. I will take the medication at the same time each day.
• C. I will use an electric razor to shave.
• D. I will take aspirin if I have a headache.

Correct answer: D

Rationale: Clients taking warfarin (Coumadin) should avoid aspirin unless prescribed by their healthcare provider, as it can increase the risk of bleeding. The other statements are correct and do not indicate a need for further teaching. Taking aspirin along with warfarin can potentiate the anticoagulant effects of warfarin, leading to an increased risk of bleeding complications.
