Nursing Elites

1. A client has a new prescription for Phenytoin. Which of the following instructions should the nurse include?

• A. Brush and floss your teeth regularly.
• B. Avoid drinking grapefruit juice.
• C. Take this medication with food.
• D. Increase your intake of calcium-rich foods.

Correct answer: A

Rationale: The correct answer is to instruct the client to brush and floss their teeth regularly. Phenytoin can lead to gingival hyperplasia, making oral hygiene crucial to prevent complications. Encouraging good oral care practices helps reduce the risk of adverse effects on the gums and teeth. Avoiding grapefruit juice is not specifically related to Phenytoin. While some medications require intake with food, Phenytoin is usually taken on an empty stomach for better absorption. Increasing calcium-rich foods is not directly associated with Phenytoin therapy.

2. When completing a nursing history for a client taking Simvastatin, which of the following disorders should the nurse identify as a contraindication to adding Ezetimibe to the client's medications?

• A. History of severe constipation
• B. History of hypertension
• C. Active hepatitis C
• D. Type 2 diabetes mellitus

Correct answer: C

Rationale: Ezetimibe is contraindicated in clients with active moderate-to-severe liver disorders, particularly if they are already on a statin like simvastatin. Hepatitis C is a liver condition that can be exacerbated by Ezetimibe, leading to potential complications. Therefore, the nurse should identify active hepatitis C as a contraindication to adding Ezetimibe to the client's medications. Choices A, B, and D are incorrect because they are not directly related to the contraindication of Ezetimibe in clients taking Simvastatin.

3. What is the therapeutic use of Phenytoin?

• A. Replacement in hypothyroidism to restore normal hormonal balance
• B. Diminished accumulation of acid in the gastric lumen with lessened gastroesophageal reflux
• C. Diminished seizure activity, termination of ventricular arrhythmias
• D. Prevention of thrombus formation, prevention of extension of existing thrombi

Correct answer: C

Rationale: Phenytoin is primarily used to diminish seizure activity and is effective in terminating ventricular arrhythmias. It works by stabilizing neuronal membranes, reducing repetitive neuronal firing, and limiting the spread of seizure activity in the brain. While phenytoin does not have a direct role in preventing thrombus formation or extending existing thrombi, it is crucial in managing seizures and certain arrhythmias.

4. Which adverse reaction poses the greatest life-threatening risk when taking Omeprazole?

• A. Chest pain
• B. Constipation
• C. Clostridium difficile-associated diarrhea
• D. Acute interstitial nephritis

Correct answer: C

Rationale: The most life-threatening adverse reaction associated with Omeprazole is Clostridium difficile-associated diarrhea. This condition can be severe and life-threatening due to the potential for dehydration, electrolyte imbalances, and complications such as toxic megacolon. Chest pain, constipation, and acute interstitial nephritis are potential side effects of Omeprazole but are not considered as life-threatening as Clostridium difficile-associated diarrhea. Monitoring for signs of this adverse reaction is crucial, and immediate medical attention should be sought if symptoms develop.

5. Which of the following types of insulin is classified as 'long-acting'?

• A. Lispro (Humalog)
• B. NPH (Humulin N)
• C. Regular insulin (Humulin R)
• D. Glargine (Lantus)

Correct answer: D

Rationale: The correct answer is Glargine (Lantus). Glargine is classified as a long-acting insulin due to its slow, steady release over an extended period, making it suitable for basal insulin requirements. It has a duration of action that can last up to 24 hours, helping to maintain stable blood sugar levels throughout the day. Lispro (Humalog) is a rapid-acting insulin, NPH (Humulin N) is an intermediate-acting insulin, and Regular insulin (Humulin R) is a short-acting insulin, so they are not classified as long-acting insulins.
