Nursing Elites

1. A healthcare provider is preparing to administer metoprolol to a client. Which of the following findings should the provider identify as a contraindication to receiving this medication?

• A. Bradycardia
• B. Hypertension
• C. Fever
• D. Rash

Correct answer: A

Rationale: Metoprolol, a beta-blocker, is contraindicated in clients with bradycardia as it can further lower the heart rate, potentially leading to more serious complications. Bradycardia is defined as a heart rate below 60 beats per minute, and administering metoprolol in such cases can exacerbate this condition, causing adverse effects on cardiac output. Hypertension, fever, and rash are not contraindications for metoprolol administration.

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

• A. Avoid drinking grapefruit juice.
• B. Take the medication with your evening meal.
• C. Increase your intake of leafy green vegetables.
• D. Stop taking the medication if you experience muscle pain.

Correct answer: A

Rationale: The correct answer is A: 'Avoid drinking grapefruit juice.' Grapefruit juice should be avoided when taking Atorvastatin because it can increase the blood levels of the medication, potentially leading to a higher risk of adverse effects like muscle pain and liver damage. It is important to follow this instruction to ensure the safe and effective use of Atorvastatin. Choices B, C, and D are incorrect. Taking Atorvastatin with food, specifically a low-fat meal, is recommended, but it is not necessary to specify the evening meal. While increasing intake of leafy green vegetables is generally beneficial for health, it is not a specific instruction for Atorvastatin. Lastly, stopping the medication if one experiences muscle pain is not advisable without consulting a healthcare provider, as muscle pain can be a symptom of a serious side effect of Atorvastatin that requires medical attention.

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. A client with Subacute Bacterial Endocarditis is receiving Streptomycin IM among other antibiotics. For which of the following manifestations should the nurse monitor as an adverse effect of this medication?

• A. Extremity paresthesias
• B. Urinary retention
• C. Severe constipation
• D. Complex partial seizures

Correct answer: A

Rationale: The correct answer is extremity paresthesias. Streptomycin, used to treat infections like Subacute Bacterial Endocarditis, can cause paresthesias in the hands and feet as an adverse effect. Monitoring for this symptom is vital to detect and manage it promptly. Choices B, C, and D are incorrect because urinary retention, severe constipation, and complex partial seizures are not commonly associated adverse effects of Streptomycin.

5. A client with cancer is prescribed methotrexate. Which supplement should the healthcare provider recommend to reduce the risk of methotrexate toxicity?

• A. Folic acid
• B. Magnesium
• C. Vitamin D
• D. Iron

Correct answer: A

Rationale: The correct answer is folic acid. Methotrexate is a folic acid antagonist, and supplementing with folic acid can help reduce the risk of methotrexate toxicity. Folic acid supplementation is commonly recommended to counteract the effects of methotrexate on folate metabolism. Magnesium, Vitamin D, and Iron are not specifically indicated to reduce the risk of methotrexate toxicity and therefore are incorrect choices in this scenario.
