Nursing Elites

1. A client with a diagnosis of myocardial infarction (MI) is prescribed nitroglycerin. What is the primary action of this medication?

• A. Increases heart rate
• B. Lowers blood pressure
• C. Dilates coronary arteries
• D. Reduces myocardial oxygen demand

Correct answer: C

Rationale: The correct answer is C: Nitroglycerin dilates coronary arteries, improving blood flow to the heart muscle. This helps increase oxygen supply to the heart tissue. Option A, 'Increases heart rate,' is incorrect because nitroglycerin does not directly affect heart rate. Option B, 'Lowers blood pressure,' is also incorrect as while nitroglycerin can lower blood pressure, its primary action in the context of MI is related to coronary artery dilation. Option D, 'Reduces myocardial oxygen demand,' is not the primary action of nitroglycerin in the treatment of myocardial infarction; its main action is to increase oxygen supply by dilating coronary arteries.

2. What action should the nurse implement in caring for a client following an electroencephalogram (EEG)?

• A. Monitor the client's vital signs every 4 hours
• B. Assess the client's lower extremities for sensation
• C. Instruct the client to maintain bed rest
• D. Wash any paste from the client's hair and scalp

Correct answer: D

Rationale: The correct action the nurse should implement after an EEG is to wash any paste from the client's hair and scalp. This is crucial to prevent irritation and infection at the EEG site. Monitoring vital signs every 4 hours is not specifically indicated after an EEG. Assessing the client's lower extremities for sensation is unrelated to caring for a client post-EEG. While rest may be recommended after the procedure, there is no standard requirement for a specific duration of bed rest.

3. A client with a diagnosis of hypothyroidism is being treated with levothyroxine (Synthroid). What is the most important information for the nurse to provide?

• A. Take the medication at bedtime.
• B. Take the medication with food.
• C. Report any symptoms of hyperthyroidism.
• D. Discontinue the medication if you feel well.

Correct answer: C

Rationale: The most important information for the nurse to provide to a client with hypothyroidism being treated with levothyroxine is to report any symptoms of hyperthyroidism. Symptoms of hyperthyroidism, such as palpitations or tremors, may indicate overtreatment or excessive dosing of levothyroxine. Prompt reporting of these symptoms is crucial to prevent serious complications. Choices A and B are not the most critical information related to levothyroxine administration. Instructing the client to take the medication at bedtime or with food can be important for adherence but is not as crucial as monitoring for signs of hyperthyroidism. Choice D is incorrect as discontinuing the medication if feeling well can lead to a relapse of hypothyroidism symptoms.

4. A client with a diagnosis of hypertension is prescribed a thiazide diuretic. Which potential side effect should the nurse monitor for?

• A. Hyperkalemia
• B. Hypernatremia
• C. Hypokalemia
• D. Hypoglycemia

Correct answer: C

Rationale: The correct answer is C: 'Hypokalemia.' Thiazide diuretics commonly cause potassium loss, which can lead to hypokalemia. Monitoring potassium levels is essential when a client is taking thiazide diuretics to prevent complications such as cardiac dysrhythmias. Choices A, B, and D are incorrect. Hyperkalemia (choice A) is an elevated level of potassium, which is not typically associated with thiazide diuretics. Hypernatremia (choice B) is an elevated level of sodium, and hypoglycemia (choice D) is low blood sugar, neither of which are directly linked to thiazide diuretic use.

5. The nurse is caring for a client who underwent a total knee replacement yesterday. What activity level should the nurse encourage today?

• A. Bed rest with bathroom privileges only
• B. Frequent, short walks with assistance
• C. Range of motion exercises to the knee every four hours
• D. Leg elevation to reduce swelling

Correct answer: B

Rationale: After a total knee replacement, early ambulation is crucial for promoting circulation and preventing complications like thrombosis. Bed rest should be avoided as it can increase the risk of complications. Range of motion exercises are important but should be performed gradually and not excessively. Leg elevation is beneficial for reducing swelling but should not be the primary activity level encouraged immediately after surgery.
