1. What is the preferred treatment for a patient with unstable angina admitted with chest pain?

• A. Administer sublingual nitroglycerin
• B. Establish IV access
• C. Auscultate heart sounds
• D. Obtain cardiac enzymes

Correct answer: A

Rationale: The correct answer is to administer sublingual nitroglycerin. Nitroglycerin helps vasodilate coronary arteries, improving blood flow to the heart, relieving chest pain, and preventing cardiac tissue damage. Establishing IV access (choice B) is important but not the preferred initial treatment for unstable angina with chest pain. Auscultating heart sounds (choice C) and obtaining cardiac enzymes (choice D) are relevant assessments but do not address the immediate symptomatic relief needed for a patient with unstable angina and chest pain.

2. What is a characteristic sign of hypokalemia on an ECG?

• A. Flattened T waves
• B. ST elevation
• C. Prominent U waves
• D. Widened QRS complex

Correct answer: A

Rationale: Flattened T waves are a characteristic sign of hypokalemia on an ECG. When potassium levels are low, it can lead to changes in the ECG, such as T wave flattening. This alteration is important to recognize as it indicates potential electrolyte imbalances. ST elevation (Choice B) is not typically associated with hypokalemia but can be seen in conditions like myocardial infarction. Prominent U waves (Choice C) are associated with hypokalemia, but flattened T waves are more specific. Widened QRS complex (Choice D) is not a typical ECG finding in hypokalemia but can be seen in conditions like hyperkalemia.

3. What are the expected ECG findings in hypokalemia?

• A. Flattened T waves
• B. Prominent U waves
• C. Elevated ST segments
• D. Wide QRS complex

Correct answer: A

Rationale: Flattened T waves are the classic ECG finding in hypokalemia. Hypokalemia primarily affects the repolarization phase of the cardiac action potential, leading to T wave abnormalities. While prominent U waves are typically associated with hypokalemia as well, flattened T waves are the most specific and sensitive ECG abnormality seen in hypokalemia. Elevated ST segments and wide QRS complexes are not typically seen in hypokalemia and are more indicative of other electrolyte imbalances or cardiac conditions.

4. A nurse is teaching a group of assistive personnel (AP) about caring for clients who have Alzheimer's disease. Which of the following information should the nurse include in the teaching?

• A. Explain procedures clearly and concisely to the client before initiating care
• B. Encourage a client's engagement in appropriate activities to minimize emotional outbursts
• C. Speak calmly and at a moderate volume to a client who is unable to form words or sentences
• D. Provide supervision to prevent a client from becoming injured or lost

Correct answer: D

Rationale: The correct answer is D because clients with Alzheimer's disease are at risk of wandering and becoming lost. Providing supervision helps prevent them from getting injured or lost. Choice A is incorrect because extensive details may overwhelm clients with Alzheimer's. Choice B is incorrect because limiting activities can lead to boredom and behavioral issues. Choice C is incorrect because speaking calmly and at a moderate volume helps to reduce agitation and confusion in clients with Alzheimer's.

5. What is the first-line treatment for wheezing due to an allergic reaction?

• A. Albuterol via nebulizer
• B. Cromolyn via nebulizer
• C. Methylprednisolone 100 mg IV
• D. Aminophylline 500 mg IV

Correct answer: A

Rationale: The correct answer is A, Albuterol via nebulizer. Albuterol is the first-line treatment for wheezing caused by an allergic reaction because it acts quickly to open the airways by relaxing the muscles in the air passages. Cromolyn (Choice B) is used for asthma prevention rather than acute wheezing. Methylprednisolone (Choice C) and Aminophylline (Choice D) are not the first-line treatments for acute wheezing in the setting of an allergic reaction.
